  • Medical ventilator device parametrically controlled for patient ventilation
    Patent number: 4448192
    Abstract: A ventilator which accommodates to a patient's efforts in breathing and to his change in respiratory requirements is provided by a system with a novel control law. The novel control law determines a target ideal pressure-volume wave-form which characterizes the patient's respiratory requirements; this waveform is constantly modified and corrected during the course of ventilator operation to enable the patient to breathe with minimum ventilation opposition, or fighting.

  • Glyco/proteinaceous materials derivable from beef liver and other tissues useful for the treatment of toxic and allergic conditions
    Patent number: 4169139
    Abstract: Mucoprotides (i.e., complex compounds of protein with carbohydrates and carbohydrate derivatives) derived from animal tissues, for example, mammalian liver by a succession of extractive steps including treatment with acetone to produce three layers or phases of which the upper two are separated and further processed, the bottom layer being discarded. The retained layers are further treated to purify and de-antigenize them. The product is useful for treatment of allergic conditions, as a detoxicant and for treatment of narcotics addiction.
