Problems solved by technology

When recording lung sound, the stethoscope must be accurately placed between the ribs at a specific position, and it is difficult to obtain a good sound receiving position in operation
Moreover, continuous monitoring of lung sounds for follow-up tracking and analysis is very necessary for respiratory intensive care units, but currently there is no physiological monitor capable of continuously recording lung sounds

Embodiment Construction

[0031] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention are listed below and described in detail in conjunction with the accompanying drawings.

[0032] figure 1 is a schematic diagram of a lung sound monitoring device 100 according to an embodiment of the present invention. figure 1 is a schematic cross-sectional view of a lung sound monitoring device 100 , which includes a suction cup 101 , a sound collection cavity 102 , a circuit body 103 and a prompt output module 104 . The attaching suction cup 101 can be a soft suction cup or an adhesive, which is used to attach to the body of the subject, and can adapt to different body shapes. The lung sound monitoring device 100 can be attached to the subject's chest cavity on the front chest or back through the attachment suction cup 101 . The sound collecting cavity 102 can be a cavity formed by a light rigid material, such as a...

Abstract

A lung sound monitoring device is provided. The lung sound monitoring device includes an acoustic sensor and a processor. The acoustic sensor is configured to capture the chest cavity sound of a subject at a first monitoring position on the subject and convert the chest cavity sound into a first chest cavity sound signal. The processor is configured to receive the first chest cavity sound signal and perform a filter process to obtain a first lung sound signal, and convert the first lung sound signal into a first lung sound spectrum using time-domain frequency-domain conversion. The processor acquires a first intensity index according to the first lung sound spectrum, and outputs a prompt signal according to the first intensity index to indicate whether the first monitoring position is a qualified monitoring position.

Description

technical field [0001] The present invention relates to a lung sound monitoring device, in particular to a lung sound monitoring device and a lung sound monitoring method that can assist in judging the best lung sound collection position. Background technique [0002] At present, the diagnosis of pulmonary obstruction patients is mainly performed by experienced clinicians. The clinicians must personally hold a stethoscope and carefully auscultate several specific parts of the patient's chest cavity before making a diagnosis based on personal experience. Therefore, breath sounds are an important basis for judging the physiological condition of the lungs. [0003] However, patients with chronic obstructive pulmonary disease (COPD) usually have weak breath sounds due to lung obstruction. When recording lung sound, the stethoscope must be accurately placed between the ribs at a specific position, and it is difficult to obtain a good sound collection position in operation. More...
