Abstract
A system for delivering medical gas, such as supplemental oxygen, to a subject includes a positioner and a diffuser. The positioner includes a positioning wall with an aperture that receives and may couple to a proximal portion of the diffuser. The system may also include a pillowcase with one or more fasteners that hold the positioner and a diffuser coupled thereto at a desired location and orientation over a pillow where a subject who is to receive medical gas will place their head. The pillowcase may receive two positioners and associated diffusers. Methods of administering medical gas and methods for maintaining medical gas delivery systems are also disclosed.
Claims20
A medical gas delivery system, comprising:
- a positioner including:
- a positioning wall with a concave front surface defining a recess;
- and
- an aperture through the positioning wall;
- and
- a diffuser including:
- a proximal portion shaped to be received by the aperture and defining an inlet of the diffuser through a proximal end of the proximal portion;
- an intermediate portion adjacent to a distal side of the proximal portion;
- and
- a distal portion adjacent to a distal side of the intermediate portion with a diameter that exceeds a diameter of the proximal portion, a distal end of the distal portion defining a delivery face of the diffuser.
A method for delivering a medical gas to a subject, comprising:
- coupling a proximal portion of a diffuser to a positioning wall of a positioner;
- placing the positioner at a first location on an upper surface of a pillowcase on which a head of the subject will be placed so as to place a delivery face of the diffuser adjacent to a second location on the upper surface where the head of the subject will be placed;
- orienting the delivery face of the diffuser toward the second location;
- and
- removably securing the positioner to the first location.
A diffuser for medical gas delivery, comprising:
- a use indicator that provides a perceptible indication that a useful life of the diffuser has ended.
