DEVICE NCPAP WITH FLOW DIVISION Russian patent published in 2016 - IPC A61M16/00 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medical equipment. Nasal continuous positive airway pressure device includes an inlet, configured for receiving a single gas jet flow and connected with a high-pressure chamber and a flow splitter configured for proportionally splitting said gas jet flow into two channels for the both nares. Flow divider is used for proportional separation of gas jet flow along curved edge transition to the first channel and the second channel. Each channel is connected to the first and the second port, respectively. Flow direction divider is further configured to supply separated single gas jet flow for each of both nares in compliance with one or more anatomy of nares and/or resistance to flow path of at least one of two nares. Flow direction divider is communicated by the fluid medium with inlet by means of the nozzle. Outlet port is communicated with the first channel and the second channel and is configured to collect excess flow intended for inhalation, and to deflect, if necessary, flow of exhalation. Separated single gas jet flow is controlled in accordance with resistance to flow path, at least into one of two nares. Method for separation of gas jet flow is disclosed.

EFFECT: inventions solve a problem of improving ease of use at maintenance of continuous positive airway pressure of infants.
