Further, described slipper bracket top is provided with chute, bottom is provided with holder, the relative holder of described chute is obliquely installed, the cylindrical shell of described needle holder is located in described chute, syringe needle is positioned at the lower one end of described chute, by mobile described slipper bracket adjustment with thrust angle when keeping described needle holder to take a blood sample.
Further, described chute is arcuate furrow, and the cylindrical shell of arc radius and described needle holder matches.
Further, described holder lower surface is arcwall face, by this arcwall face, described holder is fixed on human skin surface.
The venous blood collection needle holder adopting said structure to arrange, has the following advantages:
Needle holder cylindrical shell of the present utility model is provided with and holds the wing and empennage, hold cylindrical shell by the end wing and empennage, make moving back pipe and sending pipe to be more prone to operation of vacuum test tube, ensure that the smooth of blood collection procedure and safety, blood sampling success rate can be improved.
Cylindrical shell of the present utility model is provided with slipper bracket, by slipper bracket adjustment with keep needle holder take a blood sample time thrust angle, can patient suffering be alleviated, protection patient vessel, raising comfort level.
This utility model can significantly reduce blood sampling contingency occurrence probability, alleviates work load when medical personnel take a blood sample.

Detailed description of the invention
For further setting forth this utility model for the technological means that reaches predetermined technique object and take and effect, below in conjunction with accompanying drawing and preferred embodiment, structure of the present utility model, feature and effect are described in detail as follows.
Venous blood collection needle holder described in the present embodiment, structure is as shown in Fig. 2, Fig. 3, Fig. 8, Fig. 9, specifically comprise cylindrical shell 1, cylindrical shell 1 front end is provided with spiral interface, is provided with syringe needle 2 by spiral interface, and the rear end of cylindrical shell 1 is provided with the empennage 3 protruding cylindrical shell 1, the front end of cylindrical shell 1 is also provided with the end wing 4 protruding cylindrical shell 1, hold cylindrical shell 1 by the end wing 4 and empennage 3, facilitate nurse to point when pushing pipe and prop up formation with joint efforts, make moving back pipe and sending pipe to be more prone to operation of vacuum test tube.
As shown in Figure 8, Figure 9, the end wing 4 is made up of 2 wing plates be oppositely arranged, and wing plate is curved, semilune or petal, and preferred Fig. 8's is petal.
The structure of the end wing 4 and empennage 3 can be different, and such as shape, size are not identical, also can structure identical.Preferably, wing plate and finger contact face are provided with projection or groove, anti-skidding effect can be played.
The end wing 4 and empennage 3 the widest part are 1-1.5cm, the size d namely in Fig. 8, Fig. 9.
Cylindrical shell 1 length is 6-6.5cm, the size b namely in Fig. 5, Fig. 6.
A code requirement is had in needle holder use procedure, after syringe needle 2 is installed into the spiral interface of cylindrical shell 1 front end, syringe needle 2 thrusts the inclined-plane of end towards being just in time positioned at two empennage 3 middles, and in this utility model, syringe needle 2 thrusts the inclined-plane of end towards also will just in time be positioned in the middle of two end wings 4.
As shown in Figure 10, Figure 14, needle holder is also supporting is provided with slipper bracket, and this slipper bracket is arranged on cylindrical shell 1, between the end wing 4 and empennage 3, thrusts angle when keeping needle holder to take a blood sample by slipper bracket.
Slipper bracket top is provided with chute 5, bottom is provided with holder 6, chute 5 relatively holder 6 is obliquely installed, as shown in Figure 11, Figure 12, Figure 13, the cylindrical shell 1 of needle holder is located in chute 5, syringe needle is positioned at the lower one end of chute 5, thrusts angle when keeping needle holder to take a blood sample by slipper bracket.
Chute 5 is arcuate furrow, and the cylindrical shell 1 of arc radius and needle holder matches.Preferably, chute 5 is the loop of half-surrounded, both can slide when cylindrical shell 1 is located in chute 5, can not depart from chute 5 easily again.
Holder 6 lower surface is arcwall face, by this arcwall face, holder 6 is fixed on human skin surface.Because patient's arm is fat or thin not etc., there is individual variation, so the radius of this arcwall face is moderate, not easily too small, can use on most patient arm like this.
