Abstract

The invention relates to a needle cap suitable for a syringe and belongs to the technical field of medical instruments. The needle cap mainly includes a hollow cylindrical cap body, the top of the cap body is of a closed structure, and the bottom of the cap body is of an open structure; the side portion of the cap body is provided with a through groove, the inner wall of the cap body is fixedly connected with a sleeve pipe through a connecting plate, the top of the sleeve pipe is of a closed structure, and the bottom of the sleeve pipe is of an open structure; the side portion of the sleeve pipe is provided with a second through groove, an arc-shaped baffle used for sealing the first through groove is arranged between the sleeve pipe and the cap body, and one side of the arc-shaped baffle is fixedly connected with a straight baffle; the other side of the arc-shaped baffle is fixedly connected with one end of an elastic part, and the other end of the elastic part is fixedly connected with the connecting plate; the straight baffle protrudes out of the cap body. By designing a novel structure, the situation that medical-care personnel is stabbed in the sleeving process can be avoided, and the risk that a puncture part scratches plastic particles on the needle cap can be avoided.

Description

technical field [0001] The invention relates to the relevant technical field of medical equipment, in particular to a needle cap suitable for a syringe. Background technique [0002] Syringes are one of the common medical devices. It generally includes a needle cap, a needle head, a cylinder body and a piston, and the needle cap and the needle head are snapped together. [0003] refer to figure 1 As shown, the existing needle head includes the puncture part 11 , the connecting part 12 , the diameter reducing part 13 , the equal diameter part 14 and the convex part 15 from top to bottom. Among them, the puncture part 11 is airtightly connected with the variable diameter part 13 through the connecting part 12, the variable diameter part 13 is convenient for the fastening of the needle cap, the equal diameter part 14 is used to limit the position during the fastening process of the needle cap, and the convex part 15 is convenient for the needle from Remove from cylinder. ...
