1. A patient monitoring system configured with improved quality control of its accessories through accessory authorization, the system comprising:
- a noninvasive sensor including a sensor information element storing sensor information;
a cable, separate from and connectable with said noninvasive sensor including an information element storing cable information governing which information must at least be found in said sensor information;
a patient monitor configured to receive a signal indicative of one or more physiological parameters of a patient from the sensor through the cable, the patient monitor further configured to acquire the cable information stored in the information element of the cable, to acquire sensor information from the noninvasive sensor, and to determine, based at least in part on the acquired cable and sensor information, whether the sensor and cable are compatible based on the acquired information.

Abstract
A system and method to help maintain quality control and reduce cannibalization of accessories and attached probes in a highly sensitive patient monitor, such as a pulse oximetry system. One or more attached components may have information elements designed to designate what quality control mechanisms a patient monitor should look to find on that or another component or designate other components with which the one component may properly work. In a further embodiment, such information elements may also include data indicating the appropriate life of the component.

11. A patient monitor system configured to ensure fidelity and compatibility in sensors accessories used by the monitor and to acquire sensor signals indicative of light attenuated by body tissue, the patient monitor system comprising:
- a first accessory including a first information element storing first information;
a second accessory including a second information element storing second information;
said first accessory and said second accessory are connectable to each other; and
a patient monitor configured to communicate with said first accessory and said second accessory via said first accessory;
wherein said patient monitor is configured to compare said first information with said second information and to determine, based at least in part on a result of the comparison, whether said first accessory and said second accessory are compatible with each other and with the patient monitor. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
