Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a stethoscope that electrically reads a cardiopulmonary sound of a patient.

[0002]

[Prior Art]

 In a conventional stethoscope, the listening section and the ear insertion tube are connected via a sound transmission pipe, and the cardiopulmonary sound of the patient heard by the hearing instrument is propagated as a sound wave to the ear insertion tube and is directly heard. It was configured to take.

With the above-described conventional stethoscope, since it is worn around the neck at all times during the examination time, there is no significant complication such as stiffness in the shoulder, and volume adjustment for listening cardiopulmonary sounds does not appear. The resulting problem of hearing distress was inevitably accompanied. The present invention aims to solve the above-mentioned problems in the related art by being configured to electrically listen to cardiopulmonary sounds, and at the same time, to enable various uses as a stethoscope. It is a feature.

[Means for Solving the Problems]

 According to the present invention, an auscultation microphone 2 having a shape suitable for listening to cardiopulmonary sounds by contacting the chest of a patient is connected to the input side of the amplifier circuit A, and a headphone is connected to the output side of the amplifier circuit A. A regenerator, etc. is connected, and a recording circuit B for recording the cardiopulmonary sound of the patient, a diagnostic circuit C for making an electrical judgment for the cardiopulmonary sound of the patient, etc. are connected to the output side of the amplification circuit. The present invention relates to a stethoscope configured as described above.

【Example】

 FIG. 1 shows an embodiment of a stethoscope according to the present invention. In the figure, reference numeral 1 is a case body in which an amplifier circuit is incorporated.

Reference numeral 2 denotes an auscultation microphone, which is formed in a shape (a disk shape in the illustrated embodiment) suitable for listening to cardiopulmonary sounds by applying it to a patient's chest or the like. The microphone 2 is configured to be detachably connected to the input side of the amplifier circuit incorporated in the case body 1 via the jack 2a.

Reference numeral 3 denotes a headphone, which is configured to be detachably connected to the output side of the amplifier circuit via a jack 3a.

Reference numeral 4 denotes a connection terminal provided at a required portion of the case body 1 for connecting the output signal of the amplifier to an external device such as a recording device or a diagnostic device.

Reference numeral 5 is a power switch, and 6 is a volume for adjusting the output strength (volume) of the headphones 3.

FIG. 2 shows a block diagram of the present invention. In the figure, the amplifier circuit A is incorporated in the case body 1 as described above. The recording circuit B is basically an external device, but may be configured to be incorporated in the case body 1. It should be noted that the recorded cardiopulmonary sounds were stored and compared with the existing cardiopulmonary sounds recorded periodically to judge whether the medical condition is worsening or recovering, and It is used to check the speed of the.

Further, the diagnostic circuit C is for comparing the detected cardiopulmonary sounds of the patient with the stored data to check the health condition, and if there is a bad place, the diagnosis of the bad place and precautions. It is equipped with a function to display etc. In other words, the diagnostic circuit C is for making an electrical decision (so-called computer-based diagnostic decision) on the cardiopulmonary sounds of the patient. The diagnosis circuit C is configured so that it can be connected not only to receive the current cardiopulmonary sound that has passed through the amplifier circuit A as a signal, but also to make a diagnosis based on the recorded signal by the recording circuit B. ..

By the way, in the illustrated embodiment, the recording circuit B and the diagnostic circuit C are configured to be connected as an external device in order to reduce the size of the main body as a stethoscope, and This is because the flight was planned. Therefore, if it is used as a device to be installed in a medical office or the like, all of these circuits may be integrated. Further, as a device for listening to cardiopulmonary sounds, an appropriate regenerator such as an external speaker may be connected without depending on headphones as shown in the figure, so that a plurality of doctors may make a diagnosis at the same time. ..

[Effect of the device]

 According to the present invention, as described in claim 1, an auscultation microphone 2 having a shape suitable for listening to a cardiopulmonary sound on the chest of a patient is connected to the input side of the amplification circuit A, and the amplification is performed. A regenerator such as headphones is connected to the output side of the circuit A, and a recording circuit B for recording the cardiopulmonary sound of the patient is connected to the output side of the amplification circuit, and electrical judgment is made for the cardiopulmonary sound of the patient. Since the diagnostic circuit C and the like are connected, the stethoscope can be made extremely simple and versatile.

That is, with the conventional stethoscope, because it is worn around the neck at all times during the examination time, it is not possible to adjust the loudness of the cardiopulmonary sounds to be heard, as well as significant complications such as stiff shoulders. Problems such as the resulting hearing distress were inevitably accompanied. On the other hand, according to the present invention, since the cardiopulmonary sound electrically processed through the amplifier circuit is heard through the regenerator such as headphones or speakers, the above-mentioned problems in the conventional art are completely eliminated. Be converted.

Further, according to the present invention, by connecting the recording circuit B for recording the cardiopulmonary sound of the patient, the cardiopulmonary sound of the patient is recorded at regular intervals, and the sound is compared over time. Therefore, the tendency of the patient's medical condition can be confirmed. In addition, by connecting a diagnostic circuit C etc. for making an electrical judgment to the cardiopulmonary sound of the patient, the detected cardiopulmonary sound of the patient is compared with the normal possession data to check the health condition, and If there is a bad place, the diagnosis of that place and cautions can be displayed. That is, the diagnosis can be performed immediately after the auscultation of the cardiopulmonary sounds.

Further, according to the present invention, as described in claim 2, an amplifier circuit is provided in the case body 1, an auscultation microphone 2 is provided at an input portion of the amplifier circuit, and a headphone or the like is reproduced at an output side thereof. If the device is configured to be detachably connected and further the connection terminal 4 for detachably connecting the recording circuit B, the diagnostic circuit C, and the like is provided in the case body 1, it is possible to make the entire unit significantly compact. Therefore, it is most suitable for carrying in a home visit.

Further, according to the present invention, when the recording circuit B and the diagnostic circuit C are integrated together with the amplifier A as described in claim 3, the present invention is intended for installation in a visit room having space. It is optimal, and in this case, various functions such as speaker installation and image processing for medical examination can be incorporated.
