Description
Technical field
This utility model relates to a kind of internal medicine stethoscope.
Background technology
Stethoscope is the most important medical diagnosis on disease apparatus of internal disease, and almost all leave will be by means of stethoscope in all medicals diagnosis on disease of this section.Existing stethoscope all is to rely on an arcual steel sheet spring two listening pieces to be pressed on doctor's ear place.Because the elastic force of this arc steel plate spring is fixed, and the distance between everyone two ears is not quite similar, through regular meeting the phenomenon that listening piece is oppressed tension appears for many doctors therefore, and let user feel uncomfortable especially.
Summary of the invention
The goal of the invention of this utility model is to provide a kind of internal medicine stethoscope, uses this stethoscope can avoid the discomfort that causes because of listening piece compressing tension.
The technical scheme of this utility model is: the retaining thread lengthening between the inner of the left and right transmission sound pipe on this stethoscope top and the left and right listening piece knob; Promptly increase by a segment length again and regulate screw thread 1-2 centimetre knob spacing; The retaining thread that the length of two listening piece knobs is established in reaching also extends accordingly, regulates in the knob spacing back of the body medicated cap nut is housed on the screw thread.
The method for using of this utility model is; Cause ear not in good time when arc steel plate spring tension occurring, can rotate back of the body medicated cap nut and listening piece knob, make the distance of two listening piece knobs become big, thereby will subtract the pressure of the light knob of listening piece ear.
The beneficial effect of this utility model is simple, convenient and practical, can avoid the discomfort that causes because of listening piece compressing tension effectively.
