Abstract
The invention discloses a cuvette flushing system for a full automatic biochemical analyzer. The cuvette flushing system comprises a cleaning needle assembly, a liquid absorption block, a normally closed solenoid valve, a normally open solenoid valve, a constant pressure water pump and a water tank, wherein the cleaning needle assembly is connected with the liquid absorption block; the liquid absorption block is connected with the constant pressure water pump through the normally closed solenoid valve; a water outlet end of the constant pressure water pump is connected with the water tank; and the water tank is provided with a water outlet pipe which is connected to a water inlet end of the constant pressure water pump through the normally open solenoid valve. The cuvette flushing system is simple in structure, low in manufacturing cost and convenient for maintenance.
Description
Technical field
The present invention relates to a kind of cuvette rinse-system, particularly a kind of cuvette rinse-system of automatic clinical chemistry analyzer device.
Background technology
What automatic clinical chemistry analyzer adopted is permanent quartz cuvette or reusable plastic cup, and cuvette uses repeatedly, has therefore adopted the purging method of eight steps cleaning.Rinse-system is mainly by negative pressure device, water filling device, cleaning needle assembly.Its cleaning process comprises and blots reactant liquor, injects alkaline cleaner, blots alkaline cleaner, injects acidic cleaner, blots acidic cleaner, injects steps such as deionized water (repeatedly), dry reaction cup.
The negative pressure device of automatic clinical chemistry analyzer comprises now: parts such as air pump, gas tank, imbibition body, vacuum table, unwatering pump, negative pressure solenoid valve, aspirating needle are formed, its structure more complicated, and the manufacturing cost height, work is unstable.
The rinse-system of automatic clinical chemistry analyzer is when work, be several times the rinse water in the cuvette and cleaning fluid to be blotted by negative pressure device, this requirement will have enough negative pressure, and the sealing property of total system will be got well, because the waste liquid that sucks out contains potential of hydrogen than high, the corrosion resistant of air pump, solenoid valve in the device is required all than higher.Negative pressure will descend gradually after work a period of time, makes the test performance that cuvette cleans does not totally influence instrument.
Summary of the invention
Technical matters to be solved by this invention provides a kind of cuvette rinse-system of automatic clinical chemistry analyzer device, and it is simple in structure, and is cheap for manufacturing cost, easy to maintenance.
For solveing the technical problem, the invention provides a kind of cuvette rinse-system of automatic clinical chemistry analyzer device, it is characterized in that, it comprises cleaning needle assembly, liquid-absorbing block, normally closed solenoid valve, normally open solenoid valve, constant voltage water pump, water tank, the cleaning needle group is connected with liquid-absorbing block, liquid-absorbing block is connected with the constant voltage water pump through normally closed solenoid valve, and the water side of constant voltage water pump is connected with water tank, and water tank has a rising pipe to be connected to the water inlet end of constant voltage water pump through normally open solenoid valve.
Positive progressive effect of the present invention is: one, the present invention is simple in structure, with low cost; Two, because what use is the constant voltage water pump among the present invention, and the constant voltage water pump is continuous duty, and pressure is constant when making imbibition, can blot the waste liquid in the cuvette only guaranteeing at every turn, guaranteed the reliability of instrument testing result.Three, noise of the present invention is little, easy to maintenance.
Description of drawings
Fig. 1 is the structural representation of one embodiment of the invention.
Embodiment
Lift a preferred embodiment below, and come the clearer the present invention that intactly illustrates by reference to the accompanying drawings.
As shown in Figure 1, the cuvette rinse-system of automatic clinical chemistry analyzer device of the present invention comprises cleaning needle assembly 1, liquid-absorbing block 2, normally closed solenoid valve 3, normally open solenoid valve 4, constant voltage water pump 5, water tank 6, cleaning needle assembly 1 is connected with liquid-absorbing block 2, the suction that produces every cleaning needle is equated, liquid-absorbing block 2 is connected with constant voltage water pump 5 through normally closed solenoid valve 3, the water side of constant voltage water pump 5 is connected with water tank 6, water tank 6 has a rising pipe to be connected to the water inlet end of constant voltage water pump 5 through normally open solenoid valve 4, for prolonging life-span and the stability of constant voltage water pump, the constant voltage water pump is designed to continuous duty, normally closed solenoid valve is opened when imbibition, waste liquid in the cuvette is drawn onto in the water tank and flows out through overflow vent after the dilution, normally closed closed electromagnetic valve when not imbibition, simultaneously normally open solenoid valve is opened, and has avoided the no-load running of constant voltage water pump and damages.
Described constant voltage water pump is owing to be continuous duty, and pressure is constant when making imbibition, can the waste liquid in the cuvette be blotted only guaranteeing at every turn.The present invention is applicable to the full automatic biochemical apparatus of various use circulation cuvettes, and is more reliable, simple in structure, cheap for manufacturing cost, easy to maintenance than existing cuvette rinse-system.
Though more than described the specific embodiment of the present invention, it will be understood by those of skill in the art that these only illustrate, under the prerequisite that does not deviate from principle of the present invention and essence, can make numerous variations or modification to these embodiments.Therefore, protection scope of the present invention is limited by appended claims.
