Description

Technical Field

[0001] This utility model relates to the field of mattress technology, specifically an inflatable anti-bedsore mattress. Background Technology

[0002] Pressure ulcers are caused by prolonged pressure on localized tissues, leading to impaired blood circulation, tissue ischemia, and hypoxia, resulting in damage to the skin and subcutaneous tissues. Symptoms range from redness and induration to ulceration and necrosis. A mattress is an item that sits between the body and the bed. Inflatable pressure ulcer mattresses are specifically designed for people who are bedridden or sedentary for extended periods. They use air chambers to inflate and deflate, distributing or alternating pressure to prevent and alleviate pressure ulcers. However, existing inflatable mattresses are prone to contamination when used by bedridden patients due to prolonged bed rest. Cleaning requires completely removing the inflatable mattress. Air mattresses can only be cleaned after being removed, which is inconvenient for bedridden patients who cannot get up. However, an inflatable anti-decubitus mattress with the announcement number CN220459530U has multiple inflatable pads that can be installed on the base. The inflatable pads are connected to the air pipe at the output end of the air pump through air inlet pipes. The cover cloth on the outer wall of the inflatable pad can cover the upper surface of the base. Therefore, when an inflatable pad or cover cloth is soiled by a bedridden patient, the inflatable pad can be removed separately for cleaning and treatment, ensuring overall cleanliness and making it convenient for bedridden patients to use.

[0003] While the aforementioned technology allows for the separate disassembly of the air mattress for easy cleaning and handling, it suffers from the inability to quickly replace the connecting tubes. The corresponding module's air chamber may leak and fail to maintain the set pressure, resulting in insufficient support in the area. To prevent air leakage from affecting the patient's pressure, caregivers need to stop using the corresponding module or even the entire mattress and have the patient temporarily moved to the bed, which not only increases the workload of turning over and moving the patient. Utility Model Content

[0004] The purpose of this invention is to provide an inflatable anti-bedsore mattress to solve the problem mentioned in the background art that current mattresses on the market cannot quickly replace the connecting tubes.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an inflatable anti-decubitus mattress, comprising a row of inflatable pads, one end of each row of inflatable pads being connected to a connecting tube, the end of the connecting tube away from the inflatable pad being connected to an air pump, clamping rings being provided above and below each row of connecting tubes, one side of each row of clamping rings being slidably connected to one side of each row of inflatable pads, support plates being provided on both sides of the clamping rings, a hollow block being provided on the top of the lower support plate, the hollow block being slidably connected to the inside of the upper support plate, and limit blocks being slidably connected to both ends inside the hollow block, a detection component for leak detection of the connecting tubes being provided on the clamping rings, and a connecting component for connecting the inflatable pads being provided between the inflatable pads.

[0006] Preferably, the detection assembly includes two rows of detection elements respectively disposed on one side of two rows of clamping rings, and the outer surface of both rows of detection elements is provided with an isolation layer.

[0007] Preferably, the connecting assembly includes limiting plates disposed at both ends of one side of the inflatable pad, and limiting inserts disposed at both ends of the other side of the inflatable pad. The limiting inserts are slidably connected inside the limiting plates, and a protrusion is disposed on one side of the limiting insert, the protrusion being slidably connected inside the limiting plates.

[0008] Preferably, both ends of the limiting plate are provided with female hook and loop fasteners, the top of the limiting plate movably abuts against the limiting member, and both ends of the limiting member are provided with male hook and loop fasteners, and the male hook and loop fasteners and female hook and loop fasteners are attached to each other.

[0009] Preferably, the protrusions are all made of elastic material and are distributed at an angle equal to the center point of the limiting insert.

[0010] Preferably, the hollow block has a partition inside, one end of the limiting block is provided with an airbag between it and the partition, and a sealing ring is provided between the clamping ring and the connecting pipe, with the inner side of the sealing ring and the outer surface of the connecting pipe in contact with each other.

[0011] Preferably, the detection element is made of high-density hydrophilic sponge, and the isolation layer is made of polytetrafluoroethylene-coated nonwoven fabric.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: By moving the clamping rings closer together or further apart, the connecting tubes can be quickly disassembled and reassembled. When replacing the tubes, there is no need to completely disassemble the mattress module or transfer the patient, thus avoiding interruption of local pressure due to replacement and reducing the risk of pressure ulcer progression.

[0013] The detection components enable leak detection of the connecting pipe, allowing for timely detection and handling of leaks. This maintains the air chamber pressure at a safe threshold, preventing continuous pressure on high-risk areas and thus preventing the occurrence or progression of bedsores caused by leaks.

[0014] The connecting components allow for the assembly and disassembly of air mattresses, enabling the individual removal of soiled or malfunctioning mattresses without the need to move the entire mattress. This significantly reduces the time required for cleaning, repairing, or replacing individual modules without affecting the normal operation of other air mattresses. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] This utility model provides the following technical solution: an inflatable anti-bedsore mattress. Example 1: To solve the problem of existing mattresses not being able to quickly replace the connecting tube 2, the following is disclosed: a row of inflatable mattresses 1, one end of each row of inflatable mattresses 1 is connected to a connecting tube 2, and the end of the connecting tube 2 away from the inflatable mattress 1 is connected to an air pump 3 (e.g., Figure 1 , Figure 2 and Figure 4 As shown), it is used to inflate the air pad 1. A row of connecting tubes 2 has clamping rings 4 above and below it. One side of each row of clamping rings 4 is slidably connected to one side of the row of air pads 1. Support plates 5 are provided on both sides of the clamping rings 4. A hollow block 6 is provided at the top of the lower support plate 5. The hollow block 6 is slidably connected inside the upper support plate 5. Limiting blocks 7 (such as...) are slidably connected to both ends inside the hollow block 6. Figure 6As shown), the clamping ring 4 is equipped with a detection assembly for leak detection of the connecting pipe 2. The detection assembly includes two rows of detection elements 10 respectively disposed on one side of the two rows of clamping rings 4 for detecting the connecting pipe 2. The outer surface of both rows of detection elements 10 is provided with an isolation layer 11. A partition is provided inside the hollow block 6. An airbag 8 is provided between one end of the limiting block 7 and the partition. A sealing ring 9 is provided between the clamping ring 4 and the connecting pipe 2. The inner side of the sealing ring 9 and the outer surface of the connecting pipe 2 are in contact with each other (e.g., Figure 6 As shown), the test piece 10 is made of high-density hydrophilic sponge, and the isolation layer 11 is made of polytetrafluoroethylene coated non-woven fabric.

[0019] First, connect one end of the connecting pipe 2 to the output end of the air pump 3. Then, place the other end of the connecting pipe 2 onto the interface of the air pad 1. Next, push the clamping rings 4 closer together. When the clamping rings 4 are close together, press the limiting block 7 to make it slide inside the hollow block 6 and squeeze the airbag 8 inside, causing the airbag 8 to deform. After the hollow block 6 passes through the support plate 5, the limiting block 7 will reset under the action of the airbag 8 (e.g., Figure 6 As shown), this limits the two support plates 5, thereby limiting the clamping ring 4 and fixing the connecting pipe 2. When the clamping ring 4 approaches, it also drives the sealing ring 9 to approach the connecting pipe 2. Subsequently, the sealing ring 9 and the connecting pipe 2 fit together to seal them. When the connecting pipe 2 needs to be replaced, the limiting block 7 can be pressed to make it slide again inside the hollow block 6, so that the hollow block 6 can slide inside the support plate 5. When the clamping rings 4 approach each other, they also drive the detection element 10 to approach each other. The detection element 10 is pre-soaked in a gas-sensitive color-changing indicator (such as...). Figure 6 As shown), under normal ventilation, there is no leakage in the connecting pipe 2, and the detection element 10 retains its initial color without local discoloration. If there is a micro-leak or obvious leak in the connecting pipe 2, the leaking airflow will enter the detection element 10, causing the indicator to change color. A noticeable discoloration spot will appear on the detection element 10 at the corresponding location of the leak, achieving real-time monitoring and precise location of the leak. The detection element 10, made of high-density hydrophilic sponge, can absorb and store the indicator, while the isolation layer 11, made of polytetrafluoroethylene-coated non-woven fabric, prevents external dust and moisture from entering the detection element 10 and does not affect the observation of the detection element 10 (e.g., Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown in the figure, when in use, the air pump 3 can be started, and then the air pad 1 will be inflated under the action of the connecting pipe 2. Pressure can be distributed or alternated by inflation and deflation to prevent and reduce bedsores.

[0020] Example 2: Unlike Example 1, the connecting component serves to connect the inflatable pads 1. It discloses that a connecting component is provided between the inflatable pads 1, and the connecting component includes limiting plates 12 (e.g., at both ends of one side of the inflatable pad 1) at both ends. Figure 3 and Figure 5 As shown), both ends of the inflatable cushion 1 on the other side are provided with limiting plates 13, which are slidably connected to the inside of the limiting plate 12. One side of the limiting plate 13 is provided with a protrusion 14, which is slidably connected to the inside of the limiting plate 12. Both ends of the limiting plate 12 are provided with female hook and loop fasteners 15. The top of the limiting plate 12 movably abuts against the limiting member 16. Both ends of the limiting member 16 are provided with male hook and loop fasteners 17, and the male hook and loop fasteners 17 and the female hook and loop fasteners 15 are mutually attached (e.g., ...). Figure 3 and Figure 5 As shown), it is used to fix the limiting member 16, thereby limiting the limiting plate 13. The protrusions 14 are all made of elastic material and are distributed at the same angle as the center point of the limiting plate 13.

[0021] When it is necessary to connect the inflatable pad 1, the limiting plate 13 can be inserted into the limiting plate 12, and then the protrusion 14 reaches the inside of the limiting plate 12 (e.g., Figure 3 As shown), the initial positioning is completed. The elastic protrusion 14 can be made of rubber, which allows it to smoothly enter the interior of the limiting plate 12 and increases friction. After the limiting insert 13 enters the limiting plate 12, the limiting member 16 can be brought close to the limiting plate 12 (as shown). Figure 1 , Figure 3 and Figure 5 As shown), the limiting member 16 then moves the male hook and loop fastener 17 closer to the female hook and loop fastener 15, so that it further limits the limiting insert plate 13, thereby realizing the connection between the inflatable pads 1.
