Abstract: This disclosure provides an oxygen delivery and reclamation system that supplies breathable oxygen-enriched gas to one or more users in a chamber. The one or more users receive oxygen at specified oxygen level setpoints. Exhalation air from the one or more users may be purged from the breathing loop using one or both of a recycle pump and an electronically actuated valve. Exhalation air in a purge line and optionally chamber air pulled from the chamber may be recycled using an oxygen concentrator. The oxygen concentrator generates oxygen-enriched gas and oxygen-depleted gas, where the oxygen-enriched gas may be delivered back to one or more users in the chamber.

Abstract: A system for actuating a volume and/or pressure-controlled manual ventilator including a manual ventilator, a storage case, and an actuating mechanism. The manual ventilator includes a compressible body, an output one-way valve at an output end, and an input one way valve at an input end. The storage case includes an inner housing surface configured to accommodate the manual ventilator. The actuating mechanism includes a power unit mechanically coupled to a linear rod mechanism and one or more applicator pads mechanically coupled to the linear rod mechanism and proximal to the compressible body. The linear rod mechanism is configured to convert a rotating motion of the power unit into an axial movement of the linear rod mechanism. The actuating mechanism is configured to apply pressure to the compressible body of the manual ventilator via the one or more applicator pads such that a volume of the compressible body is deflated.

Abstract: An exercise with oxygen therapy (EWOT) apparatus for rejuvenating oxygen- depleted cell tissue and simulating high altitude oxygen conditions. The EWOT apparatus includes a first cylindrical bladder for providing oxygen -enriched air and a second bladder for providing lower-purity hypoxic air. The first bladder is retained within an open, lightweight rectangular-shaped frame having vertical frame members. An air supply source provides the oxygen-enriched and hypoxic air to the first and second bladders, respectively. A control switch, which can be manually and/or programmed to automatically operate, selectively delivers the oxygen-enriched and/or hypoxic air to a breathing mask worn by a user while exercising on exercise equipment. The first bladder includes a plurality of weights which provide a positive pressure to the air therein. The cylindrical first bladder is attached to the vertical frame members with slidable rings and expands and collapses in a vertical direction when being filled or during use, respectively.

Abstract: A face mask that can be used for the ventilation of patients such as in bag-valve-mask resuscitator systems is provided. The face mask can be used to form a tight seal with the patient's mouth and nose, while also creating an open airway. The face mask includes a jaw (chin)-lifting member that can be used to position the patient's head in a tilted position. The invention also encompasses bag-valve mask resuscitator systems and methods for using bag-valve mask resuscitators in the ventilation of patients. In one embodiment, the bag-valve mask resuscitator is placed so that the bag is positioned over the midline of the face of the patient.

Abstract: A respiratory ventilator is provided. The ventilator comprises a bellows configured to be compressed to deliver a selected tidal volume to a patient. A connecting rod is operably connected to the bellows to compress the bellows by a selected stroke distance that corresponds to the selected tidal volume. A crank arm has an elongated slot into which a pin extends to connect the connecting rod to the crank arm. A control wheel is for selectively adjusting an effective crank arm length. The effective crank arm length directly corresponds to the stroke distance of the connecting rod. The control wheel has a slot into which the pin extends. Selective rotation of the control wheel relative to the crank arm urges the pin to move along an elongated slot of the crank arm toward and away from a drive axis to selectively adjust the effective crank arm length.
