Description

A kind of safety needle
Technical field
The invention belongs to the medical apparatus technical field, be specifically related to a kind of safe syringe needle that is used for transfusion, blood transfusion.
Background technology
The syringe needle that is used for transfusion, blood transfusion is with a cylindric pin medicated cap before use, during use, just throws into garbage can conveniently after extracting the pin medicated cap.Its syringe needle exposes after be totally lost, medical personnel pull out pin, so the situation that often has finger to be stabbed takes place, infects various blood-borne diseases easily.So hygiene department has strengthened the recycling management to waste and old medical apparatus.
At present, the recovery method of the syringe needle of disposable infusion, blood transfusion is generally had two kinds: a kind of is to utilize needle destroyer that syringe needle is ground destruction, but the needle destroyer volume is bigger, and inconvenience is carried, and inconvenient operation in addition is so popularization is not enough; Another kind is with pinhead sleeve back stitching medicated cap, throwing into recycling bin is transported to the medical waste recycle bin and concentrates destruction, but because the pin medicated cap is difficult for finding after taking off, in addition, even found, but because the relative aperture of pin medicated cap is less, careless slightlyly in the process of medical worker with pinhead sleeve back stitching medicated cap still very easily stab oneself; The pin cap sleeve is also insecure on syringe needle in addition, easily comes off, and this also will may cause the secondary injury to the recovery personnel.
Summary of the invention
The present invention will solve above-mentioned deficiency exactly, and the syringe needle that has protective sleeve of a kind of safety, handled easily is provided.
In order to reach above-mentioned effect, the invention provides a kind of safety needle, comprise spike body and be sheathed on protective sleeve on the spike body, described spike body is connected with conduit by joint, described joint by pintle and pin platform form up-small and down-big step-like; Described protective sleeve is made up of pin medicated cap and embedded wherein sleeve, and the center of the upper and lower end face of described pin medicated cap offers upper and lower circular hole; Described sleeve is n shape, and its top is stuck in the last circular hole outside of described pin medicated cap; The inwall of described pin medicated cap is provided with at least one card article that extends to oblique below.
For convenience sleeve is pulled up from the pin medicated cap, the top of described sleeve is provided with the leader.
Not mobile for the pin medicated cap is fixed on the spike body place, described pin platform upper surface is provided with the fixture block that at least one stretches obliquely upward.
The preferred version of such scheme is, the inwall of described pin medicated cap is provided with a circle card article, and described card article is positioned on the same horizontal plane.Card article can be to connect in aggregates or setting at interval.
In order to give the hands that entangles and prevent from accidentally injuring medical personnel with the pin medicated cap after spike body is used, described conduit and joint junction are provided with projection, and described projection is being blocked the following circular hole of pin medicated cap, make the pin medicated cap fix and do not glide.
The preferred version of such scheme is that described handle is a lead-in wire.
The preferred version of such scheme is, described pin platform upper surface is provided with a circle fixture block, and described fixture block becomes bowl-shape around being centered around pintle, can be to connect in aggregates or arrange at interval.
Protective sleeve of syringe needle integral body is cylindrical among the present invention, and sleeve is the n type and is embedded in the pin medicated cap, and the top of sleeve is stuck in the last circular hole outside of pin medicated cap, is provided with a lead-in wire above it and is used for extracting sleeve; Sleeve is just in time whole to being covered with spike body, prevents that spike body is contaminated before use; The bottom of pin medicated cap is located on the conduit by following circle hole sleeve.The inwall of pin medicated cap is provided with the card article that extends to oblique below, and pin platform upper surface is provided with the fixture block that stretches obliquely upward.
Syringe needle covers spike body by sleeve before use, and the lower end of sleeve props up on the fixture block of being located at pin platform upper surface, also has frictional force between the card article on the pin medicated cap inwall and the pin platform sidewall, makes protective sleeve be fixed on the top of spike body; Following circle hole sleeve on the pin medicated cap lower surface makes protective sleeve that spike body is fully protected on conduit.When using this product, the lead-in wire of firmly holding pin medicated cap upper end will be embedded in the interior sleeve of pin medicated cap and pull out, and will be again that the pin medicated cap is drop-down to opposite direction, can expose spike body and use; After using, again the pin medicated cap is pulled back to the spike body direction, when moving to a certain degree, card article on the pin medicated cap engages with the fixture block of pin platform upper surface, the following circular hole of this hour hands medicated cap props up the pin platform, and is stuck on the projection, and the pin medicated cap can be fixed, spike body is covered fully again, can not come off again, avoid the spike body exposure and stab medical personnel, can't cause the secondary injury to the recovery personnel.
In sum, the present invention has the following advantages:
1, protector and spike body are connected as a single entity, and be easy to operate;
2, the present invention is safe, spike body before use, after have protector that it is protected, reduced it and stabbed medical personnel's danger coefficient;
3, block after protector being pulled back after using, spike body is protected fully, and protective sleeve can not come off again, just can not cause the secondary injury to the recovery personnel.
