Portable wireless electrocardiogram, cardiac sound and breath sound acquisition, display and storage device

Abstract

The invention relates to a portable wireless electrocardiogram, cardiac sound and breath sound acquisition, display and storage device which comprises a cardiac sound/breath sound sensor, a first low-noise amplifier, a second low-noise amplifier, a signal conditioning circuit, an electrocardiogram sensor, a low and high pass filter, an A/D (Analog to Digital) converter, a CPU (Central Processing Unit) processor, a keyboard, a wireless transmitting/receiving module and an LED indicator light, wherein the cardiac sound/breath sound sensor is connected with the signal conditioning circuit through the first low-noise amplifier and then connected with the CUP processor through the A/D converter; the electrocardiogram sensor is connected with the low and high pass filter through the second low-noise amplifier and then connected with the CPU processor through the A/D converter; and the CPU processor is used for carrying out wireless transmission of signals through the wireless transmitting/receiving module. The device has the characteristics of synchronously acquiring physiological parameter data such as electrocardiograms, cardiac sound, breath sound, and the like of a human body and transmitting the data to a display and storage machine in real time through the wireless transmitting/receiving module, displaying and storing or replaying the electrocardiograms and frequency spectrograms of the cardiac sound and the breath sound and playing the cardiac sound and the breath sound, and providing more visual diagnostic data for doctors; and the device can provide quick diagnosis information of common diseases such as arrhythmia, structural heart diseases, lung diseases, and the like.

Description

technical field [0001] The invention relates to a portable wireless electrocardiogram, heart sound, breath sound collection, display and storage device. technical background [0002] Auscultation of heart and breath sounds and electrocardiogram detection are convenient and common methods for diagnosing cardiopulmonary diseases. The traditional stethoscope is small in size and easy to carry and use, but it is often difficult to capture some weak but very important biological sounds, which makes doctors unable to make a timely diagnosis and delays diagnosis and treatment. Especially in harsh environments, such as messy accident scenes, busy emergency rooms and noisy ambulances, it is almost impossible to use traditional stethoscopes for effective diagnosis. However, the existing heart disease information obtained by simply collecting heart sounds and breath sounds with an electronic stethoscope is very limited, and it is impossible to effectively distinguish the types of arrh...

Problems solved by technology

At present, there is no portable medical device that can perform heart sound / breath sound auscultation and ECG detection at the same time. How to design a portable heart sound, breath sound and ECG signal detection device that is reasonable in structure and popular with medical staff is an important task for researchers. The important research topic ahead is also one of the imminent tasks for medical equipment manufacturers
