Abstract

A telemetered characteristic monitor system includes a remotely located data receiving device, a sensor for producing signal indicative of a characteristic of a user, and a transmitter device. The transmitter device includes a housing, a sensor connector, a processor, and a transmitter. The transmitter receives the signals from the sensor and wirelessly transmits the processed signals to the remotely located data receiving device. The processor coupled to the sensor processes the signals from the sensor for transmission to the remotely located data receiving device. The data receiving device may be a characteristic monitor, a data receiver that provides data to another device, an RF programmer for a medical device, a medication delivery device (such as an infusion pump), or the like.

Claims

1. An external telemetered characteristic monitor system for monitoring a characteristic of a user, the system comprising:

a remotely located data device;

a sensor set supporting a sensor for producing a signal indicative of the characteristic of the user;

an external transmitter device coupled to the sensor set including;

a housing;

a sensor connector coupled to the housing and that is connectable to the sensor set to receive signals from the sensor;

a processor within the housing coupled to the sensor connector to process the signals from the sensor for delivery to the remotely located data device;

a transmitter coupled to the processor for wirelessly transmitting the processed signals to the remotely located data device, wherein the remotely located data device utilizes the received processed signals to determine a characteristic reading of the user; and

a rechargeable battery within the housing to power the transmitter and the sensor; and

an associated charger that mates with the sensor connector of the external transmitter device to recharge the rechargeable battery of the external transmitter device when needed.

2. The external telemetered characteristic monitor system according to claim 1, wherein the sensor set supports the external transmitter device when coupled to the sensor set.

3. The external telemetered characteristic monitor system according to claim 1, wherein the sensor is implantable in tissue selected from the group consisting essentially of subcutaneous, dermal, sub-dermal, intra-peritoneal and peritoneal tissue, and wherein the sensor connector is directly connected to the sensor externally of the body.

4. The external telemetered characteristic monitor system according to claim 1, wherein the charger detects when the external transmitter device is mated with the charger and automatically charges the rechargeable battery.

5. The external telemetered characteristic monitor system according to claim 1, wherein the charger has an indication device to communicate status of how the charger is charging the rechargeable battery.

6. The external telemetered characteristic monitor system according to claim 1, wherein the charger is battery-powered.
