A portable ECG and sleep breathing monitoring system

Abstract

The invention discloses a portable electrocardio and sleep respiration monitoring system, belongs to the field of medical equipment, and mainly solves the problems of long-term, continuous, real-time and remote monitoring in home monitoring. In the system, an integrated electrode and a sensor circuit are integrated through a biological micro-electronics mechanical technology, electrode wires are eliminated, and electrophysiological signal non-contact detection is achieved. The sensor circuit takes a variable capacitance diode as an electrophysiological signal sensor and a coil as a respiration signal sensor and is provided with an instrument amplifying circuit function. Detection signals are transmitted to a phase detection and reading circuit through resonant coupling wireless transmission after modulation. The phase detection and reading circuit demodulates the received modulated signals in a phase detection mode to separate electrocardio from respiratory wave signals. A signal acquisition, storage and transmission module acquires and stores the electrocardio and respiratory signals under the control of a main controller and transmits the signals to an information processing platform in a general packet radio service (GRPS) or USB mode so as to monitor the electrocardio and sleep respiration.

Description

technical field [0001] The invention relates to a portable electrocardiogram and sleep breathing monitoring system, which is suitable for the field of medical equipment. Background technique [0002] Home ECG monitoring requires long-term, continuous, real-time, and remote monitoring. Although there are many portable ECG products on the market, it is difficult to fulfill the above requirements perfectly at the same time. Portable ECG monitors can be divided into sticky electrodes and non-sticky electrodes according to the electrodes used. Non-adhesive electrodes do not use conductive paste, and the metal electrodes are directly attached to the human skin for measurement, and then transmitted to the hospital monitoring center through a wired telephone. However, the measurement time is short, and it is only measured for a short time when the patient feels unwell, generally about tens of seconds. The other type is stick-on electrodes. The ECG electrodes are fixed on the skin...

Problems solved by technology

The other type is stick-on electrodes. The ECG electrodes are fixed on the skin and sampled with conductive paste coupling, which can continuously record ECG signals and have a large amount of information. However, stick-on electrodes are rarely used for more than 4 days, and the skin will Redness, itching, unbearable, at the same time, the conductive paste dries and the electrode surface is corroded, and the electrode impedance will change with time, so it is not suitable for long-term continuous monitoring

The monitoring of ECG by these two types of equipment is short-term. If arrhythmia does not occur within the limited time, the probability of being discovered is very low.
