Infusion pump and method with dose-rate calculation
First Claim
1. A method of operating an infusion pump comprising the steps of:
- (a) prompting a user of the infusion pump to input a plurality of infusion parameters into the infusion pump, said plurality of infusion parameters including an intended drug dose of a drug to be administered to a patient;
(b) calculating a drug flow rate based upon said plurality of infusion parameters input by the user during said step (a);
(c) rounding said drug flow rate calculated in said step (b) to generate a rounded drug flow rate;
(d) calculating an actual drug dose from said rounded drug flow rate, said actual drug dose representing the actual drug dose to be infused to the patient; and
(e) generating a visual display of said actual drug dose to allow the user to compare said actual drug dose with said intended drug dose.

Abstract
An infusion pump and method of operating an infusion pump in which the user of the infusion pump is prompted to input a number of infusion parameters, which include a dose mode, a drug dose, a drug amount, and a drug volume. After the parameters are input by the user, the infusion pump automatically calculates an infusion rate corresponding to the desired drug dose input by the user. The infusion pump, which includes a fluid pump, may round the calculated infusion rate to conform it to a flow rate which the fluid pump can deliver. If the infusion rate is rounded, the infusion pump calculates the actual drug dose from the rounded infusion rate and displays the actual dose on a visual display to allow the user of the infusion pump to determine how much the actual dose varies from the intended dose input by the user. After the actual dose is determined, the infusion pump continuously infuses the patient with the drug at the displayed infusion rate.

19. A method of operating an infusion pump comprising the steps of:
-
(a) prompting a user of the infusion pump to input a plurality of infusion parameters into the infusion pump, said plurality of infusion parameters including a dose mode being selectable from a plurality of dose nodes including a first dose mode which is based upon the weight of a patient to be infused by the infusion pump and a second dose mode which is not based upon the weight of a patient to be infused by the infusion pump; (b) determining whether the user input said first dose mode to the infusion pump or said second dose mode to the infusion pump; (c) prompting the user for the weight of the patient only if the user input said first dose mode; (d) calculating a drug flow rate based upon said plurality of infusion parameters input by the user; and (e) continuously infusing the patient with said drug over a period of time based upon said drug flow rate calculated in said step (d). - View Dependent Claims (20, 21, 22, 23, 24, 25, 26)

27. An infusion pump for the continuous infusion of a drug from a drug source into a patient over a period of time, said infusion pump comprising:
-
pump means for continuously infusing the patient with the drug over a first period of time; means for prompting a user of said infusion pump to input a dose mode to said infusion pump while the patient is being infused with the drug by said pump means; means for prompting the user to input an intended drug dose to said infusion pump while the patient is being infused with the drug by said pump means; means for prompting the user to input a drug amount to said infusion pump while the patient is being infused with the drug by said pump means; means for prompting the user to input a drug volume to said infusion pump while the patient is being infused with the drug by said pump means; means for determining whether the user input a dose mode requiring the body weight of the patient; means for prompting the user to input the body weight of the patient to said infusion pump only if the user selected a dose mode based on the body weight of the patient; means for determining a drug infusion rate based upon said dose mode, said drug dose, said drug amount, and said drug volume input by the user; means for rounding said drug infusion rate to generate a rounded drug infusion rate; means for calculating an actual drug dose from said rounded drug infusion rate, said actual drug dose representing the actual drug dose to be infused to the patient over a second period of time; and display means for generating a visual display of said actual drug dose to allow the user to compare said actual drug dose with said intended drug dose, said pumping means infusing the patient with the drug in accordance with said drug infusion rate over said second period of time.
