Abstract
A pump for delivering a liquid from a container to a patient through a flow set. The pump includes a sensing means and a controller. The sensing means senses a parameter indicative of the pressure in the flow set. The controller has a computing and memory means for determining deviation of the parameter from a standard. Deviation is indicative of an error in the flow set. This enables supervising staff to be alerted. These errors may be incorrect assembly of the system or one of its components, inclusion in the system of an incorrect valve, impairment in the integrity of the flow set, and the existence of air bubbles in the system.
