  • Patent number: 5443461
    Abstract: Diffusional delivery devices are constructed in two or more compartments, each containing a separate drug or other beneficial agent, and each arranged to permit diffusion of the agent out of the device through an individually-characterized agent-permeable wall segment. The diffusion rates of the various agents relative to one another are set and controlled by the parameters of the individual wall segments, such as the surface area of the wall segment, the average thickness of the wall segment, and the permeability of the wall segment for the particular agent. The permeability may be varied by variations in the chemical composition of the wall segment. Using these parameters rather than blending the agents at calculated ratios in a single formulation for diffusion through a single wall permits a wider range of, and greater flexibility in, variation between the diffusion rates of the different agents. This is of value when the simultaneous administration of agents at a specified ratio is desired.

  • Patent number: 5437651
    Abstract: The present invention is directed to a new and useful apparatus and method for absorbing and collecting blood and other fluids which accumulate in a patient during surgical procedures. An absorbent portion is connected to a suction source. When the absorbent portion is placed in contact with the fluid to be collected, the fluid is absorbed by the absorbent portion. Operation of the suction source provides a vacuum which draws the fluid away from the absorbent portion and out of the body. The fluid can be drawn into a receptacle for later cleansing and reuse. A flexible backing plate is attached to the absorbent portion. Channels formed a long the backing plate direct the vacuum evenly across the absorbent portion of the device such that fluid is drawn evenly from the absorbent portion. Suction tubing connects the absorbent portion to the suction source. The absorbent portion and attached backing plate can be folded to fit into small areas.

  • Patent number: 5437653
    Abstract: An absorbent article having two coapertured layers and a method of making the absorbent article are disclosed. The absorbent article includes first and second layers formed from nonwoven materials. The first layer has an open pore structure and has an average fiber denier greater than about 2.5. The second layer has a finer pore structure than the first layer. The first layer overlays the second layer and both layers have a plurality of coaxially aligned apertures formed completely therethrough. The apertures allow body fluid, especially viscous fluid like menses, which is deposited on the first layer to rapidly pass down through both layers.

  • Patent number: 5435806
    Abstract: This diaper comprises at the level of each of its transverse edges, a strip of open cell foam material extending transversely with respect to the diaper and fixed between the support and upper sheets of the latter. These elastic strips are designed to come into elastic contact with the body of a user at the level of the latter's waist. The longitudinal inner and outer edges of each strip communicate respectively with the inner space of the napkin and with the outside of the latter to permit this inner space to communicate thus with the outer space through the thickness of the strips so as to permit the internal ventilation of the napkin.

  • Patent number: 5431638
    Abstract: An accessory device for dissipating electrical energy from a surgical device is provided. The electrical energy is induced on the surgical device when a charge-inducing instrument, e.g. an unipolar electrocautery device, is energized in proximity thereto. The induced energy is dissipated by conveying the energy along an electrically conductive coating adhered to a housing of the device to an energy dissipation region.

  • Patent number: 5431643
    Abstract: An absorbent article including a fluid pervious topsheet, a fluid impervious backsheet joined to the topsheet, and an absorbent core positioned between the topsheet and the backsheet. The topsheet includes a fluid pervious nonwoven material having a patterned network of fluid impervious areas deposited thereon. Bodily fluid deposited on the topsheet is transported through the fluid pervious nonwoven material portion of the topsheet, thereby wetting the nonwoven material while the fluid impervious areas remain dry. The dry fluid impervious areas contrast visually with the wetted nonwoven material portion of the topsheet. This structure provides a topsheet that is perceived as soft and fibrous prior to the discharge of bodily fluids thereon and clean and dry after bodily fluids have been deposited thereon.

  • Patent number: 5429631
    Abstract: A sanitary napkin assembly comprises a plurality of thin, substantially planar, individual sanitary napkin units which are arranged in a stack so that their planar faces are adjacent. Each individual napkin unit is removably attached to the one or two individual units which are adjacent to it. Each individual napkin unit comprises a sheet or layer for receiving, absorbing, and containing body fluids secreted by the user, and a water-proof barrier sheet or layer for precluding leakage of absorbed fluids to adjacent units or to the user's clothing. Thin adhesive-tape strips (or other suitable attachment media) are used to permanently attach the fluid-receiving layer to the barrier layer. Similar tape strips (or other suitable attachment media) are used to removably attach individual napkin units to adjacent units, and to removably attach the assembly to an interior portion of the user's undergarment.

  • Patent number: 5429629
    Abstract: An absorbent article includes a retention portion for storing absorbed liquids, and a distinctive surge management portion. The surge management portion, which has a selected basis weight, is constructed to rapidly uptake and temporarily hold at least three (3) successive surges of liquid directed into the target zone of the article and then release each of the surges to the retention portion. The retention portion desorbs each input of liquid from the surge management portion and stores the liquid. Particular functional and structural parameters can further characterize the surge management portion of the absorbent article.

  • Patent number: 5425355
    Abstract: This invention relates to a surgical instrument. Specifically, a surgical instrument is disclosed which dispenses incising, transecting, or tissue treating energy to a body site or part undergoing an operation or treatment where energy is discharged from a conduit to effect the treatment. The disclosed instrument is inserted to an operative site that effectively rules out proximal manipulation of the instrument. Therefore, proximal insertion with subsequent distal manipulation excluding proximal side-to-side or up and down manipulation is disclosed. The disclosure further includes a deployable shield and is ideal for operative engagement to surgical sites on the body such as the carpal tunnel, tarsal tunnel, the wrist, temporomandibular joint, or scar tissue capsules forming around implants of the breast.

  • Patent number: 5425725
    Abstract: An absorbent article comprises a first, liquid-permeable carrier layer and at least a second carrier layer. A carrier attaching mechanism, such as a water-sensitive adhesive, secures together the carrier layers to provide substantially attached zones and a multiplicity of substantially unattached zones thereof. The substantially unattached zones provide a plurality of pocket regions, and a high-absorbency material is located within the pocket regions to provide an absorbent laminate. Matrix fibers are dispersed within the high-absorbency material in the pocket regions, and the matrix fibers are present in a selected amount which, in particular aspects of the invention, can be within the range of about 0.1-10 weight percent, as determined with respect to the total weight of the absorbent material contained in the pockets.
