Abstract
A pediatric stethoscope comprises an annular stethoscope head, wherein a vibration disc is installed at a radiation mouth of the front side of the annular stethoscope head; the rear side of the annular stethoscope head is connected with a sound guide pipe; the sound guide pipe is connected with ear plugs. The pediatric stethoscope is characterized by further comprising a front outer casing pipe and a front inner casing pipe, the rear end of the front outer casing pipe is installed on the annular stethoscope head and is coaxial with the vibration disc, and the front inner casing pipe is located on the inner side of the front outer casing pipe and is coaxial with the front outer casing pipe. The pediatric stethoscope further comprises at least one middle casing pipe between the front outer casing pipe and the front inner casing pipe, the middle casing pipe is coaxial with the vibration disc, the rear end of the middle casing pipe is located in front of the maximum vibration amplitude of the vibration disc and close to the maximum vibration amplitude, the middle casing pipe, the front outer casing pipe and the front inner casing pipe are fixedly connected through a supporting frame, and at least two annular channels are formed among the middle casing pipe, the front outer casing pipe and the front inner casing pipe. By the utilization of the pediatric stethoscope, middle and low frequency real voice can be kept, the middle and low frequency radiation efficiency of a loudspeaker is improved, and doctors can conveniently hear fine heart atrial fibrillation.
Description
technical field
This utility model belongs to a kind of medical apparatus and instruments, especially relates to a kind of pediatric stethoscope.
background technology
Common stethoscope comprises an oblate hollow pick up now, import the sound that checks diagnosis position into doctor's in ear by a hollow pipe, but sound is very faint, only have very experienced medical worker just can offer a clear explanation, but some slight heart atrial fibrillations need to utilize electrocardiograph can obtain valid data, and detection efficiency is low.
Utility model content
