A kind of medical pediatric stethoscope

technical field

The utility model relates to a medical pediatric stethoscope, which belongs to the field of pediatric medical instruments.

Background technique

In the pediatric outpatient clinic of the hospital, most of the patients who come to see the doctor are small patients with colds and fevers. Before making a diagnosis, the doctors must first conduct a body temperature and cardiopulmonary function test. Auscultation is naturally essential. of. The common stethoscope now includes an oblate hollow pickup, which transmits the sound of the inspection and diagnosis site into the doctor's ear through a hollow tube, but the sound is very weak, and only very experienced medical staff can distinguish it clearly, but some slight Atrial fibrillation requires the use of an electrocardiogram machine to obtain effective data, and the detection efficiency is low.

Most of the existing pediatric stethoscopes are composed of a stethoscope head, listening tube, sound guide rubber tube and earplugs. This stethoscope can only be auscultated by a single doctor. The method is not only cumbersome, but also there will be certain errors in the sound heard each time due to various reasons, resulting in inaccurate consultation. Moreover, when auscultating children, due to their temperament, children tend to be irritable and do not cooperate with the doctor's auscultation. The crying of the children will not only affect the speed of the doctor's auscultation operation, but also affect the emotions of other children when they go to the doctor, causing trouble to the doctor's diagnosis.

Therefore, it is necessary to improve the existing medical pediatric stethoscope to solve the problem that the medical pediatric stethoscope is easy to slip, the distance between the sound guide tubes cannot be adjusted, the children's emotions are difficult to appease, the middle and low frequency sounds are difficult to collect, and multiple doctors cannot conduct consultations, etc. question.
