WAY OF ARTIFICIAL LUNGS VENTILATION AND DEVICE FOR ITS REALISATION Russian patent published in 2009 - IPC A61H31/02 A61M16/12 A61K31/02 A61P23/00 

FIELD: medicine; anesthesiology.

SUBSTANCE: ventilation of the lungs is carried out by means of use of the artificial lungs ventilation apparatus including the rebreathing system, consisting of an endotracheal tube connected with hoses using a connector. Thus the connector has three connecting parts with the channels, two of them are connected to the hoses. Internal surfaces of channels of the hoses are executed with helicoid twisting to the right or to the left and step of a screw line equal π D where π the number peer 3.14, D - diametre of channels of the hoses. One of the connector channels is connected to an endotracheal tube supplied with a helicoid dividing plate which divides the tube channel into two halves and is executed with step of a screw line peer π D. The apparatus also contains a distributing device, switching mechanism, inspiration generator and input of compressed air. Periodic moving of respiratory gas and-or its admixture with anaesthetics between an environment and lungs of the patient is carried out through the rebreathing system. Thus screw counterflow movement of respiratory gas and-or its admixture with anaesthetics to the right or to the left is provided in an artificial inspiration of the patient before supply in the respiratory system of the patient, and also to the fulfilled gas in an endotracheal tube and-or in hoses provide. Respiratory gas with the right direction of rotation is supplied to the patients with normal location of internal organs, and with the left direction of rotation - to the patients with a mirror location of internal organs.

EFFECT: optimum and effective pulmonary ventilation and gas exchange at the expense of reproduction during inspiration of helicoid movement of gas which is the most physiologic and allows reaching alveoluses and small bronchioles.
