Stethoscope characterized by a head with a tunable diaphragm. The performance of this instrument are excellent due to the high sensitivity 'sound that characterizes it. Users: - general practitioners - Students - nurses patented tunable diaphragm. The special patented tunable diaphragm ensures the instrument versatility 'and high-quality acoustics. The tunable diaphragm can detect both low-frequency mode (bell) that high frequencies (Iris mode) without turning your head. To switch from one mode to the other is simply change the pressure on the head. Bell Mode (low-frequency) for the detection of low frequencies is sufficient to exert slight pressure on the head. The membrane, mounted on a flexible ring, is thus left free to move and to detect the low frequencies. Iris mode (high frequency) to detect high frequency sounds apply firm pressure on the head. By pressing the head on the skin, the membrane is pushed against the inner surface of the head. Are limited in this way the movements of the membrane: what blocks or attenuates the reception of low-frequency sounds, allowing to listen for those at high frequency. If the stethoscope is held around the neck can occur over time the hardening of the tube is therefore recommended not to keep in direct contact with the skin, for example by holding it above his collar.
