  • Endotracheal tube with inflatable cuffs
    Patent number: 4976261
    Abstract: An endotracheal tube for artificial ventilation employs a primary cuff and a secondary cuff for locating and positioning the tube in the trachea of a patient. The secondary cuff employs a balloon sleeve which is located in close proximity to the distal end of the tube. The secondary balloon sleeve is sealed against the tube in a reverse folded configuration. The tube wall includes a number of lumens which may be employed for various auxiliary functions.

  • Multi-frequency jet ventilation technique and apparatus
    Patent number: 4838259
    Abstract: Respiration therapy is accomplished by generating pulses of inhalation gas for delivery to a patient. The inhalation gas pulses may be generated by entraining humidified low pressure gas with pulses of high pressure entrainment gas. The pulses of entrainment gas may be of variable frequency, duration and duty cycle and are produced by modulating the flow of a highly pressured gas with a solenoid operated valve.
