The first support member 310 and the second support member 320 are both connected to the rotation adjustment assembly 200 and can rotate relative to the base 100 under the drive of the rotation adjustment assembly 200. The first support member 310 and the second support member 320 are separated from each other, and there is an avoidance space 500 between the first support member 310 and the second support member 320 for accommodating the mouth, nose and pipeline, and a pipeline fixer 400 is provided in the avoidance space 500.

[0032] Compared with the prior art, the prone position ventilation device in this embodiment has at least the following beneficial effects:

[0033] 1. The prone position ventilation device adopts a first support member 310 to support the forehead and face, and adopts a second support member 320 to support the chin, and the first support member 310 and the second support member 320 can rotate relative to the base 100 under the drive of the rotation adjustment component 200, so that the patient's body position can be changed in time, so that the patient can clear the artificial airway and oral and nasal secretions in an emergency, avoid blocking the airway and affecting the ventilation effect, and also avoid infection caused by aspiration of secretions;

[0034] 2. When the patient's body position is changed, the first support member 310 can still support the forehead and face, and the second support member 320 can still support the chin, thereby ensuring that the patient can get enough support, and the support area is large enough to reduce the pressure injury suffered by the patient;

[0035] 3. The prone position ventilation device is provided with an escape space 500 for accommodating the mouth, nose and pipelines between the first support member 310 and the second support member 320. While ensuring that the patient can get sufficient support, the patient's mouth, nose and pipelines such as endotracheal intubation can be accommodated in the escape space 500, and at the same time, it also provides operating space for medical staff to perform treatment;

[0036] 4. The prone position ventilation device is provided with a tube fixer 400 in the avoidance space 500, which can fix and protect tubes such as endotracheal tubes and deep venous catheters, avoid the tube from falling out when the patient changes position, and further ensure the safety of the patient.

[0037] Furthermore, if Figure 1 and Figure 2 As shown, the first support member 310 includes a forehead support member 311 and a face support member 312. The forehead support member 311 and the face support member 312 are integrally formed and arranged, and the overall structure is an arc-shaped curved surface structure with a depression in the middle and warped on both sides, which can better fit the forehead and face of the patient. Similarly, the second support member 320 is also arranged as an arc-shaped curved surface structure with a depression in the middle and warped on both sides to fit the chin of the patient. The structure of the first support member 310 and the second support member 320 designed in this way can be more in line with human body mechanics, not only can the support area of ​​the first support member 310, the second support member 320 and the patient's face be increased, but also when the angle of the first support member 310 and the second support member 320 is rotated to adjust, the patient's face can be stably supported to avoid displacement between the patient's face and the first support member 310 and the second support member 320 or even detachment from the first support member 310 and the second support member 320 and falling off. The inner sides of the first support member 310 and the second support member 320 may be covered with flexible pads such as sponges to further reduce the pressure injuries suffered by the patient.

[0038] Further, refer to Figures 1 to 5The support assembly 300 also includes an arc plate 330, which is connected to the rotation adjustment assembly 200 and can rotate relative to the base 100 under the drive of the rotation adjustment assembly 200. The first support member 310, the second support member 320 and the pipeline fixture 400 are all installed on the arc plate 330. When the arc plate 330 rotates relative to the base 100, it can drive the first support member 310, the second support member 320 and the pipeline fixture 400 thereon to rotate together, thereby adjusting the patient's position, and can maintain support for the patient's face during the process of adjusting the patient's position, and avoid the tube from falling off. Furthermore, the middle part of the arc plate 330 is concave downward, and the avoidance space 500 is located above the concave part of the arc plate 330, so that the avoidance space 500 is large enough to accommodate the patient's mouth and nose and the pipeline, and at the same time provide operating space for medical staff. Furthermore, the first support platform 340 and the second support platform 350 are mounted on the arc plate 330, and the bottoms of the first support member 310 and the second support member 320 are respectively connected to the tops of the first support platform 340 and the second support platform 350. In some embodiments, the first support member 310 and the second support member 320 are respectively detachably connected to the first support platform 340 and the second support platform 350, and the first support member 310 and the second support member 320 of different sizes can be manufactured so as to be replaced for patients with different face sizes.

[0039] Further, continue to refer to Figures 1 to 5 The rotation adjustment assembly 200 includes a lifting plate 210 and a worm 220. The lifting plate 210 is vertically movably connected to the base 100, and the worm 220 is rotatably connected to the lifting plate 210. The worm 220 is provided with worm gears 221, and the bottom surface of the arc plate 330 is provided with turbine gears 331. The worm gears 221 and the turbine gears 331 are meshed and connected. When the worm 220 rotates relative to the lifting plate 210, under the meshing action of the worm gears 221 and the turbine gears 331, the arc plate 330 will rotate relative to the base 100, thereby driving the first support member 310, the second support member 320 and the pipeline fixer 400 thereon to rotate together, thereby adjusting the patient's body position, and being able to maintain support for the patient's face during the process of adjusting the patient's body position, and preventing the tube from falling off. Furthermore, two first bearing seats 250 are provided on the lifting plate 210 , and bearings are installed in the first bearing seats 250 . Both ends of the worm 220 are inserted into the bearings in the first bearing seats 250 to support the worm 220 and facilitate the rotation of the worm 220 .

[0040] Furthermore, the rotation of the worm 220 can be realized manually, pneumatically or electrically. In some embodiments, the rotation adjustment assembly 200 also includes a rotation drive member 230 installed on the lifting plate 210. The worm 220 is fixedly connected to the output end of the rotation drive member 230. The rotation drive member 230 can be a structure such as a motor.

Further, referring to Figure 2 Two groups of supporting plates 240 are arranged opposite to each other on the lifting plate 210, and arc-shaped slide grooves 241 are opened on the supporting plates 240. Arc-shaped sliders 332 are provided on both sides of the bottom of the arc-shaped plate 330. The arc-shaped sliders 332 are slidably connected to the arc-shaped slide grooves 241, which can not only support the arc-shaped plate 330 on both sides, but also provide a guiding effect for the rotation of the arc-shaped plate 330, so that the rotation of the arc-shaped plate 330 is smoother.

[0041] Of course, in some other embodiments, a rotary drive motor can be directly installed on the side of the arc plate 330, and a rotating shaft perpendicular to its rotation plane can be fixedly installed on the arc plate 330, and the rotating shaft is fixedly installed on the output end of the rotary drive motor. When the rotary drive motor drives the rotating shaft to rotate, the arc plate 330 can also be driven to rotate. However, this structure is not as reliable in transmitting torque and smooth in movement as the structure shown in the drawings of the present invention.

[0042] Further, refer to Figure 6 The pipeline fixer 400 includes a universal tube 410 and a lock 420. The universal tube 410 has a notch 411. The lock 420 is installed at the notch 411 of the universal tube 410. Specifically, the entire universal corrugated tube can be cut along the axial direction to form the notch 411. The universal tube 410 can be rotated and adjusted in different directions to facilitate medical staff to perform medical operations such as bronchoscopy treatment on patients. When it is necessary to fix pipelines such as endotracheal intubation and deep venous catheters, the universal tube 410 is rotated to a suitable position, and the pipeline is placed into the universal tube 410 from the notch 411, and then the lock 420 is used to lock it. Specifically, the lock 420 squeezes the universal tube 410 along the notch 411, so that the notch 411 is deformed and reduced, and the diameter of the universal tube 410 becomes smaller, and the catheter can be locked and fixed with the lock 420. The lock buckle 420 can be a tape, Velcro, a clamp or a Thomas catheter fixer, etc., as long as it can fix the catheter.

[0043] Further, refer to Figure 1 and Figure 7 (In order to see the internal structure of the housing 110 more clearly, Figure 7In the figure, the two side panels and the top panel of the housing 110 have been hidden), the base 100 includes the housing 110 and the lifting and adjusting assembly 120 installed in the housing 110, and the rotating adjusting assembly 200 is installed at the output end of the lifting and adjusting assembly 120, and can drive the supporting assembly 300 thereon to move up and down under the drive of the lifting and adjusting assembly 120. Specifically, the lifting and adjusting assembly 120 includes a driving gear 121, a gear shaft 122, a lifting rack 123, a cross bar 124 and a lifting rod 125. There are two driving gears 121, and the two driving gears 121 are respectively fixedly connected to the two ends of the gear shaft 122, and the gear shaft 122 is rotatably connected to the housing 110. When the gear shaft 122 rotates relative to the housing 110, it can drive the driving gears 121 at both ends thereof to rotate synchronously together. The lifting rack 123 is vertically movable and connected to the housing 110. There are two lifting racks 123. The two lifting racks 123 are respectively meshed and connected to the two driving gears 121. When the driving gears 121 rotate, the lifting racks 123 meshed therewith will move up and down relative to the housing 110. There are two cross bars 124. The middle parts of the two cross bars 124 are respectively fixedly connected to the tops of the two lifting racks 123. Both ends of the cross bars 124 are fixedly connected to lifting rods 125. When the lifting rack 123 moves up and down relative to the housing 110, the four lifting rods 125 can be driven to move up and down together through the two cross bars 124. The top of the lifting rod 125 is fixedly connected to the rotation adjustment assembly 200, specifically, fixedly connected to the bottom of the lifting plate 210. When the lifting rod 125 moves up and down, it can drive the lifting plate 210 to move up and down together.
