AUTOMATED OXYGEN DELIVERY SYSTEM Russian patent published in 2015 - IPC A61M16/00 

FIELD: medicine.

SUBSTANCE: group of inventions refers to medical equipment. An automated oxygen delivery system comprises an patient's blood flow oxygen measuring sensor comprising a pulse oxymeter; a pneumatic sub-system comprising a gas feed connected to an oxygen inlet, an air inlet and a gas-mixture outlet for mixing oxygen and air to form gas mixture having the oxygen concentration delivered to the patient, and for delivering gas mixture to the patient; and a control sub-system connected to the sensor and the pneumatic sub-system comprising an input. A sensor interface is configured to receive the measurement data and the state information related to the sensor measurement data. The state information involves a perfusion index and a signal quality measure. A pneumatic sub-system interface is used to send commands and to receive the pneumatic sub-system data. A processor is connected to the input, the sensor interface and the pneumatic sub-system interface to control the supplied oxygen concentration on the basis of the required oxygen concentration, the measurement data and the state information. There are disclosed alternative versions of the automated system characterised by state information collecting media.

EFFECT: inventions provide the safe control of the supplied oxygen amount automatically.
