External infusion device with remote programming, bolus estimator and/or vibration alarm capabilities

摘要

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.

主权项

1. An external infusion system comprising:
a remote RF programmer that includes
a programmer housing,a programmer processor contained within the programmer housing,a programmer memory contained within the programmer housing, the programmer memory storing program instructions executed by the programmer processor, andan indication device that provides a first tactile indication of a condition of the external infusion system;a bolus estimator to calculate a correction bolus based on (i) a pre-programmed carbohydrate ratio, (ii) a pre-programmed insulin sensitivity, (iii) current blood glucose, (iv) target blood glucose, and (v) carbohydrates to be consumed, wherein the bolus estimator is programmed with the remote RF programmer; andan external infusion device that includes
a device housing having a keypad, anda fluid reservoir contained within the device housing; wherein the infusion device receives commands or instructions from the remote RF programmer to deliver the calculated correction bolus from the fluid reservoir.
