The transfer mechanism 210 may transfer the sample tube by clamping, rail transport, or the like.

The dispatch mechanism 310 is used to move a sample tube to a processing station 410. A plurality of sample tube positions 311 are provided along the extending direction of the dispatch mechanism 310, the sample tube positions 311 include accommodating chambers capable of accommodating sample tubes, and the transfer mechanism 210 places the sample tubes at the corresponding sample tube positions 311.

To increase the processing efficiency of the sample analyzer, the processing station 410 is secured to an area of the dispatch mechanism 310 such that the sample analyzer processes sample tubes located within the processing area.

After the transfer mechanism 210 places the sample tube into the dispatch mechanism 310, the dispatch mechanism 310 obtains an operation command corresponding to the sample tube, where the operation command includes, but is not limited to, a position, a number, and a sample injection mode of the sample tube. The scheduling mechanism 310 includes a power source for driving the transmission of the scheduling mechanism 310, the power source controlling the transmission distance of the scheduling mechanism 310 based on the step size. After receiving the operation instruction, the scheduling mechanism 310 selects a corresponding step size based on the operation instruction, and drives the sample tube based on the selected step size, so that the sample tube is located in the processing area. The step length is the pulse equivalent of the power source.

Further, the sample injection module 10 may be provided with a plurality of sample injection modes according to sample injection requirements of the sample analyzer. For example, the sample injection mode may include a regular sample injection mode in which the transfer mechanism 210 sequentially places the sample tubes into the sample tube positions 311 such that the dispatch mechanism 310 sequentially drives the sample tubes into the processing region according to the order of the sample tube positions 311; in emergency and/or re-diagnosis sample mode, the dispatch mechanism 310 directly drives the emergency and/or re-diagnosis sample tubes into the processing area in order to facilitate the sample analyzer to preferentially detect the sample tubes in need of emergency and/or re-diagnosis.

In this embodiment, the sample area 110 of the sample injection module 10 is used for placing a sample tube, and the sample tube is used for storing a sample; the transfer mechanism 210 is used for transferring the sample tube; a plurality of sample tube positions 311 are arranged along the extending direction of the dispatching mechanism 310, and the transfer mechanism 210 places the sample tubes at the corresponding sample tube positions 311; at least one processing station 410 is arranged along the extension direction of the dispatching mechanism 310 for processing the sample tubes located in the processing region; the scheduler 310 selects a corresponding step size based on the operation instruction and drives the sample tube based on the selected step size to locate the sample tube within the processing region. The scheduling mechanism 310 of the embodiment selects the corresponding step length to drive based on the operation instruction, and when there is a requirement for a review or emergency, the scheduling mechanism 310 can directly schedule the sample tube for the review or emergency, the sample injection module 10 does not need to return the sample tube being detected, the flow is simple, and the improvement of the sample injection efficiency is facilitated.

Optionally, the sample injection module 10 further includes a detection mechanism, where the detection mechanism is disposed in the sample area 110 and is used for detecting whether the sample rack or the sample carrying mechanism of the sample area 110 is in place, and the detection mechanism is further used for acquiring whether the sample rack or the sample carrying mechanism of the sample area 110 has information, so that a user can load, unload or adjust the sample according to whether the sample rack or the sample carrying mechanism of the detection mechanism has information, and the use experience of the user is improved.

Optionally, the operation instruction is an emergency instruction, where the emergency instruction includes a position, number, etc. of sample tubes, the sample injection module 10 marks the sample tube with an emergency requirement as an emergency sample tube, the transfer mechanism 210 stops the current transfer operation, and the dispatch mechanism 310 stops the current dispatch operation, so that the transfer mechanism 210 and the dispatch mechanism 310 preferentially transfer the emergency sample tube into the processing area.

Specifically, the user places the emergency sample tube in the sample area 110, and the transfer mechanism 210 is configured to place the emergency sample tube in a preset sample tube position 311, where the preset sample tube position 311 may be a sample tube position 311 in a preset area on the dispatching mechanism 310, or may be an idle sample tube position 311 in an area of the dispatching mechanism 310 near one side of the transfer mechanism 210. The scheduling mechanism 310 selects a first step size based on the emergency instruction and drives based on the first step size, wherein the first step size is a step size that the scheduling mechanism 310 moves the sample tube from the preset sample tube position 311 to the processing station 410. The emergency sample tube moves with the drive of the dispatch mechanism 310 such that the emergency sample tube is located within the processing region.

During normal sample injection, the transfer mechanism 210 sequentially places a plurality of sample tubes in the scheduling mechanism 310, and the scheduling mechanism 310 sequentially transmits the sample tubes to the processing area, and at this time, the scheduling mechanism 310 performs transmission according to a first preset direction. When the sample injection module 10 receives the emergency instruction, the transfer mechanism 210 places the emergency sample tube at the preset sample tube position 311, and the scheduling mechanism 310 drives the emergency sample tube into the processing area along the first preset direction or along a second preset direction opposite to the first preset direction. The direction in which the dispatch mechanism 310 drives the emergency sample tubes is related to the position of the processing station 410 and the preset relative position of the sample tube position 311, and is not specifically limited herein.

Wherein the first preset direction and the second preset direction may be a clockwise direction or a counterclockwise direction. For example, the first preset direction is clockwise, and the second preset direction is counterclockwise; or the first preset direction is a counterclockwise direction, and the second preset direction is a clockwise direction.

In this embodiment, the operation instruction is an emergency instruction, the transfer mechanism 210 is configured to place the emergency sample tube at a preset sample tube position 311, and the scheduling mechanism 310 selects a first step size based on the emergency instruction and performs transmission based on the first step size, so that the emergency sample tube is located in the processing area. When an emergency call is required, the dispatching mechanism 310 of the embodiment can directly dispatch the emergency call sample tube based on the emergency call instruction, and the flow is simple, which is beneficial to improving the sampling efficiency.

Optionally, when the data detected by the sample analyzer is abnormal, the sample analyzer needs to re-diagnose the abnormal sample tube so as to ensure the accuracy of the data; at this time, the operation instruction is a review instruction. After receiving the re-diagnosis instruction, the sample injection module 10 obtains the position of the sample tube to be re-diagnosed, and correlates the position of the sample tube to be re-diagnosed with the re-diagnosis instruction, the transfer mechanism 210 stops the current transfer operation, and the scheduling mechanism 310 stops the current scheduling operation, so that the sample analyzer preferentially detects the sample tube to be re-diagnosed.

Specifically, when the sample tube to be re-diagnosed is located on the scheduling mechanism 310, the scheduling mechanism 310 selects a second step length based on the re-diagnosis instruction, and performs transmission based on the second step length, so that the sample tube is located in the processing area. Wherein the second step size is the step size of the scheduling mechanism 310 moving the sample tube to be re-diagnosed from the current sample tube position 311 to the processing station 410.

During routine sample injection, the transfer mechanism 210 sequentially places a plurality of sample tubes in the dispatching mechanism 310, the dispatching mechanism 310 sequentially transfers the sample tubes into the processing area, and at this time, the dispatching mechanism 310 drives in a first preset direction. When the sample injection module 10 receives the review instruction and confirms that a certain sample tube on the dispatching mechanism 310 needs to be reviewed, the dispatching mechanism 310 rotates to retransmit the sample tube into the processing region along a second preset direction opposite to the first preset direction, so that the processing station 410 processes the sample tube to be reviewed located in the processing region preferentially. After the review is finished, the sample injection module 10 continues to execute the detection process which is suspended before.

In this embodiment, the operation instruction is a review instruction, and when the sample tube to be reviewed is located on the scheduling mechanism 310, the scheduling mechanism 310 selects a second step length based on the review instruction, and performs transmission based on the second step length, so that the sample tube is located in the processing area. The scheduling mechanism 310 of the embodiment can directly schedule the sample tube to be re-diagnosed based on the re-diagnosis instruction, and has simple flow and is beneficial to improving the sampling efficiency.

Optionally, the operation instruction is a sample injection instruction, the scheduling mechanism 310 selects a third step size based on the sample injection instruction, and the scheduling mechanism 310 drives based on the third step size so that the sample tube is located in the processing area.

Specifically, during routine sample injection, the sample injection module 10 receives a sample injection instruction, the transfer mechanism 210 sequentially places a plurality of sample tubes on the sample tube positions 311 of the scheduling mechanism 310, and the scheduling mechanism 310 sequentially transfers the sample tubes into the processing region based on the third step size. Wherein the third step corresponds to the distance between two adjacent sample tube bits 311; when the sample tubes in the processing region are processed, the scheduler 310 advances the sample tube position 311 one position in the first preset direction based on the third step transmission once, so that the sample tubes adjacent to the processed sample tubes enter the processing region, and the sample tubes enter the processing station 410 in sequence. At this time, the distance by which the scheduler 310 drives once corresponds to the distance between two adjacent sample tube positions 311.

In this embodiment, the operation instruction is a sample injection instruction, the scheduling mechanism 310 selects a third step length based on the sample injection instruction, and the third step length is a distance between two adjacent sample tube positions 311, and the scheduling mechanism 310 performs transmission based on the third step length, so that the sample tube is located in the processing area. The dispatching mechanism 310 of the embodiment sequentially drives the sample tubes of the sample tube positions 311 into the processing area, no auxiliary parts are needed for positioning, and the structure is simple and easy to realize.

Optionally, the at least one processing station 410 includes a sample sucking position 411 and a recovering position 412, the sample sucking position 411 is used for a sample analyzer to suck samples stored in the sample tubes, the dispatching mechanism 310 drives the sample tubes after sucking the samples into the region of the recovering position 412, and the transferring mechanism 210 transfers the sample tubes on the recovering position 412 to the sample region 110 for recovering. For example, sample tube position 311 on scheduler 310 is provided with a number, and scheduler 310 drives the sample tube in the first position to sample suction position 411 and drives the sample tube in the first position to recovery position 412.

When the dispatching mechanism 310 drives according to the third step length, the driving time of the dispatching mechanism 310 from the sample sucking position 411 to the recovering position 412 is longer than the detection time of the sample analyzer for obtaining the detection data; or, the time for the dispatching mechanism 310 to drive the sample tube at the first position from the sample sucking position 411 to the recovering position 412 is longer than the detection time for the sample analyzer to acquire detection data; or, a preset number of sample tube positions 311 exist between the sample suction position 411 and the recovery position 412, and the time for the scheduling mechanism 310 to drive the sample tubes based on the third step length and pass through the preset number of sample tube positions 311 is longer than the detection time for the sample analyzer to acquire detection data.

Specifically, the sample suction site 411 and the recovery site 412 may be provided at any position of the dispatch mechanism 310. After the sample analyzer performs a sample sucking operation on the sample tube of the sample sucking position 411, the sample analyzer adds a reaction reagent required for detection into the sample to prepare the sample into a reaction liquid suitable for detection by the sample analyzer, and the sample analyzer detects the reaction liquid to obtain detection data. The time for the sample analyzer to acquire the detection data is the time required for the sample analyzer to prepare the reaction liquid and detect the reaction liquid.

After the sample analyzer acquires the detection data, judging whether the detection data of the sample tube is abnormal, and executing a re-diagnosis process on the sample tube by the sample analyzer when the detection data of the sample tube is abnormal; or, in the process of preparing the reaction liquid and detecting, sample loss, pollution and the like occur due to abnormal operation of the sample analyzer, and the sample analyzer executes a re-diagnosis flow on the sample tube; because the transmission time of the dispatching mechanism 310 from the sample sucking position 411 to the recovering position 412 is longer than the detection time of the sample analyzer for acquiring the detection data, when the sample tube needs to be subjected to the re-diagnosis, the sample tube is ensured to be still positioned on the dispatching mechanism 310, so that the sample injection module 10 can conveniently perform the re-diagnosis operation.

In this embodiment, the at least one processing station 410 includes a sample sucking position 411 and a recovering position 412, the sample sucking position 411 is used for a sample analyzer to suck samples stored in a sample tube, the transferring mechanism 210 transfers the sample tube on the recovering position 412 to the sample area 110 for recovering, and when the scheduling mechanism 310 is driven according to the third step, the driving time of the scheduling mechanism 310 from the sample sucking position 411 to the recovering position 412 is longer than the detection time of the sample analyzer to obtain the detection data. By the method of the embodiment, when the re-diagnosis is required, the sample tube is positioned on the dispatching mechanism 310, so that the sample injection module 10 can perform the re-diagnosis operation, and the re-diagnosis efficiency is improved.

Optionally, the sample area 110 is used for placing a sample tube. During sample injection, a user places a plurality of groups of sample racks in the sample area 110, the transfer mechanism 210 transfers sample tubes on the sample racks to the scheduling mechanism 310, the scheduling mechanism 310 moves the sample tubes to the sample absorbing position 411 so that the sample analyzer can absorb samples of the sample tubes, the scheduling mechanism 310 continues to move the sample tubes to the recovery position 412, and the transfer mechanism 210 transfers the sample tubes on the recovery position 412 to the sample racks in the sample area 110, which are injected simultaneously with the sample tubes, so as to complete the sample injection operation.

Because the loading position and the unloading position of the sample tube are the sample frames on the sample area 110, the sample injection module 10 does not need to set a loading area and an unloading area, so that the dispatching process of loading and unloading the sample injection module 10 is reduced, a user can place the sample frames at any position of the sample area 110, and the use experience of the user is improved; and the free area of the sample area 110 can be used as a reloading area or an unloading area, which is beneficial to expanding the sample capacity by expanding the area of the sample area 110.

Optionally, to improve the efficiency of transferring the sample tubes by the transfer mechanism 210, the recycling area of the recycling position 412 is located on a side of the dispatching mechanism 310 close to the transfer mechanism 210, and a conventional sample feeding area for placing the sample tubes by the transfer mechanism 310 on the dispatching mechanism 310 and an emergency sample feeding area for placing the sample tubes by the transfer mechanism 210 under a sample feeding instruction are provided on a side of the dispatching mechanism 310 close to the transfer mechanism 210, where the sample feeding module 10 places the sample tubes by the transfer mechanism 210 under the emergency instruction.

In one embodiment, the location of the regular sample injection area and the emergency sample injection area are fixed, and the emergency sample injection area is located between the regular sample injection area and the recovery location 412. For example, during routine sampling, the dispatching mechanism 310 is driven along a first preset direction, and the side of the dispatching mechanism 310, which is close to the transferring mechanism 210, is sequentially provided with a recycling position 412, an emergency sampling area and a routine sampling area along the first preset direction.

Further, a position detector can be arranged on the emergency sample injection area, and the position detector is used for acquiring whether an emergency sample tube is placed on the emergency sample injection area. Due to the fixed location of the emergency sample injection area, the dispatch mechanism 310 directly drives based on the first step size when the emergency sample tube is placed in the emergency sample injection area. In other embodiments, the location of the emergency sample area is not fixed, the dispatch mechanism 310 obtains location information of the emergency sample tube on the dispatch mechanism 310, and selects the first step size based on the emergency instructions and the location information.

Optionally, the at least one processing station 410 may further comprise an information reading bit for obtaining sample information of the sample tube to correlate the sample information of the sample tube with the detection data of the sample.

Specifically, the information reading bit may be provided with a code scanner, a barcode is adhered on the sample tube, information on the barcode corresponds to personal information of a person to be tested, a detection item and the like, and before the sample analyzer performs a sample sucking operation on the sample tube, the sample analyzer needs to obtain sample information of the sample tube. For example, the transfer mechanism 210 places the sample tube in the dispatch mechanism 310, the dispatch mechanism 310 transfers the sample tube to the information reading station, transfers the sample tube to the sample suction station 411, and transfers the sample tube to the recovery station 412 to recover the sample tube.

In other embodiments, the information reading bit may be disposed at other positions of the sample module 10, for example, the transfer mechanism 210 transfers the sample tube to the information reading bit before the sample tube is placed at the sample tube position 311, and after the scanner of the information reading bit obtains the information of the sample tube, the transfer mechanism 210 places the sample tube at the sample tube position 311.
