Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a multifunctional smart nursing pad. Background Technology

[0002] Breastfeeding is the ideal source of nutrition for infants and young children, and breast milk is crucial for their growth, development, and the establishment of their immune system. However, some new mothers still face many challenges when breastfeeding in specific environments (such as public places, at night, and during long periods of breastfeeding). Traditional nursing pads (or nursing covers, nursing shields) primarily function to provide some privacy during breastfeeding. They are simple in structure, usually made of a single piece of fabric, and have a single function.

[0003] In existing technologies, such as the nursing pillow with model number IY8015YL, a U-shaped wraparound design can conform to the curve of the pregnant woman's waist to distribute the baby's weight, reduce the burden on the arms and waist, and prevent complications such as frozen shoulder and cervical spondylosis during lactation. It also uses a slow rebound memory foam core to provide flexible support, adapt to different breastfeeding positions, and avoid the problem of traditional pillows collapsing. It is fixed to the waist with an adjustable buckle to prevent it from slipping, making it easy to operate with one hand.

[0004] The aforementioned products, with their fixed support design, may not be able to be flexibly adjusted according to the mother's body shape or breastfeeding posture. If they are too wide, they cannot provide effective support; if they are too narrow, they will compress the body, requiring constant manual adjustment during use, which affects breastfeeding efficiency and experience. Furthermore, their internal filling has a high density and few pores, which hinders air circulation, resulting in low breathability and comfort. Therefore, it is necessary to propose a comfortable and portable multifunctional smart nursing pad. Summary of the Invention

[0005] To address the aforementioned issues, this invention provides a multifunctional smart nursing pad that adaptively expands according to the user's body shape. By coordinating the linkage between the inertial measurement unit and the solenoid valve in real time, it can dynamically adjust the contact pressure and the breathability of the support arc when changing posture, thereby improving device comfort and reducing the operational threshold, making it suitable for scenarios requiring one-handed operation during breastfeeding.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: a multifunctional intelligent nursing pad, comprising a pad body, the pad body integrating a main strap, a support mechanism for providing adaptive support and temperature control adjustment, and a breathable and deformable shielding mechanism.

[0007] The main belt is set along one edge of the pad body, and a controller, inertial measurement unit, environmental sensor and air supply component are fixedly connected to the outer wall of the main belt. The support mechanism includes a support airbag, a circulation airbag and several solenoid valves. The circulation airbag is connected to the support airbag through the solenoid valves. The support airbag is fixedly connected to the inner wall of the main belt, and the circulation airbag is fixedly connected to the outer wall of the support airbag. The shielding mechanism includes a support arc extending from the pad body and an electrochromic fabric layer covering the outer wall of the support arc. The support arc is hinged to the main belt, and both the support airbag and the support arc are connected to the output end of the air supply component.

[0008] The pad body is also equipped with a switch mechanism for starting the device. The switch mechanism includes a male buckle and a female buckle with conductive plates. The male buckle and the female buckle are detachably connected. When the male buckle and the female buckle are in contact, the circuit is turned on to trigger the inertial measurement unit to detect the status of the pad body and start the air supply component to inflate.

[0009] The technical principles of the above solution are as follows:

[0010] The switching mechanism uses male and female snaps with conductive plates. When they are engaged, the circuit is activated, triggering the inertial measurement unit to detect the status of the pad body. Upon confirmation, the air supply component is activated to inflate. The support mechanism controls the gas flow between the support airbag and the circulating airbag via a solenoid valve, providing adaptive support. After the support arc unfolds, it provides privacy through the electrochromic fabric on its outer wall, which can adjust light transmittance based on environmental sensor signals. The controller coordinates the operation of each component, sensing user movements through the inertial measurement unit and combining this with environmental sensor data to dynamically adjust the support pressure and privacy status.

[0011] The above approach has the following beneficial effects:

[0012] 1. The switching mechanism of this solution adopts a male and female snap-fit ​​design with conductive plates. Users only need to simply attach the snap-fit ​​to trigger the circuit, without complicated buttons or setup procedures. After the circuit is activated, the inertial measurement unit automatically detects the status of the pad body to ensure that the air supply component is activated under the correct wearing posture, avoiding false triggering. The support airbag can adaptively expand according to the user's body shape. Through real-time coordination between the inertial measurement unit and the solenoid valve, the contact pressure and air permeability of the support arc can be dynamically adjusted when changing posture, improving device comfort and reducing the operating threshold, making it suitable for one-handed operation during breastfeeding.

[0013] 2. This solution utilizes a dual-airbag design and solenoid valve control to create a dynamic design for support and temperature control. The support airbag conforms to the body's curves, and the pressure adapts to the user's body shape through solenoid valve inflation control, dynamically adjusting the contact area and support intensity to avoid localized pressure. The circulating airbag is connected to the outer wall of the support airbag, and the periodic on / off operation of the solenoid valve drives gas circulation, forming a micro-convection airflow channel that effectively removes localized heat and moisture, solving the problem of stuffiness and sweat buildup caused by the sealed fit of traditional nursing pads. The composite structure of the dual airbags combines elastic cushioning and breathability, providing stable support while allowing for moderate deformation with body movement, balancing support rigidity and wearing comfort to meet the body's need for relief during prolonged breastfeeding sessions.

[0014] 3. This solution combines a support arc with electrochromic fabric to achieve a dynamic balance between privacy protection and environmental adaptability. The support arc unfolds to create a three-dimensional privacy space; the outer electrochromic fabric adjusts its light transmittance based on environmental sensor signals; it automatically deepens its color in strong light to enhance privacy, while maintaining a semi-transparent state in low light to avoid visual oppression, while also allowing for airflow. The hinged structure between the support arc and the main strap allows for multi-angle rotation, enabling users to adjust the privacy angle according to their breastfeeding posture, balancing privacy needs with operational flexibility in different scenarios, and enhancing the mother-infant interaction experience.

[0015] Furthermore, the support mechanism also includes a distributed sensor network for acquiring contact pressure and temperature information, which includes a piezoresistive thin-film sensor array and a body temperature sensor patch laid between the support airbag and the circulating airbag.

[0016] The piezoresistive thin-film sensor array is used to monitor the pressure distribution data on the surface of the pad body in real time and transmit the pressure distribution data to the controller.

[0017] The controller controls the operation of the solenoid valve and air supply components based on the pressure distribution data, and adjusts the inflation and deflation of the circulating airbag to adjust the supporting force of the cushion body.

[0018] Beneficial effects: By monitoring pressure distribution in real time through a piezoresistive thin-film sensor array and combining it with data from a body temperature sensor patch, the controller dynamically adjusts the solenoid valve and air delivery components to inflate and deflate the support airbag and circulating airbag. The support force can adapt to changes in body curves and posture, avoiding localized pressure and improving fit and comfort. At the same time, the gas circulation optimizes temperature control, enhancing the dynamic adaptability of the support mechanism and the user experience.

[0019] Furthermore, the controller is also used to identify the high-pressure and low-pressure zones of the support airbag based on the pressure distribution data of the piezoresistive thin-film sensor array; and to control the opening and closing of the solenoid valve based on the information of the high-pressure and low-pressure zones, so that the gas in the support airbag flows into the low-pressure zone of the circulating airbag through the solenoid valve, while the gas is exhausted from the high-pressure zone; in order to match the body curve.

[0020] Beneficial effects: Distributed sensors identify high and low pressure zones in the support airbag, driving solenoid valves to dynamically allocate gas: gas in the high-pressure zone flows through the solenoid valve to the low-pressure zone of the circulating airbag and is simultaneously exhausted, achieving precise pressure balance. This mechanism can adapt to the body's curves in real time, reducing localized pressure, improving support fit and stability, avoiding soreness caused by uneven pressure, and enhancing comfort and adaptability during dynamic use.

[0021] Furthermore, the environmental sensors include an ambient light sensor and a temperature and humidity sensor; the controller controls the light transmittance of the electrochromic fabric based on the data from the ambient light sensor: when the detected ambient light is higher than the threshold, the light transmittance is reduced to enhance privacy; when the ambient light is lower than the threshold, the light transmittance is maintained to improve breathability.

[0022] Beneficial effects: By monitoring light intensity through an ambient light sensor, the controller dynamically adjusts the light transmittance of the electrochromic fabric accordingly: reducing transmittance to enhance privacy in strong light and maintaining high transmittance to improve breathability in low light. This design achieves an intelligent balance between privacy protection and breathability, avoiding the fixed transmittance defects of traditional shielding components, adapting to different lighting environments, and improving user comfort and scene adaptability.

[0023] Furthermore, the air supply components and solenoid valves in the main belt body are connected to the support arc, support airbag and circulation airbag through an integrated air circuit; when the power switch of the switching mechanism is closed and energized, the air supply components first inflate the support arc to form a shielding frame, and then inflate the support airbag.

[0024] Beneficial effects: The integrated air circuit connection simplifies the piping structure of the air supply components and each airbag, reduces component redundancy, and improves response efficiency and reliability. The step-by-step inflation design prioritizes inflating the support arc to form a shielding frame, ensuring privacy protection first, and then provides a close fit for the support airbags, preventing structural shaking during inflation and enhancing user safety and operational smoothness.

[0025] Furthermore, the support mechanism also includes heating wires integrated into the inner wall of the pad body; the controller controls the heating wires to heat the air flowing into the support airbag and the circulating airbag based on the data from the body temperature sensor patch and the temperature and humidity sensor, and controls the output rate of the air supply component to dissipate heat in order to maintain a comfortable temperature.

[0026] Beneficial effects: The temperature and humidity sensor works in conjunction with the body temperature sensor to monitor the ambient and human body temperature. Based on this, the controller dynamically adjusts the heating wire's airflow and regulates the air delivery rate for heat dissipation, achieving precise temperature control. It can adapt to changes in the environment and human body needs in real time, avoiding excessive cold or heat, continuously maintaining a comfortable temperature range, and improving the stability and environmental adaptability of the user experience.

[0027] Furthermore, the pad body is made of breathable and waterproof fabric; the main belt has a waterproof encapsulation structure.

[0028] Beneficial effects: The pad body is made of breathable and waterproof fabric and supports full washing, taking into account both breathability and ease of cleaning. The waterproof encapsulation structure of the main body ensures the safety of the circuit and air circuit system, and improves the product's durability and ease of maintenance.

[0029] Furthermore, the inertial measurement unit is used to detect the curled-up static state and the flat-lay-out state of the mat body; when switching from the curled-up static state to the flat-lay-out state, the inertial measurement unit sends a signal to the controller, and the controller controls the opening and closing of the solenoid valve to expel the gas inside the mat body.

[0030] Beneficial effects: The inertial measurement unit automatically detects whether the mat is curled or flat, and triggers the solenoid valve to release gas when switching to unfolding mode, achieving automated gas release control without manual operation. Timely removal of residual gas ensures the mat unfolds flat, avoiding poor adhesion or structural wobbling caused by gas residue, improving ease of use and smooth operation, and enhancing scene adaptability and user experience.

[0031] Furthermore, the circulating airbag consists of several auxiliary airbags, all of which are connected to the supporting airbag via solenoid valves; the controller independently inflates and deflates the auxiliary airbags in specific areas by selectively opening and closing the solenoid valves.

[0032] Beneficial effects: By controlling the independent inflation and deflation of the auxiliary airbag through the solenoid valve, the air pressure can be adjusted for specific areas to meet the personalized support needs of different parts; dynamically adapting to changes in user body shape and posture, avoiding local pressure concentration, improving fit and comfort, enhancing the product's adaptability to diverse scenarios, and optimizing the user experience.

[0033] Furthermore, a storage layer is fixedly connected to the outer wall of the cushion body, and an auxiliary airbag is fixedly connected to the inner wall of the storage layer.

[0034] Beneficial effects: The storage layer provides convenient storage space. The auxiliary airbag is fixed to its inner wall and connected to the support airbag through a solenoid valve. It can be independently inflated and deflated to adjust the support of the storage layer, flexibly adapting to the storage needs of different items and improving ease of use; it enhances the practicality and adaptability of the product, maintaining a balance between compact structure and functional integration; when storing milk bags, the design of the independent auxiliary airbag can provide flexible support, improving the adaptability of the device.

[0040] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] The following detailed description illustrates the specific implementation method:

[0042] The basic implementation examples are as follows: Figures 1-4 As shown: A multifunctional smart nursing pad includes a pad body 1, which integrates a main strap 2, a support mechanism for providing adaptive support and temperature control, and a breathable and deformable covering mechanism. The pad body 1 is made of breathable and waterproof fabric and is entirely washable; the main strap 2 has a waterproof encapsulation structure. Specifically, the pad body 1 uses breathable and waterproof fabric and supports complete washing, balancing breathability and ease of cleaning. The waterproof encapsulation structure of the main strap 2 ensures the safety of the circuit and air circuit system, improving product durability and ease of maintenance.

[0043] The main belt 2 is set along one edge of the pad body 1. The controller, inertial measurement unit, environmental sensor and air supply component 8 are fixedly connected to the outer wall of the main belt 2 by screws. The controller can be a PLC, CPU, microcontroller and main control MCU. In this embodiment, the main control MCU is selected. The air supply component 8 is an air pump. The support mechanism includes a support airbag 3, a circulation airbag 4 and several solenoid valves. The circulation airbag 4 is connected to the support airbag 3 through the solenoid valves. The support airbag 3 is fixedly bonded to the inner wall of the main belt 2. The circulation airbag 4 is fixedly bonded to the outer wall of the support airbag 3. The shielding mechanism includes a support arc 5 extending from the pad body 1 and an electrochromic fabric layer covering the outer wall of the support arc 5. The support arc 5 is hinged to the main belt 2. The support airbag 3 and the support arc 5 are both connected to the output end of the air supply component 8.

[0044] The circulating airbag 4 consists of several auxiliary airbags, all of which are connected to the support airbag 3 via solenoid valves. The controller selectively opens and closes the solenoid valves to independently inflate and deflate the auxiliary airbags in specific areas. Specifically, by controlling the independent inflation and deflation of the auxiliary airbags through the solenoid valves, the air pressure can be adjusted for specific areas to meet the personalized support needs of different parts of the body; it dynamically adapts to changes in the user's body shape and posture, avoids local pressure concentration, improves fit and comfort, enhances the product's adaptability to diverse scenarios, and optimizes the user experience.

[0045] The pad body 1 is also provided with a switch mechanism for starting the device. The switch mechanism includes a male buckle 6 and a female buckle 7 with conductive plates. The male buckle 6 and the female buckle 7 are detachably magnetically connected. When the male buckle 6 and the female buckle 7 are connected, the circuit is turned on to trigger the inertial measurement unit to detect the state of the pad body 1 and start the air supply component 8 to inflate.

[0046] Specifically, the user attaches the male buckle 6 and the female buckle 7 together, and the conductive sheet contacts to make the circuit conduction, triggering the inertial measurement unit to detect the status of the pad body 1. After confirming the status, the controller starts the air supply component 8 to inflate. The support airbag 3 and the circulation airbag 4 cooperate through the solenoid valve to complete the inflation process, so that the pad body 1 unfolds and forms an adaptive support structure. At the same time, the shielding mechanism enters the standby state as the pad unfolds, realizing the automatic start-up and functional preparation of the device.

[0047] The support mechanism also includes a distributed sensor network for acquiring contact pressure and temperature information. The distributed sensor network includes a piezoresistive thin film sensor array and a body temperature sensor patch laid between the support airbag 3 and the circulating airbag 4.

[0048] The piezoresistive thin-film sensor array is used to monitor the pressure distribution data on the surface of the pad body 1 in real time and transmit the pressure distribution data to the controller. The controller controls the operation of the solenoid valve and the air supply component 8 according to the pressure distribution data, and adjusts the inflation and deflation of the circulating airbag 4 to adjust the support force of the pad body 1.

[0049] The controller is also used to identify the high-pressure and low-pressure zones of the support airbag 3 based on the pressure distribution data of the piezoresistive thin-film sensor array; and to control the opening and closing of the solenoid valve based on the information of the high-pressure and low-pressure zones, so that the gas in the support airbag 3 flows into the low-pressure zone of the circulating airbag 4 through the solenoid valve, while exhausting from the high-pressure zone; in order to match the body curve.

[0050] Specifically, the pressure distribution on the surface of the pad body 1 is monitored in real time by a piezoresistive thin-film sensor array. This information is transmitted to the controller, which identifies the high-pressure and low-pressure zones of the support airbag 3. Subsequently, the controller selectively opens and closes the solenoid valve, guiding the gas within the support airbag 3 to flow through the solenoid valve to the low-pressure zone of the circulating airbag 4, while simultaneously venting the high-pressure zone. This process dynamically adjusts the inflation and deflation of the circulating airbag 4, allowing the support force to adapt to the body's curves in real time, achieving adaptive adjustment of the support strength.

[0051] The environmental sensors include an ambient light sensor and a temperature and humidity sensor; the controller controls the light transmittance of the electrochromic fabric based on the data from the ambient light sensor: when the detected ambient light is higher than the threshold, the light transmittance is reduced to enhance privacy; when the ambient light is lower than the threshold, the light transmittance is maintained to improve breathability.

[0052] The air supply component 8 and solenoid valve inside the main belt 2 are connected to the support arc 5, support airbag 3 and circulation airbag 4 through an integrated air circuit; when the power switch of the switching mechanism is closed and energized, the air supply component 8 first inflates the support arc 5 to form a shielding frame, and then inflates the support airbag 3.

[0053] The support mechanism also includes heating wires integrated into the inner wall of the pad body 1; the controller controls the heating wires to heat the air flowing into the support airbag 3 and the circulating airbag 4 based on the data from the body temperature sensor patch and the temperature and humidity sensor, and controls the output rate of the air supply component 8 to dissipate heat in order to maintain a comfortable temperature.

[0054] Specifically, during the environmental adaptation and temperature control process, after the switching mechanism is powered on, the air supply component 8 first inflates the supporting arc 5 to form a shielding frame. The ambient light sensor monitors the light intensity in real time, and the controller adjusts the light transmittance of the electrochromic fabric of the shielding mechanism accordingly. When the light is strong, the light transmittance is reduced to enhance privacy protection, and when the light is weak, the light transmittance is maintained to optimize breathability. At the same time, the temperature and humidity sensor and the body temperature sensor patch in the distributed sensor network work together to collect environmental and contact temperature information. After comprehensive analysis, the controller activates the heating wire to heat the air flowing into the supporting airbag 3 and the circulating airbag 4, and controls heat dissipation by adjusting the output rate of the air supply component 8 to balance the temperature and maintain a comfortable use environment, thus achieving a coordinated response between environmental perception and temperature control.

[0055] The inertial measurement unit is used to detect the curled-up static state and the flat-lay-out state of the mat body 1. When switching from the curled-up static state to the flat-lay-out state, the inertial measurement unit sends a signal to the controller, and the controller controls the opening and closing of the solenoid valve to expel the gas in the mat body 1.

[0056] Specifically, when the smart nursing pad switches from a rolled-up, stationary state to a flat, unfolded state, the inertial measurement unit captures the attitude change of the pad body 1 in real time and sends a state switching signal to the controller. Upon receiving the signal, the controller coordinates the solenoid valves in the support mechanism to open the preset exhaust channels. At this time, the gas in the support airbag 3 and the circulation airbag 4 is orderly discharged under the action of pressure difference through the directional opening and closing of the solenoid valves. During the process, the controller, combined with real-time feedback from the distributed sensor network, dynamically adjusts the opening and closing degree of the solenoid valves in each area to ensure that the gas is preferentially discharged from the high-pressure area, while avoiding excessive exhaust that could affect the basic support. As the gas is gradually released, the volume of the support airbag 3 and the circulation airbag 4 adaptively contracts, cooperating with the flat unfolding action of the pad body 1, so that the overall structure naturally unfolds, completing the gas pressure balance and support shape adjustment from the rolled-up to the flat state.

[0057] The outer wall of the pad body 1 is also fixedly sewn to a storage layer 9, and an auxiliary airbag is also fixedly adhered to the inner wall of the storage layer 9. Specifically, the storage layer 9 provides convenient storage space, and the auxiliary airbag is fixed to its inner wall and connected to the support airbag 3 through a solenoid valve. It can independently inflate and deflate to adjust the support of the storage layer 9, flexibly adapting to the storage needs of different items and improving ease of use; enhancing the practicality and adaptability of the product, and maintaining a balance between compact structure and functional integration; when storing milk bags, the design of the independent auxiliary airbag can provide flexible support, improving the adaptability of the device.

[0058] This embodiment achieves a multi-faceted experience upgrade through deep component linkage. The storage layer 9, with its auxiliary airbag linkage support system, expands the storage function. After the switch is triggered, the inertial measurement unit automatically detects the status, and the linkage air supply component 8 and the solenoid valve complete the inflation and deflation balance, improving storage convenience. The distributed sensor network captures pressure and temperature in real time, and the controller drives the solenoid valve to dynamically adjust the support force to adapt to the body curve. In conjunction with the ambient light sensor, it adjusts the light transmittance of the electrochromic fabric (enhancing privacy in strong light and improving breathability in weak light) and temperature and humidity are coordinated for temperature control, forming an intelligent closed loop. Compared with traditional products, this represents a significant breakthrough in functional integration, dynamic adaptation, and comfort experience.

[0059] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
