Patent number: 8874194Abstract: An apparatus which can detect leak of a liquid injected through an injection needle into a blood vessel of a human body near its surface with high accuracy. The apparatus emits a light ray in a predetermined wavelength band containing a particular wavelength at which the reflectivity for the liquid is lower than the reflectivity for internal tissues of the human body, and detects the light ray in the wavelength band reflected inside the human body. The leak of the liquid can be detected without being affected by variations in the human body or physical condition.Type: GrantFiled: June 27, 2011Date of Patent: October 28, 2014Assignee: Nemoto Kyorindo Co., Ltd.Inventors: Seiichi Ono, Masahiro Sakakibara

Patent number: 8320999Abstract: A leak detector sequentially emits pulse signals toward a human body at a position at which a needle is inserted, detects pulse signals reflected inside of the human body, and measures a time interval between the emission and the detection for each of the pulse signals. The leak detector then calculates the difference between the measured interval and a predetermined time interval, and generates a leak warning for notification when the difference exceeds an acceptable range. Since a swelling on the surface of the human body causes a path of the pulse signal to extend, the leak detector can detect, based on the extended signal path, that the needle has come off a blood vessel.Type: GrantFiled: June 8, 2009Date of Patent: November 27, 2012Assignee: Nemoto Kyorindo Co., Ltd.Inventor: Seiichi Ono

Patent number: 7887513Abstract: A chemical liquid injection system which a piston driving mechanism is driven only when a cylinder holding mechanism appropriately holds liquid syringes of various sizes through a cylinder adapter and such manner. When the liquid syringe 200S of a size other than the maximum size is appropriately held by the cylinder holding mechanism 120, RFID chip 230 is located on the side at the rear of metallic cylinder holding mechanism 120. A pair of resonance antennas are disposed on the left and right of the RFID chip, and an RFID reader 131 is disposed below the resonance antennas.

Patent number: 7686789Abstract: A medical liquid injection system capable of automatically preventing a piston drive mechanism from being driven when a cylinder holding mechanism does not hold a medical liquid syringe properly. When a cylinder member (210) is being held, in a specific direction of rotation about the axis of the mechanism, by a cylinder holding mechanism (120), an RFID chip (230) and an RFID reader (131) become communicable, making the piston drive mechanism operable. On the other hand, when the cylinder member (210) has been rotated by a specified angle from a specific direction, the RFID chip (230) and the RFID reader (131) become incommunicable, not making the piston drive mechanism operable. As a consequence, the piston drive mechanism is not driven when the cylinder holding mechanism (120) is not holding the medical liquid syringe properly.Type: GrantFiled: July 14, 2005Date of Patent: March 30, 2010Assignee: Nemoto Kyorindo Co., Ltd.Inventors: Shigeru Nemoto, Seiichi Ono, Masahiro Sakakibara

Publication number: 20090149744Abstract: A chemical solution injection system, wherein a RFID chip (230) is mounted on a chemical liquid syringe (200) in the state of being wrapped around the outer surface of the cylinder member (210) thereof. An amplification antenna (240) wrapped one turn around the outer surface of the cylinder member (210) is disposed at the front of the RFID chip (230) parallel with each other. Since the communication performance of the RFID chip is increased by the amplifying antenna, the RFID chip (230) of the chemical solution syringe (200) is allowed to satisfactorily communicate with the RFID reader (131) of injection head (110).Type: ApplicationFiled: November 17, 2005Publication date: June 11, 2009Inventors: Shigeru Nemoto, Seiichi Ono, Masahiro Sakakibara

Patent number: 7354964Abstract: The mixture solvent of dichlorimethane type, the TAC and the plasticizer are supplied into a dissolution tank, and stirred therein with a stirrer to obtain a dispersing solution. The dispersing solution is fed into a storing tank and further stirred therein. Then the dispersing solution is fed by a pump to a heat exchanger for the heating, and thereafter the stirring is made with a static mixer. The temperatures of the dope is measured at many measuring points. On the basis of the temperature distribution, the heat transmission conditions of the heat exchanger are adjusted. Then the dope is fed to a heat exchanger for cooling, to cool to at most the normal boiling point of the dope. Then the mixing is made with a static mixer. Thus the obtained dope is uniform.Type: GrantFiled: July 29, 2004Date of Patent: April 8, 2008Assignee: FUJIFILM CorporationInventors: Seiichi Ono, Yuji Suzuki, Hidekazu Yamazaki

Publication number: 20070276235Abstract: Upper transmitter 141 converts an electric signal transmitted from upper electronic device 101 into an ultrasonic signal and transmits the ultrasonic signal. First communication medium 146 transports the ultrasonic signal to lower receiver 142. Lower receiver 142 converts the received ultrasonic into an electric signal and transmits the electronic signal to lower electronic device 110. Thus, the electronic signal transmitted from upper electronic device 101 to lower electronic device 110 is modulated into the ultrasonic signal and then the ultrasonic signal is demodulated into the electronic signal, thereby the electronic signal cannot return to upper electronic device 101. Therefore, a data communication apparatus which can reliably regulate the direction of the transmitted electronic signal is provided.Type: ApplicationFiled: March 8, 2005Publication date: November 29, 2007Inventor: Seiichi Ono

Patent number: 7291135Abstract: A winged angled needle assembly has a hub to which a proximal end portion of an angled needle having a sharpened tip portion is joined and a pair of wings attached to both sides of the hub and further includes a fixing member attached so as to support the wings and an extensible, contractible needle guard disposed between the hub and the fixing member so as to connect these two members. The guard extends in the direction from the proximal end portion to the sharpened tip portion of the angled needle when extended, so that the tip portion can be encased in said guard simultaneously with pulling the angled needle out of an implanted port. The guard has an exposure prevention mechanism attached thereto and is externally stopped, so that the sharpened tip portion is kept from exposing once it is encased in the guard. The angled needle can have a length as required regardless of the length of the wings.Type: GrantFiled: August 18, 2005Date of Patent: November 6, 2007Assignee: Kawasumi Laboratories, Inc.Inventor: Seiichi Ono
