US Patent 11542980 Universal quick-release anchor member

A universal quick-release anchor member includes a flexible base seal member comprising non-porous resilient material. The base seal member is configured to engage an external reference surface and form a substantially airtight seal therewith that defines a controlled pressure zone. A vent port extends through the anchor member. A vent port closure member is disposed proximate to a vent port upper end. The vent port closure member is biased to move from a closed position to an open position. The closed position includes the vent port closure member being arranged to block the vent port upper end and prevent the passage of air through the vent port. The open position includes the vent port closure member being arranged to unblock the vent port upper end and allow the passage of air through the vent port.
