Problems solved by technology

The problem of face seal leakage is also compounded by the fact that FFRs are made in fairly common "small, medium and large" sizes and are often designed as a "one size fits all"

Embodiment 1

[0166] Use liquid silicone rubber with a hardness of 10 Shore A ( LSR 4310, Elkem Silicones USA) and ammonium bicarbonate blowing agent (Med4-4900, Nusil Technology LLC) were used for material preparation. The liquid silicone rubber used was a two-component platinum-catalyzed silicone elastomer that was hand mixed in a 1:1 ratio. Ammonium bicarbonate was measured at 1.5% by weight of the liquid silicone rubber mixture, then combined with it and hand blended.

[0167] Material shaping was performed using a knife coater. Blade coating is a process of forming a thin liquid coating on a continuous polymer web substrate by applying an excess of coating liquid, which is subsequently driven by a rigid blade against a rigid support web as the web advances Do the metering. The thickness of the coating depends mainly on the spacing or gap between the blade and the web, and the geometry of the gap (bevel, length, etc.). In this embodiment, the excess liquid silicone rubber and ammon...

Abstract

The present invention provides materials and methods for forming an interface between an appliance and living tissue using a foamed elastomeric material which contacts the tissue or similar surfaces.The elastomeric material is in the form of a durable and washable material that when applied to living tissue or similar surfaces displaces and flows in to non-conforming areas creating an air and / orwater tight seal that substantially returns to an original shape when removed from the contact surface. The appliance may also include structural elements designed to optimize comfort, compliance andseal achieved through minimizing the pressure variation along the contact surface of the therapy device.

Description

[0001] This application claims the benefit of, and claims priority to, US Provisional Application No. 62 / 557,587, filed September 12, 2017, and US Provisional Application No. 62 / 700,141, filed July 18, 2018 The provisional applications are each incorporated herein by reference in their entirety, including all tables, drawings, and claims. Background technique [0002] The following discussion of the background is merely provided to assist the reader in understanding the present invention, and is not an admission that it describes or constitutes prior art to the present invention. [0003] US Patents 5,343,878, 7,182,082 and 7,762,263 describe various devices intended to apply negative pressure on the outer surface of a patient's neck. A therapeutic appliance is generally provided having a surface configured to encapsulate an outer region of the larynx that covers a portion of the upper airway (as used herein, the term "larynx" refers to the area of ​​the neck extending general...
