Description

Technical Field

[0001] This application relates to the field of pressure-reducing pad technology, specifically a pressure-reducing pad for prone ventilation. Background Technology

[0002] The prone ventilation decompression mattress is a crucial auxiliary device in intensive care medicine, primarily used for critically ill patients with acute respiratory distress syndrome (ARDS) and other conditions requiring prone ventilation. Its core objective is to effectively distribute pressure on key bony prominences during prolonged prone positioning, preventing pressure sores (bedsores), while maintaining patient stability and comfort, and ensuring unimpeded access to treatment procedures (such as endotracheal intubation and central venous catheterization). Clinical statistics show that the accidental dislodgement rate of breathing tubes due to mattress displacement during the transport of critically ill patients is as high as 12% (Chinese Journal of Critical Care Medicine, 2023). Existing decompression mattresses lack a lumen fixation structure and rely solely on adhesive tape, making them prone to loosening during transport.

[0003] The existing prone ventilation-specific decompression mats are mainly used for critically ill patients who need to maintain oxygen supply through a breathing tube. During the transport of critically ill patients, the decompression mat needs to be lifted and moved, which may cause the breathing tube to loosen and fall off, affecting the patient and making it inconvenient to use.

[0004] Therefore, this application provides a pressure-reducing mat specifically for prone ventilation to solve the above problems. Utility Model Content

[0005] This application provides a pressure-reducing pad specifically for prone ventilation, aiming to solve the problem mentioned in the background art that the existing pressure-reducing pads for prone ventilation are mainly used for critically ill patients who need to maintain oxygen supply through a breathing tube. During the transportation of critically ill patients, the pressure-reducing pad needs to be lifted and moved, which may cause the breathing tube to loosen and fall off, affecting the patient and causing inconvenience in use.

[0006] To achieve the above objectives, this application provides the following technical solution: a pressure-reducing pad for prone ventilation, wherein the pressure-reducing pad for prone ventilation includes an air cushion mechanism;

[0007] To address the issue that existing prone ventilation-specific decompression mattresses primarily serve critically ill patients who require oxygenation via breathing tubes, and that lifting and moving the mattress during transport can cause the breathing tube to loosen and fall out, impacting the patient and causing inconvenience, the proposed air mattress mechanism includes a decompression mattress body. One end of the body is connected to a headrest. Both sides of the headrest have ventilation grooves, with a fixed base block fixedly connected inside each groove. Sliding grooves are formed on both sides of each groove, with guide rods fixedly connected inside. Connecting blocks and springs are located outside the guide rods. A fixed top block is fixedly connected to the bottom block, and the fixed top block is positioned above the bottom block. Sliding the fixed top block causes it to slide against the outside of the guide rod, compressing the spring on its side. This places the breathing tube inside the bottom block. Releasing the fixed top block causes the connecting block to rebound under the spring's force, moving the fixed top block in the opposite direction to the top of the bottom block. The silicone pads inside the fixed bottom and fixed top blocks increase the friction between the breathing tube and the tube. This facilitates the secure fixing of the breathing tube during the transport of critically ill patients, preventing it from loosening and falling off. The operation is simple, quick, and convenient.

[0008] Preferably, to address the issue of convenient use of the connecting block, a limiting rod is fixedly connected inside the sliding groove, the connecting block is disposed outside the limiting rod, and the connecting block is slidably connected to the limiting rod. The spring is fixedly connected between the inside of the sliding groove and the top of the connecting block. The limiting rod enhances the stability of the connecting block's movement. During the movement of the connecting block, the spring on the side is compressed, allowing the connecting block to return to its original shape.

[0009] Preferably, in order to solve the problem of stable fixation of the breathing tube, the fixing bottom block and the fixing top block are symmetrically arranged, and multiple sets of silicone pads are provided inside the opposite side of the fixing bottom block and the fixing top block. The multiple sets of silicone pads inside the fixing bottom block and the fixing top block can increase the friction with the breathing tube, making it convenient to use.

[0010] Preferably, to solve the problem of conveniently fixing the breathing tube, the bottom of the fixing top block is fixedly connected to multiple sets of plug-in blocks, and the top of the fixing bottom block is provided with plug-in slots that are adapted to the plug-in blocks. The plug-in blocks are plugged into the plug-in slots, and the friction generated between the plug-in blocks and the plug-in slots can fix the fixing top block and the fixing bottom block, thereby facilitating the fixing of the breathing tube inside the fixing bottom block and the fixing top block, making it convenient to use.

[0011] Preferably, to address the issue of convenient cleaning, the top of the pressure-reducing pad body is provided with multiple sets of supporting soft pads, and an antibacterial cotton pad is provided on the top of the pressure-reducing pad body. The antibacterial cotton pad is adapted to the supporting soft pads, and the two ends of the antibacterial cotton pad are fixedly connected with Velcro hooks. The two ends of the pressure-reducing pad body are provided with Velcro loops. The Velcro hooks and loops are bonded together. The antibacterial cotton pad is placed over the supporting soft pads on the top of the pressure-reducing pad body, and the Velcro hooks at both ends of the antibacterial cotton pad are bonded to the Velcro loops at both ends of the pressure-reducing pad body. This fixes the antibacterial cotton pad to the outside of the pressure-reducing pad body and the supporting soft pads, thereby ensuring the cleanliness of the pressure-reducing pad body and facilitating the disassembly and cleaning of the antibacterial cotton pad. It is convenient to clean, simple and quick to operate, and easy to use.

[0012] Preferably, in order to solve the problem of convenient inflation, an inflation tube is provided on one side of the main body of the pressure-reducing pad, and a control valve is provided inside the inflation tube. The main body of the pressure-reducing pad can be easily inflated through the inflation tube, thus making it convenient to use.

[0013] This air cushion mechanism features a sliding fixed top block. Force applied to the top block causes the connecting block to slide outside the guide rod, compressing a spring on its side. This places the breathing tube inside the fixed bottom block. Releasing the top block causes the connecting block to rebound under the spring's force, moving the top block in the opposite direction to the top of the fixed bottom block. The silicone pads inside the top and bottom blocks increase friction with the breathing tube, facilitating easy fixation of the breathing tube during transport of critically ill patients and preventing it from loosening or falling out. The mechanism is simple, quick, and easy to use.

[0014] This air cushion mechanism places an antibacterial cotton pad over the supporting soft pad on top of the pressure-reducing pad body. The antibacterial cotton pad is attached to the inside of the pressure-reducing pad body by Velcro hooks at both ends of the antibacterial cotton pad and Velcro loops at both ends of the pressure-reducing pad body. This secures the antibacterial cotton pad to the outside of the pressure-reducing pad body and the supporting soft pad, ensuring the cleanliness of the pressure-reducing pad body and facilitating the disassembly and cleaning of the antibacterial cotton pad. It is easy to clean, simple and quick to operate, and convenient to use. Attached Figure Description

[0021] 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 some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] Example 1

[0023] This embodiment provides a pressure-reducing mat specifically for prone ventilation, such as... Figure 1-4 As shown, the prone ventilation-specific pressure relief mat includes an air cushion mechanism 1.

[0024] The air cushion mechanism 1 makes it easy to secure the breathing tube during the transport of critically ill patients, preventing the breathing tube from becoming loose and falling off. It is simple, quick, and convenient to use.

[0025] Specifically, the air cushion mechanism 1 includes a pressure-reducing pad body 11, one end of which is connected to a head pad 12. The head pad 12 has ventilation grooves 13 on both sides. A fixed bottom block 14 is fixedly connected inside the ventilation grooves 13. Sliding grooves 15 are opened on both sides of the ventilation grooves 13. A guide rod 16 is fixedly connected inside the sliding grooves 15. A connecting block 17 is provided outside the guide rod 16. A spring 18 is provided outside the guide rod 16. A fixed top block 20 is fixedly connected between the connecting blocks 17. The fixed top block 20 is located above the fixed bottom block 14.

[0026] In use, the fixed top block 20 is slidable, causing the connecting block 17 to slide outside the guide rod 16 under the force of the fixed top block 20. This causes the connecting block 17 to compress the spring 18 on its side, placing the breathing tube inside the fixed bottom block 14. When the fixed top block 20 is released, the connecting block 17 is subjected to the rebound force of the spring 18, causing the connecting block 17 to move the fixed top block 20 in the opposite direction to the top of the fixed bottom block 14. The silicone pad 21 inside the fixed bottom block 14 and the fixed top block 20 increases the friction between the breathing tube and the tube. This facilitates the fixation of the breathing tube during the transport of critically ill patients, preventing the breathing tube from loosening and falling off. The operation is simple, quick, and convenient. The silicone pad 21 has a Shore hardness of 20A to 30A (optimal value 25A), a surface texture of a diamond-shaped raised array (raised height 0.5mm ± 0.1mm), and a coefficient of friction of ≥0.8.

[0027] Furthermore, a limiting rod 19 is fixedly connected inside the sliding groove 15, and a connecting block 17 is disposed outside the limiting rod 19, with the connecting block 17 slidably connected to the limiting rod 19. A spring 18 is fixedly connected between the inside of the sliding groove 15 and the top of the connecting block 17, with the connecting block 17 slidably connected to the limiting rod 19. The limiting rod 19 enhances the stability of the movement of the connecting block 17. During the movement of the connecting block 17, the spring 18 disposed on the side is compressed, allowing the connecting block 17 to return to its original shape. The elastic coefficient of the spring 18 is 1.2 N / mm-1.8 N / mm, and the compression stroke is 15 mm to 20 mm.

[0028] Furthermore, the fixed base block 14 and the fixed top block 20 are symmetrically arranged, and multiple sets of silicone pads 21 are provided inside the fixed base block 14 and the fixed top block 20 on opposite sides. The multiple sets of silicone pads 21 provided inside the fixed base block 14 and the fixed top block 20 can increase the friction with the breathing tube, making it convenient to use.

[0029] The bottom of the fixed top block 20 is fixedly connected to multiple sets of plug-in blocks 22. The top of the fixed bottom block 14 is provided with a plug-in groove 23 that is adapted to the plug-in block 22. The plug-in block 22 is plugged into the plug-in groove 23. The friction between the plug-in block 22 and the plug-in groove 23 can fix the fixed top block 20 and the fixed bottom block 14, thereby facilitating the fixing of the breathing tube inside the fixed bottom block 14 and the fixed top block 20, making it convenient to use.

[0030] Example 2

[0031] Unlike Embodiment 1, to address the issue of easy cleaning, the top of the pressure-reducing pad body 11 is provided with multiple sets of supporting soft pads 24, and an antibacterial cotton pad 25 is provided on the top of the pressure-reducing pad body 11. The antibacterial cotton pad 25 is adapted to the supporting soft pads 24, and the two ends of the antibacterial cotton pad 25 are fixedly connected with Velcro hooks 26. The two ends of the pressure-reducing pad body 11 are provided with Velcro loops 27, and the Velcro hooks 26 and Velcro loops 27 are bonded together. In use, the antibacterial cotton pad 25 is placed on the outside of the supporting soft pads 24 on the top of the pressure-reducing pad body 11, and the Velcro hooks 26 at both ends of the antibacterial cotton pad 25 are bonded to the Velcro loops 27 at both ends of the pressure-reducing pad body 11. This fixes the antibacterial cotton pad 25 to the outside of the pressure-reducing pad body 11 and the supporting soft pads 24, thereby ensuring the cleanliness of the pressure-reducing pad body 11 and facilitating the disassembly and cleaning of the antibacterial cotton pad 25. The operation is simple and quick, and the pad is easy to use.

[0032] Antibacterial cotton pad 25: Antibacterial rate ≥99% (according to ISO 20743 standard, against Staphylococcus aureus and Escherichia coli). Material structure: Surface layer: Polyester fiber antibacterial coating (containing nano silver ions); Inner core: Moisture-permeable polyurethane foam (density 45kg / m³). 3 Hook and loop fastener strength: peel force ≥ 0.6 N / cm.

[0033] Specifically, an inflation tube 28 is provided on one side of the pressure-reducing pad body 11. A control valve is provided inside the inflation tube 28. The pressure-reducing pad body 11 can be easily inflated through the inflation tube 28, thus facilitating its use. The air pressure threshold is ≤25kPa, and the overpressure is automatically released. The pressure holding performance of the air pad body 11 is <10% pressure drop in 24 hours.

[0034] The above are merely preferred embodiments of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
