Claim Text:
1. A method for verifying that a particular fluid supply is connected to a pump mechanism wherein the pump mechanism acts on a fluid line coupled to the fluid supply to control movement of fluid from the fluid supply through the fluid line, the method comprising: causing an operator-induced pressure change in the fluid line at a downstream portion of the fluid line located between the pump mechanism and a patient, wherein a collapsible reservoir is positioned entirely external of the pump mechanism and located in the downstream portion of the fluid line entirely downstream of the pump mechanism, and wherein causing the operator-induced pressure change comprises squeezing the reservoir, wherein the reservoir includes a one-way valve that inhibits fluid flow toward the patient when a pressure change occurs in the reservoir; sensing pressure in the downstream portion of the fluid line; detecting the operator-induced pressure change in the downstream portion of the fluid line and indicating a connection verification that the fluid supply is connected to the pump mechanism upon detection of the operator-induced pressure change.
