DEVICE FOR CREATING HYPOXIC HYPERCAPNIA Russian patent published in 2024 - IPC A61M16/00 A61M16/10 A61M16/20 A63B23/18 

FIELD: medicine.

SUBSTANCE: invention relates to medical equipment, namely to a device for creating hypoxic hypercapnia. Device comprises a detachable breathing tube, a cylindrical housing, with a connection space capacity having a fairing and a cover with a diaphragm installed on top of the cylindrical housing and configured to adjust the volume of the connection space by switching off part of the cells from the ventilation. Device is configured to discharge exhaled air into the atmosphere through the hollow through cylindrical channel and cells and inhale air enriched with carbon dioxide and oxygen-poor air from the cells and the hollow through cylindrical channel. In the device, the capacity of the connecting space is formed around a hollow through cylindrical channel extending from the removable breathing tube, and is divided into cells, the volume of each of which corresponds to the volume of the connecting space. Cells are made in the form of helically twisted channels, where each helically twisted channel forms one cell and is twisted in a spiral with an inclination to the plane of the base of the cylinder so that the inlet and outlet of each channel are located opposite each other along the vertical. Cylindrical housing is made in the form of a module in which the lower part is formed so that it can be docked with the upper part of the same module. Diaphragm consists of an upper flap made in the form of a flat circle with a central hole, two cutouts in the form of sectors and a thrust projection, middle gate, consisting of a cylinder, the upper part of which is formed by a flat circle with a central hole, two cutouts in the form of sectors and a thrust protrusion located on the side surface of the cylinder, which is cut to the half of the base in the part which do not cover the cutouts of the sectors, lower gate consists of a rim formed around the central hollow cylinder and connected to it by plate stiffening ribs, where part of the rim has a side surface cut by half the diameter.

EFFECT: increased length of dead space of airways, possibility to reduce load level, as well as possibility to increase load during training and increase its effectiveness by changing CO₂ concentration inside the device.
