| 20110097817 | REACTION DEVICE FOR ANALYZING BIOLOGICAL SAMPLES AND RELATIVE METHOD - A reaction device and method provided with a reaction cell in which, in sequence, a plurality of biological samples, liquid, semi-liquid or mixed, of analogous or different type, are subjected to a reaction for a determinate analysis. The device comprises a first dispenser element which introduces a predetermined quantity of the biological sample inside the cell; a plurality of microvalve dispensers, each of which nebulizes a determinate microvolume of a desired reagent inside the cell, wherein the type of reagent and the amount of the microvolume of reagent are chosen as a function of the specific reaction to be carried out, selected from a group comprising reactions for analyses of a chemical-biological type, such as immunological or coagulative reactions, or of a chemical-physical type; a mixer element which mixes the biological sample with the selected reagent; a second dispenser element which sends to analytical measurement a determinate quantity of the biological sample after reaction with the selected reagent; washing members and discharge members, able respectively to wash the inside of the cell and to discharge the content of the cell, so as to prepare the cell for a subsequent reaction; an electronic processor which commands and controls, in the desired times and modes, the functioning of both the first dispenser element which dispenses the sample, of the microvalve dispensers which dispense the reagents, and of the mixer element, and also of the second dispenser element which sends the reacted sample for measurement, and of the washing members and discharge members, as a function of the type of reaction to be performed and the type of biological sample to be analyzed, so that their functioning is synchronized and automated according to pre-determined memorized reaction programs, selectable by an operator. | 04-28-2011 |
| 20110070126 | UNIT FOR THE LOADING AND IDENTIFICATION OF BIOLOGICAL SAMPLES AND INTEGRATED MACHINE COMPRISING SAID LOADING AND IDENTIFICATION UNIT - A unit for the loading and identification of different biological samples, liquid, semi-liquid or mixed, to be subjected to one or more different analyses of chemical-biological type, such as immunological or coagulative reactions, or chemical-physical type, comprising: a plurality of support members able to carry a plurality of test tubes each one containing a determinate biological sample to be analyzed; a plurality of identification means based on optical or optoelectronic recognition, which carry information, univocal for a determinate sample or a determinate group of samples to be analyzed and which are directly associated with each of the test tubes and/or with each of the support members so that said information is transmitted to an electronic processing unit for the selection of a determinate test tube depending on the type of biological sample and the analysis to be carried out; a pick-up member able to pick up, on the basis of determinate commands received from the electronic processing unit, a portion of the sample contained in the determinate test tube and to dispense and move the portion of the sample to send the portion of the sample to the reactions provided in a reaction unit and to the subsequent analytical measurements in a measuring unit. | 03-24-2011 |
