ACCESSORY CONNECTION AND DATA SYNCHRONICATION IN A VENTILATOR

摘要

A medical ventilator (5) that includes a memory device (112), a controller (110) operatively coupled to the memory device (112), and an accessory connector (200) provided at or about the exterior of the ventilator housing. The controller (110) is adapted to record ventilation data in the memory device (112) that includes at least one of data relating to the operation of the ventilator (5) and data relating to the breathing of the patient while ventilation therapy is being provided to the patient. The accessory connector (200) is structured to operatively couple the controller (110) to an accessory device (205) and to provide power to the accessory device (205). The accessory connector (200) also serves as a communication bus for enabling the accessory device (205) to communicate data generated by it to the controller (110), which in turn is adapted to record the accessory device data in the memory device (112) in a manner wherein the accessory device data is merged.
