[0038] Example 2
[0039] The operating principle of the utility model:
[0040] When medical staff perform nuclear medicine imaging examinations on patients, the patients need to lie on the examination bed, and the medical staff will perform intravenous injections of radioactive drugs on the patients after taking protective measures.
[0041] First, push the device to the side of the examination bed and close to the patient's arm position, then the medical staff operates the rotating handle 224 on the limit rod 223 to drive the limit rod 223 to rotate, the front end of the limit rod 223 rotates in the rotating shaft sleeve 222, and the rear end rotates on the threaded hole set on the other side of the limit plate 221, so that the scissor-type telescopic frame 22 moves up or down, thereby driving the moving plate 23 above the scissor-type telescopic frame 22 to move, so that the plane position of the moving plate 23 is adjusted to be consistent with the examination bed surface, so as to provide appropriate arm support for the patient. Rotate the arm support 24, and first move the pressing piece 26 to the tail end of the arm support 24. Let the patient's arm be placed on the arm support 24, and then fix the arm with the fixing belt 25 to ensure the stability of the arm during nuclear medicine imaging examination.
[0042] After the patient's arm is fixed, the medical staff can turn on the lighting device 4 to improve the clarity of the field of vision, and take out the relevant medical equipment from the tray 32 to perform intravenous injection of radioactive drugs on the patient. When the intravenous injection of radioactive drugs is completed, the medical staff uses a hemostatic pad to cover the eye of the needle to prevent bleeding. In order to ensure the effective fit of the hemostatic pad and prevent the drug from leaking out, the medical staff moves the elastic member 261 along the side of the arm support 24 to the vicinity of the eye of the needle, and then pulls the connecting rod 262 upward, aligns the pressing block 263 at the side end of the connecting rod 262 with the hemostatic pad, and then slowly lets go. The automatic retraction of the elastic member 261 can increase the pressure on the hemostatic pad, ensuring that the hemostatic pad is tightly covered at the injection needle eye. This tight coverage helps prevent the drug from leaking out of the eye of the needle, especially when the pressing operation is not precise enough.
[0043] Drug leakage can not only easily lead to unnecessary local radioactive concentration in patients, but also easily affect the final imaging results, thereby affecting the accuracy of diagnosis. Through this automatic pressurization method, the local retention of drugs can be more effectively controlled, potential problems caused by drug leakage can be reduced, and the imaging quality can be ensured not to be affected.
[0044] After the medical staff completes the injection operation, they rotate the rotating rod 316 manually or by using leg force to rotate the half gears 312 that mesh with each other, thereby driving the connecting block 313 to open the opening and closing plate 314, temporarily collecting the waste into the waste bin 31, and then release the rotating rod 316. Under the rebound of the spring 315 between the connecting blocks 313, the opening and closing plates 314 on both sides are automatically closed.
[0045] The injection process is completed when the needle hole pressure time on the patient's arm is over.
