Interface and related method for connecting sensor equipment and a physiological monitor

摘要

An interface to connect sensor equipment and a physiological monitor includes a first connector to receive power from a first channel of the monitor and a second connector to receive power from a second channel of the monitor. The power from each of the first and second channels of the monitor is combined within the interface. The interface further includes a third connector to provide the combined power to the sensor equipment; a voltage converter to rescale the voltage of the combined power that is provided to the sensor equipment; and a scaling circuit to reduce the voltage of a signal representing a measured physiological parameter. The signal representing the measured physiological parameter is sent from the sensor equipment to the monitor. The interface is advantageous to allow sensor equipment to be sufficiently powered by a monitor that would not typically provide enough power.

1. A cable comprising:
a first connector configured to receive power from a first channel of a physiological monitor and a second connector configured to receive power from a second channel of the monitor, wherein the power from each of the first and second channels of the monitor is combined within the cable; a third connector configured to provide the combined power to a receiver configured to receive information representing a measured physiological parameter and generate a signal representing the measured physiological parameter; a voltage converter configured to rescale the voltage of the combined power that is provided to the receiver; wherein the cable is configured to receive the signal representing the measured physiological parameter that is generated by the receiver, and wherein the cable is configured to provide a signal representing the measured physiological parameter to the monitor via the first connector and/or the second connector.
