Sensor and vital sign information processing system

A vital sign information processing system comprising:

• a sensor configured to be attached to a living body;
• an information acquisition apparatus configured to acquire vital sign information of the living body through the sensor;
• a first memory disposed in the sensor, the first memory storing first site information indicative of a site at which the sensor is to be used;
• a second memory disposed in the information acquisition apparatus, the second memory storing second site information indicative of a site at which the information acquisition apparatus is to be used;
• and
• a processor disposed in the information acquisition apparatus,
• wherein the processor causes the information acquisition apparatus to perform a notification when the first site information and the second site information are not matched,
• wherein the notification is a visual notification, an audible notification, or a haptic notification,
• wherein the processor is configured to prohibit use of the sensor or limit a number of uses of the sensor, when the first site information and the second site information are not matched, and
• wherein the first site information is stored in the first memory during manufacturing of the sensor,
• wherein the site at which the sensor is to be used is a critical care medicine area, an intensive care unit, a neonatal intensive care unit, an operating room, a laboratory, a hospital ward, or a magnetic resonance imaging (MRI) room.
