The energy efficient laryngoscope range replaces traditional metal instruments with innovative polymer handles and a range of “engines” suitable for different environments. Engines include a kinetically powered unit removing the need for batteries or power supplies unavailable in remote locations or disaster relief situations alongside rechargeable options. These innovative engines combine with both sterile, super low cost disposable handles and robust pioneering polymer handles capable of repeated sterilization for safe, reliable and functional laryngoscopy accessible globally.
