摘要： An engine is connected to the upper end of a drive shaft housing and a work head with a string trimmer or blower or both is operatively connected to the lower end of the drive shaft housing and is rotatably driven by an engine rotating a drive shaft inside the drive shaft housing and connected to the working head. The drive shaft housing is rigidly connected to the working head and may be rotated about its longitudinal axis relative to the engine in any desired amount of rotation, but the preferred degree of rotation is 135° to move the working head from a trimming position with the rotating trimmer string in a horizontal position to an edging position with the rotating trimmer string in a vertical position and with the working head being displaced to the operator's right side for better viewing and control and operator comfort. In one embodiment, a gear driven crank handle is rigidly connected to the drive shaft housing and is itself rotated 135° as the drive shaft housing is rotated 135° to place the handle in a position that is comfortable to use. Further, the amount of air flowing through the blower is regulated by an air outlet regulating valve and a separate air intake regulating valve.

摘要： A breathing apparatus includes a supply tube configured to provide a supply of air. A first and second nasal interface each include a generally spherical member having a respective projection configured to be at least partially received within a respective nasal passage of a user, and are independently movable relative to the housing. A valve is disposed between the fluid chamber and an exhaust passage for selectively allowing air to be exhausted from the fluid chamber via the exhaust passage. A diaphragm, coupled to a bias chamber, is also coupled to the valve for moving the valve between the open position and the closed position. Bias pressure within the bias chamber is regulated, at least in part, by a loading fluid impedance and a venting fluid impedance.

摘要： An nCPAP device including a generator body defining first and second fluid flow circuits each including a tube and first and second nozzles. The tube defines a passageway forming an axial centerline. The first and second nozzles are associated with the tube and each defines an inlet and an outlet. The inlets are open to a fluid supply, whereas the outlets are open to the passageway. Each nozzle is adapted to emit a fluid jetstream from the outlet along a flow direction axis. The nozzles are arranged such that the flow direction axes are non-parallel relative to each other and relative to the axial centerline. This configuration readily induces vortex shedding during an expiratory phase, thus facilitating jet fluid flow disruption and reducing a patient's work of breathing.

摘要： Various embodiments of a breath-activated nebulizer with flow-based fluidic control and related methods of using such a nebulizer are disclosed. The nebulizer may include a body comprising a reservoir for holding medication, a nozzle for emitting a jet of pressurized gas, and a fluid conduit in communication with the reservoir for delivery of the medication proximate the jet to produce an aerosol of medication. The nebulizer may also include a nebulizer outlet in communication with the body for delivery of the aerosol to a patient, an entrainment passage for providing entrainment flow from atmosphere during inhalation by the patient, and a control conduit in fluid communication with the fluid conduit for delivery of a control gas to the fluid conduit to prevent the delivery of the medication proximate the jet. In some exemplary embodiments, the control conduit may comprise a gas passage proximate the entrainment passage to allow the control gas to flow across the entrainment passage. During the inhalation by the patient, the entrainment flow through the entrainment passage may substantially prevent the control gas from flowing across the entrainment passage so as to interrupt the delivery of the control gas to the fluid conduit.
