Description

A kind of safety cap for syringe needle

[technical field]

The utility model relates to a kind of safety cap, specifically the utility model and relates to a kind of peace for syringe needle Full cap.

[background technology]

Known, treat one of disease most common method during intramuscular injection, the syringe used clinically is by pacifying Full cap, needle tubing, syringe needle, piston and piston push rod composition, before having injected, nurse generally in nurse station by required medicine injection In suction needle tubing, being screwed on syringe needle with anti-pollution with safety cap, nurse enters back into ward and sufferer is carried out intramuscular injection, has injected Safety cap is screwed on syringe needle by Bi Yihou again, in case unnecessary stabs, aforesaid operations process is complex, due to safety cap and Syringe needle be two bodies combination arrange, safety cap easily drops or loses, it is therefore proposed that a kind of safety in utilization higher be used for inject The safety cap of device syringe needle becomes the basic demand of those skilled in the art.

[summary of the invention]

In order to overcome the deficiency in background technology, the utility model discloses a kind of safety cap for syringe needle, By arranging the sleeve pipe being slidably matched in the bar blocks of needle tubing periphery, it is achieved that syringe needle does not leaks outside, and use simple operations Purpose easily.

For achieving the above object, the utility model adopts the following technical scheme that

A kind of safety cap for syringe needle, including needle tubing, the syringe needle of needle tubing upper end and the annular table of needle tubing lower end, Being provided with bar blocks from top to bottom on the periphery of needle tubing, be provided with sleeve pipe in the outside of needle tubing, described sleeve pipe is provided with and bar shaped Block coordinates the groove slided, and is provided with hollow frustum on the top of sleeve pipe, and the upper side at frustum is provided with through hole.

The described safety cap for syringe needle, is respectively equipped with upper stop piece, lower gear plate on the top and bottom of bar blocks, All it is connected by rotating shaft is fixing between described upper stop piece, lower gear plate and bar blocks.

The described safety cap for syringe needle, is respectively equipped with on a side of groove or on dual-side and opens Mouth, under shed.

Owing to have employed technique scheme, the utility model has a following superiority:

Safety cap for syringe needle described in the utility model, by arranging bar blocks on the periphery of needle tubing With upper stop piece, lower gear plate, being provided with the sleeve pipe of groove in the outside of needle tubing, upper stop piece, lower gear plate pass through axis of rotation, respectively It is arranged in the upper shed of groove one side, under shed, simple and convenient when operation, it is to avoid syringe needle leaks outside and stabs medical personnel Or the drawback of sufferer, and in use, due to fixing of sleeve pipe, it is therefore prevented that the downslide of sleeve pipe when medical personnel have an acupuncture treatment.
