When using the compression apparatus, the fixing band 22 and the pressure regulating plate 1 are put on the arm of the patient, and the hemostatic pad 6 is aligned with the artery puncture point of the arm of the patient. Pulling the pull ring 10 then brings the support cap 9 and the toothed ring 12 vertically upwards and disengages the toothed ring 12 from the inner toothed ring 112. Subsequently, the support cap 9 is rotated forward by turning the pull ring 10, and the support rod 712, the fixing rod 711 and the screw 72 are rotated forward by the support cap 9. Then, the pressure plate 3 drives the guide rod 4 to move vertically downward under the driving of the screw 72.

Then the driving gear 132 drives the outer gear ring 131 to rotate the support ring 111 and the inner gear ring 112 slowly in the opposite direction, and then the inner gear ring 112 drives the gear ring 12 to rotate the support cap 9 slowly in the opposite direction. Subsequently, the support cap 9 drives the support rod 712, the fixing rod 711 and the screw 72 to rotate slowly and reversely. Then, the pressure plate 3 is driven by the screw 72 to carry the guide rod 4 vertically upwards slowly, so that the pressure plate 3 is gradually separated from the arm of the patient.

The radial artery hemorrhage pressing needs at least 15min, the pressing time is different due to different physiques of each person, partial patients with weak physique and easy bleeding need pressing for more than 30min, but long-time pressing causes discomfort of the patients, and the longer the pressing time is, the better the pressing time is.

Therefore, when the patient self-confirms hemostasis or presses for more than 15min, the pressure plate 3 can be controlled to move upwards slowly, and once the bleeding phenomenon still occurs at the artery puncture point of the arm of the patient, blood enters the hemostatic pad 6, so that the humidity of the hemostatic pad 6 is gradually increased. When the humidity in the hemostatic pad 6 is higher than the preset value of the humidity sensor 17, the controller 19 controls the extension end of the electric push rod 18 to extend. At this time, the supporting cap 9 drives the gear ring 12 to move vertically upwards under the pushing of the telescopic end of the electric push rod 18, and the gear ring 12 is separated from the inner gear ring 112. At the same time, the screw 72 remains stationary, thereby preventing the pressure plate 3 from continuing to move upward.

Then, the medical staff can replace the hemostatic pad 6 and drive the telescopic end of the electric push rod 18 to reset through the controller 19. Meanwhile, the pull ring 10 is rotated again to drive the support cap 9 to rotate forward, so that the pressure plate 3 abuts against the arm of the patient again and timely hemostasis is performed on the artery puncture point of the arm of the patient. Just because the difference in each patient's physique leads to also having the difference in its artery hemostasis required time, can avoid the situation further to worsen through above-mentioned setting, be convenient for in time handle.

Meanwhile, after the pressure plate 3 abuts against one end of the arm of the patient for a while, the patient can also control the forward and reverse reciprocating rotation of the output shaft of the forward and reverse rotating motor 14 at regular time, and the pressure plate 3 slowly moves vertically downwards or vertically upwards. Thereby avoiding the pressure plate 3 from tightly supporting the arm of the patient for a long time and further avoiding the situation that other blood vessels in the arm of the patient are not circulated.
