Abstract
The invention provides a safe needle, comprising a needle body and a protecting jacket with which the needle body is sheathed. The needle body is connected with a conduit by a joint which is composed of a needle pin and a needle table and shaped like a footstep with a small upper part and a big lower part; the protecting jacket comprises a needle cap and a sleeve which is embedded in the needle cap and an upper round hole and a lower round hole are arranged at the centers of the upper end surface and the lower end surface of the needle cap respectively; the top end of the n-shaped sleeve is clamped outside the upper round hole of the needle cap; a least one clamping strip which extends sideward and downwards is arranged at the inner wall of the needle cap. The protecting device and the needle body are integrated, thus the operation is convenient and no other equipment is necessary for processing the needle body. The needle body can be well protected before or after the needle is used, medical staff is prevented from being punctured and secondary hurt to recovering staff is avoided.
Description
Technical field
The invention belongs to the medical apparatus technical field, be specifically related to the syringe needle that a kind of safe being used to infused, transfused blood.
Background technology
The syringe needle that is used to infuse, transfuse blood is with a cylindric pin medicated cap before use, during use, extracts and just throws into garbage can behind the pin medicated cap conveniently.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, careless slightlyly in the process of medical worker with pinhead sleeve back stitching medicated cap still very easily stab oneself because the relative aperture of pin medicated cap is less; The pin cap sleeve is also insecure on syringe needle in addition, is prone to come off, and this also will possibly 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 present invention provides a kind of safety needle, comprises spike body and is sheathed on the protective sleeve on the spike body, and said spike body is connected with conduit through joint, said joint by pintle and pin platform form up-small and down-big step-like; Said protective sleeve is made up of pin medicated cap and embedded wherein sleeve, and the center of the upper and lower end face of said pin medicated cap offers upper and lower circular hole; Said sleeve is n shape, and its top is stuck in the last circular hole outside of said pin medicated cap; The inwall of said pin medicated cap is provided with at least one card article that extends to oblique below.
For ease sleeve is pulled up from the pin medicated cap, said telescopic top is provided with the leader.
Do not move for the pin medicated cap is fixed on the spike body place, said pin platform upper surface is provided with at least one fixture block that stretches to oblique upper.
The preferred version of such scheme is, the inwall of said pin medicated cap is provided with a circle card article, and said 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 to accidentally injure medical personnel with the pin medicated cap after spike body is used, said conduit and joint junction are provided with projection, and said 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 said handle is a lead-in wire.
The preferred version of such scheme is, said pin platform upper surface is provided with a circle fixture block, and said fixture block becomes bowl-shape around being centered around pintle, can be to connect in aggregates or be provided with 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 telescopic top is stuck in the last circular hole outside of pin medicated cap, is provided with a lead-in wire above it and is used to extract 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 through 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 to oblique upper.
Syringe needle covers spike body by sleeve before use, and telescopic lower end props up on the fixture block of being located at pin platform upper surface, also has frictional force between 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 in the other direction, can expose spike body and use; After using, the pin medicated cap is pulled back to the spike body direction, when moving to a certain degree, the card article on the pin medicated cap engages with the fixture block of pin platform upper surface again; 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 once more, avoid the spike body exposure and stab medical personnel, can't cause the secondary injury 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 all 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 once more, just can not cause the secondary injury the recovery personnel.
