Publication number: 20110032525Abstract: 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: ApplicationFiled: March 26, 2009Publication date: February 10, 2011Applicant: PANASONIC CORPORATIONInventors: Hideyuki Kurokawa, Koji Miyoshi, Masahiro Aga, Kenji Murakami, Takahiko Tanida, Ryosuke Yamada

Publication number: 20100262039Abstract: A blood test apparatus having a simple constitution whereby stable measurement can be conducted by surely sampling the blood in an amount being small but sufficient for the test without placing too much burden on a patient. When a first skin contact sensor of this apparatus detects the skin, driving of a negative pressure unit is initiated (time point 166a). Thus, the skin rises and comes into contact with a second skin contact sensor (time point 166b). After piercing into the skin at time point 166c, the negative pressure supply is once ceased. Next, the negative pressure is applied again at time point 166d for a definite period of time. Thus, the opening in the skin is broadened, which facilitates the flow out of the blood (16).Type: ApplicationFiled: March 22, 2007Publication date: October 14, 2010Applicant: MATSUSHITA ELECTRIC INDUSTRIAL CO., LTD.Inventors: Masaki Fujiwara, Yoshinori Amano, Kenichi Hamanaka, Motonori Uchiyama, Masataka Nadaoka, Toshihiro Akiyama, Koji Miyoshi

Publication number: 20100234835Abstract: A laser perforation device that has a simple structure and with which pain to a person in skin perforation is reduced. In the device, a laser beam emitted from a laser emitting device (33) is branched into laser beam paths by splitters (170a, 170b, 170c) and mirrors (171a, 171b, 171c) and pierces skin (13) by applying the split beams to the same position (177) on the skin (13). Since the skin is pierced by a laser beam with a low output, pain to the person can be reduced.Type: ApplicationFiled: March 22, 2007Publication date: September 16, 2010Applicant: MATSUSHITA ELECTRIC INDUSTRIAL CO., LTD.Inventors: Kiyohiro Horikawa, Takeshi Nishida, Kenichi Hamanaka, Toshihiro Akiyama, Koji Miyoshi, Yoshinori Amano

Publication number: 20100210028Abstract: In a biosensor for measuring the concentration of an object to be analyzed by optical signal detection, when a liquid sample is supplied to a supply part (12), the liquid sample is developed in a development part (13), and color development takes place in a reaction part (14) depending upon the concentration of the object to be analyzed. The absorbance of the reaction part (14) is read. In this case, the amount of the liquid sample supplied into the supply part (12) can be measured by reading the development speed.Type: ApplicationFiled: September 25, 2008Publication date: August 19, 2010Applicant: PANASONIC CORPORATIONInventors: Koji Miyoshi, Masahiro Aga, Takahiko Tanida, Ryosuke Yamada, Hideyuki Kurokawa, Yoko Matsuda

Publication number: 20100191147Abstract: A piercing device and a blood inspection device that have increased safety. The piercing device (111) has a piercing button (113) placed on the front surface of a first case (112a), a base (114) being a piecing opening provided projecting from the front surface of the first case (112a), and a laser emission device (115) received in the first case (112a). First safety means (117) prevents emission of a laser beam (115a) to the outside when the first case (112a) and a second case (112b) are superposed on each other. When the base (114) is depressed after the second case (112b) is moved from the superposed state where the second case (112b) is superposed on the first case (112a) to a non-superposed state where the second case (112b) is not, a switch (114b) detects the depression of the base (114) and second safety means (118) to enable depression of the piercing button (113).Type: ApplicationFiled: July 31, 2008Publication date: July 29, 2010Applicant: PANASONIC CORPORATIONInventors: Koji Miyoshi, Takeshi Nishida, Yoshinori Amano, Toshiki Matsumoto, Masataka Nadaoka
