Abstract

The invention relates to the technical field of an injection needle and specifically relates to an injection needle with a syringe needle protective sleeve. The injection needle comprises a syringe (1) whose top end is provided with a syringe needle (2); and a protective sleeve (3) which is arranged at the top end of the syringe (1), wherein the protective sleeve comprises an inner sleeve (31) fixedly connected with the syringe (1) and an outer sleeve (32) which sleeves the outer side of the inner sleeve (31) and can perform reciprocating movement along the outer wall of the inner sleeve (31), the outer sleeve (32) is provided with a collection position and a protection position, the outer sleeve (32), when being at the protection position, internally forms an accommodation chamber (4) used for protecting the syringe needle (2); and the inner wall of the outer sleeve (32) and the outer wall of the inner sleeve (31) are provided with a locking structure for locking the two at the protection position. The injection needle with the syringe needle protective sleeve, provided by the invention, can effectively prevent the syringe needle of the injection needle from contamination, facilities reuse, and at the same time, reduces safety hidden trouble that the syringe needle pricks skin.

Description

technical field [0001] The invention relates to the technical field of injection needles, in particular to an injection needle with a needle protective cover. Background technique [0002] The injection needle generally includes a cylinder body, a needle holder installed on the top of the cylinder body and a needle fixed in the needle holder, and a needle protection cover is sheathed on the needle head. When in use, remove the needle protection cover for injection. After the injection, in order to avoid the needle from stabbing the skin of others, generally the needle protection cover is directly re-covered on the needle, so that there is still the possibility of stabbing the operator’s skin during this operation. Possibility, there are certain security risks. For example, the Chinese patent document CN104771814A discloses a disposable safe insulin injection needle, which includes a needle body, a needle seat, a main housing, and an outer sheath. The outer sheath is used to...
