DETAILED DESCRIPTION

[0021] The following is a detailed description of the embodiments of the present invention. The following embodiments are implemented on the premise of the technical solution of the present invention, and provide detailed implementation methods and specific operation processes, but the protection scope of the present invention is not limited to the following embodiments.

[0022] Example

[0023] Reference Figure 1 to Figure 4The technical solution of the utility model provides a head fixing device for scanning, including a base 1, and the base 1 is a U-shaped structure; a mounting groove 8 is provided on the top surface of one side of the base 1, and a rotating cylinder 9 is provided inside the mounting groove 8, and a clamping groove 11 is provided on both sides of the mounting groove 8, and the axis of the rotating cylinder 9 is movably installed with the clamping groove 11, and a film 10 is wrapped around the surface of the rotating cylinder 9.

[0024] During CT scanning, the staff can pull out the film 10 on the rotating drum 9 and lay it on the base 1. The patient lies on the U-shaped base 1 for testing, and the U-shaped base can fix and hold the patient's head. After a patient uses it, the staff will lift off the used film 10 and pull out a new film 10 from the rotating drum 9 for laying, ensuring the cleanliness of the surface of the base 1 to prevent cross infection. There is no need to disassemble the base 1 for cleaning, which is convenient for use.

[0025] A fixing groove 12 is provided on the top surface of the other side of the base 1 , and a pressing plate 13 is hingedly mounted on the top surface of the fixing groove 12 .

[0026] By setting the pressing plate 13, when the film is laid on the base 1, one end of the film is inserted into the fixing groove 12, and the medical staff turns the pressing plate 13 and presses it into the fixing groove 12 to fix one end of the film to prevent the film from falling off the base 1.

[0027] A support plate 14 is fixedly installed on one side of the inner part of the mounting groove 8, a cutting knife 15 is provided on the bottom surface of the support plate 14, a connecting hole 16 is opened on the top surface of the support plate 14, a connecting rod 17 is movably sleeved inside the connecting hole 16, one end of the connecting rod 17 is fixedly connected to the cutting knife 15, a pressing block 18 is fixedly installed on the other end of the connecting rod 17, and a spring 19 is provided on the outside of the connecting rod 17.

[0028] By setting the cutting knife 15, when the film is laid on the base 1, the medical staff presses the pressing block 18 to drive the cutting knife 15 to press down and cut one end of the film. At this time, the spring 19 is in a compressed state. After the medical staff releases the pressing block 18, the spring 19 rebounds and drives the cutting knife 15 to rise. By setting the cutting knife and the pressing block, the film can be cut quickly, and a new film can be replaced safely and conveniently.

[0029] The top surface of the base 1 is fixedly connected with a mounting frame 4, the top surface of the mounting frame 4 is provided with a threaded hole 6, the threaded hole 6 is internally threaded with a screw 7, the screw 7 is passed through the mounting frame 4, and one end of the screw 7 close to the base 1 is connected with an arc-shaped fixing plate 5 for fixing the head.

[0030] By providing the arc-shaped fixing plate 5, when the patient's head rests on the base 1, the medical staff turns the screw 7 to drive the arc-shaped fixing plate 5 to move downward to fix the patient's head, thereby preventing the patient's head from shaking during CT detection and affecting the detection result.

[0031] A soft pad 20 is fixedly bonded to the inner circular wall surface of the arc-shaped fixing plate 5 .

[0032] By providing the soft cushion 20, the comfort level of the arc-shaped fixing plate 5 when pressing against the patient's head is improved.

[0033] The arc-shaped fixing plate 5 and the cushion 20 are both provided with a plurality of ventilation holes 21 .

[0034] The ventilation holes 21 are provided to improve the air permeability of the arc-shaped fixing plate 5, thereby preventing the arc-shaped fixing plate 5 from pressing against the patient's head for a long time. When the patient sweats and covers his head, it is not breathable, which may easily cause discomfort symptoms such as redness, swelling, and itching of the patient's head skin.

[0035] Both sides of the bottom of the base 1 are provided with mounting plates 2 facing outwards, and mounting holes 3 are opened on the mounting plates 2 .

[0036] By setting the mounting plate 2 and the mounting hole 3, the head fixing device of the utility model can be fixed, which is convenient for the design of subsequent integrated fixing devices and avoids the patient from shaking left and right when being examined on the curved examination soft bed of large medical radiological examination equipment, thereby affecting the examination effect.

[0037] Working principle: When in use, the medical staff pulls out the film 10 on the rotating drum 9 and lays it on the base 1, and one end of the film is inserted into the fixing groove 12. The medical staff flips the pressing plate 13 and presses it into the fixing groove 12 to fix one end of the film to prevent the film from falling off the base 1. The medical staff twists the screw 7 to drive the arc-shaped fixing plate 5 to fix the patient's head. After a patient uses it, the medical staff presses the pressing block 18 to drive the cutting knife 15 to press down, cut the film, and lift off the used film 10; when another patient uses it, a new film 10 is pulled out from the rotating drum 9 for laying, ensuring that the surface of the base 1 is clean, and there is no need to disassemble the base 1 for cleaning, which is convenient for use.

[0038] The utility model can quickly cover the base 1 with a new film 10 by providing the film 10 and the cutting knife 15, thereby ensuring the cleanliness of the surface of the base 1 and preventing cross infection of patients. Moreover, the base 1 does not need to be disassembled for cleaning, which is convenient for use.

[0039] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
