Referring to fig. 1, fig. 1 is a schematic structural diagram of a first embodiment of a blood cell analyzer provided in the present application. As shown in fig. 1, the blood cell analyzer includes a first reaction cell 110, a second reaction cell 120, a reagent supply module 20, and a detection module 30.

Specifically, the first reaction cell 110 is used for storing a first original sample, and the second reaction cell 120 is used for storing a second original sample; the reagent supply module 20 is connected to the first reaction cell 110 and the second reaction cell 120, respectively, for adding a reagent to the first reaction cell 110 and the second reaction cell 120 to obtain a first sample to be tested and a second sample to be tested; the detection module 30 is connected to the first reaction tank 110 and the second reaction tank 120, respectively, and is configured to detect the first sample to be detected and the second sample to be detected in the same detection mode.

The first and second raw samples are blood samples to be tested obtained by the blood cell analyzer, and the reagent supply module 20 is configured to provide a detection reagent for the first and second reaction tanks 110 and 120, so that the raw samples react with the detection reagent for a preset time to obtain a sample to be tested that can be tested. It will be appreciated that depending on the detection requirements, different types of reagents may be used for the detection reagent, for example, when the blood cell analyzer is used to detect a white blood cell parameter in an original sample, the detection reagent may include a hemolyzing agent or the like for lysing red blood cells in the blood sample. The detection module 30 detects the first sample to be detected and the second sample to be detected in the same detection mode and the same detection item, for example, the detection module 30 detects the specific protein of the first sample to be detected and the second sample to be detected respectively, and at this time, the first detection period and the second detection period are partially overlapped.

The time when the blood cell analyzer detects the first original sample through the first reaction cell 110 is defined as a first detection period, and the time when the blood cell analyzer detects the second original sample through the second reaction cell 120 is defined as a second detection period. The first detection period may include the whole period of the blood cell analyzer obtaining the first original sample, processing the first original sample, distributing the first original sample to the first reaction tank 110, reacting the first original sample with the detection reagent in the first reaction tank 110, detecting the first sample to be detected by the detection module 30, and so on; the second detection cycle may include the whole cycle of the blood cell analyzer obtaining the second original sample, processing the second original sample, distributing the second original sample to the second reaction cell 120, reacting the second original sample with the detection reagent in the second reaction cell 120, detecting the second sample to be detected by the detection module 30, and so on.

In an alternative embodiment, the difference between the time when the reaction of the first original sample is completed and the time when the reaction of the second original sample is completed is defined as a first period, in which the detection module 30 detects the first sample to be detected after the reaction is completed, and washes the detection module 30 after the detection is completed, so that the detection module 30 can detect the second sample to be detected immediately after the reaction of the second original sample is completed, thereby accelerating the detection efficiency. In other embodiments, the period of time during which the detection module 30 detects the first sample to be detected may partially overlap with the first period of time, which is not specifically limited herein.

The first detection period and the second detection period of the present embodiment at least partially overlap, specifically, the overlapping portion of the first detection period and the second detection period is reflected in that when a part of modules of the blood cell analyzer perform the detection action of the first detection period, another part of modules of the blood cell analyzer perform the detection action of the second detection period, that is, the blood cell analyzer may perform the detection action of the first detection period and the detection action of the second detection period at a certain time or in a certain period.

The blood cell analyzer comprises a sampling module, wherein the sampling module is used for acquiring a first original sample and a second original sample from a sample tube of sample injection, specifically, the sampling module can acquire the first original sample and the second original sample from the sample tube of sample injection successively, and can also acquire the first original sample and the second original sample at one time. For example, the at least partial overlap of the first detection period and the second detection period may be embodied in: after the sampling module adds the first original sample to the first reaction cell 110, the reagent supply module 20 may deliver the detection reagent to the first reaction cell 110, and meanwhile, the reagent supply module 20 may also deliver the cleaning reagent to the sampling module and the second reaction cell 120 to clean the sampling module and the second reaction cell 120, so that the sampling module continues to obtain the second original sample and adds the second original sample to the second reaction cell 120; or, the reaction time of the first original sample in the first reaction tank 110 and the reaction time of the second original sample in the second reaction tank 120 have a preset time difference, so that after the detection module 30 detects the first sample to be detected, the second original sample in the second reaction tank 120 completely reacts with the detection reagent, and the detection module 30 detects the second sample to be detected.

In this embodiment of the present application, the first detection period and the second detection period at least partially overlap, so that the detection module 30 can continuously detect the first detection sample and the second detection sample, reduce the waiting time when preparing the second detection sample, improve the utilization rate of the detection module 30, and further improve the detection speed of the blood cell analyzer.

Optionally, the reagent supply module 20 is configured to supply a detection reagent and a washing reagent, and in response to the first raw sample of the first reaction cell 110 reacting with the detection reagent, the reagent supply module 20 is configured to supply the washing reagent to the second reaction cell 120, so that the washed second reaction cell 120 is configured to perform a reaction of the second raw sample with the detection reagent.

Specifically, the reagent supply module 20 is used to supply a detection reagent and a washing reagent. In an alternative embodiment, the reagent supply module 20 is configured to provide the detection reagent to the first reaction cell 110 so as to react the first raw sample with the detection reagent for a preset time; meanwhile, the reagent supply module 20 is configured to supply a cleaning reagent to the second reaction tank 120 to clean the second reaction tank 120, so as to reduce the possibility of cross contamination between samples, and enable the second reaction tank 120 to perform a reaction of a second original sample.

It can be appreciated that in the present embodiment, the first detection period is located in the sample reaction stage of the first reaction cell 110, and the second reaction cell 120 performs a cleaning action to open the second detection period of the second original sample, so that the first detection period and the second detection period are partially overlapped. Because the sample reaction time is longer, other parts of the blood cell analyzer are in an idle state in the sample reaction process, the blood cell analyzer can start a second detection period by using the sample reaction time of the first original sample, so that the time for the detection module 30 to wait for the sample to finish the reaction is reduced, and the detection speed of the blood cell analyzer is improved.

Optionally, the blood cell analyzer includes a sampling module (not shown) for dispensing the first raw sample into the first reaction cell 110, the reagent supply module 20 for adding the detection reagent into the first reaction cell 110 to react the first raw sample with the detection reagent for a preset time, and the reagent supply module 20 for adding the washing reagent into the second reaction cell 120 and washing the second reaction cell 120 to cause the sampling module to dispense the second raw sample into the washed second reaction cell 120.

Specifically, the sampling module distributes a preset number of first raw samples to the first reaction cell 110, and the reagent supply module 20 adds a preset number of detection reagents to the first reaction cell 110 to react the first raw samples with the detection reagents for a preset time to obtain a first sample to be tested. In the process of reacting the first raw sample with the detection reagent, the reagent supply module 20 is configured to add a cleaning reagent to the second reaction tank 120, so as to clean the last sample liquid remaining in the second reaction tank 120, so that the sampling module can continuously suck the second raw sample, and distribute the second raw sample to the second reaction tank 120 after cleaning.

Alternatively, the sampling module may simultaneously draw the first raw sample and the second raw sample at a time, the sampling module distributes a preset number of the first raw samples to the first reaction cell 110, and the reagent supply module 20 adds a preset number of detection reagents to the first reaction cell 110 to react the first raw samples with the detection reagents for a preset time to obtain the first sample to be tested. During the reaction of the first raw sample and the detection reagent, the reagent supply module 20 is configured to add a cleaning reagent to the second reaction tank 120 to clean the last sample liquid remaining in the second reaction tank 120, so that the sampling module can continue to distribute the second raw sample with a preset amount to the second reaction tank 120 after the cleaning is completed.

In this embodiment, the reagent supply module 20 washes the second reaction cell 120 to distribute the second raw sample to the washed second reaction cell 120, so that the first detection period and the second detection period partially overlap. Because the sample reaction time is longer, other parts of the blood cell analyzer are in an idle state in the sample reaction process, the blood cell analyzer can start a second detection period by using the sample reaction time of the first original sample, so that the time for the detection module 30 to wait for the sample to finish the reaction is reduced, and the detection speed of the blood cell analyzer is improved.
