| dc.description.abstract | Breathing air volume and rate of a particular person is a key aspect in medical diagnosis.
The present equipments used by the contemporary Bio medical technology can only be used when
the person is in a good condition. However air volume of unconscious or sleeping patients can't be
calculated. The lung capacity may differ from person to person due day to day activities and other
habits. This can.cause a change in the structure of the lungs and lung capacity.
Proposed breathing air volume measuring equipment is made of a plastic mask, which does
not disturb the patient whether he is awake or sleeping. The fan which is fixed on to this mask rotates
to side when the patients inhale and other way when he exhales. There's a coil fixed to the fan and
magnets fixed in to the mask by the side of the coil. According to the speed of the rotation a forward
and backward current will be created and this current is amplified and analyzed by the computer,
which is previously calibrated to the related air volume. This will be monitored in the computer and
it would be easier for the doctors to identify the illness of a patient according to the breathing air
volume.
Chest movements measuring equipment is made of piezo electric strings, and when the
chest stretches the piezo electric string will induce a current and this will be measured and analyzed
by the computer with previously calibrated values of a healthy person. This device measures both
upper chest and lower chest movements, for the doctors to easily examine the patient. | en_US |
