Market Summary

Xerostomia is a dryness in the mouth associated with reduced or absent salivary flow. Xerostomia is not a disease, but may be a symptom of medical conditions such as Sjögren’s syndrome, a side effect of radiation to the head and neck (for treatment of cancer), or a side effect of a wide variety of medication. Currently, there are more than 1,800 commonly used medications known to induce xerostomia as a side effect. Dry mouth and resulting dental decay also affects athletes. Dry mouth may significantly impact quality of life, including the ability to eat, speak and swallow.

Technical Summary

Stage IV cancer survivor, Debra Paulsen, has developed a portable, wearable hydrating system for relieving symptoms and reducing adverse impacts of xerostomia. The device includes a pressurized reservoir with an adjustable oral attachment for the delivery of a hydrating liquid in a fine mist that is breathable and may also relieve dry airways. The hydrating content can be water, artificial saliva, medications, or other remedies. The hydrating system may include a base for supporting the pressurized reservoir. The base is designed to be secured and released from an appendage for easy access and portability.
