Description

Technical Field

[0001] The invention relates to the technical field of tubular luminescence, and in particular to a tubular luminescence instrument. Background Art

[0002] The existing tube-type luminometer has the problems of cross contamination between reaction cups during the test, serious loss of sampling tubes, and a small number of workstations on the reagent tray and reaction tray in the tube-type luminometer.

[0003] The principle of the tube luminescence test is: the sample and the microsphere reagent (the microspheres are magnetic microspheres) react in the reaction cup, so that the reaction substances in the sample adhere to the microspheres, and then the microspheres are cleaned, and finally another reagent is added for chemiluminescence testing. The more reaction substances adhere to the magnetic microspheres, the brighter the light emitted.

[0004] The existing tubular luminescence instrument mainly uses the "magnet + steel needle" method to wash the reaction cup, that is, use a magnet to absorb the reaction material (for example, suck it to the edge of the reaction cup), and then use a steel needle to remove the liquid, or a disposable tip to remove the liquid. The reaction cup used in the tubular luminescence instrument is a conventional cup body (open at the top and closed at the bottom). This kind of cup requires a steel needle when filling it with liquid and washing the cup. The steel needle must be cleaned once it is used up. However, in actual operations, the flushing of the steel needle is incomplete and the steel needle will still carry contamination. In order to completely avoid this contamination, a disposable tip must be used. A complex experiment will cause considerable loss to the tip.

[0005] Secondly, the reaction tray and reagent tray in the tube-type luminometer are linear and can only move in a linear direction, so that the reaction tray and reagent tray occupy a larger space when working in the instrument. In instruments of the same specifications and models, more workstations cannot be designed for the reaction tray and reagent tray, resulting in an overall small number of workstations in existing tube-type luminometers. Summary of the invention

[0006] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a tubular luminometer to solve the problem that when the existing tubular luminometer performs a tubular luminescence test, the washing of the reaction cups easily causes cross contamination between the reaction cups.

When the reaction cup is washed, liquid can be drained at the bottom of the reaction cup. The drainage of the reaction cup does not require the use of a steel needle or a sampling tube, which completely avoids the use of a steel needle to remove liquid contamination and also avoids the need to consume a large number of tips to remove liquid during the experiment.

[0035] The reaction cup with filter membrane can remove the liquid from the bottom. When using the reaction cup with filter membrane used in this instrument for testing, non-magnetic microsphere reagents can be selected to greatly improve the efficiency of liquid removal in the reaction cup and the test efficiency.

[0036] When the tubular luminometer of the present invention washes the reaction cup, non-magnetic microspheres can be used as microsphere reagents. After the reaction substances are attached to the microspheres, the liquid in the reaction cup can be removed by the "negative pressure + filter membrane" method, and the previous "magnet + steel needle" method is no longer used, making the washing of the reaction cup more efficient.

[0092] A linear slide rail is arranged between the left and right slide seats 51 and the cross beam 11 of the frame 1. A first screw rod 511 is arranged on the cross beam 11 of the frame 1. The first screw rod 511 passes through the left and right slide seats 51 to drive the left and right slide seats 51 to move.

[0093] A pair of guide rods 522 and a second screw rod 521 are disposed on the left and right slides 51. The guide rods 522 and the second screw rod 521 pass through the front and rear slides 52. The second screw rod 521 rotates to drive the front and rear slides 52 to move forward and backward on the left and right slides 51.

[0094] A linear guide rail is arranged between the lifting seat 53 and the front and rear slide seats 52 . A third screw rod 531 is arranged on the front and rear slide seats 52 . The third screw rod 531 passes through the lifting seat 53 . The third screw rod 531 rotates to drive the lifting seat 53 to move up and down.

[0095] In this embodiment, a mounting frame 55 is provided on the left and right slides 51, and the guide rod 522 and the second screw rod 521 are connected to the mounting frame 55. The entire mounting frame 55 and the left and right slides 51 are an integrated structure. The function of the mounting frame 55 is to install the guide rod 522 and the second screw rod 521 on the left and right slides 51.

[0096] Specifically, as an optional implementation in this embodiment, Figure 6 As shown, an upper plate 512 is disposed on the left and right slide seats 51, and the upper plate 512 is located above the crossbeam 11, and a linear slide rail is disposed between the upper plate 512 and the crossbeam 11 of the frame 1;

[0100] During operation, the dilution cup is placed in the second cup hole 412 of the reaction disk 41, and the reaction cup 3 with the filter membrane 33 is placed in the first cup hole 411; the sampling arm 54 adds the type A reagent to the reaction cup 3 with the filter membrane 33, and the sample is diluted in the dilution cup of the reaction disk 41 and then added to the reaction cup 3 with the filter membrane 33 for mixing reaction;

[0101] After the reaction is completed, the reaction tray 41 moves to the washing station. At this time, the reaction cup 3 is located below the upper baffle 24. The push-pull electromagnet drives the drain pipe 21 to move upward, so that the drain pipe 21 is sealed with the bottom of the reaction cup 3. The negative pressure pump works to remove the reaction liquid of the reaction cup 3. The entire removal process does not require the use of a steel needle or a sampling tube, which completely avoids pollution and sampling tube loss. After removal, there will be microspheres in the reaction cup 3, and the microspheres will carry reactive substances. The cleaning liquid is injected into the reaction cup 3 through the liquid injection mechanism, and the cleaning liquid is sucked away by the negative pressure pump. Repeatedly, until the microspheres are cleaned, the next step can be entered: add the B-type reagent to the reaction cup 3 with the filter membrane 33 for mixing reaction. After the reaction is completed, the next step of the luminescence test can be entered. The luminescence test is not described in detail in this embodiment.

[0102] The Class A reagent bottles 61 and Class A sampling tubes 62 on the Class A reagent tray 42 are "dedicated bottles for dedicated purposes" to avoid cross contamination. The sampling arm 54 on the Class B reagent tray 42 can move to the perforation 561 and the slot 562 of the clamping plate 56 after using up the Class B sampling tube 63, and the Class B sampling tube 63 can be detached from the sampling arm 54 through the clamping plate 56, making it easier for the sampling arm 54 to connect a new Class B sampling tube 63.

[0103] The advantage of the tube-type luminometer of the present invention is that it adopts a reaction cup 3 with a filter membrane 33 of a new structure, and the bottom drainage is adopted for washing the reaction cup 3. The whole washing process does not require the use of a steel needle and a sampling tube, thereby avoiding cross contamination and sampling tube loss during the test.

[0104] The circular structures of the reagent disk 42 and the reaction disk 41 can be designed with more cup placement holes, so that more reagent bottles can be placed, and the space utilization is more reasonable.

[0105] The sampling tube in the sampling mechanism can be easily detached through the clamping plate 56, so that the sampling mechanism can perform sampling work quickly and efficiently.

[0106] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description.
