Abstract: An oral irrigator handle through which fluid flows to a tip is described. Fluid flows from a fluidically connected hose to the tip during irrigate mode, and fluid flow may be interrupted by selecting a pause mode. The handle includes a mechanically controlled actuator for selecting the pause mode. The actuator may be operably connected to a shuttle valve that is positioned to block fluid flow to the tip during pause mode but not during irrigate mode. The handle may also include a swivel assembly. The swivel assembly prevents rotational movement of either the handle or the hose from being transmitted to the other, such that rotation of the handle will not affect the position of the hose.

Abstract: A manual patient ventilation system includes a breathing bag manually compressed by a clinician to ventilate a patient via a patient interface device, a gas supply system supplying fresh gas to the breathing bag at a fresh gas flow rate, a pressure sensor measuring a patient airway pressure (PAW) throughout a compression and release cycle of the breathing bag by the clinician, a fresh gas controller comprising a processor, and a manual ventilation control module executable on the processor by the fresh gas controller. The manual ventilation control module includes instructions executable to receive the Paw measurements and determine a fresh gas flow rate based thereon. The gas supply system is then controlled to supply the fresh gas flow rate into the breathing circuit.

Abstract: Injury-specific resistive exoskeleton devices and iris-based mechanisms utilized therein. The devices assist those currently in rehabilitation or those who have lost partial or all motion to specific muscles. The device can be used for directly driving a limb or providing resistance to partially impaired muscles. For example, the device can provide a resistive force during contraction of an affected/injured muscle and release the resistive force during contraction of an unaffected/healthy muscle. The iris-based joint mechanism generally includes a hub, an iris mechanism, and a plurality of teeth disposed therebetween. When the teeth are engaged with the hub, the mechanism is locked and the servo outputs a rotational force that affects rotation of the user's limb. When the teeth are disengaged with the hub, the mechanism is unlocked and the user has full range of motion of the underlying hinge joint.
