Abstract: A radiofrequency adapter for medical monitoring equipment which includes a controller which is physically connected to a sensor, and an integrator which is physically connected to a medical monitor; the controller and the integrator are physically separated; the controller provides signal receiving means which receive the signals generated by the sensor, signal conditioning and digitising means, and a radiofrequency transmitter connected to the conditioning and digitising means and arranged to transmit the digitised signals across a wireless radiofrequency link to a radiofrequency receiver incorporated in the integrator; the integrator also includes means for reconstructing the received digital signals back to an analogue signals and means for transmitting the reconstructed and an analogue signals to a monitor physically connected to the integrator.
