Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a head and neck fixing device for CT examination. Background Art

[0002] A search of the patent document with publication number CN218572210U shows that the patient's head can be semi-enclosed and fixed by the occipital fixation pad, the first temporal fixation pad, and the second temporal fixation pad through the head fixation mechanism, the neck fixation mechanism, and the shoulder fixation mechanism. The neck and shoulders of the patient can be fixed by the inflatable neck pillow and the shoulder joint fixation pad. The elbow joint fixation pad connected to the shoulder joint fixation pad can support the patient's elbow joint.

[0003] This patent document uses a separate head fixation mechanism, a neck fixation mechanism and a shoulder fixation mechanism to fix the patient's head, neck and shoulders. This fixation method is more convenient for some patients who are clear-headed and do not move around. However, for some elderly patients who are unclear-minded and prone to moving around, since the patients themselves are not aware of their own behavior, family members are required to press and fix the patients before the entire fixation process can be carried out. Such separate fixation will greatly increase the fixation time, and will also make the patients feel irritable and cause larger movements, which will further affect the subsequent fixation operation and may also affect the patients' enthusiasm for subsequent cooperation with examinations.

[0028] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0029] The present invention will be further described below with reference to the accompanying drawings:

[0030] like Figures 1-8 As shown, a head and neck fixation device for CT examination includes a fixing plate 6, a neck airbag 5 is provided on the top of the fixing plate 6 for supporting the patient's neck, a head fixing mechanism 1 for limiting the patient's head and a shoulder pressing mechanism 2 for fixing the patient's shoulders.

[0031] The top fixing arm 14 is hinged with the top fixing arm 15, and the top fixing arm 15 is hinged with the top fixing arm 15. The head airbags 4 are connected to each other through the trachea, and the fastening seat 17 is flipped toward the outside of the fastening groove 16 by the fastening seat 17, so that the hook of the fastening seat 17 is disengaged from the bite portion 18, and the flipped fastening seat 17 is disengaged from the pressure on the tightening rope 13, and then the upper half of the tightening rope 13 can slide in the two side fixing arms 11 and the top fixing arm 14, and then the two side fixing arms 11 and the top fixing arm 14 lose the tension and fixation of the tightening rope 13, so that they can be flipped one by one to a position away from the patient's head, and then the patient's head can be taken out of the fixed position. Conversely, by tightening the tightening rope 13 downward, the two side fixing arms 11 and the top fixing arm 14 are gathered toward the patient's head, and the hooks on the two fastening seats 17 are engaged with the bite portions 18 in the two fastening grooves 16, so as to compress and fix the tightened tightening rope 13, thereby preventing the tightening rope 13 from sliding, and then completing the rapid fixation of the patient's head.

[0032] In this embodiment: the shoulder compression mechanism 2 includes a compression arm 21 located on both sides of the patient's neck, and the lower side of the compression arm 21 is hinged with a shoulder movable seat 22, and the shoulder movable seat 22 is slidably connected to the fixed plate 6. A fixing rope 23 is fixed on the side of the compression arm 21 close to the patient's shoulder, and a locking mechanism 3 is provided on the side of the fixing rope 23 away from the compression arm 21. The fixed plate 6 includes a top with three first sliding grooves distributed circumferentially with the patient's head as the center for the sliding of the two side movable seats 12 and the top movable seat 15. The fixed plate 6 is located at the patient's shoulder position and has two second sliding grooves for the movement of the shoulder movable seat 22. The fixing rope 23 is pulled to make the compression arm 21 flip toward the patient's shoulder with the shoulder movable seat 22 as the flipping center. The patient's shoulder is compressed and fixed by the compression arm 21 to prevent the patient from moving during neck examination.

[0033] When the locking mechanism 31 is unlocked, the locking plate 31 is unlocked and the locking groove 33 is opened. The locking plate 31 is slidably connected to the locking groove 33. A locking spring 32 is fixed to the end of the locking plate 31 away from the patient's shoulder. A rope groove 34 is opened in the locking groove 33 at the end away from the locking spring 32. The fixing plate 6 is provided with an L-shaped rope hole 35 at the locking groove 33. The rope hole 35 is connected to the rope groove 34. The end of the fixing rope 23 away from the pressing arm 21 passes through the rope hole 35. The locking spring 32 pushes the locking seat 31 to move in the locking groove 33, so that the locking seat 31 will press the fixing rope 23 passing through the locking groove 33 against the inside of the rope groove 34, thereby fixing the fixing rope 23 in the rope hole 35, and then the position of the pressing arm 21 after flipping can be locked.

[0034] When the locking spring 32 is pulled out of the locking groove 33, the locking seat 31 is released, and the locking spring 32 is used to push the locking seat 31 to move along the locking groove 33. Then, the locking seat 31 will press the fixing rope 23 passing through the locking groove 33 against the inside of the rope groove 34, thereby preventing the fixing rope 23 from moving inside the rope hole 35, and then indirectly locking the position of the pressing arm 21 after flipping.

[0035] The two side fixing arms 11 and the top fixing arm 14 are then turned over so that the three are gathered toward the patient's head. Then, the lower side of the tightening rope 13 is pulled and the two side fixing arms 11 and the top fixing arm 14 are gathered toward the patient's head again by tightening the rope 13, so that the upper ends of the two side fixing arms 11 and the top fixing arm 14 are attached to the two and top positions of the patient's head. Then, the fastening seat 17 is turned over toward the inner direction of the fastening groove 16, so that the hooks of the fastening seat 17 and the bite parts 18 of the fastening groove 16 are engaged with each other. The engaged fastening seat 17 will tighten the position of the tightening rope 13 passing through the fixing plate 6, thereby preventing the tightening rope 13 from sliding upward and losing the fixing effect on the patient's head. At this time, the initial fixation of the patient's head can be achieved, and during this process, the patient's head will not move significantly.

[0036] Then, compressed air is sent into the neck airbag 5 and the three head airbags 4, and the neck airbag 5 and the three head airbags 4 are continuously pressed to feel their softness and hardness. At the same time, the patient's comfort level is constantly asked, and then the patient's head is completely fixed;

[0037] When the entire CT examination is completed, the fastening seat 17 is flipped toward the outside of the fastening groove 16 to disengage the hook of the fastening seat 17 from the bite portion 18, and then the flipped fastening seat 17 is disengaged from the pressure on the tightening rope 13, and then the upper half of the tightening rope 13 can slide in the two side fixing arms 11 and the top fixing arm 14, and then the two side fixing arms 11 and the top fixing arm 14 lose the tension and fixation of the tightening rope 13, so that they can be flipped one by one to a position away from the patient's head, and then the patient's head can be taken out of the fixed position, and at the same time, the locking seat 31 is pushed to compress the locking spring 32, so that the locking seat 31 no longer pushes the fixing rope 23, and the pressing arm 21 can be flipped to release the patient's shoulder from fixation.

[0038] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements shall fall within the scope of the present invention as claimed.
