Peristaltic infusion device with backpack sensor
First Claim
1. A medical fluid delivery system for the delivery of a medical fluid to a patient at a controlled rate;
- said system comprising;
a fluid delivery set including a reservoir means for containing fluid, a support structure for supporting said reservoir means, and a tube means forming a fluid flow pathway therethrough which is in fluid flow connection with said reservoir means;
a pump means for moving fluid through said fluid flow pathway and including a control means for adjustably controlling operation of said pump means; and
sensor means for determining the position of said pump means relative to said fluid delivery set, said sensor means including a sensing member and a sensed member, one of said sensing member and said sensed member being formed as part of said pump means and the other being formed as part of said support structure;
whereby, said control means adjusts operation of said pump means in accordance with the position of said pump means relative to said fluid delivery set as determined by said sensor means to ensure movement of fluid through said fluid flow pathway at said controlled rate.

Abstract
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.
