Description:FIELD OF THE INVENTION

[0001] The present invention pertains to the technical field of medical assistance rehabilitation equipment, specifically a customized shoulder rehabilitation assistive device designed to support users through multiple phases of shoulder rehabilitation, offering tailored therapeutic functions that aid in recovery, improve mobility, and ensure effective rehabilitation, enhancing the overall therapeutic process for the user’s shoulder recovery.

BACKGROUND OF THE INVENTION

[0002] Shoulder rehabilitation is crucial for individuals recovering from injuries, surgeries, or chronic conditions affecting the shoulder joint, which is one of the most mobile yet vulnerable parts of the body. The need for shoulder rehabilitation arises from the complex structure and function of the shoulder, which allows for a wide range of motions essential in daily activities and sports. Injury or dysfunction in this area can lead to pain, stiffness, and limited mobility, severely impacting quality of life. Rehabilitation is vital for restoring normal movement, strength, and flexibility, as well as preventing future injuries. Shoulder rehabilitation involves targeted exercises, manual therapy, and modalities like heat, cold, or electrical stimulation, tailored to the individual’s specific condition. Early and consistent rehabilitation helps in minimizing the risk of permanent damage, reducing pain, and improving overall function. Additionally, proper rehabilitation aids in regaining muscle balance, enhancing posture, and facilitating smooth joint movement. The importance of shoulder rehabilitation cannot be overstated, as it promotes healing, prevents further complications, and ensures the return to a pain-free, active lifestyle.

[0003] Traditional assistance and guidance for shoulder rehabilitation typically involve physical therapy sessions, where a trained therapist evaluates the patient’s condition and provides exercises to restore movement, strength, and function. These exercises are often tailored to the individual’s injury or surgery, including stretches, strength training, and mobility exercises. Patients are given hands-on assistance from the therapist and are instructed on how to perform these exercises at home. While this approach can be effective, it has several drawbacks. Traditional rehabilitation may require frequent visits to the therapist, leading to time and cost constraints for patients. Additionally, the exercises prescribed may not always be closely monitored, leading to inconsistent adherence and progress tracking. Moreover, the approach relies heavily on the therapist’s expertise, which can vary, potentially affecting the quality of care. Patients may also struggle to remember or correctly follow the prescribed exercises at home, reducing the rehabilitation's effectiveness. Finally, traditional methods may lack real-time feedback, making it difficult for patients to correct their movements or adjust to changes in their condition.

[0004] CN104622668A is a bionic shoulder joint movement rehabilitation training apparatus. A base support system is placed on the ground, a bilateral bionic shoulder blade linear movement mechanism is fixedly connected with the base support system and is in revolving-pair connection with a bionic shoulder blade rotation movement mechanism, a bionic glenohumeral joint movement mechanism is in revolving-pair connection with the bionic shoulder blade rotation movement mechanism, and an auxiliary upper arm support system is fixedly connected with the bionic glenohumeral joint movement mechanism. By the arrangement, various must actions of shoulder joint rehabilitation training can be realized, and bilateral linear movement and rotation movement needed in the shoulder joint training for shoulder blades are realized apart from forward bending and backward extension, abduction-adduction and inward revolving and outward revolving of the shoulder blades. The bionic shoulder joint movement rehabilitation training apparatus is simple in structure, comfortable to wear, flexible to adjust, soft in movement, safe and reliable and capable of performing comprehensive rehabilitation training for patients with shoulder joint movement dysfunctions.

[0005] CN220554538U comprises a supporting plate, two arc-shaped plates are arranged on the front face of the supporting plate, arc-shaped grooves are formed in the side faces, close to each other, of the two arc-shaped plates, and arc-shaped blocks are connected to the inner walls of the two arc-shaped grooves in a sliding mode; the side faces, close to each other, of the two arc-shaped blocks are jointly and fixedly connected with a holding rod, two sliding holes are formed in the front face of the supporting plate, sliding blocks are slidably connected to the inner walls of the two sliding holes, and connecting plates are fixedly connected to the back faces of the two sliding blocks. The side faces, close to each other, of the two connecting plates are jointly and fixedly connected with an adjusting plate, a transmission screw ring is fixedly embedded in the upper surface of the adjusting plate, the inner ring of the transmission screw ring is in threaded connection with a transmission screw rod, and the back face of the supporting plate is fixedly connected with a bearing seat. According to the shoulder joint rehabilitation treatment device, the shoulder joint of a patient can slowly stretch, and the shoulder joint can be better subjected to rehabilitation treatment.

[0006] Conventionally, many devices disclose bionic shoulder joint movement rehabilitation training apparatuses, but these devices fail to support users through various rehabilitation phases, detect inflammation or muscle strain, provide appropriate heat or cold therapy, and continuously monitor the user’s posture, offering real-time visual cues for posture correction or issuing alerts for improper exercise techniques, limiting their effectiveness in delivering a comprehensive, adaptive, and personalized rehabilitation experience.

[0007] To overcome the aforementioned drawbacks, there is a need to develop a device that requires to support users in shoulder rehabilitation through various phases, including detecting inflammation or muscle strain, providing targeted heat or cold therapy, and continuously monitoring the user’s posture, offering real-time visual cues for posture correction and issuing alerts for improper exercise techniques, thereby ensuring a comprehensive, adaptive, and effective rehabilitation process that enhances recovery and prevents further injury or strain.

[0009] An object of the present invention is to develop a device that supports users in shoulder rehabilitation through various phases, including the acute phase, sub-acute phase, and strengthening phase, by providing customized exercises and targeted therapies to promote recovery, enhance mobility, and strengthen shoulder muscles throughout the entire rehabilitation process.

[0010] Another object of the present invention is to develop a device capable of detecting inflammation or muscle strain and providing appropriate heat or cold therapy, thereby offering targeted relief to the affected areas, effectively alleviating pain and promoting healing by addressing the detected inflammation or strain in the shoulder.

DETAILED DESCRIPTION OF THE INVENTION

[0018] The following description includes the preferred best mode of one embodiment of the present invention. It will be clear from this description of the invention that the invention is not limited to these illustrated embodiments but that the invention also includes a variety of modifications and embodiments thereto. Therefore, the present description should be seen as illustrative and not limiting.

[0019] In any embodiment described herein, the open-ended terms "comprising," "comprises,” and the like (which are synonymous with "including," "having” and "characterized by") may be replaced by the respective partially closed phrases "consisting essentially of," consists essentially of," and the like or the respective closed phrases "consisting of," "consists of, the like.

[0020] As used herein, the singular forms “a,” “an,” and “the” designate both the singular and the plural, unless expressly stated to designate the singular only.

[0021] The present invention is a medical assistance rehabilitation training equipment, and more specifically a customized shoulder rehabilitation assistive device designed to support users in the shoulder rehabilitation by providing assistance through various phases, including mobility restoration, strength enhancement, and flexibility improvement, offering tailored solutions to meet individual needs and promoting effective recovery while ensuring comfort, safety, and progression throughout the rehabilitation process.

[0022] Referring to Figure 1, a perspective view of a customized shoulder rehabilitation assistive device illustrated, comprising a L-shaped body 101 constructed with a seating unit 102, a backrest 103 and a support 104, a touch interactive display panel 105 mounted on the body 101, multiple hinge joint 106 integrated between the backrest 103 and seating unit 102, a fingerprint scanner 107 installed on the body 101, a speaker 108 installed on the body 101, a holographic projection unit 109 mounted on the body 101, a pair of curved armrests 110 extended from lateral sides of the backrest 103 having multiple inflatable members 111.

[0023] Figure 1 further illustrates a C-shaped handle 112 at proximal ends of the armrests 110 by means of a rotating unit 113, a resistive band 114 provided with the armrests 110 having a D-shaped handle 115, a thermal imaging module 116 arranged on the body 101, an electronically controlled nozzle 117 disposed with the backrest 103 with a vessel 118 through a conduit, an artificial intelligence-based imaging unit 119 mounted on the body 101, a pair of hollow U-shaped members 120 attached with a top lateral portion of the backrest 103, each via a motorized hinge, a Peltier unit 121 integrated in the members 120.

[0024] The device proposed herein includes a L-shaped body 101 developed to be positioned on a fixed surface to enable a user to get accommodated in view of rehabilitation of shoulder. The L-shaped body 101 as mentioned herein functions as the structural foundation for the device's components, incorporating a seating unit 102, backrest 103, and support 104, and is constructed from materials such as stainless steel, ensuring both durability and a lightweight design, while providing a generous size that supports comfort and functionality for the user.

[0025] In order to activate functioning of the device, a user is required to manually switch on the device by pressing a button positioned on the body 101, wherein the button used herein is a push button. Upon pressing of the button, the circuits get closed allowing conduction of electricity that leads to activation of the device and vice versa.

[0026] Upon activation of the device by the user, an inbuilt microcontroller embedded within the body and linked to the switch generates a command to activate a touch interactive display panel 105 mounted on the body 101 for enabling the user to provide input for adjusting angle of the body 101. The touch interactive display panel 105 as mentioned herein is typically an (Liquid Crystal Display) screen that presents output in a visible form. The screen is equipped with touch-sensitive technology, allowing the user to interact directly with the display using their fingers. A touch controller IC (Integrated Circuit) is responsible for processing the analog signals generated when the user inputs details regarding adjusting angle of the body 101. The touch controller is typically connected to the microcontroller through various interfaces which may include but are not limited to SPI (Serial Peripheral Interface) or I2C (Inter-Integrated Circuit).

[0027] In response to user input commands, the microcontroller controls multiple hinge joint 106 integrated between the backrest 103 and seating unit 102, enabling converging or diverging movement to adjust the angle, allowing the user to comfortably accommodate on the body 101. The motorized hinge joint 106 comprises of a pair of leaf that is screwed with the surfaces of the backrest 103 and seating unit 102. The leaf is connected with each other by means of a cylindrical member integrated with a shaft coupled with a DC (Direct Current) motor to provide required movement to the hinge. The rotation of the shaft in clockwise and anti-clockwise aids in opening and closing of the hinge respectively. Hence the microcontroller actuates the hinge joint 106 that in turn provides movement to the backrest 103 for enabling converging or diverging movement to adjust the angle, allowing the user to comfortably accommodate on the body 101.

[0028] The lateral sides of the backrest 103 are equipped with a pair of curved armrests 110 with a C-shaped handle 112, offering stable arm support to the user during the rehabilitation process, enhancing comfort and promoting proper posture while ensuring the user’s stability and support throughout the treatment.

[0029] Plurality of touch sensors arranged on the armrests 110 detects contact of the user’s arms on the armrests 110. The touch sensors work by detecting the contact of the user’s arms on the armrests 110 through capacitive or resistive sensing technology, which responds to the pressure or proximity of the user’s skin. When the user places their arms on the armrests 110, the sensors register the contact and send this information to the microcontroller.

[0030] This data is the processes by the microcontroller to monitor contact of the user’s arms on the armrests 110, activating multiple inflatable members 111 installed on the armrests 110 to get inflated to provide a comfortable and supportive experience during the rehabilitation process. The inflatable members 111 mention above, operates by utilizing an air compressor which works by drawing air in and then compressing the air to increase the pressure. The air compressor used herein consists of an impeller that is configured with a motor and linked with the microcontroller. The mechanical energy from the motor is used to transfer air from surrounding to the inflatable members 111. The inflatable members 111 are laminated of multiple thin polymeric films, when air is inserted in the inflatable members 111 by means of air compressor, the films are puffed and the members 111 becomes soft and that provides the comfort to the user. On actuation of the motor, the impeller rotates to suck the surrounding air and directs high speed compressed air within the inflatable members 111 to inflate the members 111 for providing a comfortable and supportive experience, enhancing arm support and overall comfort for the user during the rehabilitation process.

[0031] The body 101 is installed with a fingerprint scanner 107 installed on the body 101 and activated by the microcontroller for enabling the user for authentication. The fingerprint scanner 107 works on the principle of processing which includes two elements like enrolment and matching. In enrolment, the user has to put the finger on the scanner 107, so that the scanner 107 checks the fingerprints to process and generate the finger pattern and it will be stored. In matching, once the user places the finger then the sensor will generate a pattern of the finger and sends the acquired data to the microcontroller. The microcontroller then compares the data with a stored pre-fed data from a linked database server to compare the imprinted fingerprints with the stored authenticated ones, thereby verifying the user’s identity.

[0032] Upon successful user authentication, the microcontroller activates a speaker 108 installed on the body 101 to provide audio guidance for inputting login credentials on the display panel 105. The speaker 108 works by receiving signals from the microcontroller, converting them into sound waves through a diaphragm’s vibration, and producing audible sounds with the help of amplification and control circuitry in order to notify the provide audio guidance for inputting login credentials on the display panel 105.

[0033] In response to user input commands, the microcontroller accesses the user’s profiles stored on the database server to retrieve and update the user’s rehabilitation phases, ensuring personalized support and progress tracking; these phases are continuously updated with medical information provided by the user, allowing the microcontroller to regulate the device’s further operation and adapt it accordingly to facilitate the user’s ongoing rehabilitation process with accurate and up-to-date data.

[0034] Based on the fetched rehabilitation phases for treatment of the user, the microcontroller activates a holographic projection unit 109 mounted on the body 101 for providing step-by-step guidance to the user for performing the projected exercises. The holographic projection unit 109 works by creating and projecting holograms, which are three dimensional images formed by the interference of light waves. Firstly, the laser light from the holographic projection unit 109 is split into two beams, the object beam which interacts with the user and light waves are altered based on shape and features of the user and the reference beam which remains unchanged. The altered object beam and the reference beam intersect to create an interference pattern. This pattern is reordered on a photosensitive surface such as a holographic plate. The interference pattern contains information about the phase and amplitude of the light waves preserving the three-dimensional details of the user during projection, a laser beam is directed onto the recorded interference pattern diffracting the laser light, reconstructing the original wavefronts from the user and the reference beams. The reconstructed wavefronts create a three-dimensional image that appears to float in space for providing step-by-step guidance to the user for performing the projected exercises.

[0035] The microcontroller then activates a rotating unit 113 installed with distal ends of the armrests 110 for adjusting orientation of the armrests 110 according to the user’s specific exercise requirements. The rotating unit 113 provides a rotation to the armrests 110 for aiding the armrests 110 to turn at a required angle. The rotating unit 113 is a coupling consisting of a ball joint securely locked within a socket joint, where the ball joint is able to move in a 360-dgree rotation within the socket thus, providing the required rotational motion to the armrests 110. The rotating unit 113 is powered by a DC (direct current) motor that is actuated by the microcontroller thus providing multidirectional movement to the armrests 110 for adjusting orientation of the armrests 110 according to the user’s specific exercise requirements.

[0036] The user is required to grip a D-shaped handle 115 attached to the armrests 110, using a resistive band 114, to perform exercises as projected through the holographic projection unit 109, guiding the user through each movement and providing visual instructions to guide the user through different phases of shoulder rehabilitation, including an acute phase, a sub-acute phase, and a strengthening phase, thereby enabling a structured and interactive rehabilitation experience to enhance the user’s progress and engagement in the exercise routine.

[0037] A thermal imaging module 116 arranged on the body 101 monitors temperature changes around shoulder area of the user. The thermal imaging module 116 works by capturing infrared radiation emitted from the shoulder area of the user, creating a thermal image that detects temperature variations. As the user moves or engages in the exercises, the thermal imaging module 116 continuously monitors these changes, identifying areas of increased or decreased temperature that may indicate inflammation, strain, or muscle tension. The collected data is processed by the microcontroller and analyzed to identify abnormal heat patterns for detecting inflammation or muscle strain.

[0038] A capacitive sensor installed on the members 111 detects contact of skin with the members 111. The capacitive sensor works by detecting changes in the electrical field caused by the presence of a conductive object, such as the user's skin, when it comes into contact with the sensor's surface. The sensor emits a small electrical charge and measures the variations in capacitance when the skin interacts with the sensor, allowing it to detect touch or proximity. This data is then processed by the microcontroller, which triggers an electronically controlled nozzle 117 disposed with the backrest 103 for dispensing an appropriate amount of relieving ointment stored in a vessel 118 configured with the nozzle 117, over the user’s shoulder region, through a conduit.

[0039] The electronically controlled nozzle 117 consists of a pump and a dispensing, both coordinated by the microcontroller. The pump draws gel from the vessel 118, via the conduit, while the dispensing valve controls the release on the user’s shoulder. The microcontroller adjusts the flow to dispense an appropriate amount of relieving ointment over the user’s shoulder, optimizing coverage and effectiveness for a personalized rehabilitation experience.

[0040] The body 101 is provided with an artificial intelligence-based imaging unit 119 and activated by the microcontroller to determine dimensions of shoulder portion of the user. The imaging unit 119 comprises of an image capturing arrangement including a set of lenses that captures multiple images in the surroundings, and the captured images are stored within memory of the imaging unit 119 in form of an optical data. The imaging unit 119 also comprises of a processor that is integrated with artificial intelligence protocols, such that the processor processes the optical data and extracts the required data from the captured images. The extracted data is further converted into digital pulses and bits and are further transmitted to the microcontroller. The microcontroller processes the received data and determines dimensions of shoulder portion of the user.

[0041] In accordance to the determined dimensions of shoulder portion of the user, the microcontroller actuates a motorized hinge integrated in between a pair of hollow U-shaped members 120 attached with a top lateral portion of the backrest 103 to provide clamping movement to the members 120 for grasping the user’s shoulder. The motorized hinge operates in the same manner as the hinge joint 106 and is regulated by the microcontroller to provide clamping movement to the members 120 for grasping the user’s shoulder.

[0042] Upon appropriate grasping of the user’s shoulder, the microcontroller activates a Peltier unit 121 integrated into the members 120 for providing an optimal heating or cooling effect to the gel, stored in the members 120. The Peltier unit 121 works by transferring heat from one side of the unit to the other when electrical current is applied to provide precise control over the heating or cooling effect applied to the gel. The Peltier unit 121 absorbs heat from one side and dissipates the heat through the other, either cooling or heating the gel in a controlled manner. The direction of the current is adjusted by the microcontroller to ensure that the desired effect—either heat or cold— is achieved based on the user's needs, which is monitored by the temperature sensor.

[0043] The temperature sensor mentioned herein is an infrared (IR) based temperature sensor that operates by detecting infrared radiation emitted by the gel. The sensor includes an IR detector that receives radiation from the gel and converts the radiation into an electrical signal. This signal's intensity correlates with the temperature of the gel, as hotter the gel emits more IR radiation, which is then sent to the microcontroller in the form of an electrical signal. The microcontroller processes the signal to determine temperature of the gel, for enabling the microcontroller to regulate activate of the Peltier unit 121 to provide targeted heat or cold therapy to relieve inflammation, muscle strain, and pain. Heat therapy promotes blood circulation and alleviates muscle stiffness, while cold therapy reduces swelling and numbs pain, delivering an enhanced rehabilitation experience for the user.

[0044] If the detected heat patterns indicate potential abnormalities, the microcontroller triggers a wireless notification through a communication module to a linked computing unit, which then notifies the concerned medical authority about the user's condition. This allows the medical team to receive real-time alerts about any irregularities in the user's health, enabling timely intervention and ensuring that appropriate actions are taken to address any potential issues related to inflammation or other health concerns.

[0045] A tachometer coupled with a pressure sensor, installed on the body 101 monitors movement of the user’s shoulders. The tachometer coupled with a pressure sensor for monitoring the movement of a user's shoulders works by integrating two distinct types of measurements: rotational speed and force exerted. The tachometer, typically used to measure the rotational speed of a shaft or mechanical unit, can be adapted to track the angular velocity of the user's shoulder movement. As the user moves their arms or shoulders, the tachometer senses changes in the speed of this motion, providing the microcontroller with real-time data about the frequency and intensity of the movement.

[0046] The pressure sensor, on the other hand, detects the force applied on the skin or muscles around the shoulder area. By measuring the changes in pressure as the shoulder moves, the pressure sensor infers the level of muscle engagement or strain. This combination of data from both tachometer and the pressure sensor allow the microcontroller for a comprehensive monitoring of the user's shoulder dynamics, such as detecting overexertion, incorrect posture, or abnormal movement patterns, enabling a more accurate assessment of physical performance and health, potentially offering valuable insights for rehabilitation of the user.

[0047] The Peltier unit 121 consists of two semiconductor plates, known as Peltier plates, connected in series and sandwiched between two ceramic plates. When an electric current is applied to the Peltier unit 121, one side of the unit absorbs heat from its surroundings, while the other side releases heat, thereby providing an optimal heating or cooling effect to the gel, enhancing heat or cold therapy to relieve inflammation, muscle strain, and soothe shoulder pain effectively.

[0048] The microcontroller, mentioned herein is an Arduino microcontroller. The Arduino microcontroller is an open-source programming platform, controls the overall functionality of all connected components, receiving data from various electronic units and generating command signals for further processing and is encrypted with machine learning protocols to analyze the user's exercise performance over time, tracking key metrics such as speed, range of motion, and effort. Based on this collected data, the microcontroller adjusts future exercise recommendations, optimizing the rehabilitation process by providing personalized feedback and ensuring the exercises remain effective and tailored to the user's progress and specific needs.

[0049] The microcontroller via the imaging unit 119 continuously monitors the user’s posture and accordingly activates a set of LEDs (Light Emitting Diode) attached to the armrests 110 to provide visual cues to the user regarding posture correction, or an alert in case of improper exercise technique. The LED is a two-lead semiconductor light source also known as p-n junction which produce the lighting when constant voltage is supplied across the diode. When the voltage is supplied across the diode, the electrons recombine with the electrons hole in the diode which result in conversion of electron into photons which is another form of light, providing visual cues to the user regarding posture correction, or an alert in case of improper exercise technique.

[0050] Lastly, a battery is installed within the device which is connected to the microcontroller that supplies current to all the electrically powered components that needs an amount of electric power to perform their functions and operation in an efficient manner. The battery utilized here, is preferably a dry battery which is made up of Lithium-ion material that gives the device a long-lasting as well as an efficient DC (Direct Current) current which helps every component to function properly in an efficient manner. As the device is battery operated and do not need any electrical voltage for functioning. Hence the presence of battery leads to the portability of the device i.e., user is able to place as well as moves the device from one place to another as per the requirements.
