Design And Research On ECG Monitoring Equipment Based On Ergonomics

With the development of social health undertakings, ECG widely used in hospitals in the CCU and ICU specialist care unit and other places. With the improvement of scientific and technological level of society, the current level of technology and hardware design of the monitor is quite developed, but there are some gaps in the effectiveness and efficiency of the use of aspects of the man-machine environment.After the field investigation and found the following problems, such as prone to dizziness and other symptoms close observation data; display and operating logic is not strong; the key identification prompt is not strong, prone to error condition during operation; monitor the model range, digital display size and position are different, take a longer time to adapt to the new models replace; inadequate length of the lead wire, affecting the stability monitoring function;and now with mobile vehicle designed to adjust the monitor height can not meet the needs of users; monitor The operating space is too small, there are limitations and many other issues. The research to solve these practical problems as a starting point, the use of research principles and methods of ergonomics analysis monitors human, machine and environment systems.I. research questionnaire survey, user interviews, inspections, investigations, field observation and actual measurements and mathematical statistics, summed to obtain monitor the various needs of users in contact with the monitor process. Including visceral level, the material volume of the demand for color instrument; height behavior on the angle of the display interface levels observed, the demand manipulation interface design as well as to reflect the level of demand for the operating environment and so on.II. The subject of the study of existing problems. From the point of view of the man-machine user(operator monitors the medical staff, the patients were monitored) specific characteristics, such as mental, physical, mental and operational action carried out a detailed analysis. Combined with the user in the field of survey information on user demand factors were analyzed.III. Combined with ergonomics theory monitors human, machine and environmental impacts are discussed mutual relations. Proposed the concept of monitor use of the system, and through man-machine analysis, and uses the body size, the size of the monitor and other design discussions were completed to improve the design of theoretical research.IV. Analysis of the medical staff for the operation of the monitor, in conjunction with environmental analysis and design points. The use of coordination, convenience of principles proposed monitor operating space improve the new program. And then summed up the designideas and methods of use of environmental monitors.V. To make the subject of research can meet the needs of the medical staff. Researchers six provinces in the country selected sample of 20-55 year old men and women 907 people, standing body dimensions were measured, and the measured data collation, linear checks to ensure the authenticity of the data. Human complement our existing database size.Six of the monitor by the user and the equipment and man-machine environment analysis,monitors the design should pay attention to safety, comfort, consistency, easy to take and so on principle; operating environment design should pay attention to coordination, regularity,interactive principles. Improve the design and make the monitor device.By studying this subject to the conclusion, based on the study design can be extended to other medical products go towards designing more full professional characteristics of user-friendly products.
