A kind of winding ruins pattern disposable safe blood taking needle
Technical field
The present invention relates to technical field of medical instruments, specifically a kind of winding ruins pattern 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 winding ruins pattern 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 on by Shooting Technique among front needle handle and rear needle handle, the left end processing of needle body has needle point, needle point to be positioned among front needle handle, and the right-hand member of needle body is provided with disconnecting prevention structure, disconnecting prevention structure is arranged among rear needle handle, being interrupted between front needle handle and rear needle handle and linked together by needle body, the left end of front needle handle is provided with ruins pin round platform, ruins pin frustum cone side and is provided with Tibetan pin hole.
Pattern disposable safe blood taking needle is ruined in described winding, and the width being interrupted between front needle handle and rear needle handle stretches out the length of front needle handle slightly larger than needle point.
Pattern disposable safe blood taking needle is ruined in described winding, and disconnecting prevention structure is the combination of one or both shapes of annulus, crotch or triangle.
Pattern disposable safe blood taking needle is ruined in described winding, and the section in the middle of needle handle is cross or circle.
Pattern disposable safe blood taking needle is ruined in the winding of the present invention, has beneficial effect highlighted below: 1) simple in construction, easy to use;2) adopt the hiding mode ruining type that is wound around that the needle point after using is processed, there is good anti-secondary pollution and the beneficial effect of anti-unexpected injury.

Fig. 2 is wound around ruining pattern disposable safe blood taking needle and uses status architecture schematic diagram;
Fig. 3 is wound around ruining the structural representation after type ruined by pattern disposable safe blood taking needle.
Labelling in accompanying drawing represents respectively: pinprick 1, needle point 2, ruin pin round platform 3, needle body 4, front needle handle 5, rear needle handle 6, anti-drop device 7.
Detailed description of the invention
Below in conjunction with accompanying drawing, the winding of the present invention is ruined pattern disposable safe blood taking needle to be described in further detail.
Pattern disposable safe blood taking needle is ruined in the winding of the present invention, its structure is made up of front needle handle, rear needle handle and needle body, needle body is arranged on by Shooting Technique among front needle handle and rear needle handle, the left end processing of needle body has needle point, needle point to be positioned among front needle handle, and the right-hand member of needle body is provided with disconnecting prevention structure, disconnecting prevention structure is arranged among rear needle handle, being interrupted between front needle handle and rear needle handle and linked together by needle body, the left end of front needle handle is provided with ruins pin round platform, ruins pin frustum cone side and is provided with Tibetan pin hole.
Pattern disposable safe blood taking needle is ruined in described winding, and the width being interrupted between front needle handle and rear needle handle stretches out the length of front needle handle slightly larger than needle point.
Pattern disposable safe blood taking needle is ruined in described winding, and disconnecting prevention structure is the combination of one or both shapes of annulus, crotch or triangle.
Pattern disposable safe blood taking needle is ruined in described winding, and the section in the middle of needle handle is cross or circle.
Embodiment
It is wound around the using method ruining pattern disposable safe blood taking needle as follows:
1) rotating against the front needle handle of propelling and rear needle handle simultaneously, make both merge, the left end of needle point needle handle in the past is protruding, can carry out blood sampling operation;
2) blood sampling operation terminates, and reversely rotates relative with rear needle handle for front needle handle and tractive, extracts, be then inserted in the Tibetan pin hole that front needle handle left end ruins pin frustum cone side in needle body needle body in the past;
3) before rotating, needle handle is wrapped in by needle body and ruins on pin round platform, it is achieved ruin type purpose completely.
The known technology of those skilled in the art it is except technical characteristic disclosed in the description of the present invention.
