Portable wireless electrocardiogram, heart sound and breath sound acquisition terminal device

Abstract

The invention relates to a portable wireless electrocardiogram, heart sound and breath sound acquisition terminal device, and the device comprises a heart sound / breath sound sensor, a heart sound and breath sound signal conditioning circuit, an electrocardiogram sensor, an electrocardiogram signal conditioning circuit, an A / D (analog / digital) converter, a CPU (central processing unit) processor, a keyboard, a wireless transmitting / receiving module and an LED (light-emitting diode) indicator lamp, wherein the heart sound / breath sound sensor is connected with the heart sound and breath sound signal conditioning circuit and further connected with the CPU processor through the A / D converter; the electrocardiogram sensor is connected with the electrocardiogram signal conditioning circuit and further connected with the CPU processor through the A / D converter; and the CPU processor can perform wireless transmission of signals through the wireless transmitting / receiving module. The portable wireless electrocardiogram, heart sound and breath sound acquisition terminal device has the characteristics of synchronously acquiring electrocardiogram, heart sound, breath sound and other physiological parameter data of a human body, being capable of providing more intuitive diagnostic data by transmitting the data to a storage display device through the wireless transmitting / receiving module after filtration and signal amplification, giving out rapid diagnostic information for arrhythmia, structural heart diseases, lung diseases and other common diseases.

Description

technical field [0001] The invention relates to a portable wireless electrocardiogram, heart sound and breath sound collection terminal device. technical background [0002] The portable wireless ECG, heart sound and breath sound collection terminal is a convenient medical device for rapid diagnosis of 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, In busy emergency rooms and noisy ambulances, it is almost impossible to effectively diagnose with a traditional stethoscope. Moreover, the heart disease information obtained by simple heart sound auscultation is very limited, and it is impossible to effectively distinguish the types of arrhythmia.

Problems solved by technology

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, In busy emergency rooms and noisy ambulances, it is almost impossible to effectively diagnose with a traditional stethoscope

Moreover, the heart disease information obtained by simple heart sound auscultation is very limited, and it is impossible to effectively distinguish the types of arrhythmia.

At the same time, some arrhythmias are short-lived and sporadic. If the ECG and heart sound information can be collected and stored quickly during the attack, the efficiency of diagnosis and treatment will be greatly improved; at present, there is no portable medical device that can perform heart and breath sound auscultation and ECG detection at the same time. , how to design a heart sound breath sound and electrocardiogram detection equipment that has a reasonable structure and is deeply loved by medical staff is not only an important research topic for scientific researchers, but also one of the imminent tasks for medical equipment manufacturers.
