The utility model content

The purpose of this utility model just provides the aseptic tourniquet of a kind of slide-and-lock, uses difficult standard inconvenient to solve existing tourniquet, and sterilization is difficult for.Improve the reliability of locking and hemostasis, rationally take limbs area change comfort level.Improve operating efficiency, reduce patient's burden.

This utility model is achieved in that the aseptic tourniquet of a kind of slide-and-lock, comprises sebific duct and slide lock; Described slide lock is to have two perforation lockholes that are set up in parallel, are used for locking described sebific duct in lock body.

Two described perforation lockholes in the described slide lock comprise a circular hole and a flat round hole.

The internal diameter of described circular hole is identical with the pipe external diameter of described sebific duct, and the girth of described flat round hole is less than the pipe outer perimeter of described sebific duct.

The two ends of described sebific duct are tapered end, and sebific duct is circular tube shaped under the natural form, and the sebific duct of (skin contact) becomes flat belt-like during locking state.

This utility model is the aseptic tourniquet of a kind of slide-and-lock, and its scientific structure design is succinct, meets the organization of human body characteristic, uses easy and simple to handlely, light, only need gently draw sebific duct to lock, and reliable lock, and coupling mechanism force can be regulated arbitrarily on a large scale; It is reasonable that locking face takies people's bulk area, both improved the comfort level of using, and can reduce again the impact on the puncture procedure face; When loosening, gently draw the sebific duct of slide lock one end, the tourniquet of can loosening, firmly little, speed is fast, and is easy and simple to handle; Sebific duct in this tourniquet adopts medical latex tube, slide lock adopts ABS plastic, thereby can carry out the sterilizing operation of standard, realizes the cleaning sterile of Production and Packaging, meet the requirement of Ministry of Public Health two class medical apparatus and instruments standards, the generation of effectively having stopped cross infection and nosocomial infection's situation; As disposable tourniquet, also can with simultaneously Production and Packaging of disposable transfusion device, both be conducive to the use at first aid scene, the scale of the hospital that is more convenient for is used.

This utility model is rational in infrastructure, and the limbs area occupied is little, and is easy for operation, and compensating roller simple, dependability is high, also can repeatedly sterilize, and avoids cross infection or nosocomial infection.

Description of drawings
