ANAESTHETIC EVAPORATOR Russian patent published in 2013 - IPC A61M16/18 

FIELD: medicine.

SUBSTANCE: invention relates to medical equipment. An evaporator comprises a chamber 1 with the number of vertical evaporating elements 2,3 made of a capillary active material and an in-built horizontal gas distributor in the form of a rotary tubular slide valve 5 with a concentration scale 6, clearances 7,8 opposite inlets 9 and outlets 10 of the chamber and an in-built bellow valve 11 with longitudinally movable cowl 12 on the input 13 and a cone 14 on the output 15. The evaporator is provided with an additional slide valve 16 in the form of a convergent tube 17 represented in the conical form and movable longitudinally depending on an angle of rotation of the tubular slide valve 5 and providing the annular gap adjustment between the convergent tube and the cone 14 ensuring stable waterjet-assisted mechanical resistance of the evaporator. The chamber 1 is provided with the inlet 19 and outlet 20 arch boxes with side walls and a front partition coated by the capillary active material from the inside and outside; the boxes are spaced from the body of the tubular slide valve 5 and connected through the end clearances from the inside walls of the chamber 1 with the number of the evaporating elements 2,3.

EFFECT: more stable anaesthetic dosing.
