SYSTEM AND METHOD FOR REDUCTION OF INADVERTENT ACTIVATION OF MEDICAL DEVICE DURING MANIPULATION
First Claim
1. An ambulatory infusion pump, comprising:
- a housing;
a delivery mechanism at least partially contained within the housing and adapted to facilitate delivery of fluid to a user;
a user interface comprising a touchscreen disposed on a surface of the housing; and
a processor disposed in the housing and configured to generate menu screens for display on the touchscreen and to receive and process touch input from the touchscreen for navigation between or among the menu screens and for setting pump parameters, the processor further configured to;
receive touch input through the user interface indicating that an uninterrupted operation is to be performed on the pump;
automatically lock the touchscreen during the uninterrupted operation in response to the touch input such that touch input received at the touchscreen is not processed by the processor to navigate between or among menu screens or set pump parameters; and
unlock the touchscreen following completion of the uninterrupted operation.

Abstract
Inadvertent activation of a portable medical device such as an ambulatory infusion pump can be reduced by locking a touchscreen of the device when it is indicated that an uninterrupted operation is to be performed. When a processor receives a device operation input from the touchscreen that indicates an uninterrupted operation is to be performed on the portable device, the touchscreen is automatically locked such that touch input at the touchscreen is not processed by the processor to navigate between or among menu screens or set pump parameters. Following completion of the uninterrupted operation, the touchscreen can be unlocked. In one embodiment, the touchscreen can be unlocked by selection of an unlock icon on the touchscreen.

9. An ambulatory infusion system, comprising:
-
an infusion cartridge, the infusion cartridge including a reservoir for containing a fluid and an outlet adapted to be coupled to infusion tubing; a pump device configured to selectively receive the infusion cartridge and cooperate with the infusion cartridge to deliver fluid from the reservoir, out the outlet and through infusion tubing to a user; a user interface comprising a touchscreen disposed on a surface of the pump device; and a processor located in one of the infusion cartridge and the pump and configured to generate menu screens for display on the touchscreen and to receive and process touch input from the touchscreen for navigation between or among the menu screens and for setting pump parameters, the processor further configured to; receive touch input through the user interface indicating that an uninterrupted operation is to be performed on the pump; automatically lock the touchscreen during the uninterrupted operation in response to the touch input such that touch input received at the touchscreen is not processed by the processor to navigate between or among menu screens or set pump parameters; and unlock the touchscreen following completion of the uninterrupted operation. - View Dependent Claims (10, 11, 12, 13, 14, 15)
