International Classification:

A61M 37/00
A61M 5/00

US Classification:

604 89, 604191

Abstract:

A separation assembly for initially keeping a first component separate from a second component includes a generally cylindrical body slidably supported within a container between the first and second components. The body includes a seal structure having an inner seal member that initially seals the first component from the second component. In response to a predetermined operating condition, the inner seal member allows the first component to flow through at least one flow path in the seal structure to mix with the second component. The body further includes a flow distributing member disposed adjacent the seal structure to evenly distribute the first component into the second component. The seal structure and the flow distributing member form a single unit.

International Classification:

A61M 6/32

US Classification:

604192, 604198

Abstract:

An auto-injector for dispensing a predetermined dose of medicament is disclosed. The auto-injector includes a needle cover operative to engage an injection site. The needle cover is configured to move from a retracted position prior to a medicament dispensing operation to an extended locked position after the medicament dispensing operation. Any residual activation force remaining after the medicament dispensing operation is contained within the auto-injector and is not directed to the needle cover, thus attenuating, if not eliminating, any kickback effect.

International Classification:

A61M 5/32

US Classification:

604195

Abstract:

An automatic injector dispenses a predetermined dose of medicament without a user having to manually force the needle into an injection site. The automatic injector includes a needle cover having a locked retracted position with respect to the injector housing prior to a medicament dispensing operation. The needle cover is operative to engage an injection site prior to a medicament dispensing operation.

International Classification:

A61M 500

US Classification:

604232

Abstract:

An injection device includes a generally tubular outer body and a medicament cartridge assembly carried within the outer body. The cartridge assembly includes a glass container, a charge of medicament disposed within the glass container, iii) a plunger member rearwardly confining the medicament, and iv) a seal for sealing the forward portion of the glass container. A needle has a rearward end disposed proximate the seal, with the seal and needle being movable with respect to one another. A rigid needle cover member is normally maintained in an inoperative position and is movable relative to said body to a protective position wherein the needle cover member extends forwardly to cover the forward end of the needle. A releasable spring is releasable in response to a predetermined actuating procedure to drive a collet member forwardly within the outer body and thereby enable i) the cartridge assembly to move relative to the needle so that the rearward end of the needle pierces the seal to establish communication with the medicament, ii) the needle to move with respect to the body so that the needle projects outwardly from the forward end of the body, and iii) the needle cover to move relative to the body from the inoperative position to the protective position so that the needle cover member extends beyond the forward end of the needle.
