[0019] To better understand the technical content of this utility model, specific embodiments are provided below, and the utility model will be further described in conjunction with the accompanying drawings.

[0020] See Figures 1-3 An inflatable pressure ulcer prevention sitting cushion includes a base 1. A first inflatable cushion 2 with a ring-shaped structure is disposed on the upper surface of the base 1, the ring structure better fitting and fully wrapping the patient's buttocks. A second inflatable cushion 3 is disposed on the inner side of the first inflatable cushion 2. The inner wall of the first inflatable cushion 2 is connected to two symmetrically distributed first extension pads 201, and the inner wall of the second inflatable cushion 3 is connected to two symmetrically distributed second extension pads 301. Depending on the patient's body shape and sitting posture, the first inflatable cushion 2, the second inflatable cushion 3, or a combination of both can be used. The first extension pads 201 and the second extension pads 301 can increase the contact area between the first inflatable cushion 2 and the second inflatable cushion 3 and the user's skin, thereby achieving better support and comfort. The first inflatable cushion 2 and the second inflatable cushion 3 are respectively connected to an inflation port 231 with a valve and an air outlet 232, facilitating inflation and air exchange to support the patient's buttocks. The outer wall of the first inflatable pad 2 has a through-hole groove 202, and the outer wall of the second inflatable pad 3 has a through-hole groove 302. The first groove 202 and the second groove 303 are used to match the contact surface of the buttocks, which can avoid squeezing the sacrum and coccyx and avoid pressure sores.

[0021] Specifically, the upper surfaces of the first air cushion 2 and the second air cushion 3 are connected by several semi-circular air cushion protrusions 233. When the first air cushion 2 and the second air cushion 3 are inflated, the air cushion protrusions 233 are also inflated to form supportive air cushion protrusions 233. With the flow of air, the air cushion protrusions 233 can massage the patient, avoid prolonged compression of the patient's buttocks, and prevent the patient from developing bedsores.

[0022] Specifically, the height of the first inflatable pad 2 is lower than that of the first extension pad 201, and the height of the second inflatable pad 3 is lower than that of the second extension pad 301, which facilitates wrapping the patient's buttocks and is suitable for different user body types.

[0023] Specifically, the outer walls of the first inflatable pad 2 and the second inflatable pad 3 are fitted with a cover 4. Two breathable pads 401, made of mesh fabric, are attached to the side of the cover 4 away from the base 1 via Velcro 402. By covering the outer walls of the first inflatable pad 2 and the second inflatable pad 3 with the cover 4, daily cleaning and maintenance can be performed simply by removing the cover 4 and the breathable pads 401, thus achieving an easy-to-clean effect. The mesh fabric enhances the breathability of the inflatable pads.

[0024] Specifically, the outer wall of the cover 4 has a through hole for the air inlet 231 and the air outlet 232 to pass through. The through hole facilitates the smooth passage of the air inlet 231 and the air outlet 232, thereby facilitating inflation and deflation.

[0025] Specifically, a sealing cap is threaded onto the outer wall of the inflation port 231. This seals the inflation port 231, protecting it and preventing damage.

[0026] The working principle and usage process of this utility model of an inflatable anti-pressure sore sitting cushion are as follows: Firstly, when using this device, the user can choose to use either the first inflatable cushion 2 or the second inflatable cushion 3 according to their body shape. When using the first inflatable cushion 2, air can be inflated into the first inflatable cushion 2 through the inflation port 231, filling it completely before entering the first extension pad 201. This allows the first inflatable cushion 2 and the first extension pad 201 to support the user, while the first slot 202 prevents pressure on the sacrum and coccyx, thus avoiding pressure sores. When using the second inflatable cushion 3, air can be inflated into the first extension pad 201. Air inlet 231 inflates the second air cushion 3, filling it completely and providing support to the user's buttocks. The second air cushion 3 and extension pad 301, along with the second perforation 302, prevent pressure on the sacrum and coccyx, thus avoiding pressure sores. The flexible use of either the first air cushion 2 or the second air cushion 3 adapts to different user body shapes and sitting postures, enhancing the overall flexibility of the structure. When used together, the different inflation volumes of the first and second air cushions match the patient's buttock structure, providing excellent support. The airflow within the first and second air cushions creates undulating surfaces on the seat cushion, increasing breathability and reducing local pressure and pressure sores, while also providing a massage effect on the buttocks.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
