Figure 2 is a top view of the first embodiment of the utility model, Figure 3 The utility model Figure 2 AA line structural section view, Figure 4 It is a partial structural schematic diagram of the first embodiment of the utility model.

[0023] The utility model provides a CT examination head support, comprising a support seat 101, two fixing plates 102, a pillow 103 and a fixing component, wherein the fixing component comprises a rocker 104, a rotating rod 105, two groups of clamping members and a pressing member, each group of the clamping members comprises a moving block 106, a supporting rod 107, a sliding block 108, two dampers 109, a pressing plate 110 and a clamping plate 111, and the pressing member comprises a cross bar 112, a cylinder 113 and a supporting block 114. The above scheme solves the problem that a squeeze spring needs to be manually compressed, and the squeeze spring is released after the patient lies down to fix the patient's head through a splint, which is inconvenient for the doctor to operate and is easy to cause head injury to the patient due to a mistake, and there is a safety hazard, and the splint cannot be disassembled and cleaned, which is easy to cause the spread of bacteria on the head.

[0024] For this specific embodiment, the two fixing plates 102 are symmetrically arranged. The fixing plates 102 are fixedly connected to the support base 101 and are located above the support base 101. The pillow cushion 103 is fixedly connected to the support base 101 and is located above the support base 101. The fixing assembly includes a rocker 104, a rotating rod 105, two groups of clamping members and a pressing member. The rocker 104 is fixedly connected to one end of the rotating rod 105 and is located outside the support base 101. The other end of the rotating rod 105 is rotatably connected to the support base 101 and is located inside the support base 101. The surface of the rotating rod 105 has a double-thread. The two groups of clamping members are symmetrically arranged. The clamping members are threadedly connected to the rotating rod 105 and are located above the support base 101. The pressing member is fixedly connected to the fixing plate 102 and is located between the two fixing plates 102. The two fixing plates 102 support the pressing member. The patient's head lies flat on the surface of the pillow cushion 103. Rotate the rocker 104, and the rotating rod 105 drives the two groups of clamping members to clamp and fix the patient's head. The forehead of the patient is pressed and fixed by the pressing member. After the patient has used it, the clamping parts of the clamping members can be disassembled and disinfected. This method can effectively solve the problems that it is not convenient for doctors to operate, it is easy to accidentally hurt the patient's head, and it is easy to cause the spread of head bacteria.

[0025] Wherein, the moving block 106 is threadedly connected to the rotating rod 105 and is located inside the support base 101. The rotating rod 105 passes through the moving block 106. The support rod 107 is fixedly connected to the moving block 106 and is located above the moving block 106. The sliding block 108 is slidably connected to the support rod 107 and is located outside the support rod 107. The moving block 106 drives the support rod 107 to move. The sliding block 108 slides up and down on the surface of the support rod 107, so as to facilitate adjusting the position of the sliding block 108 according to the patient's head, improving the clamping stability and the comfort of the patient.

[0026] Secondly, one end of each of the two dampers 109 is fixedly connected to the sliding block 108 and is located outside the sliding block 108. The pressing plate 110 is fixedly connected to the other ends of the two dampers 109 and is located outside the dampers 109. The clamping plate 111 is detachably connected to the pressing plate 110 and is located outside the pressing plate 110. The pressing plate 110 pushes the clamping plate 111 to abut against the patient's head, and the damper 109 is compressed. While preventing excessive clamping, it makes the clamping plate 111 fit perfectly with the patient's head. Through the detachable connection between the clamping plate 111 and the pressing plate 110, the clamping plate 111 can be detached and disinfected and cleaned after the patient has used it, which is convenient for the next patient to use and effectively prevents the spread of head bacteria.

[0027] Meanwhile, the cross bar 112 is fixedly connected to the fixing plate 102 and is located between the two fixing plates 102. The air cylinder 113 is fixedly connected to the cross bar 112 and is located above the cross bar 112. And the output end of the air cylinder 113 penetrates through the cross bar 112. The supporting block 114 is fixedly connected to the output end of the air cylinder 113 and is located below the cross bar 112. The cross bar 112 fixes the air cylinder 113, and the air cylinder 113 pushes the supporting block 114 downward. By means of the supporting block 114 abutting against the patient's forehead position, the patient can be fixed more firmly.

[0028] In addition, the support base 101 has a moving groove 115 adapted to the support rod 107, the fixing plate 102 has a groove 116 adapted to the support rod 107, the support rod 107 has a sliding groove 117 adapted to the sliding block 108, and the pressing plate 110 has a clamping groove 118 adapted to the clamping plate 111. The support rod 107 slides in the moving groove 115 and is located in the groove 116 when not in operation. The sliding block 108 can easily adjust the clamping position of the clamping plate 111 according to the patient's head size through the sliding groove 117. Through the clamping groove 118, the clamping plate 111 can be easily removed from the pressing plate 110, so as to disinfect and clean the clamping plate 111 and prevent the infection of head bacteria.

[0029] Using a CT examination headrest according to this embodiment, by providing two fixing plates 102, a pillow cushion 103 and a fixing assembly, when in actual use, the patient lies flat with their head on the surface of the pillow cushion 103, the rocker 104 is rotated, the rotating rod 105 drives the moving block 106 to move, driving the support rod 107 to slide in the moving groove 115, the pressing plate 110 pushes the clamping plate 111 to hold the patient's head, the damper 109 is compressed, so that the clamping plate 111 fits perfectly with the patient's head, the sliding block 108 facilitates adjusting the clamping position of the clamping plate 111 according to the patient's head size through the sliding groove 117, the cylinder 113 pushes the supporting block 114 downward, the supporting block 114 holds the patient's forehead position, so that the patient's head is completely fixed in the device. After the patient has finished using, the clamping plate 111 is removed from the pressing plate 110 through the clamping groove 118, and the clamping plate 111 is disinfected and cleaned to prevent the spread of head bacteria, facilitating the use by the next patient. In this way, it can effectively prevent accidental injury to the patient during clamping, and prevent the spread of head bacteria through the detachable setting.

[0030] The second embodiment of this application is as follows:
