Definitions

  • This disclosure relates to systems for delivering medical gases, such as supplemental oxygen, to a subject. More specifically, this disclosure relates to systems that employ pillows to deliver medical gases, including pillows and systems that are designed to be assembled with a surface of a pillow or another surface on which a subject may rest their head. Such a system includes a positioner that positions the head and face of the subject in a desired orientation and a diffuser that delivers medical gas to the face of the subject. Methods for delivering medical gases are also disclosed.
  • supplemental oxygen helps subjects who suffer from sleep apnea, acute bronchitis, asthma, heart conditions, chronic obstructive pulmonary disease (COPD), dementia, Alzheimer’s disease, and other disorders achieve more stable, restful states of sleep than those subjects typically experience without supplemental oxygen.
  • COPD chronic obstructive pulmonary disease
  • a variety of apparatuses, including conventional oxygen delivery systems, may be used to provide hypoxic patients with supplemental oxygen as they sleep.
  • Nasal cannulas may also be ineffective for delivering supplemental oxygen to subjects who suffer from upper respiratory tract infections (e.g., a common cold, influenza, sinus infections, etc.) and to subjects who suffer from nasal abnormalities (e.g., a deviated septum, etc.).
  • upper respiratory tract infections e.g., a common cold, influenza, sinus infections, etc.
  • nasal abnormalities e.g., a deviated septum, etc.
  • An embodiment of a medical gas delivery system of this disclosure may include a diffuser and a positioner.
  • the diffuser may include a base that supports the diffuser on a surface (e.g., a surface on which a subject rests their head, such as a pillow, etc.), walls that define a recess, an inlet at one end of the receptacle, and a delivery face at an opposite end of the recess.
  • a gas delivery tube may couple to the diffuser adjacent to the inlet.
  • the walls of the diffuser may taper outwardly from the side of the diffuser on which the inlet is located to the side of the diffuser on which the delivery face is located.
  • the walls of the diffuser may impart the diffuser with a size and a shape that enable gas to be delivered efficiently and effectively to the face of a subject.
  • Use of the diffuser includes providing gas flow from a source, through the gas delivery tube, through the inlet, into the recess, and out of the delivery face.
  • the positioner may include a base that supports the head positioner on the surface, as well as an orienting surface that receives a back of a subject’s head in a manner that orients the subject’s head on the surface and positions the subject’s face toward the delivery face of the diffuser.
  • One or both of the diffuser and the positioner may include a coupler.
  • a coupler may hold the base of its respective component (i.e., the diffuser or the positioner) in place on the surface that supports the component.
  • the coupler may comprise a strap that extends around the pillow or other cushion to secure the component to it.
  • the coupler may comprise a so-called “touch fastener” (e.g., the hook elements of Velcro, etc.) that engages another touch fastener, elastic, or a fabric (e.g., a soft, fuzzy fabric that comprises the loop elements of Velcro, etc.) on the surface (e.g., a pillowcase on a pillow, etc.).
  • the coupler may comprise a pocket associated with (e.g., on, in, etc.) the surface.
  • the medical gas delivery system may also include a cover.
  • the cover may comprise a pillowcase.

  • a cover may be positioned over the positioner, the diffuser, and the surface. Positioning the cover may include positioning a vent through the cover over or adjacent to the delivery face of the diffuser to enable gas to flow freely from the delivery face of the diffuser to a face of the subject.
