Publication number: 20170105935Abstract: Provided is a pharmaceutical composition excellent in capability of an accelerated penetration into an affected area. The pharmaceutical composition capable of accelerated penetration into the affected area is formed by dispersing nano-bubbles, which are negatively charged and are given high internal pressures due to their surface tension, in the pharmaceutical composition in a form of a liquid or a gel including a predetermined drug.Type: ApplicationFiled: December 2, 2016Publication date: April 20, 2017Applicants: NAKASHIMA KOGYO CORPORATION, NATIONAL CENTER FOR GERIATRICS AND GERONTOLOGYInventors: Yoji NAKASHIMA, Misako NAKASHIMA, Koichiro IOHARA, Kazumasa YAMADA

Patent number: 8632058Abstract: A micro-bubble generating device is provided which is capable of mixing or dispersing micro-bubbles into a liquid with high stability and has a simple structure that permits reduction of a cost of manufacture. A first member and a first packing are superposed on each other on one side of a gas-permeable film, while a second member and a second packing are superposed on each other on the other side of the gas-permeable film. A pressurized gas delivered via a gas inlet of the first member flows through a fluid passage of the first packing, permeates through the gas-permeable film, and is ejected as micro-bubbles into a liquid flowing through a fluid passage in the form of a narrow shallow strip-like groove provided in the second packing.Type: GrantFiled: September 11, 2012Date of Patent: January 21, 2014Assignee: Nakashima Kogyo CorporationInventors: Yoji Nakashima, Koji Yamada
