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.
