Rules for evaluation and completion of the course

Extent and forms of monitored teaching is specified by guarantor’s regulation updated for every academic year.

Aims

The knowledge of students will be extendt to general instruments technique. The next profit will be theoretical and practical dexterity from electrical measurement of electrical and nonelectrical quantity. The part of education is practical experience with measuring instruments and methods for DC and Ac measurement.
The student obtain practical experience with operating of basic instruments in clinical practice, application these instruments to patients and with procedure for evaluation of measured values.

Teacher / Lecturer

Ing. Vratislav Harabiš, Ph.D.

Syllabus

1.Design and testing of basic electronic circuits
2.Measurement of basic electrical quantities (current, voltage, power, frequency, phase shift, impedance, capacitance, inductance)
3.Basic measuring instruments and methods for DC and AC measurements
4.Basic electronic instrument modules (power supplies, filters, amplifiers)
5.Basic electronic instrument modules (comparators, electronic switches, flip circuits)
6.Logic members and circuit principles for implementing combinational functions 

Laboratory exercise

39 hod., compulsory

Teacher / Lecturer

Ing. Vratislav Harabiš, Ph.D.

Syllabus

1. Electrocardiograph – scanning of EKG signal, the basis of evaluation
2. Electromyograph – scanning of signals from groups of muscles ( using surface electrodes) for different isometric load of muscles
3. For the whole group of above devices – effect of transmission characteristics of the device on the resulting shape of signal (the source will be a simulator). Diagnostic significance of the changes. Simulated defects in devices influence the resulting transmission characteristics.
4. Scanning of the electric activity of brain – impact on the behaviour of the patient and on the nature of the signal, evaluation of the shape of the signal
5. The parameters of scanning electrodes.
6. Blood pressure measurement – use of Korotkov sounds and the oscillometric method and their comparison.
7. Pure tone audiometry, speech audiometry
8. Impact of the discrimination factor of the device on the magnitude of interference with the scanned signal by network frequency of 50 Hz. Impact of the transition resistivity of electrodes on the resulting discrimination factor (difference between the theoretical and practical value).
9. Impedance measurement of blood flow
10. Measurement of blood saturation with oxygen. Possible ways of influencing the final result.
