Abstract
A feeding device for the enteral introduction of nourishment to a human patient which device is comprised of three sheets of inextensible material sealed together to form four independent compartments. The top two compartments which are larger form a reservoir for the feeding solution and a container for coolant in order to preserve the feeding solution over extended periods of time. A tube leading from the reservoir travels through a four way valve wherein the solution is directed to either of two feeding chambers which have a common dividing wall formed by the dividing sheet of material. The dividing wall is flaccid so as to be able to contact and conform to either of the outer sheets. The four way valve serves to alternate the flow of solution from the reservoir to one of the chambers while opening the flow from the other chamber to the patient. A simple clamping means allows for the determination of the amount of solution which can be introduced into the feeding chambers thereby determining the volume of the bolus of nourishment being provided to the patient.
