[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. The present utility model will be further described below with reference to the embodiments.

[0018] Please see Figure 1 - Figure 3 In one embodiment of this application, the prone ventilation air cushion includes a support body and a support portion. The support portion is disposed on the support body and includes a face support air cushion 8, a shoulder support air cushion 2, a hip support air cushion 4, and a knee support air cushion 5 corresponding to the positions of the limbs. The face support air cushion 8, shoulder support air cushion 2, hip support air cushion 4, and knee support air cushion 5 are independently disposed and are respectively connected to an air pump through an inflation conduit 7. The shoulder support air cushion 2 and the knee support air cushion 5 are respectively provided with a phase change material 20. The face support air cushion 8 has an air vent 10 inside, and a collection box 9 for collecting secretions is provided inside the air vent 10. The side of the collection box 9 is slidably connected to the adjustment groove 11 on the inner wall of the air vent 10, so that the collection box 9 can be adjusted to be positioned directly opposite the mouth. The collection box 9 is connected to a secretion collection bag through a secretion collection tube 17, and a negative pressure pump 16 is installed on the secretion collection tube 17. The top of the collection box 9 is also connected to a water storage bag through a flushing water pipe 21, and a water pump 22 is installed on the flushing water pipe 21. In use, each part of the limb corresponds to the face support air cushion 8, shoulder support air cushion 2, hip support air cushion 4, and knee support air cushion 5, respectively, and the user lies prone on the support cushion. The air vent 10 is provided to facilitate ventilation, and the collection box 9 is positioned directly opposite the mouth to collect oral secretions (such as saliva). The negative pressure pump 16 and the water pump 22 can be activated periodically to collect and flush the secretions in the collection box 9.

[0019] The phase change material 20, designed to reduce pressure ulcers, can deform under temperature-triggered conditions. When the temperature at the contact point with the shoulder support air cushion 2 or knee support air cushion 5 rises due to prolonged prone positioning, causing the ambient temperature of the phase change material 20 to reach a preset value, the material changes from solid to liquid, softening to distribute pressure and prevent discomfort from prolonged prone positioning. After the patient is turned or moved, the phase change material 20 on the shoulder support air cushion 2 and knee support air cushion 5 returns to its original state as the ambient temperature decreases. It is worth noting that the melting point range and model parameters of the phase change material 20 can be adjusted according to clinical needs. This design solves the problem of uneven pressure distribution in existing mattress support areas, which can easily lead to pressure injuries in bony prominences such as the shoulders and knees due to prolonged pressure.

[0020] In this embodiment, the support pad includes a first mattress 3, a second mattress 1, and a third mattress 6. The first mattress 3 is fixedly mounted on the bed frame. The second mattress 1 and the third mattress 6 are located at both ends of the first mattress 3, and the distance between the second mattress 1 and the third mattress 6 and the first mattress 3 is adjusted by an adjustment mechanism to accommodate patients of different heights. The face support air cushion 8 and the shoulder support air cushion 2 are mounted on the second mattress 1, the hip support air cushion 4 is mounted on the first mattress 3, and the knee support air cushion 5 is mounted on the third mattress 6.

[0021] In one embodiment, the adjustment mechanism includes a guide rail 12, a motor 13, a threaded seat 14, and a lead screw 15. The guide rail 12 is fixedly connected to the first mattress 3. The threaded seat 14 is slidably installed inside the guide rail 12 and is threadedly connected to the lead screw 15. The threaded seat 14 is also fixedly connected to the second mattress 1 or the third mattress 6. The lead screw 15 is rotatably connected to the guide rail 12 and is also connected to the drive end of the motor 13. The motor 13 is mounted on the guide rail 12, thereby enabling the motor 13 to drive the lead screw 15 to rotate forward and backward to adjust the distance between the second mattress 1 or the third mattress 6 and the first mattress 3, thus making it suitable for patients of different heights and improving applicability.

[0022] In another embodiment, hydraulic rods can also be provided to adjust the distances between the second mattress 1 and the third mattress 6 and the first mattress 3, respectively.

[0023] To facilitate the collection of secretions, in this embodiment, the collection box 9 is connected to the secretion collection tube 17 via a guide tube 18. The secretion collection tube 17 is in communication with the collection bag.
