Embodiment 1

[0030] see Figure 1 to Figure 33 , the enricher disclosed in the embodiment of the present invention includes:

[0031] An enrichment housing 101, which encloses an enrichment chamber 1013 for containing the suction liquid;

[0032] The suction connection part 102, the suction connection part 102 is used to connect the suction mechanism 20 and the enrichment chamber 1013, so that the enrichment chamber 1013 forms a negative pressure under the action of the vacuum mechanism; and

[0033] The barrier 103, the barrier 103 is arranged on the enrichment housing 101, when the enrichment cavity 1013 forms a negative pressure, the sample can form a suction liquid through the barrier 103 and enter the enrichment cavity 1013, and in the barrier 103 Stuck with retentate.

[0034] When using the enricher 10 of the present invention, the enrichment cavity 1013 is communicated with the suction mechanism 20 through the suction connection part 102, and the part of the enrichment housing 101...

Embodiment 2

[0052] see Figure 34 to Figure 39 , the enrichment system of the present invention includes: a suction mechanism 20 and an enricher 10 as in any one of the embodiments, the suction mechanism 20 is set to be connected to the suction connection part 102, and the suction mechanism 20 is set to enable the enrichment The enrichment cavity 1013 of the device 10 generates negative pressure.

[0053] When using this enrichment system, connect the suction connection part 102 and the suction mechanism 20, move the enricher 10 so that the barrier 103 in the enricher 10 is placed under the sample liquid surface, and operate the suction mechanism 20 to make the enrichment The cavity 1013 forms a negative pressure, and the sample passes through the barrier 103 under the negative pressure to form aspiration liquid, enters the enrichment cavity 1013 , and retains the retentate on the barrier 103 . Compared with the prior art, the enrichment system of the present invention can complete the e...

Embodiment 3

[0067] see Figures 40 to 43 , the sample preparation system disclosed in the embodiment of the present invention includes a sample transfer mechanism 40 and an enrichment system as in any one of the second embodiment, the sample transfer mechanism 40 is configured to transfer the retentate on the barrier 103 to the detection carrier 50 .

[0068] When using the sample preparation system in the embodiment of the present invention, the sample transfer mechanism 40 transfers the retentate on the enricher 10 enriched by the enrichment system to the detection carrier 50 to prepare a sample. Due to the adoption of the sample manufacturing system of the present invention, the samples after enrichment treatment by the enrichment system are used, and the cost is reduced because the number of times of sample transfer is reduced during the process. Since there are few intermediate links, the precision of sample preparation can be improved, and the detection rate of samples can be improv...

Abstract

The invention discloses an enrichment device, an enrichment system, a sample manufacturing system and a sample detection system. The enrichment device comprises an enrichment housing, wherein the enrichment housing defines an enrichment cavity for accommodating suction liquid; a suction connecting part which is used for communicating the suction mechanism with the enrichment cavity, so that the enrichment cavity forms negative pressure under the action of a vacuumizing mechanism; and a separation part which is arranged on the enrichment housing, and when negative pressure is formed in the enrichment cavity, a sample can pass through the separation part and form the suction liquid to enter the enrichment cavity, and retentate is retained on the separation part.

Description

technical field [0001] The invention relates to the technical field of medical detection, and more specifically, to an enricher, an enrichment system, a sample manufacturing system and a sample detection system. Background technique [0002] Medical testing is the detection of collected blood, body fluids, secretions, excretions and exfoliations through visual observation, microscopy, physical, chemical, instrumental or molecular biological methods. In order to improve the detection rate of the formed components in the sample, it is necessary to enrich the sample. [0003] At present, the enrichment methods mainly include centrifugal precipitation method and natural precipitation method. Among them, the centrifugal precipitation method is to remove the supernatant and take the sediment for detection after the sample is centrifuged; the natural precipitation method is to remove the supernatant and take the sediment for detection after the sample is left to stand for a certai...
