Abstract

Disclosed is a butterfly needle, which comprises a needle stand (12) and a needle cylinder (13) with a longitudinal axis, wherein the needle stand (12) is arranged in the needle cylinder (13) and can move to a retraction position from an extension position relative to the needle cylinder (13), the extension position being located at the distal side of the needle cylinder (13), and the retraction position being located at the proximal side of the needle cylinder (13). The butterfly needle further comprises an extension position locking device which can lock the needle stand (12) in the extension position in a releasable manner, and a retraction position locking device which can lock the needle stand (12) in the retraction position. After the use of the butterfly needle is completed, a needle head (11) thereof can be completely placed in the needle cylinder (13), thereby preventing the needle head (11) from causing an unexpected pricking wound.

Description

technical field [0001] The invention relates to a butterfly needle. Background technique [0002] In the medical practice of intravenous infusion, blood transfusion, blood collection, arterial and venous hemodialysis, etc., the intravenous infusion needles, venous blood transfusion needles, venous blood collection needles, arterial and venous hemodialysis needles traditionally called "butterfly needles" are usually configured On venous infusion sets, venous blood transfusion sets, venous vacuum blood collection sets, and arteriovenous lines for hemodialysis. The butterfly needle consists of a needle used to pierce into a blood vessel and a needle cap that covers the needle. On the one hand, the needle cap prevents the needle from being damaged, and on the other hand, it prevents the needle from accidentally stabbing medical staff and other personnel who may come into contact with the butterfly needle. [0003] In order to prevent the needles that have been used from causin...
