Revolutionary Microelectronic Device Prevents Contamination of Stethoscopes

About 85% of stethoscopes are contaminated with bacteria, including pathogens. An EU-funded project offers an innovative solution to reduce these alarming numbers.

HEALTH
Healthcare-related infections are a major concern because they are associated with high rates of morbidity and mortality. The highest risk individuals are the elderly, preterm infants, immunodeficiency patients, transplant patients and those in intensive care. One of the common sources of these infections is medical equipment, such as the stethoscope. Although many in the scientific community emphasize the need to disinfect them, finding an adaptable, practical and easy solution is complex.

All this, combined with the fact that there is no reference standard for disinfection, only aggravates the situation.STET CLEANevaluated the effectiveness of a device for disinfecting stethoscope membranes in a real-life setting. “The STET CLEAN product is an innovative microelectronic device equipped with ultraviolet-C (UV-C) light-emitting diodes (LEDs) that were invented, designed and manufactured by egoHEALTH to enable hospitals and healthcare centers to disinfect their membranes. stethoscopes in a fast and automatic way, “explains Professor Gabriele Messina, coordinator of the project. “This device is lightweight, portable and customizable.

It is also practical, technologically innovative, efficient and effective, safe for the operator and for the patient, economical and environmentally friendly, “continues Professor Messina. The device was designed so that it can fit into the pocket of a coat, be placed on a belt or placed on the desk. Once the stethoscope horn is attached to the device, it is automatically disinfected by UV-C radiation from an LED. The device consists of a battery-powered, rechargeable via a micro-USB connector, and a microcontroller providing a custom current to the UV-C LED and system.

To prevent lesions caused by UV-C light, its emission is possible only when the stethoscope’s flag is attached to it. The conclusions of phase 1 “During phase 1 of the project, we wanted to increase our knowledge in order to obtain a greater penetrability of the product in a sanitary environment,” says Professor Messina. Project partners have discovered that they should review and add more settings in the future in order to further increase the performance of the device and make its use universal and cost-effective.

This will prove to be essential as “the latest advances in UV-C LEDs are coming to the market quickly and competitively,” added Professor Messina. The project team also found that some of the strategies adopted will need to be revised. For example, future technological advances that may have an impact on the selling price.

“We also evaluated again some ideas that were good, the hypothesis of developing a simpler and less expensive version of the product for certain markets or the possibility of producing a version that can not be carried in a pocket but which is permanently attached to the stethoscope’s roof “, confirms Professor Messina. “We plan to continue writing a business plan that will implement this acquisition of new knowledge.

We are evaluating possible partnerships to support the product, not only in the engineering phase but also during the distribution phase, “concludes Professor Messina. Much more can be expected from STET CLEAN. A “We plan to continue writing a business plan that will implement this acquisition of new knowledge.
