Abstract

An apparatus for delivering a bolus of a medical agent to a patient. The apparatus comprises a pump mechanism, a data input device, and a processor in data communication with the keypad and arranged to control the pump mechanism. The processor is programmed to receive data specifying a bolus amount through the data port, receive data regarding duration through the data port, receive a percentage through the data port, the percentage defining a portion of the bolus amount to deliver immediately upon executing a deliver command and a remainder of the bolus amount to deliver over the duration upon executing a deliver command, and execute the deliver command thereby controlling the pump mechanism to deliver the bolus. Also a method of temporarily adjusting the delivery rate of an infusion pump. The infusion pump is programmed to deliver a basal rate. The method comprises prompting a user to select whether to enter the temporary rate as a percent of the current delivery rate or as a new delivery rate; entering into the pump a period of time having a beginning and an end; entering into the pump a temporary basal rate; and delivering the therapeutic agent at a delivery rate substantially equal to the temporary basal rate during the period of time.

Claims

1. A method of delivering a bolus of a therapeutic agent from a medical pump based on a measured characteristic of a patient having an acceptable range, comprising:

measuring the characteristic of the body and determining whether the measured characteristic is within the acceptable range or not;

delivering a meal bolus if the measured characteristic is inside of the acceptable range, including programming a desired bolus amount and desired duration of bolus delivery into the pump and programming a percentage into the pump defining a portion of the bolus to deliver upon executing a deliver command and a remainder to deliver over the duration;

delivering a bolus if the measured characteristic is outside of the acceptable range, including displaying a desired bolus amount based on a correction factor defining the amount of change of the characteristic of the body per each unit of delivered therapeutic agent on average for a predetermined amount of time;

calculating a residual bolus value defining an estimate amount of any previously delivered bolus still active in the patient;

calculating and displaying an adjusted bolus amount based on a difference between the desired bolus amount and the residual bolus value prior to executing the deliver command; and

executing the deliver command.
