Description

[Detailed description of the device]

[0001]

[Industrial field of application] The present invention is intended to significantly improve the accuracy of a stethoscope, which is a medical tool indispensable for diagnosing human or animal diseases. It relates to a stereotype stethoscope in the medical field to be obtained.

[0002]

2. Description of the Related Art Heretofore, in this type, the following has been done. Stethoscope is Lann 1819
It started with the one for ears created by ec, and after that, improvements were made and a stethoscope for both ears was developed,
The auscultation unit had one sound collector (vibration plate), and one tube connected to this was divided into two under the chin and transmitted to both ears. Therefore, he was listening to monaural sound only at the auscultation site. This has not changed for 173 years since the invention.

[0003]

The problems described in the prior art have the following problems. 1. Since there was only one diaphragm, I was listening to monaural sounds, so it was difficult to capture the direction of movement such as heart sounds, alveolar sounds, and peristaltic sounds. 2. At the time of auscultation, the conventional one had to have a sound collecting part or an arm part. 3. It was not possible to expand the auscultation range and hear two sounds at the same time. 4. It was not a three-dimensional auscultatory sound.

The present application has been made in view of the above problems of the prior art, and an object of the present application is to provide the following. It is intended to make the auscultation sound of the conventional technology louder in a three-dimensional manner and to significantly improve the diagnostic accuracy of a doctor or veterinarian's stethoscope.

[0005]

[Means for Solving the Problems] In order to achieve the above object, the present invention is as follows. That is, in the present application, the left and right earpieces 2A and 3A are attached to the upper ends of the left and right ear tubes 2 and 3, and the sound collectors 6 and 7 are attached to the lower ends of the left and right tubes 4 and 5, respectively. The upper portions 4A, 5A of the left and right pipes 4, 5 are substantially in front of each other via a connecting portion 8 interposed between the left and right pipes.
The upper ends 4A1 and 5A1 of the left and right ear tubes 2 and 3 are connected and communicated with each other in a curved shape, and the predetermined positions of the left and right tubes 4 and 5 are bundled into one bundle.
Well, the diaphragm gap adjuster 9 attached there is only one
A tubular body 9A that holds the left and right tubes 4 and 5 in a bundled state,
Located at the center of this tubular body and between the left and right tubes 4, 5.
Fulcrum 9B provided so that it opens like a scissors.
Consists of left and right arms 9C and 9D pivotably attached
When the arms 9C and 9D are viewed from the side,
Stereo type listening that is configured in a slightly curved state
It is a medical instrument.

[0006]

【Example】 Examples will be described with reference to the drawings. 1
Is a stereo-type stethoscope of the present invention. 2 and 3 are left and right
Ear tubes (gold ears) with left and right ear pieces 2 at the top
A and 3A are attached respectively. 4,5 are left and right
Tubes and sound collectors (vibration plates) 6 and 7 attached to the bottom
Have been killed. And the upper part 4 of the left and right tubes 4, 5
A and 5A are curved between the right and left tubes in a substantially U-shaped front shape.
Are connected in the same manner, and the upper ends 4A1 and 5 of the respective
A1 is connected and communicated with the lower ends of the left and right ear tubes 2 and 3.
It 8 is a stopper provided between the upper portions 4A and 5A
is there.

Numeral 9 is a bundle of right and left tubes 4 and 5 at predetermined positions.
The structure of the diaphragm gap adjuster attached there
Is a tubular body that holds the left and right tubes 4 and 5 in a bundle.
9A and the center of this tubular body, and between the left and right tubes 4, 5
The fulcrum 9B provided to be located at
Left and right arms 9C and 9D pivotally attached in a scissor-like manner
The upper part of the arms 9C and 9D is
Handles 9C1 and 9D1 having an elliptical mouth for inserting
And the lower portions 9C2, 9 of the arms 9C, 9D
D2 supports the left and right tubes 4 and 5 in a held state.

The arms 9C and 9D are viewed from the side.
It is configured to bend gently outward when viewed.
It In this case, the lower parts 9C2, 9C of the arms 9C, 9D
D2 is the arms 9C and 9D (collected sound from the sound collector).
(The part that conveys the pipe to the pipe) and wrap the joint between pipes 4 and 5 from above.
It is configured to hold the sound collector and tube.

The present invention operates as follows. 1. Vibration of the left side, using 2 diaphragms and 2 tubes
The sound is transmitted to the left ear and the vibration sound to the right is transmitted to the right ear.
Therefore, the vibration sound is heard in the stereo state in the ear,
I was able to hear a three-dimensional sound louder than a stethoscope. That
As a result, in the case of pneumonia, wet and dry Russell sounds
Distinction, organic intracardiac murmur and epicardial murmur, intestinal peristalsis
The sound, especially the direction of flow of the contents of the convulsions of the horse, is clarified.
Hearing and diagnostic accuracy in medical treatment are significantly improved
become.

2. Two from two sound collectors (diaphragm)
A collection of tubes that are bundled together and provided with a diaphragm gap adjustment section.
The sound collector gap can be adjusted freely, and two sound collectors
Listening to a three-dimensional vibration sound by freely setting the distance between
It will be possible. 3. The arms 9C and 9D of the diaphragm gap adjusting unit 9 are side surfaces.
As seen from the outside, it is gently curved outward
Therefore, adjust the handles 9C1 and 9D1 shown in FIG.
This makes it easier to apply the two diaphragms to the auscultation site.
it can.

[0011]

[Effect of device] The present invention is constructed as described above.
The following effects are achieved. Conventional monaural vibration sound
The effects of listening to the stereo vibration sound from
It is Ri. 1. Heart Sound Sound I (ventricular contraction sound) and sound II (ventricular dilatation sound)
Sounds bigger and three-dimensional than the ones. As a result, organicity
Intracardiac murmur (valve thickening, edema, atrophy, perforation, calcification, healing)
Acupuncture, wart-like growth) can be auscultated more accurately than conventional ones.
You can In addition, extracorporeal murmurs (pericardial friction sounds, water pulsations)
Since it sounds three-dimensional, the directionality can be inferred.

2. Alveolar Sound (Vesicular Mur)
mur) Wet Russell sound (tracheal catarrh, cataract ) heard in pneumonia
Pneumonia, pulmonary edema, necrotizing pneumonia, aspiration pneumonia, etc.), twisted hair
The part of the sound is heard more efficiently than the conventional one, and the chest of shaking sound
The horizontal plane when stored in the cavity is better guessed than the conventional one.
Wear. 3. Peristaltic intestines, spasms in horses, small bowel sounds, gurgling, flu
Flowing Liquid, Water Splashing (spl)
ashing strength, frequency, ratio, etc.
And the movement of the sound source, which is a characteristic of the stereo state, is three-dimensional.
You can listen to. This can be heard with conventional stethoscopes
There wasn't. Also, the metallic sound of the caecum of the cow (Pingsou)
nd), colon, tambling of the large intestine, far
Clearly understand the sound of the rumble and the direction of flow
It

To summarize the above, the following effects can be obtained.
Becomes 1. The auscultatory sound sounds loud in three dimensions, and the diagnostic accuracy is
It was much better than anything. 2. A diaphragm gap adjuster is provided so you can hold it with one hand
Easy, easy to crimp to the auscultation part on the body, and this
Freely range can and Hirogeruko by opening and closing
It 3. The arms 9C and 9D are gently outward when viewed from the side.
Since it is configured in a curved state,
It is easy to attach the to the auscultation site.
