Abstract: This invention provides a disposable urinary pad comprising a liquid-impermeable backing, an absorbent core and a liquid permeable facing adhered to the shell so as to entrap the absorbent core therebetween. The absorbent core comprises a web of absorbent fibers and superabsorbent material and has a liquid-permeable transfer layer adjacent to one surface. The absorbent core is pleated, as in an M-configuration, to form therein a center lengthwise channel. The transfer layer, after pleating of the absorbent core, extends down the sides of the core so as to provide a liquid path to the bottom of the core.
Abstract: Hybrid cell line for production of monoclonal antibody to an antigen found on normal human suppressor T cells. The hybrid is formed by fusing splenocytes from immunized CAF.sub.1 mice with P3X63Ag8Ul myeloma cells. Diagnostic and therapeutic uses of the monoclonal antibody are also disclosed.
Abstract: An arcuate shaped body fluid absorbent product is made by a process which employs the steps of delivering onto an arcuate shaped surface a composite comprising a layer of body facing cover material, a layer of absorbent core and a layer of garment facing cover material. The core, sandwiched between the two cover materials, is planar in the relaxed state. The cover materials are sealed together about the periphery of the core while the composite is deformed on the arcuate shaped surface to produce an arcuate shaped product.
Abstract: Dry laid board comprising peat moss is provided and made by harvesting peat moss having a degree of decomposition of H-1 value as measured by the Modified Von Post Scale, individualizing the harvested peat moss, drying the individualized peat moss and entraining the peat moss in a gas stream. The entrained peat moss is then condensed to form a low density peat moss containing board which is subsequently calendered for use in such products as dressings, diapers and sanitary napkins.
Abstract: A sanitary napkin is provided which obviates the problem of stain propagating across the body facing side of the napkin while still facilitates manufacturing processes. Specifically, the napkin comprises a pad having a wrapper which overlies the garment facing side of the pad, the longitudinal sides of the pad, and peripheral portions of the body facing surface of the pad. The wrapper comprises a body fluid impervious sheet laminated to a fibrous sheet with the fibrous sheet being wider than the impervious sheet. The fibrous sheet has a width sufficient to overlie the garment facing surface, the longitudinal sides and the longitudinal peripheral portions of the body facing side of said pad, but is insufficient in width to overlie the central major portion of the body facing surface of the pad.
Abstract: A product for absorbing body fluids intended to be worn in the crotch portion of the undergarment is provided. The product includes a first absorbent layer at the side nearest the body and a second absorbent at the side facing the garment. The layers have therebetween liquid flow retarding means to retard liquid from passing from one absorbent layer to the other. The liquid retarding means comprise one or more plies of a web of hydrophobic fiber which web has a rising column strike through value of at least 10 inches of water and an air permeability of at least 20 cubic feet per foot squared per minute.
Abstract: A panty liner is provided which will prevent the strike through of absorbed liquid body fluids while allowing evaporated body fluids to pass therethrough. The liner includes one or more plies of a fibrous layer which is liquid repellent and air permeable.
Abstract: Crosslinked water absorbent carboxylic polyelectrolytes and articles made therefrom are provided. The polyelectrolytes are crosslinked using a di- or tri-functional aziridine crosslinking agent.
Abstract: The disposable adaptor to permit aspiration and/or irrigation fluid to pass through an ultrasonic surgical instrument without permitting leakage of the fluid from or into the interior of the instrument. The adaptor includes a generally annular housing defining a lumen for receiving the horn of the ultrasonic instrument and having inner seals forming a seal between the confronting surface of the adaptor and horn for prohibiting leakage along the exterior wall of the horn and an outer seal for forming a tight seal between the confronting surface of the adaptor and the instrument shroud for prohibiting leakage along the exterior surface of the adaptor. The adaptor includes a flange at its distal end with a circumferential groove extending partially about the adaptor and cooperating with a mating projection on the distal end of the instrument shroud to provide rotational orientation for the adaptor with respect to the shroud.
Abstract: A system for supervising one or more individual member accounts comprising a first data file for storing information characterizing each employer, a second data file for storing information characterizing each union member, and password protected provisions for manually updating each of these first and second data files. Each of the accounts are represented by an account module provided with an account processor, an account storage, and an account entry unit and each account module is in communication with the first and second data files. The system allows limited access to each account while utilizing central files characterizing each employer and union member.
Abstract: A cassette assembly for a microsurgical system. The cassette comprises a body portion, a collection vessel and a suction conduit which may be occluded to interrupt suction. The cassette may also include an occludable infusion conduit for providing infusion through the cassette to a surgical site.
Abstract: A sanitary napkin is provided which comprises a cover with clean and dry properties in combination with the fluid transport properties of an impressed channel. The napkin comprises an absorbent core having impressed into its body facing side at least one elongated channel. A hydrophobic, body fluid pervious, cover overlies said body facing side and said channel and said cover extends into the channel and is adhered to the channel bottom.
