[0002] Prone position ventilation (PPV) is widely used in the treatment of patients with acute lung injury and acute respiratory distress syndrome. There are various methods and auxiliary equipment for implementing PPV in clinical practice. They mainly include: (1) The traditional method of using foam dressings on the pressure area for prevention, raising the head and face with a horseshoe-shaped pillow, and stacking multiple soft pillows below the trunk. However, soft pillows have the following limitations: ① Soft pillows are soft and easily deformed by squeezing. They have poor stability and are not strong enough to support patients undergoing long-term PPV treatment. They are prone to displacement or collapse, and the abdomen cannot be suspended in the air, making it difficult to manage the patient's position. This not only affects the patient's respiratory movement and reduces the therapeutic effect of PPV, but may also increase the incidence of complications such as unplanned extubation and artificial airway kinking. ② The filling material of soft pillows is mostly cotton wool, which is easy to absorb water and is not conducive to drainage. It is easy to cause skin moisture and has poor decompression effect on the skin of the compressed area. The collapsed soft pillow may also increase the shear force and friction of the skin of the compressed area, thereby increasing the incidence of pressure injuries. (2) Assistive devices made of new materials such as silicone pads and gel pads have been recognized for their support effects, but they have poor air permeability, are bulky, are difficult to turn over, and are expensive. (3) Special equipment for turning over, such as Vollman prone assistive equipment and Rotoprone turning bed, are easy to operate, but the equipment is expensive and its clinical promotion is limited.
[0003] Moreover, the above methods all require the patient to be lifted up when placing the device, and turning the patient over is also time-consuming and labor-intensive.

[0037] Specifically, there are several limit blocks 201, and a first spring 204 is fixedly connected between one side of each limit block 201 and the upper support member 101. After the limit block 201 is squeezed, it will move toward the depth of the upper support member 101, squeezing the first spring 204 while moving, and then reset by the reaction force of the first spring 204. The other side of each limit block 201 is set to an arc surface, and rectangular grooves 205 are opened on both sides of the bottom end of the upper support member 101. The diameter of the rectangular groove 205 is consistent with that of the baffle 202. After rising, the baffle 202 will be located in the rectangular groove 205.
[0038] Further, the connecting member 203 includes a fixed block 203a disposed on the baffle 202, both sides of the top of each baffle 202 are fixedly connected with a fixed block 203a, a positioning block 203b disposed on the fixed block 203a, the positioning block 203b is slidably mounted on the fixed block 203a, a first rack 203c is disposed inside the fixed block 203a, the first rack 203c is slidably mounted inside the fixed block 203a, and a connecting frame 203d is disposed on the first rack 203c, and the two first racks 203c are fixedly mounted on the connecting frame 203d;
[0039] The positioning block 203b is engaged with the first rack 203c.
[0040] Furthermore, the anti-slip member 304 includes a fixing frame 304a arranged inside the cavity 206, there are several fixing frames 304a, two fixing frames 304a are fixedly installed on both sides of the cavity 206, a second rack 304b arranged on the fixing frame 304a, the second rack 304b is slidably installed on the fixing frame 304a, and a rubber pad 304c is arranged on the second rack 304b, and the rubber pad 304c is fixedly installed at the bottom of the second rack 304b.

The through groove enables the rubber pad 304c to descend and be on the same horizontal line as the bottom end of the lower support member 102, and the diameter of the through groove is consistent with that of the rubber pad 304c.
[0042] Operation process: When in use, the upper support member 101 and the lower support member 102 are assembled, and the connecting frames 203d on both sides are pulled upward, thereby driving the fixing block 203a and the baffle 202 at the bottom to rise. At this time, the connecting frame 203d will contact and squeeze the limit block 201. After the connecting frame 203d rises to the top, the limit block 201 is reset by the reaction force of the first spring 204 to block the connecting frame 203d, and the upper support member 101 and the lower support member 102 are connected together, and When the baffle 202 rises, it will also drive the teeth 303 to rise, causing the gear 302 to rotate, and then the second rack 304b will drive the rubber pad 304c to descend and be on the same horizontal line with the bottom end of the lower support member 102, thereby increasing the friction between it and the contact object and preventing the chest and abdomen pad 100 from shifting when the patient turns over. When the height of the chest and abdomen pad 100 does not match the patient's body shape, first pull the positioning block 203b so that it no longer engages with the first rack 203c, contact it, and then adjust the height through the adjustment component 400.
[0043] Example 2
[0044] Reference Figure 6 - Figure 7 , which is the second embodiment of the utility model. This embodiment is different from the first embodiment in that the positioning member 405 includes a rectangular block 405a arranged on the lower support member 102, and a clamping block 405b and a positioning plate 405c arranged on the rectangular block 405a. The clamping block 405b is rotatably mounted on the rectangular block 405a, a torsion spring (not marked in the figure) is sleeved on one side of the middle part of the clamping block 405b, and the positioning plate 405c is slidably mounted on the rectangular block 405a;
[0045] The bottom end of the positioning plate 405c contacts the top end of the block 405b, and a plurality of grooves 406 are provided on the outer wall of the turntable 403. One end of the block 405b contacts the groove 406. The block 405b and the groove 406 can prevent the turntable 403 from rotating, thereby preventing the patient from pressing the moving block 402 to reset due to his own weight after lying prone.
[0046] Specifically, the fixing member 504 includes a square groove 504a provided on the support block 503, the square groove 504a is provided on one side of the support block 503 close to the abutment plate 504b, and the abutment plate 504b is provided deep in the placement groove 501, the diameters of the square groove 504a and the abutment plate 504b are consistent, and the support block 503 is limited by moving the abutment plate 504b and engaging it with the square groove 504a, so that the support block 503 can stably support the upper support member 101;
[0047] There are several square grooves 504a which are equidistantly arranged on the support block 503. A second spring 505 is fixedly connected between the bottom end of the support block 503 and the bottom end of the inner wall of the square block 502. When the upper support member 101 rises, the support block 503 will no longer be squeezed. At this time, the reaction force of the second spring 505 causes the support block 503 to rise and contact the bottom end of the upper support member 101 again.
[0048] The rest of the structure is the same as that of Example 1.
[0049] Operation process: when adjusting the height of the chest and abdomen pad 100, the turntable 403 is rotated clockwise to rotate one of the positive and negative screw rods 401, and the two positive and negative screw rods 401 are rotated synchronously through the transmission of the belt, so that the moving block 402 on the surface moves to both sides and squeezes the inclined plate 404, and the upper support member 101 is squeezed and raised through the inclined surface of the inclined plate 404. The appropriate height is adjusted according to the patient's weight. After the upper support member 101 rises, there will be a gap between it and the lower support member 102. At this time, the support block 503 is no longer squeezed and rises through the reaction force of the second spring 505. When the lower support member 102 contacts the bottom end of the upper support member 101, the butt plate 504b is pushed and engaged with the corresponding square groove 504a, thereby fixing the support block 503, thereby increasing the supporting force of the lower support member 102 on the upper support member 101. The support block 503 can comprehensively increase the support for the upper support member 101, so that the patient can be stably supported when lying prone on the upper support member 101, thereby increasing the use scope and application scenarios of the chest and abdomen pad 100. Then the positioning block 203b is reset and engaged with the first rack 203c to prevent the patient from compressing the moving block 402 to reset due to his own weight after lying prone.
