Description
Technical Field
The invention relates to a structure of a biochemical analyzer, in particular to an independent reaction cup fixing structure of the biochemical analyzer.
Background
The biochemical analyzer performs qualitative and quantitative analysis according to the absorption spectrum of a substance. When the biochemical analyzer works, a stable light beam irradiates a detected liquid sample arranged in the sample cell, and the composition and the concentration of the sample in the sample cell are determined according to the absorption spectrum of the sample. Is a common instrument used in hospitals and research departments. Most of sample cells of the full-automatic biochemical analyzer in the market at present are cuboid cups made of quartz or optical-grade hard plastic, and are commonly called reaction cups. The reaction cup is provided with four side surfaces and a bottom surface, wherein a pair of opposite side surfaces are light-transmitting surfaces; the reaction cup has a plurality of combined arc-shaped connected bodies and also has a single independent type. The reaction cup is generally uniformly arranged on a disc-shaped structure in a plurality of circular arcs, light beams penetrate through a detection window, the axis of the disc is perpendicular to the light transmission surface of the reaction cup, and the disc-shaped structure rotates around the axis when working and is often called as a reaction disc. The reaction disc makes circular motion in the measuring process, when the reaction disc is static, the instrument adds liquid samples and reagents into the reaction cup or uniformly mixes the samples and the reagents, when the reaction disc makes circular motion, the absorbance detection can be carried out through the reaction cup with the detection window irradiated by the light beam, after a certain monitoring time, the reaction and the detection in the reaction cup are finished, and the biochemical instrument cleaning system can clean and drain the reaction cup and then enter the next round of reaction detection.
A high-end biochemical analyzer is required to be an instrument with high detection speed, high detection precision, stable detection result and low individual difference. These all impose different requirements on the reaction cup. In order to achieve high detection speed, the more reaction cups can be arranged on the reaction disc with the same diameter, the better the effect is; in order to achieve high detection precision, a high-quality reaction cup is required to be pursued, wherein the reaction cup comprises a high light transmittance, a high-quality light-transmitting surface and high verticality of the light-transmitting surface and a light beam; in order to achieve stable detection results, the reaction cup is required not to shake when the reaction disc rotates in the detection monitoring process; in order to achieve low individual variability, it is desirable to achieve a high degree of accuracy in the position of the reaction cup mounted on the reaction tray.
The biochemical analyzer detection process is accompanied by the adding and stirring actions of liquid samples and reagents, and the reaction cup cleaning action after the reaction is finished, so that the detection abnormity can be caused by the pollution of the outer wall of the reaction cup due to the overflow of liquid possibly caused by the abnormal structure of the liquid path of the analyzer. This may result in the possibility that the user may remove the cup for inspection or cleaning.
At present, a medium-sized and small-sized full-automatic biochemical analyzer in the market adopts a conjoined reaction cup so as to achieve the purposes of reducing the space and the cost of the instrument. The integrated reaction cup is generally injection molded from optical grade hard plastic, or the freestanding reaction cup is mounted on a plastic injection molded cup holder. The first problem with these two approaches is that the cup cannot be replaced separately, increasing the cost of the consumable; secondly, the domestic injection molding level often can not reach better surface quality and form and position tolerance requirements, the batch difference is large, and the problem of further deformation caused by aging is solved. These problems cause much trouble to manufacturers and users.
The fixed knot that uses full-automatic biochemical analysis appearance of stand alone type reaction cup generally adopts at present constructs is fixed at the lateral wall of reaction cup non-light-transmitting face with the slice shell fragment, does not have any location relation between slice shell fragment and the reaction dish, and the slice shell fragment drops easily after the reaction cup takes out to influence the dismouting operating efficiency of reaction cup. Some manufacturers improve the structure, and a common mode is to make a vertical curved surface at the upper end of a sheet-shaped elastic sheet, and fix the sheet-shaped elastic sheet on the side wall of a reaction cup mounting groove (hereinafter referred to as a cup groove) by using a metal sheet along the circumferential direction of a reaction disk; the other mode is that two small grooves are processed on the side wall of the cup groove, two side surfaces of the upper end of the sheet-shaped elastic sheet are processed into arc-shaped bulges, when the sheet-shaped elastic sheet is pressed down, the arc-shaped bulges on the two side surfaces of the upper end of the sheet-shaped elastic sheet are fixed on the small grooves on the side wall of the cup groove, and the sheet-shaped elastic sheet is deformed to generate elasticity to be fixed in the circumferential direction.
The above conventional fixing method of the sheet-shaped elastic piece has the following problems:
1. the slice shell fragment is arranged in the cup groove side, arranges the direction for along reaction disk circumferencial direction, and slice shell fragment occupation space is too big like this, causes the reaction cup number that same diameter reaction disk can arrange to reduce, detects speed and reduces. In order to achieve the same detection speed, the diameter of the reaction disc needs to be increased, so that the weight of the reaction disc is increased, the size and the weight are increased, higher requirements are put forward on a control system, the cost of the reaction disc is increased, the cost of the control system is increased, the long-term working stability of the reaction disc is reduced, and the defect that the space of an instrument is increased is overcome.
2. The sheet-shaped elastic sheet is fixed on the side wall of the cup groove or two small grooves are processed on the side wall of the cup groove to fix the sheet-shaped elastic sheet along the circumferential direction of the reaction disk, so that the processing difficulty is inevitably increased, and the processing cost is increased.
3. The reaction cup is fixed to the slice shell fragment from the side, can guarantee the position degree of reaction cup in non-light-transmitting face direction, but the light-transmitting face direction can't exert the stationary force, like this, the straightness that hangs down of reaction cup light-transmitting face in the light beam direction can't avoid receiving the influence, has reduced instrument test accuracy.
Therefore, a new fixing method of the independent reaction cup is needed, which can realize compact and dense arrangement of the reaction cup, reduce the space, and overcome the disadvantages of the conjoined reaction cup.
