  • Patent number: 5472403
    Abstract: The automatic injection device comprises two syringes, one for injecting a measured quantity of radionuclide and a second for injecting a saline solution for flushing the intravenous tubing through which the radionuclide has been delivered. Each of these syringes is driven by a motor which compresses the plunger of the syringe causing it to inject its contents. The motors receive an activation signal from a computer controller which initiates the injection sequence upon receipt of a trigger signal which is provided either by a separate seizure detection computer, by activation by the patient who recognizes an aura indicative of an imminent seizure, or by activation by medical personnel observing the patient. The computer implements a delay cycle to permit verification of the trigger to avoid initiating the injection sequence in the event of false alarms.

  • Patent number: 5456264
    Abstract: Inspiratory flow limitation (IFL) is involved in the pathophysiology of sleep-related breathing disorders. Since the definition of flow-limited cycle is based on a dissociation between flow and respiratory efforts, identification of IFL requires upper airway or intrathoracic pressure measurements. We examined the feasibility and accuracy of the analysis of the flow-volume loop of a tidal breath in identifying IFL. The tidal volume was obtained by integration of the instantaneous airflow signal, and the flow-volume loop was reconstructed for each breathing cycle by plotting the instantaneous flow and the tidal volume. The instantaneous inspiratory and expiratory flows were measured at a 50% of the respective (inspiratory or expiratory) portion of the tidal volume, and a breath-by-breath analysis of the mid tidal volume flow ratio (I/E ratio) was obtained. There was a positive significant relationship between I/E ratio and V.sub.
