Abstract
Disclosed herein are embodiments describing nonrebreather facemasks for efficiently and comfortably delivering oxygen to patients. One embodiment describes a cup-shaped pliable facemask that is suited to cover and seal a patient’s nose, mouth, and cheeks within the cup-shaped facemask. Certain other embodiments describe an inlet tube outwardly extending from the facemask at an angle in line with the pathway of a patient’s nostrils to better provide oxygen directly into a patient’s nose. Other embodiments envision varying facemask’s stiffness for improved comfort and sealing against the patient’s face. While other embodiments envision a reduction in dead space of a facemask when worn by a patient to improve oxygen efficiency used by the patient.
Claims20
A reduced dead space adult facemask comprising:
- a pliable adult sized facemask cup that is essentially defined by a nose covering region, a mouth covering region, two cheek coving regions and a perimeter, the perimeter essentially defined by a nose bridge rim, two cheek rims and a chin rim,
- the nose covered region shaped to closely conform to an adult human nose, the mouth covering region configured to be in front of an adult human mouth, the cheek covering regions configured to at least partially contact corresponding sides of adult human cheeks;
- an inlet tube outwardly extending from the adult facemask, the inlet tube generally defined by a passageway that leads through a distal aperture and nose aperture in the facemask,
- a facemask cup volume that is essentially defined by a maximum amount of water the facemask cup can hold, the facemask cup volume less than 6.1 in3.
A pliable adult facemask comprising:
- a facemask cup defining a convex shaped outer surface, an inner surface of the facemask cup configured to cover a mouth of a wearer via a mouth covering region of the facemask cup and nostrils of a wearer via a nose covering region of the facemask cup;
- an inlet tube extending from the facemask outer surface to a distal tube aperture, the inner surface is in communication with the distal tube aperture along the inlet tube via a proximal aperture in the facemask,
- at least 80% of an interior portion of the facemask cup is within one eighth of an inch from a human face.
A pliable adult facemask comprising:
- a facemask cup that is essentially defined by a nose covering region, a mouth covering region, two cheek coving regions and a perimeter, the perimeter essentially defined by a nose bridge rim, two cheek rims and a chin rim,
- the nose covered region shaped to closely conform to an adult human nose, the mouth covering region configured to be in front of an adult human mouth, the cheek covering regions configured to at least partially contact a corresponding side of an adult human cheek;
- an inlet tube outwardly extending from the adult facemask, the inlet tube generally defined by a passageway that leads through distal aperture and nose aperture in the facemask;
- and
- means for actively reducing dead space of the facemask cup.
