[0014] Please see Figure 1-2 This utility model provides an intelligent nursing mattress system, comprising: The mattress body includes a surface layer 1, a sensor layer 2, an execution layer 3, and a base frame layer 4, which are stacked from top to bottom. The sensor layer 2 is provided with several grid nodes. The data acquisition module 5 includes a pressure sensor array and a physiological signal sensor. The pressure sensor array is embedded in the grid nodes of the sensor layer 2, and the physiological signal sensor is installed on the back of the surface layer 1. The physiological signal sensor includes at least: a bio-radar sensor, temperature, humidity, and pressure sensors, a timer, etc. The bio-radar sensor is integrated into the mattress and is used to monitor the user's respiratory rate and heart rate data. The temperature, humidity, and pressure sensors are evenly distributed on the surface of the mattress and are used to monitor the user's body temperature, body position, and other data. The timer is used to monitor the duration of each data point. The execution module 6 includes a multi-axis adjustment unit 11, a pressure relief unit 12, a back tapping unit 14, and an excretion care unit 13, which are used to adjust the user's body position and breathing status and provide excretion care. The multi-axis adjustment unit 11 is installed on the base frame layer 4, the pressure relief unit is installed on the execution layer 3, the back tapping unit 14 penetrates the surface layer 1 and the execution layer 3 and is installed on the base frame layer 3, and the excretion care unit 13 penetrates each layer and is installed on the base frame layer 3. The intelligent control module 7 is connected to the data acquisition module 5 and the execution module 6 via circuit boards. The mutual exclusion control unit 8 is integrated into the circuit board of the intelligent control module 7; The communication module 9 is connected to the external device 10 and the intelligent control module 7 via connectors, which are connector structures.

[0015] It should be explained that after the mattress care system is assembled and tested, when the user lies on the mattress, the data acquisition module 5 monitors the mattress pressure distribution data and physiological data, and based on the monitoring data, controls each unit to work together automatically to perform operations such as preventing bedsores, preventing muscle atrophy, breathing difficulties and excretion care for the user, thereby improving the quality of care and comfort of the mattress for the user.

[0016] Furthermore, the multi-axis adjustment unit 11 includes: The backrest mechanism is located at the bottom of any end of the mattress body along its length, with the user's hips and waist as the dividing line. The backrest mechanism includes a back support plate and a hydraulic push rod. One end of the back support plate is hinged to the base frame layer 4 at the hip and waist dividing line. One end of the hydraulic push rod is hinged to the tail end of the base frame layer 4, and the other end is hinged to the bottom of the back support plate. A turning mechanism is symmetrically arranged on both sides of the mattress body. The turning mechanism includes side wing support plates. The opposite ends of each side wing support plate are hinged to the top of the base frame layer 4. A synchronous lifter is provided between the base frame layer 4 and the side wing support plates. One end of the synchronous lifter is hinged to the outside of the base frame layer 4, and the other end is hinged to the bottom of the side wing support plate.

[0017] Understandably, when abnormal breathing is detected in the user, the intelligent control module 7 controls the hydraulic push rod to extend and push the back support plate to rotate, thereby raising the user's back and improving the user's breathing. When excessive local pressure is detected on the mattress surface (such as pressure on the arms or legs), the synchronous lifter performs a side-turning operation on the user to improve the pressure distribution.

[0018] Furthermore, the pressure relief unit 12 includes: Several airbag groups are evenly distributed on the top of the execution layer 3, and each airbag group includes several interconnected airbag units. Each airbag assembly is provided with a physical isolation layer, and each airbag assembly is connected to an air pump device through an independent air passage, which is a silicone tube.

[0019] Specifically, when excessive local pressure is detected over a prolonged period, the intelligent control module 7 controls the airbag assembly in that area to periodically inflate and deflate, simulating manual massage to improve local pressure.

[0020] Furthermore, the back-tapping unit 14 includes: An array of multiple rows of tapping blocks 15 are arranged longitudinally along the spinal region of the mattress body. Each tapping block 15 has a lifting rod 16 fixed at its bottom. The lower end of the lifting rod 16 passes through the execution layer 3 and is connected to a drive box 17. The drive box 17 is used to drive the lifting rod 16 to move up and down reciprocally. The drive box 17 includes: a servo motor fixed on the base frame layer 4, an eccentric wheel sleeved on the output end of the servo motor, and a connecting rod with one end hinged to the lifting rod 16 and the other end eccentrically hinged to the eccentric wheel.

[0021] It is understandable that the servo motor drives the eccentric wheel to rotate, causing the lifting rod 16 to move up and down repeatedly, which in turn drives the patting block 15 to pat and massage the user's back.

[0022] Furthermore, the excretion care unit 13 includes: A toilet bowl, the top of which is embedded in the opening of the surface layer 1, and a sealing ring is provided at the edge of the opening; the bottom outlet of the toilet bowl is sealed to an electric sewage collection valve, and a collection chamber is detachably installed at the bottom of the electric sewage collection valve, and a sealing structure (sealing ring) is provided at the connection between the electric sewage collection valve and the collection chamber. Cleaning nozzles are arranged in a ring on the inner wall of the toilet bowl, and the cleaning nozzles are connected to the water tank through a telescopic tube. An annular air duct is embedded in the side wall of the toilet bowl. A PTC heating element is integrated inside the air duct to blow hot air out of the annular air duct to dry the toilet bowl.

[0023] Specifically, the PTC (positive temperature coefficient thermistor) heating element is fixed near the air inlet of the annular air duct. A miniature fan is installed at the air inlet of the annular air duct to draw air into the air duct. After the air passes through the PTC heating element, it forms hot air, which is then discharged through the air outlet to dry the toilet bowl.

[0024] It should be explained that the toilet bowl is equipped with a detection unit for monitoring whether a defecation event has occurred. The detection unit includes at least a thin-film pressure sensor, a temperature sensor, a humidity sensor, and an odor sensor installed inside the toilet bowl.

[0025] Based on monitoring data, the control system coordinates and automatically performs operations such as preventing bedsores, preventing muscle atrophy, managing respiratory distress, and providing excretion care for the user. Specifically, this includes: When localized mattress pressure exceeds 32 mmHg for ≥2 hours, a multi-stage composite anti-bedsore mechanism is triggered, including: S1.1 Based on the data collected by the data acquisition module 5, the airbag group in the pressure abnormal area is periodically inflated and deflated, with a deflation cycle of 5 minutes; S1.2 Simultaneously control the back tapping unit 14 to perform lateral tapping vibration. The lateral tapping is tapping at the same tapping frequency as a row of tapping blocks 15 along the width direction of the mattress, and each row of tapping blocks 15 can be at a different tapping frequency. S1.3 Control the multi-axis adjustment unit 11 to automatically tilt the body at a 12~18° lateral angle to improve pressure distribution.

[0026] When the user's respiratory rate is >30 breaths / min and the duration is ≥5min, the respiratory assistance mode is triggered, including: S2.1 Control the backrest lifting mechanism to raise the back area of ​​the mattress to 10~55°; S2.2, Control the pressure relief unit 12 to reduce the air pressure of the airbag in the user's buttock area by 18-22% of the inflation pressure; S2.3. Activate the back tapping unit 14 to perform longitudinal tapping vibration. The longitudinal tapping is tapping at the same tapping frequency as a row of tapping blocks 15 along the length of the mattress, and each row of tapping blocks 15 may be at a different tapping frequency.

[0027] When a defecation event is detected, the defecation care mode is triggered, including: S3.1 Control the electric sewage collection valve to open, and guide the excrement into the collection chamber; S3.2. Start the cleaning module to rinse the user area and the toilet bowl with warm water at a temperature of 35℃±2℃ and a flow rate of 200ml / min. S3.3 After rinsing, perform hot air drying on the user's area and the toilet bowl, with an air temperature of 40℃±10℃ and an air speed of 30m / s, for 1 to 3 minutes. S3.4 After detecting that the user's cleaning area and toilet have reached the preset cleaning standard, shut down each execution unit.

[0028] When the body position is maintained for more than 4 hours, the muscle atrophy prevention mode is automatically triggered, including: S4.1 Based on pressure distribution data, periodically inflate and deflate the airbag in the pressure area, with a pressure gradient of 10-50 mmHg and a frequency of 0.8 Hz. S4.2, and activate the back tapping unit 14 to perform tapping massage with an amplitude of 5-10mm and a frequency of 1.5Hz.

[0029] By using data acquisition module 5 and multiple units to trigger different nursing modes, this addresses the problems of traditional nursing mattresses, such as the lack of targeted pressure ulcer prevention, the lack of proactive intervention mechanisms for respiratory abnormalities, and the need for manual detection and handling of excretion, resulting in poor timeliness.

[0030] Furthermore, the side wing support plate includes: a support steel plate, a buffer layer is provided on the top of the support steel plate, a waterproof cloth is provided on the outside of the buffer layer, and the support steel plate is hinged to the base frame layer 4 through a rotating shaft.

[0031] Specifically, the buffer layer is memory foam, and the two ends of the rotating shaft are mounted on the base layer 4 by ball bearings.

[0032] Furthermore, adjacent eccentric wheels are arranged with a phase difference angle of 15°±1°, and the synchronous rotation of each eccentric wheel can perform a wave-like tapping massage on the user's back.

[0033] Furthermore, the mutual exclusion control unit 8 is a priority judgment control circuit with multiple signal input interfaces, which is connected to the relays of the multi-axis adjustment unit 11, the pressure relief unit 12, the back tapping unit 14, and the excretion care unit 13, respectively. The mutual exclusion control unit 8 is a microprocessor / microcontroller with multiple peripheral serial ports integrated to implement priority operation. The priority judgment control circuit is a common existing circuit form, which is used in computer interrupt systems (such as PIC), bus arbitration, elevator control systems, etc.

[0034] Specifically, in this utility model, the mutual exclusion control unit 8 can be configured to: when the excretion care mode and the anti-bedsore mode conflict, prioritize the response of the excretion care mode; when the breathing assistance mode and the anti-bedsore mode need to respond synchronously, prioritize the execution of the back patting action required by the breathing assistance mode.

[0035] In practice, after the mattress care system is assembled and inspected, when the user lies on the mattress, the data acquisition module 5 monitors the mattress pressure distribution data and physiological data. Based on the monitoring data, the system controls each unit to work together to automatically perform operations such as preventing bedsores, preventing muscle atrophy, relieving breathing difficulties, and providing excretion care, thereby improving the quality and comfort of the care mattress for the user.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
