Description

Technical Field

[0001] This invention relates to the field of biochemical and immunoassay equipment, and more particularly to a sample rack retrieval method, apparatus, device, and computer-readable storage medium. Background Technology

[0002] In clinical biochemical and immunological applications, a large number of blood or urine samples are transported daily to the sample analyzer's aspiration station via a sample rack retrieval system for chemical composition analysis. Taking a biochemical and immunological analysis pipeline as an example, it typically consists of an analysis unit, a sample rack retrieval system, and an operation unit. The sample rack retrieval system is responsible for functions such as sample loading, scanning, scheduling, transmission, positioning, and retrieval of the sample racks.

[0003] During normal testing, the sample rack testing process is as follows: sample injection - obtaining barcode information - scheduling and distribution - transfer to the sampling position in the analysis department - test completion and return - scheduling and distribution - return to the recycling area. After the sample testing is completed, the sample is generally recycled to the recycling area. Currently, the industry-common recycling method is to push the sample rack one rack distance away from the recycling port. However, the recycling port is usually located at the opposite end away from the front of the machine. Due to the actual conditions of the hospital site, users often can only take the sample rack from the front of the machine. When the depth of the machine is large, users need to reach out with both hands to reach the recycled sample rack from the recycling area. This brings many inconveniences to testers of average or short stature, making the operation of retrieving and transferring samples laborious and posing a risk of unstable sample rack handling.

[0019] If not all of the sample racks to be recycled are scheduled, the unscheduled sample racks are pushed into the remaining recycling compartments by the pushing mechanism. The unscheduled sample racks are stacked sequentially in the remaining recycling compartments toward the user's preset compartment.

[0020] Optionally, a second sensor is provided at the end of the remaining recycling bins that is furthest from the user-preset bin.

[0021] Following the step of pushing the un-dispatched sample racks into the remaining recycling compartments via the propulsion mechanism if not all of the sample racks to be recycled have been scheduled, the method further includes:

[0028] When it is detected that the user's preset storage space is not full, the storage status of the remaining recycling storage space is determined;

[0029] If the remaining recycling compartment is in the first compartment state, then determine whether there is a new sample rack recycling task, wherein the first compartment state is that the remaining recycling compartment contains some sample racks;

[0030] If not, the portion of the sample rack is moved from the remaining compartment to the user-preset compartment using the propulsion mechanism to transfer the portion of the sample rack.

[0031] If the remaining recycling compartment is in the second compartment state, the sample rack to be recycled will be recycled to the user preset compartment according to the sample rack recycling advance distance, wherein the second compartment state is that the remaining recycling compartment is full.

[0059] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0060] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0061] In clinical biochemical and immunological applications, a large number of blood or urine samples are transported daily to the sample analyzer's aspiration station via a sample rack retrieval system for chemical composition analysis. Taking a biochemical and immunological analysis pipeline as an example, it typically consists of an analysis unit, a sample rack retrieval system, and an operation unit. The sample rack retrieval system is responsible for functions such as sample loading, scanning, scheduling, transmission, positioning, and retrieval of the sample racks.

[0062] During normal testing, the sample rack testing process is as follows: sample injection - obtaining barcode information - scheduling and distribution - transfer to the sampling position in the analysis department - test completion and return - scheduling and distribution - return to the recycling area. After the sample testing is completed, the sample is generally recycled to the recycling area. Currently, the industry-common recycling method is to push the sample rack one rack distance away from the recycling port. However, the recycling port is usually located at the opposite end away from the front of the machine. Due to the actual conditions of the hospital site, users often can only take the sample rack from the front of the machine. When the depth of the machine is large, users need to reach out with both hands to reach the recycled sample rack from the recycling area. This brings many inconveniences to testers of average or short stature, making the operation of retrieving and transferring samples laborious and posing a risk of unstable sample rack handling.

[0063] To address the aforementioned issues, this invention provides a sample rack retrieval method. This method offers users an adjustable sample rack retrieval advance distance. Based on this distance, the front area of ​​the sample retrieval zone is designated as a user-preset compartment. After sample testing, samples that have been aspirated are prioritized for allocation to the unfilled user-preset compartments in the sample retrieval zone. Since users can adjust the length of these user-preset compartments within the sample retrieval zone according to their needs, the retrieval distance is more flexible. Once the system automatically retrievals the samples, users can conveniently retrieve the sample rack from the retrieval zone based on their customized user-preset compartments. This avoids the inconvenience of retrieving samples due to excessively long machine bodies, as well as the wasted time and manpower required for sample selection. Therefore, it solves the technical problem of users finding it difficult to conveniently and safely retrieve sample racks using existing sample rack retrieval methods.

[0064] This invention provides a computer-readable storage medium storing a computer program that, when executed by a processor, implements the sample rack retrieval method provided in this invention. The method implemented by the sample rack retrieval program when executed can be referred to in various embodiments of the sample rack retrieval method of this invention, and will not be repeated here.

[0065] Figure 1 A schematic diagram of the operation unit in an embodiment of the present invention is shown. Figure 1 A block diagram is shown that is suitable for implementing an exemplary operating unit of an embodiment of the present invention. Figure 1 The illustrated operating unit is merely an example and should not be construed as limiting the functionality or scope of the embodiments of the present invention. Operating unit: processor, memory, I / O interface, input device, output device.

[0066] A memory for storing at least one control program;

[0067] The stored program is executed by one or more processors to implement the sample scheduling method in this embodiment of the invention, the method comprising:

[0068] System memory may include computer system-readable media in the form of volatile memory, such as random access memory (RAM) and / or cache memory.

[0069] The operation unit can communicate with one or more external input devices (such as keyboards, monitors, etc.) through the I / O interface, and can also communicate with one or more external output devices (printers, monitors, etc.) through the I / O interface.

[0070] The processor performs various functional applications and data processing by running programs stored in memory.

[0071] The following are various embodiments of the sample rack retrieval method of the present invention.

[0072] Reference Figure 2 , Figure 2 This is a flowchart illustrating a first embodiment of the sample rack retrieval method of the present invention. The method is applied to a sample rack retrieval system, which includes a sample retrieval area, and the method includes:

[0073] Step S10: In response to the sample testing completion instruction, determine the sample rack to be recycled;

[0074] Step S20: When the user-preset compartment is not full, the sample rack to be recycled is preferentially scheduled to the user-preset compartment in the sample recycling area so that the user can take the sample rack based on the user-preset compartment. The user-preset compartment is the front area divided from the sample recycling area according to the preset sample rack recycling advance distance.

[0075] In this embodiment, the sample testing completion command can be triggered by the system itself or received from an external source. The user-preset compartment is part of the sample recovery area, and its specific location can be flexibly set according to the actual situation. For example, it can be set to be located in the recovery area near the front of the machine. The part of the sample recovery area other than the user-preset compartment can be used as another type of compartment, or it can be further divided into multiple compartments according to actual needs.

[0076] As a specific implementation method, such as Figure 3 As shown in the diagram, the system includes an insertion area, a return area, a buffer zone, a scheduling area, and a track area. The diagram shows the insertion area, return area, buffer zone, and scheduling area arranged in a single line. The sample insertion area is used to place sample racks to be injected. After the sample racks are placed in the insertion area, they are dispatched by the scheduling area to the front track suction position via the injection channel. After suction is completed, the sample racks are then dispatched to the return area, where the user can retrieve them. Typically, sample racks and sample tubes are equipped with barcode labels. During the process of the sample racks entering the scheduling area via the injection channel, the barcodes are scanned by a barcode scanner to obtain sample rack and sample information. Due to layout limitations, the barcode scanner is not shown in the diagram.

[0077] The system acquires the test location and test status information of the sample rack, identifies the sample racks that have completed testing as sample racks to be recycled, and then initiates the sample rack recycling scheduling command to prioritize the scheduling of the sample racks to the sample recycling area.

[0078] As a specific embodiment, such as Figure 4 As shown, the sample recovery area consists of user-preset storage spaces and remaining recovery storage spaces.

[0079] The process of moving the sample rack to the sample recovery area includes the following situations, with different action procedures corresponding to different stages.

[0080] When the entire sample recovery area is empty, the sample rack is moved from the track area to the sample recovery area via the scheduling area and the recovery channel, which can be divided into two stages.

[0081] The first phase of the retrieval process is as follows: based on the user-preset sample rack retrieval and advancement distance, the storage space is divided, and then the stopping position of the sample rack is determined. That is, the sample rack is first dispatched to the user-preset storage space according to the preset advancement distance until it is full, and an alarm is issued indicating that the user-preset storage space is full when it is full.

[0082] The second-stage recycling process is as follows: when the sample rack in the preset compartment is full, the sample rack is controlled to be recycled in the remaining recycling compartment, the stop position of the sample rack is determined, until the compartment is full, and an alarm prompt that the sample recycling area is full is issued when the compartment is full.

[0083] Once the entire sample recovery area is full, stop transferring samples to the sample recovery area.

[0084] This embodiment provides a sample rack retrieval method. By providing users with an adjustable sample rack retrieval advancement distance, the front area of ​​the sample retrieval zone is divided into user-preset compartments based on this advance distance. After sample testing is completed, samples that have been aspirated are prioritized and dispatched to the unfilled user-preset compartments in the sample retrieval zone. Since users can adjust the length of the user-preset compartment in the sample retrieval zone according to actual needs, the sample rack retrieval distance is more flexible. After the system automatically retrieves the samples, users can conveniently retrieve the sample rack from the retrieval zone based on their customized user-preset compartments. This avoids the inconvenience of retrieving samples due to excessively long machine bodies, as well as the wasted time and manpower required for sample selection. Thus, it solves the technical problem that users cannot conveniently and safely retrieve sample racks using existing sample rack retrieval methods.

[0085] Furthermore, based on the above Figure 2 The first embodiment shown presents a second embodiment of the sample rack retrieval method of the present invention. In this embodiment, before step S10, the method further includes:

[0086] Step S01: Using the sample rack recovery and advancement distance as the boundary, the front area of ​​the sample recovery area near the front of the machine body is designated as the user preset compartment.

[0087] Step S02: The rear area of ​​the sample recovery area away from the front of the fuselage is designated as the remaining recovery compartment.

[0088] In this embodiment, the sample recovery area is divided into two sections. The division of the recovery area is based on the user-preset sample rack recovery and propulsion distance. Using the user-preset sample rack recovery and propulsion distance as the boundary, the section closer to the front of the machine is the preset section, and the section further back is the remaining section. For example... Figure 5 As shown in the figure, the entire sample recovery area is shown. The part indicated by label 1 is the user-preset compartment, and the part indicated by label 2 is the remaining recovery compartment. The dashed arrow indicates the sample rack recovery advancement distance.

[0089] Users can specify the sample rack retrieval and propulsion distance. Preferably, the specific setting limit range is from the initial position of the sample retrieval area to the end position of the sample retrieval area.

[0090] Optionally, the specific setting range can be from the initial position of the sample recovery area to the preset full position minus one. For example, when the user presets the advance distance to halfway through the recovery channel, the sample rack advance distance is halfway through the entire recovery area. When the user presets the advance distance to one minute from the full position of the recovery channel, the sample rack advance distance is the entire recovery area size minus one sample rack distance.

[0091] Optionally, if the user does not specify the recovery propulsion distance, the specific propulsion distance will be determined by the software's default parameters.

[0092] Furthermore, the system includes a propulsion mechanism, and step S20 includes:

[0093] Step S21: If it is detected that neither the user preset compartment nor the remaining recycling compartment is full, the sample rack to be recycled is pushed to the user preset compartment by the pushing mechanism, wherein the sample racks to be recycled are stacked sequentially in the user preset compartment toward the front of the machine body.

[0094] In this embodiment, when the entire sample recovery area is empty, the system prioritizes scheduling the sample racks to be recovered to the user's preset storage location.

[0095] like Figure 3 As shown by the dashed scheduling path, the sample rack to be recovered is pushed to the user-preset sample rack recovery distance by the propulsion mechanism.

[0096] It can be determined that after the user specifies the recovery and propulsion distance, as long as the recovery position is specified as the user's preset compartment, the distance that the sample rack is pushed forward each time is the recovery and propulsion distance specified by the user. The sample racks are stacked sequentially in the user's preset compartments in the direction closer to the front of the machine.

[0097] Furthermore, a first sensor is installed at the end of the user-preset compartment furthest from the remaining recycling compartment. After step S21, the method further includes:

[0098] Step A1: When the number of sample racks to be recycled pushed to the user preset compartment by the propulsion mechanism is accumulated to the first sensor, causing the first sensor to be triggered, it is determined that the user preset compartment is full.

[0099] Step A2: Pause the advance of the sample rack to be recycled to the user-preset compartment, generate and output a first alarm prompt, wherein the first alarm prompt is used to indicate that the sample recycling area is about to be full or the user-preset compartment is full.

[0100] In this embodiment, the first sensor can be a reflection sensor, a gravity sensor, a pressure sensor, etc. The user preset compartment can determine whether the sample rack in the preset compartment is full by detection or other methods. The installation position of the first sensor can be set at the left or right side or left or right bottom surface of the end of the user preset compartment (i.e., the end away from the remaining recycling compartment). When the first sensor detects a collision signal, it is considered that the sample rack in the user preset compartment is full, and at this time the system stops pushing samples into the preset compartment.

[0101] Understandably, when the preset position is full, the operation department software interface will issue an alarm prompt: the preset position is full or the sample recovery area is about to be full.

[0102] Optionally, alarm notifications can be sent to the user through audible alarms, pop-up alarms in the software interface, or hidden alarms.

[0103] like Figure 6 As shown, if the user retrieves a sample from the user-preset compartment and the first sensor trigger signal disappears, the next sample rack retrieval will still proceed according to the user-preset sample rack retrieval advance distance; however, if the first sensor signal does not disappear, the retrieval of samples into the user-preset compartment will be paused.

[0104] Furthermore, after step A2, the following steps are also included:

[0105] Step A3: If not all of the sample racks to be recycled have been scheduled, the unscheduled sample racks are pushed into the remaining recycling compartments by the pushing mechanism. The unscheduled sample racks are stacked sequentially in the remaining recycling compartments toward the user's preset compartment.

[0106] In this embodiment, the remaining recycling space is the total sample recycling area space minus the user-preset space. When the user-preset space is full, the sample racks are arranged according to... Figure 7 The sample holder is advanced by the default advance distance indicated by the solid line arrow (determined by the software's default parameters).

[0107] like Figure 7As shown in the solid line scheduling path, the sample rack is pushed to the sample recovery area. To avoid the risk of injury to the user and the pushing mechanism during the recovery process, for example, when the preset number of sample racks in the compartment is full, if the pushing distance remains unchanged, there is a risk that the pushing device may pinch the user's hands while the sample rack is being retrieved, causing sample spillage or user injury. Therefore, the system's default sample rack recovery pushing distance is one sample rack distance from the recovery channel.

[0108] It can be determined that as long as the recycling location is specified as the remaining recycling compartment, the distance that the sample rack advances each time it is the distance of one sample rack from the recycling channel. The sample racks are stacked sequentially in the remaining recycling compartments towards the user's preset compartment.

[0109] Furthermore, based on the second embodiment described above, a third embodiment of the sample rack recycling method of the present invention is proposed. In this embodiment, a second sensor is provided at the end of the remaining recycling compartment furthest from the user-preset compartment.

[0110] Following step A3, the following is also included:

[0111] Step A4: When the number of sample racks to be recycled in the remaining recycling bin is pushed to the second sensor by the propulsion mechanism, causing the second sensor to be triggered, it is determined that the remaining recycling bin is full.

[0112] Step A5: Pause the advancement of the sample rack to be recycled to the remaining recycling compartment, generate and output a second alarm message, wherein the second alarm message is used to indicate that the sample recycling area is full.

[0113] In this embodiment, the second sensor can be a reflection sensor, gravity sensor, pressure sensor, etc. The remaining recovery compartment can be determined by the second sensor to determine whether the sample racks in the remaining recovery compartment are full. The second sensor can be installed at the front (near the recovery channel) of the remaining recovery compartment, on the left or right sides or the left or right bottom surfaces, etc. When the second sensor's detection signal is triggered, it is considered that the sample racks in the remaining recovery compartment are full, and the system will stop pushing samples into the recovery area. Understandably, when the remaining recovery compartment is full, the operation unit software interface will issue an alarm prompt: the sample recovery area is full. Optionally, the alarm prompt can be sent to the user through an alarm sound, a pop-up alarm in the software interface, or a hidden alarm.

[0114] Furthermore, the system also includes a sample buffer, and after step A5, it further includes:

[0115] Step A6: If not all of the samples to be recycled have been scheduled, the unscheduled samples to be recycled will be temporarily stored in the sample buffer.

[0116] In this embodiment, the sample rack retrieval system also includes a buffer zone, which contains at least one storage location for storing sample racks. Its function is to provide a buffer storage area for sample racks. The buffer is a test state in which the sample rack is in the buffer zone. The test state includes states such as sample loading storage, storage during testing, and automatic retest storage, which are used to assist in the scheduling of sample racks. The number of its locations can be set according to the actual situation.

[0117] When the sample recycling area is full, the sample racks to be recycled can be temporarily stored in the sample buffer area. Once the user retrieves the sample from the recycling area, the sample racks will be dispatched to the sample recycling area.

[0118] Furthermore, after step S10, the following steps are also included:

[0119] Step B1: When it is detected that the user's preset storage space is not full, determine the storage status of the remaining recycling storage space;

[0120] Step B2: If the remaining recycling compartment is in the first compartment state, then determine whether there is a new sample rack recycling task, wherein the first compartment state is that the remaining recycling compartment contains some sample racks;

[0121] Step B3: If not, the partial sample rack is moved from the remaining compartment to the user-preset compartment by the propulsion mechanism to transfer the partial sample rack.

[0122] Step B4: If the remaining recycling compartment is in the second compartment state, the sample rack to be recycled is recycled to the user preset compartment according to the sample rack recycling advance distance, wherein the second compartment state is that the remaining recycling compartment is full.

[0123] In this embodiment, for the first storage location, if there are still vacancies (empty or not full) in the user-preset storage location, and there are one or more sample racks in the remaining recycling location, if there are no new sample racks to be added to the sample recycling area, one or more sample racks in the remaining recycling area can be transferred to the user-preset storage location.

[0124] As one specific implementation method, refer to Figure 8 When the user's preset storage space is full and there are some sample racks in the remaining recycling space, the user can recycle the sample racks in the user's preset storage space. Once all the sample racks in the preset storage space have been recycled and there are no new sample racks to be recycled, the user can activate the sample rack recycling button to control the sample racks to be moved from the remaining recycling space to the user's preset storage space.

[0125] Understandably, the sample rack recycling button can be a physical button or a virtual button, and the activation method can be either physical button triggering or software virtual button triggering.

[0126] Understandably, the control of the sample racks is to move them from the remaining compartments to the preset compartments, that is, to move the sample racks in the remaining compartments according to the user-preset moving distance, and to transfer all the sample racks in the remaining compartments to the preset compartments.

[0127] In the second compartment state, if the second sensor of the remaining recycling compartment remains triggered and the first sensor of the user-preset compartment is not triggered, the sample rack will be recycled according to the user-preset propulsion distance, pushing the sample rack into the user-preset compartment. As the number of sample racks stored in the user-preset compartment gradually increases, the propulsion mechanism will not be able to advance the sample rack recycling distance. Then, the sample rack will stop advancing when the detection sensor of the user-preset compartment is triggered.

[0128] Furthermore, based on the first embodiment described above, a fourth embodiment of the sample rack retrieval method of the present invention is proposed. In this embodiment, before step S10, the method further includes:

[0129] Step S001: Obtain the test position of the sample rack and monitor the test status of all samples in the sample rack in real time;

[0130] Step S002: When the test status of all samples in the sample rack is detected to be completed, the sample test completion command is triggered.

[0131] Step S10 includes:

[0132] Step S11: In response to the sample testing completion instruction, the sample rack where all samples have been tested is identified as the sample rack to be recycled.

[0133] In this embodiment, reference Figure 9 This interface displays the testing status information of all sample racks. The status interface updates when the status of the sample rack and its samples changes. The testing status of the sample racks in the sample rack retrieval system can include: pending testing, testing in progress, sample aspiration completed, temporary storage during testing, and completed. The sample testing status can be displayed using text, images, or color status.

[0134] refer to Figure 9The interface for the sample rack position and status is further explained below. The top left corner of the interface displays the current location of the sample rack, which includes the sample buffer zone, track zone, and retrieval zone. The first column on the left side of the status bar displays the sample rack number, consisting of letters followed by a 3-digit code. The first row of numbers 1-10 represents each sample position on the rack, and the circle below each sample position indicates the sample's testing status. Different colors, patterns, or text can be used to represent the testing status, such as green for complete aspiration and red for incomplete aspiration. The right column displays the rack status, which can be shown through text, patterns, or colors. If the sample rack is in the track zone, the status includes "Testing (sample being aspirated)," "Waiting for Test (waiting in the pre-absorption buffer)," and "Moving (switching to another analysis section, returning, etc.)." If the sample rack is in the retrieval zone, the status includes "Completed" and "Incomplete (due to analysis section malfunction, etc.)."

[0135] pass Figure 9 The sample rack status interface shown can obtain the test completion status of the samples in real time. Under normal circumstances, the sample rack retrieval scheduling process can be started after all samples in the sample rack have been aspirated.

[0136] The present invention also provides a sample rack retrieval system, such as Figure 10 As shown in the figure, an embodiment of the present invention illustrates the layout and structural composition of a sample rack recovery system, including a front-end track, a scheduling module, and a sample rack for carrying samples. The sample analysis module can be a biochemical analyzer or an immunoassay analyzer.

[0137] The system includes: a sample placement area 101, a sample introduction channel 102, a priority sample placement area 103, a sample buffer zone 104, a scheduling area 105, a recovery channel 106, remaining (recovery) compartments 107, (user) preset compartments 108, a sample recovery area 109 composed of the remaining recovery compartments 107 and the user preset compartments 108, a remaining compartment detection sensor 110, a preset compartment detection sensor 111, a track area 112, and an analysis module 113. In addition, structures such as the track (including a regular channel, an emergency channel, a return channel, and a track-changing mechanism), scanning equipment, and a scheduling trolley are not directly observable on the system surface and are not shown in the figure.

[0138] In addition, the system also includes an operation unit, which can be connected to the sample analyzer via wired or wireless means for system operation control, running operation software, completing sample data entry and test result output, and monitoring and scheduling control of samples.

[0139] Furthermore, this embodiment of the invention describes the structure of the sample recovery area 109. The sample recovery area 109 consists of user-preset compartments 108 and remaining recovery compartments 107, wherein the remaining compartments and preset compartments are used to store sample racks recovered at different times. It is understood that the number of sample racks stored in the preset compartments and remaining compartments is adjustable and can be adaptively adjusted according to user needs and client scenarios.

[0140] Optionally, the number of sample racks stored in the preset compartments ranges from the initial position of the sample recovery area to the preset compartment full position minus 1, that is, between the remaining compartment detection sensor 110 and the preset compartment detection sensor 111 minus 1.

[0141] Optionally, the sample recycling area 109 may employ a propulsion mechanism, which can push the sample rack from the recycling channel 106 to the user-preset compartment 108, push the sample rack from the recycling channel 106 to the remaining recycling compartment 107, and push the sample rack from the remaining recycling compartment 107 to the user-preset compartment 108.

[0142] refer to Figure 4 The installation positions shown for the remaining storage space detection sensor 110 and the preset storage space detection sensor 111 represent one installation method in this embodiment. When the number of sample racks in the user's preset storage space 108 reaches the preset storage space detection sensor 111, the sensor is triggered, and the software alarm indicates that the sample rack is about to be full. At this time, the sample racks are stopped from being pushed into the user's preset storage space 108. When the number of sample racks in the remaining recycling storage space 107 reaches the remaining recycling storage space sensor in the triggered state, the software alarm indicates that the recycling space is full, and the recycling area stops recycling samples.

[0143] It can be determined that the preset compartment detection sensor is installed at the end of the user preset compartment 108 (near the front of the machine), and the sample rack stacking direction of the preset compartment is towards the preset compartment detection sensor. The remaining compartment detection sensor is installed at the entrance of the remaining recycling compartment 107 (near the recycling channel 106). The sample rack advances a distance equal to the distance of one sample rack of the remaining compartment detection sensor, and the sample rack stacking direction of the remaining recycling compartment is towards the user preset compartment. When the last sample rack enters the remaining recycling compartment 107, the sample rack stops at the remaining compartment detection sensor 110. At this time, the advancing mechanism collides with the remaining compartment detection sensor, triggering a collision signal, i.e., an alarm indicating that the recycling area is full.

[0144] It is understood that the installation positions shown for the remaining storage space detection sensor 110 and the preset storage space detection sensor 111 in the figure are one installation method in this embodiment, including but not limited to installation on the left and right side walls, left and right bottoms, etc. of the recycling system.

[0145] Furthermore, this embodiment of the invention describes the structure of the retrieval channel 106. The retrieval channel runs through the sample retrieval area and the sample placement area. The sample rack can be dispatched to the sample retrieval area or the sample placement area via the retrieval channel, and can be adaptively selected according to different dispatch scenarios. Sample racks that have been successfully dispatched are dispatched to the sample retrieval area via the retrieval channel.

[0146] Understandably, the sample scheduling area 105 has bidirectional movement capabilities, allowing it to switch between different positions within the sample buffer zone. Simultaneously, it transports the sample rack from the sample inlet channel to the track area, and then transports the sample rack from the track area to the recovery channel.

[0147] Furthermore, to achieve the above objectives, the present invention also provides a sample rack retrieval device, the device comprising at least a sample retrieval area and a sample scheduling area, the sample retrieval area consisting of user-preset compartments and remaining retrieval compartments, the number of sample racks stored in the user-preset compartments and remaining retrieval compartments being adjustable, the device being used for:

[0148] In response to the sample testing completion instruction, determine the sample rack to be recycled;

[0149] When the user-preset compartment is not full, the sample rack to be recycled is preferentially dispatched to the user-preset compartment via the scheduling area, so that the user can take the sample rack based on the user-preset compartment. The user-preset compartment is the front area divided from the sample recycling area according to the preset sample rack recycling advance distance, and the remaining recycling compartment is the remaining area in the sample recycling area excluding the user-preset compartment.

[0150] The present invention also provides a sample rack recycling device.

[0151] The sample rack retrieval device includes a processor, a memory, and a sample rack retrieval program stored in the memory and executable on the processor, wherein when the sample rack retrieval program is executed by the processor, it implements the steps of the sample rack retrieval method as described above.

[0152] The method implemented when the sample rack retrieval procedure is executed can be referred to in various embodiments of the sample rack retrieval method of the present invention, and will not be repeated here.
