Patent number: 9522244Abstract: A brain cooling apparatus is provided that can circulate a fluid between a containing unit of a brain cooling device and the brain cooling apparatus while maintaining an appropriate pressure of the fluid in the containing unit, and a brain cooling device suitable thereto also is provided. A control device circulates a physiological saline solution between a storage tank and a cuff by driving a first pump in a direction in which the physiological saline solution flows toward the cuff, and driving a second pump in a direction in which the physiological saline solution flows toward the storage tank. In this state, the control device adjusts the rotation speed of at least the second pump, so that the pressure of the physiological saline solution in the cuff becomes a preset target pressure.Type: GrantFiled: February 21, 2011Date of Patent: December 20, 2016Assignees: KAIKEN IKI KABUSHIKI KAISHA, NATIONAL UNIVERSITY CORPORATION OKAYAMA UNIVERSITYInventors: Yoshimasa Takeda, Kiyoshi Morita, Hiroshi Hashimoto, Hidekazu Tsuji, Masatomo Kokubu

Patent number: 9027482Abstract: There is provided an economical vehicle vibration suppression device capable of efficiently reducing a vortex with a smaller number of devices and controlling the speed of movement in a vehicle longitudinal direction of the vortex. The vehicle vibration suppression device includes a pair of ducts, a pressure control device, and a control unit. The ducts, below a floor surface of a vehicle body, are mounted adjacent to at least a pair of bogies on which the vehicle body is mounted. The ducts are arranged in a direction perpendicular to a traveling direction of the vehicle body and mounted so as to penetrate through both side surfaces of the vehicle body. The pressure control device is mounted within each of the ducts and has openings, one of the openings serving as an intake port and the other opening serving as a discharge port. The pressure control device generates a pressure difference in each of the ducts.Type: GrantFiled: September 14, 2011Date of Patent: May 12, 2015Assignee: Hitachi, Ltd.Inventors: Masataka Hidai, Kenjiro Goda, Kiyoshi Morita

Patent number: 8221481Abstract: A brain cooling device is provided to cool the brain sufficiently to the subcortical tissue in a short time. The device includes a cuff (3) capable of storing therein a cooled fluid and placeable in the esophagus (H1) of the patient (H) when inserted orally or transnasally. A tube (2) extends from the cuff (3) for infusing the fluid into the cuff (3) placed in the esophagus (H1) from outside the body of the patient H and discharging the fluid from the cuff (3). The cuff (3) has flexibility so as to inflate or deflate in response to infusion or discharge of the fluid and is configured in such a manner that when the fluid is infused therein while placed in the esophagus (H1), the cuff (3) that has been inflated comes into close contact with the inner wall (H4) of the esophagus (H1).Type: GrantFiled: September 13, 2006Date of Patent: July 17, 2012Assignees: National University Corporation Okayama University, Daiken Iki Kabushiki KaishaInventors: Yoshimasa Takeda, Kiyoshi Morita, Kouji Yoshida, Takeharu Kobayashi
