Abstract
A unitary breathing head device for administering intermittent percussive ventilation to a patient having an airway and for use with an IPV device (16) having a source of continuous gas flow and having a source of pulsed gases comprising a combination injector and exhalation valve assembly (12) comprising a main body (26) having an airway port for communication with the airway of the patient and having proximal (27) and distal extremities (28) and a flow passage (29) extending from the proximal extremity to the distal extremity. The main body has a depending portion forming a plenum chamber (82) in communication with the flow passage in the main body. A nebulizer (13) is removably secured to the depending portion of the main body and has a nebulizer chamber in communication with the plenum chamber. The depending portion of the main body and the nebulizer form a handle adapted to be gripped by the hand of the patient holding the breathing head assembly.
Claims (13)
1. Apparatus for administering intermittent percussive ventilation to a patient having an airway, comprising an intrapulmonary percussive ventilation device for providing sources of gases under continuous flow and cyclic flow and a unitary breathing head assembly, the assembly comprising an elongate main body having proximal and distal extremities and having flow passages extending from the proximal extremity to the distal extremity, the main body having an airway port adapted to be placed in communication with the airway of the patient and in communication with the flow passage of the main body, an expiratory port carried by the main body proximally of the airway port, a valve seat formed in the main body and circumscribing the flow passages in the main body, an injector body slidably mounted in. the flow passage of the main body and having proximal and distal extremities, the injector body having its distal extremity movable into and out of engagement with the valve seat, the injector body having a venturi-like passageway extending therethrough from the proximal extremity to the distal extremity, a diaphragm carried by the main body coupled to the injector body having a retracting memory for retaining the injector body in a retracted position with respect to the valve seat,.the main body having a depending portion forming a plenum chamber in communication with the flow passage in the main body, a nebulizer having a nebulizer bowl providing a nebulizing chamber therein, cooperative mating means for removably securing the nebulizer body to the depending portion of the main body and establishing communication between the nebulizing chamber and the plenum chamber in the depending portion of the main body, and tubing coupling the intrapulmonary percussive ventilation device to the nebulizer and tp the main body for supplying a continuous flow of gas to the nebulizer and a pulsatile flow gas to the main body.
2. Apparatus as in Claim 1 wherein said depending portion has an ambient entrainment gate therein for mixing ambient air with the aerosol in the plenum chamber.
3. Apparatus as in Claim 1 for use with a horizontal support surface wherein said nebulizer is provided with a depending skirt having a lower extremity lying in a horizontal plane, said skirt having dimensions whereby the breathing head assembly is supported in a vertical position when the lower planar surface is resting on the horizontal support surface.
4. Apparatus as in Claim 1 wherein said main body has a lower surface which is inclined downwardly and rearwardly so that liquid condensing within the passageway in the main body and in the venturi-like passageway will flow by force of gravity through the plenum chamber into the nebulizer chamber of the nebulizer bowl.
5. Apparatus as in Claim 1 wherein said nebulizer bowl is provided with liquid therein, a shroud mounted in the bowl and extending above the liquid, a diffractor surface carried by the shroud, capillary means in the shroud for delivering liquid from the liquid in the bowl and causing it to impinge against the deflector plug to provide an aerosol emitted from the shroud, and a cape mounted over the diffractor surface and having a depending skirt, said depending skirt serving to control the dispersion of the aerosol being emitted from the shroud.
6. Apparatus as in Claim 5 wherein said cape is removable so that it can be interchanged.
7. Apparatus as in Claim 1 further including switch means including a push button carried by the depending portion adapted to be engaged by a finger of the hand holding the breathing head device for controlling the flow of pulsatile gases to the main body.
8. A unitary breathing head device for administering intermittent percussive ventilation to a patient having an airway and for use with an IPV device having a source of continuous gas flow and having a source of pulsed, gases comprising a combination injector and exhalation valve assembly comprising a main body having proximal and distal extremities and a flow passage extending from the proximal extremity to the distal extremity, said main body having an airway port carried by the main body at the distal extremity thereof and in communication with the flow passage in the main body, an expiratory port carried by the main body proximal of the airway port, a valve seat formed in the main body and circumscribing the flow passage in the main body, an injector body slidably mounted in the flow passage of the main body and having proximal and distal extremities and having its distal extremity movable into and out of engagement with the valve seat, the injector body having a venturi-like passageway extending therethrough from the proximal extremity to the distal extremity, a diaphragm carried by the main body and coupled to the injector body, the main body having a depending portion forming a plenum chamber in communication with the flow passage in the main body, the breathing head assembly also comprising a nebulizer, the nebulizer comprising a nebulizer bowl having a nebulizer chamber therein, cooperative mating means for removably securing the nebulizer bowl to the depending portion of the main body and establishing communication between the nebulizer chamber and the plenum chamber, the depending portion of the main body and the nebulizer forming a handle adapted to be gripped by the hand of the patient holding the breathing head assembly during use, a fitting connected to the nebulizer which is adapted to be supplied withe a continuous flow of gas from the IPV device and a fitting conneced to the main body which is adapted to be supplied with pulsed gases from the IPV device for delivery to the diaphragm and to the injector body.
9. A breathing head assembly as in Claim 8 for use with a horizontal support surface wherein said nebulizer is provided with a depending skirt, a surface lying in a horizontal plane for supporting the breathing head assembly in an upright position when the skirt of the nebulizer is resting upon the horizontal support surface.
10. An assembly as in Claim 8 further including switch means carried by the depending portion of the main housing for controlling the supply of pulsed gases to the main body.
11. An assembly as in Claim 8 wherein said diaphragm has a retracting memory whereby the injector body is yieldably maintained out of engagement with the valve seat.
12. An assembly as in Claim 8 wherein said nebulizer has a liquid therein and nebulizing means within the bowl for aspirating liquid from the bowl and creating an aerosol containing liquid particles therein.
13. An assembly as in Claim 12 further including a cape having a depending skirt overlying the nebulizing means.
