In clinical practice, the water injection channel 11 is pre-filled with water, which may be saline. Water flows into the pressurizing pad 2 in the clamping seat 12 from the water injection channel 11 and is absorbed by the water-absorbent resin, the water-absorbent resin absorbs water and expands, the pressurizing pad 2 is bound on the wound of the patient by aiming at the puncture of the patient, and the tightness of the fixing band 3 is adjusted, so that the operation is simple. The pressurizing pad 2 for pressing the puncture point of the patient for hemostasis is replaced by a replaceable pressurizing pad 2 filled with water-absorbent resin particles, and a water injection port is arranged above the pressurizing pad 2. In consideration of the problem that the puncture point of a patient is over-compressed, the compression pad 2 filled with water-absorbent resin is replaced, so that blood at the puncture point can be absorbed, and the blood gradually swells to play a role in compressing the puncture point to stop bleeding; and when the water-absorbent resin reaches the critical point of the pressure of the puncture point, namely, the blood can be stopped, but the blood cannot be excessively pressed to the critical point of the vein, the blood cannot continuously flow outwards due to the stopped critical point, the water-absorbent resin stops sucking blood and swells, the pressure can be naturally maintained at the balance point, and the reasons of unsmooth blood circulation, hand swelling and the like caused by the pressed vein are avoided.
