Abstract

A digital stethoscope includes a body, an ear tube, a sound transferring member, a lever, and a linkage body. The body includes a channel and a first through hole. The ear tube is connected to the body via the channel. The sound transferring member is disposed on a first opening at the bottom of the body and includes a chest piece. The lever is engaged with the body through the first through hole. The lever is slidable between a first position and a second position of the first through hole. The speaker is disposed in the first hole and the microphone is disposed on the second hole. When the lever is in the first position of the first through hole, the speaker covers a third opening of the channel and the microphone covers the second opening of the chest piece. The digital stethoscope is in the digital auscultation mode. When the lever is in the second position of the first through hole, the speaker is away from the third opening of the channel and the microphone is away from the second opening of the chest piece. The digital stethoscope is in the normal auscultation mode.

Description

Digital stethoscope

The invention relates to a digital stethoscope, in particular to a digital stethoscope which can be switched to a general stethoscope when the battery is exhausted.

A stethoscope is a medical instrument used to listen to the sounds inside the human body, such as the sound of the heart and lungs. The front end of the stethoscope is a membrane cavity with a large area, while the end inserted into the ear has a narrow cavity, the gas vibration amplitude will be larger than the cavity, which can amplify the sound wave vibration in the patient.

Digital stethoscopes use new technology to design stethoscopes so that health care workers can have better equipment to improve the quality of care. Capturing the sound in the body, and then converting it into an electronic signal and performing amplification, filtering, and other signal processing can improve the sound signal provided to the physician and improve the diagnostic quality. Reverting the electronic signals that can represent the human body's voice to digital form is more conducive to the use of a large number of computer-related technologies that are currently widely used for data storage, transmission and processing. Such applications include incorporating the recorded human voice into a transformed electronic case, and replaying the human voice for analysis by one or more physicians. When transmitting digital audio files through electronic data networks, additional advantages can be achieved. The above-mentioned advantages include being able to be used for remote diagnosis, cooperative consultation for medical personnel located in different regions, and the use of remotely installed medical computing services, including automated expert system diagnosis and ethnic-level analysis of data from multiple patients.

However, the digital stethoscope has been running out of battery. If the battery of the digital stethoscope is exhausted and the doctor does not have a traditional stethoscope, it cannot be used. Therefore, there is a need to design a structural device so that the digital stethoscope can continue to be used for auscultation by doctors without electricity.

The purpose of the present invention is to disclose a digital stethoscope, through which the digital stethoscope can be converted into a traditional stethoscope when the battery is exhausted, so that the doctor can continue to use it.

According to the above purpose, the present invention discloses a digital stethoscope, including: a main body including a channel, a first perforation and a first opening; a sound-transmitting element is disposed at the bottom of the main body and includes a listening chest piece, the The listening chest piece includes a second opening aligned with the first opening; a lever is engaged with the main body through the first perforation and slides between a first position and a second position of the first perforation , And includes a second perforation; and a linkage, including: a combination, including: a first through hole, located on the side of the assembly; a second through hole, located on the bottom of the assembly; And a convex block, which is arranged at the bottom of the assembly and is adjacent to the second through hole, the convex block is engaged with the second perforation of the lever, so that the lever is linked with the link body; a speaker is provided at In the first through hole; and a microphone, disposed above the second through hole.

The purpose of the present invention is to propose a digital stethoscope, which allows a doctor to switch between a digital stethoscope and a general stethoscope, so that the doctor can use it more conveniently.

According to the above purpose, the present invention discloses a digital stethoscope, including: a main body including a channel, a first perforation and a first opening; a sound-transmitting element disposed on a first opening at the bottom of the main body and including A listening chest piece, the listening chest piece includes a second opening aligned with the first opening; a lever is engaged with the main body through the first through hole and slides at a first position of the first through hole Between a second position, and including a baffle, the baffle is located above the listening chest piece, and the baffle includes a third opening; and a speaker, is disposed inside the main body, and adjacent to the channel; and A microphone is arranged at the bottom of the main body and above the baffle.

The advantage of the invention is that it can be switched randomly between a general stethoscope and a digital stethoscope, so that medical staff can use the digital stethoscope at any time without worrying about the problem of power consumption.
