ARTIFICIAL LUNG VENTILATION APPARATUS Russian patent published in 2020 - IPC A61H31/02 A61M16/00 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to an artificial lung ventilation (ALV) apparatus. Apparatus comprises a first set provided with a flexible compressible bag, a valve unit and a respiratory tube, as well as an electromechanical linear drive with programmed control. Apparatus is further provided with a second set provided with a flexible compressible bag and an adapter, with a measuring cup function, fixed between spring-loaded swivel holders on a removable magnetic pad of the pressure plate provided with linear bearings, with possibility of vertical movement along parallel located guides by means of rod, connected to electric motor of electromechanical linear drive, connected to adjusting screw, installed in housing, which consists of two U-shaped detachable parts with detachable side walls. Second set is located perpendicular to axis of movement of linear drive, parallel to first set, fixed by means of fixing belt on detachable magnetic plate of lower plate – base connected with guides. Bag of the first set is connected through a unit of nonreversible breathing valve and a pressure limiting valve, a respiratory tube to a face mask or an endotracheal tube of the patient. Bag of second set is parallel connected by adapter via tee to pressure gage, pressure sensor and to electromagnetic pneumatic valve, which are connected to electronic control unit, also connected to contactless limit switches, lower, upper, and electric motor.

EFFECT: technical result achieved by the invention consists in broader functional capabilities of the ALV apparatus, providing ALV pressure monitoring during each cycle and enabling adjustment of ALV cycle parameters.
