Problems solved by technology

[0002] Stethoscope is a necessary diagnostic tool in Cardiology. However, the existing stethoscope is heavy, and the doctor hangs it on the neck for a long time, which makes it very uncomfortable. In addition, the existing stethoscope needs to be listened to in a quiet environment. Small, it is difficult to pre-diagnose some diseases in the Department of Cardiology through the stethoscope, delay the patient's condition, or require further inspection, the inspection cost is high, and it is urgent to improve the existing stethoscope

Abstract

The inVention relates to the technical field of medical instruments, and discloses a cardiologic stethoscope. The cardiologic stethoscope comprises a stethoscope head, a horn-shaped sound amplifying barrel, an amplifying box, an earphone connector, an earphone line and two earplugs. Sound holes are formed in the stethoscope head, the stethoscope head is communicated with the amplifying box throughthe horn-shaped sound amplifying barrel, the earphone connector is embedded into the amplifying box, and a metal Vibrating diaphragm, a conductiVe substrate, a power source, a resistance wire and a loudspeaker are arranged in the amplifying box. The metal Vibrating diaphragm is connected with a negatiVe electrode of the power source through a resistance wire, a positiVe electrode of the power source is connected with the conductiVe substrate through a control switch, the control switch is embedded into the amplifying box, and a distance exists between the metal Vibrating diaphragm and the conductiVe substrate and is matched with the amplitude of the metal Vibrating diaphragm. The loudspeaker and the resistance wire are connected in parallel, and the earphone connector is connected with the loudspeaker. According to the cardiologic stethoscope, heart sounds are primarily amplified and conVerted into electric signals to be amplified again, the precision of the stethoscope is improVed, and a doctor can work easily.
