ABSTRACT:
A compact, integrated intravenous fluid delivery device. The invention may be used between an intravenous fluid source and an intravenous fluid line. In this embodiment, the invention includes a housing, through which a fluid passageway is disposed. The fluid passageway passes through a spike, which is used for connecting the housing to the fluid source. The passageway also passes through a rigid drip chamber and a priming element that may be repeatedly compressed in order to urge fluid from the source into the drip chamber and through the intravenous fluid line. The priming element includes a rigid base portion and a membrane. The spike, drip chamber and the base of the priming element all form an integral piece of rigid material. This embodiment may further include a valve chamber disposed in the housing, such that the fluid passageway enters and exits the chamber through two mouths. A valve membrane is attached to the housing and covers the valve chamber, so that the membrane may be urged to cover at least one of the two mouths.
