Problems solved by technology

Therefore, as long as the nursing staff is a little careless, the hand holding the needle cover may be injured by the sharp point of the needle, or even infected by the virus; A sleeve with a longitudinal chute is required to retract the needle of the used butterfly injection needle into the sleeve, which is not only time-consuming and costly, but also the needle of the used butterfly injection needle can be deliberately retracted into the sleeve again. out of the sleeve, making the sleeve useless and unable to ensure its absolute safety in use
[0003] Furthermore, due to the small size of the traditional butterfly injection needle, and the butterfly wings and the support tubes behind the injection needle are all made of flexible plastic material, when people add safety measures to the protective sleeve, it is difficult to save space. And the structure is subject to considerable restrictions, so it has insurmountable problems in the safety and practicability of its use, which has been unable to be solved for a long time

Abstract

A high-safety sleeve device for butterfly needle is composed of a cover unit, a high-safety needle sleeve unit and a needle holder unit. Said needle sleeve unit is a hollow tubular body with butterfly wing part and T-shaped slide slot. Said needle holder unit with needle is a hollow tubular body with front boss, a backened for connecting traditional injector, and a step part for fixing needle unit. After the needle has has been used, the needle holder unit can be withdrawn back into needle sleeve unit.

Description

1. Technical field [0001] The invention provides a butterfly needle safety needle cover device, especially a butterfly needle safety needle cover device which can prevent medical personnel or other people from being stabbed by the contaminated butterfly needle needle after use. 2. Background technology [0002] Generally, the traditional butterfly needle is used, as shown in Figure 10, the protective needle cover (C) at the front end of the butterfly needle is removed, the needle (N) is inserted into the human body for injection, and the butterfly wing (B) is attached to the human body (not shown in the figure) pull out the needle (N) after the injection is completed. Since the needle (N) has been contaminated, the needle (N) must be carefully put back into the original protective needle cover (C). It is used for the injection of drip bottles, and the injection time is as long as several hours. During the period, the needle may be displaced, the needle may slip out of the bl...
