Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a sample scheduling method and a sample injection device. Background Art

[0002] In the field of medical devices, along with the progress of society, medical equipment is also constantly updated and iterated. The detection mode has gradually developed from the initial single-machine detection to multi-machine online detection and assembly line detection. The sample rack has also changed from being tested on only one instrument at the beginning to being tested on different instruments later. For online or assembly lines, there is usually a sampling module. The manufacturer will set the operation strategy of the sample rack in the sampling module, and the sample rack will go to different analyzers for testing according to the operation strategy. However, in actual usage scenarios, there are often situations where emergency sample racks need to urgently produce measurement results. Therefore, the rapid processing of emergency sample racks has become an issue that must be considered for online and assembly line detection.

[0003] In a multi-analyzer connection or production line, emergency sample racks usually need to be tested in different instruments. However, it often happens that after the emergency sample rack has finished testing on the first target instrument, the second target instrument is already full of sample racks, causing the emergency sample rack to have to wait.

[0004] Therefore, the relevant technology has the problem of low sample transportation efficiency and inability to quickly produce results for emergency samples. Summary of the invention

[0005] The present invention provides a sample scheduling method and a sample injection device to solve the problems in the related art that the sample transportation efficiency is low and the emergency sample cannot produce results quickly.

[0006] According to one aspect of the present invention, a sample scheduling method is provided, the sample scheduling method comprising: obtaining test items and target instruments for emergency samples; determining the number of target instruments for emergency samples; if it is determined that the number of target instruments for emergency samples is equal to 1, transporting the emergency samples to the target instruments for testing; if it is determined that the number of target instruments for emergency samples is greater than 1, first obtaining the first target instrument, and transporting the emergency samples to the first target instrument for testing; when the emergency sample enters the current target instrument, looping the following steps: obtaining the next target instrument, and determining whether the next target instrument is allowed to add other samples for testing.

[0007] Furthermore, the step of obtaining the next target instrument includes: obtaining the exit time T1 of the emergency sample at the current target instrument; obtaining the working time T2 of the emergency sample at other target instruments other than the current target instrument; if the exit time T1 ≥ working time T2, then the target instrument that meets the above conditions and is closest to the current target instrument is defined as the next target instrument; if only the exit time T1 < working time T2, then the target instrument with the smallest difference between the exit time T1 and the working time T2 is defined as the next target instrument.

[0008] Furthermore, the step of determining whether to allow the next target instrument to add other samples for testing includes: if the departure time T1>working time T2, then allowing testing of other samples whose transportation target is the next target instrument and whose measurement time is less than or equal to the difference between the departure time T1 and the working time T2; if only the departure time T1≤working time T2, then the next target instrument is not allowed to test other samples.

[0009] Furthermore, if it is determined that the number of target instruments for the emergency sample is greater than 1, the first target instrument is first obtained, and in the step of transporting the emergency sample to the first target instrument for testing, the step of obtaining the first target instrument includes: judging the working status of the target instrument for the emergency sample; if there is an idle target instrument, the idle target instrument closest to the emergency sample is set as the first target instrument; if there is no idle target instrument, the target instrument closest to the emergency sample is set as the first target instrument.

[0010] Furthermore, if it is determined that the number of target instruments for the emergency sample is greater than 1, the first target instrument is first obtained, and in the step of transporting the emergency sample to the first target instrument for testing, the step of obtaining the first target instrument includes: setting the target instrument closest to the emergency sample as the first target instrument.

[0011] Further, the exit time T1 is the total measurement time of all sample racks in the current target instrument; or, the exit time T1 is the sum of the total measurement time of all sample racks in the current target instrument and the movement time of all sample racks; or, the exit time T1 is the sum of the total measurement time of all sample racks in the current target instrument, the movement time of all sample racks and the first time margin.

[0012] Furthermore, the working time T2 is the total measurement time of all sample racks in each other target instrument except the current target instrument; or, the working time T2 is the sum of the total measurement time of all sample racks in each other target instrument except the current target instrument and the movement time of all sample racks; or, the working time T2 is the sum of the total measurement time of all sample racks in each other target instrument except the current target instrument, the movement time of all sample racks and the second time margin.

[0013] According to another aspect of the present invention, a sample injection device is provided, and the sample injection device can implement the sample scheduling method provided above. The sample injection device includes an injection module, a transfer module and a controller. The injection module is used for the injection of other samples and / or emergency samples, and the transfer module can transfer samples between the injection module and the target instrument, wherein the controller is used to: obtain the test items and target instruments of the emergency samples; determine the number of target instruments for the emergency samples; if it is determined that the number of target instruments for the emergency samples is equal to 1, the scheduling transfer module will transport the emergency samples to the target instrument for testing; if it is determined that the number of target instruments for the emergency samples is greater than 1, the first target instrument will be obtained first, and the scheduling transfer module will transport the emergency samples to the first target instrument for testing; when the emergency sample enters the current target instrument, the following steps are executed cyclically: obtain the next target instrument, and determine whether the next target instrument is allowed to add other samples for testing.

[0014] Furthermore, the step of obtaining the next target instrument includes: the controller obtains the exit time T1 of the emergency sample at the current target instrument; the controller obtains the working time T2 of the emergency sample at other target instruments other than the current target instrument; if the exit time T1 ≥ working time T2, the controller defines the target instrument that meets the above conditions and is closest to the current target instrument as the next target instrument; if only the exit time T1 < working time T2, the controller defines the target instrument with the smallest difference between the exit time T1 and the working time T2 as the next target instrument.

[0015] Furthermore, the step of determining whether to allow the next target instrument to add other samples for detection includes: if the departure time T1>working time T2, the controller allows detection of other samples whose transportation target is the next target instrument and whose measurement time is less than or equal to the difference between the departure time T1 and the working time T2; if only the departure time T1≤working time T2, the controller does not allow the next target instrument to detect other samples.

[0016] Applying the technical solution of the present invention, the sample scheduling method first obtains the test items and target instruments of the emergency sample, and determines the number of target instruments of the emergency sample, so that the emergency sample can be scheduled according to the number of target instruments of the emergency sample. Specifically, if it is determined that the number of target instruments of the emergency sample is equal to 1, the emergency sample is transported to the target instrument for testing. If it is determined that the number of target instruments of the emergency sample is greater than 1, the first target instrument is first obtained, and the emergency sample is transported to the first target instrument for testing. When the emergency sample enters the current target instrument, the following steps are executed cyclically: obtain the next target instrument, and determine whether the next target instrument is allowed to add other samples for testing. The above-mentioned sample scheduling method can realize the priority test of the emergency sample and enable the emergency sample to quickly produce results. Moreover, when the number of target instruments of the emergency sample is greater than 1, during the test process, when the emergency sample enters the current target instrument, the following steps are executed cyclically: obtain the next target instrument, and determine whether the next target instrument is allowed to add other samples for testing, so that the target instrument is fully utilized, which can improve the transportation efficiency of the sample.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] like Figures 1 to 3 As shown, the first embodiment of the present invention provides a sample scheduling method, and the sample scheduling method includes:

[0026] Step S100, obtain the test items and target instruments of the emergency samples. When an emergency sample rack enters the buffer area, the controller will obtain the corresponding test items on each sample tube on the emergency sample rack, as well as which analyzers are the target instruments corresponding to these test items, and send this information to the corresponding instrument, calculate the measurement time of the emergency sample rack in the corresponding target instrument, and feed it back to the controller.

[0027] Step S200: determine the number of target instruments for emergency samples, and the controller determines the subsequent scheduling strategy according to the number of target instruments for emergency samples.

[0028] Step S310: If the number of target instruments for emergency samples is determined to be equal to 1, the emergency samples are transported to the target instrument for testing. In other words, the test items can be completed by entering only one analyzer. When there is a vacancy in the analyzer, the emergency sample rack can be directly sent to the corresponding analyzer through the dispatch mechanism.

[0029] Step S320: If it is determined that the number of target instruments for the emergency sample is greater than 1, the first target instrument is first acquired, and the emergency sample is transported to the first target instrument for testing. When the emergency sample enters the current target instrument, the following steps are executed cyclically: the next target instrument is acquired, and it is determined whether the next target instrument is allowed to add other samples for testing.

[0030] By applying the sample scheduling method provided in this embodiment, the test items and target instruments of the emergency samples are first obtained, and the number of target instruments of the emergency samples is determined, so that the emergency samples can be scheduled in a targeted manner according to the number of target instruments of the emergency samples. Specifically, if it is determined that the number of target instruments of the emergency samples is equal to 1, the emergency samples are transported to the target instrument for testing. If it is determined that the number of target instruments of the emergency samples is greater than 1, the first target instrument is first obtained, and the emergency samples are transported to the first target instrument for testing. When the emergency sample enters the current target instrument, the following steps are executed cyclically: the next target instrument is obtained, and it is determined whether the next target instrument is allowed to add other samples for testing. By adopting the above-mentioned sample scheduling method, it is possible to realize the priority testing of emergency samples and enable the emergency samples to produce results quickly. Moreover, when the number of target instruments of the emergency samples is greater than 1, during the test process, when the emergency sample enters the current target instrument, the following steps are executed cyclically: the next target instrument is obtained, and it is determined whether the next target instrument is allowed to add other samples for testing, so that the target instrument is fully utilized, which can improve the transportation efficiency of the samples.

[0031] It should be noted that in step S320, if it is determined that the number of target instruments for the emergency sample is greater than 1, the number of target instruments for the emergency sample greater than 1 here includes the following two situations: the first is that there are multiple target instruments for the emergency sample, and the number of each of the multiple target instruments is 1, in which case step S320 can be directly executed; the second is that there are multiple target instruments of the same type corresponding to the emergency sample, in which case a test item only needs to be completed in one target instrument of the same type, and the remaining target instruments of the same type are not needed, and the emergency sample can go directly to the next test item.

[0032] The analyzer in this embodiment is the target instrument.

[0033] In this embodiment, the current target instrument refers to the target instrument where the emergency sample is currently located. For example, if the emergency sample enters the first target instrument, the first target instrument is the current target instrument, and the second target instrument is the next target instrument.

[0034] It should be noted that in this embodiment, the samples are set on the sample rack, and the emergency sample rack or other sample racks are dispatched for transportation. In addition, the sample dispatching method does not need to be dispatched through the buffer area, and the emergency sample can be queued without the need for additional tracks.

[0035] In this embodiment, the step of obtaining the next target instrument includes: obtaining the exit time T1 of the emergency sample at the current target instrument; obtaining the working time T2 of the emergency sample at other target instruments other than the current target instrument; if the exit time T1≥working time T2, then the target instrument that meets the above conditions and is closest to the current target instrument is defined as the next target instrument; if only the exit time T1<working time T2, then the target instrument with the smallest difference between the exit time T1 and the working time T2 is defined as the next target instrument.

[0036] Taking the first target instrument and the second target instrument as an example, when it is determined that there is a situation where the machine exit time T1 ≥ working time T2, the controller will define the target instrument that is closest to the first target instrument and satisfies the condition of machine exit time T1 ≥ working time T2 as the second target instrument for the emergency sample. This is because the situation of machine exit time T1 ≥ working time T2 indicates that there is already an idle target instrument before the emergency sample comes out of the first target instrument, and the emergency sample can be tested in this target instrument at the first time without waiting. For example, if there is only one target instrument that satisfies the condition of machine exit time T1 ≥ working time T2, this instrument is defined as the second target instrument. If there are multiple target instruments that satisfy the condition of machine exit time T1 ≥ working time T2, the target instrument closest to the first target instrument is defined as the second target instrument.

[0037] Taking the first target instrument and the second target instrument as an example, if it is determined that only the exit time T1 < working time T2, it means that after the emergency sample is tested from the first target instrument, the other target instruments are still busy. At this time, the controller defines the target instrument with the smallest difference between the exit time T1 and the working time T2 as the second target instrument to reduce the waiting time for the emergency sample.

[0038] It should be noted that in the step of obtaining the working time T2 of other target instruments other than the current target instrument for the emergency sample, the target instruments that have completed the test items are not considered in the subsequent cycle steps.

[0039] Moreover, the working time T2 refers to the working time of each of the multiple target instruments. For example, if there are three target instruments in addition to the current target instrument, the working time T2 refers to T21, T22, and T23. The working time T2 is the total time to complete the measurement of the existing samples, starting from the time when the emergency sample enters the current target instrument.

[0040] In this embodiment, the step of determining whether to allow the next target instrument to add other samples for detection includes: if the departure time T1>working time T2 exists, then other samples whose transportation target is the next target instrument and whose measurement time is less than or equal to the difference between the departure time T1 and the working time T2 are allowed to be detected; if only the departure time T1≤working time T2, then the next target instrument is not allowed to detect other samples.

[0041] Taking the first target instrument and the second target instrument as an example, if there is a situation where the departure time T1> the working time T2, the controller allows the dispatching agency to transport other samples whose measurement time is less than or equal to the difference between the departure time T1 and the working time T2 in the second target instrument for testing. The controller allows the dispatching agency to transport other sample racks whose transportation target instrument is the second target instrument for emergency samples and whose measurement time is less than or equal to (T1-T2). This allows the second target instrument to continue to load other sample racks, and also ensures that after the emergency sample rack comes out of the first target instrument, the sample rack inside the second target instrument has been tested, and the emergency sample rack can still be tested in the second target instrument as soon as possible.

[0042] Still taking the first target instrument and the second target instrument as an example, if only the exit time T1 ≤ the working time T2, since the second target instrument is still being tested after the emergency sample rack comes out of the first target instrument, at this time, in order to ensure the testing efficiency of the emergency sample rack, the controller does not allow the scheduling mechanism to transfer the sample rack to the second target instrument, so as to ensure that the emergency sample rack can go to the testing position as soon as possible after other sample racks in the second target instrument have finished testing.

[0043] Through this scheduling method, it can be ensured that the emergency sample rack that needs to undergo multiple tests can be tested in the next target instrument as soon as possible after the current instrument completes the test, reducing the time for transferring the emergency sample rack between different instruments and improving the transmission efficiency of the emergency sample rack.

[0044] In this embodiment, if it is determined that the number of target instruments for the emergency sample is greater than 1, then the first target instrument is first obtained, and in the step of transporting the emergency sample to the first target instrument for testing, the step of obtaining the first target instrument includes: judging the working state of the target instrument for the emergency sample; if there is an idle target instrument, then the idle target instrument closest to the emergency sample is set as the first target instrument; if there is no idle target instrument, then the target instrument closest to the emergency sample is set as the first target instrument. By adopting the above method, the emergency sample can be tested as soon as possible.

[0045] Specifically, the controller first obtains the current status of different target instruments corresponding to the emergency samples. If the instrument can still carry sample racks, it is defined as idle; if it is fully loaded, it is defined as busy.

[0046] In other embodiments, if it is determined that the number of target instruments for the emergency sample is greater than 1, the first target instrument is first acquired, and in the step of transporting the emergency sample to the first target instrument for testing, the step of acquiring the first target instrument includes: defining the target instrument closest to the emergency sample as the first target instrument, thereby simplifying the judgment logic of the first target instrument.

[0047] In this embodiment, the machine exit time T1 is the total measurement time of all sample racks in the current target instrument.

[0048] In other embodiments, the machine exit time T1 can be the sum of the total measurement time of all sample racks in the current target instrument and the movement time of all sample racks, so that the calculation of the machine exit time is more accurate; or the machine exit time T1 can be the sum of the total measurement time of all sample racks in the current target instrument, the movement time of all sample racks and the first time margin, so that redundancy can be provided for the calculation of the machine exit time. The first time margin can be calibrated according to actual conditions.

[0049] In this embodiment, the working time T2 is the total measurement time of all sample racks in each other target instrument except the current target instrument.

[0050] In other embodiments, the working time T2 can be made the sum of the total measurement time of all sample racks in each other target instrument other than the current target instrument and the movement time of all sample racks, so that the calculation of the working time is more accurate; or the working time T2 can be made the sum of the total measurement time of all sample racks in each other target instrument other than the current target instrument, the movement time of all sample racks and the second time margin, so that redundancy can be provided for the calculation of the working time. The second time margin can be calibrated according to actual conditions.

[0051] It should be noted that the sample rack can be a sample rack with only one position for placing a sample test tube, and only one sample test tube is transported at a time, or a sample rack that can hold multiple sample test tubes and can transport multiple sample test tubes at a time. The measurement time of the sample rack corresponding to the target instrument is the sum of the measurement time of each sample tube on the sample rack on the target instrument.

[0052] In this embodiment, the sample scheduling method also includes: obtaining test items and target instruments for other samples. In practice, the doctor will store the sample to be tested in a sample tube after collecting the sample to be tested from the patient. A sample label is affixed to the wall of the sample tube. The content on the label can store the information of the sample tube in the form of a barcode or a QR code, including the items that need to be done on the sample tube. Specifically, the barcode on the sample tube is identified by a barcode scanner, and the information is uploaded to the controller, that is, the analysis and detection system. The analysis system can query the identity information of the patient from whom the sample is derived, as well as the test items of the sample to be tested, through the LIS system (Laboratory Information System).

[0053] Specifically, the controller sends the test items of other samples to the corresponding target instrument and calculates the measurement time of the sample rack in each instrument. After the controller obtains the test items on the sample rack, it can send this part of information to the corresponding analyzer. The analyzer calculates the approximate residence time (i.e., measurement time) of the sample rack in the sampling position in combination with the test items, and returns the information to the controller. Thus, the controller obtains the measurement time of other samples in the corresponding target analyzer, thereby obtaining the measurement time of other samples in the corresponding target analyzer. The controller records the measurement time of the sample and controls the scheduling mechanism to transport the sample to the target instrument. The scheduling mechanism usually allows the scheduling mechanism to transport other sample racks (with other samples) to the corresponding analyzer in the order of entering the buffer area. For other sample racks, the first-in-first-out rule is usually adopted, that is, the sample rack entering the sample area and the sample rack that first arrives at the buffer area has a higher priority. When the instrument corresponding to the sample rack has a vacancy, the sample rack will be transferred to the corresponding analyzer by the scheduling mechanism, ensuring that the sample rack is used early.

[0054] When an emergency sample is received at the emergency position, the priority of the sample rack is raised to the highest level, and steps S100, S200, S310, and S320 are then executed.

[0055] like Figure 2 and Figure 3As shown, in order to facilitate the understanding of the sample scheduling method provided by this embodiment, a specific embodiment is used for explanation below: a sample injection device and an embodiment of splicing two analyzers are provided, the injection module includes an injection area 1, a lateral moving area 2, a buffer area 3, a scheduling area 4, and a track area 5, wherein an emergency injection area 3a may be provided in the buffer area 3, a scheduling mechanism 4a is provided in the scheduling area 4, the scheduling mechanism 4a can move along the Y-axis direction, and an injection track 5a and a first sample output track 5b are provided in the track area 5. Other sample racks (used to place other samples) are injected in the injection area 1, and then changed direction through the lateral moving area 2, and temporarily stored in the buffer area 3 through the scheduling mechanism 4a, and the emergency sample rack (used to place emergency samples) can directly enter the buffer area 3 through the emergency injection area 3a. The sample rack in the cache area 3 can be transferred to the first analyzer 6 through the scheduling mechanism 4a, or it can be transferred to the second analyzer 7 through the track area 5. Similarly, the first analyzer 6 can also transfer the sample rack back to the cache area 3 through the scheduling mechanism 4a, and the second analyzer 7 can transfer the sample rack back to the cache area 3 through the track area 5 and then through the scheduling mechanism 4a.

[0056] Regarding the analyzer, the first analyzer 6 includes a first sample injection channel 6a, a second sample outlet track 6b, and a first sampling position 6c, and the second analyzer 7 includes a second sample injection channel 7a, a sample outlet channel 7b, and a second sampling position 7c. In the first analyzer 6, the first sample injection channel 6a can accommodate multiple sample racks. After the sample rack completes sampling at the sampling position 6c, it can enter the recovery module (not shown in the figure) or go to the buffer area 3 or go to other analyzers through the second sample outlet track 6b. The internal structure of other analyzers is similar.

[0057] First, obtain the time T1 when the emergency sample exits the current target instrument. The time T1 when the emergency sample exits the current target instrument is the time when the emergency sample exits the current target instrument after completing the experiment. For example, in the first analyzer 6, the first injection channel 6a can accommodate up to 3 samples, namely the first sample rack 8a, the second sample rack 8b, and the third sample rack 8c. The first sample rack 8a and the second sample rack 8b are other samples, and the third sample rack 8c is the emergency sample. Then the time T1 when the emergency sample exits the first analyzer 6 is the measurement time of the first sample rack 8a + the measurement time of the second sample rack 8b + the measurement time of the third sample rack 8c.

[0058] Then, the working time T2 of the emergency sample in other target instruments other than the current target instrument is obtained. For example, in the second analyzer 7, the fourth sample rack 8d, the fifth sample rack 8e, and the sixth sample rack 8f are respectively provided, and the three sample racks are all other samples. The working time of the second analyzer 7 is the measurement time of the fourth sample rack 8d + the measurement time of the fifth sample rack 8e + the measurement time of the sixth sample rack 8f.

[0059] According to the machine departure time T1 and the working time T2, the next target instrument is obtained, and it is determined whether the next target instrument is allowed to add other samples for testing.

[0060] It should be noted that although the comparison of the order and time of emergency sample entry in the above example only mentions two instruments, this method can also be applied to three or more instruments. When the emergency sample rack enters the second target instrument, the controller will re-acquire the third target instrument and whether to allow the third target instrument to enter other sample racks based on step S320.

[0061] Embodiment 2 of the present invention provides a sample injection device, which can implement the sample scheduling method provided above. The sample injection device includes an injection module, a transfer module and a controller. The injection module is used for the injection of other samples and / or emergency samples. The transfer module can transfer samples between the injection module and the target instrument, wherein the controller is used to: obtain the test items and target instruments of the emergency samples; determine the number of target instruments for the emergency samples; if it is determined that the number of target instruments for the emergency samples is equal to 1, the scheduling transfer module will transport the emergency samples to the target instrument for testing; if it is determined that the number of target instruments for the emergency samples is greater than 1, the first target instrument will be obtained first, and the scheduling transfer module will transport the emergency samples to the first target instrument for testing; when the emergency sample enters the current target instrument, the following steps are executed cyclically: obtain the next target instrument, and determine whether the next target instrument is allowed to add other samples for testing.

[0062] Therefore, the sample injection device can also first obtain the test items and target instruments of the emergency samples, determine the number of target instruments for the emergency samples, and dispatch the emergency samples in a targeted manner according to the number of target instruments for the emergency samples. Moreover, it can also implement priority testing of emergency samples so that emergency samples can produce results quickly. In addition, when the number of target instruments for emergency samples is greater than 1, during the test process, when the emergency samples are transported to the current target instrument, it is determined whether to use the next target instrument to add other samples for testing, so that the target instrument is fully utilized, which can improve the efficiency of sample transportation.

[0063] In this embodiment, the step of obtaining the next target instrument includes: the controller obtains the exit time T1 of the emergency sample at the current target instrument; the controller obtains the working time T2 of the emergency sample at other target instruments other than the current target instrument; if the exit time T1 ≥ working time T2, the controller defines the target instrument that meets the above conditions and is closest to the current target instrument as the next target instrument; if only the exit time T1 < working time T2, the controller defines the target instrument with the smallest difference between the exit time T1 and the working time T2 as the next target instrument.

[0064] Among them, the step of judging whether to allow the next target instrument to add other samples for detection includes: if there is a departure time T1> working time T2, the controller allows the detection of other samples whose transportation target is the next target instrument and whose measurement time is less than or equal to the difference between the departure time T1 and the working time T2; if only the departure time T1≤working time T2, the controller does not allow the next target instrument to detect other samples.

[0065] The technical effects of the above content can be found in Example 1 and will not be described in detail here.

[0066] Through the sample scheduling method and sample injection device provided in the embodiment, the measurement time of each sample rack in the analyzer is calculated by the host computer (controller). When the emergency sample rack enters the first analyzer, the second analyzer corresponding to the emergency sample rack can only allow other specific sample racks to enter, ensuring that the emergency sample rack can be the first to be tested in the second analyzer after the test in the first analyzer is completed, thereby improving the transmission efficiency of the emergency sample rack without affecting the transportation of other sample racks.

It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0069] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0070] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0071] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0072] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
