Patent number: 8414504Abstract: A blood test device using a laser as a puncture member. More specifically, in a blood test device using a laser as a puncture member, the skin can be fixed at a definite position by raising the punctured skin under negative pressure, and thus the skin is brought into close contact with a blood sensor and the laser is focused on the vicinity of the blood sensor face. Thus, it is possible to provide a blood test device of the laser puncture type in which the skin can be surely punctured while giving little pain to a patient.Type: GrantFiled: March 22, 2007Date of Patent: April 9, 2013Assignee: Panasonic CorporationInventors: Masaki Fujiwara, Yoshinori Amano, Takeshi Nishida, Toshihiro Akiyama, Masataka Nadaoka, Toshiki Matsumoto, Kenichi Hamanaka, Kiyohiro Horikawa, Koji Miyoshi

Patent number: 8394085Abstract: 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 is branched into laser beam paths by splitters and mirrors and pierces skin by applying the split beams to the same position on the skin. Since the skin is pierced by a laser beam with a low output, pain to the person can be reduced.Type: GrantFiled: March 22, 2007Date of Patent: March 12, 2013Assignee: Panasonic CorporationInventors: Kiyohiro Horikawa, Takeshi Nishida, Kenichi Hamanaka, Toshihiro Akiyama, Koji Miyoshi, Yoshinori Amano

A blood reservoir defined by a substrate hole formed in the substrate. A part of a spacer hole in the spacer and connected to the substrate hole, and a cover hole formed in the cover is connected to the spacer hole. A supply passage is defined by another part of the spacer hole that communicates with the blood reservoir portion, and detection electrodes are formed in the supply passage.

Publication number: 20110237978Abstract: 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. Thus, the skin rises and comes into contact with a second skin contact sensor. After piercing into the skin, the negative pressure supply is once ceased. Next, the negative pressure is applied again for a definite period of time. Thus, the opening in the skin is broadened, which facilitates the flow out of the blood.Type: ApplicationFiled: June 3, 2011Publication date: September 29, 2011Applicant: PANASONIC CORPORATIONInventors: Masaki FUJIWARA, Yoshinori AMANO, Kenichi HAMANAKA, Motonori UCHIYAMA, Masataka NADAOKA, Toshihiro AKIYAMA, Koji MIYOSHI

Patent number: 7976478Abstract: 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: GrantFiled: March 22, 2007Date of Patent: July 12, 2011Assignee: Panasonic CorporationInventors: 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: 20060133956Abstract: A test strip holder comprises a rectangular base having a concave part on its upper surface, arid a slidable moving part that is slidably fitted to the concave part of the base. When measuring the test strip, the test strip is reliably held between the base and the slidable moving part. After measurement, the test strip is ejected semiautomatically from the test strip holder by sliding of the slidable moving part with respect to the base. Therefore, the test strip after measurement, which has health problem and risk of infection, can be semiautomatically discarded without touching the test strip.Type: ApplicationFiled: December 8, 2005Publication date: June 22, 2006Inventor: Kenichi Hamanaka
