Abstract

A medical device module for use in a system with a remote programmer and/or a personal data assistant (PDA) with at least one medical device includes a housing, at least one medical device and a processor. The housing is adapted to couple with the PDA. The at least one medical device interface is coupled to the housing for interfacing with the at least one medical device. The processor is coupled to the at least one medical device interface to process data from the at least one medical device. The processor is also capable of interfacing with the PDA.

Claims

1. A medical system, comprising:

an external infusion device to deliver insulin to a user;

an external characteristic meter to receive a blood sample from the user to determine a glucose level of the user;

a sensor set to determine body characteristics on a continuous, near continuous, or intermittent basis, wherein the body characteristics include glucose levels of the user, the sensor set is coupled to a telemetered characteristic monitor transmitter to transmit sensor data including the body characteristics, and wherein the sensor set includes one of an implantable sensor, a subdermal sensor, and a subcutaneous sensor; and

a characteristic monitor, including

a display having a touch screen to display the sensor data received from the sensor set,

a sensor interface to wirelessly receive the sensor data from the sensor set via the telemetered characteristic monitor transmitter, and

a microprocessor to program and obtain data from the external infusion device, to coordinate the sensor data from the sensor set and meter data, including the determined glucose level of the user, from the external characteristic meter with the data from the external infusion device, to program and control the external infusion device, and to update delivery parameters of the external infusion device.

2. The medical system of claim 1, wherein the microprocessor further updates and programs the telemetered characteristic monitor transmitter.

3. The medical system of claim 1, wherein the microprocessor further operates to download data or upload programming instructions to a computer.

4. The medical system of claim 1, wherein the microprocessor further stores the sensor data obtained from the sensor set and provides the sensor data to the external infusion device or a computer.

5. The medical system of claim 1, where the display further displays at least one of trending information of the body characteristics, graphs of historical data, and average body characteristic levels.

6. The medical system of claim 1, wherein the microprocessor processes the sensor data received from the sensor set to determine when the characteristic meter is to be used to perform calibration of the sensor data.

7. The medical system of claim 1, wherein the characteristic meter utilizes a test strip to analyze the blood sample to determine the glucose level of the user.

8. A characteristic monitor, comprising:

a display having a touch screen to display sensor data received from a sensor set, wherein the sensor set determines body characteristics on a continuous, near continuous, or intermittent basis, the body characteristics include glucose levels of a user, the sensor set is coupled to a telemetered characteristic monitor transmitter to transmit the sensor data including the body characteristics, and wherein the sensor set includes one of an implantable sensor, a subdermal sensor and a subcutaneous sensor;

a sensor interface to wirelessly receive the sensor data from the sensor set via the telemetered characteristic monitor transmitter; and

a microprocessor to program and obtain data from an external infusion device that delivers insulin to the user, to coordinate the sensor data from the sensor set and meter data from an external characteristic meter that receives a blood sample from the user to determine a glucose level of the user with the data from the external infusion device, to program and control the external infusion device, and to update delivery parameters of the external infusion device.

9. The characteristic monitor of claim 8, wherein the microprocessor further updates and programs the telemetered characteristic monitor transmitter.

10. The characteristic monitor of claim 8, wherein the microprocessor further operates to download data or upload programming instructions to a computer.

11. The characteristic monitor of claim 8, wherein the microprocessor further stores the sensor data obtained from the sensor set and provides the sensor data to the external infusion device or a computer.

12. The characteristic monitor of claim 8, where the display further displays at least one of trending information of the body characteristics, graphs of historical data, and average body characteristic levels.

13. The characteristic monitor of claim 8, wherein the microprocessor processes the sensor data received from the sensor set to determine when the characteristic meter is to be used to perform calibration of the sensor data.

14. The characteristic monitor of claim 8, wherein the characteristic meter utilizes a test strip to analyze the blood sample to determine the glucose level of the user.
