| 摘要 |
A post-injection sheath for a hypodermic syringe needle includes an accordion-shaped resilient sheath body, which is fixedly secured to the needle hub at its one end and is movable from a compressed position, corresponding to a ready-to be used position of the needle, to an expanded position, in which the sheath body covers the needle. The sheath body supports, at its second open end, an end cover which is adapted to pivot from a first position, in which it extends parallel to the longitudinal axis of the sheath body, to a second position, in which it extends transverse to the longitudinal axis of the sheath body and covers the open end of the sheath body. The end cover pivots from its first position to its second position when the sheath body reaches its expanded position. The end cover is provided with a hub portion having a chamber into which the needle tip projects and in which it is deformed.
