Detailed Description
In order to facilitate understanding of the purpose, technical solution and effect of the present invention, the present invention will now be described in further detail with reference to the embodiments.
As shown in fig. 1 to 5, the utility model discloses a puncture-proof type puncture needle, it includes:
a puncture needle body 1 which comprises a needle body 11, a needle seat 12 and a liquid guiding hose 13;
the puncture-preventing component 2 comprises a needle handle 21, a protective sleeve 22 arranged at the tail end of the needle handle 21 and a blocking component 3 arranged at the upper end and the lower end of the front end of the needle base 12;
the needle handle 21 is movably connected with the needle seat 12;
the protecting sleeve 22 is sleeved on the liquid guiding hose 13, and the protecting sleeve 22 slides to the tail end of the needle base 12 to be connected with the limiting component 4 at the tail end of the needle base 12.
The utility model provides a prevent stabbing type pjncture needle of this application embodiment, its in-process of using:
when the medical staff pulls out the needle, the medical staff holds the needle handle 21 and pushes forwards with force, the connecting band 14 between the needle handle 21 and the needle base 12 is rapidly broken, and the needle handle 21 passes through the stop ring 31 at the front end and moves forwards until the puncture needle is covered; at this time, the positioning ring 23 at the tail end of the protecting sleeve 22 is connected with the limiting ring 41 at the tail end of the needle base 12 through magnetic adsorption to achieve the purpose of quick positioning;
