20100216183 | MICROBIAL DETECTION APPARATUS, MICROBIAL DETECTION METHOD, AND SAMPLE CONTAINER USED THEREIN - The sample container has a two-layer membrane filter comprising a first layer as an upper layer serving as a hydrophilic membrane filter and a hydrophobic membrane filter as an underlying second layer capable of filtering an aqueous solution without the use of a wetting agent and by means of a formed negative pressure. Using this sample container, a large amount of an aqueous sample solution is filtered by means of a negative pressure formed by a suction portion to capture microbes in the aqueous sample solution by the hydrophilic membrane filter. Then, the negative pressure is restored to normal pressure, and a microbial dissolution solution is then added to the membrane filter to retain the microbial dissolution solution for a given time on the hydrophobic membrane filter. Then, the microbial dissolution solution is dispensed to a reaction container containing a luminescent reagent, and luminescence is detected to detect the microbes. | 08-26-2010 |
20110159536 | DEVICE FOR CAPTURING OBJECT AND METHOD FOR USING THE SAME - An object of the present invention is to provide an object-capturing device which accurately detects objects such as microorganisms captured at a test site. The object-capturing device of the present invention includes a capturing dish holding a carrier, which captures objects (microorganisms), on a first side of the capturing dish. The capturing dish has a through hole extending from the first side to a second side of the capturing dish. The object-capturing device is used in a way such that, after the objects are captured with the carrier directed upward, the carrier is directed downward and reagents for detecting the objects are contacted with the objects captured on the carrier through the through hole. | 06-30-2011 |
20110171670 | REAGENT OPEN MECHANISM OF LUMINESCENCE MEASUREMENT SYSTEM AND OPEN NEEDLE CONTROL METHOD IN REAGENT OPEN MECHANISM - A reagent open mechanism of the luminescence measurement system comprises a triaxial actuator and a reagent dispensing nozzle which is driven by the triaxial actuator. A reagent cartridge where a reagent to be divided by the reagent dispensing nozzle is filled in a concave and the opening of the concave is sealed by an aluminum sheet can be set in. This reagent open mechanism comprises an open needle which is driven by the triaxial actuator and makes a hole in the aluminum sheet and a fixation block between the reagent dispensing nozzle and the open needle which arranges the reagent dispensing nozzle and the open needle in such location that the reagent dispensing nozzle or the open needle does not contact with a structure including the reagent cartridge in a Z-axis operation during opening time or reagent dividing and dispensing time. | 07-14-2011 |
20110171725 | MECHANISM AND METHOD OF PREVENTING SUCTION AIR FROM LEAKING DURING FILTRATION OF CAPTURING CARRIER SOLUTION - A mechanism for preventing suction air from leaking uses a capturing carrier cartridge that includes a cartridge main body and a filter fixing ring. The cartridge main body includes a storage portion for storing a capturing carrier solution and a filter mounting portion where a filter for filtering the capturing carrier solution is disposed. The filter fixing ring covers the filter mounting portion, positions the filter, and sucks and filters the capturing carrier solution from a lower surface thereof. The mechanism includes a cartridge holder and a suction head. The cartridge holder includes an opening that includes the filter mounting portion of the capturing carrier cartridge, and a holding portion that holds the storage portion. The suction head sucks the capturing carrier solution through the lower surface of the filter fixing ring while applying pressure to press the filter fixing ring against the filter mounting portion. | 07-14-2011 |
20110176975 | REAGENT SPLITTING / DISPENSING METHOD BASED ON REAGENT DISPENSING NOZZLE AND REAGENT SPLITTING / DISPENSING MECHANISM - The present invention provides a reagent splitting/dispensing method that can prevent contamination of an operation fluid when a reagent dispensing nozzle is in a waiting state and prevent falling of a droplet. The reagent splitting/dispensing method includes a waiting process of disposing a first air layer between an interface of the operation fluid and a nozzle tip end in the reagent dispensing nozzle, a first moving process of moving the reagent dispensing nozzle to the position right above the reagent, a second moving process of depositing the nozzle tip end in the reagent, a reagent splitting process of filling the reagent into the reagent dispensing nozzle, a third moving process of evacuating the tip end of the reagent dispensing nozzle from the reagent, a reagent protecting process of disposing a second air layer in the nozzle tip end, a fourth moving process of moving the reagent dispensing nozzle to the reagent dispensation position, a reagent dispensing process of ejecting the split reagent, an operation fluid protecting process of disposing the first air layer in the nozzle tip end, after dispensing the reagent, and a fifth moving process of evacuating the reagent dispensing nozzle to the waiting position, in a state where the first air layer is disposed in the nozzle tip end. | 07-21-2011 |
20110183408 | REAGENT CARTRIDGE FOR MICROORGANISM DETECTION APPARATUS - A reagent cartridge for a microorganism detection apparatus includes a plurality of reagent vessels, a support plate, and side plates, wherein the reagent vessels are integrally connected with each other in parallel by the support plate, and a group of the plurality of the reagent vessels is surrounded by the side plates; the reagent cartridge further includes an independent reagent vessel instead of at least one of the plurality of the reagent vessels and separately therefrom; and an engagement portion, wherein the engagement portion engages the independent reagent vessel in the engagement portion so as to be universally attached and detached, and to be in parallel with the plurality of the reagent vessels. | 07-28-2011 |
20130139898 | REAGENT SPLITTING/DISPENSING METHOD BASED ON REAGENT DISPENSING NOZZLE AND REAGENT SPLITTING/DISPENSING MECHANISM - A reagent splitting/dispensing method based on a reagent dispensing nozzle controls a split or dispensation amount of reagent, includes a waiting process of disposing a first air layer between an interface of the operation fluid and a nozzle tip end in the reagent dispensing nozzle; a first moving process of moving the reagent dispensing nozzle to a position above the reagent to be split; a second moving process of depositing the nozzle tip end in the reagent; an air layer adjusting process of increasing the occupation amount of the operation fluid in the reagent dispensing nozzle and decreasing the occupation amount of the first air layer, between the first moving process and the second moving process; and a reagent splitting process of decreasing the occupation amount of the operation fluid in the reagent dispensing nozzle and filling the reagent into the reagent dispensing nozzle from the nozzle tip end. | 06-06-2013 |
