Abstract

An infusion pump which includes a fingerprint reader to verify that a patient or a user is authorized to activate a patient-controlled analgesic button. The fingerprint reader can be integrated into the patient-controlled analgesic button. The infusion pump delivers a dose of medication to the patient if the fingerprint of the patient or user matches a pre-loaded fingerprint.

Claims

1. An infusion pump comprising:

a housing;

a pump actuator located within the housing;

a user interface programmed to control the pump actuator; and

a patient controlled analgesic button including a fingerprint reader, the patient controlled analgesic button connected operably to the user interface via a cord, the patient controlled analgesic button and the fingerprint reader configured to selectively enable operation of the pump actuator.

2. The infusion pump of claim 1, wherein a patient'"'"'s fingerprint is pre-loaded into pump software of the user interface.

3. The infusion pump of claim 1, wherein the fingerprint reader is configured to read a patient'"'"'s thumbprint.

4. An infusion pump comprising:

a pump actuator, a user interface programmed to control the pump actuator, a patient-controlled analgesic button including a fingerprint reader, the patient controlled analgesic button connected operably to the user interface via a cord, and wherein the user interface is programmed to;

read a user'"'"'s fingerprint inputted via the reader when the user activates the patient-controlled analgesic button;

compare the user'"'"'s fingerprint to a pre-loaded fingerprint;

verify the user'"'"'s fingerprint matches the pre-loaded fingerprint; and

cause the pump actuator to deliver a dose of medication to a patient upon verification.

5. The infusion pump of claim 4, wherein the pre-loaded fingerprint is a thumbprint.

6. The infusion pump of claim 4, wherein the pre-loaded fingerprint is pre-loaded into pump software of a user interface of the infusion pump.

7. The infusion pump of claim 4, wherein the user is the patient.

8. A medical fluid delivery method comprising the steps of:

providing an infusion pump having a patient-controlled analgesic button which includes a fingerprint reader, the patient controlled analgesic button connected operably to the infusion pump via a cord;

reading a patient'"'"'s fingerprint using the fingerprint reader when the patient activates the patient-controlled analgesic button;

comparing the patient'"'"'s fingerprint to a pre-loaded fingerprint;

verifying the patient'"'"'s fingerprint matches the pre-loaded fingerprint; and

delivering a dose of medication to the patient using the infusion pump.

9. The medical fluid delivery method of claim 8, wherein reading the patient'"'"'s fingerprint includes reading a thumbprint.

10. The method of claim 8, which includes providing selective access to the patient-controlled analgesic button via the fingerprint reader.

11. The method of claim 8, which includes pre-loading the patient'"'"'s fingerprint into software of the infusion pump.
