DEVICE FOR MEASURING ARTIFICIAL LUNG VENTILATION APPARATUS CHARACTERISTICS IN AUTOMATED WAY Russian patent published in 2003 - IPC

FIELD: medical engineering. SUBSTANCE: device has lung model in particular pneumatic one. One inlet of the model is connected to an opening for attaching patient to artificial lung ventilation apparatus via T-joint. The other inlet is connected to unit for measuring respiratory volume. The unit for measuring respiratory volume has pressure converter, amplifier, analog-to-digital converter multipositional output of which is connected to the second multipositional input of unit for calculating respiratory volume the first multipositional input of which is connected to multipositional output of control unit. The control unit has unit for making parameter input and a unit for processing control signals. Multipositional output of calculator is connected to multipositional input of unit for making artificial lung ventilation apparatus parameter output that has unit for processing output parameters and data display unit. EFFECT: high accuracy of measurements; larger number of measurable parameters. 2 cl, 3 dwg
