It is to protect branch that specimen needle, which cleans waste liquid third branch A3 and reagent needle cleaning waste liquid third branch A3 ',.Sample Needle cleans waste liquid third branch A3 and reagent needle cleaning waste liquid third branch A3 ' is directly connected to waste liquid bottle 33.When water wash system, acid It washes system and when waste discharge system breaks down, can prevent water or acid wash liquid from overflowing, water and acid wash liquid are logical by dead weight Specimen needle cleaning waste liquid third branch A3 and the cleaning waste liquid third branch A3 ' discharges of reagent needle are crossed, to prevent water or acidity from washing Hydrorrhea goes out to cause instrument damage.
In the above-described embodiments, include accordingly reagent disc 31 and general liquid disk 32.Due to reagent disc 31 and general liquid disk 32 standing temperature are 2-8 DEG C, and the steam in disk in air can form cold water drenching, therefore the reagent disc 31 and general liquid disk 32 are arranged It is cleaned on waste liquid third branch A3 or reagent needle cleaning waste liquid third branch A3 ' in specimen needle, the cold water drenching formed in disk passes through Specimen needle cleans waste liquid third branch A3 or reagent needle cleaning waste liquid third branch A3 ' finally flows into waste liquid bottle 33.
In Fig. 1 and embodiment illustrated in fig. 3, specimen needle cleaning waste liquid third branch A3 and reagent needle cleaning waste liquid the Three branch A3 ' are incorporated in rear end in the 4th branch A0, the reagent disc 31 and the general liquid disk 32 setting after merging the On four branch A0.
A kind of workflow of this system is explained in detail below:
1, sample and reagent are dispensed
When sample dispenses, the first solenoid valve 22 is closed, and specimen needle dispensing pump 23 is driven by motor, is drawn by specimen needle 24 Sample and dispensing sample;
When reagent dispenses, second solenoid valve 28 is closed, and reagent needle dispensing pump 26 is driven by motor, is drawn by reagent needle 27 Reagent and dispensing reagent;It should be understood that dispensing general liquid if necessary, then one of agent dispensing unit is logical for distributing With liquid, likewise, second solenoid valve 28 is closed, general liquid needle dispensing pump is driven by motor, and general liquid is drawn by general liquid needle With the general liquid of dispensing.
2, specimen needle is rinsed and reagent needle rinses
When water level reaches the first water level in clean water pot 1, inlet valve 4 is opened, and intake pump 3 is started into water;Clean water pot 1 When middle water level rises to the second water level, intake pump 3 is closed, and stops water inlet, and inlet valve 4 is closed.Water level rises in clean water pot 1 When third water level, water-level alarm needs artificially to check.When being rinsed in specimen needle, the first solenoid valve 22 is opened, and is rinsed in specimen needle Water pump 25 starts, and high pressure water is flowed out by specimen needle dispensing pump 23 from 24 inner cavity of specimen needle, 24 inner wall of specimen needle is rinsed, from sample The water that needle 4 flows out, by specimen needle rinse bath 6, and has cleaned the outer wall of specimen needle 24.When being rinsed in reagent needle 27, the second electricity Magnet valve 28 is opened, and flush water pump 29 starts in reagent needle, and high pressure water is flowed out by reagent needle dispensing pump 26 from 27 inner cavity of reagent needle. 27 inner wall of wash reagent needle;The water flowed out from reagent needle 27, by reagent needle rinse bath 5, and has cleaned the outer wall of reagent needle 27.
When being rinsed outside specimen needle 24, flush water pump 21 starts outside specimen needle, and high pressure water flow is to specimen needle rinse bath 6, in sample Specimen needle 24 is by compressing repeatedly in this needle rinse bath 6, to clean up the inner and outer wall of specimen needle 24.
3, specimen needle pickling and reagent needle pickling
When acid wash liquid liquid level is less than the liquid level of the second liquid level sensor 10 in acid wash liquid bottle, the second liquid level sensor 10 can alarm, and prompting needs to add acid wash liquid;After adding washing lotion, liquid level warning can be cancelled automatically.Specimen needle 24 carries out pickling When, corresponding acid wash liquid pump 7 starts.Washing lotion is flowed by acid wash liquid pump 7 in specimen needle rinse bath 6, and specimen needle 24 exists Compressing 10 times repeatedly in specimen needle rinse bath 6, to achieve the purpose that acid specimen needle 24;When reagent needle acidity, corresponding acid Property lotion pumps 7 are started.Washing lotion is flowed by acid wash liquid pump 7 in reagent needle rinse bath 5, and reagent needle is in reagent needle rinse bath 5 In compressing 10 times repeatedly, to achieve the purpose that acid reagent needle 27.
4, removal waste fluid
When the air pressure in negative-pressure cup 14 is higher than -1.5kg/m2When, negative pressure pump 13 starts.Air is through 11 noise reduction of muffler Outflow, when the air pressure in negative-pressure cup 14 is less than -2.5kg/m2When, negative pressure pump 13 is closed.When waste liquid liquid level is higher than third liquid When 15 alarm liquid level of level sensor, waste discharge liquid pump 17 starts, and third solenoid valve 16 is opened, and starts removal waste fluid.When waste liquid is less than report When alert liquid level, third solenoid valve 16 is closed, and waste discharge liquid pump 17 stops.Reagent needle rinse bath 5 and specimen needle rinse bath 6 are after washing 0.2S opens third solenoid valve 16, starts to clear and washes waste water, and third solenoid valve 16 is closed after cleaning.Reagent needle rinse bath 5 0.2S opens third solenoid valve 16 after the completion of pickling with specimen needle rinse bath 6, starts to clear and washes pickling washing lotion waste water, has cleaned Third solenoid valve 16 is closed after finishing.
This flow path system the degree of automation is relatively high.Not only allow for stocking system, it is also contemplated that waste collection system, shape At closed-loop control.And due to the external pressure sensor of negative-pressure cup, it can prompt whether negative pressure pot liquid can meet experiment institute The number of injections needed.If negative pressure pot liquid is used up, this system can prompt operating personnel to carry out changing bottle action.Clean water Tank, acid wash liquid bottle and waste liquid bottle are equipped with liquid level sensor, once cleaning solution is used up or waste liquid bottle is full of, this system can be in time It provides corresponding prompt and quiescing personnel carries out any operation, have and only operating personnel add cleaning solution or fall again After falling the waste liquid in waste liquid bottle, this system can just operate again.
The light-induced chemiluminescent analyzer for using above-mentioned flow path system has higher the degree of automation, simultaneously because increasing Added real-time detection and automatic protection functions so that light-induced chemiluminescent analyzer is more intelligent, the safety of analyzer and Reliability higher can bring the better operating experience of operator.
Compared with prior art, the utility model has the advantage of flow path system according to the present utility model passes through setting Dispensing and rinse-system, sour cleaning system and waste discharge system, realize the multinomial work(such as storage, sample introduction, waste collection of specimen fluids Can, high degree of automation, and have monitoring and automatic protection functions in real time, improve the safety and reliability of system.According to The light-induced chemiluminescent analyzer of the utility model, as a result of above-mentioned flow path system, therefore, not only high degree of automation, And safety and reliability is high, can bring the better operating experience of operator.
Above description is merely a prefered embodiment of the utility model, but scope of protection of the utility model is not limited to This, any those skilled in the art can be easy to carry out and be altered or varied in technical scope disclosed by the utility model, and This be altered or varied should be covered within the scope of the utility model.Therefore, the scope of protection of the utility model is answered Subject to the scope of protection of the claims.
