Syringe needle and syringe

Abstract

The invention provides a syringe needle and a syringe. The syringe needle comprises a needle body and a needle base, and the needle body is connected with the needle base. The syringe needle further comprises a protective sleeve which is movably connected to the needle base through a connecting unit and arranged on the inner side of the needle base. When the protective sleeve stays in a retractedstate, the distance between the end, close to a needle point, of the protective sleeve and the needle base is smaller than the distance between the needle point and the needle base; when the protective sleeve stays in an open state, the distance between the end, away from the needle base, of the protective sleeve and the needle base is greater than the distance between the needle point of the needle body and the needle base;. That is to say, through arrangement of the protective sleeve on the needle base, when the protective sleeve stays in the open state, the whole needle body is positioned in the protective sleeve, so that the problem is avoided that the hands touch the needle body by accident and are thus pricked when medical workers or patients take off the syringe needle or under other conditions when the syringe needle is touched. At the same time, this form of protective sleeve only needs to be opened when it is needed. Compared with the prior art, the syringe needle has the advantages that the operation process is more convenient and fast, and correspondingly the user experience is better.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a syringe needle and a syringe. Background technique [0002] Syringes are common medical devices in the medical field. Current syringes mainly come in two forms: disposable syringes and injection pens. In order to avoid virus cross-infection caused by repeated use of syringes, current syringes or syringe needles are recommended for single use. When patients or medical staff use disposable syringes for injection, they remove the needle cap on the syringe needle for injection, cover the needle cap and throw it away after injection; when using an injection pen, it is necessary to install the needle matching the syringe on the syringe For injection, remove the needle directly after the injection or manually put a protective cover on the needle body and remove the needle. In the process of using the syringe, the process of pulling out and installing the needle cap, installing and rem...
