US 2014/0275872 A1 · SYSTEMS AND METHODS FOR TESTING PATIENT MONITORS

Abstract

A quality control system for patient monitors is disclosed. The quality control system can include a quality check insert having optical properties. In an embodiment, the insert is placed within a sensor, irradiated with light, and then the light is detected after attenuation by the insert. The detected light is processed using the same or different processing methodologies typically used to determine measurement values for physiological parameters of a monitored patient. When a patient monitor is functioning properly, the results of the processing provide values within a predetermined range of values. When the patient monitor is not functioning properly, the results of the processing provide values outside the predetermined range of values. The quality control system can include quality control parameters indicative of a properly functioning active pulse motor of the sensor, emitters of the sensor, detectors of the sensor, accelerometers of the sensors, and/or temperature sensors of the system.

Dependent claims

A quality control system comprising:

a noninvasive optical sensor configured to detect light attenuated by body tissue of a patient and output a detector signal responsive to the detected light;
a patient monitor configured to process the detector signal to determine measurement values for one or more physiological parameters of the patient;
and
an insert shaped generally to mechanically mate with surfaces of the optical sensor, the insert having optical properties, wherein when the insert is properly placed within the sensor and irradiated by the sensor, the monitor processes detector signals, wherein the patient monitor provides display indicia indicative of whether the processed detector signals generate values within a predetermined range of values, the predetermined range associated with the optical properties of the insert.
