  • Patent number: 9662012
    Abstract: The invention is directed to quantification of the effects of drugs on a patient using pupillometric measures. Apparatus and processes for obtaining control and patient measures and deriving relationships from same are provided. The methods of the invention provide doctor quantitative feedback on patient symptoms and on the effects of a drug or dosage of same on a patient, as well as provide assessment capability to patients and law enforcement.

  • Patent number: 7931594
    Abstract: A system and method for regional anesthesia using ultrasound to assist in locating the anesthetic needle are disclosed. One or more piezo-electric crystal transducers is placed either at the tip of the needle or near the tip of the needle on a stylet which is inserted into the lumen of the needle. The transducer(s) are pulsed with ultrasonic frequency, the reflected ultrasonic signals from structures are detected and converted into a digital signal and may be displayed in an oscilloscopic format to indicate anatomical structures forward to the needle and allow the medical professional to avoid errors and/or increase efficiency and accuracy. An array of transducers can be pulsed in a phased array fashion to generate a 2D image, or a single transducer can be pulsed to generate a 1D image. A 2D image can also be obtained by mechanically sweeping a single transducer, for example by means of a miniature motor in or at the base of a needle or stylet.

  • Publication number: 20090124867
    Abstract: A method of and a device for non-invasively measuring the neurological depressed state and the hemodynamic state of a human patient and involving steps and units of non-invasively measuring EEG, cardiac cycle period, electrical-mechanical interval, mean arterial pressure, and ejection interval and converting the EEG into a neurological index as well as converting the measured electrical-mechanical interval, mean arterial pressure and ejection interval into the cardiac parameters such as Preload, Afterload and Contractility, which are the common cardiac parameters used by an anesthesiologist. A general anesthetic is administered based upon the converted neurological index. A vasoactive agent is independently administered based upon the converted cardiac parameters as necessary in order to restore cardiovascular homeostasis in the patient.

  • Patent number: 4989835
    Abstract: A vehicle security barrier which can be conveniently placed across a gate opening as well as readily removed from the gate opening to allow for easy passage. The security barrier includes a barrier gate in the form of a cable/gate member in combination with laterally attached pipe sections fixed by way of the cable to the gate member and lateral, security fixed vertical pipe posts. The security barrier of the present invention provides for the use of cable restraints across gate openings to provide necessary security while at the same time allowing for quick opening and closing of the gate areas without compromising security.
