[0025] Example 1: Please refer to Figures 1 to 4 :

[0026] The utility model provides a CT examination head support, comprising: a scanning bed 1; a bottom block 2 is slidably mounted at the left end of the top of the scanning bed 1, and a threaded groove is provided in the middle of the upper end of the bottom block 2; two rows of limiting grooves 101 are provided at the left end of the scanning bed 1, and mutually parallel adjustment grooves 102 are provided at the left end of the top of the scanning bed 1, and a threaded column 3 is rotatably mounted at the threaded groove of the bottom block 2; a head support 4 is installed at the upper end of the threaded column 3, and an arc groove is provided in the middle of the upper end of the head support 4; the patient's head rests on the arc groove of the head support 4 for comfort, and mutually symmetrical guide rods 401 are fixedly installed at the bottom of the head support 4; the guide rods 401 are fixedly mounted ... The guide rod 401 is slidably installed in the guide hole 202. When the head support 4 slides up and down, the guide rod 401 is restricted by the guide hole 202, and the head support 4 can only slide up and down to prevent the head support 4 from being offset or tilted when sliding up and down. The arc groove of the head support 4 cannot stably support the patient's head, and arc-shaped limiting plates 402 are fixedly installed at both ends of the top of the head support 4; the patient's arms are respectively pressed against the inner concave surfaces of the two limiting plates 402, and are restricted by the two limiting plates 402, so that the patient's arms will not swing around and affect the scanning, and a rotating groove 403 is provided in the middle of the bottom of the head support 4.

[0027] Among them, the bottom of the bottom block 2 is fixedly installed with symmetrical adjustment plates 201, and the adjustment plates 201 are slidably installed in the adjustment grooves 102. When the bottom block 2 slides left and right, the adjustment plates 201 are restricted by the adjustment grooves 102, and the bottom block 2 can only slide left and right to prevent the bottom block 2 from deviating or tilting when sliding left and right, and the head support 4 will also be deviated and cannot be used. Guide holes 202 are respectively provided at both ends of the bottom block 2, and anti-slip grooves 203 are provided on the inner side walls of the threaded grooves of the bottom block 2. Ear plates 204 are respectively fixedly installed on the two side walls of the bottom block 2, and a penetrating circular hole is provided in the middle of the ear plates 204. Penetrating plastic spring rods 205 are respectively inserted in the circular holes of the two ear plates 204. The springs on the plastic spring rods 205 are made of lightweight materials. 5 is fixedly installed with a fixing plate 206 at the lower end, and the fixing plate 206 is attached to the side wall of the scanning bed 1. A limiting rod 207 is fixedly installed at the bottom of the fixing plate 206, and the lower end of the limiting rod 207 is inserted in the limiting groove 101. A stopper 208 is fixedly installed at the top of the plastic spring rod 205, and a pull ring is fixedly installed at the upper end of the stopper 208. Grasp the pull ring on the stopper 208, lift up the lower end of the limiting rod 207 and it will be pulled out of the limiting groove 101. At this time, grasp the bottom block 2 and slide left and right, and the position of the head support 4 will also slide with it. The position of the head support 4 is adjusted to facilitate the patient's head to rest on it. Release the pull ring on the stopper 208, and the lower end of the limiting rod 207 will be inserted in the corresponding limiting groove 101, so as to temporarily stabilize the head support 4.

[0028] Among them, a swivel ring 301 is fixedly installed at the upper end of the threaded column 3, and the outer ring of the swivel ring 301 is rotatably installed in the swivel groove 403, and a control disk 302 is rotatably installed on the threaded column 3, and a threaded hole is provided in the middle of the control disk 302. A short column is fixedly installed on the annular side wall of the outer end of the control disk 302. The short column on the control disk 302 is grasped for easy rotation. According to the different body shapes of each patient, the short column on the control disk 302 is grasped and rotated to move the threaded column 3 up and down. When the threaded column 3 moves upward, the position of the head support 4 will also move upward. Conversely, when the threaded column 3 moves downward, the position of the head support 4 will move downward, and the position of the head support 4 is adjusted to a suitable height, which is convenient for the patient to rest his head on the arc groove of the head support 4. The rotation of the control disk 302 can make the threaded column 3 move up and down, and an anti-slip disk 303 is fixedly installed at the bottom of the control disk 302, and the anti-slip disk 303 is rotatably installed in the anti-slip groove 203. When the control disk 302 rotates, it is restricted by the anti-slip groove 203 and will not deviate.

[0029] Embodiment 2, based on embodiment 1, as Figure 1 and Figure 4As shown, plastic spring rods 205 are respectively inserted through the circular holes of the two ear plates 204. The springs on the plastic spring rods 205 are made of lightweight materials. A fixing plate 206 is fixedly installed at the lower end of the plastic spring rods 205. The fixing plate 206, the plastic spring rods 205, the springs and other parts are all removed. The lower end of the limiting rod 207 is inserted into the corresponding limiting groove 101. The head support 4 can also be temporarily stabilized to prevent the springs on the plastic spring rods 205 from being damaged. At the same time, the problem of spring replacement is avoided, and the cost of using parts is saved.

[0030] The working principle of this embodiment is as follows: when in use, the patient's head rests on the arc-shaped groove of the head support 4, which is more comfortable. Grasp the pull ring on the stop head 208 and lift it upward, and the lower end of the limit rod 207 will be pulled out of the limit groove 101. At this time, grasp the bottom block 2 and slide it left and right, and the position of the head support 4 will also slide with it. The position of the head support 4 is adjusted to facilitate the patient's head to rest on it, release the pull ring on the stop head 208, and the lower end of the limit rod 207 will be inserted into the corresponding limit groove 101, temporarily stabilizing the head support 4, and then grasp the control panel 302. The short column is easy to rotate. According to the different body shapes of each patient, the short column on the control panel 302 is grasped to rotate and move the threaded column 3 up and down. When the threaded column 3 moves upward, the position of the head support 4 will also move upward. Conversely, when the threaded column 3 moves downward, the position of the head support 4 will move downward. The position of the head support 4 is adjusted to a suitable height to facilitate the patient to rest his head on the arc groove of the head support 4. The patient's arms are respectively pressed against the inner concave surfaces of the two limiting plates 402. Restricted by the two limiting plates 402, the patient's arms will not swing around and affect the scanning.
