Patents by Inventor Jiri G. Orlt

Jiri G. Orlt has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Apparatus for compensating for flow and pressure variances in pneumatic circuits
    Patent number: 5794614
    Abstract: An apparatus and method for facilitating the respiration of a patient are disclosed which are particularly useful in treating mixed and obstructive sleep apnea and certain cardiovascular conditions, among others, by increasing nasal air pressure delivered to the patient's respiratory passages just prior to inhalation and by subsequently decreasing the pressure to ease exhalation effort. The preferred apparatus includes a patient-coupled gas delivery device for pressurizing the patient's nasal passages at a controllable pressure, and a controller coupled with the delivery device having a pressure transducer for monitoring the nasal pressure and a microcontroller for selectively controlling the nasal pressure. In operation, the controller determines a point in the patient breathing cycle just prior to inhalation and initiates an increase in nasal pressure at that point in order to stimulate normal inhalation, and subsequently lowers the nasal pressure to ease exhalation efforts.
    Type: Grant
    Filed: June 7, 1996
    Date of Patent: August 18, 1998

  • Inspiratory airway pressure system controlled by the detection and analysis of patient airway sounds
    Patent number: 5259373
    Abstract: An apparatus and method for facilitating the respiration of a patient detects patient airway sounds and resolves these sounds into audio component bands whereupon an analysis is performed to produce a trend value. In response, a pressure action is determined using the trend value for controlling the pressure delivered to a patient for preventing the onset of obstructive apnea.
