Injection systems
First Claim
1. An injection system comprising:
- an injector device having a first cavity in fluid communication with an orifice, the orifice configured for needle-less injection such that a fluid contained in the first cavity can be ejected through the orifice into an injection site; and
a fluid transfer device having a second cavity containing fluid, a proximal end coupled with the injector device proximate the orifice, a first seal and a moveable fluid passageway, the moveable fluid passageway being positioned between the first cavity and the first seal in an initial position, the fluid passageway configured to pierce the first seal in a transfer position thereby fluidly coupling the second cavity with the first cavity, the fluid transfer device being removeable from the injector device upon transfer of the fluid from the second cavity to the first cavity.

Abstract
The invention in general relates to various injection systems and devices that can be used, for example, in needleless injection systems for human, and for domestic and farm animals. In certain embodiments, the invention provides an injection system comprising: an injector defining a first cavity in fluid communication with an orifice configured for needleless injection; a housing defining a second cavity, the housing different than the injector; a first movable member between the first cavity and the second cavity, wherein the first movable member is configured to transfer a fluid from the second cavity to the first cavity; and wherein the first movable member is configured to be substantially stationary until the first movable member is moved by a propellant.
