Abstract

An infusion apparatus for infusing liquid into a patient over an infusion period beginning with an initial infusion and ending with a final infusion and during which infusion period all relevant infusion data is stored in a non-volatile memory to generate a complete historical record of the infusions administered during the infusion period. The infusion apparatus is provided with a housing, a pump disposed in the housing and adapted to pump liquid through a conduit, and a controller operatively coupled to the pump to cause the pump to deliver a plurality of infusions of liquid medicant during the infusion period, each of the infusions being made at a time and a flow rate. The infusion data stored in the non-volatile memory may include programmed infusion data input to the infusion pump during programming of the pump, the programmed data including data representing the infusion mode, the infusion flow rate, the volume to be infused, and the infusion start time. The infusion data may also include data representing the time at which each infusion was made during the infusion period and the flow rate at which of each infusion was made. The automatic recording of the infusion data during the programming and operation of the infusion apparatus will generate a complete historical data record, which is advantageous in that the data record can be later retrieved from the non-volatile memory and used for various purposes, including clinical purposes to aid in determining how effective a particular infusion therapy was and treatment purposes to confirm that the prescribed infusion was actually delivered to the patient.

Claims

1. A medical apparatus wit patient data recording for monitoring the patient, the medical apparatus comprising:

a housing;

a microprocessor disposed in said housing;

a input device coupled to said microprocessor;

a non-volatile memory coupled to said microprocessor;

a plurality of questions stored within the nonvolatile memory to be answered by the patient, said questions requesting information from the patient that is not associated with control parameters of the medical apparatus;

an electronic device coupled to said microprocessor for presenting at least one of said plurality of questions to the patient; and

,

a computer program stored within the memory that controls operation of the medical apparatus;

wherein the microprocessor is responsive to the computer program to present at least one of the plurality of questions via the electronic device, and to store in the non-volatile memory an answer to the question input through the input device to create a patient data record;

wherein the medical apparatus infuses liquid into a patient over an infusion period beginning with an initial infusion and ending with a final infusion, and wherein the medical apparatus delivers a plurality of infusions of the liquid during the infusion period beginning with the initial infusion and ending with the final infusion, each of the infusions made at a time and a flow rate.

2. The medical apparatus of claim 1, wherein the microprocessor stores infusion data in the non-volatile memory to generate an historical record of the plurality of infusions beginning with the initial infusion and ending with the final infusion.

3. The medical apparatus of claim 1, wherein the microprocessor generates an alarm upon the detection of an alarm condition.

4. The medical apparatus of claim 1, wherein the microprocessor is operatively coupled to a pump operated in any one of a plurality of infusion modes causing the pump to deliver a plurality of infusions of the liquid, in one of the infusion modes, during the infusion period beginning with the initial infusion and ending with the final infusion, each of the infusions made at a time and a flow rate.

5. The medical apparatus of claim 4, wherein the plurality of infusion modes includes a continuous infusion mode.

6. The medical apparatus of claim 4, wherein the plurality of infusion modes includes a ramp infusion mode.

7. The medical apparatus of claim 4, wherein the plurality of infusion modes includes a patient-controlled analgesic infusion mode.

8. The medical apparatus of claim 4, wherein the plurality of infusion modes includes a multiple period infusion mode.

9. The medical apparatus of claim 4, wherein the plurality of infusion modes includes an intermittent infusion mode.
