Utility model content
Technical problem to be solved in the utility model is, provides that a kind of structure is simple, volume compact, and the negative pressure liquid-adding device of cleaning fluid liquid storing barrel placement location automatic clinical chemistry analyzer more freely.
For solving the problems of the technologies described above, the negative pressure liquid-adding device of the automatic clinical chemistry analyzer that the utility model provides, comprise cleaning fluid liquid storing barrel, two position two-way valve, two position three-way valve and deionized water liquid-supplying system, be communicated with the filling opening on cleaning station after the first interface of two position two-way valve is communicated with the first interface of two position three-way valve, second interface of two position two-way valve is communicated with cleaning fluid liquid storing barrel, and the second interface of two position three-way valve is communicated with deionized water liquid-supplying system; It also comprises negative pressure device, and the 3rd interface of described two position three-way valve is communicated with negative pressure device.
Described negative pressure device is the pump assembly carried in automatic clinical chemistry analyzer.
Described cleaning fluid liquid storing barrel is positioned at low level place, and stretches into the cleaning fluid liquid level in cleaning fluid liquid storing barrel with the pipe ends of the second orifice of two position two-way valve, and pipe ends and cleaning fluid form enclosure space.
The quantity of described cleaning fluid liquid storing barrel is two, and the quantity of corresponding two position two-way valve and two position three-way valve is two, and the pipeline being communicated to the filling opening on cleaning station is two.
After adopting above structure, the utility model compared with prior art, has following advantage:
1) because one of them interface of two position three-way valve is communicated with negative pressure device, like this, under the effect of negative pressure device, cleaning fluid in cleaning fluid liquid storing barrel is drawn onto in pipeline, mix the conveying of backward cleaning station again together with deionized water according to a certain percentage, therefore, the position of cleaning fluid liquid storing barrel can arbitrarily be placed, without the need to relying on deadweight to carry out feed flow, thus make the structure of liquid-adding device compacter;
2) what negative pressure device adopted is original pump assembly in automatic clinical chemistry analyzer, therefore, without the need to increasing new parts in instrument, simplifies structure further;
3) cleaning fluid liquid storing barrel can be placed on low level place, thus makes cleaning fluid liquid storing barrel arbitrarily can be placed on the optional position of instrument internal, more freely.
