  • Patent number: 8936550
    Abstract: An eyelids opening device with a drape comprising a flexible upper ring (1) applied in contact with the face while surrounding eyelids, a lower ring (2) inserted into a conjunctiva sac and applied in contact with the eyelids conjunctiva side, and an elastic sheet (3) of soft tubular thin film located to extend from the face side to the eyelids conjunctiva side and used to fix one end to the upper ring and to fix the other end to the lower ring by expanding, wherein the outside diameter at the smallest portion of the elastic sheet is substantially equal to or longer than the interpalpebral length (between upper and lower eyelids). Difference in size of conjunctiva sac or interpalpebral length of individuals is absorbed even by an appliance of one size, the eyelids can be opened by fitting the eyelids opening device to the eyelids or the face while burden on the eyeball is reduced and high safety is ensured.

  • Publication number: 20120117807
    Abstract: A puncture needle capable of clear imaging even if an angle to the irradiation direction of a detection wave is small. According to one embodiment, a ultrasonic puncture needle that conducts puncturing while observing a puncturing condition by means of a ultrasonic image is formed with an edge at the tip end of a puncture needle body, and formed at a specified position of the puncture needle body with at least one corner cube mirror formed by a triangular pyramid recess. Since a ultrasonic wave oscillated from the ultrasonic probe is reflected off the corner cube mirror to be returned to the ultrasonic probe, the reflected wave progresses in the same direction as the incident direction of the ultrasonic wave to be positively returned to the probe even when an angle formed by the irradiation route of a ultrasonic wave and the axis of the puncture needle is small.

  • Patent number: 8008040
    Abstract: An object of the present invention is to provide a process according to which 5-ene-3-one or 3,6-dione derivatives of sterols can be synthesized with a better yield, as well as a process for production of lipid metabolism improvers, foods, drinks, and animal feeds containing the 5-ene-3-one or 3,6-dione derivatives of sterols. The process for production of 5-ene-3-one or 3,6-dione derivatives of sterols of the present invention involves preparing a culturing solution containing an Arthrobacter bacterium, which is a microorganism exhibiting a cholesterol oxidase activity, and then, adding to the culturing solution an equivalent amount of hexane so as to prepare a bilayer solution consisting of an aqueous layer and a hydrocarbon-based solvent layer. Thereafter, sterol, or a derivative thereof, is made as a substrate contained therein, a reaction performed with cholesterol oxidase at 30° C. for 2 days, and, ethanol then added to separate a hydrocarbon-based solvent layer.
