[0020] 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, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0021] As shown in Figures 1-4, an adjustable prone head support device includes a base 1, on which a detachable U-shaped headrest is provided. First hinged bases 3 are provided on the left and right sides of the base 1. One end of the U-shaped headrest is hinged to the first hinged base 3, and the other end of the U-shaped headrest is connected to the base 1 through an angle adjustment component. An integrally formed folding plate 2 is provided on the left and right sides of the base 1. The folding plate 2 is provided with a plurality of anti-slip protrusions 10. A mirror 12 is provided on the upper side of the base 1.

[0022] Specifically, the outer edge of the first hinged base 3 is the bending part of the folding plate 2. When the folding plate 2 is in a bent state, it can abut against the base 1. To further fix the base 1, anti-slip protrusions 10 made of PVC foam are fixedly connected at the abutment position between the base 1 and the folding plate 2. This not only prevents the base 1 from shifting during patient use and causing injury, but also forms a double fixation with the base 1, effectively preventing important tubes such as endotracheal tubes, oxygen tubes, and nasoenteric tubes from being bent, pulled, or dislodged due to the displacement of the ventilation pillow. By setting an angle adjustment component, according to... The angle of the U-shaped headrest can be adjusted and its position limited according to the patient's usage habits or body shape; the mirror 12 is set between the two first hinge bases 3. For the patient's safety, the mirror 12 is a soft mirror; by setting the mirror 12, medical staff can easily observe the patient's face and throat area, and can clearly see the facial condition and tube interface through the reflection of the mirror without moving the patient's head, effectively reducing the risk of tube displacement caused by turning over. At the same time, the soft mirror material is soft, which can avoid the impact injury to the patient caused by hard lenses, and does not affect the patient's comfort in the prone position.

[0023] like Figure 1 and Figure 4 As shown, the U-shaped headrest includes a U-shaped support plate 8 and a U-shaped cushion 9, and the U-shaped cushion 9 is detachably connected to the U-shaped support plate 8 by Velcro 11.

[0024] The U-shaped cushion 9 consists of a sponge covered with a PU material layer. The internal sponge filling effectively disperses pressure on the face and neck, preventing skin pressure injuries and mucosal damage caused by prolonged prone positioning. It also prevents discomfort caused by prolonged facial compression. The sponge is covered with a PU material (artificial leather) for easy cleaning; it can be wiped clean after use. The disassembly and assembly process is simple and convenient, allowing for quick replacement and cleaning of the cushion while reducing the risk of cross-infection. It is suitable for use in various departments requiring prone ventilation, such as respiratory medicine, anesthesiology, and ICU. The U-shaped cushion 9 has a U-shaped structure similar to the commonly available U-shaped neck pillows. When the patient is in a prone position, it can suspend the patient's face and neck, ensuring ventilation and preventing the kinking, pulling, or dislodgement of important tubes such as endotracheal tubes or nasoenteric tubes during turning. The U-shaped cushion 9 and the U-shaped support plate 8 are respectively attached with the rounded and rough sides of Velcro 11, allowing for easy disassembly of the U-shaped cushion 9.

[0025] like Figure 2 As shown, one end of the U-shaped support plate 8 is hinged to the first hinge base 3, and two second hinge bases 5 are provided on the lower side of the other end of the U-shaped support plate 8.

[0026] Specifically, there are four first hinge bases 3, with two longitudinally arranged first hinge bases 3 on each side of the base 1 relative to the U-shaped support plate 8; there are two second hinge bases 5, which are symmetrically arranged at the other end of the U-shaped support plate 8, and the second hinge bases 5 and the first hinge bases 3 on the same side are on the same vertical horizontal plane.

[0027] like Figure 3 As shown, the angle adjustment assembly includes two controllable gas springs 4, two valves 6, and a U-shaped wrench 7. The valves 6 are mounted on the second hinged base 5. The bottom end of the controllable gas spring 4 is hinged to the first hinged base 3. The output end of the controllable gas spring 4 is connected to the valve 6. An arc-shaped U-shaped wrench 7 is connected in parallel between the two valves 6. The valve 6 includes a U-shaped plate 601 and a pressure rod 602 rotatably connected in the U-shaped plate 601. The U-shaped plate 601 is connected in the second hinged base 5 through a connecting rod 603. The pressure rod 602 abuts against the needle valve of the controllable gas spring 4. A stop plate 604 is provided at the end of the U-shaped plate 601. The pressure rod 602 can abut against the stop plate 604. The end of the pressure rod 602 is fixedly connected to the end of the U-shaped wrench 7.

[0028] Specifically, the controllable gas spring 4 is a self-locking type. This type of self-locking controllable gas spring can stop at any position in its stroke with the help of some release mechanisms, and has a large locking force after stopping. The U-shaped wrench 7 is used to drive the valve 6 to open or close to adjust the stroke of the controllable gas spring 4. When adjusting the tilt angle of the U-shaped headrest, the user holds the end of the U-shaped headrest with one hand and pulls the U-shaped wrench 7 upward. The U-shaped wrench 7 touches the valve 6 of the controllable gas spring 4 to open (that is, the pressure rod 602 presses the needle valve on the controllable gas spring 4, and the gas inside the controllable gas spring 4 can flow through the valve 6, the internal pressure chamber of the controllable gas spring 4 changes from a high-pressure chamber to a low-pressure chamber, and the controllable gas spring 4 enters a free extension and contraction state, losing its rigid locking ability), thereby unfolding the controllable gas spring 4 to adjust the tilt angle of the U-shaped headrest. This adjustment method can flexibly adapt to patients of different body types, such as adults and children, as well as different... The procedure meets the patient's cervical physiological curvature requirements and requires only one hand from the medical staff throughout, without the need for additional tools, significantly reducing the difficulty of nursing operations. When the U-shaped headrest is used horizontally, one hand is needed to firmly grasp the U-shaped headrest while simultaneously pulling the U-shaped lever 7 to overcome the downward force of the controllable gas spring 4, thereby causing the controllable gas spring 4 to contract and the U-shaped headrest to be in a horizontal state. The operation is simple and convenient. In other embodiments, the controllable gas spring 4 can also be a hydraulic push rod or an electric push rod, etc. The controllable gas spring 4, hydraulic push rod, or electric push rod are all existing technology products and will not be described in detail in this embodiment.

[0029] The working process of the adjustable prone head support device provided by this utility model is as follows:

[0030] The patient lies prone on the bed with their head placed on a U-shaped headrest. While adjusting the tilt angle of the U-shaped headrest, the patient holds the U-shaped headrest firmly with one hand and simultaneously activates or touches the U-shaped lever 7, causing the controllable gas spring 4 to rotate the U-shaped headrest to adjust its tilt angle. Once the tilt angle of the U-shaped headrest is adjusted, the patient releases the U-shaped lever 7, allowing the U-shaped headrest to remain in the tilted position.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
