Specific embodiment

Embodiment 1：

A kind of anti-pricking wound type remaining needle, a kind of anti-pricking wound type remaining needle, it includes casing seat 3, safe chuck 4, bullet Piece 5, catch 6, needle tubing 7, needle stand 8；There is in described sleeve pipe seat cavity, be provided with safe chuck 4 in described cavity；Described safety Transversely axis has the through hole running through safe chuck to chuck 4, is provided with shell fragment 5 and catch 6 in described safe chuck；Described shell fragment 5 have tilt push front segment structure, the middle section structure parallel to axis of pitch, with bulge-structure and longitudinally perpendicular in axis Locating slot rear section structure；Described catch 6 central authorities have one only can hold the through hole that needle tubing passes through；Described needle tubing 7 anterior for syringe needle, Middle part has bulge-structure, and described needle tubing 7 stretches in safe chuck 4 and passes through the locating slot of shell fragment 5 and the through hole of catch 6, institute The bulge-structure stating needle tubing 7 before the through hole of catch 6, be fixed on needle stand 8 by the rear portion of described needle tubing 7；Described safe chuck 4 Inside it is provided with one high and one low two projection, the projection of described shell fragment 5 back segment is stuck in above the high projection of described safe chuck 4, Described shell fragment 5 is pressed in above the low projection of described safe chuck parallel to the middle section structure of axis of pitch；Described anti-needle-penetrating stays Put pin and also include sheath 1 and sleeve pipe 2, described sleeve pipe is connected to casing seat front end and is communicated with the cavity of described sleeve pipe seat, described Sheath is placed on outside sleeve pipe；The diameter of the bulge-structure in the middle part of described needle tubing or width are more than the diameter of described catch through hole；Described Safe chuck, shell fragment, catch, needle tubing, needle stand are overall structures；Described sleeve pipe seat, safe chuck, sheath and sleeve pipe are each only Vertical.

During use, pull away casing seat 3 process in needle tubing 7, after needle point exits shell fragment 5 front end, shell fragment resilience pushes, shell fragment Tilt the front segment structure pushing and stop that needle point moves toward casing seat 3 direction again, the catch 6 when needle tubing 7 lobe falls back on catch 6 Through hole can block the boss of needle tubing 7, thus making needle tubing 7 can not exit safe chuck, last needle tubing 7 is with safe chuck 4 disengaging casing seats 3, safe chuck 4, shell fragment 5, catch 6 three's collective effect are thus make whole section of needle point be collected in safe chuck 4 Interior, realize needle point protection effect, it is to avoid occur needle point hurt sb.'s feelings, the phenomenon of cross infection.

Above-described embodiment simply to illustrate that technology design of the present utility model and feature, its objective is to be to allow this area Interior those of ordinary skill will appreciate that content of the present utility model and implements according to this, can not be limited of the present utility model with this Protection domain.Equivalent change done by every essence according to this utility model content or modification, all should cover in this reality With in new protection domain.
