Air pressure type artery postoperation hemostat

Abstract

The invention discloses an air pressure type artery postoperation hemostat and relates to the technical field of medical care instruments. The hemostat comprises an upper tank and a lower ring, wherein the upper tank is divided into an inner circular cavity A and an outer ring cavity A, and the inner circular cavity A and the outer ring cavity A open downwards; a one-way air inlet valve is mounted on one side of the top face of the inner circular cavity A, and a one-way air release valve is mounted on the top face of the outer ring cavity A; a puller bolt is arranged at the center of the top face of the inner circular cavity A in a threaded connection mode, and the outer side of the puller bolt is sleeved with a telescopic sealing sleeve; the lower end of the upper tank and the upper end of the lower ring are sealed in a loose joint mode; the lower ring is divided into an inner circular cavity B and an outer ring cavity B, the inner circular cavity B and the inner circular cavity A are identical in size and are sealed in a butt joint mode, and the outer ring cavity B and the outer ring cavity A are identical in size and are sealed in a butt joint mode; a cotton pad is arranged in the inner circular cavity B and soaked with etamsylate. The air pressure type artery postoperation hemostat has the advantages that negative pressure of the outer ring cavity A enables the device to be tightly adsorbed to the body of a patient without a bandage, positive pressure of the inner circular cavity A is used for balancing blood pressure to reduce bleeding, operation is easy, and time is saved.

Description

technical field [0001] The invention relates to the technical field of hemostatic medical equipment. Background technique [0002] When a patient undergoes arterial surgery, postoperative hemostasis is very important. Arteries are different from veins in that they have higher blood pressure. Arterial bleeding, especially in larger arteries, has a violent and jet-like blood flow. Generally, finger pressure hemostasis or tourniquet hemostasis are used for hemostasis. When hemostasis, he should act quickly and thoroughly to prevent excessive blood loss. However, the medical staff need to press the patient's wound hard until the blood of the patient's wound coagulates and the soft tissue To connect is to let go. And this is a process that needs to go through for a long time. During this period, the patient needs to keep a still position to prevent the blood pressure at the wound from rising, destroy the coagulated blood clot, and prolong the pressing time of the medical staff;...

And this is a process that needs to go through for a long time. During this period, the patient needs to keep a still position to prevent the blood pressure at the wound from rising, destroy the coagulated blood clot, and prolong the pressing time of the medical staff; the medical staff must also Maintain a certain force to press the patient's wound, and cannot change hands or people, so it is also an unbearable process for medical staff
