Supplemental air diffusion devices, kits and methods

摘要

A supplemental air diffusion device is shaped and configured to be attached to the body or clothing of a patient below the head and deliver supplemental air toward the mouth and nose of the patient. The supplemental air diffusion device includes a frustroconicoidal air diffusion body that has a smaller inlet opening at an inlet end and an enlarged diffusion opening at a diffusion end. An air inlet stem is integrally attached to the air diffusion body and includes a plurality of ribs and/or recesses for releasably locking a female connector of an air supply hose over the inlet stem. A pair of spaced-apart slits are provided through a flange extending laterally from an outer surface of the air diffusion device. Initially separate accessory patient attachment clamps are looped through the slits and provide for releasable attachment of the air diffusion device to a patient's clothing. A kit may include an air diffusion device, one or more accessory patient attachment clamps, and an air supply hose for establishing fluid communication between the air diffusion device and an air supply.

主权项

1. A device for delivering supplemental oxygenated air toward a person's face without covering the person's nose and mouth, comprising:
a supplemental oxygenated air diffusion body made from polymer, metal, or, rigid material and being frustroconicoidal so as to define an interior passageway extending between an inlet end and an outlet end of the diffusion body, the outlet end having an enlarged diffusion opening that is larger than an inlet opening at the inlet end; a rigid inlet stem, in fluid communication with the inlet opening, integrally attached to and non-bendably extending from the inlet end of the diffusion body, the inlet stem having a length, diameter, and taper that facilitate insertion into a standard female coupling end of an oxygenated air supply hose; one or more ribs or recesses formed on an outer surface of the inlet stem and adapted to mechanically engage an inner surface of the standard female coupling end of the oxygenated air supply hose; one or more rigid flanges integrally formed with and extending laterally from an exterior surface of the diffusion body; one or more holes or slits formed in the one or more rigid flanges; and one or more accessory patient attachment devices adapted for releasable attachment to the one or more rigid flanges of the diffusion device, wherein each patient attachment device includes a strap looped through one of the one or more holes or slits and a spring loaded clamp adapted for removable attachment to clothing.
