ABSTRACT:
A system for preventing nosocomial infection and contamination through usage of a stethoscope, utilizing a stethoscope sleeve and fitting accessory configured to be utilized in conjunction with off-the-shelf stethoscopes and the like. A first embodiment (FIGS. 1 & 2b) includes a one-use, disposable sleeve, wherein the head or diaphragm-retaining ring is covered in its entirety, with the full covering up of the body to the ear tubes, the cover being composed of a bacterial, viral, and fluid impermeable, acoustically transparent medium. The accessory includes a spreader attachment removably affixed to the upper body of the stethoscope and containable within the sleeve when mounted on the stethoscope. In combination with the spreader attachment accessory, the system provides a sterile system for preventing infection which isolates the stethoscope from both the user as well as the patient, greatly reducing any risk of contamination. A second embodiment (FIGS. 3 & 2a), designed for reducing the spread of infection among health care workers sharing a patient dedicated instrument during reverse isolation technique, utilizes substantially the same sleeve but which further includes a handle apparatus affixed to the wishbone portion of the instrument, allowing the ear caps of the instrument to be spread for engaging and disengaging the instrument from the various health care workers, without the necessity of touching the body of the instrument during use, thereby preventing cross infection during the consequential sharing of the dedicated stethoscope by the various health care providers.
