Description

Adjustable stereo/monaural stethoscope

Technical Field

Exemplary embodiments of the present inventive concept relate to a stethoscope, and more particularly, to a tunable stereo/monaural stethoscope.

Background

A stethoscope is a medical device for listening to internal sounds of a human body. Stethoscopes are often used to listen to the lung and heart sounds. Stethoscopes are also used to listen to the blood flow in the intestines as well as in arteries and veins. Since the invention of the stethoscope in 1819, the stethoscope has been used to listen to the internal sounds of the human body as an aid in diagnosing certain diseases or health conditions. Prior to the invention of the stethoscope, the physician listened to the internal sounds of the human body by placing his ears on the patient's chest or elsewhere in close proximity to the patient's body.

Conventional stethoscopes include a sound receiving member (or chestpiece) configured to be placed against a surface of a patient's skin to capture sounds emanating from within the body, such as from the heart, lungs, blood vessels, and the like. Conventionally, there have been two types of sound receiving members, a bell type and a diaphragm type, provided on a conventional stethoscope. The bell type sound receiving member is generally used to obtain a low-pitched sound, while the diaphragm type sound receiving member obtains a high-pitched sound. Doctors may sometimes use a stethoscope having a sound receiving member combined with a bell/diaphragm type. The diaphragm sound receiving member comprises a membrane or diaphragm that selectively vibrates to amplify sound (e.g., heart sounds) from within the body generated within the frequency range of the heart. Sound entering the bell-type sound receiving member or the diaphragm-type sound receiving member is transmitted through a tube connected to an earphone having a pair of pieces configured to be worn in the ear of a physician, nurse or other trained medical professional.

The double-head double-sound-channel and sound-mixing stethoscope has certain advantages compared with a single-head stethoscope when auscultation is carried out to distinguish the positions, time phases and conduction of noise at each jaw, and the double-head double-sound-channel stethoscope is designed. However, the sound channel conversion device has complex design, inconvenient operation, unreliable sound conduction tightness and poor anti-sound mixing interference, influences the auscultation application effect and causes limited clinical application. At the same time, holding two earpieces in two hands is a redundant burden for medical workers who do not need stereo auscultation.

SUMMERY OF THE UTILITY MODEL

In order to solve the above technical problem, an embodiment of the present invention provides an adjustable stereo/monaural stethoscope that is simpler and more convenient to use. The technical scheme is as follows:

the utility model provides an adjustable stereo/monaural stethoscope, including two earpiece earphones, be provided with between two earpiece earphones and connect the elastic component, the sound splitter is connected respectively to two earpiece earphones, be provided with two sound channels in the sound splitter, two sound channel one ends in the sound splitter are connected respectively to two earpiece earphones, two chest listening heads are connected respectively to two sound channel other ends, keep off through the baffle between two sound channels and separate, the baffle can remove so that two sound channels switch on or keep off, the baffle adopts sound-proof material to make, be provided with the connecting piece between two chest listening heads, two chest listening heads can be connected through the connecting piece.

As the priority of the technical scheme, the connecting pieces are clamping joints respectively arranged on the two chest listening heads, and the clamping joints can be connected in a clamping matching mode to realize holding by a single hand.

As the priority of the technical scheme, the inner side wall of the sound divider is a flexible surface, so that when the baffle is in a blocking state, the baffle is tightly matched with the inner side wall of the sound divider to achieve a better sealing effect.

As a priority of the above technical solution, two sound channel portions of the sound splitter connected to the two earpiece earphones are disposed close to each other; the center lines of the two sound channel parts of the sound splitter connected with the two chest earpieces form an included angle, and the center lines of the two sound channel parts face to the middle point of the separation part of the two sound channel parts connected with the two earpiece earphones.

The utility model provides an adjustable stereo/monaural stethoscope, when locating the position of sputum, comparing the intensity of two sounds, judging the time sequence of the two sounds, selecting a stereo auscultation mode, separating the two chest heads, and adjusting the two chest heads to a double-contact double-channel mode; when stereo auscultation is not needed, a monaural mode is selected, the two listening heads are buckled together through the connecting piece and adjusted to be a single-contact double-channel mode, the stethoscope head is more convenient to use, and inconvenience caused by holding the two listening heads with two hands for medical workers who do not need stereo auscultation is reduced.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to fig. 1-4.

The utility model provides an adjustable stereo/monaural stethoscope, which comprises two earpieces 1, a connecting elastic part 2 is arranged between the two earpieces 1, the two earpieces 1 are respectively connected with a sound splitter 3 through hoses, two sound channels 3-1 and 3-2 are arranged in the sound splitter, the two earpieces are respectively connected with two

chest earpieces

4 and 5 through the two sound channels, the two sound channels 3-1 and 3-2 are separated by a baffle 3-3, the baffle 3-3 is made of sound insulation material, the baffle 3-3 can move to lead the two sound channels to be conducted or separated, the end part of the sound splitter is provided with an opening, the baffle 3-3 is inserted in the opening to separate the sound into two cavities to form the two sound channels, a connecting part is arranged between the two chest earpieces, the two chest auditory heads can be connected through a connecting piece.

As shown in fig. 2-3, the two acoustic channel portions associated with the two earpiece earpieces are positioned proximate; the center lines of the two sound channel parts connected with the two chest audions form an included angle, and the center lines of the two sound channel parts face the middle point of the interval part of the two sound channel parts connected with the two ear earphones, so that the sounds of the two ear earphones are more uniform in a monaural state.

The connecting piece is respectively arranged on the clamping joints 6 and 7 of the two chest earpieces, and the clamping joints are matched with each other in a clamping manner to realize the buckling connection of the two earpiece earpieces.

The inner side wall of the sound divider is a flexible surface, so that when the baffle 3-3 is in a blocking state, the baffle is tightly matched with the inner side wall of the sound divider to achieve a better sealing effect.
