Embodiment

[0043] Embodiment: a kind of novel syringe, its structure is as Figure 3-8 shown, including:

[0044] Needle cap 5, needle head 6, barrel 7 and piston 8;

[0045] The needle cap 5 includes a cap body 521, the cap body 521 is a hollow cylindrical structure, the top of the cap body 521 is a closed structure, and the bottom is an open structure;

[0046] The side of the cap body 521 has a first through groove 527;

[0047] The inner wall of the cap body 521 is fixedly connected with the sleeve 524 through four connecting plates 525;

[0048] The top of the sleeve 524 is a closed structure, and the bottom is an open structure;

[0049] The side of the sleeve 524 has a second through groove 528;

[0050] The first through-slot 527 and the second through-slot 528 together become a passage for the piercing part of the needle 6 to enter the inside of the cap body 521 .

[0051] An arc-shaped baffle 523 for closing the first through groove 527 is arranged between the sleeve 524 a...

Abstract

The invention relates to a novel injection syringe, and belongs to the related technical field of medical apparatuses and instruments. The novel injection syringe mainly comprises a syringe cap, a syringe needle, a cylinder body and a piston. The syringe cap comprises a cap body, the cap body is of a hollow cylinder structure, the top part of the cap body is of a closed structure, and the bottom part of the cap body is of an open structure; a first through groove is formed in the side part of the cap body; the inner wall of the cap body is fixedly connected with a cannula through a connecting plate; the top part of the cannula is of a closed structure, and the bottom part of the cannula is of an open structure; a second through groove is formed in the side part of the cannula; an arc baffle plate used for closing the first through groove is arranged between the cannula and the cap body, one side of the arc baffle plate is fixedly connected with a direct baffle plate, the other side of the arc baffle plate 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; and the direct baffle plate protrudes out of the cap body. By designing the novel structure, a medical worker is prevented from being stabbed in the looping process, and the risk that a puncturing part scrapes a plastic particle on the syringe cap is also avoided.

Description

technical field [0001] The present invention relates to the relevant technical field of medical equipment, in particular, relates to a novel syringe. Background technique [0002] Syringes are one of the common medical devices. refer to figure 1 As shown, the syringe generally includes a needle cap 1 , a needle head 2 , a cylinder body 3 and a piston 4 , and the needle cap 1 and the needle head 2 are buckled together. [0003] refer to figure 2 As shown, the existing needle head includes, from top to bottom, the piercing part 211 , the connecting part 212 , the diameter-reducing part 213 , the equal-diameter part 214 and the convex part 215 . Among them, the puncture part 211 is airtightly connected with the reducing part 213 through the connecting part 212, the reducing part 213 is convenient for the fastening of the needle cap 1, the equal diameter part 214 is used for limiting the position during the fastening process of the needle cap, and the convex part 215 is conv...
