HYPERBARIC SYSTEM Russian patent published in 1995 - IPC

FIELD: medical engineering. SUBSTANCE: device has a hyperbaric chamber with a cavity for a patient to be placed in and a life support device having a gas supply main line and at least one local hyperbaric chamber with a cavity for extremity to be placed in and a gas supply main line provided with valves to increase or reduce pressure. The local hyperbaric chamber is in the cavity of the hyperbaric chamber receiving a patient communicating with the local hyperbaric chamber cavity through a main line having valve for gas to bypass between the cavities. Device for measuring pressure difference of alternating sign is additionally mounted between the cavity of the hyperbaric chamber receiving patient and the local hyperbaric chamber cavity. Two differential manometers may be used for this purpose when connected with each other by means of different inlet gas supply channels forming in this way devices for measuring excessive and lowered vacuum pressure in the local hyperbaric chamber cavity when compared to that in hyperbaric chamber cavity for receiving patient, respectively. Each of the differential manometers may be provided with an electric output connected through the control system to the valves increasing and reducing gas pressure in the local hyperbaric chamber cavity and gas bypass between the latter and hyperbaric chamber cavity for receiving patient. Controllable throttle valve is mountable sequentially with each of the valves reducing, increasing and bypassing gas pressure in the corresponding pipe line, the valve reducing gas pressure in local hyperbaric chamber cavity is connectable with a recovery unit, for example, with a tank. EFFECT: enhanced reliability in controlling the operating mode of pulsing hyperbaric therapy system; enhanced accuracy in adjusting pressure pulses; higher safety of a patient under treatment in case of emergency decompression. 6 cl, 3 dwg
