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

1. An external infusion device for infusing insulin into a body of a user from a reservoir, the external infusion device comprising:

a device housing for use on an exterior of the body and sized to be held in a hand of the user;

a drive mechanism at least partially contained within the housing and operatively coupled to the reservoir for infusing insulin into the body of the user from the reservoir;

a processor contained within the housing and coupled to the drive mechanism;

a memory contained within the housing and coupled to the processor for storing a target glucose level, an insulin sensitivity, and a carbohydrate ratio of the user;

a display device contained within the housing and coupled to the processor for displaying information to the user, wherein the display device includes a touch screen input device for enabling the user to input a current glucose level of the user and carbohydrates being consumed by the user; and

a bolus estimator contained within the housing and used in conjunction with the processor and the display device including the touch screen input device to calculate a bolus of insulin to be infused based upon the current glucose level, the target glucose level, the insulin sensitivity, the carbohydrates being consumed, and the carbohydrate ratio, wherein the calculated bolus of insulin to be infused is provided to the user on the display device.

2. The external infusion device of claim 1, wherein the touch screen input device further enables the user to input the target glucose level, the insulin sensitivity, and the carbohydrate ratio of the user.

3. The external infusion device of claim 1, wherein the memory further stores an insulin duration factor for the user, and wherein the bolus estimator calculates the bolus of insulin to be infused based upon the current glucose level, the target glucose level, the insulin sensitivity, the carbohydrates to be consumed, the carbohydrate ratio, and the insulin duration factor.

4. The external infusion device of claim 1, wherein the touch screen input device further enables the user to input the insulin duration factor for the user.

5. The external infusion device of claim 1, wherein the touch screen input device further enables the user to accept or adjust the bolus of insulin to be infused calculated by the bolus estimator.

6. The external infusion device of claim 1, wherein the display device provides visual alerts to the user.

7. The external infusion device of claim 1, further comprising a vibration alarm contained within the housing for providing tactile alerts to the user.

8. The external infusion device of claim 1, further comprising an audible alarm contained within the housing for providing audible alerts to the user.

9. The external infusion device of claim 1, further comprising:

a vibration alarm contained within the housing for providing tactile alerts to the user; and

an audible alarm contained within the housing for providing audible alerts to the user.
