[0002] Prone positioning ventilation refers to a method of ventilation performed by adopting a prone position. This ventilation method facilitates gas exchange in the lungs closer to the back, improving oxygenation; it can reduce pressure on the lungs from the mediastinum and heart, thus protecting the cardiovascular system; and it can also promote sputum expectoration. Some medical treatment protocols recommend standardized prone positioning therapy for certain critically ill patients.

[0003] As indicated by announcement number CN205198337U, a prone decompression pad is described. The device includes a main body, which is a rectangular thin block with multiple pads respectively placed on the head, face, chest, hips, and knees of a prone patient. The pads are detachably fixed to the surface of the main body. Straps are provided on both sides of the main body to bind the main body to the patient's body.

[0004] The aforementioned device has a fixed pad position during use and cannot be adjusted according to the patient's body shape, resulting in poor patient tolerance and unsuitability for long-term use, thus having limitations. Therefore, we propose an adjustable prone pressure relief device for critically ill patients to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable prone pressure relief device for critically ill patients, in order to solve the problem mentioned in the background art that the position of the pad is fixed during use, and the position of the pad cannot be adjusted according to the patient's body shape, resulting in poor patient tolerance and unsuitability for long-term use, thus having limitations.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable prone pressure relief device for critically ill patients, comprising a pressure-reducing bed body, a chest support pad installed on the left side of the top of the pressure-reducing bed body, a first groove and a second groove respectively provided at the front and rear ends of the top of the pressure-reducing bed body, a first threaded rod installed in the upper part of the first groove, a second threaded rod installed in the lower part of the second groove, a first slider installed on the left side inside the first groove and the second groove, a second slider installed on the right side inside the first groove and the second groove, a first connecting plate installed on the top of the two first sliders, an abdominal support pad installed on the top of the first connecting plate, a second connecting plate installed on the top of the two second sliders, a leg support pad installed on the top of the second connecting plate, and a U-shaped plate installed on the left side of the pressure-reducing bed body.

[0007] Preferably, a sliding rod is installed in the lower inner part of the first groove and the upper inner part of the second groove. The first slider and the second slider are slidably connected to the sliding rod. The first slider at the front end is threadedly connected to the first threaded rod, and the second slider at the rear end is threadedly connected to the second threaded rod. A first rocker arm is installed on the right side of the first threaded rod, and a second rocker arm is installed on the right side of the second threaded rod. A first through hole is provided in the lower inner part of the first slider at the rear end, and a second through hole is provided in the upper inner part of the second slider at the front end.

[0008] Preferably, the leg support pad is connected to the second connecting plate via an airbag, and a miniature air pump is installed at one end of the airbag.

[0009] Preferably, support legs are installed around the bottom of the decompression bed body, a support base plate is installed at the bottom of the support legs, and casters are installed around the bottom of the support base plate.

[0010] Preferably, a chin pad is installed on the right side of the top of the U-shaped plate, a third groove is provided at both ends of the top of the U-shaped plate, a third threaded rod is installed inside the third groove, a third slider is threaded to the outer wall of the third threaded rod, an upper pad is installed at the top between the two third sliders, and a knob is installed on the left side of the third threaded rod.

[0011] Preferably, a through groove is provided on the left side of the decompression bed body, and a roller is installed inside the through groove. The two ends of the roller are connected to the decompression bed body through bearings, and the roller is fixedly connected to the U-shaped plate.

[0012] Preferably, a hydraulic cylinder is installed in the middle of the left side of each of the two supporting legs on the left side. The other end of the hydraulic cylinder is connected to the bottom of the U-shaped plate, and the two ends of the hydraulic cylinder are rotatably connected to the supporting leg and the U-shaped plate respectively through hinge blocks.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model allows the first threaded rod to rotate by rotating the first rocker arm, thereby moving the first slider inside the first groove. Through the connecting action of the first connecting plate, the first slider inside the second groove can move along the sliding rod, thus achieving horizontal adjustment of the abdominal support pad. Similarly, rotating the second rocker arm allows the second threaded rod to rotate, thereby moving the second slider inside the second groove. Through the connecting action of the second connecting plate, the second slider inside the first groove can move along the sliding rod, thus achieving horizontal adjustment of the leg support pad. This solves the problem of existing prone decompression devices where the pad position is fixed during use, cannot be adjusted according to the patient's body shape, resulting in poor patient tolerance and unsuitability for long-term use, thus presenting limitations.

[0015] (2) By rotating the knob, the third threaded rod can be rotated, which allows the third slider to move along the third threaded rod inside the third groove, thereby adjusting the horizontal position of the forehead pad. This solves the problem that the existing prone decompression device cannot be adjusted arbitrarily according to the requirements of the patient's facial features, which is very inconvenient for the patient to use and can easily cause damage to the patient's face, thus failing to meet clinical needs.

[0016] (3) The U-shaped plate can be fixedly connected to the decompression bed body by the combined action of the roller and the bearing, and can rotate along one side of the decompression bed body. Under the combined action of the hydraulic cylinder and the hinge block, the U-shaped plate can be rotated upward or downward by the extension and shortening of the hydraulic cylinder, so as to realize the angle adjustment of the chin pad and the forehead pad, and avoid the patient's head being continuously pressured locally.

The casters 4 facilitate adjustment of the position of the decompression bed body 1 to meet the patient's needs and improve the device's practicality and usability. The support legs 2 and support base plate 3 work together to provide support for the decompression bed body 1 and also provide storage space for the patient's personal belongings. A chest support pad 5 is installed on the top left side of the decompression bed body 1. A first groove 6 and a second groove 7 are respectively provided at the front and rear ends of the top of the decompression bed body 1. A first threaded rod 8 is installed in the upper part of the first groove 6, and a second threaded rod 9 is installed in the lower part of the second groove 7. A first slider 11 is installed on the left side inside the first groove 6 and the second groove 7, and a second slider 12 is installed on the right side inside the first groove 6 and the second groove 7. A first connecting plate 17 is installed on the top of the two first sliders 11, and an abdominal support pad 18 is installed on the top of the first connecting plate 17. A second connecting plate 19 is installed on the top of the two second sliders 12, and a leg support pad 20 is installed on the top of the second connecting plate 19. Please refer to [link / reference]. Figure 4 and Figure 5A slide rod 10 is installed in the lower inner part of the first groove 6 and the upper inner part of the second groove 7. A first slider 11 and a second slider 12 are slidably connected to the slide rod 10. The front end of the first slider 11 is threadedly connected to the first threaded rod 8, and the rear end of the second slider 12 is threadedly connected to the second threaded rod 9. A first rocker arm 13 is installed on the right side of the first threaded rod 8, and a second rocker arm 14 is installed on the right side of the second threaded rod 9. A first through hole 15 is provided in the lower inner part of the rear end of the first slider 11, and a second through hole 16 is provided in the upper inner part of the front end of the second slider 12. Rotating the first rocker arm 13 can drive the first threaded rod 8 to rotate, thereby moving the first slider 11 inside the first groove 6. Through the connection of the first connecting plate 17, the first slider 11 inside the second groove 7 can move along the slide rod 10. The first through hole 15 prevents the second threaded rod 9 from rotating while the first slider 11 moves, thus enabling adjustment of the horizontal position of the abdominal support pad 18. Rotating the second rocker arm 14 causes the second threaded rod 9 to rotate, thereby moving the second slider 12 inside the second groove 7. Through the connection of the second connecting plate 19, the second slider 12 inside the first groove 6 can move along the slide rod 10. The second through hole 16 prevents the first threaded rod 8 from rotating while the second slider 12 moves, thus allowing for adjustment of the horizontal position of the leg support pad 20. A U-shaped plate 26 is installed on the left side of the decompression bed body 1. (See attached image.) Figure 1 and Figure 2 A chin pad 27 is installed on the right side of the top of the U-shaped plate 26. Third grooves 28 are provided at both ends of the top of the U-shaped plate 26. A third threaded rod 29 is installed inside the third groove 28. A third slider 30 is threadedly connected to the outer wall of the third threaded rod 29. A forehead pad 31 is installed at the top between the two third sliders 30. A knob 32 is installed on the left side of the third threaded rod 29. By rotating the knob 32, the third threaded rod 29 can be rotated, allowing the third slider 30 to move along the third threaded rod 29 inside the third groove 28, thereby adjusting the horizontal position of the forehead pad 31. After adjusting the horizontal positions of the forehead pad 31, abdominal support pad 18, and leg support pad 20 according to the patient's body shape, the patient is placed prone on the decompression bed body 1. The forehead pad 31, chin pad 27, chest support pad 5, abdominal support pad 18, and leg support pad 20 provide support and pressure relief for the patient's head, chest, abdomen, and legs respectively, improving patient comfort.

[0025] Please see Figure 1The leg support pad 20 is connected to the second connecting plate 19 via an airbag 21. A miniature air pump 22 is installed at one end of the airbag 21. The miniature air pump 22 can inflate or deflate the airbag 21, thereby controlling the expansion of the airbag 21 and adjusting the height of the leg support pad 20. This, in turn, adjusts the height of the patient's legs, allowing the patient's lumbar spine to maintain its natural physiological curvature and avoiding restrictive ventilation caused by chest compression.

[0026] Please see Figure 2 and Figure 3 A through groove 23 is provided on the left side of the decompression bed body 1. A roller 24 is installed inside the through groove 23. Both ends of the roller 24 are connected to the decompression bed body 1 through bearings 25. The roller 24 is fixedly connected to the U-shaped plate 26. Please refer to [link / reference]. Figure 3 Hydraulic cylinders 33 are installed on the middle left side of each of the two support legs 2 on the left side. The other end of the hydraulic cylinder 33 is connected to the bottom of the U-shaped plate 26. The two ends of the hydraulic cylinder 33 are rotatably connected to the support leg 2 and the U-shaped plate 26 respectively through hinge blocks 34. Under the combined action of the roller 24 and the bearing 25, the U-shaped plate 26 can be fixedly connected to the decompression bed body 1 and can rotate along one side of the decompression bed body 1. Under the combined action of the hydraulic cylinder 33 and the hinge block 34, the extension and retraction of the hydraulic cylinder 33 can drive the U-shaped plate 26 to rotate upward or downward, thereby realizing the angle adjustment of the chin pad 27 and the forehead pad 31. This can avoid continuous local pressure on the patient's head. Lowering the head height can provide space for endotracheal intubation, suctioning and other operations, while raising the head is conducive to the collection of oral secretions.
