Patent ID: 8366658

Claim:
A closed IV solution delivery system for intravenous delivery of a hazardous solution, the system comprising: a coupling assembly having an input and an output, the input configured for coupling to a primary fluid reservoir to provide flow of a fluid from the primary fluid reservoir to the output; a drip chamber having an input and an output, the input of the drip chamber coupled directly to the output of the coupling assembly to receive fluid from the flow of the fluid from the primary fluid reservoir to form a secondary fluid reservoir within the drip chamber, the output of the drip chamber being configured to receive a patient conduit, wherein coupling between the input of the coupling assembly and the primary fluid reservoir prevents venting between the drip chamber and an external environment; a priming port in direct fluid communication with the drip chamber, the priming port having a self-sealing valve thereby preventing venting between the drip chamber and the external environment; and a membrane disposed within the drip chamber and interposedly positioned between the secondary fluid reservoir and the output of the drip chamber, wherein once wetted, the membrane prevents passage of air from the drip chamber to the output of the drip chamber, thereby preventing venting between the drip chamber and the external environment.
