DETAILED DESCRIPTION

[0036] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0037] In the description of the present invention, it should be noted that the terms "front," "back," "upper," "lower," "both ends," "inner," and "outer" and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of the present invention and simplify the description. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limiting the present invention. Relational terms such as "first," "second," "third," and "fourth" are used solely to distinguish one entity from another or an operation, and do not necessarily require or imply any actual relationship or order between these entities.

[0038] Unless otherwise expressly specified or limited, the terms "installed," "connected," "connect," "fixed," and "disposed" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; they may refer to mechanical connections, direct connections, indirect connections through an intermediary, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0039] For easier understanding, see Figure 1-2 , the utility model is an adjustable neck auxiliary fixing device, comprising: a first fixing frame 11, a second fixing frame 12 and an adjusting rod;

[0040] The first fixing frame 11 and the second fixing frame 12 are respectively provided with a limiting assembly;

[0041] One end of the adjusting rod is movably connected to the limiting assembly on the first fixing frame 11 ; the other end of the adjusting rod is movably connected to the limiting assembly on the second fixing frame 12 .

[0042] It is understood that one end of the adjustment rod passes through the stop assembly on the first fixing frame, and the other end passes through the stop assembly on the second fixing frame, so that the first fixing frame, the second fixing frame, and the adjustment rod form a cylindrical structure that adapts to the person's neck. By adjusting the length of the adjustment rod between the first and second fixing frames, the height between the first and second fixing frames can be adjusted, thereby adjusting the height of the neck auxiliary fixation device. To adapt to the shape of the neck, the first and second fixing frames are circular or oval.

[0043] In this embodiment, the distance between the first fixing frame and the second fixing frame is adjusted by combining the adjustment rod with the limit assembly, thereby achieving height adjustment of the neck auxiliary fixation device to meet the needs of patients with different neck lengths.

[0044] In some embodiments, one end of the adjustment rod is movably connected to the limiting assembly on the first fixing frame 11; the other end of the adjustment rod is movably connected to the limiting assembly on the second fixing frame 12, specifically including:

[0045] The adjusting rod is the adjusting screw 21, and the limiting component is the threaded block 22;

[0046] One end of the adjusting screw rod 21 is rotatably connected to the threaded block 22 on the first fixing frame 11; the other end of the adjusting screw rod is rotatably connected to the threaded block 22 on the second fixing frame 12. The rotation makes adjustment and manufacturing easier and has good stability.

[0047] It is understood that the two threaded blocks are respectively mounted on the first fixing frame and the second fixing frame, the threads on the adjusting screw are adapted to the threads of the two threaded blocks, and the threads of the adjusting screw with different directions respectively engage with the threads on the inner walls of the two threaded blocks on the first fixing frame and the second fixing frame, thereby driving the two threaded blocks to move toward positions in different directions. Specifically, when the adjusting screw rotates clockwise or counterclockwise, the first fixing frame moves downward and the second fixing frame moves upward, thereby shortening the length of the adjusting screw between the first fixing frame and the second fixing frame, thereby shortening the height of the entire neck auxiliary fixing device; when the adjusting screw rotates in the opposite direction, the first fixing frame moves upward and the second fixing frame moves downward, thereby increasing the length of the adjusting screw between the first fixing frame and the second fixing frame, thereby lengthening the height of the entire neck auxiliary fixing device.

[0048] In a specific embodiment, a turning handle 23 is fixedly mounted on the end wall of the adjusting screw rod 21 , and the turning handle 23 is used to facilitate medical personnel to rotate the adjusting screw rod 21 .

[0049] See also Figure 4 In some embodiments, one end of the adjustment rod is movably connected to the limiting assembly on the first fixing frame 11; the other end of the adjustment rod is movably connected to the limiting assembly on the second fixing frame 12, specifically including:

[0050] The limiting assembly includes a limiting slider 42 and a positioning bolt 43;

[0051] One end of the adjusting rod is slidably connected to the limiting slider 42 on the first fixing frame 11; the other end of the adjusting rod is slidably connected to the limiting slider 42 on the second fixing frame 12;

[0052] The positioning bolt 43 passes through the limiting slider 42 and is contactably connected to the adjusting rod.

[0053] It is understandable that when the positioning bolt is loosened, the first fixing frame and the second fixing frame can slide on the adjusting rod respectively, and when the positioning bolt is tightened, the first fixing frame and the second fixing frame are fixed on the adjusting rod.

[0054] In a specific embodiment, the adjustment rod is a cylindrical limit screw 41, and the smooth surface makes it easier for the first fixing frame and the second fixing frame to slide and adjust. However, two such cylindrical rods are generally required to ensure that the first fixing frame and the second fixing frame can only slide up and down.

[0055] In another specific embodiment, the adjustment rod is a regular quadrangular prism, which can ensure that the first fixing frame and the second fixing frame will not shake left and right during the adjustment process.

[0056] In some embodiments, there are multiple adjustment rods, the number of limit assemblies is twice the number of adjustment rods, the multiple adjustment rods are evenly distributed, and every two limit assemblies correspond to one adjustment rod; by setting multiple adjustment rods and limit assemblies, the stability of the first fixing frame and the second fixing frame can be improved, and the shaking of the neck auxiliary fixing device can be avoided.

[0057] In some embodiments, the first fixing frame 11 is provided with an arc-shaped groove for fitting the mandible.

[0058] It can be understood that the arc-shaped groove is provided on the upper portion of the first fixing frame, and the opening of the arc-shaped groove faces upward, corresponding to the user's lower jaw.

[0059] Specifically, a rubber pad is installed in the arc groove to improve the comfort of the patient.

[0060] In order to make the arcuate groove more comfortable, in a specific embodiment, a cotton pad is provided on the arcuate groove to improve the comfort of the neck auxiliary fixation device.

[0061] In some embodiments, both the first fixing frame 11 and the second fixing frame 12 are provided with ventilation holes 13. The provision of ventilation holes can increase the breathability of the neck auxiliary fixation device, avoid the phenomenon of the neck skin being airtight causing the patient's skin to become moist and causing pressure sores, and improve protection for the patient.

[0062] In some embodiments, the number of the vent holes 13 is multiple;

[0063] A plurality of ventilation holes are evenly distributed on the first fixing frame 11 and the second fixing frame 12 to increase the air permeability of the fixing frame.

[0064] In some embodiments, the first fixing bracket 11 includes: a first U-shaped bracket and a second U-shaped bracket;

[0065] The open end of the first U-shaped bracket and the open end of the second U-shaped bracket are detachably connected;

[0066] The second fixing bracket 12 includes: a third U-shaped bracket and a fourth U-shaped bracket;

[0067] The open end of the third U-shaped bracket and the open end of the fourth U-shaped bracket are detachably connected.

[0068] See also Figure 3 In a specific embodiment, the two ends of the first fixing frame and the second fixing frame away from the hinge are respectively free ends (i.e., the open end of the first U-shaped bracket and the open end of the second U-shaped bracket), and the outer walls of the two free ends of the first fixing frame and the second fixing frame are respectively fixedly installed with fixing plates 31. A fixing component is provided between the two fixing plates 31, and the fixing component is used to lock the free ends of the first fixing frame and the second fixing frame, so that the first fixing frame and the second fixing frame form a closed ring structure.

[0069] Among them, the fixing assembly includes two through holes 34 opened on the fixing plate 31, and two fixing bolts 32 are movably installed on the two fixing plates located at adjacent positions. The fixing bolts 32 movably pass through the through holes 34, and a locking nut 33 is threadedly connected to the fixing bolts 32, and the locking nut 33 is used to lock and fix the two fixing plates 31; after the device is installed on the patient's neck and it is necessary to fix the openings of the first fixing frame 11 and the second fixing frame 12, the free ends of the first fixing frame 11 or the second fixing frame 12 can be attached together. At this time, the first fixing frame 11 and the second fixing frame 12 are both in a closed ring shape, and then the fixing bolts 32 are respectively passed through the two through holes 34 from the right fixing plate 31 to the left fixing plate 31, and the locking nut 33 is installed on the left side. After tightening the locking nut 33, the free end of the first fixing frame 11 or the second fixing frame 12 is closed. After installation, when the height of the device needs to be adjusted, an adjustment mechanism is provided between the first fixing frame 11 and the second fixing frame 12 to adapt it to patients with different neck lengths. When adjusting the distance between the first fixing frame 11 and the second fixing frame 12, hold the first fixing frame 11 or the second fixing frame 12 with one hand, and turn the handle 23 with the other hand. The threads in different directions on both sides of the outer wall of the handle 23 respectively engage with the threads on the inner walls of the two threaded blocks 22, thereby driving the two threaded blocks 22 to move to positions in different directions, thereby realizing the adjustment of the distance between the first fixing frame 11 and the second fixing frame 12.

[0070] In some embodiments, a shoulder fixing plate 14 is further included, and the shoulder fixing plate 14 is used to fix the adjustable neck auxiliary fixing device on the shoulder.

[0071] Specifically, there are two shoulder fixing plates, and the two shoulder fixing plates 14 are symmetrically arranged and respectively clamped on the two shoulders of the patient, so that the patient's lower jaw is placed in the arc groove. At this time, the distance between the first fixing frame 11 and the second fixing frame 12 can be adjusted so that the first fixing frame 11 and the second fixing frame 12 are respectively pressed against the patient's lower jaw and shoulders, thereby completing the auxiliary fixation of the patient's head and neck.

[0072] In some embodiments, cloth linings are provided on the inner sides of the first fixing frame and the second fixing frame. Soft cloth layers are provided on the inner sides of the first fixing frame and the second fixing frame to reduce damage to the patient's skin caused by the auxiliary neck fixing device.

[0073] The above is a detailed introduction to an adjustable neck auxiliary fixation device provided by the present invention. For those skilled in the art, according to the ideas of the embodiments of the present invention, there may be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
