Abstract: A nasal cannula retainer has a flexible member and cannula grips. The flexible member has a central nose portion with an adhesive backing for adhering to a patients nose and two cheek portions connected to the nose portion, each of the cheek portions having an adhesive backing for adhering to a patient's cheek. The adhesive layers are covered with a peel layer which is removed prior to applying the retainer. The cannula grips are attached to the cheek portions to secure a nasal cannula on each of the patient's cheeks. The grips are releasable and reusable, allowing the cannula to be repositioned or temporarily removed without the need for the retainer to be discarded and replaced, and without the use of tape to secure the cannula to the retainer after the cannula is repositioned.

Abstract: Disclosed is an improved grip for tennis rackets. The grip is inversely tapered such that it narrows moving along the axis of the handle away from the head of the racket. Further, the grip is hexagonal in cross-section. In other words, the grip is substantially a truncated hexagonal pyramid. This design is structurally compatible with the skeletal and muscular structure of the human hand, wrist and arm. The inverse taper allows for more comfortable gripping by allowing the wrist to automatically go into dorsi flexion which results in permitting the fingers to flex more easily. The mobile ring and little finger metacarpals are allowed to oppose the thenar emminence thus bringing the ring and little fingers into more advantageous contact with the grip thereby making the holding of the grip less fatiguing.
