A compact, integrated intravenous fluid delivery device. The invention may be used with an intravenous fluid source and an intravenous fluid line. In this embodiment, the invention includes a housing (60), through which a fluid passageway (602) is disposed. The fluid passageway passes through a spike (601), which is used for connecting the rigid housing to the intravenous fluid source. The passageway also passes through a rigid drip chamber (63), and a priming element (64) that may be repeatedly compressed to urge fluid from the intravenous fluid source into the drip chamber (63) and through the intravenous fluid line. The priming element (64) includes a base (642) and a priming membrane (641). The intravenous fluid line is mounted on the housing (60), such that the fluid passageway leads into the intravenous fluid line. The spike (601), the drip chamber (63), the base of the priming element (64) and the receiving means all form an integral piece of rigid material. This embodiment may further include a valve chamber (611) disposed in the housing, such that the fluid passageway leads into and out of the valve chamber through first and second mouths, with a valve membrane attached to the housing and disposed over the valve chamber so that the valve membrane may be urged to cover at least one of said first and second mouths. |
