Abstract:
A multipurpose reagent system for rapid analysis of a whole blood sample allowing the determination of at least five classes of peripheral white blood cells, nucleated red blood cells, and lymphocyte immunophenotyping on automated hematology instrumentation. The multipurpose reagent system lyses red cells rapidly, while it concurrently fixes white cells and preserves surface antigens on lymphocytes. The multipurpose reagent system comprises from about 3 to 7 grams per liter of a non-quaternary ammonium salt, from about 0.04 to about 0.10 percent by volume of an aliphatic aldehyde with one to four carbons, from about 10 mM to about 20 mM of a non-phosphate buffer which is inert to the aliphatic aldehyde, and a sufficient amount of water to give a pH between 5.5 and 7.5 and an osmolality of between about 160 to about 310 mOsm per liter.
Abstract:
A method of testing a pumping system (10) including a pump cassette (12) effects pressurization of the system, with subsequent monitoring of any pressure loss in the system. This is achieved by closing any inlets (24) and outlets (26) of the cassette, and thereafter overpressurizing the cassette beyond its normal operating range. Pressure measurements are taken before and after a specified time interval, with any significant pressure loss indicating system leakage. In the preferred practice, the diaphragm (22) of the pump cassette is first subjected to cold flow, or "creep", thereby minimizing the influence of cold flow of the diaphragm on subsequent pressure measurement.
Abstract:
A method for the determination of the presence or amount of an analyte by monitoring a detectable label immobilized within an asymmetric membrane. A test mixture, comprising a test sample, an indicator reagent attached to a first specific binding pair member, and a capture reagent attached to a second specific binding pair member immobilized on a solid phase, is formed which is then captured within the asymmetric membrane thereby enabling analyte concentration to be determined.
Abstract:
The present invention (39) relates to a compression load cell (56) used to monitor pressure in a diaphragm cassette pumping system (10). A plunger (52) is axially slidable in a linear bearing (54) and has a first end in contact with the cassette (12) and the second end in contact with the load cell (56). The force signals have a direct relationship with the pressure in the cassette (12).
Abstract:
A dispensation module adapted to supply in order reaction trays each of which has a plurality of wells, and dispense a specimen to the reaction trays on the basis of set specimen information, a sample processing module adapted to dispense, on the basis of the set specimen information, a reaction reagent, which corresponds to a measurement item for a specimen, in the corresponding well, and transfer the specimen while retaining the same at a constant temperature, and a detecting module adapted to dispense a reaction measuring reagent in each well in the reaction trays on the basis of the set specimen information, and having a means for measuring the luminescent intensity are provided in an adjacently lines state. A walking beam mechanism, which is adapted to transfer reaction trays slidingly and intermittently, is employed for the transferring of the reaction trays in the sample processing module and detecting module. During the dispensation of reagent by the sample processing module, reagent dispensation nozzles are moved in the direction perpendicular to the reaction tray transfer direction and the dispensation is carried out within the stopping time of the intermittent sliding transfer of the reaction trays and at regular time intervals with respect to each well placed in a position of a set order, in a reaction tray. The measurement with the detecting module is conducted at regular time intervals correspondingly to each well placed in a position of the set order. The specimens dispensed in the wells in the reaction trays are subjected to operations from the dipensation of a reagent to the measurement of luminescent intensity under the same conditions at the same time intervals, so that all the specimens processed in large quantities can be measured accurately.
Abstract:
The present invention relates to a control system for use with an automated intravenous drug and fluid infusion system having plural pumping channels (4, 6, 8, 10) that operate independently for intravenously infusing drugs and fluid. The pumping channels (4, 6, 8, 10) are controlled by a microprocessor-based host controller (2) that monitors each of the channels concurrently. In an exemplary embodiment, the system functions include preventing priming of a channel unless verification is provided that the channel is not connected to a patient and initiating the priming of each of the pumping channels independently.
