Combined Medical Device with Sliding Frontal Attachment and Retractable Needle

Abstract

A medical device is disclosed as having a body comprising an open-ended fluid flow chamber and a laterally offset needle retraction chamber. A frontal attachment that includes a forwardly projecting needle support is slidably coupled to the body. A retractable needle assembly comprising a needle holder, a retraction spring rearwardly biasing the needle holder against the forwardly projecting needle support, and a needle extending forwardly from the forwardly projecting needle support is carried by the frontal attachment, which is laterally slidable with respect to the body from a first position in which the needle is aligned and in fluid communication with the open-ended fluid flow chamber to a second position in which the needle is aligned with the needle retraction chamber to initiate retraction of the needle holder and the needle into the needle retraction chamber.
