Goal
  • The objectives of the discipline are to familiarize students with the primary devices for taking medical and biological information about the main manifestations of life processes: mechanical, biochemical, etc.; familiarization with various classes of biological information sensors (DBI), the physical principles of operation of these devices, their designs and features of application in biomedical practice and research.
Objective
  • the physical nature of biomedical signals; - sensor (from the English sensor) is a concept in control systems, a primary converter, an element of a measuring, signaling, regulating or controlling device of a system that converts a controlled quantity into a signal convenient for use; - classification of sensors by type of output quantities, -classification by measured parameter; -sensors blood pressure; -contact, contactless.
Learning outcome: knowledge and understanding
  • To know: - features of biological objects as objects of research; - the main types and design options of IP and electrodes; - the basic physical principles underlying the work of the IP; - metrological characteristics, methods and exemplary means for testing, checking and calibration of IP and E; - the main problems that arise when coordinating the IP with the measuring circuit, and the ways of such coordination; - methods of analysis of input circuits of biomedical equipment.
Learning outcome: applying knowledge and understanding
  • Be able to: - in accordance with the methods and tasks of conducting biomedical research, select the types and variants of IP and electrode designs that are most necessary in terms of metrological characteristics, structural and electrical parameters; - be well oriented when carrying out preventive, calibration and repair measures with IP and electrodes used as part of medical and biological equipment; - calculate the main metrological characteristics of IP and electrodes and elements of electronic matching circuits. Own: - skills in choosing the type and variant of IP and E structures in accordance with the methods and tasks of conducting biomedical research satisfying metrological characteristics, structural and electrical parameters; - calculation and design skills of measuring transducers and biomedical information retrieval tools; - skills of constructing means of coupling biomedical equipment with a biological object (patient). - skills in assessing the basic metrological characteristics of IP and E and elements of electronic matching circuits.
Learning outcome: formation of judgments
  • Formulate the goals and objectives of research and medical equipment maintenance practices, develop and analyze problem solving options, and predict the consequences
Learning outcome: communicative abilities
  • Be proficient in English, be able to work in an international environment, organize linguistic support for international conferences, symposiums, forums;
Learning outcome: learning skills or learning abilities
  • To study and analyze scientific and technical information, technical indicators and research results, to summarize and systematize them;
Teaching methods

Interactive learning and multimedia technologies Multimedia presentations and videos: The use of video lectures, animations, and simulations to explain complex technical processes, such as the operation of medical devices or biosignals. Virtual laboratories: create simulations of working with medical devices, which allows students to experiment with devices and systems without the need for real equipment.

Assessment of the student's knowledge

Teacher oversees various tasks related to ongoing assessment and determines students' current performance twice during each academic period. Ratings 1 and 2 are formulated based on the outcomes of this ongoing assessment. The student's learning achievements are assessed using a 100-point scale, and the final grades P1 and P2 are calculated as the average of their ongoing performance evaluations. The teacher evaluates the student's work throughout the academic period in alignment with the assignment submission schedule for the discipline. The assessment system may incorporate a mix of written and oral, group and individual formats.

Evaluation form

The student's final grade in the course is calculated on a 100 point grading scale, it includes:

  • 40% of the examination result;
  • 60% of current control result.

The final grade is calculated by the formula:

FG = 0,6 MT1+MT2 +0,4E
2

 

Where Midterm 1, Midterm 2are digital equivalents of the grades of Midterm 1 and 2;

E is a digital equivalent of the exam grade.

Final alphabetical grade and its equivalent in points:

The letter grading system for students' academic achievements, corresponding to the numerical equivalent on a four-point scale:

Alphabetical grade Numerical value Points (%) Traditional grade
A 4.0 95-100 Excellent
A- 3.67 90-94
B+ 3.33 85-89 Good
