Description
Technical Field
The utility model relates to a measuring equipment field especially relates to a digit electrocardio electrograph data acquisition equipment.
Background
Digital electrocardiographs are instruments used to record and display physiological electrical signals generated during cardiac activity.
The digital electrocardiograph uses ECG electrode to extract physiological electric signal from human body, and the physiological electric signal is fed into the prepositive amplification and filtering circuit by means of lead input network and lead selector, then fed into control portion after A/D conversion, and fed into recorder and display after digital processing, filtering and conversion so as to record and display electrocardiographic waveform.
The conventional electrocardiographic examination is the simplest, effective and safe noninvasive detection for clinically and primarily diagnosing cardiovascular system diseases, has great significance for diagnosing the illness state of patients, and is widely applied to various medical institutions. Metrological verification aiming at digital electrocardiographic paper is always a reserved project of national mandatory verification work. Whether the metering performance is accurate or not is important.
In the metrological verification work of the digital electrocardiogram machine, the original data are all required to be output and judged to be qualified or not. The amplitude and length of the signal waveform collected by the digital electrocardiograph need to be measured manually in the verification process. In the process of manually reading data and studying and judging, the data volume is large, the influence of human factors on the measurement result is large, and the weight of subjective factors of a checker is large.
The metrological verification process of the current digital electrocardiogram machine is characterized in that related mechanism metrological verification personnel carry out metrological verification according to verification rules, in the verification process, the digital electrocardiogram machine collects, amplifies and converts physiological electric signals and then outputs the physiological electric signals, a printing part prints electrocardiogram waveforms on matched electrocardiogram paper, then the verification personnel manually reads the electrocardiogram waveform data by using a steel ruler, a divider and a magnifier, and whether verification results are qualified is measured, calculated, researched and judged by combining standard waveform parameters of ECG simulation signals.
The prior art solution has the following problems:
the influence of subjective factors of manually read data is large, the workload is high, and the working efficiency is low.
Firstly, data is manually read, subjective factors exist in data reading habits and standards of each person, and judgment standards are not uniform, so that accuracy and consistency of metrological verification results are affected. Secondly, the number of manual measurement data acquisition points is large, dozens of data are measured in sequence by using a magnifying lens, and the visual ability of human eyes is greatly consumed. When a plurality of groups of data come down, the vision loss of the detection personnel is large, the reading capability is greatly reduced, and the reading precision can be distorted. In order to ensure that the metering data is accurate and reliable, the verification work progress needs to be properly slowed down, and the vision reserve of verification personnel is recovered, so that the verification work progress is influenced. With the improvement of the living standard of people, people pay more and more attention to the health state of the people, and the updating and configuration speed of medical institution equipment is far greater than the matching speed of metrological verification personnel. The medical institution meters have large holding capacity, are all in the same department, are in a full-load operation state, and cannot bear a working state that the working progress is slowed down. If verification progress is required blindly, the accuracy of verification data is sacrificed, which cannot be tolerated by metrological verification work. Ultimately, the metrological verification work efficiency is low. If can adopt automatic calibrating installation to cooperate the staff work of calibrating, liberate certain manpower consumption, will satisfy medical institution's measurement technical appeal faster better, guarantee the increasing of people's standard of living.
