LiteTouch is designed to provide greater wearing comfort and easier delivery of aerosol medication. The LiteTouch mask fits onto the mouthpiece of a Philips Respironics OptiChamber Diamond valved holding chamber (VHC) and functions by simply touching the mask seal lightly to the patient's face. It is detacheable for easy replacement and cleaning. The LiteTouch's unique design features a clear, hard shell molded on to a soft-seal interface. The soft-seal quickly and comfortably conforms to the patient's’ facial contours, providing a soft, secure fit for greater comfort as well as improved medication delivery when used with metered dose inhalers (MDI).
