[0002] With the continuous development of society, people's medical level has also been significantly improved. During the process of clinical treatment, prone ventilation is an important treatment method to improve the oxygenation of ARDS patients.

[0003] In the prior art, the following problems exist in current clinical practice: 1. Facial pressure injury: In traditional prone position, the patient's head needs to be turned sideways, and the face, orbits, auricles, oral cavity and nasal cavity are under long-term pressure, which is likely to cause pressure injury; 2. Risk of tracheal intubation displacement: Turning the head sideways easily compresses and twists the tracheal intubation, resulting in a decrease in ventilation efficiency or accidental extubation; 3. Poor body position stability: Existing headrests lack multi-directional adjustment functions and are difficult to adapt to the body position requirements of patients with different body types. Summary of the Invention

[0004] The purpose of the present invention is to provide an adjustable hollow head fixing bracket dedicated to prone ventilation for the deficiencies of the prior art.

[0005] The specific technical solutions are as follows:

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments may be combined with each other.

[0024] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but it is not a limitation of the present invention.

[0025] An adjustable hollow head fixing bracket dedicated to prone ventilation provided in the present invention, referring to Figures 1 - 3 , includes: a base 1, a telescopic support device 2, a head support structure 3, and an artificial airway auxiliary fixing component 4; at least two telescopic support devices 2 are provided on the base 1, and the head support structure 3 is successively a metal support seat and an upper structure composed of a gel pad and memory foam from bottom to top, and the gel pad is located below the memory foam; the artificial airway auxiliary fixing component 4 is integrated at the top of the hollow area of the head support structure 3 and is connected to the metal support seat.

[0026] Specifically, during clinical use, medical staff can independently adjust the height of the left and right sides through the telescopic support device 2 according to the patient's body size and required body position. The artificial airway auxiliary fixing component 4 is a Y-shaped pipeline groove, which is connected to the metal support base and is used to fix the vertical position in the middle of the artificial airway. When performing prone ventilation for the patient, the artificial airway is placed in the Y-shaped pipeline groove. The structure of the Y-shaped pipeline groove can limit the horizontal and vertical displacement of the artificial airway and ensure the normal use of the artificial airway. The patient's head is placed on the head support structure 3. The gel pad and memory foam composite layer are used to reduce facial pressure injuries. Because the gel pad has a certain softness and elasticity, and the memory foam can adaptively deform according to the pressure shape of the head, the combination of the two can effectively disperse facial pressure and avoid pressure injuries caused by long-term pressure on the face, orbits, auricles, oral and nasal cavities during traditional prone positions. In clinical practice, after using this adjustable hollow head fixing bracket for prone ventilation, the incidence of facial pressure injuries in patients has been significantly reduced. Compared with traditional prone ventilation equipment, due to the effective buffering and pressure dispersion of the gel pad + memory foam 32 composite layer, the pressure injury conditions such as redness, breakage, and bleeding in the facial, orbital, auricular, oral and nasal cavity parts of the patient have been significantly reduced; through the fixation of the artificial airway auxiliary fixing component 4 and the reasonable lateral rotation of the head support structure 3, the situation of tracheal intubation being compressed and distorted almost no longer occurs, the ventilation efficiency is maintained at a stable level, and the incidence of accidental extubation is greatly reduced, improving the safety of the patient during the prone ventilation treatment process; the multi-directional adjustment function of the telescopic support device 2 enables patients of different body sizes to obtain a suitable prone ventilation body position. Whether the patient is thin or large in body size, they can adjust the telescopic support device 2 to achieve the best position and angle of the head support structure 3, improving the body position stability during the entire prone ventilation process and facilitating the smooth progress of the treatment. <C <C

[0027] Refer to <C Figure 2, each telescopic support device 2 includes a pneumatic rod 21, a lifting switch 22 and a rotating shaft 23. The pneumatic rod 21 is fixed to the base 1. The lifting switch 22 is used to adjust the lifting height of the pneumatic rod 21. One end of the rotating shaft 23 is fixedly connected to the head support structure 3, and the other end of the rotating shaft 23 is rotatably connected to the end of the pneumatic rod 21 away from the base 1. The telescopic support device 2 independently adjusts the height of the pneumatic rod 21 through the lifting switch 22 to adapt to different bed height requirements. Moreover, the rotating shaft 23 can enable the head support structure 3 to achieve lateral rotation fine-tuning. By adjusting the heights of the pneumatic rods 21 on the left and right sides respectively through the lifting switch 22, the head support structure 3 can reach different tilt angles. Before actual use, medical staff need to adjust the height of the pneumatic rod 21 of the telescopic support device 2 according to different bed heights. First, observe the height of the bed to determine the height range to be adjusted. Then, operate the lifting switch 22 to raise or lower the pneumatic rod 21. If the bed is relatively high, the medical staff presses the up button of the lifting switch 22 to increase the air pressure inside the pneumatic rod 21, thereby pushing the pneumatic rod 21 to rise until the head support structure 3 reaches a suitable height and can be adapted to the patient's body position, ensuring that the patient's head is in a suitable position during prone ventilation. If the bed is relatively low, then press the down button to lower the height of the pneumatic rod 21. After the patient lies prone on the head support structure 3, the medical staff may need to perform lateral rotation fine-tuning on the head support structure 3 according to the specific situation of the patient. By manually applying an external force to the head support structure 3, due to the connection relationship between the rotating shaft 23 and the pneumatic rod 21 and the head support structure 3, the rotating shaft 23 can rotate around its connection point with the pneumatic rod 21, thereby driving the head support structure 3 to achieve lateral rotation. For example, when it is necessary to turn the patient's head slightly to one side to meet special treatment needs or the comfort requirements of the patient, the medical staff can slowly push one side of the head support structure 3, and the rotating shaft 23 will rotate accordingly to achieve lateral rotation fine-tuning.

[0028] Referring to Figure 1 and Figure 2 , the artificial airway auxiliary fixing component 4 is a Y-shaped pipeline groove. The long end of the Y-shaped pipeline groove is communicated with the metal support seat and is used to fix the central vertical position of the artificial airway. The notch of the Y-shaped pipeline groove is adapted to the shape of the artificial airway, and a soft silica gel protective layer is pasted on the inner wall of the notch of the Y-shaped pipeline groove. When the artificial airway contacts the inner wall of the Y-shaped pipeline groove, the silica gel protective layer can buffer the frictional force between the artificial airway and the inner wall. The surface of the silica gel material is relatively smooth, and when contacting the artificial airway, it can reduce the possibility of scratching, thereby preventing the artificial airway from sliding and shifting and being scratched and damaged, ensuring the integrity and normal use function of the artificial airway.

[0029] The base 1 has a circular or square structure. A non-slip silica gel layer is provided at the bottom of the base 1. The non-slip silica gel layer at the bottom of the base 1 utilizes the relatively large friction characteristic of the silica gel material itself. When the device is placed on the bed surface or other flat surfaces, a large static friction will be generated at the contact between the non-slip silica gel layer and the flat surface. In addition, a plurality of sliding rollers can be evenly distributed at the bottom of the base 1, and a braking device is also provided at the position of the base 1 near the sliding rollers. The setting of the sliding rollers can facilitate the overall movement of the device to a predetermined position without the need to laboriously carry the entire device. When the base 1 moves to the predetermined position, by operating the braking device, the movement of the base 1 can be immediately stopped, avoiding the continuous sliding of the base due to inertia or other external forces (such as slight collisions or component forces of an inclined plane), thereby achieving precise positioning.

[0030] The outer layer of the upper structure of the head support structure 3 is wrapped with a waterproof and breathable fabric. The waterproof and breathable fabric wrapped around the outer layer of the upper structure of the head support structure 3 can prevent liquids (such as the patient's sweat, secretions, etc.) from penetrating into the inside of the head support structure 3, keeping the inside dry and clean. At the same time, the breathability of the fabric is based on the tiny pore structures on the fabric, and these pore structures can allow air to freely enter and exit, ensuring the air circulation around the patient's head and improving the patient's comfort.

[0031] Implementation principle:

[0032] Initial adjustment according to the patient's body type: Medical staff observe the patient's body type, including characteristics such as neck length and head size. Initially adjust the height of the telescopic support device 2 according to the height of the patient's bed, and then adjust the position of the base 1 according to the patient's neck length. If the patient has a larger body type, the telescopic support device 2 can be appropriately raised; if the patient has a smaller body type, the height of the telescopic support device 2 can be correspondingly lowered so that the head support structure 3 is roughly at a height that keeps the patient's head and back in a horizontal position.

[0033] Adjustment of the patient's lying position: Assist the patient to adopt the prone position, gently place the patient's head on the head support structure 3, and ensure that the patient's face is in full contact with the gel pad and memory foam composite layer. During the placement process, pay attention to adjusting the position of the patient's head so that it is at the center position of the head support structure 3 to ensure that the pressure is evenly distributed on the gel pad and memory foam, maximizing the role of reducing facial pressure injuries.

[0034] Placement of the artificial airway: Pick up the artificial airway and carefully place it in the Y-shaped pipeline groove, ensuring that the artificial airway is in the vertical center position of the Y-shaped pipeline groove. Check the fitting situation between the artificial airway and the Y-shaped pipeline groove, and confirm that the structure of the Y-shaped pipeline groove can effectively limit the horizontal and vertical displacement of the artificial airway, ensuring the normal use of the artificial airway.

[0035] Precise adjustment of the telescopic support device 2: Again, according to the patient's body type and comfort requirements, medical staff independently adjust the height of the left and right sides through the telescopic support device 2. During the adjustment process, closely observe the patient's body posture, especially the positions of the neck and shoulders, to ensure that the patient is in the most comfortable and physiologically compliant position during prone ventilation. For example, by finely adjusting the telescopic support device 2, keep the patient's neck in a natural extension state, avoiding excessive flexion or extension, and ensuring unobstructed airway. If it is found that there is a potential risk of compression or distortion between the tracheal intubation position of the patient and the head support structure 3, medical staff can make a lateral rotation adjustment to the head support structure 3. During the adjustment process, pay attention to controlling the lateral rotation angle of the head support structure 3 to ensure that it is within a reasonable range (such as 0-30°), so as to prevent the tracheal intubation from being compressed or distorted, and at the same time avoid uneven facial pressure distribution of the patient due to excessive rotation.

[0036] The above are only preferred embodiments of the present invention, and do not limit the implementation manners and protection scope of the present invention accordingly. For those skilled in the art, it should be able to realize that all equivalent replacements and obvious changes made by using the description and illustrated content of the present invention should be included in the protection scope of the present invention.
