Abstract

A controller for a programmable medical pump is configured to select a drug library file that corresponds to a received medication name and determine a number of times status information is received within a designated time period from a current time during an infusion therapy. The example controller is also configured to determine if the number of times the status information is received comports with an accumulated medication dosage limit using a dose per administration program parameter. Responsive to the number of times the status information is received matching or exceeding the accumulated medication dosage limit, the controller is configured to prevent another administration of the medication until enough time has passed such that the number of times the status information has been received within the designated time period from the current time is less than the accumulated medication dosage limit.

wherein the controller is further configured to;

determine if the number of times the status information is received comports with the soft accumulated medication dosage limit, and

responsive to the number of times the status information is received matching or exceeding the soft accumulated medication dosage limit but being less than the hard accumulated medication dosage limit, permit another administration of the medication and providing a soft alarm.

6. :

The infusion pump apparatus of claim 5, wherein providing the soft alarm includes at least one of;

displaying information indicative of the soft alarm via the interface, and

transmitting a message indicative of the soft alarm to at least one of a server or a personal digital assistant.

7. :

The infusion pump apparatus of claim 1, wherein the infusion pump apparatus includes a syringe pump, and wherein at least one of the memory, interface, and controller are located within the syringe pump.

8. :

An infusion pump apparatus for administrating an infusion therapy to a patient, the apparatus comprising;

a memory including

(i) drug library files each for a different medication, each of the drug library files including program parameter limits for the respective medication including a medication dosage limit, and

(ii) program parameters for controlling the administration of the infusion therapy according to received program parameter values including a time program parameter and a dose program parameter;

an interface configured to receive a medication name of a medication to be administered for the infusion therapy and related program parameter values including a time program parameter value and a dose program parameter value, and

a controller communicatively coupled to the interface and the memory and configured to;

select a drug library file that corresponds to the received medication name,

compare the dose program parameter value to the medication dosage limit,

administer the infusion therapy according to the received program parameter values if the dose program parameter value is less than the medication dosage limit, and

display a recommendation to at least one of increase the time program parameter value or decrease the dose program parameter value if the dose program parameter value is greater than the medication dosage limit.

9. :
