Technical Field

[0001] This utility model belongs to the field of medical device technology, and relates to a medical mattress, and more particularly to a multi-functional mesh mattress that integrates dynamic pressure reduction and intelligent monitoring. Background Technology

[0002] Medical mattresses are special mattresses designed and manufactured specifically for hospitals. They aim to provide patients with a comfortable resting environment while meeting medical needs. They typically use highly elastic materials to relieve pressure caused by prolonged bed rest and help promote blood circulation. In addition, the surface materials of these mattresses are mostly breathable and easy to clean, facilitating daily cleaning and disinfection in hospitals. In the hospital environment, the importance of medical mattresses cannot be ignored. They not only concern the patient's comfort but also directly affect the patient's recovery. A suitable medical mattress can effectively reduce the patient's physical pressure, promote recovery, and reduce the risk of complications.

[0003] As a core piece of equipment for the care of critically ill patients, medical mattresses, in the current technology, usually use fixed filling materials and lack adjustable air chambers or sensor components. They cannot adjust the support force in real time according to the pressure distribution of the human body, resulting in long-term local pressure, increasing pressure injuries, such as increasing the risk of bedsores for patients, and affecting the patient's user experience.

[0004] Therefore, it is necessary to propose a multi-functional mesh mattress with dynamic pressure reduction and intelligent monitoring to solve the technical problem that medical mattresses cannot avoid localized continuous pressure. Utility Model Content

[0005] The technical problem to be solved by this utility model is: in view of the defects of the prior art, a multi-dimensional mesh mattress with dynamic decompression and intelligent monitoring is provided, which has the advantage of good user experience for patients and solves the problem that medical mattresses cannot avoid local continuous pressure.

[0006] To solve the above-mentioned technical problems, this utility model adopts the following technical solution:

[0007] A multi-functional mesh mattress integrating dynamic pressure reduction and intelligent monitoring includes a surface layer, a functional layer and an inflatable pad body connected from top to bottom, wherein a dynamic pressure reduction component is provided on the inflatable pad body.

[0008] The dynamic pressure reduction component includes several air chamber units and several air passages connected to the air chamber units. The air chamber units are arranged in a honeycomb matrix. Several micro air pumps are provided between the inflatable cushion and the air chamber units. The air passages are connected to the output ends of the micro air pumps.

[0009] Preferably, the cross-sectional shape of the air chamber unit is a regular hexagon, and adjacent air chamber units are connected in parallel through air passage pipes.

[0010] Preferably, the inflatable cushion is provided with a main control unit, and the air passage is provided with a solenoid valve, which is electrically connected to the main control unit.

[0011] Preferably, a plurality of pressure sensor grids are provided at equal intervals on the inner sidewall of the air chamber unit, and the pressure sensor grids are signal connected to the main control unit.

[0012] Preferably, the functional layer includes a fabric layer and a middle layer, the fabric layer is located above the middle layer, a flexible capacitive sensor is embedded in the fabric layer, and an impedance measuring electrode is embedded in the middle layer. Both the flexible capacitive sensor and the impedance measuring electrode are signal connected to the main control unit.

[0013] Preferably, an LED warning light is provided on the outer side of the inflatable cushion, and the LED warning light is electrically connected to the main control unit.

[0014] Preferably, the surface layer has a plurality of air holes, and a miniature silent ventilation fan is installed in each air hole.

[0015] Preferably, a plurality of the air holes are arranged in an array on the surface, and the miniature silent ventilation fan is electrically connected to the main control unit.

[0016] Preferably, the material of the surface layer is any one of medical-grade oxygen-permeable mesh, high-molecular polyester fiber fabric, or knitted fabric.

[0017] Preferably, the surface layer is covered with a polyurethane waterproof fabric containing a nano-silver coating, and the polyurethane waterproof fabric is detachably connected to the surface layer.

[0018] The present invention adopts the above technical solution and has the following technical effects compared with the prior art:

[0019] (1) By setting up air chamber units, air pipelines and micro air pumps, the air chamber units are arranged in a honeycomb pattern. The micro air pumps and air pipelines are used to charge and release the air chamber units in a coordinated manner, so as to achieve dynamic adjustment of pressure distribution, avoid long-term local pressure, effectively reduce the risk of pressure ulcers, improve the patient's user experience, and solve the problem that medical mattresses cannot avoid continuous local pressure.

[0020] (2) Through the honeycomb arrangement of regular hexagonal air chamber units and parallel air pipelines, combined with the linkage of micro air pumps and solenoid valves, the air chamber pressure can be adjusted in real time to avoid local continuous pressure and effectively reduce the risk of pressure ulcers. The pressure sensor grid is connected to the main control unit signal, which can dynamically monitor the pressure distribution and automatically adjust the inflation and deflation to improve patient comfort.

[0021] (3) By embedding a flexible capacitive sensor and an impedance measurement electrode in the functional layer, using dual sensing technology of capacitance and impedance, the surface fabric is embedded with a flexible capacitive sensor to detect trace amounts of liquid on the surface, and the middle layer uses an impedance measurement electrode to distinguish between urine and feces.

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0033] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0034] Example 1:

[0035] Please see Figure 1-3 The dynamic pressure relief and intelligent monitoring multi-integrated mesh mattress in this embodiment includes a surface layer 100, a functional layer 200 and an inflatable pad body 300 connected from top to bottom, and a dynamic pressure relief component 400 is provided on the inflatable pad body 300.

[0036] The dynamic pressure reduction component 400 includes several air chamber units 401 and several air passage pipes 402 connected to the air chamber units 401. The air chamber units 401 are arranged in a honeycomb matrix. Several micro air pumps 403 are provided between the inflatable cushion body 300 and the air chamber units 401. The air passage pipes 402 are connected to the output end of the micro air pumps 403.

[0037] Specifically, the air chamber units 401 arranged in a honeycomb matrix are assisted in inflation and deflation by a micro air pump 403, which adjusts the air pressure of each air chamber unit 401 in real time, disperses the body pressure, and avoids local continuous pressure.

[0038] It should be noted that the noise level of the miniature air pump 403 is less than 30 decibels, which improves the quietness of the medical mattress.

[0039] In application, the air chamber units 401 are arranged in a regular hexagonal honeycomb matrix and interconnected through parallel air passages 402 to form a uniform support network. The micro air pump 403 provides the air chamber units 401 with the power to charge and discharge air. The air pressure of each air chamber unit 401 is adjusted through the air passages 402. The pressure change changes the stress point and avoids local continuous pressure.

[0040] Example 2:

[0041] The basic content is the same as in Example 1, except that:

[0042] Please see Figure 2-6 In this embodiment, the cross-sectional shape of the air chamber unit 401 is a regular hexagon. Adjacent air chamber units 401 are connected in parallel through air passage pipes 402. The air pressure balance is achieved through the parallel air passage pipes 402, which greatly reduces the standard deviation of the interface pressure.

[0043] The regular hexagonal honeycomb matrix, through the shared wall design of adjacent air chamber units 401, enables external pressure to be uniformly transmitted along the six sides to the surrounding six air chamber units 401, thereby reducing the standard deviation of interface pressure.

[0044] It should be noted that the hexagonal arrangement of the air chamber unit 401 improves the pressure dispersion efficiency, reduces the standard deviation of the interface pressure, and completely eliminates local high pressure points.

[0045] The inflatable cushion body 300 is equipped with a main control unit 404, and the air pipeline 402 is equipped with a solenoid valve 405. The solenoid valve 405 is electrically connected to the main control unit 404.

[0046] Furthermore, the solenoid valve 405 adopts PWM modulation technology and has high opening accuracy, ensuring precise control of air volume. Multiple independent air chamber units 402 form a biomimetic honeycomb structure, which alternately inflates and deflates to simulate manual turning over.

[0047] Specifically, by triggering a sequence of alternating inflation and deflation through a preset time interval, when one group of air chamber units 401 is inflated and raised to support, the adjacent group of air chamber units 401 automatically deflates to reduce pressure, forming a wave-like undulating motion pattern that continuously changes the body contact point. This periodic change mimics the physical action of manual turning over, forcibly shifting weight distribution and reducing continuous pressure on high-risk areas such as the sacrum and coccyx.

[0048] The pressure sensor grid 406 monitors the pressure inside the air chamber unit 401 in real time. The main control unit 404 controls the solenoid valve 405 to work in conjunction with the micro air pump 403 to release air from the high-pressure area and fill air into the low-pressure area, forming a closed-loop pressure balance.

[0049] It should be added that during CPR, one-click deflation and one-click setting to a rigid support state can quickly form a rigid support plane, which is convenient for operation during cardiopulmonary resuscitation and can also be adapted to examination environments such as MRI.

[0050] Furthermore, a plurality of pressure sensor grids 406 are equally spaced on the inner wall of the air chamber unit 401. The pressure sensor grids 406 are signal connected to the main control unit 404. The pressure sensor grids 406 adopt a distributed layout, which can capture the micro-pressure changes at various positions on the inner wall of the air chamber unit 401 in real time. The measurement accuracy can reach the micrometer level resolution. The grid design is suitable for monitoring the pressure gradient distribution in a closed space, providing multi-dimensional pressure data for the system.

[0051] During application, the pressure sensor grid 406 continuously collects patient body pressure distribution data, controls the opening of the solenoid valve 405 corresponding to the high-pressure area, releases the gas of the air chamber unit 401 through the micro air pump 403, reduces local pressure, and the adjacent air chamber units 401 are synchronously inflated to maintain the overall support force balance and prevent collapse. After adjustment, the pressure sensor grid 406 re-monitors, forming a closed-loop control.

[0052] Example 3:

[0053] The basic content is the same as in Example 1, except that:

[0054] Please see Figure 7-9 In this embodiment, the functional layer 200 includes a fabric layer 201 and a middle layer 202. The fabric layer 201 is located on the upper side of the middle layer 202. A flexible capacitive sensor 203 is embedded in the fabric layer 201. An impedance measurement electrode 204 is embedded in the middle layer 202. Both the flexible capacitive sensor 203 and the impedance measurement electrode 204 are signal connected to the main control unit 404.

[0055] It should be noted that dual-mode detection using a flexible capacitive sensor 203 and an impedance measurement electrode 204 can distinguish between urine and feces through liquid diffusion mode analysis. When the liquid is urine, it exhibits a low impedance characteristic, while when the liquid is feces, it exhibits a high impedance characteristic.

[0056] An LED warning light 301 is provided on the outside of the inflatable cushion 300, and the LED warning light 301 is electrically connected to the main control unit 404.

[0057] Specifically, when the impedance measuring electrode 204 detects a low impedance, the excrement is urine. The impedance measuring electrode 204 sends a signal to the main control unit 404. After receiving the signal, the main control unit 404 activates the LED warning light 301, which illuminates in yellow. When the impedance measuring electrode 204 detects a high impedance, the excrement is feces. The impedance measuring electrode 204 sends a signal to the main control unit 404. After receiving the signal, the main control unit 404 activates the LED warning light 301, which illuminates in red.

[0058] It should be added that the inflatable cushion body 300 is equipped with medical-grade Bluetooth, which is used to transmit the data detected by the impedance measurement electrode 204 to the nurse station for skin risk warning management.

[0059] This Bluetooth module is dedicated to transmitting physiological data collected by the impedance measurement electrode 204 to the central monitoring system at the nurse station, enabling real-time early warning and management of skin risks. The medical-grade Bluetooth uses the medical-grade Bluetooth 5.1 protocol compliant with the IEEE 11073 standard. The transmitted content includes: impedance measurement data, pressure distribution map of the pressure sensor grid 406, and excrement type identification results.

[0060] Several air holes 101 are provided on the surface layer 100, and a miniature silent ventilation fan 102 is installed in the air hole 101.

[0061] Several vents 101 are arrayed on the surface layer 100. The vents 101 are arranged in a regular matrix to ensure uniform airflow distribution. The honeycomb-shaped air chamber unit 401 and the vents 101 form a three-dimensional air duct to enhance air convection efficiency. The miniature silent ventilation fan 102 is electrically connected to the main control unit 404.

[0062] The material of the surface layer 100 is any one of medical-grade oxygen-permeable mesh, high-molecular polyester fiber fabric, or knitted fabric.

[0063] Specifically, medical-grade breathable mesh fabric is a medical-grade breathable material with high oxygen permeability and antibacterial properties, suitable for clinical scenarios requiring high breathability; high-molecular polyester fiber fabric has excellent abrasion resistance and tear resistance, is easy to clean and disinfect, and meets hospital infection control requirements; knitted fabric provides a soft touch, increases patient comfort, and its elastic structure adapts to different body types and pressure distributions.

[0064] Preferably, the surface layer 100 is made of medical-grade oxygen-permeable mesh fabric to improve the breathability of the medical mattress, and is combined with a miniature silent ventilation fan 102 to form air convection.

[0065] The surface layer 100 is covered with a polyurethane waterproof cloth containing a nano-silver coating. The polyurethane waterproof cloth is detachably connected to the surface layer 100. The nano-level zinc oxide coating has an antibacterial rate of ≥99% against Staphylococcus aureus, realizing intelligent regulation of the wound microenvironment and inhibiting bacterial growth. The synergistic effect of the nano-level zinc oxide coating and environmental regulation reduces the risk of infection.

[0066] In application, when excrement comes into contact with surface 100, flexible capacitive sensor 203 is activated. Flexible capacitive sensor 203 detects the diffusion range of the liquid. When impedance measuring electrode 204 detects low impedance, the excrement is urine. Impedance measuring electrode 204 sends a signal to main control unit 404. After receiving the signal, main control unit 404 activates LED warning light 301, which illuminates yellow. When impedance measuring electrode 204 detects high impedance, the excrement is feces. Impedance measuring electrode 204 sends a signal to main control unit 404. After receiving the signal, main control unit 404 activates LED warning light 301, which illuminates red.

[0067] In summary, combining Figures 1 to 9 As shown, the working principle of this multi-functional mesh mattress with dynamic pressure reduction and intelligent monitoring is as follows:

[0068] The pressure sensor grid 406 continuously collects patient body pressure distribution data, controls the opening of the solenoid valve 405 corresponding to the high-pressure area, releases the gas of the air chamber unit 401 through the micro air pump 403, reduces local pressure, and the adjacent air chamber units 401 are inflated synchronously to maintain the overall support force balance and prevent collapse. After adjustment, the pressure sensor grid 406 re-monitors to form a closed-loop control.

[0069] When excrement comes into contact with surface 100, flexible capacitive sensor 203 is activated. Flexible capacitive sensor 203 detects the diffusion range of the liquid. When impedance measuring electrode 204 detects low impedance, the excrement is urine. Impedance measuring electrode 204 sends a signal to main control unit 404. After receiving the signal, main control unit 404 activates LED warning light 301, which illuminates yellow. When impedance measuring electrode 204 detects high impedance, the excrement is feces. Impedance measuring electrode 204 sends a signal to main control unit 404. After receiving the signal, main control unit 404 activates LED warning light 301, which illuminates red.
