Title: Self-inflating liquid container for keeping I.V. fluid or blood plasma

Abstract: A self-inflating liquid container that includes an inner flexible plastic receptacle for the retention of a liquid such as blood or the like, with a drain tube connected to the lower end of the inner receptacle, so as to permit the outward flow of the liquid from the inner receptacle. Supporting means is connected to the upper end of the inner receptacle so as to permit the liquid contained therein to exit through the drain tube. An outer flexible plastic receptacle substantially surrounds and encloses the inner flexible receptacle so as to form a chamber therebetween, with a first unidirectional valve on the outer receptacle for permitting the inward flow of gas into the chamber such that the outer receptacle can be inflated, so as to obtain a force applied to the inner receptacle to aid in the outward flow of the liquid from the inner receptacle through the drain tube.
