Abstract

A disposal injector capable of preventing an injector mix-up accident from occurring by filling chemicals therein beforehand and capable of being easily and safely disposed off by storing an injector needle after use in a piston so as not to be re-used, comprising an injector body having an injector needle mounting part formed at one end of a tubular body part and an opening part for accepting the piston formed at the other end, the injector needle mounted on the injection needle mounting part, and the piston inserted into the opening part, the tubular body part further comprising a means for restricting the movement of the piston formed by filling the chemicals therein beforehand and closing the chemicals by the piston, wherein the piston movement restriction means is formed by covering the piston rod of the piston with a bellows formed of the peripheral surface parts with flat surfaces of a specified width and bottom parts alternately continued with each other and a fixing sheet is adhered to the peripheral surface of the bellows.

Description

technical field [0001] The present invention relates to single-use syringes and, in particular, to assisting users in avoiding the mixing of one syringe prefilled with liquid medication with each other, and in assisting users in avoiding reusing a syringe with a used needle retained in a plunger single-use syringes for easy and safe disposal. Background technique [0002] Syringes currently used in the medical field are generally made of plastic such as croton resin, and most syringe bodies are made of glass. The syringe, along with its needle, is sterilized by boiling for reuse. Before use, the user draws the target liquid drug from the ampoule into the syringe each time. When inhaling liquid medicine, the user needs to check and remember the name of the liquid medicine. After filling the syringe with liquid drug, the user may be so busy that he confuses one name with another, or after a long time, the user may forget the name. Healthcare professionals must handle and a...
