  • Patent number: 8375688
    Abstract: A package for a cryopreservation container including at least an adhesive fluoropolymer film. The package for a cryopreservation container makes it possible to store blood, rare cells and vital tissues in a very low temperature environment without any damage to the container. Further, the sealing strength resulting from heat sealing after placing a cryopreservation container in the packages is very good. Therefore, liquid nitrogen can be inhibited from entering the inside and thus contamination with bacteria, viruses or the like contained in liquid nitrogen can be avoided and the package can be prevented from being broken by expansion of intruder liquid nitrogen on the occasion of thawing. Also disclosed is a method for packaging a cryopreservation container and a method of producing a package for a cryopreservation container.

  • Patent number: 8371859
    Abstract: The kit for suppressing drug craving K is used by connecting an instrument for suppressing drug craving 1 to a syringe 2 and the instrument for suppressing drug craving 1 has a cylindrical housing 11, a pouch 12 provided in the housing and containing pseudo-blood B and a connecting member 13 with which the distal end of a syringe is coupled and which cause the syringe to communicate with the interior of the pouch. When the syringe accommodating pseudo-drug M is connected to the instrument and the plunger is moved forward (pseudo-priming), the pseudo-drug M flows into a pouch and the pouch inflates (FIG. 2(b)), and if the plunger 4 is pulled back from this condition, the pouch 12 deflates and the pseudo-blood B flows back from the pouch 12 to the syringe 2 (flashback) (FIG. 2(C)).

  • Patent number: 8287464
    Abstract: A metal needle is obtained by being dipped in a liquid selected from the group consisting of a strong acid solution of a metal, acetic acid, and butyl acetate, and then dried. Preferably, the strong acid solution of a metal to be used in the dipping treatment may be a nitric acid solution of a metal selected from the group consisting of a transition element, a lanthanoid, and an actinoid, for example, a nitric acid solution of a metal selected from the group consisting of palladium, gadolinium, germanium, beryllium, strontium, scandium, and samarium. The metal needle is a metal needle for insertion into the body that can be reliably imaged even when a general-purpose ultrasound imaging system is used, and thus is useful in confirming insertion of the needle into a blood vessel and arrival of the needle at an organ, and confirming the position of the needle when it is broken.
