Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical and nursing facility technology, and in particular to an intelligent air mattress. Background Technology
[0002] With the aging population and the increasing demand for long-term bedridden patient care, intelligent medical care equipment is rapidly developing towards automation, precision, and humanization. Air mattresses, as core nursing equipment for preventing pressure ulcers and improving patient comfort, have evolved from traditional inflatable support structures to comprehensive systems integrating sensing monitoring and intelligent early warning functions.
[0003] However, existing air mattresses lack real-time dynamic monitoring of the pressure distribution on the patient's body surface in clinical use, making it difficult to accurately identify the duration of local pressure, resulting in delayed warning of pressure ulcer risk. For patients with indwelling urinary catheters, the urine bag is usually placed haphazardly on the bed, which is easily compressed, pulled, or even backflowed and contaminated, affecting the accuracy of urine measurement and increasing the risk of infection. Utility Model Content
[0004] This application provides an intelligent air mattress that solves the technical problems of existing air mattresses being unable to monitor the duration of local pressure and being prone to compression, traction, or even backflow contamination in patients with indwelling catheters, thus affecting the accuracy of urine measurement.
[0005] This application provides a smart air mattress, comprising: The bed body includes a contact layer, a buffer layer and a pressure sensing layer arranged sequentially from top to bottom, and the pressure sensing layer has a built-in sensor matrix. A urine bag placement area is provided on the bed frame and is located at a position slightly below the middle of the length of the bed frame. The urine bag placement area includes a base that covers the urine bag placement area.
[0006] In some embodiments, the urine bag placement area further includes an anti-pressure ring, which is fixedly disposed on the outer ring of the base, and the outer wall of the anti-pressure ring is a guide slope that slopes outward from top to bottom.
[0007] In some embodiments, the anti-pressure ring is made of ABS plastic or flexible TPU.
[0008] In some embodiments, a catheter fixing groove is provided on the side of the anti-pressure ring near the middle of the bed.
[0009] In some embodiments, there are two urine bag placement areas, located on both sides of the bed in the width direction.
[0010] In some embodiments, the smart air mattress further includes an alarm module and a control unit, both of which are electrically connected to the control unit.
[0011] In some embodiments, the alarm module includes a voice prompt unit and a warning light.
[0012] In some embodiments, the surface of the base is provided with a hydrophobic coating.
[0013] In some embodiments, the bed body is provided with a recess, the urine bag placement area is disposed in the recess and embedded in the recess, and the anti-pressure ring is provided with a cover plate, the cover plate being operable to open or close the anti-pressure ring port.
[0014] In some embodiments, the bottom surface of the cover plate is provided with a water-absorbing layer, and magnets are provided at the four corners of the water-absorbing layer. The magnets are magnetically attracted to the cover plate.
[0015] The beneficial effects of this application are as follows: The intelligent air mattress provided in this application, by setting a pressure sensing layer composed of a sensor matrix inside the mattress, can monitor the pressure distribution of various parts of the patient's body in contact with the air mattress in real time. Combined with the control unit, it can accurately time the pressure duration, effectively solving the problems of the inability to quantify the duration of local pressure and the lag in pressure ulcer warning in the prior art, and realizing early intelligent warning of pressure ulcer risk. At the same time, a dedicated urine bag placement area is set in the middle of the mattress, and the base is integrated with the pressure sensing layer. It can monitor the weight change of the urine bag in real time and accurately, avoiding discomfort to the patient due to the urine bag being too full.

Detailed Implementation
[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0020] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.
[0021] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.
[0022] This application provides an intelligent air mattress, which solves the technical problems in the prior art where air mattresses cannot monitor the duration of local pressure and are prone to compression, traction, or even backflow contamination in patients with indwelling catheters, affecting the accuracy of urine measurement.
[0023] The technical solution in this application is to solve the above-mentioned technical problems, and the general idea is as follows: like Figures 1-4As shown, this application provides an intelligent air mattress, including a mattress body and a urine bag placement area 40. The mattress body includes a contact layer 10, a buffer layer 20, and a pressure sensing layer 30 arranged sequentially from top to bottom. The contact layer 10 is made of a skin-friendly and breathable fabric material, the buffer layer 20 is made of high-resilience sponge or memory foam, and the pressure sensing layer 30 has a built-in sensor matrix composed of multiple miniature piezoresistive pressure sensors. The urine bag placement area 40 is located on the mattress body, specifically, in the lower middle part of the mattress body along its length, close to the patient's legs, to facilitate natural drainage of the catheter and prevent backflow. The urine bag placement area 40 includes a base 41, which is made of rigid ABS plastic. The base 41 covers the urine bag placement area 40 and is generally rectangular in shape with anti-slip texture on the inner surface for stable placement of the urine bag. The surface of the base 41 is provided with a hydrophobic coating, which is a perfluoropolyether-based nano-coating or a silica nano-hydrophobic coating. It is uniformly coated on the surface of the base 41 by spraying or dipping and then cured at low temperature. This coating can effectively reduce the adhesion of urine, cleaning fluid and other liquids to the surface of the base 41, making it less likely for liquids to remain and easier to pour and clean.
[0024] In actual installation, the urine bag placement area 40 can be directly set on the contact layer 10, and the base 41 can be fixedly connected to the contact layer 10; alternatively, the contact layer 10 and buffer layer 20 corresponding to the urine bag placement area 40 can be removed, and the base 41 can be directly fixedly connected to the pressure sensing layer 30 to improve the accuracy and stability of weighing detection.
[0025] The pressure sensor layer 30 monitors the pressure distribution of different parts of the patient's body in contact with the air mattress in real time. Combined with the control unit 52, the pressure duration is accurately timed, which effectively solves the problems of the inability to quantify the duration of local pressure and the lag in pressure ulcer warning in the existing technology. A dedicated urine bag placement area 40 is set in the middle of the bed, and the base 41 is integrated with the pressure sensor layer 30. The weight change of the urine bag can be monitored in real time and accurately, realizing independent and accurate measurement of the urine bag weight. This allows for timely treatment of the urine in the urine bag and avoids discomfort to the patient due to the urine bag being too full. It significantly improves the accuracy and safety of urine measurement for patients with indwelling catheters.
[0026] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
[0027] Preferably, the urine bag placement area 40 further includes an anti-pressure ring 42, which is fixedly disposed on the outer ring of the base 41 and integrally formed or snapped with the base 41. The outer wall of the anti-pressure ring 42 is a guide slope that slopes outward from top to bottom, with an inclination angle of 15° to 30°, forming a protective structure similar to a "trumpet mouth". The anti-pressure ring 42 is made of ABS plastic with a smooth surface, making it easy to clean and disinfect. Alternatively, the anti-pressure ring 42 may be made of flexible TPU, which has both elasticity and impact resistance, improving the comfort of the patient's limbs when touched. The inner cavity of the anti-pressure ring 42 forms a receiving space for the stable placement of the urine bag, and its height design effectively prevents the patient's legs or buttocks from directly pressing on the urine bag during turning over.
[0028] Furthermore, the anti-pressure ring 42 is provided with a urinary catheter fixing groove 43 on the side near the middle of the bed, which can effectively limit and fix the urinary catheter after it is led out from the proximal end of the patient's body, preventing the urinary catheter from being pulled, twisted, kinked or dislodged due to the patient's movement or turning over, and ensuring the continuous unobstructed flow of urine.
[0029] Preferably, there are two urine bag placement areas 40, located on both sides of the bed width, allowing for flexible placement of the urine bag on both sides. This effectively adapts to the clinical needs of patients in different positions or during frequent turning. When the patient lies on one side, the urine bag can be placed in the opposite urine bag placement area 40, preventing the urine bag from being directly compressed by the body or sandwiched between the body and the bed surface. This ensures smooth urine drainage, prevents backflow and contamination, and ensures the measurement accuracy of the weight sensor is not interfered with. The dual-sided arrangement also improves the convenience of nursing operations, allowing nurses to quickly select the nearest placement area based on the catheter's exit direction and the patient's position, reducing the risk of tubing traction.
[0030] The intelligent air mattress also includes an alarm module 51 and a control unit 52. The alarm module 51 and the sensor matrix are both electrically connected to the control unit 52. The alarm module 51 includes a voice prompt unit and a warning light.
[0031] The control unit 52 combines the pressure data from the sensor matrix with the time relay logic to accurately identify the duration of pressure. The control unit 52 has built-in pressure thresholds and time thresholds. When the sensor in a certain area continuously detects that the pressure exceeds the threshold and the cumulative time reaches the limit, the alarm module 51 is automatically triggered to start voice broadcast and LED flashing until manual confirmation or pressure is released, effectively avoiding the problem of pressure sores caused by excessive local pressure duration.
[0032] Preferred, such as Figure 4As shown, the bed body is provided with a recessed portion 60, and the urine bag placement area 40 is disposed in the recessed portion 60. The recessed portion 60 penetrates the contact layer 10 and the buffer layer 20, and a local area of the pressure sensing layer 30 is exposed at its bottom. The urine bag placement area 40 is embedded in the recessed portion 60. A cover plate 44 is provided on the anti-pressure ring 42, and the cover plate 44 can be operably opened or closed at the port of the anti-pressure ring 42.
[0033] Furthermore, the bottom surface of the cover plate 44 is provided with an absorbent layer 45, which can be a polymer absorbent cotton pad for absorbing accidentally spilled urine or cleaning residue. Magnets 46 are provided at the four corners of the absorbent layer 45, and the magnets 46 are magnetically attracted to the cover plate 44. Iron sheets or reverse magnets 46 are provided at corresponding positions on the cover plate 44. The absorbent layer 45 can be detachably fixed by magnetic attraction, making it easy to replace or clean.
[0034] By incorporating a recessed portion 60 into the bed frame and embedding the urine bag placement area 40 within it, the urine bag is positioned lower than the bed surface, further reducing the risk of accidental pressure on the urine bag by the patient's limbs when turning over, thus improving safety and comfort. An anti-pressure ring 42 is fixedly connected to the port of the recessed portion 60, forming a stable and reliable protective structure. Combined with the inclined outer wall, this allows for automatic limb guidance. An openable cover 44 is provided, which can close the port of the anti-pressure ring 42 when the urine bag is not in use, preventing dust, liquid, or foreign objects from falling into the base 41 and pressure sensor area, maintaining internal cleanliness, and avoiding patient embarrassment. The bottom of the cover 44 features a magnetically secured absorbent layer 45, which quickly absorbs spilled liquid, preventing leakage into the sensor or bed frame, and offering advantages such as stain resistance, moisture resistance, and easy maintenance.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.
[0036] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
