EMI shielded windows with integrated touchscreen meet operating-theatre needs

November 21, 2013 // By Graham Prophet
Chomerics Europe has gained a design win for its shielded window products with a designer and manufacturer of cardiovascular medical devices. The windows, which also incorporate a resistive touchscreen, are used on operating theatre-based equipment; 14-in. EMI shielded windows help ensure reliable operation and meet clinical environment standards in pacemaker programming equipment.

The sub-system is able to meet the extremely stringent quality requirements that are crucial for medical equipment designed for use in surgical environments. The 14-in. shielded windows are constructed in a controlled manufacturing environment, so that there are no inclusions or entrapment of contaminants between the various layers that are bonded together to make a shielded optical window with touchscreen.

Operating theatres are well lit environments and therefore displays used must achieve maximum light transmission and have high image clarity. The specialist mesh and other materials used by Chomerics helped achieve light transmission performance that was significantly improved versus that of previous equipment. Shielding against electromagnetic interference (EMI) is an important aspect of medical electronic equipment design. Failure to manage EMI effectively can severely impact the reliability of the equipment and that of products situated in the immediate vicinity.
