Pressure regulating systems for expandable insertion devices
First Claim
Patent Images
1. An orifice insertion device, comprising:
- an insertion element including a feeding tube;
an expandable element configured to seal an orifice, the expandable element including an interior region at a first pressure, the expandable element circumferentially attached to the insertion element and coupled to the feeding tube;
a pressure regulation system coupled to the insertion element, the pressure regulation system including at least one pressure valve, the pressure regulation system configured to provide a medium to the interior region of the expandable element via the feeding tube of the insertion element responsive to the at least one pressure valve, the pressure regulation system having a second pressure proximate the at least one pressure valve; and
a pressure release mechanism coupled to the pressure regulation system, the pressure release mechanism configured to manually adjust a current pressure in the expandable element responsive to a user,where the pressure release mechanism includes a release pin coupled to the at least one pressure valve and a resilient restoring member coupled to the release pin, the resilient restoring member including an elastic membrane, activation of the resilient restoring member decreasing the current pressure in the expandable element, andwhere the at least one pressure valve is configured to open to at least a design flow rate when a difference between the first pressure and the second pressure is greater than a threshold level.

Abstract
Earpieces and expandable insertion devices are provided. An earpiece includes an ambient sound microphone (ASM); an ear canal microphone (ECM); an ear canal receiver (ECR); and an inflatable sealing section. The sealing section includes at least one pressure valve. The at least one pressure valve opens when the pressure in the sealing section is greater than an ambient pressure.
