First Claim
Patent Images
1. A method of administering medicinal fluid to a user, comprising:
- delivering a medicinal fluid from a wearable pump system to the user;
detecting an activity level of the user using an activity sensor in the pump system;
querying the user on a user interface of the pump system to confirm whether the detected activity level of the user represents an actual activity level of the user;
prompting the user for user input on a user interface of the pump system to authorize a decrease in the delivery of medicinal fluid that is determined in response to said detected activity level; and
adjusting the delivery of medicinal fluid from the pump system to the user in response to the user input that authorizes said decrease in the delivery of medicinal fluid.

Abstract
Some embodiments of a wearable infusion pump system can include a pump device having a drive system to dispense a medicine to a user, an activity sensor that detects a possible change in an activity level of the user, and a controller to activate the drive system to dispense the medicine to the user. The controller device can query the user to indicate whether a detected activity level of the user represents an actual change in the activity level of the user. The controller device can alter the medicine dispensing schedule based on the user indicated changes in activity level.

9. A method of administering medicinal fluid to a user, comprising
delivering a medicinal fluid from a wearable pump system to the user; -
detecting an activity level of the user using an activity sensor in the pump system; storing data correlating activity levels of the user to changes in the need for medicinal fluid of the user, wherein the stored data comprises an activity level to glucose ratio, the data being stored in computer-readable memory of the pump system; querying the user on a user interface of the pump system to indicate whether the detected activity level of the user represents an actual activity level of the user; and adjusting the delivery of medicinal fluid from the pump system to the user based on the detected activity level of the user and the stored data correlating activity levels to changes in the need for medicinal fluid. - View Dependent Claims (10, 11, 12, 16)

17. A method of administering medicinal fluid to a user, comprising:
-
delivering a medicinal fluid from a wearable pump system to the user, wherein delivering the medicinal fluid to the user comprises dispensing the medicinal fluid from a disposable and non-reusable pump device of the wearable pump system that receives control signals from a reusable controller device removably attached to the disposable and non-reusable pump device, wherein the disposable and non-reusable pump device of the wearable pump system receives the control signals from the reusable controller device via a first electrical connector of the pump device that mates with a second electrical connector of the controller device when the controller and the pump device are removably attached in a fixed relationship; detecting an activity level of the user using an activity sensor in the pump system; storing data correlating activity levels of the user to changes in the need for medicinal fluid of the user, the data being stored in computer-readable memory of the pump system; and querying the user on a user interface of the pump system to indicate whether the detected activity level of the user represents an actual activity level of the user; and adjusting the delivery of medicinal fluid from the pump system to the user based on the detected activity level of the user and the stored data correlating activity levels to changes in the need for medicinal fluid. - View Dependent Claims (18, 19, 20, 22, 23)
