Abstract

An infusion system for infusing a liquid into a body includes an external infusion device and a remote commander. The external infusion device includes a housing, a receiver, a processor and an indication device. The receiver is coupled to the housing and for receiving remotely generated commands. The processor is coupled to the housing and the receiver to receive remotely generated commands and to control the external infusion device in accordance with the commands. The indication device indicates when a command has been received and indicates when the command is being utilized to control the external infusion device so that the external infusion device is capable of being concealed from view when being remotely commanded. The remote commander includes a commander housing, a keypad for transmitting commands, and a transmitter for transmitting commands to the receiver of the external infusion device.

Claims

a housing adapted for use on an exterior of the body, wherein the housing is sized to contain at least a portion of the reservoir, wherein the drive mechanism is at least partially contained within the housing, wherein the drive mechanism operatively couples with the at least a portion of the reservoir within the housing, and wherein the housing is capable of being concealed from view on an individual;

a processor coupled to the housing;

a memory coupled to and used in conjunction with the processor to store at least two bolus infusion types;

wherein at least one of the two bolus types is square wave bolus;

a data receiving mechanism used in conjunction with the processor to select one of the at least two bolus types; and

an indication device that provides primarily tactile sensations to indicate the selected bolus type is being utilized or set,

wherein the processor controls the external infusion device in accordance with the selected one of the at least two bolus types.

2. An external infusion device according to claim 1, wherein the at least two bolus types are programmable by a user.

3. An external infusion device according to claim 1, wherein the data receiving mechanism is used to program the at least two bolus types.

4. An external infusion device according to claim 1, wherein the selected one of the at least two bolus types commences delivery after programming.

5. An external infusion device according to claim 1, wherein the indication device provides a primarily tactile sensation that buzzes.

6. An external infusion device according to claim 1, wherein the indication device provides an audio indication and a tactile indication.

7. An external infusion device according to claim 1, wherein the indication device provides a tactile indication that permits programming of the external infusion device while it is concealed from view on a user.

8. An external infusion device according to claim 1, wherein the data receiving mechanism is a keypad.

9. An external infusion device according to claim 1, wherein the data receiving mechanism is a remote commander.

10. An external infusion device according to claim 1, wherein the at least two bolus types may be set independently of each other.

11. An external infusion device according to claim 1, wherein the at least two bolus types are at least three bolus types.

12. An external infusion device according to claim 1, wherein the at least two bolus types are at least four bolus types.

13. An external infusion device according to claim 1, wherein the at least two bolus types include a bolus augmented with sensations that are selected from the group consisting of tactile, audio or visual.
