Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, especially a kind of snap-fastener tourniquet.
Background technology
At present, people are generally to adopt one section rubber tube or rubber strip as tourniquet in the first aid hemostasis, rely on the elasticity compressing blood vessel of tourniquet to come block venous blood to reflux, and reach the hemostatic purpose.But such mode is not only unhygienic also wayward dynamics for medical worker, so the elasticity of tourniquet be difficult for to be adjusted, causes patient's anxiety easily, even the patient is tied tight because of local skin is excessive sense of discomfort occurs.Skilled inadequately as some medical personnel's technology, when knotting needs the wounded to stop blooding voluntarily more slowly or under special circumstances, all can influence haemostatic effect; And in the process of ungirding, cause puncture failure easily, increase patient's the misery and the probability of cross infection.
Summary of the invention
In order to overcome the deficiencies in the prior art, it is a kind of easy to use that this utility model provides, and elasticity is easily regulated, the significant snap-fastener tourniquet of haemostatic effect.
The technical scheme that its technical problem that solves this utility model adopts is: a kind of snap-fastener tourniquet, comprise elastic webbing, it is characterized in that: comprise fastener, block tongue and tail button, described fastener is a tubular, be provided with demarcation strip in the fastener, demarcation strip axially is provided with and fastener is divided into the elastic webbing chamber and the snap close chamber of the equal opening in two ends along fastener, snap close intracavity on the fastener is provided with latching device, block tongue can be installed in the snap close intracavity, and constitute dismountable clamping with latching device and cooperate, place, snap close chamber also is installed on the switching mechanism that block tongue is deviate from, elastic webbing is arranged in the elastic webbing chamber and constitutes slippage with the elastic webbing chamber and cooperates, one end of elastic webbing is installed with block tongue, and the other end is installed with the tail button, the long-pending opening greater than the elastic webbing chamber of described tail button.
Wherein, perisporium place, place, snap close chamber offers the switch window on the fastener, switching mechanism comprises Switch main body, Switch main body is the U-shaped structure, position-limit foot is extended in the opening both sides of Switch main body, Switch main body places in the switch window and is suitable with the switch window, constitutes spacing the cooperation towards the edge of snap close chamber side on the position-limit foot on the Switch main body and the switch window, and the end face of Switch main body towards the snap close chamber is provided with the piece that presses of protrusion.
In addition, offer slotted eye on the block tongue, the slotted eye place is installed with grip tab, a side and slotted eye inwall are fixed on the grip tab, be provided with the gap between other sides and slotted eye hole wall, grip tab and slotted eye fixedly side right side edge be provided with lock projections, in the time of in block tongue is arranged in fastener, the inwall in snap close chamber is provided with lock projections and forms the spacing spacing preiection that cooperates, and has above-mentionedly constituted described latching device.
Adopt technique scheme, adopted latching device and switching mechanism, when the needs block venous blood refluxes, only need elastic webbing is twined in corresponding hemostasis place, by latching device block tongue is connected on the fastener then, thereby realize the hemostatic function of tourniquet; When needs are untied tourniquet, only need the Switch main body in the push switch mechanism, then block tongue breaks away from from fastener automatically, and elastic webbing unclamps, and venous blood recovers circulation.This use is novel can adjust elasticity at any time according to the patient body situation, and can tighten fast and unclamp hemostasis place, and easy to use, haemostatic effect is remarkable, is difficult for producing cross infection, long service life.
Of the present utility modelly further be set to: offer on the described grip tab for the guide groove that presses the piece motion on the Switch main body, this guide groove axially is provided with along block tongue.
Adopt technique scheme, when block tongue is connected on the fastener, guide groove be arranged so that on the Switch main body press piece can be smoothly from guide groove one end slippage to the other end, the mobile positioning action that played for block tongue, simultaneously also made things convenient for block tongue to be inserted on the fastener smoothly, avoid spacing preiection and the unexpected conflict of the lock projections on the block tongue on the fastener, thereby influence locking effect.
Of the present utility modelly further be set to: described elastic webbing is the flat elastic woven tape again.
Adopt technique scheme, the elastic woven tape of flat makes that in hemostasis the pressure arteries and veins area of elastic webbing is big, and the stressed of hemostasis place also disperseed, thereby has reduced patient's misery.
Below in conjunction with accompanying drawing this utility model is further described:
