Description

Technical Field

[0001] The present invention relates to the field of in vitro diagnostic equipment, and in particular to a urine analyzer. Background Art

[0002] A urine analyzer provided by the related art performs dry chemical determination on urine samples in the following manner: after the sample needle distributes the urine sample onto the test strip, the test strip conveying mechanism conveys the test strip to the result acquisition position for determination in an intermittent driving manner. The test strip conveying mechanism conveys the test strip from the sample adding position to the result acquisition position, which requires multiple start-stop periods. During each start-stop period, the test strip conveying mechanism performs a start-stop action to convey the test strip from one working position to the next working position, and during each start-stop period, the test strip scheduling mechanism schedules a test strip to the test strip conveying mechanism. In the related art, the duration of multiple start-stop periods is fixed and the same.

[0003] The operation mode of the above-mentioned test strip conveying mechanism has the following shortcomings in specific applications: (1) It is difficult to balance the improvement of detection speed and ensure that the urine sample has sufficient reaction time on the test strip. If you want to balance the reaction time and detection speed, if you keep the original test strip conveying mechanism operation cycle scheduling scheme, you can only modify the structure of the test strip conveying mechanism, such as adding or reducing working positions. However, this will lead to the problem that different test strips and different urine analyzers are difficult to share the same test strip conveying mechanism, thereby bringing higher costs to the urine analyzer. On the contrary, if the structure of the test strip conveying mechanism is forcibly guaranteed to be consistent, it is difficult to ensure the reaction time or to improve the detection speed, which is not conducive to improving the performance of the urine analyzer. (2) If the above-mentioned dry chemical determination function module and the tangible component determination function module are integrated into a urine analyzer, there will be at least two modes in the urine analyzer, namely, a single dry chemical determination mode and a comprehensive determination mode (dry chemical + tangible). In order to ensure that the corresponding dry chemical performance of these two different modes is consistent, the above-mentioned test strip conveying mechanism operation cycle configuration scheme will cause the detection speed of the single dry chemical determination mode to be greatly reduced.

The dry chemical determination component 300 is used to perform dry chemical determination on the urine sample through the test strip 20, and the formed component determination component 100 is used to perform formed component determination on the urine sample; the sample distribution component 400 is used to absorb the urine sample from the sample container, and distribute at least part of the absorbed urine sample to the test strip 20 and / or the formed component determination component 100 located on the dry chemical determination component 300. The controller 200 is at least used to control the operation of the sample distribution component 400 to control the sample distribution component 400 to perform sample suction and sample discharge operations. In this embodiment, the formed component determination component 100 and the dry chemical determination component 300 are integrated in the same analyzer, so that different determination items of the same urine sample do not need to be transmitted, which is conducive to improving the determination efficiency of urine samples with multiple determination items, and is conducive to avoiding the occurrence of errors in the correspondence between the determination items and the urine samples.

[0085] The determination of formed elements in urine samples refers to the determination of formed elements such as cytological components (such as red blood cells, white blood cells, epithelial cells, etc.), casts and crystals in urine samples. The determination of formed elements in urine samples can make up for missed diagnoses caused by insufficient physical and chemical tests of urine, and can understand the changes in various parts of the urinary system, which is of great significance in assisting the localization diagnosis and prognosis of urinary system diseases.

[0086] The dry chemical determination of urine samples refers to the determination of chemical components in urine samples, that is, the determination of corresponding chemical components in urine samples by using dry chemical determination assembly 300. Dry chemical determination technology is relative to wet chemical determination technology, which refers to a method of adding urine samples directly to dry test strips 20 specially produced for different projects, using the water in the urine sample to be tested as a solvent to induce a specific chemical reaction, thereby performing chemical analysis.

[0087] As an embodiment, the chemical components in the urine sample can cause the color of the color-developing area on the test strip 20 to change, and the color depth is proportional to the concentration of the corresponding substance in the urine sample. The dry chemical determination method of urine samples can assist in the diagnosis and efficacy observation of diseases such as urinary system diseases, hepatobiliary diseases, and diabetes, monitor the safe use of drugs, and evaluate health status.

[0088] As an embodiment, the dry chemical determination component 300 includes a test strip storage mechanism 310, a test strip scheduling mechanism 320, a test strip transmission mechanism 330 and a result acquisition component 340. The test strip storage mechanism 310 is used to place the test strip 20, the test strip scheduling mechanism 320 is used to schedule the test strip 20 from the test strip storage mechanism 310 to the test strip transmission mechanism 330, and the test strip transmission mechanism 330 is used to sequentially transmit the test strip 20 to at least three working positions in an intermittent driving manner. The at least three working positions include a sample loading position, at least one reaction position and a result acquisition position. The sample loading position is used to carry the test strip 20 for loading, the reaction position is used to cache the test strip 20 after loading for reaction, and the result acquisition component 340 is used to obtain the reaction result information of the urine sample on the test strip 20 located at the result acquisition position. The sample distribution component 400 is used to absorb the urine sample from the sample container and distribute at least part of the absorbed urine sample to the test strip 20 located on the test strip transmission mechanism 330 and at the sample loading position and / or the formed component determination component 100.

[0089] As an embodiment, the controller 200 is configured with a first working mode and a second working mode. The first working mode is used to perform dry chemical measurement items on the urine sample alone, and the second working mode is used to perform dry chemical measurement items and formed component measurement items on the urine sample.

[0090] As an embodiment, in the first working mode, the controller 200 is configured to: control the sample dispensing component 400 to absorb the urine sample from the sample container in the first sample distribution cycle, and distribute at least part of the absorbed urine sample to the test strip 20 located on the test strip transmission mechanism 330 and at the sample loading position; control the test strip transmission mechanism 330 to operate in a first intermittent driving mode to transport the test strip 20, control the result acquisition component 340 to acquire the reaction result information of the urine sample on the test strip 20 transmitted by the test strip transmission mechanism 330 to the result acquisition position, and obtain the dry chemical determination result of the urine sample according to the feedback information of the result acquisition component 340. In the first working mode, the urine sample absorbed by the sample dispensing component 400 is only distributed to the test strip 20 located on the test strip transmission mechanism 330 and at the sample loading position, and is not distributed to the formed component determination component 100.

[0091] As an embodiment, in the second working mode, the controller 200 is configured to: control the sample distribution component 400 to absorb the urine sample from the sample container within the second sample distribution cycle, and distribute at least part of the absorbed urine sample to the test strip 20 located on the test strip transmission mechanism 330 and at the sample loading position and the formed component determination component 100 respectively; and control the formed component determination component 100 to perform formed component determination on the urine sample; control the test strip transmission mechanism 330 to operate in a second intermittent driving mode to transport the test strip 20; control the result acquisition component 340 to acquire the reaction result information of the urine sample on the test strip 20 transmitted by the test strip transmission mechanism 330 to the result acquisition position, and obtain the dry chemical determination result of the urine sample according to the feedback information of the result acquisition component 340. In the second working mode, the urine sample absorbed by the sample distribution component 400 needs to be distributed to the test strip 20 located on the test strip transmission mechanism 330 and at the sample loading position and the formed component determination component 100 respectively. The distribution order is not prioritized, that is, it can be distributed to the test strip 20 first and then to the formed component determination component 100, or it can be distributed to the formed component determination component 100 first and then to the test strip 20.

[0092] As an embodiment, at least one of the following durations in the first working mode and the second working mode is different: the duration of the first sample splitting cycle and the duration of the second sample splitting cycle, the interval duration of at least part of the start and stop actions of the test strip transmission mechanism 330 in the first intermittent driving mode and the second intermittent driving mode, and the interval duration of the test strip scheduling mechanism 320 scheduling the test strip 20 to the test strip transmission mechanism 330. In this embodiment, by setting the sample splitting cycle of the sample distribution component 400 and / or the scheduling and transmission cycle of the test strip 20 in the first working mode and the second working mode to be different, it is beneficial to improve the detection speed of the urine analyzer 10 for urine samples, especially the detection speed of dry chemical determination items, while ensuring that the sample distribution action and the result acquisition action will not be interfered by the transmission action of the test strip 20.

[0093] As an implementation manner, the controller 200 is further configured with a third working mode, and the third working mode is used to perform the measurement of formed component measurement items separately on the urine sample.

[0094] As an embodiment, the first intermittent driving mode includes: the test strip transmission mechanism 330 cyclically operates in a first intermittent operation cycle, the first intermittent operation cycle includes at least three first start-stop periods, and each first start-stop period includes a start-stop action of the test strip transmission mechanism 330.

[0095] As an embodiment, the starting time of each first start-stop period is the time when the test strip transmission mechanism 330 starts to start transmitting the test strip 20 in the first start-stop period, and the end time of each first start-stop period is the time when the test strip transmission mechanism 330 starts to start transmitting the test strip 20 in the next first start-stop period.

[0096] Alternatively, as another embodiment, the starting time of each first start-stop period is the time when the test strip transmission mechanism 330 starts to drive the test strip 20 from one work station to another work station during the first start-stop period, and the end time of each first start-stop period is the time when the test strip 20 is transferred from the above-mentioned another work station to another work station. Here, one work station, another work station, and another work station are mainly used to specify three consecutive and adjacent work stations.

[0097] As an embodiment, the second intermittent driving mode includes: the test strip transmission mechanism 330 cyclically operates in a second intermittent operation cycle, the second intermittent operation cycle includes at least three second start-stop periods, and each second start-stop period includes a start-stop action of the test strip transmission mechanism 330.

[0098] As an embodiment, the starting time of each second start-stop period is the time when the test strip transmission mechanism 330 starts to start transmitting the test strip 20 in the second start-stop period, and the end time of each second start-stop period is the time when the test strip transmission mechanism 330 starts to start transmitting the test strip 20 in the next second start-stop period.

[0099] Alternatively, as another embodiment, the starting time of each second start-stop period is the time when the test strip transmission mechanism 330 starts to drive the test strip 20 from one work station to another work station during the second start-stop period, and the end time of each second start-stop period is the time when the test strip 20 is transferred from the above-mentioned another work station to another work station. Here, one work station, another work station, and another work station are mainly used to specify three consecutive and adjacent work stations.

[0100] As an implementation mode, the first intermittent driving mode and the second intermittent driving mode have different interval durations of at least some start and stop actions, including: the duration of at least one first start and stop period is different from the duration of at least one second start and stop period, which is conducive to matching the different sampling cycles and detection speed requirements in the first working mode and the second working mode.

[0101] As an embodiment, the controller 200 is further configured to obtain the number of first start-stop periods included in the first intermittent operation cycle and the duration of each first start-stop period according to the first preset detection speed of the urine analyzer 10 in the first working mode, the preset reaction time of the urine sample on the test strip 20, and the number of reaction positions between the sample loading position and the result acquisition position on the test strip transmission mechanism 330. The controller 200 is further configured to obtain the number of second start-stop periods included in the second intermittent operation cycle and the duration of each second start-stop period according to the second preset detection speed of the urine analyzer 10 in the second working mode, the preset reaction time of the urine sample on the test strip 20, and the number of reaction positions between the sample loading position and the result acquisition position on the test strip transmission mechanism 330. In this embodiment, the duration of each start and stop period in the intermittent operation cycle can be set according to the preset detection speed, the preset reaction time of the urine sample on the test strip 20, and the number of reaction positions between the sample loading position and the result acquisition position on the test strip transmission mechanism 330, so as to take into account the detection speed of the urine analyzer 10 and the reaction time of the urine sample on the test strip 20, and to ensure that the sample distribution action and the result acquisition action will not be interfered by the transmission action of the test strip 20.

[0102] As an implementation manner, the duration of at least one second start-stop period in the second intermittent operation cycle is longer than the duration of any first start-stop period in the first intermittent operation cycle.

[0103] As an embodiment, at least two first start and stop periods are of unequal duration, which helps to take into account the detection speed of the urine analyzer 10 in the first working mode and the reaction time of the urine sample on the test strip 20, and helps to ensure that the sample distribution action and the result acquisition action will not be interfered with by the transmission action of the test strip 20.

[0104] As an embodiment, at least two second start and stop periods are of unequal duration, which helps to take into account the detection speed of the urine analyzer 10 in the second working mode and the reaction time of the urine sample on the test strip 20, and helps to ensure that the sample distribution action and the result acquisition action will not be interfered with by the transmission action of the test strip 20.

[0105] As an implementation method, the duration of at least one first start-stop period is equal to the duration of a single first sampling cycle, and the sum of the durations of at least two consecutive first start-stop periods is equal to the duration of a single first sampling cycle. Of course, in specific applications, it is not necessary to set the duration of at least one first start-stop period to be equal to the duration of a single first sampling cycle. For example, as an alternative implementation method, the sum of the durations of every two consecutive first start-stop periods can be set to be equal to the duration of a single first sampling cycle; or, as another alternative implementation method, the sum of the durations of at least two consecutive first start-stop periods can be set to be equal to the duration of a single first sampling cycle, and the sum of the durations of at least three consecutive first start-stop periods can be equal to the duration of a single first sampling cycle.
