Abstract

The invention discloses a rack type finger root hemostasis belt which comprises a belt shaped second hemostatic belt. A locking device is arranged at one end of the second hemostatic belt, and a locking part is arranged at the other end of the second hemostatic belt; a rack is arranged on the locking part to be matched with a gear arranged inside the locking device; the hemostasis belt further comprises a first hemostasis belt, the first hemostasis belt is in a C shape, and the two ends of the first hemostasis belt are provided with branched hemostasis belts; the branched hemostasis belts at the two ends of the first hemostasis belt are arranged in a staggered mode; the edges of the first hemostasis belt and the branched hemostasis belts are provided with chamfers; the first hemostasis belt is composed of two layers of materials, the outer layer is made of PVC, and the inner layer making contact with skin of a patient is made of non-toxic elastic skin-friendly materials; the hemostasiseffect is ensured, and fingers of a patent are prevented from being damaged by excessive large binding pressure. A ratchet mechanism is adopted as a hemostasis belt locking mechanism, the hemostasisbelt is simple and reliable, and the hemostasis body can be effectively controlled to be tightened or loosened.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a rack-type finger root tourniquet. Background technique [0002] The tourniquet is a medical device used for emergency hemostasis in surgery or first aid. Its working principle is to achieve the purpose of hemostasis by applying pressure to compress blood vessels and blocking blood flow. Tourniquets currently widely used mainly include the following types: elastic type, inflatable (airbag) type, belt type, snap-on type, etc. [0003] Most of the elastic tourniquets used clinically are rubber strips or rubber tubes, which are narrow in width. When binding the wound, if the binding force is small, the hemostatic effect will not be achieved, and if the binding force is too large, it will cause soft tissue damage. In addition, the use of elastic tourniquets cannot accurately control the strength of banding, and banding for a long time may lead to tissue necrosis. [0004] Inflat...
