DEVICE FOR EVALUATION OF THE FUNCTIONAL STATE OF RESPIRATORY MUSCLE PATIENT

摘要

The invention relates to medical equipment, namely to the devices for determining the functional state of the patient's respiratory muscles. The technical result consists in increasing the completeness of the information obtained due to more accurate measurement of inspiratory pressure. The device includes a mouthpiece, valve box with inspiratory and expiratory valve and pressure transducer into a digital signal that is connected to a personal computer. The novelty of the utility model is the presence of the solenoid valve mounted on the inlet duct inspiratory and connected to the control unit, whose input in turn is coupled to an output computer provided with a program of the signal after a certain time interval (ms) depending on the phase of the respiratory cycle. In turn, the computer program provided functional state index calculation iTT inspiratory muscles by the _{formula: iTT = P 0,1 / MIP ×} Ti / Tt; iTT comparison with the normal value iTT _n and forming an opinion on the state of the respiratory muscles on the computer screen.
