Description:FIELD OF THE INVENTION

[0001] The present invention relates to a hamstring injury rehabilitation device that is accessed by a user for relieving muscular pain and swelling in the hamstring region through application of automated therapeutic actions in accordance with user’s leg condition, thereby enabling faster recovery and improved mobility.

BACKGROUND OF THE INVENTION

[0002] Hamstring injuries are among the most common types of muscle injuries, especially in individuals involved in high-intensity physical activities or sports. Such injuries often lead to sharp pain, inflammation, and restricted movement, requiring a combination of rest, physiotherapy, and therapeutic interventions for recovery. Conventionally, treatment includes physical therapy sessions, hot/cold compresses, manual massages, and use of external supports. However, in many cases, patients lack access to consistent therapy, especially in remote or home-based recovery settings, leading to delayed healing, chronic pain, or reinjury due to lack of proper monitoring and guided rehabilitation.

[0003] Furthermore, conventional rehabilitation devices do not dynamically respond to changes in the user’s condition. They often rely on manual operation or periodic visits to therapists, resulting in gaps in monitoring critical muscular or vascular conditions. During the recovery period, lack of real-time feedback and improper application of therapy methods can lead to increased swelling, reduced mobility, and long-term muscular damage. In addition, improper posture or incorrect therapeutic exercises performed without supervision can worsen the injury or hinder recovery.

[0004] In many cases, patients recovering at home do not have access to professional guidance for applying compression, administering topical medication, or performing controlled thermal therapy, which are essential for targeted hamstring treatment. Moreover, absence of interactive instructions or data-driven recovery tracking leads to unstructured therapy sessions and inefficient outcomes. Therefore, there is a substantial need for a smart, responsive rehabilitation system that not only monitors the injury in real-time but also delivers timely and automated therapeutic actions tailored to the user’s condition.

[0005] US20200046571A1 discloses various implementations include an assistive hamstring device including a belt, knee sleeve, first elastic strap, second elastic strap, and third elastic strap. The first elastic strap extends between a first dorsal belt portion of the belt located adjacent a sagittal plane on a dorsal side of the person and a lateral knee portion of the knee sleeve located adjacent a lateral side of the knee. The second elastic strap extends between a side belt portion of the belt located adjacent a coronal plane of the person and a medial knee portion of the knee sleeve located adjacent a medial side of the knee. The third elastic strap extends between a second dorsal belt portion of the belt located between the first and side belt portion and an intermediate dorsal knee portion of the knee sleeve located between the lateral and medial knee portion, along the dorsal portion of the knee.

[0006] US20150196789A1 discloses the Hamstrong Prosthetic Hamstring/Post Chain Brace is a device that has been invented to assist in the rehabilitation process of a variety of sports/work related injuries, and to aid in sports performance. It consists of a heavy-duty belt to be worn above the pelvis, a sturdy buckling system that attaches on the calf muscles and below the knee, and a latex band system that connects to the two points. This system acts as a prosthetic hamstrings muscle group; it pulls against anterior pelvic tilt, and serves as a prevention/rehabilitation tool. The device has adjustable tension by changing either the band resistance or replacing the band. Low Back muscles, hip flexors, and abdominals are also stimulated while wearing the device. The Hamstrong addresses postural alignment, and can strengthen the hamstrings, muscles in the groin, and hip flexors simultaneously. The device is university proven to be effective.

[0007] As per the discussions in above-mentioned prior arts, various therapy tools and devices exist to assist with muscular recovery, but these tools and devices often lack in providing adaptive therapy or ensuring real-time posture correction during physical activity. Additionally, these tools and devices also fail to prioritize user safety and recovery efficiency through dynamic monitoring of the affected area and lack integration of thermal, compression, and medicinal delivery.

[0008] In order to overcome the aforementioned drawbacks, there exists a need in the art to develop a device that requires to be capable of providing real-time physiological monitoring, personalized therapeutic response, posture correction feedback, and medicine delivery to ensure safe, efficient, and complete recovery from hamstring injuries in both clinical and home environments.

DETAILED DESCRIPTION OF THE INVENTION

[0022] 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. While the invention is susceptible to various modifications and alternative constructions, it should be understood, that there is no intention to limit the invention to the specific form disclosed, but, on the contrary, the invention is to cover all modifications, alternative constructions, and equivalents falling within the spirit and scope of the invention as defined in the claims.

[0023] 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.

[0024] 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.

[0025] The present invention relates to a hamstring injury rehabilitation device that is accessed by a user for detecting abnormal muscular and vascular conditions in the leg region. In addition, the device provides real-time localized therapeutic actions including compression, massage, thermal regulation, and medicinal application, along with guiding the user during rehabilitation sessions to avoid incorrect postures, thereby ensuring effective and safe recovery of the hamstring muscle.

[0026] Referring to Figure 1 and 2, an isometric view of a hamstring injury rehabilitation device and internal view of the device are illustrated, respectively, comprising a wearable body 101, a pair of straps 102 are attached with the body 101, a pair of motorized rollers 103 provided with the body 101 and coiled with the straps 102, plurality of vertically arranged strip 201 located at the inner periphery of the body 101, each strip 201 fabricated with a set of cushion patches 202, connected to an air inflating unit 104 provided on the body 101, an inner fabric layer 203 forming an intermediate compartment within the body 101, housing a plurality of gel patches 204 strategically, a plurality of inflatable members 105 positioned along outer periphery of the back side of the body 101, via conduits 106.

[0027] Figure 1 and 2 further illustrates a holographic projection unit 107 mounted on outer periphery of the body 101, a speaker 108 provided on the body 101, a pair of motorized vertical sliders 205 positioned along the inner periphery of the body 101, having a motorized circular slider 206 mounted thereon and a horizontal linkage 207, a motorized roller 208 is attached with the circular slider 206, plurality of medicine chambers 109 disposed along the outer periphery of the body 101, a plurality of individual conduits 110 is connected to the chambers 109 and plurality of pneumatic pins 111 are arranged internally between the outer and inner layer 203.

[0028] The device disclosed herein comprises a wearable body 101, which serves as a mains structure of the device and is configured to cover upper knee and leg portion of a user. The body 101 is anatomically contoured to conform to the user's leg, ensuring a secure and comfortable fit during use. The body 101 is constructed from durable and flexible materials and is designed for prolonged wear, accommodating various leg sizes and shapes, wherein a pair of straps 102 are integrally attached to the body 101, positioned such that they wrapped around the user's leg to hold the device firmly in place. The straps 102 are adjustable and assist in securing the device around the leg portion, enabling effective therapy delivery without slippage during movement or physical activity.

[0029] Multiple pressure sensors are installed on both the body 101 and the straps 102, with each sensor strategically positioned to detect the amount of pressure applied by the body 101 and the straps 102 on the leg portion of the user. The pressure sensor contains a piezoelectric material, which generates a voltage in response to mechanical stress. When a pressure is applied by the body 101 and straps 102 on the leg portion, it deforms the piezoelectric material. The pressure applied by the body 101 and straps 102 on the leg portion, causes the material to deform, creating a strain. This strain results in the generation of an electric charge across the material, producing a voltage signal proportional to the applied pressure. The generated voltage is typically very small so the signal is amplified to make it suitable for further processing.

[0030] These sensors continuously relay pressure data to an inbuilt microcontroller, which processes the readings in real-time. Based on the detected pressure values, the microcontroller actuates a pair of motorized rollers 103 that are provided with the body 101 and coiled with the straps 102. These motorized rollers 103 are configured to rotate on their axis, thereby tightening or loosening the straps 102 dynamically. The motorized rollers 103 are a mechanical unit designed to rotate on its axis with the help of an integrated electric motor.

[0031] The rollers 103 tube serves as a surface for supporting, and tightening or loosening the straps 102. The motorized rollers 103 are equipped with an electric motor that provides the rotational power necessary to turn the rollers 103. The motor is connected to the rollers 103 tube through a drive arrangement, which involves gears, belts to transfer the motor’s rotational force to the rollers 103, causing it to spin and tighten or loosen the straps 102, which ensures a customized and secure fit, automatically adapting the tightness of the device to the user's leg for optimal therapeutic effect.

[0032] An electromyography (EMG) sensor is integrated along the inner periphery of the body 101 to continuously monitor the condition of veins within the user’s leg. The electromyography (EMG) sensor is capable of detecting abnormalities and deviations in vascular activity, including signs of inflammation or impaired blood flow. The electromyography (EMG) sensors work by detecting the electrical activity generated by muscles during movement or contraction, which is then amplified and displayed as a graph or image.

[0033] A plurality of vertically arranged strips is located along the inner periphery of the body 101, each strip 201 fabricated with a set of cushion patches 202. These cushion patches 202 are in pneumatic connection with an air inflating unit 104 provided on the body 101. Upon receiving abnormality data from the EMG sensor, the microcontroller actuates the inflating unit 104 to selectively inflate and deflate the patches 202 in a synchronized manner. This creates localized compression over affected areas, reducing swelling and improving vascular function in the hamstring region.

[0034] The inflating unit 104 comprises of an air compressor which extracts the air from surrounding and increases the pressure of the air by reducing the volume of the air and which is further injected in the patches 202. Further, the patches 202 are laminated of multiple thin polymeric films, when air is inserted in the inflatable member 105 by means of air compressor, the films are puffed and the patches 202 becomes soft and that provides the comfort to the user.

[0035] The body 101 features an inner fabric layer 203 that forms an intermediate compartment housing a plurality of gel patches 204. These gel patches 204 are strategically positioned to correspond to the anatomical location of the user’s hamstring region. A Peltier unit is operably connected to the gel patches 204 via thermoelectric pipes, enabling the selective conduction of heating or cooling. The Peltier unit is configured for bi-directional thermal regulation and is capable of delivering either heat or cold therapy based on input from sensors monitoring the user's condition.

[0036] The Peltier unit is a thermoelectric cooler that uses the Peltier effect to transfer heat from one side of the unit to the other when an electrical current is passed. The Peltier unit consists of two semiconductor materials connected in a sandwich-like fashion. These materials are typically made of bismuth telluride and one side of the Peltier unit is called the hot side and the other is the cold side. When a direct current is applied to the Peltier unit, electrodes within the semiconductor material start moving from one side to the other.

[0037] The Peltier effect occurs as a result of electron movement. When electrons flow from the cold side to the hot side, they carry heat with them. This leads to one side of the Peltier unit becoming colder, and the other side becoming hooter. This effect allows the Peltier unit to effectively transfer heat from one side to the other, creating a temperature gradient, which enables precise control of temperature at the injury site, thereby promoting relaxation of muscle fibers, reduction of inflammation, and enhanced pain relief.

[0038] A plurality of inflatable members 105 is positioned along the outer periphery of the back side of the body 101. These members 105 are configured to come into contact with the ground surface when the user assumes a seated position. The air inflating unit 104 is operatively connected to these inflatable members 105 via conduits 106, allowing it to control their inflation. When inflated, the members 105 gently elevate the injured leg portion above heart level, promoting venous return and reducing swelling in the hamstring area. This passive elevation function is particularly beneficial during periods of rest, enhancing circulation without requiring external support structures.

[0039] A holographic projection unit 107 is mounted on the outer periphery of the body 101, configured to display interactive and real-time visual instructions to the user, which guides the user through therapeutic exercises and provide biofeedback-based instructions. On actuation of holographic projection unit 107 by the microcontroller, the light source emits various combination of lights towards the lens which is further portrayed in front of the user to guide the user through therapeutic exercises and provide biofeedback-based instructions.

[0040] In conjunction, a gyroscope is embedded in the body 101 to detect the user’s movement and posture during physical activity and therapeutic sessions. The gyroscope uses the principle of angular momentum to maintain its orientation in space. It consists of a spinning wheel or rotor that resists changes in its orientation during motion of the user. The gyroscope continuously monitors the user’s orientation. Any deviation from this reference indicates a potential misbalance of the user.

[0041] If an incorrect or injury-aggravating posture is detected, the microcontroller processes the gyroscopic data and activates a speaker 108 provided on the body 101. The speaker 108 then delivers real-time audio instructions to correct the user’s posture or movements, thereby ensuring safe and effective rehabilitation exercises. The speaker 108 is capable of producing clear and natural sound and is capable of adjusting its volume based on ambient noise levels. The speaker 108 consists of audio information, which is in the form of recorded voice, synthesized voice, or other sounds, generated or stored as digital data.

[0042] This data is often in the form of an audio file. The digital audio data is sent to a digital-to-analog converter (DAC). The DAC converts the digital data into analog electrical signals. The analog signal is often weak and needs to be amplified. An amplifier boosts the strength to a level so that the speaker 108 drives it effectively. The amplified audio signal is then sent to the speaker 108. The core of the speaker 108 is an electromagnet attached to a flexible cone. These sound waves travel through the air as pressure waves and are picked by the user’s ear to alert them correct their posture or movements.

[0043] A pair of motorized vertical sliders 205 are positioned along the inner periphery of the body 101. Each slider is fitted with a motorized circular slider 206 mounted thereon, and a horizontal linkage 207 extends between each circular slider 206. The vertical sliders 205 consist of a motor, and a rail unit integrated with ball bearings to allow smooth linear movement. As the motor rotates the rotational motion of the motor is converted into linear motion through a pair of belts and linkages. This linear motion provides a stable track and allows the circular slider 206 to move.

[0044] Followed by actuation of a motorized roller 208, which is attached to the circular slider 206, and this entire assembly is dynamically controlled by the microcontroller. The motorized roller 208 are capable of moving smoothly over the surface of the user’s leg along predefined paths, delivering a targeted massage directly to the affected hamstring area. The coordinated movement of the sliders and roller 208 helps reduce muscular pain and swelling, supporting recovery through enhanced circulation and mechanical stimulation.

[0045] A plurality of medicine chambers 109 is disposed along the outer periphery of the body 101. Each of these chambers 109 is pre-filled with medicinal compounds that are formulated to treat muscle pain, inflammation, or vascular irregularities. A plurality of individual conduits 110 extends from the chambers 109 and merges into a single unified delivery conduit arranged along the inner periphery of the body 101, which enables controlled and targeted topical application of the medicinal compounds onto the muscular and vascular tissues of the user’s leg. The medicine delivery is automated and managed by the microcontroller to ensure accurate dosage and timing in synchronization with other therapeutic modalities.

[0046] A plurality of vibrating units is arranged on the inner surface of the body 101. These vibrating units are electronically controlled to generate localized vibrations that provide a massage sensation focused on reducing hamstring pain. The vibrations stimulate muscle fibers and surrounding tissues, promoting relaxation and reducing soreness. The intensity and duration of vibration is adjusted based on the user’s needs or the rehabilitation protocol prescribed by healthcare professionals.

[0047] A plurality of pneumatic pins 111 are arranged internally between the outer and inner layer 203 of the body 101. These pins 111 are selectively inflatable upon command from the microcontroller. When the microcontroller detects insufficient relief from conventional massage techniques, the pneumatic pins 111 are activated to deliver focused pinpoint massage directly to the affected hamstring area. The pins 111 as mentioned herein are powered by a pneumatic unit that utilizes compressed air to extend and retract the pins 111. The process begins with an air compressor which compresses atmospheric air to a higher pressure.

[0048] The air cylinder of the pneumatic unit contains a piston that moves back and forth within the cylinder. The cylinder is connected to one end of the pins 111. The piston is attached to the pins 111 and its movement is controlled by the flow of compressed air. To extend the pins 111 the piston activates the air valve to allow compressed air to flow into the chamber 109 behind the piston. As the pressure increases in the chamber, the piston pushes the pins 111 to the desired length, which applies localized pressure to specific muscle knots or tension points, enhancing the therapeutic effect and providing deeper muscle penetration for stubborn pain areas.

[0049] The device’s therapy sequence is designed to maximize the efficacy of its various components. The pre-massage application of medicinal compounds enhances the effectiveness of the subsequent massage therapy delivered by the motorized roller 208 and the pneumatic pins 111. The medicine softens muscle tissue and reduces inflammation, facilitating improved absorption of topical agents, which helps reduce muscle tension and pain more effectively than either modality used alone, thereby accelerating the user’s recovery and enabling more comprehensive therapeutic results.

[0050] Additionally, an angle sensor is integrated with the body 101 to detect and measure the range of motion of the user's leg. The angle sensor provides precise data about leg extension, flexion, and angular displacement during rehabilitation exercises. In an embodiment of the present invention, the angle sensor used herein is preferably an optical angle sensor that use light beams and optical detectors to measure changes in light reflection or transmission caused by the angle of the user’s leg. As the angle changes, the amount of light reflected or transmitted varies, allowing the sensor to calculate the angle. The angle sensor provides an output signal to the microcontroller that represents the detected level of improvement or relief after each session.

[0051] The microcontroller stores this data in an integrated database, allowing both the user and healthcare personnel to access and analyze progress over time. The information supports assessment of gait patterns, rehabilitation milestones, and muscle recovery progress, enabling data-driven decisions for therapy modification and improved treatment outcomes.

[0052] Lastly, a battery is associated with the device to supply power to electrically powered components which are employed herein. The battery is comprised of a pair of electrode named as a cathode and an anode. The battery uses a chemical reaction of oxidation/reduction to do work on charge and produce a voltage between their anode and cathode and thus produces electrical energy that is used to do work in the device.

[0053] The present invention works best in the following manner, when the user wears the wearable body 101, it is secured around the upper knee and leg portion using the pair of straps 102. The pressure sensors embedded on the body 101 and straps 102 detect the pressure being applied to the leg. Based on this input, the microcontroller actuates the pair of motorized rollers 103 coiled with the straps 102 to rotate and adjust the fit, ensuring optimal compression and positioning. Simultaneously, the electromyography (EMG) sensor integrated along the inner periphery of the body 101 continuously monitors vein conditions and detects any vascular abnormalities. If abnormalities are detected, the microcontroller activates the air inflating unit 104 to inflate and deflate cushion patches 202 on vertically arranged strips, providing localized compression to reduce swelling in the affected area. Inside the body 101, the inner fabric layer 203 houses gel patches 204 positioned around the hamstring. These are connected to the Peltier unit via thermoelectric pipes, enabling precise heating or cooling of the region based on sensor data. To further aid recovery when the user is seated, inflatable members 105 on the back of the body 101 make contact with the ground and are inflated by the air inflating unit 104, elevating the leg to improve blood flow and minimize swelling.

[0054] In continuation, the holographic projection unit 107 displays real-time rehabilitation instructions. the gyroscope tracks user posture and movement, and if any incorrect or harmful posture is detected, the microcontroller triggers the speaker 108 to issue corrective audio instructions. For therapeutic massage, the pair of motorized vertical sliders 205 along with the motorized circular slider 206 and motorized roller 208 are controlled by the microcontroller to glide over the injury site, delivering pain-relieving massage to the hamstring area. In addition, medicine chambers 109 on the body 101 release medicinal compounds through the unified delivery conduit to apply topically on the affected muscles and veins. The vibrating units for additional massage sensation, pneumatic pins 111 that inflate on command to deliver pinpoint pressure when more intense therapy is required, and the angle sensor that records leg movement range. All data is stored in the database for access by users and healthcare professionals.
