20100112681 | MICROCHIP FLUID CONTROL MECHANISM - Compressed gas is supplied from above to a specimen vessel having an open top. Transfer channels to reaction vessels are provided under a microchip and transfer channels extending from the reaction vessels are provided on the microchip. Transfer element is provided outside the microchip so as to supply the compressed gas from a member (cover) holding the microchip. | 05-06-2010 |
20100221814 | TEMPERATURE CONTROL METHOD AND SYSTEM - For heating or cooling a sample contained in a vessel portion through a heat transfer member held in contact with the vessel portion, there is used the vessel portion, which has a part formed of an elastic member, expands and contracts for injection and discharge of the sample, is closed other than a connecting port with a channel connected to the vessel, and expands and contracts for injection and discharge of the sample. The vessel portion expands correspondingly to the injection when the sample is injected through an inflow path serving as the channel into the vessel portion contracting in a non-contacting state with the heat transfer member. A predetermined amount of sample is injected into the vessel portion so as to expand the vessel portion, and the vessel portion comes into contact with the heat transfer member. The vessel portion is heated or cooled through the heat transfer member. | 09-02-2010 |
20100323432 | SAMPLE PROCESSING DEVICE FOR MICROCHIP - A sample processing device for a microchip, including: a sample vessel for packing a sample therein; and a reaction vessel which is continuous with the sample vessel through a channel, and to which the sample is sequentially delivered to be packed and mixed therein, in which the sample is repeatedly delivered between the sample vessel and the reaction vessel through the channel so that the sample is stirred and mixed. | 12-23-2010 |
20110000561 | FLOW PASSAGE CONTROL MECHANISM FOR MICROCHIP - A channel control mechanism for a microchip has a laminated structure formed of members including elastic members, and includes: a sample reservoir for packing a sample therein; a reaction reservoir in which mixture and reaction of the sample are performed; and a channel formed in a middle layer of the laminated structure, for bringing the sample reservoir and the reaction reservoir into communication with each other. The channel control mechanism performs the reaction and analysis in such a manner that the sample is delivered into the reaction reservoir through the channel. A shutter channel (pressurizing channel) is provided in a layer different from a layer in which the channel is formed so that the pressurizing channel partially overlaps the channel. The channel is closed through applying a pressurized medium to the shutter channel (pressurizing channel), and the channel is opened through releasing a pressure of the pressurized medium. | 01-06-2011 |
20110002812 | SAMPLE PACKING DEVICE - Provided is a sample packing device for packing a sample with respect to a microchip for performing reaction of a micro component contained in the sample, the microchip at least including: a sample reservoir; a reaction reservoir; and a channel connected between the sample reservoir and the reaction reservoir, in which a package including a sample chamber packed in advance with the sample is mounted on the microchip so as to pack the sample in the sample chamber into the sample reservoir. | 01-06-2011 |
