Abstract

A wireless medical stethoscope represents a stethoscope consisting of a transmitter capable of transmitting electric waves and a receiver capable of receiving electric waves, and is characterized in that the auscultation transmitter comprises an auscultation head, a handle, a vibrating diaphragm, an auscultation head cover, an audio collector, a sound pickup device, a transmission circuit board, an antenna, a power supply and a lamp, and the receiver comprises a circuit board, a horn, a frequency-adjusting disc, a sound volume adjustment disc, a circuit board and a receiving antenna. The utility model can convert faint sounds to electrical signals for transmission and later reception. The wireless medical stethoscope can be used for remote auscultation, consultation and education, is adjustable in sound volume, can be used by one or more doctors for auscultation, and can be applied in various fields such as clinical trials, medical care, nursing care and medical and scientific research, especially at an infectious disease ward. As to efficiency improvement, the use of wireless medical stethoscope leads to a shift from noisy wards to quiet offices where doctors can engage in auscultation and consultation with different patients at different wards, thereby enabling more accurate disease diagnosis. Especially, the use of the wireless medical stethoscope leads to a departure from consultation at an infectious disease ward, thereby reducing the risks of doctors getting infected. Moreover, the wireless medical stethoscope can enable doctors to acquire in a technical sense more skills in disease diagnosis, and cause hospitals to attain a higher medical treatment level.
