  • Publication number: 20070224639
    Abstract: A substrate for immobilizing biomolecules comprises a chip substrate, a hydrophilic monolayer, and a lipid bilayer, and a biochip comprising the substrate for immobilizing biomolecules on which biomolecules are immobilized. The substrate for immobilizing biomolecules includes a transparent chip substrate, a metal layer provided on the chip substrate, a monolayer provided on the metal layer, and a lipid bilayer provided on the monolayer. The metal layer is composed of fine particles of Au, the monolayer is composed of self-assembled molecules represented by X—(CH2)n—OH (where X is a thiol group), and the lipid bilayer is composed of self-assembled phospholipids. The monolayer and the lipid bilayer are relatively flexibly bound together via hydrogen bonds. In the biochip, a receptor is immobilized on the lipid bilayer via a biorecognition molecule.

  • Patent number: 5240111
    Abstract: A package in which an article is sealingly enclosed with a thermally shrinkable film having a row perforations used as air discharge port during shrink packaging. A strip of a film is disposed inside of the package to close the perforations and to prevent moisture and germs from entering into the package during storage and transportion of the package.

  • Patent number: 5171046
    Abstract: An improved assembly, composed of a hard member and a soft tube fitted onto the hard member, for medical uses is formed with a plurality of projections on the side wall of a flange of the hard member. The projections project toward the soft tube side to firmly hold the foremost end part of the soft tube between the projections and a fitting portion of the hard member in a clamped state when the soft tube is fitted onto a fitting portion of the hard member. The foremost end surface of the soft tube may slantwise be cut to define a certain angle relative to the center axis of the assembly such that the foremost end part of the soft tube comes in tight contact with the side wall of the flange when the soft tube is fitted onto the fitting portion of the hard member. The soft tube may be formed with a plurality of cutouts which are arranged along the periphery of the foremost end surface of the soft tube in a spaced relationship.

  • Patent number: 5041106
    Abstract: An improved infusion needle device of the type including a liquid delivering passage and an air introducing passage extending in parallel with each other includes a tubular needle, a bottom portion into which the rear part of the tubular needle is immovably fitted, a flange portion made integral with the bottom portion, a cover member airtightly secured to the flange portion and a valve disc received beneath a circular projection on the flange-shaped part of the cover member. As air enters through an air inlet port on the flange portion, the valve disc is raised up so that air is introduced into the interior of the parenteral liquid container via a cutout on the circular projection, a clearance between the bottom portion and the cover member and an annular clearance between the tapered foremost end of the cover member and the tubular needle.
