Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Example 1

Referring to fig. 1-3, a stethoscope for cardiology department includes sound tube 6, and sound tube 6 upper end fixedly connected with ear pipe 2, 2 stainless steel ear pipes of ear pipe, because sound transmission decay reduces in the heavy metal, ear pipe 2 adopts stainless steel ear pipe, loss when can reducing the sound transmission.

The earplugs 1 are clamped on the opposite inner sides of the two ear tubes 2, the lower end of the sound transmission tube 6 is connected with a chest piece 8, the upper end of the chest piece 8 is fixedly connected with a holding column 9, the holding column 9 is designed to facilitate the movement of the chest piece 8 and auscultation of different parts, the anti-slip veins 4 are arranged around the holding column 9 at equal intervals, the design of the anti-slip veins 4 increases the friction force, the lower end of the holding column 9 is fixedly connected with a sound-proof cover 7, the sound-proof effect is achieved by the design of the sound-proof cover 7, the interference caused by the external sound during auscultation is prevented, an elastic mechanism is arranged between the two ear tubes 2, the sound is transmitted from the chest piece 8 to the ears of a doctor through the ear tubes 2 of the sound transmission tube 6 by placing the chest piece 8 on the auscult,

acoustic pipe 6 includes elastic layer 10, elastic layer 10 is made for the butadiene rubber material, acoustic pipe 6 elasticity has been strengthened, prevent when folding crooked to acoustic pipe 6, cause the damage, be favorable to the life of stethoscope, elastic layer 10 inboard fixed bonding has puigging 11, puigging 11 is made for abs resin, play syllable-dividing effect, prevent that the foreign tone from causing the interference, the anti tear resistance of acoustic pipe 6 has also been strengthened simultaneously, 11 inboard fixed bonding of puigging has puigging 12, puigging 12 adopts the PVC material to make, the characteristics that have the sound effect, loss when can reducing the sound transmission, elastic layer 10 is 1 with the thickness ratio of puigging 11: 1.
