Safe needle guard for butterfly needle group

Abstract

The invention discloses a safe needle guard for a butterfly needle group. The safe needle guard for the butterfly needle group is used for sheathing one butterfly needle group, and in addition, the butterfly needle group is connected with a transfusion adapter tube. The safe needle guard comprises a connection block, wherein the connection block is provided with a through hole through which the transfusion adapter tube connected with the butterfly needle group can pass; two sides of the through hole of the connection block respectively outwards extend to form a first clamping piece and a second clamping piece; the connection block, the first clamping piece and the second clamping piece are integrally formed; the first clamping piece outwards extends on the tail end to form a first warping end part; two sides of the bottom surface of the first clamping piece are respectively provided with a notch groove; the second clamping piece and the first clamping piece are jointly and correspondingly connected to the connection block; the tail end of the second clamping piece corresponds to the first warping part to extend to the other side to form a second warping part; an open elastic needle guard opening is formed between the two warping parts on the tail end of the safe needle guard; the positions on the second clamping piece, which correspond to the notch grooves, are respectively provided with a stop valve; and a guideway which is separated into a front section and a rear section by a stop valve area is formed between the two clamping pieces.

Description

technical field [0001] The invention relates to a safety needle cover, in particular to a butterfly needle group safety needle cover used in conjunction with a butterfly needle group. Background technique [0002] Currently, there are many structures designed for medical butterfly needles. For example, Taiwan Patent Publication No. 221556 "Innovative Structure of Butterfly Needle Safety Needle Cover" is an example; the feature of this patent is mainly a hollow cylinder. There is a slot on the needle cover, the front end of the slot is a "V"-shaped and slightly arc-shaped inlet, one or one thin straight slot is opened in the middle section, and a slender rectangular slot is opened at the end The clamping groove, the front end of the clamping groove is provided with two inclined guide angles, the butterfly needle is inserted into the safety needle cover, and the wings of the butterfly needle are braced and fixed in the clamping groove of the safety needle cover.

Problems solved by technology

[0003] However, this "innovative structure of the butterfly needle safety needle cover" directly forms a "V"-shaped opening at the front end of the needle cover, so that the thin slot is too wide, and its clamping The front end of the groove is designed with two inclined guide angles. Therefore, once the butterfly needle is pushed or shaken by external force, it is easy to make the wings of the butterfly needle slide out of the thin groove through the guide of the inclined guide angle of the clamping groove. The needle protrudes out of the needle cover, causing people to be injured by the needle and infected with the virus.
