Problems solved by technology

The current binding hemostasis method used in this field is to bind with a rubber tube. Due to the fast operation of the rubber tube, it is generally used in the operation process to bind the upstream of the bleeding site to seal the blood flow of the upstream blood vessel, but the binding is not possible. It lasts for a long time, and the tightness of the bundle can only be felt. Once the tightness is not suitable, you need to repeat the operation once

Abstract

The invention relates to an upper arm tourniquet for the ulna / radius fracture operation. A tourniquet needs to be bound on an upper arm in the forearm fracture operation process in the orthopaedics department; at present, the binding of a rubber pipe applied to the field can not last for a long time, the tightness degree can be known only through feeling, and once the tightness degree is not appropriate, the operation needs to be repeated again. The upper arm tourniquet comprises a tourniquet body which is a high-resillence strip-shaped soft belt made of polyurethane, and a plurality of vent holes are formed in the tourniquet body. The upper arm tourniquet further comprises a hard adjustment plate, an inflation bag and an extrusion sacculus, wherein the hard adjustment plate is in an arc shape, long groove holes are formed in the two ends of the hard adjustment plate respectively, the tourniquet body is in an annular shape and penetrates through the long groove holes, the inflation bag is arranged between the tourniquet body and the hard adjustment plate and is connected with the extrusion sacculus through an inflation hose, and a ball valve is arranged on the extrusion sacculus. The upper arm tourniquet is high in binding and detaching speed, and can be used for long-time continuous hemostasis especially the ulna / radius fracture operation in the orthopaedics department.

Description

technical field [0001] The invention relates to an orthopedic medical instrument, in particular to an upper arm tourniquet for ulnar / radius fracture surgery whose tightness is adjusted by pressure. Background technique [0002] In orthopedic forearm fractures, if both the ulna and the radius are fractured, it needs to be fixed with steel pins or plates after surgery. During the operation, in order to prevent blood loss, a tourniquet needs to be tied on the upper arm. The current binding hemostasis method used in this field is to bind with a rubber tube. Due to the fast operation of the rubber tube, it is generally used in the operation process to bind the upstream of the bleeding site to seal the blood flow of the upstream blood vessel, but the binding is not possible. It lasts for a long time, and the tightness of the bundle can only be felt. Once the tightness is not suitable, you need to repeat the operation once. Contents of the invention [0003] The technical proble...
