Multi-parameter capability transmitter for wireless telemetry systems
First Claim
1. A transmitter of a wireless telemetry system (100) for medical applications, the transmitter comprising:
- a processing unit (160);
a data transmission unit (140) in communication with the processing unit (160), said data transmission unit being adapted for providing a wireless transmission to a receiver (150) of the telemetry system (100), a locally attached sensor (120) that communicates with the processing unit (160), wherein the processing unit, data transmission unit and locally attached sensor are arranged in a common housing without any wires attached to the processing unit, data transmission unit and locally attached sensor extruding from the housing; and
a coupling unit (170) for selectively coupling one of;
(1) a plurality of remote sensors (200i) and (2) the locally attached sensor (120) via a selecting unit (210) to the processing unit (160) based on predetermined criteria, so that a sensor signal indicative of an alert condition having a highest level of priority is coupled to the data transmission unit (140).

Abstract
A transmitter 110 physically comprises a (local) sensor 120, normally located within a transmitter casing 130, for sensing a first parameter, a data transmission unit 140 for providing a wireless transmission to a receiver 150 of the telemetry system 100, and a coupling unit 170 for coupling one or more remote sensors 200i to the transmitter. While the transmitter is designed to transmit signals from the local sensor, it also allows to further or alternatively transmit signals from one or more remote sensors coupled to the coupling unit. This allows changing monitoring from one parameter to another parameter by simply coupling another remote sensor to the coupling unit.

19. A wireless telemetry system (100) for medical applications, comprising:
-
a transmitter (110) having a plurality of sensors electrically coupled thereto for selectively transmitting data from at least one of the plurality of said sensors according to predetermined criteria so that data relating to a sensor that is in an alert condition has priority in being transmitted; and
