TRAINING DEVICE FOR PERFORMING RESPIRATORY EXERCISES Russian patent published in 2002 - IPC

FIELD: medical engineering. SUBSTANCE: device has respiratory tube connected to respiratory chambers partially filled with liquid through valve box. Each respiratory chamber is arranged on the bottom of neighboring reservoir communicating to atmosphere through an opening or gap in the cover. The lower portion of the lateral surface has holes arranged in chess-board order in 2-3 rows, diameters of the holes becoming smaller when moving from the upper to the lower row from 0.5 to 0.2 mm, their total area being equal to the respiratory tube cross-section area and 10- 15% less than outlet opening area on the external reservoir cover. The valve box has air chamber of variable volume. EFFECT: improved metabolism and regulation processes; increased organism stability to physical loading; reduced negative consequences of acute and chronic stress conditions. 6 cl, 2 dwg
