Abstract

A system for delivering a fluid to a patient includes a remote controller and an infusion pump. The infusion pump includes a dispenser for dispensing the fluid. An operationally-independent RF telemetry portion is configured to receive an RF data signal from the remote controller. An operationally-independent processing portion is configured to process the RF data signal received by the operationally-independent RF telemetry portion, and control the dispenser in accordance with the RF data signal received by the operationally-independent RF telemetry portion.

Claims

1. A system for delivering a fluid to a patient comprising:

a remote controller; and

an infusion pump including;

a dispenser for dispensing the fluid;

an operationally-independent RF telemetry portion configured to receive an RF data signal from the remote controller; and

an operationally-independent processing portion configured to process the RF data signal received by the operationally-independent RF telemetry portion, and control the dispenser in accordance with the RF data signal received by the operationally-independent RF telemetry portion.

2. The system of claim 1 wherein the operationally-independent processing portion includes:

an operationally-independent main processing unit, and

an operation-independent interlock processing unit.

3. A medical device comprising:

an operationally-independent RF telemetry portion configured to receive an RF data signal; and

an operationally-independent processing portion configured to process the RF data signal received by the operationally-independent RF telemetry portion.

4. The medical device of claim 3 wherein the operationally-independent processing portion includes:

an operationally-independent main processing unit; and

an operation-independent interlock processing unit.

5. The medical device of claim 3 wherein the operationally-independent RF telemetry portion include a boost circuit that is shielded from the operationally-independent processing portion.

6. The medical device of claim 3 wherein the RF data signal is broadcast in a non-restricted frequency band.

7. The medical device of claim 3 wherein the operationally-independent RF telemetry portion and at least a first portion of the operationally-independent processing portion are incorporated into a single microchip.

9. The medical device of claim 7 further comprising a compact antenna, which is external to the single microchip, electrically coupled to the operationally-independent RF telemetry portion, and allows for reception of the RF data signal.

10. The medical device of claim 9 wherein the compact antenna is a spirally-wound antenna.

11. The medical device of claim 9 wherein the compact antenna is a helically-wound antenna.

12. The medical device of claim 9 wherein an effective length of the compact antenna is a defined percentage of a wavelength of a carrier signal.

13. The medical device of claim 12 wherein the carrier signal is a 13.56 megahertz carrier signal and the operationally-independent RF telemetry portion is further configured to receive data encoded within the 13.56 megahertz carrier signal.

14. The medical device of claim 13 wherein the operationally-independent RF telemetry portion is further configured to transmit data encoded within the 13.56 megahertz carrier signal.

15. The medical device of claim 3 wherein the RF data signal includes a defined validation sequence and the operationally-independent RF telemetry portion is further configured to:

examine the RF data signal to confirm that the RF data signal includes the defined validation sequence.

16. The medical device of claim 15 wherein the operationally-independent RF telemetry portion is further configured to:

transmit an acknowledgement signal to the device transmitting the RF data signal if it is determined that the RF data signal includes the defined validation sequence.

17. The medical device of claim 3 further comprising:

a dispensing apparatus, responsive to the processing portion of the medical device, for dispensing medicament in accordance with the RF data signal.

18. The medical device of claim 17 wherein the medicament is insulin.
