Abstract: Presented are manual ventilator systems, methods for making/using such ventilator systems, and clamshell, accordion-style ventilators operable by a lone operator. A ventilator device includes first and second panels pivotably attached together in a clamshell configuration. Each panel has an inlet port, an outlet port, and an internal channel that fluidly connects the inlet and outlet ports. A one-way valve is fluidly connected to the first panel’s outlet port and restricts airflow therethrough in one direction. Another one-way valve is fluidly connected to the second panel’s inlet port and restricts airflow therethrough in an opposite direction. A concertinaed bellows is fluidly connected to the first panel’s outlet port and the second panel’s inlet port. The bellows is sandwiched between and attached to the two panels such that pivoting the panels away from each other expands and fills the bellows whereas pivoting the panels towards each other compresses and evacuates the bellows.

Abstract: A portable, collapsible hyperbaric chamber. A toroidal inflatable skeleton provides initial structural support for the chamber, allowing the attendant and/or patient to enter the chamber. Oval hatches mate against bulkhead rings, and the hyperbaric chamber is pressurized. The hatches seal against an o-ring, and the internal pressure of the chamber provides the required pressure against the hatch to maintain an airtight seal. In the preferred embodiment, the hyperbaric chamber has an airlock to allow the attendant to enter and exit the patient chamber during treatment. Visual communication is provided through portholes in the patient and/or airlock chamber. Life monitoring and support systems are in communication with the interior of the hyperbaric chamber and/or airlock chamber through conduits and/or sealed feed-through connectors into the hyperbaric chamber.
