[0033] As Figures 1 to 3 shown, an embodiment of the present utility model provides a body position fixing device, including a bearing plate 1, which is mainly used to provide a supporting force for other components. The bearing plate 1 is a square flat plate with arc chamfers at the corners to avoid sharp parts from stabbing patients and users, improving safety. The bearing plate 1 is made of plastic material, with light weight, convenient to carry, low cost, and can be widely used. A pair of clamping plates 2 are fixedly connected to the bearing plate 1, and the pair of clamping plates 2 are symmetrically distributed about the vertical central axis of the bearing plate 1 for clamping the patient's head. A positioning platform 3 is fixedly connected to the top of the bearing plate 1. The positioning platform 3 is located at the vertical central position of the bearing plate 1. A positioning groove 4 is formed on the top of the positioning platform 3. The positioning groove 4 is an irregular arc-shaped groove structure, and an opening is provided at a position close to the front side of the bearing plate 1, which is adapted to the human head and neck. The patient's head can be quickly positioned through the positioning groove 4 so that the head is located in the middle of the bearing plate 1, that is, in the middle of the two groups of clamping plates 2, so as to facilitate the two groups of clamping plates 2 to apply symmetric clamping forces to both sides of the head and keep the head balanced.

[0034] A group of buckle edges 5 are fixedly connected along the bottom edge of the supporting plate 1, and the number of the buckle edges 5 in a group is three. The buckle edges 5 are respectively fixedly connected to the two short sides of the supporting plate 1 and one of the long sides away from the neck. The cross-section of the buckle edges 5 is a J-shaped structure and is an arc-shaped elastic thin plate. When in use, the supporting plate 1 is moved to the head of the stretcher bed by translation. The buckle edges 5 at the bottom of the supporting plate 1 can be respectively clamped on the end of the stretcher bed and the frames on both sides, so as to facilitate the rapid fixing of the supporting plate 1 on the stretcher bed. Two groups of first lightweight grooves 6 are opened on the top of the supporting plate 1, and the two groups of first lightweight grooves 6 are respectively located on both sides of the positioning platform 3, which can reduce the weight of the device and facilitate carrying, while reducing the material consumption and reducing costs.

[0035] like Figure 1 and Figure 3 As shown, the splint 2 includes a buffer portion 7 fixedly connected to the side wall of the positioning table 3 with an end portion, and the buffer portion 7 is a V-shaped structure, which can be compressed to a certain extent. When in use, the buffer portion 7 has a supporting force on the head. In the process from the initial contact of the splint 2 to the complete pillow of the patient's head on the positioning table 3, the supporting force of the buffer portion 7 on the head can reduce the impact force of the positioning table 3 on the head, thereby improving the patient's comfort and safety. A clamping portion 8 is fixedly connected to the end of the buffer portion 7. The clamping portion 8 is an arc-shaped structure, and the buffer portion 7 and the clamping portion 8 are smoothly connected. The arc-shaped clamping portion 8 can fit the patient's head more closely, increase the force-bearing area of ​​the head, and avoid excessive local pressure causing indentations on the patient's head.

[0036] The end of the clamping part 8 is fixedly connected with a buckling part 9, which is located at the top sinking position of the clamping part 8. The buckling part 9 is a semicircular arc structure. The clamping part 8 is smoothly connected to the buckling part 9. After the head is located between the two sets of splints 2, the positioning platform 3 fits against the side of the head, and the buckling part 9 is pressed against the forehead position to limit the up and down movement of the head, and cooperates with the positioning platform 3 to restrict the patient's head in multiple directions, thereby improving the restraint force on the head. The end of the buckling part 9 is fixedly connected with a supporting part 10, and the supporting part 10 is an elongated S-shaped structure. The supporting part 10 is smoothly connected to the buckling part 9, and the other end of the supporting part 10 is fixedly connected to the supporting plate 1, and the supporting part 10 is used to support the positioning platform 3 and The buckling portion 9 is tilted toward the middle of the supporting plate 1 so that the two groups of splints 2 tend to move closer to each other. Under normal conditions, the spacing between the two groups of splints 2 should be smaller than the width of an average human head, so that when the head enters between the two groups of splints 2, the splints 2 generate a clamping force on the head. The splints 2 are made of plastic material, and the splints 2 are irregular arc-shaped spring plates as a whole. A second lightweight groove 11 is provided on the clamping portion 8 and the supporting portion 10. The second lightweight groove 11 is provided on the clamping portion 8, which can conveniently avoid the ears, so that the positioning platform 3 squeezes the ears when clamping the head, causing pain to the patient. At the same time, the second lightweight groove 11 can reduce the amount of material used, reduce the weight of the device, and facilitate carrying.

[0037] The working principle provided by the present utility model is as follows. When in use, first, the bearing plate 1 needs to be installed on the stretcher bed. First, the front edge at the bottom of the bearing plate 1 is lapped on the head end of the stretcher bed, and then the bearing plate 1 is pushed onto the stretcher bed by translation, so that the buckling edge 5 at the rear side of the bearing plate 1 is clamped with the frame at the top of the stretcher bed. Then, the operator needs to hold the buckling parts 9 on the two groups of splints 2 and forcefully separate the two adjacent buckling parts 9. At this time, the splints 2 are deformed. Then, support the patient's head, place the patient's head on the positioning table 3, and embed it into the positioning groove 4. Then release the hold on the buckling part 9, so that the two groups of splints 2 naturally close, and the positioning table 3 abuts against the side of the head and generates clamping force on the head.

[0038] The present utility model covers any alternatives, modifications, equivalent methods and solutions made on the essence and scope of the present utility model. In order to enable the public to have a thorough understanding of the present utility model, specific details are described in detail in the following preferred embodiments of the present utility model. However, those skilled in the art can fully understand the present utility model without the description of these details. In addition, in order to avoid unnecessary confusion to the essence of the present utility model, well-known methods, processes, procedures, components and circuits are not described in detail.

[0039] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
