Beneficial effect:
New automatic Biochemical Analyzer of the present invention, avoided conventional automatic clinical chemistry analyzer to take up room larger, complex structure, the shortcoming that cost is high, miniaturization, the lightness of automatic clinical chemistry analyzer have been realized, greatly reduced the requirement of installing space, convenient transportation and installation, and automaticity is high.
Reagent-sample application and stirring system and purging system are of the present invention 2 large outstanding features:
(1) reagent-sample application and stirring system (being integrated sample pin application of sample and stirring system) stir reagent and sample by the shake of specimen needle self High Rotation Speed dexterously, make like this specimen needle one pin multiplex, structure is simpler and make biochemical analyzer operational efficiency higher.Specifically, be to adopt driven by motor specimen needle High Rotation Speed to make the syringe needle of specimen needle rock to stir sample and reagent, this novel rabbling mechanism makes equipment mechanism simple and stable more; Make novel rabbling mechanism and the specimen needle anticollision mechanism of specimen needle integrate simultaneously, make specimen needle can realize high-speed stirred function simultaneously; Integrated sample pin application of sample and stirring system also have collision prevention function; can protect specimen needle to exempt from shock; after specimen needle is impacted; specimen needle is raised; the change in location of optocoupler induction light barrier; provide electric signal to report to the police to the main control module of equipment (being automatic clinical chemistry analyzer device), this main control module can be according to the timely rollback of this alerting signal this integrated sample pin application of sample and stirring system, thereby plays the effect of protection specimen needle.Optocoupler is comprised of two parts, and transmitting terminal and receiving end have bar gap between two parts, when light barrier rises, just in being sandwiched in this gap, blocks the light path between transmitting terminal and receiving end.Transmitting terminal continues to send light signal, and when the light path of optocoupler is not blocked, receiving end can be received the signal that transmitting terminal sends, once light barrier rises, blocks light path, and receiving end cannot be received signal, sends alerting signal.Because specimen needle can be injected sample and reagent, also can stir evenly sample and reagent, and prevent specimen needle avoid collision, therefore, this mechanism gathers multi-function in integral whole, make automatic clinical chemistry analyzer device structure more compact small and exquisite, improved the work efficiency of equipment simultaneously, use also convenient.Therefore, this integrated sample pin application of sample and stir system design are simple and ingenious, have application of sample, stirring and collision prevention function concurrently, and significantly simplified apparatus structure, easy to implement, easy to use, can effectively improve test and analysis efficiency.
(2) core of wiper mechanism is improved and is to adopt novel straight-line motion mechanism, and simple in structure, stable and smooth operation, can significantly reduce straight-line motion mechanism manufacturing cost and manufacturing accuracy requirement.This straight-line motion mechanism adopts the contact movement of 3 pulleys 30 and slide rail 3 to realize rectilinear motion, 3 pulleys 30 are pushed down respectively to slide rail (23) from the both sides of slide rail 23, make portable plate (29) and to realize guide function at the upper upper and lower traveling priority of slide rail (23), the pulley of one side (30) can pass through eccentric nut (39) and regulate the dynamics and the gap that compress to realize adjusting and fixed function, this straight-line motion mechanism makes equipment mechanism simple and stable more, stable and smooth operation, can significantly reduce straight-line motion mechanism manufacturing cost and manufacturing accuracy requirement simultaneously.Between driving wheel (24) and engaged wheel (25), with Timing Belt (26), be connected and strain, gangbar is fixed on Timing Belt, the relative position of driving wheel and engaged wheel is constant, portable plate (29) just can drive Timing Belt (26) to realize straight-line driving by drive motor (21) like this, this simple and compact for structure, to installation and manufacturing accuracy, require low.The top of vertical plate (22) is provided with hall sensing plate (33), crashproof and positioning function is realized in position by the upper magnet (40) of installing of hall sensing plate (33) sensed activity plate (29), this structure has farthest been simplified mechanism, and by crashproof positioning function and the operability of this winding machine straight-line motion mechanism.Gland is installed in order to protect hall sensing plate (33) on hall sensing plate (33).Thereby, this novel linear motion novel structure and simple, not high to accuracy requirement, can flexible pulley with slide rail between coordinate tightness, and there is crashproof and positioning function, thereby feature richness.
In sum, new automatic Biochemical Analyzer of the present invention has novel integrated sample pin application of sample and stirring system, greatly dwindled the space of whole analyser, for huge contribution has been made in the miniaturization of instrument, in addition, adopt novel straight-line motion mechanism (being under the jurisdiction of purging system) to realize moving up and down of cleaning needle, simple in structure, easy to implement, cost is low, has reduced significantly the cost of analyser; Simultaneously, by the structure of reaction tray, integrated a plurality of reaction cup, coordinate stepper motor to drive the switching of the rotation realization response cup of reaction tray, then by XYZ three-axis moving system, realize sampling and the application of sample of specimen needle, whole system structure is very compact, operation is smooth, adopts sample storehouse and the agent bin of slide rail type, easy to operate, can hold multiple sample and plurality of reagents, for analytical test brings great convenience.Therefore, the whole process robotization of the operations such as sampling, application of sample, stirring, analyzing and testing, cleaning that new automatic Biochemical Analyzer of the present invention is integrated, automaticity is high, easy to operate, and cost is low, and testing efficiency is high, is easy to promotion and implementation.
