Abstract

The invention relates to an anti-puncture blood drawing needle, which belongs to the technical field of medical instruments; the anti-puncture blood drawing needle comprises a blood supply needle and a protective sleeve for wrapping and protecting the blood supply needle, and is characterized in that the protective sleeve is an anti-puncture section in a blood supply needle tip area; the distance from the far end of the anti-puncture section to the blood supply needle tip is 2-5mm; and the far end part of the anti-puncture section is a puncture end. By arranging the protective sleeve with the anti-puncture section, the blood supply needle can be prevented from puncturing out of the side face of the protective sleeve in the puncture operation; and harm to medical staff is avoided. Meanwhile, the safe distance is set through theoretical calculation and repeated tests; namely, the distance from the far end of the anti-puncture section to the blood supply needle tip is 2-5 mm which is the most reliable distance; and puncture can be prevented.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a stab-proof blood-drawing needle. Background technique [0002] The connected specimen end of the existing blood-drawing needle, that is, the end of the blood supply needle, is usually wrapped with a soft rubber sleeve. On the one hand, the soft rubber sleeve is easy to be pierced and compressed, so that the blood supply needle is connected with the test tube, and blood is introduced into the test tube through negative pressure. The soft rubber sleeve can restore the wrapping protection of the blood supply needle after being punctured, prevent it from being contaminated by the external environment, and facilitate the provision of clean blood samples to ensure the accuracy of the test. [0003] However, the existing soft rubber sleeve also has certain problems: because the soft rubber sleeve has the same material, the blood supply needle can be pierced from any position o...
