Abstract
Various embodiments of a patient interface device, such as a mask, nasal pillow, or nasal cannula, that includes an adhesive layer provided on a surface thereof that is structured to temporarily bond to the skin of a user of the patient interface device. The adhesive layer may include a bonding agent, such as a polymer gel, having a residual extraction force of between about 50 grams and about 200 grams.
Claims12
A nasal cannula, comprising;
- one or more nasal inserts for delivering a fluid to a nasal passageway of a user;
- at least one attachment panel;
- and
- an adhesive layer provided on the at least one attachment panel and being adapted to temporarily bond to the skin of such a user, the adhesive layer comprising a polymer gel, wherein the nasal cannula includes a fluid delivery tube in fluid communication with the one or more nasal inserts, and wherein the fluid delivery tube is inserted through one or more apertures provided in the at least one attachment panel, wherein the one or more apertures each have a first diameter and the fluid delivery tube has a second diameter that is smaller than the first diameter, whereby the fluid delivery tube is free to move relative to the at least one attachment panel within the one or more apertures prior to being temporarily bonded to the skin of such a user.

A nasal cannula, comprising;
- one or more nasal inserts for delivering a fluid to a nasal passageway of a user;
- at least one attachment panel;
- and
- an adhesive layer provided on the at least one attachment panel and being adapted to temporarily bond to the skin of such a user, the adhesive layer comprising a polymer gel, wherein the nasal cannula includes a first fluid delivery tube and a second fluid delivery tube in fluid communication with the one or more nasal inserts, wherein the at least one attachment panel comprises a first attachment panel and a second attachment panel connected to one another by a connecting strip, and wherein the first fluid delivery tube is inserted through a first aperture provided in the first attachment panel and the second fluid delivery tube is inserted through a second aperture provided in the second attachment panel, wherein the first and second apertures each have a first diameter and the fluid delivery tube has a second diameter that is smaller than the first diameter, whereby the first fluid delivery tube is free to move relative to the first attachment panel within the first aperture and the second fluid delivery tube is free to move relative to the second attachment panel within the second aperture.
1 more element
A nasal cannula, comprising;
- one or more nasal inserts for delivering a fluid to a nasal passageway of a user;
- a fluid delivery barrel in fluid communication with the one or more nasal inserts, wherein the one or more nasal inserts extend outwardly and away from one or more outer surfaces of the fluid delivery barrel;
- a first fluid delivery tube connected to a first end of the fluid delivery barrel and a second fluid delivery tube connected to a second end of the fluid delivery barrel opposite the first end, the first and second fluid delivery tubes being in fluid communication with the one or more nasal inserts through the fluid delivery barrel;
- and
- an adhesive layer provided on the one or more outer surfaces of the fluid delivery barrel and being adapted to temporarily bond to the skin of such a user, the adhesive layer comprising a polymer gel, wherein the adhesive layer further includes a coating layer formed by co-curing the polymer gel with at least one layer of a primer material.
