Working principle: when in use, a patient firstly penetrates the limbs after the puncture into the positioning opening 2, the puncture hole is positioned below the hemostatic cotton 8, the rest of the limbs are put on the bracket 35, then the driving motor 13 is started, the threaded screw rod 11 can be rotated, the first nut 12 drives the slider 3, the connecting rod 4 and the hemostatic cotton 8 to move downwards until the hemostatic cotton 8 is pressed on the puncture hole on the limbs of the patient, the radial artery puncture hole of the patient can be pressed for hemostasis by electric, in addition, in the sliding process of the slider 3, the C-shaped frame 20 can drive the roller 22 to roll in the limit groove 19, the movement direction of the slider 3 can be limited, the problem of deflection of the slider 3 in movement is avoided, the friction force between the slider and the inner wall of the cavity 17 can be reduced by changing the sliding friction of the limit structure into rolling friction, the friction loss can be relieved, in addition, the electric energy for using the driving motor 13 can be saved, when the hemostatic cotton 8 presses the puncture hole of a patient, the hemostatic cotton 8 drives the sliding block 10 to move upwards in the sliding rail 9 along the direction of the guide rod 14, the connecting spring 15 is compressed, the hemostatic cotton 8 is further against the pressure detector 16, when the pressure of the hemostatic cotton 8 to the pressure detector 16 reaches the rated pressure set in the pressure detector 16, the pressure detector 16 can send an electric signal to the driving motor 13 and automatically control the driving motor 13 to be closed, at the moment, the hemostatic cotton 8 can effectively press the puncture hole without damaging the limb of the patient, the effect of controlling the force of pressing the puncture hole is realized, when the timer 23 reaches the rated time interval set in the interior, the electric signal can be sent to the controller 24, and then the controller 24 sends the electric signal to the driving motor 13 and activates the same, the driving shaft of the driving motor 13 is reversed, at the moment, the hemostatic cotton 8 can rise according to the principle, when the timer 23 reaches the set rated time interval again, the hemostatic cotton 8 can be lowered in the same way to compress the radial artery puncture hole of the patient, the effect of timed relaxation compression can be realized, the problem that the skin cannot breathe due to long-time compression is avoided, and the wound healing of the patient is facilitated;

Before the hemostatic cotton 8 is loosened at fixed time and the radial artery is compressed again, the two reducing motors 30 are started, the driving shafts of the reducing motors 30 drive the rectangular blocks 29 to rotate, then the rectangular blocks 29 rotate to drive the pressing rollers 7 to rotate, the hemostatic cotton 8 stained with blood on one of the positioning rollers 25 moves and is slowly wound on the other positioning roller 25, the hemostatic cotton 8 directly stained with blood is completely wound on the double faced adhesive tape 49, the hemostatic cotton 8 which is originally used for compressing the blood of the radial artery puncture Kong Zhanran of a patient can be rotated and adjusted, the blood stained area can be rotated to other positions, the clean part of the hemostatic cotton 8 is compressed again on the radial artery of the patient, bacteria adhesion on wounds can be reduced, and thus, the wound healing of the patient is further facilitated, the second L-shaped frame 6 can drive the connecting piece 33 and the sliding piece 32 to slide in the fixed groove 31 and stretch the return spring 34, meanwhile, the rectangular block 29 can slide out of the rectangular groove 28, then the hemostatic cotton 8 is pulled to release the sleeve of the round shaft 27 by the round hole 26, the pressing roller 7 and the hemostatic cotton 8 can be detached from the first L-shaped frame and the second L-shaped frame 6, then the miniature electric push rod 47 is started, the driving end of the miniature electric push rod 47 shortens and drives the second hemispherical body 48 to move, at the moment, one of the first hemispherical bodies 46 can slide downwards due to gravity, the support of the two positioning sheets 45 to the positioning roller 25 can be released, finally the positioning roller 25 can be peeled off from the pressing roller 7 by horizontally pulling the positioning roller 25, finally a new positioning roller 25 is mounted on the pressing roller 7 according to the principle, one end of the hemostatic cotton 8 is adhered to the double-sided adhesive 49 on the other positioning roller 25, the hemostatic cotton 8 is convenient to replace, so that the radial artery hemostatic compressor is convenient to recycle;

In addition, when the patient penetrates the limbs after the puncture is completed into the positioning opening 2, the servo motor 40 is started, so that the bidirectional screw rod 36 rotates, the two second nuts 37 drive the positioning pieces 38 to be close to each other, the two sides of the limbs of the patient can be conveniently limited, the limbs of the patient are prevented from shifting to the two sides when hemostasis by compression is performed, and the stability of the radial artery hemostasis compressor in use is improved.

The foregoing description is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical solution of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
