The numbering of the components as such, e.g., "first", "second", etc., is used herein only to distinguish the objects as described, and does not have any sequential or technical meaning. The term "connected" and "coupled" when used in this application, unless otherwise indicated, includes both direct and indirect connections (couplings).
In one embodiment, the present invention provides an in vitro test device for testing a sample. Referring to fig. 1, the in-vitro testing apparatus of an embodiment may include a sample unit 10, a reagent unit 20, an assay unit 30, a controller 40, and an input unit 50, and may further include a display unit 60, which will be described in detail below.
The sample unit 10 is used for carrying a sample to be tested, and the sample is sucked and supplied to the measurement unit 30. The sample unit 10 of an embodiment includes a plurality of input areas 11, a plurality of recovery areas 12, and a scheduling unit 13, wherein the input areas 11 are used for carrying sample racks to be injected, the recovery areas 12 are used for recovering the sample racks, and the scheduling unit 13 may operate in units of sample racks, that is, the scheduling unit 13 is used for scheduling the sample racks, which is further described below.
The sample rack can carry a plurality of sample containers (such as test tubes) for holding samples, the sample unit 10 is arranged by taking the sample rack as a unit, and the sample racks are respectively arranged to the sample sucking position by the arranging unit 13 so as to suck the samples on the sample racks and then provide the samples to the measuring unit 30 for testing. Referring to fig. 2, the sample block 10 is provided with a plurality of input areas and recovery areas, and two input areas and two recovery areas are shown in a schematic view. The placing area is used for placing a sample rack to be subjected to sample introduction, after the sample rack to be subjected to sample introduction is placed in the placing area by an operator, the sample part 10 dispatches the sample rack in the placing area to a sample sucking position through the dispatching part 13, the sample rack after sample sucking is dispatched in the recovery area, and the operator can take out the sample rack from the recovery area. Generally, barcode labels and the like are provided on the sample rack and the sample container, and the sample rack is scanned by the sample unit 10 during the process of being dispatched from the loading area to the sample aspirating position, and the sample unit 10 can acquire, for example, the type and identification number of the sample rack, and acquire, for example, the identification number of the sample, the position information in the sample rack, and the test item information by scanning the barcode labels.
Referring to fig. 3, the sample block 10 of an embodiment may further include a buffer 14, for example, a buffer is disposed in the sample block 10 to assist in the scheduling of the sample racks and provide a transfer and buffering location for the sample racks. The buffer 14 herein is capable of storing one or more sample racks, and the buffer 14 herein may be sized and dimensioned according to the daily throughput or throughput of the in vitro testing device. The cache 14 has many functions, several of which are tried below.
One particular purpose of the buffer area 14 may be to serve as a transfer station for the sample racks during their dispatch from the loading area to the pipetting position, for buffering the sample racks waiting for pipetting. Due to the existence of the buffer area 14, a plurality of sample racks are dispatched to the buffer area 14 in batches, and then the dispatching part 13 dispatches the sample racks to the sample sucking positions from high to low in sequence according to the sample sucking priority of the sample racks. For example, a sample rack requiring an emergency treatment has a higher priority than a normal sample rack, and a sample rack which is applied for a test first in the normal sample rack has a higher priority than a sample rack which is applied for a test later. One structure of the buffer area 14 is shown in fig. 4, the buffer area 14 includes a plurality of channels, each of which can hold a sample rack, and the scheduling component 13 can schedule the sample rack buffered by the channel from any one of the channels, for example, to a sample sucking position or a recovery area.
A specific function of the buffer 14 may also be to buffer a sample rack after sampling, so that a sample on the sample rack may wait for a test result of an item at the buffer 14, if the test result of the item is normal, the sample rack may be dispatched from the buffer 14 to a recovery area for recovery, if the test result of the item is abnormal, it indicates that a corresponding sample on the sample rack needs to retest the item, the sample rack may be dispatched from the buffer 14 to a sample suction position, the corresponding sample may be suctioned to retest the item with the abnormal test result, and then the sample rack may continue to return to the buffer to wait for whether the test result of the retested item is normal, or may be directly dispatched to the recovery area, i.e., no longer waits for the test result of the retested item. It should be noted that, the abnormal test result of a certain item of the sample generally means that at least one test parameter result of the item is not within a preset range, and if the test parameter results of the item of the sample are all within the corresponding preset ranges, the test result of the item is normal.
The sample part 10 in one embodiment can acquire the state of the sample rack and the sample thereof, wherein the sample of the sample rack refers to the sample carried on the sample rack. In particular, the sample block 10 may acquire the state of the sample rack by scanning as described above in conjunction with some sensors. In one embodiment, the states of the sample rack and the samples thereof may include the stage of the samples in the sample rack in the testing process, the corresponding states of the sample rack and the samples thereof in the testing process, the positions of the sample rack and the samples thereof, and the like.
This will be explained in detail below.
The stage of the sample in the sample rack in the testing process comprises the following steps: the method comprises a test application stage, a sample sucking waiting stage, a sample sucking finishing stage, a project test result waiting stage and the like.
The corresponding states of the sample rack in the test process include: sample rack normal and sample rack abnormal, etc. An example rack exception may include: sample rack identification number duplication or sample rack barcode scanning failure, etc.
The corresponding states of the samples in the sample rack in the test process comprise: normal and abnormal samples, etc. Sample exceptions in one embodiment may include: sample errors, no detection items of the sample after the test application stage is finished, sample bar code errors, abnormal item test results of the sample, insufficient reagents and incapability of completing sample test and the like. Sample errors may include the following: and judging that the sample is insufficient, and the needle tube for sucking the sample is blocked or collides with other parts during sample sucking. Sample barcode errors may include the following: sample barcode duplication, failure of sample barcode identification or failure of sample barcode parsing, and the like. The position of the sample rack can give information such as whether the sample rack is in the placing area, the sample sucking position, the buffer area or the recovery area. The position of the sample refers to the position of the sample on its sample holder.
The abnormal state of the sample rack herein includes abnormal state of the sample rack or abnormal state of the sample, that is, for any sample rack, the abnormal state of the sample rack is judged as long as any one of the abnormal state of the sample rack and the abnormal state of the sample on the sample rack occurs.
The above is a description of the sample part 10 of the present invention. It should be noted that, in the present invention, the placing area carries or places the sample, including two ways, that is, the placing area directly carries the sample and indirectly carries the sample, for example, the placing area can carry a plurality of sample racks, each sample rack can carry a plurality of samples, and for example, the placing area can carry a basket that can be placed in and taken out, and the basket can carry a plurality of samples. Similarly, a sample rack carrying a plurality of samples may refer to a sample rack carrying a plurality of sample containers, each sample container holding a sample. Similarly, a basket carries a plurality of samples, which may also be referred to as a basket that carries a plurality of samples by carrying a plurality of sample holders.
The reagent unit 20 is used for carrying a reagent, and supplies the reagent to the measurement unit 30 after the reagent is aspirated.
The measuring unit 30 is used for measuring the sample to obtain the test result of the sample.
The controller 40 is used to control the sample part 10, the reagent part 20 and the assay part 30 to complete the project test of the sample.
The input unit 50 is used for inputting by a user and assisting the user in performing man-machine interaction with the in-vitro testing apparatus. The input unit 50 may be implemented by a mouse, a keyboard, a track ball or a joystick.
The display section 60 is used to display information. The display unit 60 may be implemented by using a display screen, and certainly, the functions of the input unit 50 and the display unit 60 may also be implemented by using a display screen with a touch function.
In an embodiment of the present invention, the input unit 50 is configured to allow a user to input a selection command for receiving a sample rack and a retrieval command for taking out a sample rack, and when the input unit 50 receives the selection command for receiving a sample rack and the retrieval command for taking out a sample rack, the controller 40 is configured to determine a selected sample rack according to the selection command and control the scheduling unit 13 to schedule the selected sample rack to the recovery area 12 according to the retrieval command. By the mode, a user can schedule the sample racks to be taken out to the recovery area 12 according to the sequence of the time for completing the test of the samples without waiting for the in-vitro detection equipment, so that the user can directly select the sample racks to be taken out, and then the in-vitro detection equipment schedules the sample racks selected by the user to the recovery area 12 in a priority mode or in an in-line mode.
In one embodiment, the controller 40 controls the scheduling component 13 to schedule the selected sample rack to the recovery area 12, and the following strategy can be adopted.
The controller 40 determines whether the selected sample rack is currently scheduled to be blocked by another sample rack on the path to the recovery area 12. It should be noted that the sample assembly 10 may include one or more paths for dispatching the sample rack to the recovery area 12, and this may also include several paths for dispatching the sample rack to the recovery area only, that is, the paths for dispatching the sample rack to the recovery area only are used for dispatching the sample rack to the recovery area only, and are not used for other purposes such as dispatching the sample rack from the loading area to the suction position. If the sample block 10 includes a plurality of paths for the sample racks to be dispatched to the recovery area 12, the controller 40 determines that the selected sample rack is blocked by another sample rack on the path currently dispatched to the recovery area 12 only if the paths are blocked by another sample rack, so that the selected sample rack cannot be dispatched to the recovery area 12 through the paths, otherwise, the controller 40 determines that the selected sample rack is not blocked by another sample rack on the path currently dispatched to the recovery area 12.
When the controller 40 determines that the selected sample rack is currently scheduled to the recycling area 12 without being blocked by other sample racks, the controller controls the scheduling component 13 to schedule the selected sample rack directly to the recycling area 12. If the sample block 10 has multiple paths for the sample racks to be dispatched to the recovery area 12, the controller 40 can arbitrarily select a path that is not blocked by other sample racks, and the selected sample rack is dispatched to the recovery area 12 through the selected path.
When the controller 40 judges that other sample racks are blocked in the path of the selected sample rack currently scheduled to the recovery area 12, the scheduling component 13 is controlled to schedule the selected sample rack to the buffer area 14 for waiting; in the process that the selected sample rack waits in the buffer area 14, when it is determined that no other sample rack is blocked in the path of the selected sample rack scheduled from the buffer area 14 to the recovery area 12, the control scheduling unit 13 schedules the selected sample rack from the buffer area 14 to the recovery area 12.
In one embodiment, in order to facilitate the user to observe the status of the sample rack and the sample thereof in the in vitro testing apparatus, and to facilitate the user to select the sample rack, a status interface can be displayed through the display unit 60. Specifically, the controller 40 acquires the states of each sample rack and its samples — for example, the controller 40 acquires these states through the sample unit 10 and displays the states of each sample rack and its samples by generating a state interface in the display unit 60, and when there is a change in the states of the sample racks and their samples, the controller 40 updates the state interface of the display unit 40. The sample rack and the state of the samples are described in detail above in the description of the sample part 10 and will not be described again. The state of the sample rack and its samples changes, meaning that the state of either the sample rack or the samples on the sample rack changes, the controller 40 updates the state interface of the display unit 60.
By displaying the status interface on the display unit 60, the user can observe the status of each sample rack and its sample, and select the sample rack that is currently taken out, for example, when an abnormality of the sample rack is observed or an abnormality of the sample is observed, the corresponding sample rack is selected and taken out.
Referring to fig. 5, an example of a status interface is shown, in which the number of letters plus four digits in the status interface represents the identification number of the sample rack, such as E0001, N0002, S0001, etc. Each sample rack may carry 10 samples, and the 10 circles in the same row as the identification number of the sample rack represent the 10 samples carried on that sample rack. An embodiment may represent the state of a sample by filling in different colors, patterns, or symbols with circles representing the sample. For example, a, b, c, d and e in fig. 6 are respectively used to indicate that the sample is normal, the sample is wrong, the sample has no detection item after the application stage, the sample barcode is wrong, and the item test result of the sample is abnormal. Similarly, the normal sample rack and the abnormal sample rack can be distinguished by coding the identification numbers of the sample racks with different colors in the status interface, for example, the identification number coded in black indicates the normal sample rack, and the identification number coded in red indicates the abnormal sample rack.
In order to facilitate the user to select the sample rack and input the taking command, as shown in fig. 7, in an embodiment, the status interface may have an input box for the user to input the identification number of the sample rack through the input unit 50, and after the user inputs the identification number of the sample rack in the input box, the user clicks the button of the sample rack to complete the operation of taking the sample rack that the user wants to take. On the other hand, for the in vitro testing apparatus, when the user clicks the button for taking out the sample rack, the controller 40 determines the sample rack with the identification number as the selected sample rack by receiving the identification number currently in the input box, and controls the scheduling component 13 to schedule the selected sample rack to the recovery area 12. In one embodiment, the controller 40 obtains the click information of the user on the status interface through the input unit 50, determines the sample rack corresponding to the identification number or the graphic symbol as the selected sample rack when the identification number or the graphic symbol of the obtained sample rack is clicked, and then controls the dispatching unit 13 to dispatch the selected sample rack to the recovery area 12 when the user clicks the button for taking out the sample rack. It should be noted that the graphic symbol of the sample rack is not shown in the drawing, and those skilled in the art will understand that a schematic icon of a sample rack can be generated and displayed on the same row of the identification number of the sample rack and close to the identification number to represent the sample rack of the identification number.
In order to save time and effort for the user to search for a problematic sample rack and a sample, in an embodiment, when the abnormal state of the sample rack is acquired, the controller 40 sets the abnormal state sample rack as a selected sample rack, and controls the scheduling component 13 to schedule the selected sample rack to the recovery area. It should be noted that the abnormal state of the sample rack herein includes an abnormal state of the sample rack or an abnormal state of the sample, that is, for any sample rack, the abnormal state of the sample rack is determined as long as any one of the abnormal state of the sample rack and the abnormal state of the sample on the sample rack occurs.
The above are some illustrations of the in vitro test device of the present invention.
Referring to fig. 8, the present invention further discloses a sample processing system, which includes a placing area 71, a plurality of recycling areas 72, and a scheduling component 73. The placing area 71 is used for bearing a sample rack to be subjected to sample introduction; the recovery area 72 is used for receiving a sample rack to be recovered; the dispatching component 73 is used for dispatching the sample rack, for example, dispatching the sample rack to be sampled from the placing area 71 to a sample sucking position for sucking, for example, dispatching the sample rack with completed test to the recovering area 73. It should be noted that while FIG. 8 shows a schematic representation of a sample processing system having two input regions and two recovery regions, those skilled in the art will appreciate that the present invention is not intended to limit the sample processing system to having only two input regions and two recovery regions.
The basic workflow of a sample processing system of an embodiment is as follows. After the sample rack to be sampled is placed in the placing area 71 by an operator, the sample processing system dispatches the sample rack in the placing area 71 to the sample sucking position through the dispatching component 73, and the sample rack after sample sucking is dispatched to the recovery area 72, so that the operator can take out the sample rack from the recovery area 72. Generally, barcode labels and the like are provided on the sample rack and the sample container, and the sample rack is scanned by the sample processing system during the process of being dispatched from the input area 71 to the sample aspirating position, and the sample processing system can acquire, for example, the type and identification number of the sample rack, and acquire, for example, the identification number of the sample, the position information in the sample rack, and the test item information by scanning the barcode labels.
Referring to fig. 9, the sample processing system of an embodiment may further include a buffer 74, where the buffer 74 is used to assist the scheduling of the sample rack and provide a transfer and buffer location for the sample rack. The buffer 74 may be described with reference to the buffer 14 of the sample block 10, and the functions and functions of the two may be the same, and will not be described again.
The sample processing system of the present invention may include a controller 75 for controlling the operation of the scheduling unit 73 in response to the selection command and the retrieval command. For example, the controller 75 determines the selected sample rack in response to the selection command, and controls the scheduling part 73 to schedule the selected sample rack to the recovery area 72 in response to the retrieval command. In one embodiment, the controller 75 controls the scheduling component 73 to schedule the selected sample rack to the recovery area 72, and the following strategy can be adopted.
The controller 75 determines whether the selected sample rack is currently blocked by another sample rack on the path dispatched to the recovery area 72. It should be noted that the sample processing system may include one or more paths for dispatching the sample rack to the recovery area 72, and this may also include a plurality of paths for dispatching the sample rack only to the recovery area, that is, the paths for dispatching the sample rack only to the recovery area do not serve other purposes such as dispatching the sample rack from the loading area to the suction position, and only the sample rack is dispatched to the recovery area. If the sample processing system includes multiple paths for the sample racks to be dispatched to the recovery area 72, the controller 75 determines that there is another sample rack block on the path where the selected sample rack is currently dispatched to the recovery area 72 only if the paths are blocked by another sample rack, so that the selected sample rack cannot be dispatched to the recovery area 72 through the paths, otherwise, the controller 75 determines that there is no other sample rack block on the path where the selected sample rack is currently dispatched to the recovery area 72.
When the controller 75 determines that the selected sample rack is currently scheduled to the recycling area 72 without being blocked by other sample racks, the controller 73 controls the scheduling component 73 to schedule the selected sample rack directly to the recycling area 72. If the sample processing system has multiple paths for the sample racks to be dispatched to the recovery area 72, the controller 75 can optionally select a path that is not blocked by other sample racks, and cause the selected sample rack to be dispatched to the recovery area 72 via the selected path.
When the controller 75 judges that other sample racks are blocked in the path of the selected sample rack currently scheduled to the recovery area 72, the scheduling component 73 is controlled to schedule the selected sample rack to the buffer area 74 to wait; in the process that the selected sample rack waits in the buffer 74, when it is determined that no other sample rack is blocked in the path of the selected sample rack from the buffer 74 to the recovery 72, the control scheduling unit 73 schedules the selected sample rack from the buffer 74 to the recovery 72.

To facilitate the user's selection of a sample rack and the input of a retrieval command, referring back to fig. 7, in an embodiment, the status interface may have an input box for the user to input the identification number of the sample rack through the input part 76, and after the user inputs the identification number of the sample rack in the input box, the user clicks the button of the sample rack to complete the operation of retrieving the sample rack that the user wants to retrieve. With the sample processing system, when the user clicks the button for taking out a sample rack, the controller 75 determines the sample rack of the identification number as the selected sample rack by receiving the identification number currently in the input box, and controls the scheduling part 73 to schedule the selected sample rack to the recovery area 72. In one embodiment, the controller 75 obtains the click information of the user on the status interface through the input unit 76, determines the sample rack corresponding to the identification number or the graphic symbol as the selected sample rack when the identification number or the graphic symbol obtained from the sample rack is clicked, and then controls the dispatching unit 73 to dispatch the selected sample rack to the recovery area 72 when the user clicks the button for taking out the sample rack. It should be noted that the graphic symbol of the sample rack is not shown in the drawing, and those skilled in the art will understand that a schematic icon of a sample rack can be generated and displayed on the same row of the identification number of the sample rack and close to the identification number to represent the sample rack of the identification number.
In order to save time and effort for the user to search for a problematic sample rack and a sample, in one embodiment, when the abnormal state of the sample rack is acquired, the controller 75 sets the abnormal state sample rack as a selected sample rack, and controls the scheduling unit 73 to schedule the selected sample rack to the recovery area 72. It should be noted that the abnormal state of the sample rack herein includes an abnormal state of the sample rack or an abnormal state of the sample, that is, for any sample rack, the abnormal state of the sample rack is determined as long as any one of the abnormal state of the sample rack and the abnormal state of the sample on the sample rack occurs.
