Problems solved by technology
At present, most portable ECG signal collectors on the market use their own supporting display and recording equipment, and one collection terminal can only correspond to one display and recording terminal of the same manufacturer, which not only reduces the portability of the equipment, but also increased production costs

The invention discloses portable electrocardio and heart sound signal collection equipment. The portable electrocardio and heart sound signal collection equipment is characterized in that an electrocardio sensor, an electrocardio signal conditioning circuit, a heart sound sensor and a heart sound signal conditioning circuit are included; the electrocardio sensor is connected with the electrocardio signal conditioning circuit, the heart sound sensor is connected with the heart sound signal conditioning circuit, the electrocardio signal conditioning circuit and the heart sound signal conditioning circuit are connected to an AD converting module in parallel, and the AD converting module is sequentially connected with a single chip microcomputer processing module and a wireless communication module. The equipment can collect electrocardio signals and heart sound signals in real time, the collected electrocardio and heart sound signals are easy to identity and read, and the equipment can be connected with an intelligent terminal in parallel and is low in cost.
Description
technical field [0001] The invention relates to medical instrument technology, in particular to a portable electrocardiogram and heart sound signal collection device. Background technique [0002] ECG signal and heart sound signal are physiological signals generated when the heart muscle is working. The analysis of ECG signal and heart sound signal is two important means and standards for diagnosing heart diseases. For the detection of common heart diseases, especially myocardial infarction and arrhythmia, compared with other diagnostic methods, the ECG signal has the advantages of fast, convenient, simple and practical, cheap and non-invasive. However, for some lesions of the heart tissue itself, it will not be directly reflected in the ECG signal, but it can be reflected in the heart sound signal. The general portable ECG instrument only has the function of collecting ECG, but does not have the function of collecting heart sound. Therefore, a portable ECG and heart sound ...
