Background

Intravenous infusion technology is one of the most common, most direct and safest clinical treatments. As the infusion needs to be injected from the vein, an infusion needle hole is inevitably formed on the body surface of a patient. After the patient finishes transfusion, because the transfusion needle hole is difficult to be quickly coagulated, doctors require sick and weak patients or non-professional relatives and friends to press the needle hole, and if the needle hole is not pressed in place or the pressing time is short, the phenomena of continuous bleeding and bruise of the transfusion needle hole and potential safety hazards easily occur. However, in the process of pressing the infusion needle hole, the movement of the patient or the medical staff is limited, and if the patient is anxious to relieve the hands, wear, arrange living goods and wear, the action of pressing the infusion needle hole brings serious inconvenience.

The existing similar hemostatic plaster has an unsatisfactory pressing effect and cannot help a needle opening to quickly coagulate blood because an infusion needle pierces skin and a blood vessel, and the vein still conveys blood continuously at a source although the needle opening of the skin or the blood vessel is pressed, so that a wound cannot be quickly contracted and coagulated. Therefore, the optimal situation is to act on the skin, the puncture opening of the blood vessel and the proximal end and the distal end of the blood vessel simultaneously to temporarily block or slow down the flow velocity of the section of the blood vessel, so as to achieve faster blood coagulation.
