Common remaining needle, either open or closed, the needle assembly of guiding puncture is from conduit tube component After middle extraction, needle point is an exposure to outer, and the medical staff for executing operation is possible to by needle pricks, it is also possible to will be infected with There is the needle point of patient blood to pollute.Discarded syringe needle is exposed in the environment simultaneously, be easy to cause environmental pollution, and it is hidden to there is safety Suffer from, therefore the remaining needle that anti-needle stabs type is occurred.
Utility model content
It is simple in sturcture, ingenious in design the utility model discloses a kind of new type of safe remaining needle, it is easy to operate, use peace Quan Xinggao.
The utility model is achieved through the following technical solutions:
A kind of new type of safe remaining needle, including protective case, infusion connector and anti-needle pierce protective device, the anti-needle thorn protection Device includes anti-needle thorn protective device front end, anti-needle thorn protective device middle section and anti-needle thorn protective device end, the anti-needle thorn Protective device front end, anti-needle thorn protective device middle section and anti-needle thorn protective device end are sequentially connected, the anti-needle thorn protection dress Set terminal bottom is equipped with ball, is inserted with needle stand in the anti-needle thorn protective device front end, the needle stand front is equipped with needle tubing, institute The lower end base for stating needle stand is inserted with calparine cap, and the anti-needle thorn protective device front end is inserted in again in infusion connector, described defeated It infuses connector front and is equipped with hose, the needle tubing passes through anti-needle thorn protective device front end and enters in hose, and the needle tubing protrudes from Hose is arranged with protective case on the infusion connector.
Preferably, the front inner wall of anti-needle thorn protective device front end is equipped with several annular protrusions, before the needle stand Outer wall is held to be equipped with several annular grooves, the protrusion matches with groove, and the infusion connector is equipped with corresponding retaining ring.
Preferably, the anti-needle thorn protective device middle section is connected to anti-needle thorn protective device terminus inner, is integrally presented small The big frustum of a cone down.
Compared with prior art, the utility model has the beneficial effects that
1, the infusion connector of the utility model is equipped with retaining ring, and the needle stand for being inserted into anti-needle thorn protective device front end is locked Tightly, after hose fully enters blood vessel, after extracting infusion connector, needle stand can fall off from anti-needle thorn protective device automatically, go forward side by side Enter in anti-needle thorn protective device, has no other manual operations, the automatic retracted of syringe needle can be realized, it is ingenious in design, it is easy to use;
2, after the needle stand of the utility model enters anti-needle thorn protective device, the ball phase clamping with bottom ensure that needle stand It is fixed in anti-needle thorn protective device, avoids the exposed of syringe needle, it is therefore prevented that medical staff substantially increases peace by needlestick injuries Quan Xing;
3, the utility model is simple in sturcture, ingenious in design, easy to operate, safe to use.

Specific embodiment
The present invention will be further described with reference to the accompanying drawing:
A kind of new type of safe remaining needle, including protective case 1, infusion connector 4 and anti-needle pierce protective device, and the anti-needle thorn is protected Protection unit includes that anti-needle thorn protective device front end 5, anti-needle thorn protective device middle section 8 and anti-needle pierce protective device end 9, described anti- Needle thorn protective device front end 5, anti-needle thorn protective device middle section 8 and anti-needle thorn protective device end 9 are sequentially connected, the anti-needle thorn 9 bottom of protective device end is equipped with ball 10, and the anti-needle, which pierces in protective device front end 5, is inserted with needle stand 6, before the needle stand 6 Portion is equipped with syringe needle 2, and the lower end base of the needle stand 6 is inserted with calparine cap 7, and the anti-needle thorn protective device front end 5 is inserted in again It is transfused in connector 4,4 front of infusion connector is equipped with hose 3, and the syringe needle 2 passes through anti-needle thorn protective device front end 5 and enters In hose 3, the syringe needle 2 protrudes from hose 3, is arranged with protective case 1 on the infusion connector 4.
The front inner wall of anti-needle thorn protective device front end 5 is equipped with several annular protrusions 12, outside the front end of the needle stand 6 Wall is equipped with several annular grooves 13, and described raised 12 match with groove 13, and the infusion connector 4 is equipped with corresponding retaining ring 11。
It is connected to inside the anti-needle thorn protective device middle section 8 and anti-needle thorn protective device end 9, it is whole in up-small and down-big The frustum of a cone.
Working principle: firstly, open protective case 1, remaining needle front end syringe needle 2 and hose 3 are pierced into together it is intravascular, to soft After pipe 3 fully enters blood vessel, infusion connector 4 is resisted with hand, infusion connector 4 and hose 3 are fixed on patient's arm, it is defeated at this time Note connector 4 falls off from anti-needle thorn protective device front end 5, and the connection of anti-needle thorn protective device front end 5 and needle stand 6 takes off automatically at this time It falls, 6 automatic retracted of needle stand pierces in protective device into anti-needle, when needle stand 6 is retracted into anti-needle thorn protective device end 9, due to liver There are gaps between plain cap 7 and the inner wall of anti-needle thorn protective device end 9, and ball 10 enters gap clamping calparine cap 7, so that institute It states needle stand 6 to be fixed in anti-needle thorn protective device, avoids the exposed of syringe needle 2 on needle stand 6, it is therefore prevented that medical staff is pierced by syringe needle Wound substantially increases safety, and syringe needle 2 is retracted in anti-needle thorn protective device, is had no any other operation, need to only be extracted infusion Connector 4,6 Automatic-falling of needle stand is ingenious in design, easy to use.
