Description:FIELD OF THE INVENTION

[0001] The present invention relates to a wearable maternity support assistive device for prenatal care and maternal-foetal monitoring that automatically adjusts to meet the changing physical needs of a pregnant user during various stages of pregnancy. In addition, the device disclosed herein aims to ensure ease in mobility, posture, and overall well-being of maternal and foetus through continuous monitoring and responsive adjustment based on the user’s condition.

BACKGROUND OF THE INVENTION

[0002] During pregnancy, women undergo significant physiological and biomechanical changes that lead to discomfort, reduced mobility, and increased health risks for both mother and fetus. Prenatal care requires continuous monitoring of maternal and fetal health parameters to detect potential complications early. However, traditional clinical visits do not offer real-time monitoring or personalized physical support. Pregnant users often face challenges such as back pain, postural instability, fatigue, and anxiety about fetal well-being. Lack of proper support during movement or prolonged standing exacerbate these issues. There is a growing need for a wearable maternity support assistive device that not only provides physical assistance and comfort but also enables continuous, non-invasive health monitoring to enhance maternal and fetal safety during pregnancy.

[0003] Several wearable maternity support devices are currently available, such as maternity belts, belly bands, and posture correctors, which aim to reduce discomfort and provide basic abdominal and back support. Some smart wearables also offer limited maternal or fetal monitoring, like heart rate or contraction tracking. However, these devices often lack integrated functionality, offering either support or monitoring, but not both. They typically require manual adjustments and do not adapt dynamically to the user's changing body or movement. Furthermore, many lack real-time data processing, personalized health insights, or automated alerts for potential risks. These limitations reduce their effectiveness in addressing the comprehensive needs of prenatal care, especially in providing continuous support and proactive health management for both mother and fetus.

[0004] US20100201526A1 discloses an apparatus ensuring that an expecting mother does not lie on her back by alerting an expecting mother upon such an event. An adjustable and flexible belt is provided which includes one or more sensors positioned at or near the center of the belt to determine when an expecting woman wearing the belt is sleeping on her back and an alarm that is activated by the sensor to alert a sleeping mother when she is lying on her back.

[0005] US20210205113A1 is a shaped seamless maternity waist-belly support belt which is formed by a circular knitting machine knitting yarns made from textile materials such as nylon and spandex and is seamless and barrel-shaped, which is characterized in that: the support belt comprises a plurality of portions, and these portions are located at different parts of the support belt and have respective specially-designed knit structures. The present disclosure further provides a garment including the shaped seamless waist-belly support belt attached to a waistband of a bottom garment. The waist-belly support belt according to the present disclosure is seamless and barrel-shaped, without seams and without concavity or convexity in an outer surface or an inner surface, and provides high comfort. Meanwhile, since the waist-belly support belt has different knit structures at different parts to suit the growing belly shape, it can provide support for the pregnant woman's waist and back and reduce pelvic pains.

[0006] Conventionally, many devices are available in the for supporting belly weight during pregnancy. However, the cited inventions lack to monitor health parameters of the user and the fetus, also require manual intervention for adjusting according to the need of the user. In addition, the cited invention lacks to provide healthcare guidance to promote maternal and fetus wellbeing.

[0007] In order to overcome the aforementioned drawbacks, there exists a need in the art to develop a device that is required to be capable of monitoring the health parameters of the user and the fetus, should also be capable of automatically adjusting based on the needs and body dimensions of the user. Additionally, the developed device should also be capable of providing healthcare guidance for maternal and fetus wellbeing.

[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 relates to a wearable maternity support assistive device for prenatal care and maternal-foetal monitoring that monitors the health and physical activity of both the pregnant user and the fetus. In addition, the device disclosed herein continuously analyzes vital signs and movement patterns, and generates alerts when any abnormal conditions or potential risks are detected, allowing timely intervention to support maternal and fetal health and safety.

[0022] Referring to Figure 1 and 2, an isometric view of a wearable maternity support assistive device for prenatal care and maternal-foetal monitoring and a back view of a member associate with the device, comprising is illustrated, comprising a frame 101 constructed with a curved member 102, attached with a pair of looped straps 103, a pair of flexible belts 104 are attached across the straps 103, an artificial intelligence-based imaging unit 105 mounted on one of the straps 103, a motorized roller 106 attached with each of the straps 103, a pair of extendable legs 107 coupled with an omnidirectional wheel 108, a health monitoring module 109 installed on one of the belt 104, a clamshell assembly 110 integrated within frontal arc of the member 102, a plurality of curved winches 201 coiled with an inflatable membrane 202, a holographic projection unit 111 mounted on the member 102, a plurality of motorized iris operated lids 112 installed on the straps 103, each housed with an electronic sprayer 113 and a vessel 114 configured with the sprayer 113.

[0023] The device disclosed in the present invention comprises of a frame 101 constructed with a curved structural member 102 developed to contour around the upper back and shoulders of a pregnant user. A pair of looped straps 103 are attached to the frame 101, each consisting of a first and second portion. These straps 103 are configured to be comfortably worn over the user's shoulders by passing through the head area, allowing the device to be securely positioned on the upper body.

[0024] A pair of flexible belts 104 are affixed across the first portions of the looped straps 103, strategically positioned to align with the user’s spinal region. These belts 104 are developed to provide gentle yet firm support to the spinal area, helping to reduce strain and promote better posture during pregnancy. The flexibility of the belts 104 ensures that they conform comfortably to the user’s back, allowing for ease of movement while maintaining consistent support, thereby enhancing comfort and reducing fatigue during daily activities.

[0025] To activate the device, the user manually presses a push button which is installed on the strap. Upon pressing the button, the circuits within the device gets close, allowing electric current to flow. The push button has an outer casing and an inner mechanism, including a spring and metal contacts. When the button is pressed, the spring-loaded mechanism inside is pushes down on. In the default state, the internal contacts are apart, so the circuit is open and no electricity flows. Pressing the button makes the contacts touch each other, closing the circuit and allowing electricity to flow, which activates an inbuilt microcontroller that regulates the further options of the device.

[0026] The microcontroller then activates an artificial intelligence-based imaging unit 105 mounted on one of the straps 103 to determine body dimensions of the user. The imaging unit 105 comprises of an image capturing arrangement including a set of lenses that captures multiple images of the user’s body and the captured images are stored within a memory of the imaging unit 105 in form of an optical data. The imaging unit 105 also comprises of the 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 determine the dimensions of the user’s body.

[0027] In accordance to the determined body dimensions of the user, the microcontroller actuates a motorized roller 106 attached with each of the straps 103, in view of tightening/loosening the straps 103 for comfortable accommodation of the frame 101 over the body of the user. The motorized roller 106 consists of a DC motor that provides the power to wind and unwind the straps 103. The straps 103 are wound around the shaft of the roller 106 that is connected to the motor through a drive link to ensure the rotation of the shaft when the motor operates. One end of the strap is fixed to the shaft, while the other end is attached to the support structure of the roller 106. The microcontroller compares the dimensions of the user’s body with the dimensions of the looped straps 103, in case, the dimensions of the straps 103 are detected more or less than the dimensions of the user’s body. The motor is actuated by the microcontroller to drive the roller 106 in a clockwise direction, the strap is winded over the roller 106 and when the roller 106 moves in an anti-clockwise direction, the straps 103 starts unwinding providing a comfortable fit to the user.

[0028] Upon securing the straps 103 over the body of the user, the microcontroller activates an infrared proximity sensor is installed on the member 102 to determine the distance between the member 102 and the ground. The infrared proximity sensor works by emitting infrared light from an IR LED toward the ground and detecting the reflected light using a photodiode or phototransistor. The infrared proximity sensor determines the distance to the ground from the member 102 by analyzing the intensity of the reflected light. Closer objects reflect more light, resulting in a stronger signal. The detected signal is then processed and converted into a distance value, which is then sent to the microcontroller for further processing.

[0029] Based on the determined distance between the ground and the member 102, the microcontroller actuates a pair of extendable legs 107 coupled with an omnidirectional wheel 108 installed on lower lateral sides of the member 102, in view of providing support during standing and ambulation. The cascading slider assembly operates through a series of nested sliders that extend and retract sequentially. When actuated by a motor, the outermost slider moves first. Upon reaching its full extension, the microcontroller triggers the next inner slider to move, continuing until all sliders are extended. Each slider travels along guided tracks with low-friction components for smooth motion. Retraction follows the reverse order, with the innermost slider retracting first. The process is often controlled limit switches to ensure proper sequencing for providing support to the user.

[0030] The infrared proximity sensor is calibrated to measure the terrain's inclination and the user's gait cycle. By detecting the angle of the surface (uphill or downhill), the sensor helps the microcontroller to adjust the leg 107 extensions and support angles accordingly. This allows the device to dynamically adapt to changes in the terrain, ensuring that the user maintains stability and comfort during movement. The sensor continuously monitors the user's stride, enabling automatic adjustments to optimize support and balance, enhancing mobility across varying inclines.

[0031] Upon extending the legs 107, the microcontroller activates a health monitoring module 109 installed on one of the belt 104 includes a PPG (photo-plethysmography) sensor, an infrared temperature sensor and Inertial measurement units (IMUs). The PPG (photo-plethysmography) sensor measure the cardiovascular parameters of the user by emitting light, usually from an LED, onto the skin, commonly at the wrist or fingertip. As blood pulses through the vessels with each heartbeat, it absorbs varying amounts of light. A photodetector measures the amount of light that is either transmitted through or reflected by the tissue. These light fluctuations are converted into electrical signals, forming a waveform known as the PPG signal. By analyzing this signal, the device determines cardiovascular parameters such as heart rate and blood oxygen saturation, the determined cardiovascular parameters are then sent to the microcontroller for further processing.

[0032] The infrared temperature sensor detects the user's body temperature by capturing the infrared radiation naturally emitted from the skin’s surface. The infrared temperature sensor includes a pyroelectric detector that absorbs this energy and converts the absorbed energy into a small voltage signal. This signal is then amplified and processed by the microcontroller. The microcontroller compensates for ambient temperature to accurately determine the actual skin temperature. The final value is then transmitted to the microcontroller for monitoring.

[0033] The Inertial measurement units (IMUs) determine the body movement and activity of the user. The IMU includes an accelerometer, gyroscopes and magnetometers. The accelerometer measures acceleration by detecting changes in motion or orientation. The accelerometer typically uses a small internal proof mass suspended by springs within a microelectromechanical system (MEMS) structure. When acceleration is applied, the mass shifts slightly, altering the distance between it and surrounding fixed electrodes. This displacement changes the capacitance between the electrodes. The sensor’s circuitry detects these changes and converts them into electrical signals. These signals are processed to determine the magnitude and direction of the acceleration. Triaxial accelerometers use three such sensing axes to measure acceleration in three dimensions X, Y, and Z.

[0034] The gyroscopes measure angular velocity, which is the rate of rotation around an axis. When used to detect the movement of the user, the gyroscopes determine the orientation and movement of the head in three-dimensional space. The gyroscopes operate based on the principles of angular momentum and rotational motion. When moves, it maintains its orientation due to inertia. The gyroscopes use this principle to detect changes in orientation.

[0035] The collective data from the health monitoring module is processed and compared by the microcontroller with a pre-saved data in a databased for analyzing the health and activity of the user, in order to, determine any potential to the maternal and fetal. In case, any potential risk is detected, the microcontroller generates a wireless notification to a computing unit associated with the microcontroller through a communication, notifying a caretaker to the necessary action. The communication module mentioned herein includes, but not limited to Wi-Fi (Wireless Fidelity) module, Bluetooth module, GSM (Global System for Mobile Communication) module. The communication module used in the device is preferably the Wi-Fi module. The Wi-Fi module enables wireless communication by transmitting and receiving data over radio frequencies using IEEE 802.11 protocols. It connects to a network via an access point, converting digital data into radio signals. The module processes TCP/IP protocols for data exchange, interfaces with microcontrollers through UART/SPI, and ensures encrypted communication using WPA/WPA2 security standards for secure and efficient wireless connectivity.

[0036] The motorized rollers 106 are developed to receive manual input overrides through a user interface on the computing unit. This feature allows the user to adjust the tension of the straps 103 according to their comfort preferences. By providing this control, the system ensures that the user can customize the fit and support of the device. The user can increase or decrease the strap tension as needed, enhancing comfort and support while adapting to their physical condition throughout the day.

[0037] As the device is activated through the push button, the microcontroller activates a load cell embedded in the member 102 to detect the weight of the user’s belly. As the belly of the user applies pressure to the member 102, the applied force is transmitted directly onto the load cell which comprises of strain gauges that are small electrical devices bonded to a metal body of the load cell. The metal body deforms slightly under applied pressure and the body stretches or compresses the strain gauges. The deformation of the metal body changes the electrical resistance of the gauges which alters the voltage output of the strain gauge connection. The load cell converts this voltage change into a force measurement which is then translated into a readable force measurement, which indicates the pressure applied by the belly on the member 102, which is then sent to microcontroller for further processing.

[0038] In order to support the user's belly at different stages of pregnancy, the microcontroller gradually deploys a number of curved plates integrated within the member 102 by activating a clamshell assembly 110 within the frontal arc of the member 102 based on the pressure value determined by the load cell.

[0039] The clamshell assembly 110 operates using the curved plates joined by a hinge joint along one edge, enabling them to pivot open and closed like a shell. When opened, the plates provide full access to the interior for inserting or servicing components. Upon closing, alignment features such as pins or grooves ensure proper fit, while locking arrangement like latches, snap-fits, or screws secure the enclosure. Internally, molded supports or compartments hold components in place The closed shell acts as a protective housing, and its reusable nature allows repeated access without compromising structural integrity.

[0040] In order to enhance the support over the belly of the user, the microcontroller actuates a plurality of curved winches 201 coiled with an inflatable membrane 202 arranged across the member 102 for unwrapping the membrane 202 across the member 102. The winch operates by using a rotating drum or spool around which the membrane 202 is wound. A motor is actuated by the microcontroller to rotate the drum through a crank. When the drum rotates, it coils or uncoils the membrane 202, depending on the direction of rotation. A gear arrangement increases torque, enabling the winch to handle heavy loads with minimal effort.

[0041] Upon deploying the membrane 202, the microcontroller actuates an inflating unit to inflate the membrane 202 to a predefined pressure level in order to provide a biochemical comfort during growth stage. The inflating unit inflates the inflatable membrane 202 by directing pressurized air into the membrane 202. The inflation process begins with an air compressor that draws in ambient air through a filter to remove impurities. The compressor then compresses the air using a piston, increasing the pressure of the drawn air. The high-pressure air is either stored in a reservoir or directly supplied to the bags, through an air hose connected to the valve stem of the membrane 202. The valve stem opens to allow air to enter the bags and seals to prevent backflow.

[0042] A foetal monitoring unit installed on the member 102, including a taco dynamometer, a Doppler ultrasound sensor and a three-axis accelerometer coupled with an EMG (electromyography) sensor, is activated by the microcontroller for detecting uterine contractions, foetal heartbeat tracking, and foetal movement along with muscular responses of foetus. The taco dynamometer measures uterine contractions by detecting the pressure exerted during contractions. The taco dynamometer consists of a pressure sensor, as the uterus contracts, the pressure increases, causing strain on the pressure sensor. This strain is converted into an electrical signal, which is processed to determine the strength, duration, and frequency of contractions. The taco dynamometer’s measurements provide real-time data that helps monitor labor progress, ensuring accurate assessment of uterine activity during childbirth. The data is then sent to the microcontroller for further processing.

[0043] The Doppler ultrasound sensor detects the fetal heartbeat by using high-frequency sound waves. The Doppler ultrasound sensor emits these sound waves, which travel through the mother's body and bounce off moving fetal heart. As the fetal heart beats, it causes blood to flow, and the movement of the blood reflects the sound waves. The Doppler effect occurs when the frequency of the reflected sound waves changes due to the motion of the blood. The Doppler ultrasound sensor detects these frequency changes, which are then processed and converted into electrical signals which resembles the heat of the fetus. The converted electrical is sent to the microcontroller for further processing.

[0044] The data from the foetal monitoring unit is processed and compared by the microcontroller with a pre-saved in the database in order to monitor the health of the foetus and identify anomalies and fetch nutritional recommendation, stress mitigation strategies and personalized healthcare guidance to promote maternal and foetus well-being.

[0045] Upon determining the health and development status of the foetus, the microcontroller activates a holographic projection unit 111 mounted on the member 102 for projecting the determined information in a form of three-dimensional image. The holographic projection unit 111 projects a 3D image of the gathered information by converting digital data generated by the microcontroller into an interference pattern using coherent light. The interference pattern is then projected into the space and the light diffracted by the interference pattern reconstructing the 3D image of the gathered information. The resulting holographic image appears to be displayed on the surface.

[0046] In case of prolonged use, the microcontroller activates a flex sensor installed on the straps 103 for measuring any strain experienced by the user. The flex sensor detects strain on the user's shoulders due to prolonged use by measuring the amount of bending or flexing in the sensor. The flex sensor is typically a thin strip of material that changes resistance when bent. When the sensor is attached to a user's shoulder area, any movement or change in the angle of the shoulder (such as raising or lowering) causes the sensor to bend. The bending alters the sensor's resistance, which is then measured by the microcontroller. The greater the bending or flexing, the higher the strain, which results in a greater change in resistance. This change is translated into data that helps determine the strain on the user's shoulders. The determined strain is then sent to the microcontroller for further processing. Based on the determined strain on the shoulder of the user, the microcontroller regulates the actuation of the rollers to adjust the tightness of the straps 103 around the shoulders in order to ensure a comfortable fit.

[0047] Upon adjusting the tightness of the straps 103, the microcontroller actuates a plurality of motorized iris operated lids 112 installed on the straps 103, each housed with an electronic sprayer 113 that sprays a reliving liquid from a vessel 114 configured with the sprayer 113 over the portions where strain is experienced. The iris lid 112 is an adjusting circular aperture comprised of an actuation ring and a plurality of blades according to the size of the lid 112. The blades are engraved with the protrusions through which the actuation ring is affixed to each blade. The actuation ring is connected to a control arrangement, such as a motor, which helps in the movement of the actuation ring leading to the movement of blades inward or outward to change the size of the opening. When the blades close, the aperture becomes smaller, closing the lid 112. When the blades open, the aperture widens, opening the lid 112.

[0048] Upon opening the lid 112, the sprayer 113 is actuated by the microcontroller for spraying the reliving liquid. The sprayer 113 comprises of a gate and a magnetic coil which uses electricity from microcontroller to generate the force to control the opening/closing of gate to control the flow of the relieving liquid through a small aperture of the sprayer 113, allowing for precise control of the flow of the liquid on the portion where strain is experienced.

[0049] In synchronization of the sprayer 113, the microcontroller actuates a water pump arranged in the vessel 114 for pushing the liquid towards the sprayer 113 for spraying. The pump works by converting mechanical energy into hydraulic energy to move the liquid from the vessel 114 to the sprayer 113. The pump consists of a motor or engine that drives an impeller, a rotating component inside the pump. As the impeller spins, it creates suction that draws liquid into the pump and pushes the drawn liquid out through the outlet.

[0050] Moreover, 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 electrodes known as a cathode and an anode. A voltage is generated between the anode and cathode via oxidation/reduction and thus produces the electrical energy to provide to the device.

[0051] The present invention, works best in the following manner, where the frame 101 with the curved structural member 102 are contoured to fit around the upper back and shoulders. The frame 101 holds looped straps 103, each with the first and second portion, and flexible belts 104 are affixed across the straps 103 to support the spinal region. The user activates the device via the push button, which closes the circuit to power the device. The artificial intelligence-based imaging unit 105 captures images of the user’s body, and the data is processed to determine body dimensions. The motorized rollers 106 adjust strap tension based on the body dimensions, ensuring the comfortable fit. The infrared proximity sensor measures the distance between the frame 101 and ground, enabling adjustment of extendable legs 107 for support. The cascading slider assembly operates in the sequence to extend the legs 107, and the infrared sensor calibrates terrain inclination and gait cycle, adapting leg 107 extension accordingly. The health monitoring module includes the PPG sensor to measure cardiovascular parameters, infrared temperature sensor for body temperature, and inertial measurement units (IMUs) to track movement. Data is analyzed for potential risks to maternal and fetal health. The microcontroller activates the holographic projection unit 111 to display health information and the flex sensor detects shoulder strain. The motorized iris lids 112 and sprayer 113 provide relief by applying the soothing liquid to strained areas.

[0052] Although the field of the invention has been described herein with limited reference to specific embodiments, this description is not meant to be construed in a limiting sense.
