A Surgical Loupes Case that Disinfects and Charges

Tech ID:

The purpose of the invention is to limit cross contamination among patients, and between patients and providers who use surgical loupes (loupes). Loupes are a common medical/dental Personal Protective Equipment (PPE) device used to protect the operator’s eyes and magnify their field of view during surgery. Loupes are routinely used in dental and other surgical procedures that produce bio-aerosols and splatter containing viruses and bacteria and are recognized by the Texas Administrative Code as biohazardous after exposure to such aerosols. Loupes are unique in that they are the only piece of PPE which is reusable. Other reusable equipment is autoclaved, exposed to dry heat, vapor or chemical sterilants between patients to destroy pathogens. Loupes are unable to stand these measures due to the delicate construction of their magnifying components. Thus, loupes pose a significant occupational safety and nosocomial infection risk to providers and patients. Further, conflicting guidelines exist between loupe manufacturers on how to clean loupes. Opposing guidelines (use/avoid soap and water, use/avoid isopropyl wipes, use/avoid ethanol wipes, use/avoid AHP wipes) from loupe manufacturers and no protocol from OSHA have led to widespread failure to adequately disinfect loupes between treatments.


Surgical loupes are generally sold with a rechargeable light source which attaches to the loupe’s frame. Similar to loupes, there is no standard protocol for disinfecting these electrical components and their daily recharging uses a separate cable and adapter. This invention simplifies the task of cleaning, storing and charging surgical loupes and their batteries by combining all three tasks into one system. This powered loupes case contains Ultraviolet (UV) Light Emitting Diodes (LEDs) positioned to bathe every part of the loupes with germicidal light and includes a universal USB input to charge loupe light source batteries. This system aims to increase convenience and acceptance of proper PPE disinfection.
