Only.
The utility model is due to using above-mentioned structure, and compared with prior art, acquired technological progress is:
(1) first wing of the utility model is connect with the second wing tearable, and after tearing separation, the first wing is to biography
The limitation in dynamic portion is eliminated, so that anti-stab traumatic part coats blood taking needle under the driving of power part, so as to effectively avoid medical matters people
Member is occurred by the accident of needlestick injuries；
(2) main body of the Anti-stabbing mechanism of the utility model be hollow cylindrical, open up thereon for the first wing rotation and
The second notch, the first notch of sliding, the hollow part of blood taking needle drawing-in main body, the both ends of elastomeric element are respectively and in main body
Flange and connector are connected, and work as tearing due to adopting the structure in tensional state in the connection of the first, second wing
The first, second wing is separated, so that main body coats rapidly syringe needle under the driving of elastomeric element, it is easy to operate, quick；
(3) main body inner wall of the Anti-stabbing mechanism of the utility model is equipped with elastic slice, is formed with and elastic slice phase on connector
The groove of cooperation；There is main body elastic slice to be placed in the groove, constitute the lock of relative motion between the main body and connector
Only；Using this structure and connection type, after main body can be made to coat blood taking needle, under the influence of external force, elastic slice is difficult because of elastic deformation
It is skidded off from groove, to strengthen because accidentally touching Anti-stabbing mechanism, causes syringe needle exposed outside, it is ensured that medical worker's
Safety, prevents secondary pollution caused by being wounded by stabbing.
To sum up, the utility model has the spy for preventing medical worker to be wounded by stabbing in the state of exposed in the syringe needle of blood taking needle
Point, and it is easy to operate, quick, practical, it is suitable for medical worker's blood sampling operation.
