Description
Technical field
The present invention relates to a kind of Biochemical Analyzer, what be specifically related to is the Biochemical Analyzer of a kind of Biochemical Analyzer reagent disc and formation thereof and the method for position, orienting response chamber.
Background technology
Biochemical Analyzer is a kind of testing tool of medical in-vitro diagnosis direction, and because it has, measuring speed is fast, accuracy is high, consumption amount of reagent is little, thus obtains use widely at situation of all-level hospitals, epidemic prevention station, family planning services station.
The reagent disc supporting with Biochemical Analyzer is the carrier carrying biochemical reaction, and it is formed primarily of seat 5 of trying to get to the heart of a matter, as shown in Figure 1, 2.Each reagent disc all has several reaction chambers 6, and biochemical reaction then completes in each reaction chamber of reagent disc.Every platform instrument only has a reaction test position, and reagent disc turns to test position and completes test under the drive of analyser rotational motion mechanism.
As shown in Figure 3, the locator meams that the reagent disc of conventional biochemical analyser turns to test position is: have light fully reflecting surface 7 in reagent disc lateral layout, infrared emission end sends infrared ray, when rotational motion mechanism drives reagent disc to forward respective reaction chamber test position to, side fully reflecting surface also turns to infrared emission end.Now, the infrared ray that infrared emission end is launched reflexes to infrared receiver end by the fully reflecting surface of test panel side, and when hot outer receiving end receives infrared ray, reaction chamber arrives the test position of reagent disc, completes test.The edge of the width of the fully reflecting surface of reagent disc side as the detection of test panel reference position, then can detect reference position when this reflecting surface being detected.The corresponding unique fully reflecting surface of each reaction chamber, one of them fully reflecting surface width is 2 times of zero-bit starting points as reagent disc of all the other fully reflecting surface width.
But, the mode of above-mentioned orienting response chamber reference position causes structure comparatively too fat to move owing to designing unreasonable, the setting in light reflection face occupies the space of reagent disc, causes on reagent disc and cannot increase more multiple reaction cavity when same outer diameter, thus is difficult to improve the efficiency measured; Meanwhile, rely on infrared light receiving/transmitting device to test the input that also adds additional equipment cost.
Summary of the invention
The object of the present invention is to provide the Biochemical Analyzer of a kind of Biochemical Analyzer reagent disc and formation thereof and the method for position, orienting response chamber, mainly solve existing Biochemical Analyzer and there is the problem that measurement efficiency is low, equipment investment cost is high.
To achieve these goals, the technical solution used in the present invention is as follows:
Biochemical Analyzer reagent disc, comprise disk cover, water tumbler, try to get to the heart of a matter seat and reaction chamber, described disk cover is connected with seat of trying to get to the heart of a matter, described water tumbler is built in a center section of trying to get to the heart of a matter, described reaction chamber to be arranged in seat of trying to get to the heart of a matter and to radially distribute, also comprise and be arranged on dish upper part of the cover dish light blocking ring, in this dish light blocking ring, be provided with the through hole corresponding with reaction chamber.
Further, described Pan Dangguangquan and disk cover removably connect.
Based on said structure, the invention provides the Biochemical Analyzer be made up of this reagent disc, comprise the analyser main body with rotational motion mechanism, also comprise mentioned reagent dish, and be all arranged on the light source being used as test light in analyser main body and the luminous energy receiver as reaction test position; The seat of trying to get to the heart of a matter of described reagent disc is fixed on rotational motion mechanism, and described light source is positioned at above the dish frequency modulated light circle of reagent disc, and described luminous energy receiver is positioned at below seat of trying to get to the heart of a matter.
Further, present invention also offers the method for this position, Biochemical Analyzer orienting response chamber, comprise the following steps:
(1) light source controlled above reagent disc sends light, and is received by the luminous energy receiver below reagent disc, draws light energy value;
(2) rotational motion mechanism is utilized to drive reagent disc to rotate;
(3) when reagent disc rotates, according to the rotation direction of reagent disc, and the light energy value that the numerical value obtained when turning to test position according to reaction chamber and overlap with dish frequency modulated light ring through hole is non-vanishing, and reaction chamber to turn to the numerical value obtained when not overlapping with through hole be the light energy value of zero, determine the reference position of each reaction chamber, complete the location to reaction chamber position.
Compared with prior art, the present invention has following beneficial effect:
(1) structure of the present invention is ingenious, reasonable in design, it is while removing the light reflection face of reagent disc side, setting dish frequency modulated light circle on disk cover, the shielding to light can be realized, and rely on the through hole on it to be communicated with reaction chamber, this kind of reagent disc is applied to after in Biochemical Analyzer, when rotational motion mechanism drives reagent disc to rotate, test position can the light energy value that obtained by reagent disc of read test light always, when reaction chamber turns to test position, the energy value of light is a larger value, when rotational motion mechanism drives reagent disc to turn to the position of conductively-closed, the energy value of light is zero, thus, the position of each reaction chamber just can be detected by the change of light energy value, and judge its initial position by the height of light energy value.
(2) the present invention is on the basis that Rational structure designs, by changing the mode of position, orienting response chamber, without the need to again on reagent disc the side of each reaction chamber light reflection face is all set, and the direct benefit so designed is when being exactly identical reagent disc volume, the position that light reflection face is removed can increase more reaction chamber, thus increase the capacity of analyser measurement, and improve the efficiency measured.
(3) the present invention is after the mode changing position, orienting response chamber, unnecessary infrared light receiving/transmitting device can be removed equally, the straight line of light source is only relied on to launch and judge that the reception condition of luminous energy measuring device just can determine the position in fact of each reaction chamber, thus this also simplifies the structure of Biochemical Analyzer well, reduces the cost of equipment.
(4) cost performance of the present invention is high, easy to use, has application prospect widely.
