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.

The apparatus of claim 6 wherein the data input device is a keypad having one or more buttons.8. The apparatus of claim 6 wherein the data input device is a data port configured to communicate with a computer.9. The apparatus of claim 6 wherein the processor is further programmed to control the pump mechanism to simultaneously deliver a basal and the bolus upon executing the deliver command.10. A method of temporarily adjusting the delivery rate of an infusion pump, the infusion pump programmed to deliver a basal rate, the method comprising: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. 11. The method of claim 10 further comprising:selecting to enter the temporary basal rate as a new delivery rate; and wherein entering into the pump a temporary basal rate includes entering into the pump a new delivery rate, thereby changing the basal rate to the new delivery rate for period of time. 12. The method of claim 10 further comprising:selecting to enter the temporary basal rate as a percent; and wherein entering into the pump a temporary basal rate includes entering into the pump a percentage by which to adjust the basal rate for the period of time thereby establishing the temporary basal rate. 13. The method of claim 12 wherein entering into the pump a percentage by which to adjust the basal rate includes entering a percentage greater than 100%.14. The method of claim 12 wherein entering into the pump a percentage by which to adjust the basal rate includes entering a percentage less than 100%.15. The method of claim 12 further comprising:delivering a therapeutic agent at a delivery rate substantially equal to the basal rate before the beginning of the period of time; and delivering the therapeutic agent at the delivery rate substantially equal to the basal rate after the end of the period of time. 16. The method of claim 15 further comprising calculating the temporary delivery rate upon entering into the pump a percentage by which to adjust the basal rate according to the equation: where Percent is the percentage by which to adjust the basal rate.17. An apparatus for delivering a therapeutic agent at a basal rate, the apparatus comprising: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 being programmed to prompt a user to select whether to enter the temporary rate as a percent of the current delivery rate or as a new delivery rate, receive from the data input device a period of time having a beginning and an end and a temporary basal rate, and control the pump mechanism to deliver the therapeutic agent at a delivery rate substantially equal to the temporary basal rate during the period of time. 18.
