Technical field

This utility model relates to technical field of medical instruments, specifically a kind of bending self-destructed disposable safe blood-taking needle.

Background technology

The maximum deficiency that the blood taking needle of prior art in use exists is poor stability, outside the blood taking needle needle point that uses is exposed to fully, not only cause secondary environmental pollution, also have the potential danger to other people unexpected injury and infection, do not have good way to solve at present.

Summary of the invention

Technical assignment of the present utility model is to solve the deficiencies in the prior art, and a kind of new-type bending self-destructed disposable safe blood-taking needle is provided.

the technical solution of the utility model realizes in the following manner, its structure is by the hands handle, pin cap and needle body form, wherein, the left end of handle is provided with the pin neck and the pin cap links together, the centre of handle is provided with two parts before and after pin waist connecting handle, the right-hand member of handle is provided with backshank, needle body is through the pin cap, the pin neck, among pin waist and backshank, the left end of needle body is processed with needle point and is positioned among the pin cap, the right-hand member of needle body is processed with anti-decylization, be positioned at the right-hand member of backshank, section in the middle of handle is cross, the middle part of handle is provided with narrow slit, the pin waist is positioned in the middle of narrow slit.

Bending self-destructed disposable safe blood-taking needle of the present utility model has following outstanding beneficial effect: 1) simple in structure, easy to use; 2) adopt the mode of bending handle to carry out anti-secondary pollution and anti-unexpected injury to needle point, have well anti-pollution anti-injury security insurance effect.

Description of drawings

Fig. 1 is the main TV structure schematic diagram of blood taking needle;

Fig. 2 is the self-destruction status architecture schematic diagram after bending.

Labelling in accompanying drawing represents respectively: pin cap 1, needle point 2, pin neck 3, handle 4, narrow slit 5, pin waist 6, backshank 7, anti-decylization 8, needle body 9.

The specific embodiment

Below in conjunction with accompanying drawing, bending self-destructed disposable safe blood-taking needle of the present utility model is described in further detail.

bending self-destructed disposable safe blood-taking needle of the present utility model, its structure is by handle 4, pin cap 1 and needle body 9 form, wherein, the left end of handle 4 is provided with pin neck 3 and links together with pin cap 1, the centre of handle 4 is provided with pin waist 6 two parts before and after connecting handles, the right-hand member of handle 4 is provided with backshank 7, needle body 4 is through pin cap 1, pin neck 3, among pin waist 6 and backshank 7, the left end of needle body 4 is processed with needle point 2 and is positioned among pin cap 1, the right-hand member of needle body 4 is processed with anti-decylization 8, be positioned at the right-hand member of backshank 7, section in the middle of handle 4 is cross, the middle part of handle 4 is provided with narrow slit 5, pin waist 6 is positioned in the middle of narrow slit 5.

The using method of bending self-destructed disposable safe blood-taking needle is as follows:

1) rotation pin cap, twist off the pin neck, extracts needle point, the operation of taking a blood sample;

2) blood sampling EO, with the middle bending of handle, handle is divided into two sections, under the effect of lever, needle point being drawn among handle, because the anti-decylization of backshank can organize the needle body right-hand member to advance as among handle.

Anti-draw ring can be hook solid or other can prevent that needle body from entering the shape of handle.

Be the known technology of those skilled in the art except the disclosed technical characterictic of description of the present utility model.
