DEVICE FOR PERCUTANEOUS APPLICATION OF CARBON DIOXIDE AND METHOD OF OPERATION OF SAID DEVICE Russian patent published in 2024 - IPC A61H33/14 A61M35/00 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medical equipment, namely to a device for percutaneous application of CO₂ for the purpose of treating chronic wounds or neuropathy, use of the device and a method of operating the device. Device comprises therapeutic chamber, part of which is configured to receive part of patient's body for supply of CO₂. Device includes inlet/outlet tube connecting chamber with CO₂ distribution system. Inlet/outlet tube is connected to the chamber by means of a valve. Device has CO₂ distribution system containing body, where the first tube with the first valve for supplying CO₂ from the cylinder or reservoir is installed, the second tube with the second valve for air suction from the chamber. First and second tubes are integrated into an inlet/outlet tube before the valves. Device has a device for supplying an air flow through said valves and an inlet/outlet pipe and an air flow measuring device for measuring air flow through the valve on the inlet/outlet pipe. Device includes a reservoir for storage of CO₂ under pressure from 1 to 5 bar, connected to the second tube. Device contains an outlet tube for exhaust of waste air from the chamber through the wall to the external environment of the room, where the device is installed, and a cylinder for storage of CO₂, which is connected to CO₂ distribution system or to the reservoir. Use of the device is intended for therapy. In the case of flexible chambers, the method of operation of the device involves first attachment of the chamber to the inlet/outlet tube by means of a valve or a gate valve. Method involves a step of placing a part of the patient's body into a chamber and sealing the chamber. Method includes a step of pumping out all the air from the chamber with the first valve by means of a fan and directing all the pumped out air outside the room where the device is used. Method includes a step of directing CO₂ from a cylinder into CO₂ distribution system or a reservoir, thereby expanding CO₂ in the reservoir to reduce the pressure and increase the temperature of CO₂. Method includes a step of closing the first valve and opening the second valve for supplying air into the chamber, and/or opening the third valve for supplying 100% CO₂ into the chamber. Method includes a step after introduction of CO₂, suction of air with CO₂ from the chamber through an outlet tube and output outside the room where the device is installed.

EFFECT: improved blood circulation, as well as nutritional perfusion of the treated area.
