  • Patent number: 8795607
    Abstract: The invention relates to a container (1) for a fluid for metering a reagent into a microfluidic system. The container comprises a chamber (4) and a first film (3) which seals off the chamber (4) so that the fluid is encapsulated in the chamber. Advantageously, the first film (3) is an aluminum sealing film. A second film (7) is sealingly arranged on the first film, for example by adhesive bonding of the film layers. The films differ in their tear strength such that when pressure is applied simultaneously to both films the first film tears while the second film deforms elastically and/or plastically. By tearing the first film a connection is produced between the container chamber and an inlet channel so that a fluid contained in the chamber flows into the microfluidic system.

  • Publication number: 20110223060
    Abstract: The present invention provides an apparatus and method for disinfecting a target area of a patient's body, such as an arm, leg or a chest, in a pre-surgical environment. The apparatus and method disclosed herein further provides for maintaining the target area of the patient's body in an aseptic condition while transporting the patient to and into the surgery room. The most preferred embodiments of the present invention contemplate the use of one or more sterile layers (e.g., sterilized bags or the like) that are used to enclose the target area of the patient's body coupled with a sterile substance delivery mechanism that disinfects the target area and also maintains the target area in an aseptic condition. The most preferred embodiments of the present invention comprise a single-layer disposable garment or an inner bag nested inside an outer bag with a sterilization material being introduced into the inner bag, thereby disinfecting the target area.

  • Patent number: 7906070
    Abstract: There is provided an improved sterilization wrap and a method for using the improved sterilization wrap to sterilize an article. The wrap is made of at least a first panel of sterilization material and includes an additional panel of material. The first panel is multi-layered and includes at least one pathogen filtration layer. The first panel is rectangular and has an outer periphery and a central portion. The outer periphery includes first, second, third and fourth edges. The additional panel of material is bonded to the first panel, approximately at a forty-five degree angle to the first panel, with a substantial portion of the additional panel being adjacent to the central portion of the first panel. The perimeter of the additional panel is smaller than the perimeter of the first panel. Portions of the additional panel are bonded to the first panel along the first, second, third and fourth edges of the first panel.

  • Patent number: 7862877
    Abstract: A sanitary article is provided for reducing the spread of contamination between a user and an object. The article comprises a permeable layer, an impermeable layer, and an anti-bacterial gel interposed between the permeable layer and the impermeable layer. The permeable and impermeable layers may be sealed to each other to restrict the movement of the gel and to make the article unitary. The gel may at least partially diffuse through the permeable layer upon the user contacting the permeable layer while the impermeable layer impeded diffusion of the gel toward the object upon the object contacting the impermeable layer.

  • Patent number: 7794675
    Abstract: A medical swab pouch is disclosed. The inexpensive elastic pouch contains disinfectant and is configured for protecting and swabbing a wide variety of luer systems to prevent and eliminate bacterial contamination. The pouch has a flattened configuration and can be elastically dilated, as by squeezing the pouch between the thumb and index finger and is readily carried in large numbers in nurse's pockets (in a manner similar to that for conventional alcohol swabs). The pouch covers and protects the luer valve at the discretion of the user and without transmission of torsion or longitudinal force which might loosen the luer valve or otherwise be transmitted to the vein.
