20080220464 | BLOOD TEST INSTRUMENT USING A DISPOSABLE CARTRIDGE - A blood test instrument using a disposable cartridge and a method of measuring a blood sample using the instrument are disclosed. The instrument includes a cell counting station for counting blood cells by electrical resistance measurement, a pressure actuating component adapted to apply a pressure alternately on two flexible receptacles of a disposable cartridge removably placed in the instrument to cause flowing of a mixture of a blood sample and a liquid agent between the two receptacles to obtain proper mixing, and a conduit adapted to deliver the mixture to the cell counting station for counting. After measuring the blood sample, the instrument withdraws a washing liquid contained in another receptacle of the disposable cartridge and uses the washing liquid to clean the instrument and to deliver the mixture back to the cartridge for disposal. | 09-11-2008 |
20100101318 | DEVICE FOR EXTRACTION OF A PARTIALLY DEFINED SAMPLE VOLUME FROM A LARGER VOLUME - The invention provides a device for extraction of a defined sample volume from a larger sample volume. The device includes a body having a reference surface and a measuring cavity extending from a part of the reference surface into the body, thereby forming at least one opening plane substantially uniform with the reference surface, the body being adapted for reception of an excess sample volume at the cavity and elimination of sample above the reference surface to leave in the cavity a measured sample volume having the defined volume. An information carrier is applied to or arranged for distribution with the device, having direct or indirect volume information about the defined volume established for the cavity. The invention also relates to a method for determining the volume of such a cavity, to a set of at least two such devices, to a method for dilution of at least two liquid samples by the use of at least two such devices, to an analytic instrument, to a method for operating such an instrument, to a system including the device and the instrument, and to a method for operating the system. | 04-29-2010 |
20100221150 | APPARATUS FOR FILLING A SAMPLE VOLUME DEFINING DEVICE - An apparatus for filling a sample volume defining device for separating at least one small defined volume of a liquid sample from a relatively larger undefined volume of said sample, said device including a first body and a second body movable relative to each other, whereby said first body has at least one cavity in a surface thereof, said at least one cavity having said defined volume. One of said first or said second body has at least one inlet opening adapted to be placed in a drop of the liquid sample. A defined channel is provided between said first and second body, which channel has fluid connection with said at least one opening and at least beyond said at least one cavity whereby the dimensions of said channel being such that said channel and said at least one cavity is filled with said liquid sample. | 09-02-2010 |
20110039298 | METHOD OF MEASURING BLOOD SAMPLE ON BLOOD TEST INSTRUMENT USING A DISPOSABLE CARTRIDGE - A blood test instrument using a disposable cartridge and a method of measuring a blood sample using the instrument are disclosed. The instrument includes a cell counting station for counting blood cells by electrical resistance measurement, a pressure actuating component adapted to apply a pressure alternately on two flexible receptacles of a disposable cartridge removably placed in the instrument to cause flowing of a mixture of a blood sample and a liquid agent between the two receptacles to obtain proper mixing, and a conduit adapted to deliver the mixture to the cell counting station for counting. After measuring the blood sample, the instrument withdraws a washing liquid contained in another receptacle of the disposable cartridge and uses the washing liquid to clean the instrument and to deliver the mixture back to the cartridge for disposal. | 02-17-2011 |
20110313682 | ANALYTICAL INSTRUMENT PROVIDING CORRECTED SAMPLE VOLUME DEPENDENT PARAMETER - The invention provides a device for extraction of a defined sample volume from a larger sample volume. The device includes a body having a reference surface and a measuring cavity extending from a part of the reference surface into the body, thereby forming at least one opening plane substantially uniform with the reference surface. An information carrier is applied to or distributed with the device, having direct or indirect volume information about defined volume established for the cavity. The invention also relates to a method for determining the volume of such a cavity, to a set of at least two such devices, to a method for dilution of at least two liquid samples by using at least two such devices, to an analytic instrument, to a method for operating such an instrument, to a system including the device and the instrument, and to a method for operating the system. | 12-22-2011 |
20120276582 | DISPOSABLE CASSETTE AND METHOD OF USE FOR BLOOD ANALYSIS ON BLOOD ANALYZER - A disposable cassette for blood analysis includes a housing having an upper panel and a sampling section having a filling inlet; at least one pair of chambers in a form of depression of the upper panel of the housing and sealed by a diaphragm; portions of the diaphragm over the chambers being flexible; and one or more channels adapted to interconnect the pair of chambers; one of the chambers containing a predetermined amount of a reagent for blood analysis; and a sample outlet disposed next to and connected to the chamber containing the reagent, the sample outlet including an outlet cavity recessed from the upper panel, a divider disposed therein, and a cover covering the outlet cavity; the sample outlet sealing the reagent to the chamber containing the reagent. Further disclosed is the method of using the disposable cassette for measurements of hematology parameters on a blood analyzer. | 11-01-2012 |
