Description

The one tourniquet of saving oneself

Technical field

This utility model relates to a kind of medical apparatus and instruments, more specifically, relates to the one tourniquet of saving oneself.

Background technology

Nurse can be with the tourniquet of saving oneself of rubber tubulose to patient's arm bundle that stretches tight before transfusion for patient, to prevent the backflow of venous blood, this bundle mode that stretches tight needs doctor to tie a knot on patient's arm with rubber tube, tend to bring discomfort to patient, and have certain inconvenience taking off a hand operated meeting while saving oneself tourniquet.In some operation process, also need in the time piercing through, prevent venous return, with saving oneself, tourniquet can be made troubles in the time using and take off.In addition, China Patent No. is that the patent of CN201551361U discloses a kind of self-clamping type tourniquet of saving oneself, this binder of saving oneself on tourniquet is in the time tying patient's arm tight, due to the effect of tying tight of binder, can make the tail end of block tongue be upturned, block tongue front end will press down, and the pressure rib of block tongue front end will compress elastic bandage, make elastic bandage keep the state of tightening, thereby reach the effect of the patient's arm of tying tight.The compression mode that this patent realizes is simply effective, but this patent has tightly been simplified the compression mode to arm, also needs the tensioned state that loosens binder just can take off this tourniquet of saving oneself taking off when this saves oneself tourniquet, actual troublesome operation is not simplified.

Utility model content

This utility model is at least one defect overcoming described in above-mentioned prior art, the one tourniquet of saving oneself is provided, this tourniquet of saving oneself is simple to operate, the function that oneself can realize quickly and easily locking and take off, bring simplification effect to the operation of the aspects such as medication injections, easy to carry, particularly oneself can implement hemostasis in battlefield and field when injured, gain time for rescuing.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is:

The one tourniquet of saving oneself, comprise slip card, block tongue, elastic bandage and block, described slip card slip cap is loaded on elastic bandage, described elastic bandage is elastic webbing, described block tongue connects one end of elastic bandage, and block connects the other end of elastic bandage, and described slip card is connected with block tongue buckle, slip card after fastening and block tongue form Self-locking angle α, and described α is obtuse angle.

After slip card is connected with block tongue buckle, in the annulus through slip card, block tongue and elastic bandage composition of staff or other positions that need to stop blooding, or the position that need to stop blooding around human body fastens slip card and block tongue, make to need the position of hemostasis to be arranged in the annulus that slip card, block tongue and elastic bandage form.Tension elastic bandage, elastic bandage is tied tight trunk that human body need to stop blooding, the card of now sliding and block tongue form Self-locking angle α, the structure of Self-locking angle both sides and trunk laminating are closely, be positioned at this joint place in the elastic bandage of tight state, the resilience force of elastic bandage is pressed close to slip card and block tongue and trunk more, reaches self-locking.Only need one-handed performance elastic cord to make its tension can complete the operation of locking hemostasis.Acting as when anti-skidding card is free to slide on elastic bandage of described block comes off.

For the syndeton of make to slide card and block tongue simple, one side of described slip card is that vertical plane is transitioned into slope structure, described slope is provided with the threading groove that runs through slip card, described elastic bandage passes from slip card by threading groove, in use, this is saved oneself before tourniquet, slip card can slidably reciprocate by threading groove on elastic bandage, adjusts the elastic bandage belt length of required use according to the required metastomium penetrating.

In order to match and to reach self-locking with organization of human body, described vertical plane is provided with draw-in groove, described block tongue and elastic bandage junction are provided with connection handle, described connection handle downside is plane, described block tongue inserts draw-in groove inside and is connected with draw-in groove buckle, after described block tongue inserts in draw-in groove, the mild transition of plane and slope, and form Self-locking angle α.After this tourniquet of saving oneself is tied tight on trunk, the Self-locking angle that plane and slope form and the radian of trunk match, plane and slope are pressed on elastic bandage on trunk, there is resilience force in the elastic bandage of tightening, this resilience force furthers plane and slope in trunk, elastic bandage can not be got loose, and realizes auto-lock function.

In order better to realize being connected of block tongue and draw-in groove, described block tongue is provided with snap fit, in described slip card, is also provided with buckle, and described buckle is located in draw-in groove, and protruding from slip card outside through slip card, described buckle is provided with the groove matching with snap fit.Block tongue is inserted in draw-in groove process to snap fit to be slipped into and in draw-in groove, realizes block tongue and be connected with the buckle of slip card, need to make block tongue depart from slip card time, press the buckle that protrudes from slip card outside, by draw-in groove to pressing down, snap fit with exact separation, complete the action of unclamping of the tourniquet of saving oneself.

In order further to realize the hemostatic function of the tourniquet of saving oneself, described block is provided with link.In the time that needs carry out hemostasis to arm, after the tourniquet of this can being saved oneself is tied tight on arm, link is hung on to eminence and crosses shoulder above, thereby arm is lifted, further prevent blood backflow.

Compared with prior art, the beneficial effects of the utility model are:

This utility model save oneself slip card that tourniquet is provided with and the Self-locking angle of block tongue composition, can the needed by human body position of stopping blooding be tightened at elastic bandage, the structure of Self-locking angle and trunk compress the elastic bandage of tightening, and the resilience force of elastic bandage can be realized auto-lock function; In slip card, be also provided with buckle, press buckle and can realize separating of slip card and block tongue, this utility model is simple in structure, easy to operate, a hands can complete locking and the operation separating, for medical care precess brings convenience, be convenient for carrying simultaneously, can make emergent hemostasis instrument.
