JET APPARATUS FOR ARTIFICIAL LUNG VENTILATION Russian patent published in 2022 - IPC A61H31/00 A61M16/00 

FIELD: medical equipment.

SUBSTANCE: invention relates to medical equipment, namely, to a jet apparatus for artificial lung ventilation. The apparatus comprises two discrete jet elements: a main bistable and an auxiliary monostable jet elements, control and connecting channels. The apparatus is configured to supplying air with a pressure set on the power source and equal to the breathing pressure of the patient, with pressure indicator control, to the main supply channel and through an ejector to the feeding channel of the main bistable jet element, and through the feeding channel to the auxiliary monostable jet element so that the air, through the output channel of the auxiliary monostable jet element, the first connecting channel, and the first adjustable throttle, is supplied to the control channel of the main bistable jet element, switching the main bistable jet element to supply air to the patient through the channel of the patient, controlled by a pressure indicator. The apparatus is designed so that when the lungs of the patient are filled, excess pressure from the patient through the second connecting channel and the second adjustable throttle is supplied to the opposing control channel of the main bistable jet element and switches the main bistable jet element to discharge the air supplied through the main feeding channel into the atmosphere through the outlet of the main bistable jet element into the atmosphere, while suctioning air from the channel of the patient and simultaneously through the second connecting channel and the third adjustable throttle, switching the auxiliary monostable jet element to the output of the auxiliary monostable jet element into the atmosphere, terminating supply from the auxiliary monostable jet element to the control channel of the main bistable jet element. The apparatus is designed so that in the course of emptying the lungs of the patient, the pressure on the control channel of the auxiliary monostable jet element drops and air switches to the output channel of the auxiliary monostable jet element, and again the air is supplied through the output channel of the auxiliary monostable jet element to the control channel of the main bistable jet element, switching the main bistable jet element to supply air to the patient, and the breathing cycle of the patient is repeated.

EFFECT: ensured forced inhalation of the patient in the absence of their inhalation attempt and additional facilitation of exhalation of the patient.
