Description
Technical field
The utility model relates to vitro diagnostic techniques field, particularly a kind of reagent arm position debugging apparatus.
Background technology
In the vitro diagnostic techniques process of biomedical sector, the quantitative height that all can relate to various instrument carries out in-vitro diagnosis application of sample or reagent adding is debugged and locates.Existing instrument reagent arm, as shown in Figure 1, comprise reagent arm 101, frame support component 102 and reagent needles 103, the adjustment method of this instrument reagent arm 101, usual employing be use pipettor quantitative liquid (such as 100 microlitres) is injected reaction cup 104, and then according to the height of reaction cup 104 liquid level, the height on reaction cup 104 liquid level by reagent needles 103 on eye observation reagent arm 101 or specimen needle, the height of reagent needles 103 or specimen needle on reagent arm 101 is positioned, completes the height debugging of reagent arm 101.The instrument reagent arm 101 of the good height of debugging in use, the height and position debugged is dropped to by regulating reagent arm 101, determine that reagent or sample are injected the amount of reaction cup 104 by reagent needles 103 on reagent arm 101 or specimen needle, namely to be declined the height or the degree of depth fixed by debugging software regulation and control instrument reagent arm 101 processed.
The feature of this adjustment method is in whole debug process, are all the interpolations having been judged whether reagent by reagent needles 103 on visual inspection reagent arm 101 or the height difference between specimen needle and reaction cup 104 liquid level, its naked eyes judge that reagent arm 101 completes reagent interpolation and is divided into two kinds of situations:
The first situation, as shown in Figure 2, when having judged that reagent adds, as reagent 100 microlitre originally need be added, reagent needles 103 on reagent arm 101 or specimen needle point are positioned at below reaction cup 104 liquid level, now, reagent needles 103 is immersed in liquid level with next segment length, after reagent needles 103 or specimen needle spray last reagent, reagent arm 101 promotes reagent needles 103 or specimen needle, due to reagent needles 103 or specimen needle surface and the tension force of reagent, reagent can form drop-wise in reagent needles 103 or specimen needle surface, therefore, a part of reagent can be taken away when reagent needles 103 or specimen needle leave liquid level, the actual institute reagent volumes added in reaction cup 104 be less than original needed for addition, namely 100 microlitres are less than,
The second situation, as shown in Figure 3, when having judged that reagent adds, as reagent 100 microlitre originally need be added, reagent needles 103 on reagent arm 101 or specimen needle point are positioned at more than liquid level one segment distance, after reagent needles 103 or specimen needle spray last reagent, reagent arm 101 promotes reagent needles 103 or specimen needle, due to reagent because surface tension forms drop-wise in reagent needles 103 or specimen needle surface, last reagent not contact reaction cup 104 liquid level and to incorporate in reaction cup 104 in reagent, thus produce an extension phenomenon, namely last reagent will stay the phenomenon of reagent needles 103 or specimen needle end usually, therefore, a part of reagent can be taken away when causing reagent needles 103 or specimen needle to leave, the actual institute reagent volumes added in reaction cup 104 be less than original needed for addition, namely 100 microlitres are less than.
