A portable medical device is operated in an active mode in which the device receives a user input at an input interlace and provides the received user input to a processor of the device. The active mode is terminated and the device is operated in a safe mode, in which the received user input is not provided to the processor and/or one or more device function is disabled, in response to determining that the received user input was received in an out of bounds region of the input interface. The safe mode is terminated in response to receiving a predetermined user input comprising an activation input.

1. A portable ambulatory infusion system, 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, the touchscreen adapted to display a plurality of input screens and receive touch input from a user on the plurality of input screens;a memory adapted to store operating parameters and settings relating to use of the delivery mechanism; anda processor disposed in the housing and configured to control operation of the portable ambulatory infusion system in an active mode and a safe mode, wherein in the safe mode the processor disables at least one ambulatory infusion system operation that is active in the active mode, the processor further configured to: define one or more active areas on the plurality of input screens configured to receive touch input with selectable icons from the user for the ambulatory infusion system operation;define one or more out of bounds regions associated with corresponding input screens in the memory, wherein the one or more out of bounds regions displayed on the corresponding input screen are defined as areas of the corresponding input screen that are not the one or more active areas associated with the selectable icons configured to receive control input from the user on the corresponding input screen;identify a touch input on the touchscreen on one of the plurality of input screens that is in at least one of the one or more out of bounds regions of the corresponding input screen while the portable ambulatory infusion system operation is in the active mode;suspend the ambulatory infusion system operation in the active mode and place the ambulatory infusion system operation in the safe mode in response to the touch input received in the at least one of the one or more out of bounds regions that are not the one or more active areas associated with the selectable icons, including disabling at least one of the one or more active areas on the corresponding input screen from receiving touch input. 2. The portable ambulatory infusion system of claim 1, wherein the processor is further configured to terminate the safe mode and return to the active mode upon identifying a touch input at the touchscreen as a predetermined activation input. 3. The portable ambulatory infusion system of claim 2, wherein the predetermined activation input comprises selection of a wake display icon on the user interface. 4. The portable ambulatory infusion system of claim 2, wherein the predetermined activation input comprises a predetermined sequence of selected icons on the user interface. 5. The portable ambulatory infusion system of claim 4, wherein the predetermined sequence comprises a series of distinct touch inputs each separated by no more than a maximum predetermined amount of time. 6. The portable ambulatory infusion system of claim 1, wherein the processor is further configured to display an unlock screen on the touchscreen after safe mode is entered. 7. The portable ambulatory infusion system of claim 1, wherein the processor defines one or more of the out of bounds regions for the plurality of input screens, each of the one or more out of bounds regions customized for the corresponding input screen. 8. The portable ambulatory infusion system of claim 1, wherein the at least one ambulatory infusion system operation that is disabled in the safe mode is an operation of the delivery of the fluid by the delivery mechanism. 9. The portable ambulatory infusion system of claim 1, wherein the at least one ambulatory infusion system operation that is disabled in the safe mode is alteration of the operating parameters and settings of the portable ambulatory infusion system stored in the memory. 10. The portable ambulatory infusion system of claim 1, wherein the touchscreen is disposed on the housing. 11. The portable ambulatory infusion system of claim 1, wherein the touchscreen is disposed on a separate device remote from the housing and the processor is adapted to receive information related to the touch input on the touchscreen wirelessly from the separate device. 12. A portable ambulatory infusion pump, comprising: a processor that controls operation of the portable ambulatory infusion pump in a plurality of operating modes that include an active mode in which multiple ambulatory infusion pump components are operated and a safe mode in which at least one ambulatory infusion pump component is deactivated and not operated;an input interface through which the processor receives user input, the input interface comprising a touchscreen adapted to receive touch input from a user, wherein the processor defines one or more active areas of the input interface configured to receive the touch input for portable ambulatory infusion pump operation;wherein the processor defines out of bounds regions associated with the input interface in the memory and each of the out of bounds regions of the input interface being a non-active area of the input interface that is not configured to receive touch input from the user for portable ambulatory infusion pump operation, andwherein the processor terminates the active mode and operates the ambulatory infusion pump in the safe mode in response to determining that a received touch input was an accidental interaction with the input interface received in one of the out of bounds regions of the input interface defined as one of the non-active areas, andwherein operating the portable ambulatory infusion pump in the safe mode in response to the user input in the one of the out of bounds regions defined as one of the non-active areas includes locking the touchscreen from receiving touch input at the one or more active areas. 13. The portable ambulatory infusion pump of claim 12, wherein the processor terminates the safe mode in response to receiving an activation user input through the input interface comprising a predetermined activation input. 14. The portable ambulatory infusion pump of claim 13, wherein the activation input comprises selection of a wake display icon of the input interface. 15. The portable ambulatory infusion pump of claim 13, wherein the activation input comprises a predetermined sequence of selected icons on the input interface. 16.
