Intelligent multifunctional stethoscope

Abstract

The invention discloses an intelligent multifunctional stethoscope, which comprises traditional and electroacoustic stethoscope components. The electroacoustic stethoscope component comprises two sound pickups, a pair of auscultating heads provided with micro speakers and a hardware box, wherein a circuit in the hardware box comprises a singlechip, a power amplifying circuit and a wireless transmitting module; and the singlechip comprises a microprocessor, an analog-digital and digital-analog conversion circuit, a memory chip and a USB interface circuit. The intelligent multifunctional stethoscope is characterized in that a microphone channel comprises a cavity of the hardware box, a rubber tube which is arranged in the center of the lower bottom surface of the cavity and is provided with a sound head at the outer end thereof, and two sections of rubber tubes arranged on two sides of the upper top surface of the cavity, wherein the outer ends of the two sections of the rubber tubes are inserted with an L-shaped metal bent pipe respectively and the end heads thereof are provided with the auscultating heads; the microphone channel also comprises a U-shaped elastic metal connecting sheet of which two ends are sleeved on the lower part of the bent pipe respectively; and one sound pickup is arranged in a cavity of the sound head, while the other sound pickup is arranged on the top surface of the hardware box. The electroacoustic stethoscope component can also be provided with a corresponding wireless transmitting and receiving device so as to achieve distant auscultations and diagnoses.

Description

technical field [0001] The present invention relates to a medical device and a medical teaching device, especially a device that can realize traditional auscultation function or / and electronic auscultation function or / and realize non-bedside remote auscultation and diagnosis through wireless transmission, and can simultaneously perform medical Stethoscope for teaching. Background technique [0002] In order to overcome the defects and deficiencies that exist respectively in traditional stethoscopes and electronic stethoscopes, I have previously applied for a utility model patent called "multifunctional composite stethoscope". The patent number of this patent is 200620095395.9, and the announcement number is CN201005711Y. The stethoscope includes a traditional auscultation device and an electroacoustic auscultation device, and its sound transmission channel includes an air-borne sound transmission channel and / or an electroacoustic amplification sound transmission channel, wh...

AI Technical Summary

Problems solved by technology

[0004] 1. The design of the connection tube between the ear end (ie the stethoscope head) and the hardware box is unreasonable. If the tube is rigid, it is difficult for the ear end to match the insertion distance between the two ears of different doctors. Adaptation, that is, there is no guarantee of proper insertion; if the tube is a rubber hose, it is difficult for the hose to bear the weight of the hardware box and pickup head below it to deform and move the position, so that the stethoscope is removed from the doctor's ear Falling off, it can also be said that the stethoscope is actually unusable;

[0005] 2. One of the pickups is set at the lower end of the hardware box, which is too far away from the patient's examination site, so that the collected stethoscope is greatly weakened, and its auscultation effect is poor;

[0006] 3. The micro-speaker is set at the end of the ear-connecting end, which is far away from the doctor's ear, which weakens the doctor's auscultation effect;

[0007] 4. The circuit design of the electroacoustic auscultation part is not perfect. The two pickups are pre-amplified without a filter circuit, so the noise is not filtered out, which affects the clarity of the auscultation sound and the teacher's explanation sound

[0008] 5. The stethoscope does not have the functions of remote auscultation and diagnosis, so it is difficult to adapt to the new trend of medical service expansion
