Interface apparatus and combination and method
First Claim
1. Interface apparatus for use by a patient having a patient airway and for use with a mechanical ventilator having inspiratory and expiratory tubing, an intrapulmonary percussive ventilator having an output and an injection device coupled to the output of the intrapulmonary percussive ventilator and having an output, comprising a mixing device having a body providing a cone-shaped mixing chamber therein and having an outlet centrally disposed with respect to the cone-shaped mixing chamber for connection to the patient airway, said body having fittings in communication with the mixing chamber for connection to the inspiratory tubing and to the expiratory tubing of the mechanical ventilator, the body also having an injection port in communication with the mixing chamber for connection to the output of the injection device.

Abstract
Interface apparatus for use by a patient having a patient airway and for use with a mechanical ventilator having inspiratory and expiratory tubing. An intrapulmonary percussive ventilator having an output and an injection device coupled to the output of the intrapulmonary percussive ventilator and having an output. The interface apparatus comprises a mixing device having a mixing chamber therein and having an outlet adapted to be connected to the patient airway. The body has fittings in communication with the mixing chamber adapted to be connected to the inspiratory tubing and to the expiratory tubing of the mechanical ventilator. The body also has an injection port in communication with the mixing chamber adapted to be connected to the output of the injection device.

- 1. Interface apparatus for use by a patient having a patient airway and for use with a mechanical ventilator having inspiratory and expiratory tubing, an intrapulmonary percussive ventilator having an output and an injection device coupled to the output of the intrapulmonary percussive ventilator and having an output, comprising a mixing device having a body providing a cone-shaped mixing chamber therein and having an outlet centrally disposed with respect to the cone-shaped mixing chamber for connection to the patient airway, said body having fittings in communication with the mixing chamber for connection to the inspiratory tubing and to the expiratory tubing of the mechanical ventilator, the body also having an injection port in communication with the mixing chamber for connection to the output of the injection device.
- 5. Interface apparatus for use by a patient having a patient airway and for use with a mechanical ventilator having inspiratory and expiratory tubing, an intrapulmonary percussive ventilator having an output and an injection device coupled to the output of the intrapulmonary percussive ventilator and having an output, comprising a body providing a mixing device having a mixing chamber therein and having an outlet adapted to be connected to the patient airway, said body having fittings in communication with the mixing chamber and connected to the inspiratory tubing and to the expiratory tubing of the mechanical ventilator, the body also having an injection port in communication with the mixing chamber and connected to the output of the injection device, said mixing chamber in said body being in the form of a truncated conical mixing chamber, said body being provided with a flat base plate forming the base of the truncated conical mixing chamber, said outlet of the mixing chamber being centrally disposed with respect to the conical chamber.
- 7. A combination for use with a patient having a patient airway, a mechanical ventilator having inspiratory tubing and expiratory tubing and providing a selected tidal volume through the inspiratory tubing, an intrapulmonary percussive ventilator having an output, an injection device connected to the output of the intrapulmonary percussive ventilator and having an outlet and a mixing device coupled to the mechanical ventilator and to the intrapulmonary percussive ventilator, the mixing device comprising a body having a mixing chamber therein and having an outlet adapted to be connected to the patient airway, the body having an inspiratory port and expiratory port and an injection port in communication with the mixing chamber, means connecting the inspiratory port of the mixing device to the inspiratory tubing of the mechanical ventilator, means connecting the expiratory port of the mixing device to the expiratory tubing of the mechanical ventilator and means for coupling of the output of the injection device to the injection port of the mixing device.
- 12. A method for supplying pulmonary gases to a patient having an airway by the use of a mechanical ventilator providing cyclic low frequency tidal volumes and an intrapulmonary percussive ventilator supplying high frequency tidal volumes, the method comprising the steps of supplying low frequency tidal volumes from the mechanical ventilator, superimposing the higher frequency tidal volumes from the intrapulmonary percussive ventilator onto the low frequency tidal volumes of the mechanical ventilator to provide modulated tidal volumes and supplying the modulated tidal volumes to the airway of the patient.
