Abstract: There is provided a a respiratory gas delivery and sampling system, a gas sampling system, a gas sampling interface and a gas sampling tip that may be used to sample exhaled and/or expired gases from a patient, particularly from a patient who is apnoeic and/or who is receiving high flow respiratory therapy. The gas sampling system comprises a respiratory gas monitor in fluid communication with the gas sampling interface, which comprises the gas sampling tip of the invention. The gas sampling interface comprises a gas sampling conduit and the gas sampling tip is located at a free end of the conduit. The gas sampling interface may be configured to allow the gas sampling tip to be selectively positioned at or in the mouth or a nare of the patient's nose.

Abstract: There is disclosed system for oxygenating a patient in relation to anaesthesia using high flow gas delivery. The system has a flow source, and a controller for determining oxygenation requirements of the patient before or during anaesthesia. A method of oxygenating a patient in relation to anaesthesia using high flow gas delivery is also disclosed. The method determines oxygenation requirements of the patient before or during anaesthesia.

Abstract: A respiratory assistance system can provide high flow therapy to patients. The respiratory assistance system can include a patient interface that can deliver a gas flow to a patient and a gas source that can drive the gas flow towards the patient interface at an operating flow rate. The system can include a controller for controlling the operating flow rate of the gas. The controller can apply multiple test flow rate values in a range as the operating flow rate. For each of the test flow rate values, the controller can measure a patient parameter. The controller can determine a new flow rate value based on the measured patient parameters. Patient parameters can include respiration rate, work of breathing, or any other parameters related to the respiratory circuit.

Abstract: Polymer polyols are made in a seeded process, in which styrene and acrylonitrile are polymerized in the presence of a base polyol, a seed dispersion and a solvent. The seed dispersion contains an unsaturated macromer. The process produces a polymer polyol in which the dispersed phase particles have a particle size of 1 to 3 ?m and a particle size span of less than 1.25. The polymer polyols are very useful for making flexible polyurethane foam for cushioning applications, in which high airflows and good load bearing are needed.

Abstract: Viscoelastic foam is made by reacting an isocyanate compound with water and a polyol mixture. The polyol mixture contains a dispersion of polyurethane or polyurethane-urea particles in a carrier polyol (a PIPA polyol) and at least one other polyol that is a homopolymer of propylene oxide or a copolymer of 20 to 99.9 weight-% propylene oxide and 0.1 to 80 weight-% ethylene oxide, has 2 to 4 hydroxyl groups per molecule and has a hydroxyl equivalent weight of 200 to 400. The VE foams are characterized by high airflows and long recovery times.

Abstract: Multiple conductor electrical power cords, signal transmitting wiring and cable is insulated with one or more layers or sheathing of a thermoplastic polymer composition with at least the outer layer of the composition containing contaminant resistant or combating agents that inhibit growth of biological contamination. The microbial resistant cord or wiring has particularly advantageous utility of power cords for use with appliances or electrical products in facilities that affect health, such as medical and food related facilities that require safeguarding against contaminating microorganism attack formation, or growth.

Abstract: The invention is a combination of a Methyl Methacrylate liquid monomer and an acrylic powdered polymer that when mixed together will form an extremely strong chemical bond between two plastic substrates by melting into the plastic and filling the space between the substrates. A bond stronger than previously achievable is accomplished by two factors: (1) Substantial use of the liquid as a primer before the application of the mixture in order to prepare the surface for welding. (2) Controlling the temperature of the liquid and the powder, via refrigeration, before mixing. This allows workability of the product without the need for additives that dilute the strength of the mixture. The elimination of the additives also allows for a more pure weld that can be polished to a crystal clear surface for an esthetically pleasing joint.

Abstract: A holding device for supporting electric or battery-operated window candles in an upright vertical position for viewing through a window. The holding device is comprised of a horizontally extending U-shaped support base, and a vertically extending clip for attaching to a window sash which connects the support base and candle to the window. The support base accommodates a design that holds the candle base in a stationary position while the opposite end abuts the clip and window sash. The clip is attached to the window sash where said sash meets the window sill and extends upwardly. The support base and candle are connected to the window by attaching the back wall of the base to the clip that abuts the window sash. The profile and design does not impede access to normal window functions leaving space between the candle and window handle for grasping.
