Abstract

The utility model relates to a medical device, in particular to a self-choking tourniquet which compresses an elastic bandage through a pressing edge on a clamp, and consists of a sliding clamp body, a clamp bolt, the elastic bandage and a check block, wherein the sliding clamp body is a wedged hollow cavity body, and the elastic bandage penetrates through the center of the sliding clamp body; an underlay block is arranged on the elastic bandage; one end of the elastic bandage is connected with the bottom of the clamp bolt, the clamp bolt is a wedged shrapnel, and the pressing edge is arranged at the front end of the wedged shrapnel; the other end of the elastic bandage is connected with the check block; and the clamp bolt can be clamped in the hollow cavity of the sliding clamp body, and can be separated from the sliding clamp body through pressing a pressing handle on the clamp bolt. The tourniquet adopts the sliding clamp body in the wedged cavity body structure, and is provided with the pressing edge on the clamp bolt, so when the elastic bandage is enabled to be tightened around the arm of a patient, the pressing edge on the clamp bolt compresses the elastic bandage, and the elastic bandage cannot slide, therefore, the compression mode is simple and effective, and the service life of the product is also prolonged while the production cost is lowered.

Description

The self-clamping type tourniquet

Technical field

This utility model relates to a kind of medical apparatus and instruments, particularly a kind of self-clamping type tourniquet that compresses the degree of tightness binder through the pressure rib on the dop.

Background technology

When patient transfuses blood or infuses, adopt arm stretch tight bundles of rubber tube to transfusion more in hospital, preventing venous return, but stretch tight when pricking with rubber tube, need doctor or nurse that rubber tube is tied tight and tied a knot, operation is very inconvenient; The rubber tube diameter is less, reins on patient's arm, can make patient that very uncomfortable sensation is arranged.In addition, Chinese patent ZL200520023331.3 discloses a kind of tourniquet, though this tourniquet can replace rubber tube; Can be easily to patient's arm bundle that stretches tight, but this tourniquet structure mountain more complicated, production cost is high; And it utilizes the card falcon that the degree of tightness binder is compressed, and card falcon and degree of tightness binder contact area are less; Unit are is stressed just bigger, and the card falcon damages easily, so service life is shorter relatively.

The utility model content

This utility model technical problem to be solved provides a kind of structural reduction exquisiteness, production cost is low, and it is comfortable that sufferer is felt, the self-clamping type tourniquet of long service life.

For solving the problems of the technologies described above, this utility model is realized as follows: the described self-clamping type tourniquet of this utility model is made up of card body, block tongue, degree of tightness binder, pad piece and block; The card body is a wedge shape cavity body; Which is provided with and wear trough of belt and draw-in groove; The degree of tightness binder passes from card body central authorities through wearing trough of belt, and the card body can slidably reciprocate on the degree of tightness binder, and the degree of tightness binder is also fixing to form the pad piece near the inwardly folding certain-length of block tongue one end; One end of degree of tightness binder is connected with the block tongue bottom, and block tongue is a wedge shape shell fragment, has elasticity, and the central authorities on surface are provided with a card rib above that, and front end is provided with the pressure rib, and the rear end is provided with pressure handle; The degree of tightness binder other end is connected with block; Block tongue can snap onto in the cavity of card body, sees Fig. 2, and the card rib during chucking on the block tongue embeds in the draw-in groove of card body, presses down the pressure handle on the block tongue, and block tongue is broken away from from the card body; The degree of tightness binder is tightened, and makes the pressure rib on the block tongue compress the degree of tightness binder, prevents that the degree of tightness binder from sliding, and sees Fig. 3.

The pad block structure is preferred but be not limited to degree of tightness binder autofolding structure, and its structure can also be fixed in the additament on the degree of tightness binder for sponge block, rubber blanket, cotton liner etc.

The good effect of this utility model is: this utility model adopts the card body of wedge cavities body structure; And on block tongue, be provided with the pressure rib; When the degree of tightness binder was tightened on patient's arm, the pressure rib on the block tongue compressed the degree of tightness binder, and it can not slided; This to compress mode simply effective, when having reduced production cost, also prolonged the service life of product.Adopt the pad block structure, alleviated when tourniquet tightens up the compressing of buckle structure to patient skin, the pad block structure is preferably the autofolding structure, and is simple in structure, easy to use.

The specific embodiment

To shown in Figure 3, the described self-clamping type tourniquet of this utility model is made up of card body 1, block tongue 2, degree of tightness binder 3 and block 4 like Fig. 1; Card body 1 is a wedge shape cavity body; Which is provided with and wear trough of belt 5 and draw-in groove 6; Degree of tightness binder 3 passes from card body 1 central authorities through wearing trough of belt 5; Preferably, degree of tightness binder 3 is also fixing to form pad piece 10 near the inwardly folding certain-length of block tongue 2 one ends, and card body 1 can slidably reciprocate on degree of tightness binder 3; One end of degree of tightness binder 3 is connected with block tongue 2 bottoms, and block tongue 2 is a wedge shape shell fragment, has elasticity, and the central authorities on surface are provided with a card rib 7 above that, and front end is provided with presses rib 8, and the rear end is provided with pressure handle 9; The degree of tightness binder other end is connected with block 4; Block tongue 2 can snap onto in the cavity of card body 1, sees Fig. 2, and the card rib 7 during chucking on the block tongue 2 embeds in the draw-in groove 6 of card body 1, presses down the pressure handle 9 on the block tongue 2, and block tongue 2 is broken away from from card body 1; Degree of tightness binder 3 is tightened, and makes the pressure rib 8 on the block tongue 2 compress degree of tightness binder 3, prevents that degree of tightness binder 3 from sliding, and sees Fig. 3.

Pad piece 10 structure optimizations but be not limited to degree of tightness binder 3 autofolding structures, its structure can also be fixed in the additament on the degree of tightness binder 3 for sponge block, rubber blanket, cotton liner etc.

The use of this utility model is: block tongue 2 is inserted chucking in the active card body 1, and zone circle of degree of tightness binder 3 formation this moment is enclosed within zone circle on patient's the arm; Twitch degree of tightness binder 3, make the binder patient's arm of tying tight, because the tying tight of binder; Block tongue 2 tail ends are tilted upward, and block tongue 2 front ends will be to pressing down, this moment, the pressure rib 8 of block tongue 2 front ends will compress degree of tightness binder 3; Make degree of tightness binder 3 keep tight state, thereby reach the effect of the patient's arm of tying tight.When degree of tightness binder 3 was tied tight, pad piece 10 pads had alleviated the sense of discomfort that buckle structure brings between patient skin and tourniquet.
