As a result, the floor space is reduced, and the apparatus is further miniaturized.

Abstract: A sample analyzer comprises a reaction tray, a sample/reagent tray, and a probe. The reaction tray performs a first number of stops and rotations during an operating cycle, wherein the first number is configured to cause each of the reaction vessels to stop once at a position for the test before any of the number of the reaction vessels stops at the position for a second time. The sample/reagent tray rotates one of a sample container and reagent containers to a sample/reagent retrieving position during an operating cycle. The probe dispenses test sample(s), first reagent, and second reagent during different periods in different stop periods during an operating cycle. A method for analyzing samples is also disclosed.

Abstract: Dispensing devices and methods are provided. The dispensing devices can include a first dispensing station arranged on a periphery of a holding unit for dispensing a first reaction component, and a second dispensing station arranged on the holding unit for dispensing a second reaction component. The first reaction component and the second reaction component are dispensed. Operations on the holding unit are not affected by dispensing of the first reaction component, improving test efficiency. Because reaction containers do not need to be transferred out of the holding unit to dispense the second reaction component, test processes are simplified, In addition, the dispensing unit is not restricted to being arranged around the holding unit, and the first dispensing unit and second dispensing unit are arranged separately, so restriction of and interference with the dispensing units are avoided.

Abstract: The present invention discloses a code scanning device including a code scanner, a supporting member and a data processing and controlling unit. The unit is configured for receiving data information of a scanned code and determining whether or not the data information is correct. If correct, the unit stops scanning of the code scanner and controls the supporting member to move so that a next code is shifted to a scanning position. Wherein when the data information is incorrect or the unit fails to receive data information, the unit controls the code scanner to keep on scanning, and when scanning time exceeds a second predetermined time and the unit fails to receive correct data information, the unit stops scanning and controls the supporting member to move so that a next given code is shifted to the scanning position. The scanning device has an improved scanning speed and a high scanning reliability.

Abstract: A fully automatic biochemical analyzer and an analyzing method thereof are provided, in which the fully automatic biochemical analyzer includes two concentric reagent trays and two driving systems. The two driving systems respectively drive the two reagent trays to rotate, so the two reagent trays are capable of independent rotation, thereby avoiding various drawbacks resulting from required simultaneous rotation and stopping of the two reagent trays. The two reagent trays are concentrically disposed. Under a particular limitation of the table size, more reagent positions can be disposed, thereby increasing the number of items that can be analyzed at the same time by the analyzer.

Abstract: Disclosed is an automatic analysis apparatus and its operation method. The apparatus includes a reaction disk for carrying cuvettes and driving the cuvettes to rotate or to stop at predetermined positions, a reagent dispensing mechanism for injecting a reagent into the cuvettes, and a sample dispensing mechanism for injecting a sample into the cuvettes. The reagent dispensing mechanism includes a reagent needle, and the sample dispensing mechanism includes a sample needle. In each working cycle, the reaction disk is started to move and stopped at least twice respectively, and the reagent needle and the sample needle perform corresponding adding operations to the cuvette in different stopping stages. The approach may perform different tests in lower cost, can avoid restriction to the relative position of the needles, and is beneficial to the overall layout design of the apparatus.

Abstract: An automatic biochemical analyzing method is described, in which a row of reaction containers is cyclically arrayed such that an operating cycle is formed that is defined between dispensing the preceding sample and the sequent sample. In each cycle, the reaction containers are transferred so as to motivate at least one reaction container to pass across an optical detecting channel and cause the reaction containers to make an intermediate pause when no sample is dispensed. When the reaction containers pause, the sample is dispensed to a reaction container at a sample dispensing position. When the reaction containers are at the intermediate pause, the first reagent is dispensed to a reaction container at a first reagent dispensing position. In each reaction container, the operation cycle when the sample is dispensed follows the operation cycle when the first reagent is dispensed. An automatic biochemical analyzing apparatus is also disclosed.

Abstract: The present invention relates to an automatic chemistry analyzer comprising a reaction disk assembly (1), a sample and reagent disk assembly (2), a probe assembly (3) and a stirring assembly (4). A single probe (5) is used to dispense both the reagent and the sample into the reaction vessels. A pre-heating device disposed in the mechanical arm (6) for supporting the probe (5) pre-heats the reagent sucked into the probe to an appropriate temperature. The reaction vessels are disposable and may be replaced manually. The automatic chemistry analyzer may run single-reagent tests or double-reagent tests. According to the automatic chemistry analyzer of the present invention, the interval between injecting the first reagent of a test and injecting the sample of the same test may be 5.5 operation periods so that the first reagent in the reaction vessel may be maintained at or near an appropriate reaction temperature (37° C.).
