Abstract

A transcutaneous injector having an integral sealing means for cooperation with a protective cover to facilitate aseptic storage of biological substances. The cup-shaped cover is provided with vent ports for accomplishing a vacuum before the injector is fully positioned within the cover interior. A resilient flange annularly attached to the injector selectively effects a seal with the cover or allows communication of the vent ports to the interior of the cover.

Claims

1. A transcutaneous injector package having a holder, a metal plate and a cover, said holder being thimble shaped and including a substantially rigid end, said end having means cooperating with and mounting said metal plate thereon, an upstanding sidewall having gripping means to permit said sidewall to act as a handle, said metal plate including a plurality of needlelike protuberances extending in a single direction away from said plate and means on said plate for cooperation with said end to mount said plate, said cover being hollow and cup shaped with one open and one closed end with a substantially continuous inner wall, means on said holder cooperating with means on said cover to limit the entry of said holder into said cover, integral sealing means on said holder including an inverted continuous umbrellalike resilient flange extending axially and outwardly along said handle away from said plate, said inner wall having a predetermined diametral measurement, said flange having a substantial axial extent with diametral measurements less than said predetermined measurement at its juncture with said handle and greater than said predetermined measurement at its free end so that a substantial portion of said flange is deflected radially inwardly and engages the inner wall of said cover, said flange being adapted to more aggressively engage said inner wall of said cover when the interior of said cover is evacuated and a differential in pressure exists between ambient conditions and the interior of said cover.

2. An injector of the type claimed in claim 1 wherein said cover includes vent port means To aid in evacuation of said cover but which are inoperative when said holder is seated relative to said cover.

3. An injector of the type claimed in claim 1 wherein said flange is generally frustoconical in configuration which terminates in an axially extending annular portion having an external diametral measurement greater than said predetermined measurement.
