Holter Ecg Cable And Leads has many measures to ensure the accuracy of ECG signal acquisition at different frequencies.
First of all, in terms of material selection, the conductor materials of cables and wires need to have good conductivity, such as copper and other metals, which can efficiently conduct ECG signals. For insulating materials, they must have low dielectric constants and low loss factors to reduce the attenuation and distortion of signals during transmission. For example, the use of high-quality insulating materials such as polyvinyl chloride can effectively prevent the influence of external electromagnetic interference on ECG signals, thereby ensuring the accurate transmission of signals of different frequencies.
Secondly, the design structure of cables and wires is also crucial. Reasonable wire diameter and shielding structure can improve the quality of signals. Thicker wire diameter can reduce resistance and reduce signal loss during transmission, especially for low-frequency ECG signals. The design of the shielding layer, such as the use of metal braided mesh or aluminum foil shielding, can block external electromagnetic interference, such as surrounding electronic equipment, wireless signals, etc. This ensures that ECG signals, both high-frequency and low-frequency, can be accurately transmitted from the patient's body to the recording device even in a complex electromagnetic environment.
Furthermore, the stability of the connection is also the key to ensuring the accuracy of the acquisition. The connection between the cables and wires and the electrodes and the recording device must be firm and reliable. A good connection method, such as the use of high-quality plugs and sockets, can ensure that the signal will not be interrupted or have poor contact at the connection. For ECG signals of different frequencies, accurate connections can avoid signal reflection and attenuation, so that the details of high-frequency signals and the overall shape of low-frequency signals can be accurately collected.
In addition, during the production process, strict quality inspection and calibration are also carried out. By simulating ECG signals of different frequencies, the transmission performance of cables and wires is tested, and their parameters are adjusted to achieve the best acquisition effect. Only in this way can Holter Ecg Cable And Leads accurately collect ECG signals of different frequencies and provide doctors with reliable diagnostic basis.
