  • Tracheal gas insufflation bypass and phasic delivery system and method
    Patent number: 6269813
    Abstract: Tracheal gas insufflation (TGI) therapy is performed by a bypass valve and a controller which control a flow of TGI gas to a TGI catheter inserted into an endotracheal tube in the tracheal of a patient. The bypass valve is activated into a pass-through state to admit the TGI gas into the catheter and into a bypass state to divert the TGI gas from the TGI catheter. Potentially dangerous over-pressure may be sensed and the TGI gas flow terminated, but then quickly resumed after the over-pressure condition passes. Selectively applying and diverting the TGI gas allows phasic TGI therapy to be performed using heated and humidified gas and also allows the heat and humidity levels of the TGI gas to be maintained during continuous TGI therapy.

  • Gas supplying and substance suctioning relative to a patients trachea
    Patent number: 6227197
    Abstract: A gas insufflation and suction apparatus is provided for communication with a patient's trachea. The apparatus includes a gas catheter and a suction catheter. When supplying a suitable gas having a desired oxygen concentration to the patient, an output end of the gas catheter is moved past a Y-connector through a T-member into the patient's trachea. After removal of the gas catheter from the patient 's trachea, mucus or other substances can be removed from the patient using the suction catheter. With the gas catheter in its standby position, the suction catheter is moved past the Y-connector through the T-member and located in a desired position in the patient's trachea.
