Abstract

Respiratory assembly for use in conjunction with a continuous positive airway pressure (CPAP) equipment is provided. The respiratory assembly includes a conduit coupler comprising a male member and a female member. The respiratory assembly also includes a disposable respiratory mask that defines a central opening therethrough that is sized to receive the male member. A gasket is positioned between the male member and the respiratory mask, the gasket encircling the central opening to provide a sealing thereto. A channel opening of one of the male member and the female member connects to a continuous positive airway pressure (CPAP) mask that couples to one or more of a patient's nare and mouth.

Claims (20)

1. A respiratory assembly for use in conjunction with a continuous positive airway pressure (CPAP) equipment, the respiratory assembly comprising:

a conduit coupler comprising a male member and a female member and a channel through the conduit coupler comprising an aperture defined in each of the male member and female member;

a fabric based, disposable respiratory mask defining a central opening therethrough that is sized to receive the male member, wherein the mask is configured to fully cover and enclose a nose and a mouth of a patient;

a first gasket positioned between the male member and the respiratory mask, the first gasket encircling the central opening to provide a sealing thereto; and

a nasal respiratory assembly comprising a post having a first end that is selectively affixed to a sheet configured to directly couple to an exterior portion of a patient's nostril, wherein the nasal respiratory assembly is directly connected attached to one of the conduit coupler or tubing disposed through the channel of the conduit coupler and wherein the nasal respiratory assembly is configured to be unattached to the interior of the patient's nostril.

2. The respiratory assembly of claim 1 , wherein the respiratory mask is configured for blocking at least 95 percent of particles of 0.3-micron size or greater.

3. The respiratory assembly of claim 1 , wherein the respiratory mask is a surgical mask.

4. The respiratory assembly of claim 1 , wherein the first gasket comprises an adhesive foam material.

5. The respiratory assembly of claim 1 , wherein the first gasket is formed of a stretchable elastomeric material.

6. The respiratory assembly of claim 1 , wherein at least one major surface of the first gasket comprises a peel-back glue membrane.

7. The respiratory assembly of claim 1 , wherein at least one major surface of the first gasket comprises a glue material.

8. The respiratory assembly of claim 1 , wherein respiratory assembly comprises a second gasket disposed between the female member and the respiratory mask, the second gasket encircling the central opening.

9. The respiratory assembly of claim 1 , wherein female member selectively engages with the male member.

10. The respiratory assembly of claim 1 , wherein both sides of the first gasket comprise an adhesive.

11. The respiratory assembly of claim 1 , wherein the central opening comprises a snap-on lid.

12. A respiratory assembly for use in conjunction with a continuous positive airway pressure (CPAP) equipment, the respiratory assembly comprising:

a respiratory mask defining an opening, wherein the respiratory mask is configured to fully cover and enclose a mouth and a nose of a patient;

a conduit coupler forming a substantially airtight seal around the opening of the respiratory mask, wherein the conduit coupler comprises:

a male member and a female member, each defining an aperture for a conduit to fit therethrough, wherein a sleeve of the male member is configured to pass through the opening of the respiratory mask to selectively engage with the female member, a gasket provided between the female member and the respiratory mask such that the gasket forms a substantially airtight seal between the sleeve of the male member and the opening when the male member selectively engages with the female member;

wherein a connector end of the female member is in fluid communication with a channel opening of a fluid source; and a nasal respiratory assembly having a portion a post having a first end that is selectively affixed to a sheet that is configured to directly couple to a patient's nostril, wherein the nasal respiratory assembly is directly connected attached to the conduit coupler and wherein the nasal respiratory assembly is configured to be unattached to the interior of the patient's nostril.
