LIQUID ANAESTHETIC DISPENSER Russian patent published in 2013 - IPC A61M16/01 

FIELD: medicine.

SUBSTANCE: invention relates to medical equipment. A liquid anaesthetic dispenser comprises a vertical tube, a tube pressure sensor and an electronic control unit. The tube is connected through a hydraulic circuit with a liquid anaesthetic container by an inlet solenoid pass-stop valve, and with a mixing evaporator by an outlet solenoid pass-stop valve. The above solenoid valves and the tube pressure sensor are electrically connected to the electronic control unit. An upper end of the tube is connected through a hydraulic circuit by a solenoid pass-stop valve with the mixing evaporator of breathing gases. The solenoid valve is electrically connected with the electronic control unit. The tube is made of an infrared transmitting material An infrared optolectronic sensor connected with the electronic control unit and fixed in relation to the tube body at the level exceeding the liquid yield level into the mixing evaporator is provided from the side of the tube.

EFFECT: using the invention enables more accurate adjustment of the liquid anaesthetic vapour concentration.
