Description

Medical tourniquet

This utility model belongs to a kind of medical appliance, is a kind of medical tourniquet specifically.

At present, do not find the tourniquet of the design's version as yet.

The purpose of this utility model is for solving the problem of above-mentioned existence, possesses special-purposely and provide a kind of, and can alleviate the part and too reins in pressure, reaches the medical tourniquet of best haemostatic effect.

The technical solution of the utility model is: adopt one to be flat-shaped drawstring body, it has on drawstring one in device and is overlapped by clip in the open slot of a side and the flute profile paw is housed respectively and has the movable pressing board of stretching tongue, connect by shared bearing pin, the other end of movable pressing board also is provided with the pin that compresses that contacts with paw and is hinged on clip by axle by the supermedial slotted eye of paw and puts the clip device of forming; Make an end of drawstring be provided with the anti-avulsion card, the other end is fixed on the kayser that has button, and matches and constitute an annular tourniquet with the tongue of stretching that the clip device has.

The characteristics that the utlity model has:

1, employing is flat-shaped drawstring body, causes the pressure of reining in of local organization in the time of can significantly reducing operation, reaches best haemostatic effect.

2, the drawstring body is made by nylon ribbon and colloid, can prevent to wear out, and improves the service life of tourniquet.

But 3, easy and simple to handle, the quick regulated at will size of ending pressure.And having possessed special-purpose medical apparatus, it is not only applicable to hospital, also can be used for field army, factories and miness, school etc. as the external hemostasis instrument under the outer situation of determining.

Embodiment is further described below in conjunction with accompanying drawing:

Fig. 1 is the topology view of medical tourniquet.

Fig. 2,3 is the section of structure of kayser.

By shown in Figure 1, medical tourniquet, it adopts and is flat-shaped drawstring 2, having on drawstring 2 one in device is overlapped in 3 one open slots of surveying by clip flute profile paw 4 is housed respectively, with have the movable pressing board 6 of stretching tongue, two bodies are cooperated by common bearing pin 6 connect, the other end of movable pressing board 7 also is provided with the pin 12 that compresses that contact with paw 4 and forms and be hinged on clip by axle 5 by paw 4 supermedial slotted eyes and overlap clip device on 3.Compressing pin 12 is to rely on the diaxon head end to be overlapped on the inclined-plane of pressing card 4.End by drawstring 2 is provided with anti-avulsion card 1, and the other end is fixed on the kayser 8 that has button.The draw-in groove of stretching on the tongue 9 by claw 21 in kayser 8 jacks and clip device 11 matches, and constitutes an annular tourniquet.

Fig. 2,3 shows the overall structure of kayser.It is two pairs of cavitys that projection forms that distribute by in the lock housing 14, and cavity is overlapping to be provided with two buttons 16, makes the elasticity that has on button 16 bodies collude 20 and is stuck on the curved end of projection, makes with two claws 21 of side corresponding.Be connected with bar shaped teeth 15 between the wherein a pair of projection, and the pressing plate 13 have the drawstring patchhole be installed, make the guide table 18 that has on the pressing plate 13 and alignment pin 17 jack end, by screw 19 fixedly connected formations corresponding to lock housing 14 on lock housing 14 recessed end limits.

The interior stamen of drawstring 2 is a nylon ribbon, and extexine is that gelatinous layer is made.

During use, kayser 8 is directly inserted stretching on the tongue 9 of clip device, the claw 21 in the bayonet lock 8 is pinned with draw-in groove 11 engagements of stretching on the tongue 9, grasp the clip device, traction drawstring 2 gets final product.Since the guide table 18 that has on the kayser 8 with stretch tongue 9 on gathering sill 10 and 17 spacing cooperations of alignment pin, can prevent to stretch into excessive or swing and cause the malfunctioning of kayser.
