Respiratory therapy device having standard and oscillatory PEP with nebulizer
First Claim
1. A respiratory therapy device comprisinga housing having a first port to receive a person'"'"'s exhaled breath, a second port, and a third port,a non-oscillatory positive expiratory pressure (PEP) device coupled to the second port,an oscillatory PEP device coupled to the third port,a manually operable valve member movable between a first position blocking the third port and allowing the person'"'"'s exhaled breath to flow to the non-oscillatory PEP device through the second port and a second position blocking the second port and allowing the person'"'"'s exhaled breath to flow to the oscillatory PEP device through the third port, wherein the non-oscillatory PEP device includes a tube, a knob, and a cylindrical stem extending from the knob, the cylindrical stem having a hollow central passage, an open end, and a plurality of apertures communicating with the hollow central passage, the stem being situated adjacent the tube and being movable to select how many of the plurality of apertures of the cylindrical stem are exposed to an interior region of the tube thereby to change a flow resistance of the non-oscillatory PEP device, andan adjuster coupled to the knob, the adjuster engaging a member of the oscillatory PEP device to adjust a characteristic of oscillation of the oscillatory PEP device.

Abstract
A respiratory therapy device has both a standard positive expiratory pressure (PEP) device and an oscillatory PEP device packaged together. A manually operable member is movable to select which of the standard and oscillatory PEP device is placed in communication with a patient'"'"'s airway. A nebulizer connector may also be provided for connection of a nebulizer.
