Parameter input for drug delivery pump
First Claim
1. A method for input of a desired value for a parameter used to control a medical device, comprising the steps of:
- (a) defining a set of values for said parameter, said values increasing in unequal increments and being selected for inclusion in the set based upon a frequency of use in controlling the medical device, said values in said set being used substantially more often than other values not included in the set;
(b) providing a dedicated quick entry control on the medical device that when actuated by an operator scrolls through said set of values displaying successive values from said set, said successive values that are displayed being independent of a rate at which said quick entry control is actuated by the operator; and
(c) employing a value that is displayed for the parameter, for use in controlling the medical device.

Abstract
Parameters for controlling a drug infusion pump (10) are selected by scrolling through sets of predefined values. A value for either a rate and/or a volume of a fluid to be infused (VTBI) is displayed by pressing a quickset key (38) on a control panel (18) of the pump. Each time that the quickset key is depressed, the value appearing on a display (22) changes to the next value in the corresponding predefined set of values. It is also contemplated that holding the quickset key depressed for at least a predetermined time will cause the display to continuously scroll through successive values from the set of predefined values. The predefined values are selected in the set because they represent the most common values for the parameters used by the pump. An operator can "fine tune" the displayed value to a desired value that is not in the set of predefined values by pressing either a down arrow key (50) or an up arrow control key (52). Using this method and system, the values of the parameters are rapidly entered with minimal chance of error.

8. A control for a medical device that enables entry of a desired value for a parameter used to control the medical device, comprising:
-
(a) a microprocessor programmed to respond to the desired value of the parameter entered by an operator to control the medical device; (b) a memory, which is coupled to the microprocessor, for storing a program executed by the microprocessor to control the medical device, and for storing a set of predefined values for the parameter, said predefined values increasing in unequal increments and being selected based upon a frequency of use in controlling the medical device, said set of predefined values being used for the parameter controlling the medical device substantially more often than other values that are not included in the set; (c) a control panel that includes a dedicated quick entry control, which when actuated by the operator, scrolls through the set of values; and (d) a display for displaying successive values for the parameter as the operator scrolls through the predefined values, said successive values that are displayed being independent of a rate at which the operator actuates said quick entry control, a value displayed being used by the microprocessor for the parameter used in controlling the medical device. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
