Abstract: A stethoscope disinfection system comprising a guide member comprising a body member, a rotation-imparting member, a slide guide track, a spring guide track, and a trolley guide track, and a trolley comprising a lower housing member, a cam member, a lock head, a spring apparatus, a brush member, an upper housing member configured to receive at least a portion of a head of a stethoscope, and a dispersing member positioned in the dispersing mechanism chamber. The system may further comprise a slide guide configured to engage with each of the arm of the lock head and the slide guide track and to translate along a length of the slide guide track.

Abstract: A method for personalizing a stethoscope, wherein the personalization permanently identifies the owner of the stethoscope and also decorates the stethoscope. The personalization does not deter from the normal operation of the stethoscope, and allows for full sterilization of the stethoscope. The diaphragm of the stethoscope, includes an exterior side that is adapted to come into contact with the patient and, an interior side that is not exposed to the outside. A design selected by the owner is applied, in reverse, to the interior surface of the diaphragm. The design is preferably painted on the diaphragm in stages, or layers. Using the present reverse application technique, images painted on the right-half of the interior surface, appear on the left-half, when viewed from the exterior of the stethoscope. Further, in the present application technique, the foreground is painted on, or applied, first, and the background of the personalization is applied last.

Abstract: A stethoscope with a figure-eight configuration designed for one-handed operation and further comprising improvement to the headpiece resonance chamber. The ear tubes of the stethoscope are roughly S-shaped and together form a figure eight design. The lower portion of each ear tube is connected by a resistant force mechanism that maintains the stethoscope in the closed configuration. By applying one-handed compressive force to the resistant force mechanism attached to the lower portion of the stethoscope's figure-eight construction, the earpieces are separated and the stethoscope adopts the open configuration. Both the headpiece and the diaphragm are interchangeable to allow a variety of different shapes and sizes.
