Micro signal detection device integrating collecting and filtering

Abstract

The invention discloses a micro signal detection device integrating collecting and filtering. The micro signal detection device comprises a sensing circuit and a readout circuit, wherein the sensing circuit and the readout circuit carry out information transfer through wireless mutual inductance coupling; the readout circuit comprises a sine wave signal generator, a lag beta phase-shifting circuit, a first voltage follower and a first waveform transformation circuit which are sequentially connected; the sine wave signal generator, a lead beta phase-shifting circuit, a second voltage follower, an inductive coil circuit and a second waveform transformation circuit are sequentially connected; the first waveform transformation circuit and the second waveform transformation circuit are connected with a phase discriminating circuit separately; and the phase discriminating circuit, a low-pass filter circuit and an amplifying circuit are sequentially connected. The condition in the prior art that an ECG collecting device is directly connected to the skin of a human body through an electrode and a wire is avoided, so that the free motion range of a patient is expanded, meanwhile, the comfort is improved and the accuracy and the instantaneity of an electrocardiosignal are improved.

Description

technical field [0001] The invention relates to biological signal detection, in particular to a micro-signal detection device integrating collection and filtering. Background technique [0002] In recent years, the prevention and treatment of cardiovascular diseases has become a key content of personal health care. Cardiovascular disease is a very common multiple disease, which is unpredictable, sudden, and has a high risk of disability and death. Generally, conventional ECG acquisition and monitoring equipment is bulky and inconvenient to carry, and cannot provide real-time and continuous monitoring of patients with cardiovascular diseases, making cardiovascular diseases a huge killer that is easily overlooked by people. Currently, with With the rapid development of medical electronic science and technology, the research on ECG monitoring equipment is also developing towards the trend of miniaturization, low energy consumption and multi-function. At present, most of these...
