Title: PRIMING DEVICE FOR MEDICAL INFUSION SYSTEMS
Abstract:
A priming device for a medical infusion system is provided, for enabling a fluid delivery tubing operatively connected to a liquid source to be automatically primed with liquid from the source during operation of the device. The device has a fluid inlet in fluid communication with a bypass outlet via a chamber. The fluid inlet is adapted for operative connection with the delivery tubing, and the bypass outlet has suitable air venting means for air venting at least gas away from the chamber during operation of said device. A suitable valve is provided, the valve being adapted for enabling liquid communication between the chamber and a valve outlet to be selectively prevented or allowed during operation of said device, according to predetermined conditions. Suitable connectors at the valve outlet enable connection of the device to a patient interface end such as a cannula. Medical infusion systems, such as intravenous infusion administration sets, or dialysis or bypass blood systems, incorporating such a device are also provided.
