Calibration resistance emulator
First Claim
1. A resistance emulator comprising:
- a first plug configured to couple with a medical monitor configured to receive a calibration resistance value from a coded resistor of a medical sensor, wherein the first plug comprises a first plurality of pins in a pin configuration;
a second plug configured to couple with a medical sensor configured without the coded resistor, wherein the second plug comprises a second plurality of pins in the pin configuration; and
emulation circuitry configured to receive calibration data from a memory of the medical sensor through a first pin and a second pin of the first plurality of pins and to provide a signal correlative to the calibration resistance value to the medical monitor through a third pin of the second plurality of pins, wherein the first, second, and third pins each comprise a different pin position in the pin configuration.

Abstract
The present disclosure relates generally to patient monitoring systems and, more particularly, to a resistance emulator for patient monitors. In an embodiment, a resistance emulator includes a first plug configured to couple with a medical monitor. The medical monitor is configured to receive a calibration resistance value of a medical device sensor from a coded resistor. The resistance emulator further includes a second plug configured to couple with a medical device sensor. The medical device sensor is configured without the coded resistor. The resistance emulator also includes emulation circuitry configured to provide an emulated signal representative of the calibration resistance value to the medical monitor.
