[0023] 2) When the blood test equipment of this clinical department is in use, the gravity of the arm acts on the ring sleeve, and the ring sleeve moves downward, carrying the movable plate, sliding block and movable seat downward. The downward movement of the movable plate causes the fixed teeth to disengage from the fixed row of teeth, and the sliding block moves downward, carrying the fixed box and the clamping block downward. At this time, the clamping block cooperates with the fixed row of teeth, and the clamping block follows the movement of the sliding block and is squeezed and rotated by the fixed row of teeth. When the arm is extended to the blood collection position, it stops. At this time, when the clamping block is limited by the limit plate, the movable seat is fixed, and the inflatable pressure pulse ring is inflated to pressurize the adjacent muscle position, so that the veins burst, which facilitates the insertion of the blood collection needle and makes the blood collection process more convenient and quick.

[0024] 3) When the blood test equipment of this clinical department is in use, the movement of the mounting seat moves the limit ring, the guide rod and the fourth spring. When the limit ring first contacts the arm, as the mounting seat continues to move, the limit ring fixes the arm under the action of the fourth spring to prevent the arm from changing position due to pain, thereby ensuring stable insertion of the blood collection needle.

When the blood collection needle 18 completes the movement, the muscle position of the arm is not pressurized. At this time, under the action of blood pressure, the blood passes through the blood collection needle 18 and enters the blood collection tube 17 to complete the blood sampling. The scheme collects the position information of the vein through the image detector 14, and the threaded rod 22 rotates to move the arc-shaped slide 3 to the position of the vein where blood needs to be collected, so as to achieve To achieve the purpose of preliminary positioning, the connecting rod 27 slides inside the arc groove 26 and brings the arc slider 5 to slide on the surface of the two arc slide rails 4.

[0038] Example 3: Please refer to Figure 1 - Fig.10 , combined with the basis of Example 2, the difference is that the surface of the mounting seat 21 is slidably connected with a guide rod 47, the bottom surface of the guide rod 47 is fixedly connected with a limit ring 48, and a fourth spring 49 is elastically connected between the limit ring 48 and the mounting seat 21, one end of the fourth spring 49 is fixedly connected to the surface of the limit ring 48, and the other end of the fourth spring 49 is fixedly connected to the bottom surface of the mounting seat 21. The movement of the mounting seat 21 moves with the limit ring 48, the guide rod 47 and the fourth spring 49. When the limit ring 48 first contacts the arm, as the mounting seat 21 continues to move, the limit ring 48 fixes the arm under the action of the fourth spring 49 to prevent the arm from changing position due to the pain, thereby ensuring the stable insertion of the blood collection needle 18.

[0039] Usage steps of the present invention: When the clinical department blood test equipment is in use, at the moment when the blood collection needle 18 is inserted, the arm feels a tingling sensation, and the arm shakes due to the conditioned reflex. In order to ensure the normal insertion of the blood collection needle 18, during the movement of the mounting seat 21, the limit ring 48 first contacts the arm and fixes it. At this time, the movement of the limit ring 48 brings the guide rod 47 to move and compress the fourth spring 49. This scheme moves the limit ring 48, the guide rod 47 and the fourth spring 49 through the movement of the mounting seat 21. When the limit ring 48 first contacts the arm, as the mounting seat 21 continues to move, the limit ring 48 fixes the arm under the action of the fourth spring 49 to prevent the arm from changing position due to the pain, thereby ensuring the stable insertion of the blood collection needle 18.
