Abstract

Medical device data is transferred using a universal adaptor between an implanted medical device and hospital monitoring systems. The universal adaptor is an interface compatible with various built-in hospital monitoring network comprised of equipment from a variety of manufacturers. The universal adaptor includes a telemetry circuitry, a calibration system for atmospheric pressure and an analog interface. The calibration system relates to barometric correction and includes an external pressure reference system.

Claims

1. A universal interface for an IMD data management to enable physiologic data transfer from the IMD to hospital systems via various built-in monitoring equipment, the universal interface comprising:

a telemetry circuitry in communication with and configured to receive hemodynamic pressure data from the IMD;

means for calibration of the hemodynamic pressure data with ambient barometric pressure; and

means for transmitting the calibrated hemodynamic pressure data from the universal interface to an external hospital monitor in a data format compatible with the external hospital monitor.

2. The universal interface of claim 1, wherein said means for calibration includes an external pressure reference.

3. The universal interface of claim 1, wherein said telemetry circuitry includes wireless communications with the IMD.

4. The universal interface of claim 1, wherein the external hospital monitor is a bedside monitor.

5. The interface of claim 1, wherein the data format corresponds to an Abbot Critical Care Transpac IV format.

6. A medical data transfer and exchange system including an IHM/IMD, wherein a universal interface connects the system to a network of hospital monitors comprising:

a telemetry system to wirelessly retrieve the medical data from the IHM/IMD;

the universal interface being in data communications with the telemetry system and configured to correlate the medical data to a format; and

the network of hospital monitors being in data communications with the IHM/IMD via said universal interface, wherein the universal interface transmits the medial data to the network in date format compatible with the network.

7. The system of claim 6, wherein said universal interface includes a telemetry circuitry.

8. The system of claim 6, wherein said universal interface includes means for calibration of barometric pressure.

9. The system of claim 6, wherein said universal interface includes an analog interface adapted to connect to the network of hospital monitors.

10. The system of claim 6, wherein said universal interface includes said network of hospital monitors which includes equipment manufactured by various manufacturers.

11. The system of claim 10, wherein said equipment includes various connection and porting standards.

12. The system of claim 6, wherein said network of hospital monitors includes bedside modules located proximate to a patient or in a patient'"'"'s room.

13. The system of claim 6, wherein the data format corresponds to an Abbot Critical Care Transpac IV format.

14. A universal system for acquiring physiologic signals from an IMD/IHM and transmitting the signals to one or more monitoring devices distributed in a hospital monitoring network, the system in continuation with the network comprising:

a physiologic signal originating from the IMD/IHM;

means for retrieving the physiologic signals; and

means for conditioning the signals for transmission to said one or more monitoring devices.

15. The system of claim 14, wherein said means for retrieving includes a telemetry circuitry.

16. The system of claim 14, wherein said means for conditioning the signals includes a universal interface.

17. The system of claim 14, wherein said one or more monitoring devices include a variety of modules made by various manufacturers.

18. The system of claim 14, wherein the means for conditioning include formatting the signal into a format compatible with an Abbot Critical Care Transpac IV format.
