[0017] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.
[0018] See also Figure 1-3This embodiment provides a technical solution: an auxiliary fixation device for radiation, including a bed 1 and a positioning film 6, a fixing seat 8 is fixed to the side of the positioning film 6, a lifting mechanism 7 is installed at the bottom of the bed 1, a connecting belt 3 is connected to the lifting mechanism 7, and a connecting seat 9 is fixed to the end of the connecting belt 3. The connecting seat 9 is detachably connected to the fixing seat 8 through a fixing mechanism 4. A through hole 5 is opened on the bed 1 for the connecting belt 3 to pass through. The patient lies on the bed 1 with his head resting on the headrest of the bed 1, and then the positioning film 6 is covered on the patient's face.
[0019] The lifting mechanism 7 includes a cylinder 71 and a lifting seat 72. The cylinder 71 is installed at the bottom of the bed body 1. The lifting seat 72 is fixed to the telescopic end of the cylinder 71. One end of the connecting belt 3 is fixedly connected to the lifting seat 72. The telescopic end of the cylinder 71 drives the lifting seat 72 to move downward. The lifting seat 72 pulls down the connecting seat 9 through the connecting belt 3, so that the positioning film 6 covers and fixes the patient's head position. It is easy to fix, avoiding the trouble of tightening and fixing multiple fixed positions of the positioning film one by one, saving time and effort, and at the same time, avoiding secondary damage to the patient caused by the positioning film during the oblique pulling process.
[0020] It also includes a guide roller 2, which is rotatably installed on the inner side of the through hole 5. The connecting belt 3 is pressed against the surface of the guide roller 2 during the tensioning process. The connecting belt 3 rubs against the guide roller 2 during the downward movement to cause it to rotate, thereby avoiding wear caused by contact friction between the connecting belt 3 and the bed body 1.
[0021] The fixing mechanism 4 includes a spring 41, a slider 43 and a guide rod 44. The end of the guide rod 44 is fixedly connected to the connecting seat 9. The slider 43 is slidably connected to the guide rod 44. The spring 41 is sleeved on the guide rod 44. The spring 41 is arranged between the slider 43 and the connecting seat 9. The fixing mechanism 4 also includes a paddle 42. The paddle 42 is fixed to the top of the slider 43. The fixing mechanism 4 also includes a jack 45 and a plug 46. The plug 46 is fixed to the bottom of the slider 43. The jack 45 is opened on the fixing seat 8. The plug 46 is plugged with the jack 45. The medical staff can dial the The paddle 42 drives the slider 43 to slide along the guide rod 44, and the slider 43 squeezes the spring 41. At this time, the two plugs 46 located on the same connecting seat 9 are in a state of being away from each other. Then, the plug 46 is positioned toward the socket 45 and the paddle 42 is released. At this time, the spring 41 recovers its deformation, and the deformation force of the spring 41 reacts on the slider 43, thereby returning the plug 46 to its original position. At this time, the plug 46 can be plugged into the socket 45, thereby fixing the fixing seat 8 and the connecting seat 9. It is easy to fix and disassemble, and is convenient to use.
[0022] The working principle of the auxiliary fixation device for radiation provided by the present invention is as follows: the patient lies on the bed 1 with his head resting on the headrest of the bed 1, and then the positioning film 6 is covered on the patient's face. The medical staff uses his fingers to move the paddle 42, and the paddle 42 drives the slider 43 to slide along the guide rod 44. The slider 43 squeezes the spring 41. At this time, the two plugs 46 located on the same connecting seat 9 are in a state of moving away from each other. Then, the plug 46 is aligned with the position of the socket 45 and the paddle 42 is released. At this time, the spring 41 recovers its deformation, and the deformation force of the spring 41 reacts on the slider 43, so that the plug 46 returns to its original position. At this time, the plug 46 can be plugged into the socket 45, thereby fixing the fixing seat 8 and the connecting seat 9. Then, the telescopic end of the cylinder 71 drives the lifting seat 72 to move downward, and the lifting seat 72 pulls down the connecting seat 9 through the connecting belt 3, so that the positioning film 6 covers and fixes the patient's head position.
