LiteTouch is designed to provide greater wearing comfort and easier delivery of aerosol medication. The mask uses a unique design that molds a clear, hard shell to an exclusive soft-seal interface. It 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 quickly and comfortably conforms to the patients’ facial contours, providing a soft, secure fit for greater comfort as well as improved medication delivery.
