[0020] The fixing mechanism 4 includes a base 401, a movable groove 402, an adjusting block 403, a second spring 404, a limiting column 405, a steel cable 406, a pull ring 407, a handle 408, a slot 409, a support rod 410, a neck support 411 and a protective sheet 412. One side of the surface of the pillow 2 is fixedly connected to the base 401, one side of the surface of the base 401 is provided with a movable groove 402, one side of the surface of the base 401 is embedded with the adjusting block 403, the inside of the movable groove 402 is provided with a second spring 404, one end of the second spring 404 is fixedly connected to the limiting column 405, and the limiting One end of the column 405 is fixedly connected to a steel cable 406, and the other end of the steel cable 406 is fixedly connected to a pull ring 407. One side of the surface of the adjusting block 403 is fixedly connected to a handle 408, and the other side of the surface of the adjusting block 403 is provided with a slot 409. The upper side of the adjusting block 403 is fixedly connected to a support rod 410, and the other end of the support rod 410 is fixedly connected to a neck support 411. One side of the surface of the neck support 411 is bonded to a protective sheet 412. 407, handle 408, slot 409, support rod 410, neck support 411 and protective sheet 412 are arranged. First, pull the pull ring 407. At this time, the pull ring 407 drives the limiting column 405 to move into the inside of the movable groove 402 through the steel cable 406. At the same time, the second spring 404 is compressed and deformed. When the limiting column 405 is completely embedded in the inside of the movable groove 402, pull the handle 408. At this time, the handle 408 drives the adjustment block 403 to slide on one side of the surface of the base 401. Then let the patient lie on the bed 1 with his neck resting on the pillow 2, and then push the handle 408 to The adjusting block 403 is moved, and the adjusting block 403 drives the neck support 411 to move through the support rod 410, so that the neck support 411 supports the patient's neck, and then the force applied to the pull ring 407 is released. At this time, the second spring 404 rebounds and drives the limiting column 405 to return to its original position. At this time, one end of the limiting column 405 is embedded in the inside of the card slot 409, so that the limiting column 405 fixes the adjusting block 403 at a suitable position inside the base 401. At this time, the two sets of neck supports 411 fix the patient's head, and at the same time, the protective sheet 412 made of silicone material can protect the patient's neck.

[0021] Furthermore, one end of the second spring 404 is fixedly connected to the base 401 inside the movable groove 402, and one end of the limiting column 405 is embedded in the slot 409. Through the setting of the second spring 404, when in use, the rebound of the second spring 404 can drive the limiting column 405 to return to its original position, so that the limiting column 405 plays a limiting role on the adjustment block 403.

[0022] Furthermore, four groups of card slots 409 are provided, and the card slots 409 are distributed at equal intervals. The protective sheet 412 is made of silicone material. Through the setting of the card slots 409, since the four groups of card slots 409 are distributed at equal intervals, when one end of the limiting column 405 is embedded in the card slots 409 at different positions, the adjustment block 403 can be fixed at different positions inside the base 401, so that the position of the neck support 411 can be adjusted.

[0023] Furthermore, the mounting mechanism 3 includes a mounting hole 301, a limiting rod 302, a limiting groove 303, a first spring 304, a limiting piece 305 and a stopper 306. A mounting hole 301 is provided on one side of the surface of the bed body 1, and a limiting rod 302 is connected to one side of the surface of the pillow 2. A limiting groove 303 is provided inside the limiting rod 302. A first spring 304 is provided inside the limiting groove 303. One end of the first spring 304 is fixedly connected to the limiting piece 305. The other side of the surface of the limiting piece 305 is fixedly connected to the stopper 306. 04. The setting of the limiting plate 305 and the stopper 306. When the pillow 2 needs to be installed on the bed body 1, first press the stopper 306. At this time, the stopper 306 squeezes the first spring 304 to compress and deform the first spring 304. When the stopper 306 is completely embedded in the limiting groove 303, the limiting rod 302 is inserted into the mounting hole 301, and then the force applied to the stopper 306 is released. At this time, the first spring 304 rebounds and drives the stopper 306 to return to its original position. At this time, the stopper 306 fixes the limiting rod 302 inside the mounting hole 301, thereby installing the pillow 2 on the bed body 1.

[0024] Furthermore, two groups of mounting holes 301 are provided, and two groups of limiting rods 302 are provided. The cross-sectional size of the limiting rods 302 is consistent with the size of the mounting holes 301. One end of the first spring 304 is fixedly connected to the limiting rod 302 inside the limiting groove 303. Through the setting of the first spring 304, when the force applied to the stop block 306 is released, the rebound of the first spring 304 can drive the stop block 306 to return to its original position.

[0025] Working principle: When installing the pillow 2 on the bed body 1, first press the stopper 306. At this time, the stopper 306 squeezes the first spring 304 to compress and deform the first spring 304. When the stopper 306 is fully embedded in the limiting groove 303, the limiting rod 302 is inserted into the mounting hole 301, and then the force applied to the stopper 306 is released. At this time, the first spring 304 rebounds and drives the stopper 306 to return to its original position. At this time, the stopper 306 fixes the limiting rod 302 inside the mounting hole 301, thereby installing the pillow 2 on the bed body 1. When cerebral angiography is required for the patient, pull the pull ring 407. At this time, the pull ring 407 drives the limiting column 405 to move toward the inside of the movable groove 402 through the steel cable 406. At the same time, the second spring 404 is compressed and deformed. When the limiting column 405 is fully embedded When inside the movable groove 402, pull the handle 408, at this time, the handle 408 drives the adjusting block 403 to slide on one side of the surface of the base 401, and then let the patient lie on the bed 1 with his neck on the pillow 2, and then push the adjusting block 403 through the handle 408. At this time, the adjusting block 403 drives the neck support 411 to move through the support rod 410, so that the neck support 411 supports the patient's neck, and then releases the force applied to the pull ring 407. At this time, the second spring 404 rebounds and drives the limiting column 405 to return to its original position. At this time, one end of the limiting column 405 is embedded in the inside of the card slot 409, so that the limiting column 405 fixes the adjusting block 403 at a suitable position inside the base 401. At this time, the two sets of neck supports 411 fix the patient's head, and at the same time, the protective sheet 412 made of silicone material can protect the patient's neck.
