In a 2009 study, 78% of all stethoscopes were infected with MRSA, Staph, or other microorganisms. CoreShieldz™ is a fast, effective, and affordable solution to help stop the spread of microorganisms from patient to patient via the stethoscope. The stethoscope is often the first action of a practitioner’s engagement with a patient, beginning the diagnosis and treatment process. Yet, science has proven that the stethoscope is a vector for microorganisms. The stethoscope continues to be a potential source of transmission of various microorganisms from patient to patient. CoreShieldz™ is a cover for the stethoscope that should be discarded after each use. It adheres to the stethoscope but does not stick to patients’ skin or clothing.
