The purpose of this utility model just provides a kind of blood donor of being suitable for and uses and tourniquet easy to use, comfortable, simple in structure, cheap.

The purpose of this utility model is achieved in that with the restraint zone to be agent structure, at the central part of restraint zone a tabletting is set.

In use, the tabletting position on the restraint zone is placed on blood donor's the cotton balls of blood drawing pinprick portion, behind the suitable fastening limbs restraint zone two ends are linked, like this under the contention effect of tabletting, just can reach and push identical hemostasis purpose with hands.

This utility model is simple in structure, and is easy to use, and the medical worker fastens this tourniquet to the blood donor after blood sampling, and blood donation personnel just can arbitrarily be done the thing of oneself, and needn't worry hemorrhage many adverse consequencess of bringing.

Be described in further detail this utility model below in conjunction with accompanying drawing.

Fig. 1 is a structural representation of the present utility model.

As shown in Figure 1, this utility model has restraint zone 1, and restraint zone 1 can be elastic cord or cloth matter band, preferably its width is arranged on 4-6cm, can avoid the narrow or wide discomfort of bringing to limbs of restraint zone like this.Make at the central part of restraint zone 1 and to fix a tabletting 2, this tabletting 2 can be hard plastic sheet, sheet metal, wood chip or hard paper, and the shape of tabletting 2 can be a rectangle, square, but garden shape preferably, its diameter is preferably 20-25mm, and thickness is 1-3mm.Garden shape can avoid the tabletting corner angle to stimulate limbs, suitable diameter can both guarantee that tabletting was exactly by being pressed in hemorrhage pinprick position, can avoid excessive again and bring discomfort to limbs, tabletting 2 can not be blocked up, feel uncomfortable because make limbs like that equally, but tabletting 2 can not be too thin, otherwise can not form the effect that rigid planar does not just have tabletting.Fastening for ease of restraint zone, the termination of restraint zone 1 can be provided with connecting elements such as double buckle, bright button, but preferably adopt velcro 3, like this when fastening, first just the taking in the two ends of restraint zone can be formed the isostatic dead ring of exerting oneself, use more conveniently like this, simultaneously also help improving medical worker's work efficiency.
