Electrocardiogram examination device capable of resisting interference

Abstract

The invention discloses an electrocardiogram examination device capable of resisting interference. The electrocardiogram examination device comprises an anti-static shell, and a display screen is installed on the upper surface of the anti-static shell. The electrocardiogram examination device capable of resisting the interference is simple in structure, static electricity and electromagnetic radiation of an external environment are shielded through the anti-static shell and an electromagnetic shielding hood, an independent storage battery is arranged in the device, frequency points with specific frequencies or frequencies of the points except the frequency points in a power line are effectively filtered out through a power filter, a power signal with the specific frequencies is obtained, the stability of output voltage is guaranteed through a voltage stabilizer, signal interference caused by instable output of the storage battery is avoided, a photoelectric coupler can greatly improvethe capability of preventing the common-mode interference of the system, a low-pass filter allows signals lower than a cut-off frequency to pass through, but the signals higher than the cut-off frequency cannot pass through, and high-frequency signals collected when a patient waggles are filtered out, so that the detection result is more accurate.

Description

technical field [0001] The invention relates to the technical field of electrocardiogram inspection, in particular to an anti-interference electrocardiogram inspection device. Background technique [0002] The existing electrocardiogram inspection components involve multiple probe bodies, so the circuit is complicated, the wiring is complicated, and the anti-interference performance is poor. Since the detected bioelectricity is relatively weak, various factors such as external electromagnetic radiation and static electricity will affect the signal. The transmission and processing have an impact, which leads to a decrease in the reliability of the test results and affects the medical staff's analysis of the patient's condition, which is extremely inconvenient to use. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing defects, provide an anti-interference electrocardiogram inspection device, effectively ...
