ABSTRACT:
This invention relates to a "plungerless" means of drawing blood and for administering liquids via parenteral injection. This means is used in conjunction with a pouch bearing an injection means, to which it is releasably attached. It comprises hinged plates which, when folded, expand the pouch; and which, when straightened, compress it.
In a preferred embodiment, the plates fold along a line essentially parallel to the general direction of fluid flow, and extend beyond the distal end of the pouch. The expanded pouch may then be rested on the distal edges of the plates, which form a "diamond" configuration.
