Technical Field
The utility model relates to the technical field of medical equipment, especially an anti-interference stethoscope of sound attenuation prevention.
Background
The stethoscope is the most commonly used diagnostic tool for internal and external gynecologists, is the mark of doctors, and the modern medicine is the invention of the stethoscope, wherein the appearance and the sound transmission mode of the stethoscope are continuously improved since the stethoscope is applied to clinic in 3, 8 and 3 years 1817, but the basic structure of the stethoscope is not changed greatly and mainly comprises a sound pickup part, a conduction part and a listening part.
The existing auscultation conduction tubes are exposed outside, and the sound conducted in the conduction tubes is easily transmitted to the outside through the conduction tube material, so that the sound volume is attenuated; meanwhile, the auscultation head and the earplugs of the stethoscope are exposed outside, so that the stethoscope is hardly influenced by the outside during auscultation, and noise can enter the auscultation head or the earplugs, so that the judgment of doctors is interfered.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that to above-mentioned technical problem, provide an adopt double-layer tube and have the stethoscope of sound-proof housing to reduce inside volume attenuation, reduce external disturbance, improve and diagnose the effect.
For solving the technical problem, the utility model discloses the technical scheme who adopts is an anti-interference stethoscope of sound attenuation, including the stethoscope, the stethoscope is adorned in proper order by auscultation head, auscultation sound conduction straight tube, sound conduction hose, ears sound conduction straight tube, two earplugs and is connect and form, and its characterized in that still is equipped with the sound-proof housing, the sound-proof housing is the loudspeaker form, the sound-proof housing is including diagnosing first sound-proof housing and earplug sound-proof housing, the auscultation head is installed in diagnosing first sound-proof housing, the earplug is installed in the earplug sound-proof housing.
Furthermore, the auscultation sound guide straight pipe is a double-layer sound insulation straight pipe; the sound guide hose is a double-layer sound insulation hose, and the double-ear sound guide straight pipes are double-layer sound insulation straight pipes.
The sound-proof housing is double-layer sound-proof housing, namely the head diagnosis sound-proof housing and the earplug sound-proof housing are double-layer sound-proof housing.
Further, the auscultation sound guide straight pipe is a double-layer vacuum sound insulation straight pipe; the sound guide hose is a double-layer vacuum sound insulation hose, and the double-ear sound guide straight pipes are double-layer vacuum sound insulation straight pipes.
The head diagnosis sound-proof housing is a double-layer vacuum sound-proof housing, and the earplug sound-proof housing is a double-layer vacuum sound-proof housing.
Furthermore, a contact soft disk is arranged on the edge of the sound-proof cover, the contact soft disk is annular and is made of soft skin-friendly material, for example, the contact soft disk can be made of cotton material, so that the sound-proof cover has affinity when contacting the skin, the sound-proof cover can be sealed with the skin, the patient can be prevented from feeling uncomfortable,
the utility model has the advantages that the sound-proof cover is arranged on the auscultation head and the earplugs, which can effectively prevent the external sound waves from being transmitted to the auscultation head or the earplugs; the auscultation sound guide straight tube, the sound guide hose and the binaural sound guide straight tube are made into the double-layer sound insulation straight tube, so that the conducted sound volume attenuation can be reduced, and the external noise interference can be prevented; the sound attenuation preventing and anti-interference stethoscope not only can effectively isolate noise, but also can reduce sound attenuation of internal conduction, and effectively improves the auscultation effect.

Detailed Description
The present invention will be further described with reference to the following examples.
Example 1.
As shown in fig. 1 and 2, the stethoscope with sound attenuation prevention and anti-interference functions is manufactured on the basis of the existing stethoscope, the existing stethoscope is formed by sequentially assembling a stethoscope head 1, a stethoscope sound guide straight pipe 2, a sound guide hose 3, a binaural sound guide straight pipe 4 and two earplugs 5, a sound-proof cover is additionally arranged on the basis of the stethoscope, the sound-proof cover is horn-shaped and comprises a stethoscope head sound-proof cover 6 and an earplug sound-proof cover 7, the stethoscope head 1 is installed in the stethoscope head sound-proof cover 6, and the earplugs 5 are installed in the earplug sound-proof cover 7. Therefore, the sound-proof shield can be seen by external noise to be separated, and noise interference is reduced.
Meanwhile, the auscultation sound guide straight tube is made into a double-layer sound insulation straight tube 9; the sound guide hose is made into a double-layer sound insulation hose 8, and the double-ear sound guide straight pipe is made into a double-layer sound insulation straight pipe 9; therefore, the sound attenuation in the sound guide pipe can be reduced, and meanwhile, the external noise interference can be blocked.
Example 2.
As shown in fig. 3, the soundproof cover is made as a double soundproof cover 10 in addition to example 1, that is, both the head soundproof cover 6 and the ear plug soundproof cover 7 are the double soundproof cover 10.
Or further, the auscultation sound guide straight tube 2 is made into a double-layer vacuum sound insulation straight tube; the sound guide hose 3 is made into a double-layer vacuum sound insulation hose, and the double-ear sound guide straight pipe 4 is made into a double-layer vacuum sound insulation straight pipe; meanwhile, the head diagnosis sound-proof cover 6 is made into a double-layer vacuum sound-proof cover, and the earplug sound-proof cover 7 is made into a double-layer vacuum sound-proof cover. Therefore, noise can be further isolated, sound attenuation of internal conduction is reduced, and the auscultation effect is effectively improved.
