Abstract
Infusion systems including infusion devices and consumables and related operating methods are provided. An exemplary method of operating an infusion device operable to deliver a fluid influencing a physiological condition to a body of a user involves a control module of the infusion device obtaining calibration data associated with a consumable coupled to the infusion device via an interface of the infusion device, determining a delivery command for delivering the fluid to the body of the user based at least in part on the calibration data, and operating a pumping mechanism to deliver the fluid from a reservoir of the consumable to the body of the user in accordance with the delivery command.
Claims20
A system comprising:
- a consumable including a peristaltic pumping mechanism for dispensing a fluid and a readable element maintaining calibration data characterizing a relationship between delivery of the fluid and actuation of the peristaltic pumping mechanism;
- and
- an infusion device including an interface to obtain the calibration data from the readable element, an actuation arrangement configured to actuate the peristaltic pumping mechanism and a control module coupled to the interface and the actuation arrangement to determine a delivery command based at least in part on the calibration data and operate the actuation arrangement in accordance with the delivery command.
A system comprising:
- a consumable including tubing for dispensing a fluid and a readable element maintaining calibration data characterizing a relationship between delivery of the fluid and actuation of a peristaltic pumping mechanism;
- and
- an infusion device including an interface to obtain the calibration data from the readable element, an actuation arrangement configured to actuate the peristaltic pumping mechanism and a control module coupled to the interface and the actuation arrangement to determine a delivery command based at least in part on the calibration data and operate the actuation arrangement in accordance with the delivery command.
An infusion device comprising:
- a housing including a portion for receiving a consumable, the consumable including a conduit for fluid exiting a reservoir contained within the consumable;
- an interface proximate the portion of the housing to obtain calibration data from the consumable;
- an actuation arrangement contained within the housing and configured to actuate a peristaltic pumping mechanism operable to dispense the fluid via the conduit;
- and
- a control module coupled to the interface and the actuation arrangement to determine a delivery command based at least in part on the calibration data and operate the actuation arrangement in accordance with the delivery command.
