Description

amplified stethoscope

technical field

The utility model relates to the field of medical instruments, in particular to a sound-amplifying stethoscope.

Background technique

In the process of diagnosis and treatment in the hospital, the stethoscope is a frequently used diagnostic tool. Now the doctor uses the stethoscope to determine the frequency of heart activity and the presence or absence of valve murmurs, breathing rhythm and normal and abnormal breathing sounds for the patient, so as to diagnose the possible diseases of the patient. , and make a correct judgment on the auscultation of the patient's respiratory and circulatory system, which requires doctors to often use stethoscopes to assist clinical diagnosis and treatment, and to check patients, but doctors use ordinary earplug stethoscopes for a long time. During the patient's physical examination, sometimes the environment is not quiet, which will affect the effect of auscultation, and affect the doctor's work efficiency for a long time.

Utility model content

The utility model aims at the above-mentioned deficiencies in the prior art, and provides a new type of amplifying stethoscope. The loudspeaker is designed at the back of the earplug, so that the doctor can hear the patient's voice through the loudspeaker without wearing the earplug. Information such as heartbeat increases the doctor's work efficiency and improves the clarity of auscultation. the

The purpose of this utility model is to realize through the following technical solutions:

A kind of amplifying stethoscope, comprises earplug, sound guiding tube, spring plate, auscultation head, described sound guiding tube rear end is provided with earplug, and described earplug rear portion is provided with loudspeaker, and described loudspeaker rear portion is provided with battery, the loudspeaker includes a sound gathering tube, a sound transmission tube, and a sound broadcasting tube. Loudspeaker, the recording tube is connected to the sound amplification circuit board through wires, the sound amplification circuit board is connected to the battery through wires, the speaker is connected to the sound amplification circuit board through wires, the sound broadcast tube is conical, and the sound amplification circuit board is connected to the battery through wires. A spring plate is arranged at the rear of the sound tube, and an auscultation head is arranged at the front end of the sound guide tube.

The utility model has beneficial effects: the structural design is reasonable and practical, the concept is ingenious and novel, the use is simple and convenient, the examination of patients is convenient, and the working efficiency of doctors is improved.

Detailed ways

Below according to accompanying drawing and embodiment the utility model is described in further detail:

As shown in Fig. 1 and Fig. 2, a kind of amplifying stethoscope of the present utility model comprises earplug 1, sound guiding tube 2, spring plate 3, auscultation head 4, and a kind of new amplifying stethoscope is set at sound guiding tube 2 rear ends There is an earplug 1, a loudspeaker 5 is arranged at the rear of the earplug 1, and a battery 6 is arranged at the rear of the loudspeaker 5, and the battery is used to provide power, and the loudspeaker 5 includes a sound collecting tube 7, a sound conduit 8. The sound broadcast tube 9, the sound collecting tube 7 is provided with a recording tube 11, the sound transmission conduit 8 is provided with a sound amplification circuit board 10, the sound broadcast tube 9 is provided with a loudspeaker 12, and the recording tube 11 Connect with the sound amplification circuit board 10 by wire 13, described sound amplification circuit board 10 is connected with battery 6 by wire 13, described loudspeaker 12 is connected with sound amplification circuit board 10 by wire 13, and described broadcast tube 9 is conical, A spring plate 3 is provided at the rear of the sound guide tube 2 , and an auscultation head 4 is provided at the front end of the sound guide tube 2 .

When in use, the doctor places the auscultation head 4 on the patient's heart, and the heartbeat will be passed into the earplug 1 through the sound guide tube 2, and the sound in the earplug 1 is collected by the recording tube 11 in the sound collecting tube 7, and then passed through the transmission After the sound is amplified by the effect of the sound amplification circuit board 10 in the sound conduit 8, the sound is played out by the loudspeaker 12 in the broadcast tube 9, so that the doctor can hear the patient's heartbeat without wearing the earplug 1 of the stethoscope, which relieves the doctor's long time. The pain caused by wearing earplugs 1 increases the doctor's work efficiency.
