Principles And Functions Of Portable ECG Monitor

Wiki Article

Portable ECG monitor is an automatic, intelligent and precise instrument, which is a new type of portable digital medical testing equipment mainly used to monitor the dynamic parameters of the patient's physique.
working principle




The ECG monitor is mainly composed of sensor circuit signal acquisition, signal processing system, recording device, control system, alarm device and display output circuit, etc. It can accurately measure human cardiac electrical activity, respiration , blood pressure and pulse and other vital parameters. Provide effective basis for medical staff diagnosis, treatment, nursing and rescue.

Its working principle is that in the process of operation, the cardiac electrical activity is transmitted to the processor through the ECG lead wire, the blood pressure is converted into an electrical signal into the processor through the pressure sensor, and the respiratory activity is caused by the change of thoracic resistance caused by exhalation and inhalation. The ECG leads and ECG activity are simultaneously transmitted to the processor. The processor amplifies the electrical signal from the patient, and processes it with the help of the microcomputer inside the system to form a waveform or digital signal, which is then analyzed to a certain extent. The result is given an alarm, and finally the processed information and results are output



The main function



Abnormal changes such as chest pain, chest tightness, dyspnea, heartbeat, etc. can be recorded at any time, which is convenient for medical treatment. In the past, it often took a long time from the onset of the disease to the hospital visit. After the symptoms disappeared, the test was likely to fail to find the cause, which delayed the best time for diagnosis. Using a portable ECG monitor, when symptoms occur, it only needs to be close to the chest for 30 seconds to record the abnormal situation, and the measured ECG can be provided to the doctor when visiting the doctor, which is very beneficial to assist the doctor and treatment.

24-hour dynamic recording, record the heart abnormal moment in time. As an effective extension and supplement of the hospital's conventional equipment, the portable ECG monitor helps users to record the long-term activity of the heart completely, and any cardiac discomfort will be monitored in time. When the disease occurs, the complete data recorded by the device and the special analysis software will be very suitable for doctors to initially screen the disease.

Light bedside monitoring, intimate whole-process care. In addition to hospitalization, cardiac patients need appropriate ECG monitoring equipment to complete real-time monitoring. The portable ECG monitor, with its simple and accurate single-lead monitoring and clear color screen display, helps heart patients to know their heart conditions at any time and avoid accidents.

With the increasing development of wireless communication technology and network technology, major breakthroughs have been made in ECG remote transmission technology. At the beginning of this century, the "all-in-one" cardiac mobile phone appeared, which integrates the ECG acquisition and processing unit and the transmitting device into a special mobile phone. Inside, by hand-held, the bottom electrode of the mobile phone contacts the chest wall to form a loop to collect ECG signals, and then the ECG information is sent to the data processing center through the mobile communication network.



For people



As a brand-new heart detection and self-monitoring device, the portable monitor can record transient cardiac abnormalities anytime and anywhere, and is widely used in sub-healthy people, especially for coronary heart disease , hypertension , cardiovascular disease , diabetes patients, postoperative patients and other people. Health monitoring.



Features



Portable ECG monitors are easy to operate. Usually hospital monitors require professionals to operate, the process is more complicated, and the size of the machine is also large.

It is easy to carry and can be continuously measured for 24 hours without any problems, so as to capture the abnormal waveform of the heart in time. Due to the irregularity of heart disease, timely detection of the disease can achieve the effect of early prevention and early diagnosis and treatment.

Ultra low power consumption. Even when the patient is away from home, they can keep abreast of their heart conditions at any time, and in the case of battery power, the low power consumption of the system makes the standby time longer.

The portable ECG monitor can be used as a medical Internet of Things terminal instrument to collect human physiological signals and quickly transmit them to the back-end service platform through modern communication technology.



Precautions




The monitoring environment is safe, it is required to be placed in a fixed position, and the moving environment is avoided as much as possible. The temperature is 5 to 40 °C, the relative humidity does not exceed 80%, and a space of at least 5 cm is required. The air circulation structure is the most important. Cell phones are not placed. Avoid strong electromagnetic interference from wireless devices and other devices to avoid monitoring interference of waveforms and values. Power cords and sockets are tightly connected, and all cables are properly connected.

Correctly set the function options of monitoring ECG and cable type and parameters, such as adjusting the amplitude and speed of parameters, observing the filter function of the wave, eliminating electromagnetic interference, EMG display alarm volume through reasonable channels, screen brightness and clock need to be accurate, so that Monitor the ECG monitor for optimal condition.

Degrease, clean and dry the skin in contact with the electrodes to avoid interference with resistance and interference with ECG waveforms in EMG monitoring. Cable clips should be clean and smooth.

Monitor blood pressure patients to choose the correct type, usually "Adult, Pediatric, Neonatal" option. Continuous blood pressure monitoring, changing the monitoring place every 6 to 8 hours.

To detect blood oxygen saturation, pay attention to avoid and remove nail polish, and replace the measurement site every 1 to 2 hours to prevent swelling caused by blood circulation disorders.

Regularly maintain the daily cleaning of the surface of the host. After removing the dirt, wipe it with 70% alcohol in time, and then dry it. The circular depressions with large bends in the leads should be clean and easy to use. The professional maintenance staff of the filter maintains the filter every month, disassembles the casing machine every year, and cleans the dust.
