  • Publication number: 20050191326
    Abstract: The present invention relates to novel compositions, which provide an indicator for location and/or concentration of the composition during application. In a preferred embodiment, the indicator is a compound that is visible at a first pH and invisible at a second pH. The composition includes the indicator and a volatile base or acid. The volatile base or acid enables the composition to be at a first pH so that the indicator is visible when first applied to a desired surface. However, upon evaporation or degradation of the volatile acid or base, the composition will be at a second pH, causing the indicator to disappear.

  • Patent number: 6909912
    Abstract: The present invention relates to a novel non-invasive perfusion/resistance status monitor system and methods of using the same, and more specifically, a vascular perfusion status monitor system receiving and processing signals from at least two pulse oximeter probes, where each of the at least two pulse oximeter probes are situated at advantageously different locations in a patient. Novel pulse oximeter probes are configured to be placed, respectively, across the lip or cheek, across the septum or nares of the nose, and on the tongue. These probes are fabricated to provide signals to estimate arterial oxygen saturation. Conventional oximeter probes also can be configured to function according to the novel methods of determining differences in peripheral blood flow and/or resistance described herein.

  • Publication number: 20050054942
    Abstract: The present invention includes systems and methods for monitoring therapeutic drug concentration in blood by detecting markers, such as odors, upon exhalation by a patient after the drug is taken, wherein such markers result either directly from the drug itself or from an additive combined with the drug. In the case of olfactory markers, the invention preferably utilizes electronic sensor technology, such as the commercial devices referred to as “artificial” or “electronic” noses or tongues, to non-invasively monitor drug levels in blood. The invention further includes a reporting system capable of tracking drug concentrations in blood (remote or proximate locations) and providing the necessary alerts with regarding to ineffective or toxic drug dosages in a patient.

  • Publication number: 20040099263
    Abstract: A novel connection device, and method for its use, for connecting a volume displacement detection device and a gas composition detection device in line with an intubation tube is disclosed. The connection device allows a user to combine two systems commonly employed by medical personnel to assess the location of an intubation tube placed into a patient. The two systems have alternate means of assessing the location of an intubation tube in a patient and therefore, when combined into a single unit via the connection device, improve the accuracy of placing a tube in a desired location while reducing or eliminating complications associated with misplacement. A kit comprising components that may be assembled to provide a device for assessing the proper placement of an intubation tube in a patient is also disclosed. The kit may be used in any environment, but is particularly well suited for emergency, pre-hospital settings requiring intubation where quick assembly of the components is essential.

  • Publication number: 20040079376
    Abstract: Disclosed herein is a novel tube-in-tube endotracheal tube apparatus that allows for replacement or cleaning of an inner (first) tube without having to re-intubate the patient. The novel endotracheal tube apparatus enables the application of continuous suction or intermittent suction. The endotracheal device also serves to decrease the incidence of ventilator-associated pneumonia (VAP).

  • Publication number: 20030159693
    Abstract: A small breath-activated, microprocessor controlled device that can be used with any drug formulation appropriate for pulmonary delivery is disclosed. A fixed-resistor housing incorporates a microprocessor and pressure transducer to detect pressure changes associated with patient derived airflow across the device. The microprocessor determines the flow rate and tidal volume over several breaths and averages them. Depending on where in the brocho-pulmonary tree the drug is to be administered, the microprocessor will precisely meter the drug in the appropriate phase of the respiratory cycle and deliver small aliquots of the formulation over several breaths until the total dose is administered.

  • Publication number: 20020068851
    Abstract: The subject invention pertains to a system for imaging the human airway having highly advantageous optical, mechanical, ergonomical and physical characteristics. In a specific embodiment, the human airway can be imaged during the intubation procedure. The subject imaging scopes can incorporate a malleable stylet which its shape when bent, in order to facilitate intubation of a patient. In a preferred embodiment, a solid metal stylet, for example, a conventional endotracheal tube stylet, can be utilized. In a specific embodiment the subject intubation scope allows for a user to utilize conventional techniques for the insertion of an endotracheal tube, reducing the training needed for use of the subject intubation scope. Preferably, the subject imaging scopes also incorporate at least one illumination fiber to convey light to the distal tip of the subject imaging scopes, for illumination of the objects to be imaged.

  • Patent number: 6115523
    Abstract: The subject invention pertains to a system for imaging the human airway having highly advantageous optical and physical characteristics. In a specific embodiment, the human airway can be imaged during the intubation procedure. The excellent characteristics of the imaging system of the subject invention result, in part, from the use of plastic optic fibers. Plastic fibers are more robust than the glass optical fibers used in currently available imaging systems, and are therefore capable of being bent and/or twisted with less concern of breakage. In addition, the lower costs of plastic fibers enables scopes of the subject invention, in a specific embodiment, to be manufactured for single patient use thereby eliminating the requirement for cleaning, special care, the maintenance of expensive inventory, and most importantly eliminating the opportunity for cross contamination between patients.

  • Patent number: 5997891
    Abstract: This invention relates to novel compositions containing temporary visual indicators and methods for using these compositions. Specifically, this invention relates to a sunscreen composition containing an indicator that is visible when the substance is applied to the skin, but becomes invisible shortly after application. The continued presence of the indicator allows the indicator to be reactivated temporarily to the visible form so that a user can verify the presence of the sunscreen. The visible indicator ensures that the sunscreen is applied evenly and completely to the area to be protected, but becomes invisible so as not to interfere with the action of the sunscreen or discolor the skin.

  • Patent number: 5599303
    Abstract: The subject invention is a novel apparatus for the administration of intravenous fluids. The invention is particularly well suited for accurately and efficiently administering intravenous fluids over a wide range of flow rates. Disclosed is an intravenous fluid administration apparatus having at lease one flow line capable of administering fluid at high flow rates and comprising an airless, dripless, fluid monitoring chamber. A preferred embodiment comprises a main flow line which diverges into at least two flow limbs, where one flow limb is a low-flow limb and another flow limb is a high-flow limb, each having separate flow indicators, and with the flow limbs typically converging into a common tube for fluid delivery to the patient. The subject invention also discloses a novel flow meter, which is particularly well suited for measuring and indicating flow rates over a wide range, without the introduction of air bubbles into the fluid flow being measured.
