Abstract

A disposable safety butterfly needle structure comprises a protecting sheath member, a slide member, and a flexible tube. The protecting sheath member is provided with a slide slot, Convex buttons are provided respectively near to the front end, back end and slightly foreside of the back end of the slide slot. A deflected angle is formed behind the convex buttons of the back end, and an annular blocking portion is provided on the front end of the protecting sheath member through which only the needle can pass. The upper edge of the slide member is connected with a pushing portion by a slide block, and the slide member is in the protecting sheath member and fixed between the convex buttons provided on the back end and slightly foreside of the back end of the slide slot. When the slide member is pushed backward by the pushing portion, it is affected by the deflected angle such that the tip of the needle is inclined and blocked by the annular blocking portion, and the needle can't pass through the protecting sheath member for further use.

Description

technical field [0001] The invention relates to a single-use safety butterfly needle structure, in particular to a one-time use safety butterfly needle structure which is safe, easy to operate and does not need to worry about being used for secondary use.
