The present invention discloses an isolation system, comprising a flexible, portable, disposable membrane with no rigid structures. The membrane inflates from a contracted state having a small form-factor for storage to an inflated state for use. The membrane has an opening on one side defining a chamber within, with the opening having a sealing member that when closed, seals off the chamber. The membrane includes a first port for ingress of gas into the chamber a second port for egress of exhaust gas via an associated exhaust filter assembly, with the second port intrinsically functioning as a passive pressure regulator.

Isolation system

The cushion has a contoured base with a layer of resilient cushion foam thereover. The cushion foam is of uniform thickness over a substantial part of the base and is suitably covered. The shape is such that the buttocks of the seated person are clasped positioned rather than supported. A recess is provided under the ischia, under the trochanters, and beneath the sciatic nerves to limit the local pressure. In one configuration, these recesses may contain air bladders which are inflated by body motion against a back bladder in the cushion. In another embodiment, the various bladders may be sequentially pressurized to shift the bearing areas under the buttocks of the seated user in order to periodically lift the user for stimulating blood circulation.
