[0022] Example

[0023] Reference Figure 1-4 An inflatable trapezoidal positioning pillow includes a hollow trapezoidal memory foam 1. Each side of the hollow trapezoidal memory foam 1 has a supine leg placement cavity 2, allowing the patient's legs to be placed in the corresponding supine leg placement cavity 2 when lying supine, thus separating and limiting the legs and ensuring stability between the legs and the hollow trapezoidal memory foam 1. The hollow trapezoidal memory foam 1 has integrated wing pieces 3 on its upper and lower surfaces to better support the patient's legs. The supine leg placement cavity 2 is located between the two corresponding wing pieces 3. The upper surface of the hollow trapezoidal memory foam 1 has a lateral leg placement cavity 4, allowing one leg of the patient to be placed in the lateral leg placement cavity 4 when lying on their side. The other leg is placed in one of the supine leg placement chambers 2, which allows the patient's legs to be separated and supports the leg in the lateral leg placement chamber 4, ensuring the stability of the leg on the hollow trapezoidal memory foam 1. One end of the lateral leg placement chamber 4 is connected to the supine leg placement chamber 2 to allow air circulation and avoid stuffiness. The hollow trapezoidal memory foam 1 has trapezoidal ventilation holes 5 running from the top to the bottom surface, which are connected to the lateral leg placement chamber 4 to allow air circulation and avoid stuffiness. The hollow trapezoidal memory foam 1 has round holes 6 running from one side to the other, which are perpendicularly connected to the trapezoidal ventilation holes 5 and the supine leg placement chamber 2 to allow air circulation and avoid stuffiness.

[0024] In this embodiment, a cationic fabric outer layer 7 with the same structural shape as the hollow trapezoidal memory foam 1 is fixedly sleeved on the outside of the hollow trapezoidal memory foam 1, so as to improve the breathability through the cationic fabric outer layer 7 and at the same time improve the comfort of the part in contact with the patient's leg.

[0025] In this embodiment, a closed airbag core 8 with the same structural shape as the hollow trapezoidal memory foam 1 is fixed inside the hollow trapezoidal memory foam 1. The airbag core 8 makes the whole body softer, improves the comfort during the leg support process, and makes it easy to deflate and store when not in use.

[0026] In this embodiment, an inflation / deflation structure is fixedly installed in the trapezoidal ventilation hole 5. Since the inflation / deflation structure is set in the trapezoidal ventilation hole 5, it can not only prevent accidental contact during use, but also make the whole thing neater and more beautiful. The inflation / deflation structure is located outside the cationic fabric outer layer 7, and the inflation / deflation structure passes through and is fixedly connected between the cationic fabric outer layer 7, the hollow trapezoidal memory foam 1, and the airbag core 8.

[0027] In this embodiment, the inflation / deflation structure includes an inflation bladder 9 and an exhaust valve 10. The inflation bladder 9 and the exhaust valve 10 are fixedly installed on the outside of the cationic fabric outer layer 7 in the trapezoidal ventilation holes 5. One end of the inflation bladder 9 and the exhaust valve 10 pass through the cationic fabric outer layer 7 and the hollow trapezoidal memory foam 1 and are fixedly connected to the air bladder core 8, so that when in use, air can be inflated into the air bladder core 8 through the inflation bladder 9 to make the whole structure unfold. At the same time, when not in use, the gas in the air bladder core 8 can be released by opening the exhaust valve 10 to make the whole structure shrink for storage.

[0028] In this embodiment, the hollow trapezoidal memory foam 1 is made of slow rebound memory foam. Through the setting of slow rebound memory foam, it can dissipate heat and be breathable, fit the body and relieve pressure, and be soft and comfortable.

[0029] Specifically, before use, the airbag core 8 is inflated through the inflatable balloon 9.

[0030] When used in a supine position, place this inflatable trapezoidal positioning pillow between the patient's legs, with the smaller end facing the side of the patient's head. Then, place the patient's legs in the corresponding supine leg placement cavity 2. At the same time, a detachable restraint strap can be used to fix the patient's legs to the inflatable trapezoidal positioning pillow to ensure the stability between the patient's legs and the inflatable trapezoidal positioning pillow and prevent the patient's legs from detaching from the inflatable trapezoidal positioning pillow.

[0031] like Figure 1When using the first lateral decubitus position, place this inflatable trapezoidal positioning pillow horizontally on the bed surface, with the lateral decubitus leg placement cavity 4 on top. Then adjust the patient's position so that one of the patient's legs is placed in the lateral decubitus leg placement cavity 4 and the other leg is placed in one of the corresponding supine leg placement cavities 2. At this time, the patient's legs will be separated, and the leg in the lateral decubitus leg placement cavity 4 will be supported. It can also be used with a detachable restraint strap.

[0032] like Figure 2 When using the second lateral decubitus position, first adjust the patient's position, then place the inflatable trapezoidal positioning pillow horizontally between the patient's legs, with the lateral decubitus leg placement cavity 4 facing down and the bottom surface facing up. Place one of the patient's legs in the lateral decubitus leg placement cavity 4 and the other leg on the bottom surface of the inflatable trapezoidal positioning pillow. At this time, the patient's legs will be separated, and the legs on the bottom surface of the inflatable trapezoidal positioning pillow will be supported. It can also be used with detachable restraint straps.

[0033] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
