Peristaltic infusion device with backpack sensor

摘要

The present invention relates to a sensed member and sensing member for use on a medical fluid infusion device and support device wherein the fluid infusion device is usable in a conventional manner such as on an IV pole and in an ambulatory manner such as in a support device for use in an ambulatory backpack. The sensing member of the present invention detects when the fluid infusion device is to be used in an ambulatory manner to adjust the operation of the infusion control member to account for the difference in fluid flow rates caused by the different fluid pressures within the fluid delivery set when the fluid infusion device is used in a conventional manner and an ambulatory manner.
