Description

Technical Field

[0001] This utility model relates to the field of human daily necessities, and more particularly to medical assistive devices, especially an air mattress that can assist patients in turning over. Background Technology

[0002] Air mattresses are often used in clinical practice for patients with low self-care ability who are unable to turn over independently, in order to relieve local pressure. During use, nursing staff are still needed to assist patients in turning over to avoid prolonged pressure on the same area and to prevent pressure injuries.

[0003] In the prior art, utility model patent CN212186972U discloses a novel pressure ulcer prevention and turning air mattress. This mattress consists of two inflatable turning air mattress bodies fused together; simply inflating the mattress allows for turning without external force. However, when the air mattress is inflated, the air pump compresses the air, causing the air entering the mattress to heat up. Furthermore, due to the influence of weather conditions and the patient's own body temperature, air is a poor conductor of heat and does not dissipate heat easily, affecting the patient's comfort. Summary of the Invention

[0004] The purpose of this invention is to provide an air mattress that can assist patients in turning over. This air mattress aims to solve the technical problem in the prior art where the temperature rise of the air mattress affects the patient's comfort.

[0005] This utility model discloses an air cushion that assists patients in turning over, comprising a bed board, an air cushion layer, an air pump, and a mounting shell. The air cushion layer is positioned above the bed board, and a first air cushion body and a second air cushion body are respectively disposed on the left and right sides of the upper surface of the air cushion layer. The output end of the air pump is connected to one end of the mounting shell via an air supply pipe. The other end of the mounting shell is provided with a conical shell. At least one inner wall of the mounting shell is provided with a cooling fin. The conical shell is connected to one end of a first connecting pipe, and the other end of the first connecting pipe is connected to a second connecting pipe and a third connecting pipe. The second connecting pipe is connected to the first air cushion body, and the third connecting pipe is connected to the second air cushion body. A first valve is disposed in the second connecting pipe, and a second valve is disposed in the third connecting pipe.

[0006] Furthermore, the upward-facing sides of the first and second air cushions form opposing slopes after inflation.

[0007] Furthermore, two symmetrical L-shaped limiting blocks are fixedly installed on one side of the bed board, and a base is installed on one side of the air pump, with the base positioned between the two limiting blocks.

[0008] Furthermore, a plug-in block is movably disposed within the upper limiting block, a positioning groove is provided on one side of the base, the bottom of the plug-in block passes through the limiting block and is inserted into the positioning groove, and a pull plate is provided on the top of the plug-in block.

[0009] Furthermore, the top of the upper limiting block is provided with two guide rods, and a spring is sleeved on the outside of each of the guide rods. The plug block is L-shaped, and one side of the plug block is sleeved on the outside of the two guide rods. The spring biases the plug block downward.

[0010] Furthermore, the mounting shell and the limiting block are mounted on the same side of the bed board.

[0011] Compared with existing technologies, the advantages of this invention are positive and significant. This invention incorporates cooling elements on the inner wall of the mounting shell. These elements cool the air output by the air pump, allowing the appropriately heated air to be alternately injected into the first and second air cushions. This assists the patient in turning over, prevents pressure injuries, and effectively improves patient comfort. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this does not limit the present invention.

[0019] like Figures 1-5As shown, this utility model discloses an air mattress that assists in turning over, comprising a bed board 1, an air cushion layer 2, an air pump 10, and a mounting shell 13. The air cushion layer 2 is disposed above the bed board 1. A first air cushion body 3 and a second air cushion body 4 are respectively disposed on the left and right sides of the upper surface of the air cushion layer 2. The output end of the air pump 10 is connected to one end of the mounting shell 13 through an air supply pipe 12. A conical shell 15 is disposed at the other end of the mounting shell 13. At least one inner wall of the mounting shell 13 is provided with a cooling fin 14. The conical shell 15 is connected to one end of a first connecting pipe 16. The other end of the first connecting pipe 16 is connected to a second connecting pipe 17 and a third connecting pipe 19. The second connecting pipe 17 is connected to the first air cushion body 3, and the third connecting pipe 19 is connected to the second air cushion body 4. A first valve 18 is disposed in the second connecting pipe 17, and a second valve 20 is disposed in the third connecting pipe 19.

[0020] Furthermore, the upward-facing sides of the first air cushion 3 and the second air cushion 4 form opposing slopes after inflation.

[0021] Furthermore, two symmetrical L-shaped limiting blocks 5 are fixedly installed on one side of the bed board 1, and a base 101 is installed on one side of the air pump 10, with the base 101 positioned between the two limiting blocks 5.

[0022] Furthermore, a plug-in block 8 is movably disposed within the upper limiting block 5, and a positioning groove 11 is provided on one side of the base 101. The bottom of the plug-in block 8 passes through the limiting block 5 and is inserted into the positioning groove 11. A pull plate 9 is provided on the top of the plug-in block 8.

[0023] Furthermore, the top of the upper limiting block 5 is provided with two guide rods 6, and a spring 7 is sleeved on the outside of each of the guide rods 6. The plug block 8 is L-shaped, and one side of the plug block 8 is sleeved on the outside of the two guide rods 6. The spring 7 biases the plug block 8 downward.

[0024] Furthermore, the mounting shell 13 and the limiting block 5 are mounted on the same side of the bed board 1.

[0025] When this utility model is in use, the bed body 1 serves as the main support plate to support the air cushion layer 2. The air cushion layer 2 is filled with air to support the patient. The first air cushion body 3 and the second air cushion body 4 are independent air cushion bodies from the air cushion layer 2. The first valve 18 and the second valve 20 control the second connecting pipe 17 and the third connecting pipe 19 to alternately inflate or deflate the first air cushion body 3 and the second air cushion body 4. The slope faces the patient and provides tilted support, which can assist the patient in turning over and prevent the patient from suffering pressure injuries.

[0026] The output end of the air pump 10 is connected to the mounting shell 13 via the air supply pipe 12. The cooling element 14, also called a thermoelectric cooling element or a semiconductor cooling element, is a device that uses the Peltier effect of semiconductor materials to achieve cooling. When current passes through a couple composed of two different conductors, heat is absorbed and released at the two ends of the couple, thereby achieving the purpose of cooling. When the air pump 10 is running, the externally pressurized air can be input into the mounting shell 13 through the air supply pipe 12. After the air is cooled by the cooling element 14 in the mounting shell 13, it enters the first connecting pipe 16 through the conical shell 15. Then, under the control of the first valve 18 and the second valve 20, the air at a suitable temperature is alternately input into the first air cushion 3 and the second air cushion 4 to prevent the air cushion temperature from rising and improve the patient's comfort.

[0027] One end of the L-shaped limiting block 5 is fixedly connected to the bed board 1, and the other end is stuck on the front side of the upper and lower edges of the air pump 10. When the insertion block 8 is not inserted into the groove 11, the air pump 10 can move laterally between the two limiting blocks 5. Before the base 101 of the air pump 10 is positioned in the two limiting blocks 5, the pulling plate 9 needs to be pulled to make the insertion block 8 move upward inside the limiting block 5. At this time, the insertion block 8 moves upward under the guidance of the two guide rods 6 to compress the spring 7. Then, the positioning groove 11 opened at the top of the base 101 is moved to the bottom of the insertion block 8. The elasticity of the spring 7 pushes the insertion block 8 downward to insert the insertion block 8 into the positioning groove 11, thus realizing the positioning and installation of the air pump 10. During disassembly, the insertion block 8 is pulled by the pulling plate 9 to disengage the insertion block 8 from the positioning groove 11, so that the air pump 10 can be moved to the side for easy disassembly and maintenance later.
