The system has an anti-reflux valve comprising a sheet of flexible material having an upper portion and a lower portion and extending across said drip chamber such that the sheet is sufficiently large to engage against said seat peripherally around the drip chamber.

Abstract: Novel system for providing anti-corrosion protective coatings, e.g. for metal pipes and the like, comprising: (1) a rubber-based primer coating mixture; and (2) an adhesive tape comprising a backing carrying a rubber-based adhesive coating comprising a mixture of pre-crosslinked butyl rubber and virgin butyl rubber alone or in combination with reclaimed butyl rubber, the system further including a crosslinking agent and a crosslinking activator adapted to provide an incipient or in situ crosslinking of the system after the primer coating and tape are applied.Preferably, the crosslinking agent is contained initially in the adhesive coating; and the activator is contained initially in the primer.

Abstract: Novel systems for bonding a polyarylate substrate to another polyarylate substrate or to a polycarbonate substrate, at least one of the substrates being transparent, employing a visible light curable adhesive composition consisting essentially of:(1) at least one member of the group consisting of monofunctional acrylic monomers, polyfunctional acrylic monomers, and polyfunctional polyester acrylate oligomers;(2) N-vinyl pyrrolidone;(3) at least one low molecular weight aliphatic urethane acrylate polymer; and(4) a catalyst or photoinitiator activatable by visible light.The invention is particularly directed to the bonding of component parts of automotive headlamp assemblies, at least one component of which comprises a polyarylate.

Abstract: Nasogastric intubation device having a removable stylet or stiffening wire to facilitate proper intubation, wherein the stylet is provided with a surface coating consisting essentially of alkaline earth metal salts of an unsaturated and a saturated higher fatty acid containing at least 16 carbon atoms.

Abstract: A sleeve for applying compressive pressures against a patient's limb from a source of pressurized fluid, wherein the sleeve comprises a multi-layered sheath, having a proximal and a distal end. Generally parallel side edges extend between the proximal and distal ends, which side edges, on the proximal half of the sheath, are adjustably wrappable about the patient's limb, once it is inserted in the sleeve.

Abstract: An absorbent dressing comprising, a transparent backing sheet having a relatively high water vapor permeability, a front sheet having a pressure sensitive adhesive on a front surface thereof for facing a wound with the front sheet and adhesive having a plurality of apertures extending therethrough, and an absorbent layer intermediate the front sheet and backing sheet having a plurality of openings in register with the apertures of the front sheet, with the openings of the layer being at least as large as the apertures of the front sheet.

Abstract: Novel rubber-based adhesive coatings adapted for use as a primer coating for pipelines, which coatings include a reagent which inhibits formation of hydroxide ions resulting from electrons generated by cathodic protection, and novel protective pipewrap systems including same.

Abstract: A device for performing a procedure comprising, a first tray, a second tray positioned adjacent a side the first tray, and a flexible splash shield extending from a location adjacent the juncture of the first and second trays and being movable between a first position substantially covering the first tray and a second position substantially covering the second tray.

Abstract: Adhesive compositions comprising at least one free radical acrylic monomer and a free radical initiator, which compositions further include a stabilizer mixture for improving shelf life comprising a polymerization inhibitor, a metal chelating agent, and a free radical scavenger, the stabilizer mixture being present in an amount sufficient to inhibit gelation during shelf life of the composition.

Abstract: A device for testing a package having, a device for passing a fluid inside the package, and a device for selectively controlling the rate of pressure increase inside the package by the passing device.

Abstract: A surgical sponge comprising, a sheet of absorbent material. The sponge has an elongated visually detectable element at a visible location on the sheet comprising a pair of elongated twisted strands. One of the strands has a color which contrasts with the color of the sheet, and the other of said strands has a color which contrasts with the color of blood.

Abstract: The present invention comprises a urine collection bag with a tilt bag indicator on the front wall thereof. The indicator comprises a clear patch or housing disposed to the side of the input conduit of the containment bag. An orifice is disposed through the front wall to provide communication between the chamber of the collection bag and the chamber defined by the transparent patch and the front wall of the bag. If the bag is tilted, urine will escape the collection bag chamber and go into the indicator chamber, and be trapped there. This will alert appropriate medical personnel that a reflux of urine up the input conduit, thus allowing whatever corrective action be taken, as necessary.

Abstract: A stepped needle comprising, a proximal hollow hub, a first elongated tubular portion extending from the hub of a first larger diameter, and a second elongated tubular end portion located distal the first tubular portion of a second smaller diameter.

Abstract: Novel roof membranes for providing improved lap joints with adjacent roof membranes, wherein opposed edges of the adjacent membranes for the lap joint are tapered.

Abstract: A wound dressing adapted for preventing pooling of wound exudate and for promoting healing comprises, in order:(a) a layer consisting essentially of hydrogel for placement on a wound, the hydrogel being characterized as being wound friendly and for absorbing and acting as a reservoir for wound exudate;(b) an intermediate layer disposed over said hydrogel layer. The intermediate layer comprises a tacky hydrogel or hydrocolloid adhesive, the tacky hydrogel or hydrocolloid adhesive characterized as having a greater absorbent capacity that does the hydrogel in the hydrogel layer; the underlying hydrogel layer is characterized as being more friendly and consequently more suitable for direct wound contact than the overlying adhesive hydrogel of greater absorbent capacity; the intermediate layer having sufficient moisture permeability therethrough to the surface of the dressing;(c) an outer oxygen- and vapor-permeable layer adapted for transpiration of at least a portion of fluid diffusing through the dressing.

Abstract: A humidification apparatus for utilization in human respiration systems comprising a hollow housing in which an envelope of vapor permeable water impermeable material is arranged to divide the housing generally in half. A heater and a water supply conduit are arranged in the envelope. A gas inlet and a gas outlet port are disposed through the housing and are in communication with each other. The heater changes the water into vapor and permits it to pass through the envelope and be carried with the gas, out of the housing to a patient.
