Patent number: 10441731Abstract: A pharmaceutical injection device may comprise a main body case having a cartridge holder, a piston that pushes out the pharmaceutical of a pharmaceutical cartridge held in the cartridge holder, a light emitting component, a light receiving component, and a controller. The light emitting component may shine light of different colors on the pharmaceutical cartridge disposed in the cartridge holder. The light receiving component receives light that has been shined from the light emitting component onto the pharmaceutical cartridge and reflected by the pharmaceutical cartridge. The controller may shine from the light emitting component and identify the type of pharmaceutical cartridge.Type: GrantFiled: November 25, 2014Date of Patent: October 15, 2019Assignee: PHC HOLDINGS CORPORATIONInventors: Tooru Aoki, Kenji Murakami, Takahiko Tanida, Hiroshi Suzuki, Shinsuke Hata

Patent number: 9956343Abstract: The pharmaceutical injection device of the present invention comprises a cartridge holder, a main case, a piston, a motor, an opening component, an open/closed detection switch, and a controller. The motor drives the piston in either an insertion direction in which the piston is inserted into a pharmaceutical cartridge, or a pull-out direction in which the piston is pulled out of the pharmaceutical cartridge. The opening component opens the cartridge holder in conjunction with the movement of the piston in the pull-out direction. The open/closed detection switch detects whether the cartridge holder is open or closed. When the open/closed detection switch detects that the cartridge holder is open, the controller controls the motor so as to stop the piston.Type: GrantFiled: December 13, 2013Date of Patent: May 1, 2018Assignee: Panasonic Healthcare Holdings Co., Ltd.Inventors: Kenji Murakami, Masato Kagiyama, Tooru Aoki, Yoshihiro Kataoka, Takahiko Tanida, Hiroshi Suzuki

Patent number: 8481330Abstract: Disclosed is a method for analyzing a sample solution, including introducing a sample solution 50 through a sample introduction part 6 and developing the sample solution 50 to a developing layer 2 through a capillary phenomenon to analyze an analyte contained in the sample solution 50, the sample introduction part 6 being provided on one side of a test strip 100 and the developing layer 2 being provided on the other side of the test strip 100, wherein the test strip 100 is disposed in such a development posture that the downstream region of the developing layer faces downward during the development. By this method, the developing rate is less susceptible to the viscosity of the sample solution 50 and thus has a small difference even among sample solutions 50 differing in viscosity. As a result, the analytical accuracy and reliability can be improved.Type: GrantFiled: January 9, 2009Date of Patent: July 9, 2013Assignee: Panasonic CorporationInventors: Yoko Matsuda, Mie Takahashi, Masahiro Aga, Hideyuki Kurokawa, Takahiko Tanida, Ryosuke Yamada

Patent number: 8345249Abstract: Provided is a liquid sample analyzing method for analyzing an analyte in a liquid sample by using a test piece (1) on which overflow blocking lines (7) are formed to prevent the liquid sample from flowing to the outside from a passage region (3a) of an extended layer (3). In a state in which the liquid sample is not extended in the passage region (3a) of the extended region (3), the test piece (1) is measured so as to cross the passage region (3a) of the extended layer (3) and the overflow blocking lines (7). Thus in a state in which a difference in brightness is large between the passage region (3a) of the extended region (3) and the overflow blocking lines (7), it is possible to properly recognize the boundary portions between the passage region (3a) of the extended region (3) and the overflow blocking lines (7).Type: GrantFiled: March 26, 2009Date of Patent: January 1, 2013Assignee: Panasonic CorporationInventors: Hideyuki Kurokawa, Koji Miyoshi, Masahiro Aga, Kenji Murakami, Takahiko Tanida, Ryosuke Yamada
