Example Embodiment

[0026] See Figure 1 to Figure 4 , A wearable lung sound detection device, comprising an acoustic-electric conversion sensor 1 and a soft plastic suction cup 3. The acoustic-electric conversion sensor 1 is installed on a lung sound acquisition circuit board 2, and the lung sound acquisition circuit board is installed on a shell In body 6, the front of the acoustic-electric conversion sensor extends out of the housing, enters the inner cavity of a soft plastic suction cup mounted on the housing, and is fixed to the front of the human thoracic cavity by the suction cup, which effectively ensures the collection of lung sound signals At the same time, it avoids the introduction of some environmental interference noise, and realizes the wearable lung sound acquisition device. The cross-sectional area of ​​the entire device is only the size of an electrode sheet, and it is very quick and light to wear and will not cause any restriction to the patient. A clip 4 is fixed on the back o...

Abstract

The invention relates to a wearable lung sound detection device, which comprises an acoustic-electric conversion sensor and a soft plastic suction cup. The front of the sensor extends out of the shell and enters the inner cavity of the soft plastic suction cup installed on the shell. The circuit board of the lung sound collection is equipped with a microprocessor, a lung sound signal processing module, an A/D sampling module and a power supply module. The acoustic-electric conversion sensor is used to transmit the collected lung sound signal to the lung sound signal processing module, and the lung sound signal processing module is used to amplify and filter the collected lung sound signal to the A/D sampling module, and the A/D sampling module The preprocessed lung sound signal is A/D sampled and the sampled digital lung sound signal is saved as an audio file, and the microprocessor communicates with the intelligent terminal through a wireless transmission module. It can accurately collect digitized lung sounds, and realizes a wearable lung sound collection device.

Description

Technical field [0001] The invention relates to the field of lung sound detection, in particular to a wearable lung sound detection device. Background technique [0002] The digital acquisition, analysis, and recognition of lung sound signals have important clinical research value. Traditional stethoscopes and other detection tools have low resolution and narrow frequency response range, and are also affected by the doctor’s experience and ability to distinguish different lung sound patterns. In addition, it is difficult to record and store quantitatively because of the inability to quantitatively measure. It is also impossible to compare the lung sounds objectively and horizontally. It is also difficult to monitor the correlation between lung sounds and other physiological signals for a long time. Digital lung sound acquisition and analysis and recognition methods overcome the limitations of many simple stethoscopes. Not only can the changes of lung sounds be quantified, but the...
