Description

Electronic Stethoscope {Electro-stethoscope}

The present invention relates to an electronic stethoscope, and more specifically, to form a microphone to use the head portion of the existing stethoscope, and furthermore, the automatic sound recognition diagnostic function that can distinguish the physical sound and the characteristic sound input The present invention relates to an electronic stethoscope capable of providing accurate diagnostic information as well as learning to improve the doctor's stethoscope ability by providing a diagnosis name with the closest waveform and sound through the monitor so that the doctor can refer to the diagnosis.

In general, a stethoscope is a very important medical equipment that allows the medical person to guess the human condition of the medical person by collecting the sound generated from the organs inside the human body, particularly the heart or the lung, and providing the medical person.

Therefore, the accuracy and reliability of the sound picked up by the stethoscope are very important variables that determine the physical condition of the examinee. Such stethoscopes are classified into analog and digital methods.

The analog stethoscope is still widely used in the medical field and is gradually being converted into a digital stethoscope. In particular, in recent years, as the remote medical care using a communication network is becoming more common, a digital stethoscope is drawing attention.

On the other hand, when the stethoscope is conventional stethoscope, it is difficult to detect minute changes in the heart and breath sounds, and according to the subjective judgment of the doctor, the error rate is relatively high. At least one auscultation and exhalation should be auscultated in one position, but a lot of time was wasted in auscultating in various positions.

In addition, in the case of hearing difficulty patients and children, the spontaneous spontaneous breathing (breathing breathing) is often not cooperative when the doctor listens to the breathing sounds, it is difficult to diagnose the disease with the conventional general stethoscope. That is, it is often difficult to listen to the breathing sound only by breathing normally.

And if you have dirty skin or skin disease, or if you feel shy when you take off your clothes, it is difficult to use a conventional stethoscope for your stethoscope while wearing your clothes. Not only could it be detected, but the sound could not be adjusted.

On the other hand, the digital electronic stethoscope adopts a method of collecting sound by inserting a microphone into a rubber tube extending inside the head of the stethoscope, which is sealed by a sounding plate and a rib.

Therefore, although an electronic stethoscope has been proposed incorporating a microphone in the input device of a conventional general stethoscope, the input device has many deformations in order to embed the microphone, so that only a diaphragm type diaphragm is used. In other words, the bell type, which is excellent for listening to low tones (heart sound), was omitted.

In addition, since all the stethoscopes or diaphragm heads (circumference rubber packings) of the conventional stethoscope are applied to the electronic stethoscope as they are, there was a problem of severe rejection for the stethoscope due to severe noise when touching or touching the human body.

The present invention has been made to solve the above problems, the object of the present invention is to connect the microphone of the electronic stethoscope and the head portion used in all existing stethoscope, and fixed packing of the diaphragm of the head portion And by changing the bell type rubber circumference packing device to fabric material, it can minimize the noise caused by friction and vibration on the skin and cloth of the human body, and can distinguish the pathological characteristic heart sound as well as the waveform generator program on the body of the electronic stethoscope.
