摘要:
An improved acoustically and thermally insulating fire-retardant composite material suitable for use in structures such as buildings, appliances, and the interior passenger compartments and exterior components of automotive vehicles is provided. The material is comprised of at least one airlaid fibrous layer of controlled density and composition and incorporating suitable binding agents and additives as needed to meet expectations for noise abatement, fire-retardancy, and mildew resistance. Separately, an airlaid structure which provides a reduced, controlled airflow therethrough useful for acoustic insulation is provided, and which includes a woven or nonwoven scrim. A process for the production of the fire retardant nonwoven material is also provided.

The present invention relates to an absorbent core for use in an absorbent article and methods to make the absorbent core and absorbent articles. The absorbent core has a discrete wicking layer made with compressible fibers such as a eucalyptus or chemically treated fibers. The absorbent core and articles made with it have improved vertical wicking capacity and superior rewet characteristics.

A discrete superabsorbent layer is adhered to the lower surface of a fibrous absorbent structure using a water-based polymeric binder is disclosed. The advantages are that a superabsorbent roll good can be prepared for later conversion into disposable absorbent products. The use of the water-based polymeric binder prevents particles of superabsorbent from becoming dislodged from the structure during handling and processing.

The invention features a needle defining a flowpath, a housing comprising a proximal end and a distal inner seat leading to and defining a lumen, and a viscous material contained within the housing. The needle is slidable through the housing and the viscous material contained therein. The viscous material is fluid enough for the needle to slide therethrough, yet semi-solid enough to conform to the housing distal inner seat so as to form a seal thereat and prevent flow of fluid or air through the lumen.

The invention features a needle and a housing having a proximal inner surface and a distal inner seat leading to and defining a lumen, wherein the needle is slidable through the housing to occupy the lumen. The housing contains and is cooperable with a valve shaped so as to sealably fit against the housing distal inner seat, the valve including a hole alignable with the lumen. When the needle slidably occupies the housing, the valve hole, and the lumen, the valve is prevented from sealably fitting against the housing distal inner seat. The housing also contains an outward biasing means biased against the valve. Upon removal of the needle from the housing, the outward biasing means urges the valve sealably against the housing distal inner seat so as to prevent flow of fluid or air through the lumen.

Disclosed is a urodynamic catheter having a fill lumen for filling the bladder with liquid; at least a first pressure-sensing lumen having an opening adapted for being positioned within the bladder for obtaining pressure readings of the bladder; and preferably also a second pressure-sensing lumen having an opening adapted for being positioned within the urethra while the opening of the first pressure-sensing lumen is within the bladder, the opening in the urethra being for obtaining pressure readings of the urethra.Each pressure-sensing lumen has a radio-opaque element fixedly seated therewithin in close proximity to and distal to the opening in the lumen for determining proper placement of the catheter within the patient.
