ABSTRACT:
An expandable syringe comprising an elastic bag having an opening through which liquid may pass and a nozzle having a tubular body defining a central passageway and a tip on an end thereof. The nozzle is provided with at least one peripheral port in fluid communication with the tubular body central passageway. A mount is also provided for detachably mounting the nozzle to the elastic bag with the tubular body central passageway in valve controllable fluid communication with the elastic bag opening.
Means for storing and readily obtaining access to a set of individually proportional and encapsulated chemical agents for successive use with an expandable syringe comprising a case and a unitary slit jacket sized to hold juxtaposed envelopes encapsulating the agents and sized to be slidably received within the case. The jacket has a pair of juxtaposed tabs adapted to be manually gripped in sliding the jacket into and out of the case.
A convertible valve is also disclosed for introducing liquid into a bag from a spout and for expelling liquid from the bag through a syringe nozzle. The convertible valve comprises a tubular valve seat having a radially inward directed flange having an aperture therethrough intermediate the ends thereof. A device is included for securing the valve seat to the bag in fluid communication with an opening in the bag. A bulbous gasket is provided having a tubular section mounted within the valve seat upon the side of the valve seat flange distal the bag, a neck section extending through the valve seat flange aperture, and a flange section mounted upon the valve seat flange proximal the bag. The convertible valve also includes a flexible disc mounted within the valve seat in abutment with the gasket flange portion and having a flap movable between positions closing and opening the end of the gasket neck section proximal the bag.
