Patent number: 8596150Abstract: An inlet (37a) of a capillary tube channel that feeds a liquid from a mixing cavity (39) to measurement spots is formed near one (4) of the wall surfaces of the upper and lower surfaces of the mixing cavity (39) situated in a direction of oscillation for mixing. On the other wall surface (3), a level difference (39a) is formed such that an inner gap is larger than an outer gap in the mixing cavity (39), so that a solution is reliably fed from the mixing cavity to the measurement cells.Type: GrantFiled: June 30, 2009Date of Patent: December 3, 2013Assignee: Panasonic CorporationInventors: Hiroshi Saiki, Tomohiro Kijima, Kenji Ishibashi, Kouzou Tagashira

Patent number: 8512638Abstract: A microchip having an inlet (14) for collecting a liquid sample; at least one capillary cavity (4) capable of collecting a specific amount of the liquid sample through the inlet (14) by using capillary force; and a holding chamber (5) communicating with the capillary cavity (4) and receiving the sample liquid in the capillary cavity (4) transferred by centrifugal force generated by rotation about an axis. The capillary cavity (4) interconnecting the inlet (14) and the holding chamber (5) has, in one side face of the capillary cavity (4), cavities (15, 16) not generating capillary force and communicating with the atmosphere, and this prevents mixing of air bubbles into the capillary cavity (4).Type: GrantFiled: October 23, 2007Date of Patent: August 20, 2013Assignee: Panasonic CorporationInventor: Hiroshi Saiki

Publication number: 20110117665Abstract: An analyzing device includes: an operation cavity (245) that is adjacent to a first reserving cavity (243) retaining a sample liquid, in a circumferential direction of rotational driving; a connecting section (255) provided on a side wall of the first reserving cavity (243) to suck the sample liquid by a capillary force and transfer the sample liquid to the operation cavity (245); and second reserving cavities (247, 248) that are disposed outside the operation cavity (245) in the circumferential direction of the rotational driving and communicate with the outermost position of the operation cavity (245) through a connecting passage (256). The connecting section (255) is circumferentially extended farther than the liquid level of the sample liquid retained in the first reserving cavity (243). Thus it is possible to reduce the quantity of the sample liquid, eliminate irregular agitation of a sample liquid and reagents, and reduce the size of an analyzing device.Type: ApplicationFiled: June 30, 2009Publication date: May 19, 2011Applicant: PANASONIC CORPORATIONInventors: Hiroshi Saiki, Hirofumi Sugimoto, Seiji Sogabe

Publication number: 20110058985Abstract: An analysis device comprises a separation chamber for separating a sample solution into a solution component and a solid component, a holding channel, a mixing chamber connected to the holding channel, an overflow channel connected between the holding channel and the separation chamber, a sample overflow chamber into which the sample solution remaining in the separation chamber is discharged, and a joint channel connecting the separation chamber and the sample overflow chamber. After the separated solution component fills the overflow channel with priority, the separated solid component is transferred to the holding channel via the overflow channel, and a predetermined amount of the solid component is measured. The solid component in the holding channel is transferred to the mixing chamber by a centrifugal force, and simultaneously, the sample solution remaining in the separation chamber is discharged to the sample overflow chamber by the siphon effect of the joint channel.Type: ApplicationFiled: November 12, 2010Publication date: March 10, 2011Inventors: Hiroshi SAIKI, Masanori Tanaka

Patent number: 7897398Abstract: A device for analysis used for transferring a solution to a measurement spot 38 by a centrifugal force and reading in which a reaction liquid located at the measurement spot 38 is optically accessed. An operation cavity 30 and a receiving cavity 32 are arranged from the upstream side to the downstream side of the transfer. The operation cavity 30 and the receiving cavity 32 communicate with each other via a connection section 59 to transfer the solution of the operation cavity 30 to the receiving cavity 32. The connection section 59 is located inside the liquid level of a diluted solution retained in the operation cavity 30, relative to a rotation axis 102.Type: GrantFiled: July 25, 2008Date of Patent: March 1, 2011Assignee: Panasonic CorporationInventor: Hiroshi Saiki

Publication number: 20100323454Abstract: A measurement cell (40a) is formed so as to extend in a direction along which a centrifugal force is applied, and a capillary area (47a) to which a sample liquid is sucked by a capillary force is formed on one of the side walls of the measurement cell (40a), the side walls being arranged in a rotational direction. The capillary area (47a) extends from the outer periphery position to the inner periphery of the measurement cell (40a), thereby reducing the size of an analyzing device. Further, the sample liquid in the measurement cell (40a) is sucked to the capillary area (47a) by slowing or stopping a rotation, and then the rotation is accelerated to return the sample liquid in the capillary area (47a) to the measurement cell (40a). It is therefore possible to achieve a sufficient agitating effect and conduct measurement with a small quantity of sample liquid.Type: ApplicationFiled: February 4, 2009Publication date: December 23, 2010Applicant: PANASONIC CORPORATIONInventors: Hiroshi Saiki, Kouzou Tagashira, Hirofumi Sugimoto, Kenji Watanabe, Kenji Ishibashi, Takuji Miyata

Publication number: 20100281961Abstract: A protective cap 2 is engaged with a latch 10 of a diluent container 5 so as to fix the diluent container 5 at a liquid holding position of a diluent container containing section 11. The engagement is released when the protective cap 2 is set to an open position against the engagement so as to expose an inlet 13. When the protective cap 2 is shifted from the open position to a closed position, the protective cap 2 pushes the diluent container 5 into a liquid discharge position. Thus, it is possible to preserve a diluent for a long period of time and to easily open the diluent container 5 without having to complicate the structure of an analysis apparatus.Type: ApplicationFiled: October 27, 2008Publication date: November 11, 2010Applicant: PANASONIC CORPORATIONInventors: Hiroshi Saiki, Yoshiyuki Fujii, Nobuyasu Higashi, Masaaki Kitoh, Kenji Okada, Hirofumi Sugimoto
