Embodiment Construction

[0040] Such as figure 1 A twelve-lead electrocardiographic signal synchronous acquisition module shown is composed of the following circuits:

[0041] 1. Hardware Circuit Composition

[0042] 1.1 ECG signal input part

[0043] ECG signal input part is composed of LM324 and R101-R118.

[0044] ECG signals come from the body surface. Electrocardiographic signals are obtained through nine surface electrodes of the left foot LF, left hand L, right hand R, and V1, V2, V3, V4, V5, and V6. The right foot electrode RF is connected to the ground terminal of the entire acquisition module.

[0045] The six electrode signals of V1 ~ V6 are respectively connected to the differential amplification part through six 10K resistors of R106 ~ R101.

[0046] The three electrode signals of the left foot LF, the left hand L and the right hand R are respectively connected to the non-inverting input terminals of the three operational amplifiers of the LM324; the inverting input terminals of each...

Abstract

A twelve-lead electrocardiosignal synchronous acquisition module belongs to the technical field of medical devices and solves the problems that the existing twelve-lead electrocardiogram adopts wired measurement, so the detection is inconvenient and the measuring equipment is high in cost. The twelve-lead electrocardiosignal synchronous acquisition module comprises a body surface electrode, an electrocardiosignal input circuit, a differential amplification circuit, a filter circuit, a lead selection circuit, a signal amplification circuit, a analog-digital conversion circuit, a single chip computer and a level switching circuit all connected in sequence. When in use, the twelve-lead electrocardiosignal synchronous acquisition module disclosed by the invention is connected with an embedded WIFI module, and then connected with a computer in a wireless manner, so a low-cost domestic twelve-lead electrocardiogram wireless measuring system is established, domestic wireless measurement of the electrocardiogram is realized, the electrocardiogram detection is convenient, and the detecting equipment is low in cost.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, in particular to an electrocardiographic signal acquisition device. Background technique [0002] Twelve-lead ECG detection is an important means of heart function and heart disease diagnosis. The existing 12-lead electrocardiogram adopts wired measurement, which makes the detection inconvenient and the price of the measuring equipment is high, so that the measurement of the 12-lead electrocardiogram can only be completed in the hospital. Contents of the invention [0003] In order to solve the problem that the existing twelve-lead electrocardiogram adopts wired measurement, the detection is inconvenient and the cost of the measurement equipment is high, the present invention provides a twelve-lead electrocardiogram synchronous acquisition module, and its technical scheme is as follows: [0004] A twelve-lead ECG signal synchronous acquisition module: [0005] It includes sequential...
