Referring to fig. 1, fig. 1 is a schematic structural diagram of an embodiment of a fluid path apparatus 100 provided in the present application.
The fluid path apparatus 100 generally includes a first reaction cell 10, a flow cell 12, a sample pushing assembly 14, a first positive pressure fluid source 16, a first fluid conducting path 18, a second reaction cell 20, a second positive pressure fluid source 22, a third fluid conducting path 24, a first waste fluid tank 26, a second waste fluid tank 28, and a fluid drainage assembly 30.
The flow chamber 12 is connected with a first waste liquid tank 26 and a second waste liquid tank 28 through a first liquid guide path 18, so that the liquid in the flow chamber 12 is guided to the first waste liquid tank 26 or the second waste liquid tank 28 through the first liquid guide path 18; the sample pushing assembly 14 is used for injecting the liquid in the first reaction cell 10 into the flow chamber 12 to form a sheath liquid in the flow chamber 12 so as to perform counting detection; the first positive pressure liquid source 16 is connected to the flow chamber 12, and is used to introduce a cleaning liquid into the flow chamber 12 after the counting is completed, so as to clean the flow chamber 12 and the first liquid guide path 18. Wherein, the primary cleaning waste liquid formed after the first cleaning of the flow chamber 12 and the first liquid guide path 18 is collected in the first waste liquid tank 26; after the first cleaning of the flow chamber 12 and the first liquid guiding path 18, the secondary cleaning waste liquid formed by the second cleaning of the flow chamber 12 and the first liquid guiding path 18 is collected in the second waste liquid tank 28.

In this embodiment, the first liquid guiding path 18 includes a three-way valve 180 and a two-way valve 182, the two-way valve 182 communicates the common end of the flow chamber 12 and the three-way valve 180, the normally open end of the three-way valve 180 communicates with the first waste liquid tank 26, and the normally closed end of the three-way valve 180 communicates with the second waste liquid tank 28. The two-way valve 182 is a normally open two-way valve to isolate the flow chamber 12 from the first waste liquid tank 26 and the second waste liquid tank 28 when the flow chamber 12 is not in use, so as to prevent the waste liquid in the first waste liquid tank 26 and the second waste liquid tank 28 from evaporating and escaping to the flow chamber 12, thereby polluting the flow chamber 12 and the first liquid guide passage 18 partially communicated with the flow chamber 12.
During counting detection, the two-way valve 182 is turned on, so that the flow chamber 12 is communicated with the first waste liquid tank 26, and sheath liquid after counting detection is collected in the first waste liquid tank 26; after the count detection is completed, the first positive pressure liquid source 16 injects a cleaning liquid into the flow cell 12.
In other embodiments, the first liquid guiding passage 18 may further include a three-way pipe and two-way valves, which are not limited in this application.
The above-mentioned flow cell 12 and first liquid guiding path 18 for counting detection need to have high cleanliness and weak contamination resistance, and once the flow cell 12 and first liquid guiding path 18 are contaminated, the counting result will be affected, so after the counting detection is completed, it needs to be cleaned many times and in large quantity to ensure that there is no sample, no reagent and no air bubble, and thus a large amount of cleaning solution needs to be consumed.
During the first cleaning, the cleaning solution washes the flow chamber 12 and the first liquid guiding path 18 to wash away most of the sample liquid and the reagent liquid and the like stained in the flow chamber 12 and the first liquid guiding path 18, so as to form a primary cleaning waste liquid, wherein the primary cleaning waste liquid contains more sample content and reagent content; after the first cleaning, the sample content and the reagent content in the secondary cleaning waste liquid formed by the second cleaning flow chamber 12 and the first liquid guiding path 18 are greatly reduced, and then the flow chamber 12 and the first liquid guiding path 18 are thoroughly cleaned, and a large amount of secondary cleaning waste liquid is collected in the second waste liquid tank 28, so that the relatively clean secondary cleaning waste liquid can be used for cleaning waste liquid pipelines and the like, the utilization rate of the cleaning liquid is improved, and the cost of the cleaning liquid is relatively reduced.
Further, the liquid path device 100 further includes a second liquid guiding pipeline 19, the first reaction tank 10 communicates the liquid discharging assembly 30 and the second waste liquid tank 28 through the second liquid guiding pipeline 19, the sample residual liquid and the like in the first reaction tank 10 and the primary cleaning waste liquid for cleaning the first reaction tank 10 for the first time are discharged to the outside through the liquid discharging assembly 30 through the second liquid guiding pipeline 19, the secondary cleaning waste liquid for cleaning the first reaction tank 10 for the second time is collected in the second waste liquid tank 28, so that the liquid discharging assembly 30 is cleaned in the process of discharging the secondary cleaning waste liquid to the outside through the liquid discharging assembly 30.

Wherein, the primary cleaning waste liquid formed after the first cleaning of the second reaction tank 20 and the third liquid guide path 24 is collected in the first waste liquid tank 26; after the first cleaning of the reaction tank 20 and the third liquid guiding path 24, the secondary cleaning waste liquid formed by the second cleaning of the reaction tank 20 and the third liquid guiding path 24 is collected in the second waste liquid tank 28.

The two-way valve 242 is a normally open two-way valve to isolate the second reaction tank 20 from the first waste liquid tank 26 and the second waste liquid tank 28 when the second reaction tank 20 is not in use, so as to prevent the waste liquid in the first waste liquid tank 26 and the second waste liquid tank 28 from evaporating and escaping to the second reaction tank 20, and thus the second reaction tank 20 and a part of the third liquid guide path 24 communicated with the second reaction tank 20 are polluted.
In other embodiments, the second liquid guiding passage 24 may further include a three-way pipe and two-way valves, which are not limited in this application.
The second reaction tank 20 may be a reaction tank or a detection tank such as a resistance tank which requires high cleanliness and is weak in contamination resistance, and thus, it is necessary to clean it many times and consume a large amount of cleaning liquid. Therefore, the primary cleaning waste liquid is collected in the first waste liquid tank 26, and the secondary cleaning waste liquid is collected in the second waste liquid tank 28, so that the secondary cleaning waste liquid is reused for cleaning waste liquid pipelines and the like, the utilization rate of the cleaning liquid is improved, and the cost of the cleaning liquid is relatively reduced.
