In addition to the implementation, the utility model also has following working method, shown in Figure 1:
The utility model, the first needle wing 21 and the second needle wing 22 and the third needle wing 31 and the 4th needle are taken out before puncturing for patient
For the wing 32 originally to merge position, nurse, which can close up two groups of needle wings, has pinched that (i.e. the first needle wing 21 and the second needle wing 22 are affixed, third
The needle wing 31 and the 4th needle wing 32 are affixed), facilitate nurse to control and puncture direction, after puncture, nurse is directed to patient's pinprick oozing of blood
Situation, fixes the first needle wing 21 and the second needle wing 22 on the other hand, the other hand by the third needle wing 31 and the 4th needle wing 32 along needle stalk 12 to
It is pushed forward, reuses adhesive plaster and fix two groups of needle wings respectively, achieve the purpose that prevent puncture needle eye oozing of blood.
When machine under patient, when nurse pulls out needle, as needle stalk 12 shrinks back, the needle wing 31 and 32 is gradually forward.At this point, needle stalk is convex
The rear side of inner wall of second sleeve structure 33 can be stuck in by playing 121, so that slide assemblies stop sliding；And semicircle flexible glue body 4
It is placed on the tip of needle stalk 2；Since needle stalk 12 has retreated on rear side of magnet 51 and 52, magnet 52 loses the blocking of needle stalk 12, magnet 52
It is adsorbed by magnet 51；At this point, magnet 52 plays the role of blocking pinprick.Magnet 52 plays the role of closing needle point at this time.
The above is only the utility model preferred embodiments, are not intended to limit the embodiments of the present invention and protection
Range should can appreciate that all with the utility model specification and diagramatic content institute to those skilled in the art
The equivalent replacement made and obviously change obtained scheme, the protection scope of the utility model should all be included in
It is interior.
