A kind of concealed disposable safe blood taking needle
Technical field
The present invention relates to technical field of medical instruments, a kind of concealed disposable safe blood taking needle.
Background technology
The maximum deficiency that the blood taking needle of prior art in use exists is poor stability, the blood taking needle needle point being finished is made to be completely exposed outside, not only cause secondary environmental pollution, there is also the potential danger to other people unexpected injury and infection, solve currently without good way.
Summary of the invention
The technical assignment of the present invention is to solve the deficiencies in the prior art, it is provided that a kind of new-type concealed disposable safe blood taking needle.
The technical scheme is that and realize in the following manner, its structure is made up of front needle handle, rear needle handle and needle body, needle body is arranged among front needle handle and rear needle handle by Shooting Technique, the left end of needle body is machined with needle point, needle point is positioned among front needle handle, the right-hand member of needle body is provided with disconnecting prevention structure, and disconnecting prevention structure is arranged among rear needle handle, is linked together by even muscle between front needle handle and rear needle handle.
Described concealed disposable safe blood taking needle, even the length of muscle stretches out the length of needle cap slightly larger than needle point.
Described concealed disposable safe blood taking needle, disconnecting prevention structure is the combination of one or both shapes of annulus, crotch or triangle.
Section in the middle of described concealed disposable safe blood taking needle, needle cap and needle handle is cross or circle.
The concealed disposable safe blood taking needle of the present invention has a beneficial effect highlighted below: 1) simple in construction, easy to use;2) use the mode hiding needle point that the needle point after using is processed, there is good anti-secondary pollution and the beneficial effect of anti-unexpected injury.

Fig. 3 is the structural representation after blood taking needle uses.
Labelling in accompanying drawing represents respectively: needle point 1, front needle handle 2, needle body 3, even muscle 4, rear needle handle 5, anti-drop device 6.
Detailed description of the invention
Below in conjunction with the accompanying drawings the concealed disposable safe blood taking needle of the present invention is described in further detail.
The concealed disposable safe blood taking needle of the present invention, its structure is made up of front needle handle, rear needle handle and needle body, needle body is arranged among front needle handle and rear needle handle by Shooting Technique, the left end of needle body is machined with needle point, needle point is positioned among front needle handle, the right-hand member of needle body is provided with disconnecting prevention structure, and disconnecting prevention structure is arranged among rear needle handle, is linked together by even muscle between front needle handle and rear needle handle.
Described concealed disposable safe blood taking needle, even the length of muscle stretches out the length of needle cap slightly larger than needle point.
Described concealed disposable safe blood taking needle, disconnecting prevention structure is the combination of one or both shapes of annulus, crotch or triangle.
Section in the middle of described concealed disposable safe blood taking needle, needle cap and needle handle is cross or circle.
Embodiment
The using method of concealed disposable safe blood taking needle is as follows:
1) rotating against simultaneously and advance front needle handle and rear needle handle, even muscle is wrapped on needle body, and the left end of needle point needle handle in the past is protruding, carries out blood sampling operation;
2) blood sampling operation terminates, and reversely rotates until even muscle fractures by relative with rear needle handle for front needle handle, and the most reversely front needle handle of tractive and rear needle handle stashes among needle handle before allowing needle point retract, and company's muscle this blood taking needle of protruding expression fractureed had used.
Even muscle primarily serves the newness degree of length of needlepoint positioning action and blood taking needle.
The known technology of those skilled in the art it is in addition to technical characteristic disclosed in the description of the present invention.
