Description

A kind of multifunctional anti-noise stethoscope

technical field

The invention belongs to the technical field of auscultation medical instruments, in particular to a multifunctional anti-noise stethoscope.

Background technique

Stethoscope (stéthoscope) is the most commonly used diagnostic tool for internal and external gynecologists, and is a symbol of doctors. Modern medicine begins with the invention of the stethoscope. Since the stethoscope was used clinically on March 8, 1817, its shape and sound transmission method have been continuously improved, but its basic structure has not changed much. (ear pieces) composition.

At present, there are many people in the hospital and the noise in the hospital is high. During the doctor's auscultation, the noise of the external environment often affects the sound effect transmitted to the ear; in addition, when auscultating a specific part, the body itself also has breathing sounds and bowel sounds. Interfering sounds such as tones, sometimes when auscultating a special part, it is easy to be slightly disturbed by the above-mentioned noises, resulting in difficult and inaccurate diagnosis. Moreover, because there is no external power supply intervention during the entire transmission process, the sound level is fixed and cannot be adjusted, and the effective distinction and judgment of the following special sounds cannot be realized by adjusting the sound level. As a result, the existing traditional stethoscope can only judge the patient's condition by rough filtering. Judgment accuracy is poor.

Another problem involves the teaching of auscultation for young doctors. Most of the existing stethoscopes are designed for a single pair of listening parts. In clinical diagnosis, the teaching is usually realized through oral expression by experienced doctors, because there are few young doctors due to time and other issues. Hearing the voices of different patients directly makes the learning method of young doctors not intuitive enough, resulting in long learning time and poor learning effect, which increases the cost of building a doctor team and the difficulty of teaching for experienced doctors.

There is also a problem: the existing stethoscopes all include a conduction part, because the setting of the conduction part requires the doctor to check the patient's distance to be limited by the conduction part, so that the doctor or the patient is required to adjust to a suitable distance to realize the inspection; When examining patients in supine position, doctors usually need to bend over for detection, which brings some discomfort to doctors.

Therefore, for the above-mentioned technical problems involved, it is necessary to design a stethoscope that includes an external power supply, a wireless transmission structure, a double earphone structure and other reasonable and effective structures, and effectively and reasonably combine each structure to obtain a stethoscope that realizes the above-mentioned functions.

According to the prior art, the present invention provides a multifunctional anti-noise stethoscope according to the technical problems such as many noises in auscultation, limitation of auscultation by transmission part and inability to realize effective learning and teaching effects.
