Description

Technical Field

[0001] This invention relates to the field of in vitro diagnostic technology, and more specifically, to a sample introduction system and an in vitro diagnostic analyzer. Background Technology

[0002] Currently, in most in vitro diagnostic analyzers such as coagulation analyzers, the sample loading system uses a sample rack to hold sample tubes containing the samples to be tested. The sample loading system uses a barcode reader (standard type) to acquire the sample barcode on the sample tube, enabling automatic or semi-automatic barcode recognition (the sample is manually picked up and placed in the sample rack after scanning the barcode).

[0003] The semi-automatic barcode identification system described in the above sample loading system has the disadvantage of being complex to operate, requiring manual identification of each sample barcode, and thus failing to meet the application requirements of rapid batch sample loading and testing. The automatic barcode identification system described in the above sample loading system suffers from limitations in barcode reader recognition distance. Short-range barcode readers are inexpensive, while long-range barcode readers are expensive. For applications requiring rapid batch sample loading and testing, it is necessary to increase the number of short-range barcode readers or select expensive long-range barcode readers to ensure that the barcode reader can identify the sample barcode on the sample tube in each sample rack during the sequential insertion of multiple rows of sample racks. Due to the high cost of barcode readers, both solutions result in a high overall cost for the sample loading system.

[0004] In addition, in the above-mentioned sample injection system, there are instances where users remove sample holders that have not yet completed the test, causing the test to be interrupted.

[0005] In addition, the matrix-type sample introduction system is not compatible with the automatic sample introduction system that is connected to the side of the in vitro diagnostic analyzer, resulting in poor compatibility of the sample introduction system; the matrix-type sample introduction system is also not compatible with the control requirements for sample introduction and sample addition after the in vitro diagnostic analyzer is connected to the fully automated sample processing system, resulting in poor compatibility of the sample introduction system.

[0006] In summary, how to design a sample injection system that reduces its cost while meeting the requirements for one-time batch loading is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0007] In view of this, the purpose of the present invention is to provide a sample injection system and an in vitro diagnostic analyzer that reduces the cost of the sample injection system while meeting the requirement of one-time batch deployment.

[0027] Optionally, the sample rack locking assembly includes: a stop and a stop driving assembly, wherein the stop driving assembly drives the stop to reciprocate along the X direction so that the stop can abut against at least one sample rack assembly in the sample rack slot to lock the sample rack assembly, and the stop can disengage from at least one sample rack assembly in the sample rack slot to release the sample rack assembly.

[0028] Optionally, the sample rack locking assembly further includes a stop linear guide rail, the stop linear guide rail being parallel to the X-direction, and the stop being slidably disposed on the stop linear guide rail.

[0029] Optionally, the sample introduction system further includes:

[0030] A stop position detector is used to detect whether the stop has moved to the position to release all the sample rack assemblies;

[0031] The sample injection controller, when the stop position detector detects that the stop has moved to the position to release all the sample holder assemblies, controls the stop drive assembly to stop driving the stop to move.

[0032] Optionally, the sample injection system further includes an injection control panel, which is equipped with a sample rack status indicator. The sample rack status indicator is used to indicate the status of the sample rack, including the test status of the sample in the sample rack being tested.

[0033] Optionally, the status of the sample rack may further include: the sample loading completion status when the sample rack reaches a set position in the sample rack slot, and the test completion status when the sample in the sample rack has completed the test.

[0034] Optionally, the sample introduction system further includes:

[0035] A sample rack detector, which corresponds one-to-one with the sample rack slot, and is used to detect whether the sample rack has reached a set position in the sample rack slot;

[0037] Optionally, the sample injection window moving component is used to drive the sample injection window and the information code reader to move synchronously along the X direction.

[0038] Optionally, the sample inlet window moving assembly includes a sample inlet window driving component and a belt drive mechanism; wherein, the belt drive mechanism includes a driving wheel, a driven wheel, and a transmission belt wound around the driving wheel and the driven wheel, the sample inlet window driving component drives the driving wheel to rotate, and the sample inlet window and the information code reader are both fixed to the transmission belt.

[0039] Optionally, the sample injection window moving component further includes a window linear guide rail, which is parallel to the X-direction, and both the sample injection window and the information code reader are slidably disposed on the window linear guide rail.

[0040] Optionally, the sample rack slots are ten, and each sample rack is used to hold ten sample tubes.

[0041] Optionally, the sample injection system further includes a streamlined sample loading station and / or an automated sample injection system loading station, wherein the streamlined sample loading station is used to provide samples to the fully automated sample processing system, and the automated sample injection system loading station is used to provide samples to the automated sample injection system.

[0042] Optionally, the sample loading position of the automated sample processing system is provided with an external automated sample loading guide block and an external automated sample loading limit block; wherein, the external automated sample loading guide block is used to guide the sample transport track module of the fully automated sample processing system to ensure that the sample transport track module transports the sample in a set direction; the external automated sample loading limit block is used to limit the sample transport track module to ensure that the sample transport track module transports the sample to the set position of the sample loading position of the automated sample processing system.

[0043] Optionally, the inlet of the sample loading station of the automated sample loading system and the inlet of the sample loading station of the automated sample loading system are both located on the same side of the sample loading system.

[0044] The in vitro diagnostic analyzer has an installation window on its casing. The installation window is used for the automatic sample loading system to deliver the sample to the sample loading position of the automatic sample loading system, and for the fully automated sample processing system to deliver the sample to the sample loading position of the automated sample loading system.

[0045] Based on the sample injection system provided above, the present invention also provides an in vitro diagnostic analyzer, which includes the sample injection system described in any one of the above claims.

[0046] In the sample loading system provided by this invention, the sample rack base is provided with sample rack slots for accommodating and limiting the sample racks. The inlet end of the sample rack slot has an inlet for the sample rack to enter. There are at least two sample rack slots, which are distributed sequentially along the X direction. Each sample rack slot corresponds to a sample rack. In this way, the sample rack base provides a prerequisite for one-time batch loading, that is, the sample rack base allows one-time batch loading. The sample loading window moving component is used to drive the sample loading window and the information code reader to reciprocate along the X direction so that the sample loading window can open and close the inlet of each sample rack slot, and the information code reader can identify the sample information code of the sample tube in the sample rack that enters each sample rack slot. In this way, during the one-time batch loading process, the information code reader can identify the sample information code of the sample tube in each sample rack. The information code reader is a common type, and one information code reader is sufficient to meet the requirements. There is no need to select an expensive information code reader with long-distance recognition capability, nor is it necessary to select multiple information code readers. This reduces the cost of the information code reader while meeting the one-time batch loading requirement, thereby reducing the cost of the sample loading system. Attached Figure Description

[0066] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0067] The in vitro diagnostic analyzer provided in this embodiment of the invention includes: a sample injection system, a sample dispensing system, a constant temperature system, a testing system, a cleaning system, a reaction cup selection and transfer system, a mixing system, a code reading system, as well as an operating software system and an auxiliary system.

[0068] like Figure 1 As shown, the sample injection system includes a sample injection system 100 and a reagent injection system. The sample injection system 100 is used to implement sample injection, and the reagent injection system is used to implement reagent injection.

[0069] The above-mentioned sample addition system includes a sample addition system 300 and a reagent addition system. The sample addition system 300 can add samples, and the reagent addition system can add reagents.

[0070] The above-mentioned constant temperature system can realize the incubation of samples and the cooling of reagents. The constant temperature system includes a constant temperature base 500 and a heating and cooling component. The heating and cooling component is used to incubate the samples on the constant temperature base 500 and to cool the reagents on the constant temperature base 500.

[0071] The aforementioned testing system enables sample testing and data acquisition. The testing system includes a first testing component 600 and a second testing component 700. The first testing component is used to test the sample against a first detection target and acquire data, while the second testing component is used to test the sample against a second detection target and acquire data.

[0072] The above-described cleaning system rinses the sample dispensing needle. The specific structure of the cleaning system can be selected according to the actual situation, and this embodiment does not limit it.

[0073] The aforementioned reaction cup selection and conveying system ensures that the reaction cups are selected and delivered to their designated positions, and it also features a missing cup alarm function. Specifically, the reaction cup selection and conveying system includes a reaction cup selection and conveying component 400, which is used to select and deliver the reaction cups to their designated positions.

[0074] The above-mentioned mixing system is used to mix the sample and reagent in the reaction vessel; the code reading system is used to read and input information about reagents and cleaning solutions.

[0075] The aforementioned operating software system and auxiliary system are used to implement the human-computer interaction interface and report output functions. It is understood that the operating software system and auxiliary system can be referred to as the computer and printer system, and are selected and configured by the user.

[0076] The type of in vitro diagnostic analyzer should be selected based on the specific circumstances. For example, the in vitro diagnostic analyzer could be a fully automated coagulation analyzer, specifically the UR6000 fully automated coagulation analyzer or other types of fully automated coagulation analyzers. Fully automated coagulation analyzers utilize optical principles to acquire sample data and process data for tests based on coagulation methods, chromogenic substrate methods, and immunoturbidimetric methods, obtaining the test results.

[0077] like Figures 1-8 As shown, the sample injection system 100 includes: an injection window assembly 110, a sample rack base assembly 120, a sample rack lock assembly 130, a sample rack assembly 140, a sample loading station 150, an automatic sample injection system loading station 160, and an injection control panel 170.

[0078] like Figure 7 As shown, the sample holder assembly 140 is used to hold sample tubes. The sample holder assembly 140 includes a sample holder 141 and a bushing 142. The sample holder 141 has a sample tube placement hole 1411, and the bushing 142 is disposed within the sample tube placement hole 1411, serving to clamp the sample tubes. It is understood that the bushing 142 is located between the sample tube placement hole 1411 and the sample tube.

[0079] In some embodiments, the sample rack assembly 140 may be selected to include only the sample rack 141, that is, the sample rack assembly 140 does not include the bushing 142.

[0080] The aforementioned sample tube placement hole 1411 has a sample holder opening 1412 on its circumferential sidewall, which facilitates the placement and clamping of the sample tube. Furthermore, the sample holder opening 1412 also exposes the sample information code on the sample tube, ensuring that the information code reader 111 can recognize the sample information code on the sample tube. It is understood that the sample information code can be a barcode or a QR code, etc., and this embodiment does not limit this.

[0081] There may be one or two sample tube placement holes 1411. In some embodiments, there are ten sample tube placement holes 1411. The sample rack assembly also includes hole position information codes, which are set on the sample rack assembly 140, and the hole position information codes correspond one-to-one with the sample tube placement holes 1411. In this way, each sample tube on the sample rack assembly 140 is marked. For example, the hole position information codes are Arabic numerals and letters. In the insertion direction of the sample rack assembly 140 into the sample rack slot 1218, the hole position information code of the first inserted sample tube placement hole 1411 is "Y01", the hole position information code of the second inserted sample tube placement hole 1411 is "Y02", and so on. This will not be elaborated further.

[0082] Of course, the hole position information code can also be other, such as Arabic numerals or a combination of Arabic numerals and other letters. This embodiment does not limit this.

[0083] The sample holder assembly 140 also includes a status information code, which indicates whether a sample tube is placed in the sample tube placement hole 1411. Each status information code corresponds one-to-one with a sample tube placement hole 1411. In this case, the information code reader 111 of the sample inlet window assembly 110 is also used to identify the status information code. The status information code includes a first status information code and a second status information code. The first status information code indicates that no sample tube is placed in the sample tube placement hole 1411, and the second status information code indicates that a sample tube is placed in the sample tube placement hole 1411. When the information code reader 111 identifies the status information code in the sample tube placement hole 1411 as the first status information code, it indicates that no sample tube is placed in the sample tube placement hole 1411. When the information code reader 111 identifies the status information code in the sample tube placement hole 1411 as the second status information code, it indicates that a sample tube is placed in the sample tube placement hole 1411.

[0084] In some embodiments, the first status information code can be selected as "NO" and the second status information code as "YES". Of course, the first status information code and the second status information code can also be selected as other types, and are not limited to the above description.

[0085] In some embodiments, the sample delivery system may exclude the sample holder assembly 140 and is not limited to the above description.

[0086] like Figure 2 and Figure 4 As shown, the sample rack base assembly 120 includes: a sample inlet base plate 121, and a sample rack bracket 123 fixed to the sample inlet base plate 121 by a support column 122; wherein, the sample rack bracket 123 has a sample rack slot 1218, which is used to accommodate and limit the sample rack assembly 140, that is, the sample rack slot 1218 is used to accommodate and limit the sample rack 141, and there are at least two sample rack slots 1218 distributed sequentially along the X direction, with a one-to-one correspondence between the sample rack slots 1218 and the sample rack assembly 140. It should be noted that the sample inlet base plate 121, the support column 122, and the sample rack bracket 123 can all be referred to as part of the sample rack base. Of course, other structures can be selected for the sample rack base, and it is not limited to the above-described structure.

[0087] To facilitate the formation of the sample rack slot 1218, the sample rack bracket 123 is provided with guide protrusions 1219; in the X direction, two adjacent guide protrusions 1219 form the sample rack slot 1218. In the Y direction, there are at least two guide protrusions 1219; wherein, the Y direction is perpendicular to the X direction, and both the X and Y directions are parallel to the horizontal direction. It should be noted that the Y direction is the length direction of the sample rack assembly 140.

[0088] The lengths of at least two guide protrusions 1219 may be the same or different, depending on the actual situation. Of course, it is also possible to have only one guide protrusion 1219 in the Y direction, and it is not limited to the above description.

[0089] In some embodiments, the sample rack tray 123 has ten sample rack slots 1218, meaning that the sample rack tray 123 can accommodate ten sample rack assemblies 140; each sample rack can hold ten samples, so the sample rack tray 123 can hold one hundred sample tubes at a time, which can meet the application requirements of rapid batch sample loading and testing.

[0090] The sample rack slot 1218 has an inlet at its first end for the sample rack to enter; that is, the first end of the sample rack slot 1218 is the inlet end of the sample rack slot 1218. The operator manually pushes the sample rack into the sample rack slot 1218.

[0091] like Figure 3 As shown, the sample injection window assembly 110 includes: a sample injection window 1119, an information code reader 111, and a sample injection window moving assembly that drives the sample injection window 1119 and the information code reader 111 to reciprocate along the X direction. The information code reader 111 is used to identify the sample information code of each sample tube on the sample holder 210, and the sample injection window 1119 and the information code reader 111 move synchronously.

[0092] The sample introduction window 1119 and the information code reader 111 are both located at the inlet end of the sample rack slot 1218. The sample introduction window moving component drives the sample introduction window 1119 to move along the X direction so that the sample introduction window 1119 can close the inlet of each sample rack slot 1218 and also open the inlet of each sample rack slot 1218.

[0093] When a sample rack assembly 140 needs to be inserted into a sample rack slot 1218, the sample introduction window moving component drives the sample introduction window 1119 and the information code reader 111 to move synchronously, so that the sample introduction window 1119 opens the sample rack slot 1218. The information code reader 111 is located on one side of the sample rack slot 1218 and can identify the sample information code of each sample tube in the sample rack assembly 140 that enters the sample rack slot 1218. It can be understood that during the process of the sample rack assembly 140 entering the sample rack slot 1218, the information code reader 111 identifies the sample information code of each sample tube in the sample rack assembly 140, and the information code reader 111 also identifies the status information code on the sample rack assembly 140. Therefore, during the one-time batch shelving process, the information code reader 111 can identify the sample information code of the sample tube in each sample rack assembly 140. The information code reader 111 is a common type and only one information code reader 111 is needed. There is no need to select an expensive information code reader 111 with long-distance recognition capability, nor is it necessary to select multiple information code readers 111. This reduces the cost of the information code reader 111 while meeting the one-time batch shelving requirement, thereby reducing the cost of the sample loading system 100 while meeting the one-time batch shelving requirement.

[0094] To achieve automatic control, the above-mentioned injection window assembly 110 also includes an injection controller, which is used to control the injection window moving assembly to drive the injection window 1119 and the information code reader 111 to move back and forth.

[0095] In some embodiments, when the sample rack assembly 140 needs to be placed in the sample rack slot 1218, the injection controller controls the injection window moving assembly to drive the injection window 1119 to open the inlet of the sample rack slot 1218; when the sample rack assembly 140 reaches a set position within the sample rack slot 1218, the injection controller controls the injection window moving assembly to drive the injection window 1119 to close the inlet of the sample rack slot 1218.

[0096] In some embodiments, the sample injection controller is also connected to the information code reader 111, and receives the sample information codes identified by the information code reader 111. After the sample holder assembly 140 is inserted into place, the sample injection controller begins to parse all the information codes obtained from the information code reader 111: the sample information codes for wells Y01, Y02, Y03, Y04, Y05, Y06, Y07, Y08, Y09, and Y10. The sample injection controller also sends all the information codes to the in vitro diagnostic analyzer and displays the results in the software interface.

[0097] In some embodiments, such as Figure 4 As shown, to facilitate confirmation of sample rack placement, the sample delivery system 100 further includes a sample rack detector 124, which detects whether the sample rack has reached the designated position within the sample rack slot 1218. It is understood that the sample rack detector 124 corresponds one-to-one with the sample rack slot 1218. The delivery controller is connected to the sample rack detector 124. When the sample rack detector 124 detects that the sample rack assembly 140 has reached the designated position within the sample rack slot 1218, the delivery controller controls the delivery window moving component to drive the delivery window 1119 to close the sample rack slot 1218. This prevents the sample being tested from being moved out of the in vitro diagnostic analyzer due to operator error.

[0098] For ease of detection, the sample rack detector 124 is located at the end of the sample rack slot 1218. It is understood that the end of the sample rack slot 1218 and the inlet end of the sample rack slot 1218 are the two ends of the sample rack slot 1218, respectively. The type of sample rack detector 124 is selected according to the actual situation; this embodiment does not limit this selection.

[0099] For ease of installation, the sample rack base assembly 120 also includes a sample rack detector mounting plate 125, which is disposed on the sample rack bracket 123, and the sample rack detector 124 is disposed on the sample rack detector mounting plate 125.

[0100] In some embodiments, to facilitate the operator's awareness of the designated position of the sample rack assembly 140 inserted into the sample rack slot 1218, the sample rack bracket 123 is provided with a push-in ball plunger 1213. When the sample rack assembly 140 reaches the designated position within the sample rack slot 1218, the push-in ball plunger 1213 is pressed down, allowing the operator to feel the sample rack assembly 140 reaching the designated position within the sample rack slot 1218. This push-in ball plunger 1213 can be a standard type or other types of push-in devices; this embodiment does not limit this.

[0101] In some embodiments, to improve structural compactness, the sample injection base plate 121 is provided with a cleaning fluid support column 1215 and a cleaning tank support column 1210; wherein, the top of the cleaning fluid support column 1215 is provided with a cleaning fluid adapter plate 1214, the cleaning fluid adapter plate 1214 is provided with a cleaning fluid bracket 1212, the cleaning fluid bracket 1212 is used to support the cleaning fluid container storing the cleaning fluid; the cleaning tank support column 1210 is provided with a puncture cleaning tank 1211 and a pipeline fixing plate 129, the pipeline fixing plate 129 is used to fix the pipeline, the pipeline is used to drain the cleaning fluid in the puncture cleaning tank 1211. In some embodiments, to facilitate knowing that the sample rack slot 1218 needs to be placed in the sample rack assembly 140, such as Figure 8As shown, the sample introduction control panel 170 includes sample rack control buttons 172 corresponding to sample rack slots 1218. These control buttons 172 issue commands to insert sample racks 141 into sample rack slots 1218. When a sample rack control button 172 issues such a command, the sample introduction controller controls the sample introduction window movement assembly to open the sample rack slot 1218 corresponding to the control button 172. For example, when an operator clicks a sample rack control button 172, the button issues a command that causes the sample introduction window 1119 to open the sample rack slot 1218 corresponding to the control button 172, and the sample rack base assembly 120 to move into place.

[0102] To improve reliability, the aforementioned sample injection window moving assembly has a motion positioning feedback function. Specifically, when the sample injection window 1119 closes any sample rack slot 1218, the sample injection window moving assembly sends a closing signal indicating that the sample rack slot 1218 is closed; when the sample injection window 1119 opens any sample rack slot 1218, the sample injection window moving assembly sends an opening signal indicating that the sample rack slot 1218 is open; when the sample injection window moving assembly sends a closing signal, the sample injection controller controls the sample injection window moving assembly to stop driving the sample injection window 1119 to move; when the sample injection window moving assembly sends an opening signal, the sample injection controller controls the sample injection window moving assembly to stop driving the sample injection window 1119 to move.

[0103] In some embodiments, the operator inserts the sample holder 210 into the sample holder slot 1218 through the inlet. During the closing process of the sample introduction window 1119 (when the sample introduction window 1119 closes all sample holder slots 1218), operator hand injury is easily caused by operator error. To avoid operator hand injury, if the sample introduction window 1119 encounters external resistance during its movement, the sample introduction window moving component issues an alarm command, and the sample introduction controller further controls the sample introduction window moving component to stop driving the sample introduction window 1119 to move according to the alarm command. In this case, the above-described sample introduction system may also include an introduction alarm, which issues an alarm according to the alarm command if the sample introduction window 1119 encounters external resistance during its movement. This avoids the sample introduction window 1119 pressing on the operator's hand during the closing process, thus preventing operator hand injury and improving safety and reliability.

[0104] If the sample inlet window driving component 113 of the above-mentioned sample inlet window moving component is a motor, the motor is connected to the sample inlet controller. The encoder of the motor obtains whether the current movement is subject to external resistance. If so, the sample inlet controller controls the motor to stop driving.

[0105] In some embodiments, such as Figure 3 As shown, the sample injection window moving assembly includes: a sample injection window driving component 113 and a first belt drive mechanism; wherein, the first belt drive mechanism includes a first driving pulley 1110, a first driven pulley 1114, and a first transmission belt 1115 wound around the first driving pulley 1110 and the first driven pulley 1114, the sample injection window driving component 113 drives the first driving pulley 1110 to rotate, and the sample injection window 1119 and the information code reader 111 are both fixed to the first transmission belt 1115. It can be understood that the first belt drive mechanism can be a synchronous belt drive mechanism.

[0106] To facilitate the installation of the sample injection window 1119 and the information code reader 111, the first conveyor belt 1115 is fixed with a window fixing plate 119, and both the sample injection window 1119 and the information code reader 111 are fixed to the sample injection window mounting plate 119. To facilitate the information code reader 111 in recognizing the sample information code, the information code reader 111 is fixed to the window fixing plate 119 via a connecting plate 117.

[0107] In other embodiments, the first belt drive mechanism described above may also be a sprocket drive mechanism or other drive mechanism, and is not limited to a belt drive mechanism.

[0108] In some embodiments, to improve the movement stability of the sample introduction window 1119 and the information code reader 111, the sample introduction window assembly further includes a window linear guide rail 115. The window linear guide rail 115 is parallel to the X-direction, and both the sample introduction window 1119 and the information code reader 111 are slidably mounted on the window linear guide rail 115. To facilitate the installation of the sample introduction window 1119 and the information code reader 111, the window linear guide rail 115 is provided with a slider. The slider is slidably mounted on the window linear guide rail 115, and both the sample introduction window 1119 and the information code reader 111 are fixed to the slider. The sample introduction window 1119 and the information code reader 111 can be fixed to the same slider or to different sliders, depending on the actual situation.

[0109] In other embodiments, the sample inlet window 1119 and the information code reader 111 can be guided by other guiding structures, and are not limited to linear guide rails.

[0110] To facilitate the installation of the window linear guide 115 and the sample injection window moving assembly, the sample injection window assembly 110 also includes a sample injection window mounting plate 116, on which both the window linear guide 115 and the sample injection window moving assembly are mounted.

[0111] When the sample inlet window moving assembly includes a sample inlet window driving component 113 and a first belt drive mechanism, the first driving wheel 1110 and the first driven wheel 1114 are rotatably mounted on the sample inlet window mounting plate 116. The first driven wheel 1114 is fixed to the first driven shaft 1112. The first driven shaft 1112 is rotatably mounted on the sample inlet window mounting plate 116 via the first bearing 1113. In the axial direction of the first driven shaft 1112, the first driven shaft 1112 is relatively fixed to the sample inlet window mounting plate 116 via the first retaining ring 1116.

[0112] The aforementioned code reader 111 needs to output the sample information code it recognizes to the sample injection controller via a cable. To ensure the movement of the code reader 111, the cable also needs to move back and forth. To facilitate cable movement and ensure cable stability, the sample injection window assembly 110 further includes a cable chain 1118. One end of the cable chain 1118 is located on the code reader 111, and the other end is located on the sample injection window mounting plate 116. The cable chain 1118 is used to accommodate the cable connected to the code reader 111.

[0113] To facilitate the installation of the cable chain 1118, the sample inlet window mounting plate 116 is provided with a cable chain support plate 1117, and the other end of the cable chain 1118 is provided on the cable chain support plate 1117.

[0114] To limit the information code reader 111 and the sample injection window 1119 from exceeding a set position, the sample injection window assembly 110 further includes a sample injection window position detector 112. This detector 112 detects whether the sample injection window 1119 has reached the closed position, which is the position where the sample injection window 1119 closes all sample holder slots 1218. If the sample injection window position detector 112 detects that the sample injection window 1119 has reached the closed position, the sample injection controller controls the sample injection window moving assembly to stop moving the sample injection window 1119.

[0115] In some embodiments, the sample inlet window positioning detector 112 is a slot-type photoelectric sensor. The sample inlet window assembly 110 further includes a window positioning detector baffle 1111. The window positioning detector baffle 1111 moves synchronously with the sample inlet window 1119. The window positioning detector baffle 1111 can be inserted into the slot of the slot-type photoelectric sensor to isolate the receiver and transmitter of the slot-type photoelectric sensor.

[0116] To facilitate the installation of the injection window position detector 112, the injection window position detector 112 is disposed on the injection window mounting plate 116. For example, the injection window mounting plate 116 is provided with a position detector mounting plate 114, and the injection window position detector 112 is disposed on the position detector mounting plate 114.

[0117] To facilitate the installation of the window positioning detector baffle 1111, the window positioning detector baffle 1111 and the first conveyor belt pressure plate 118 clamp the first conveyor belt 1115, and the aforementioned window fixing plate 119 is fixed to the window positioning detector baffle 1111.

[0118] like Figure 5 and Figure 6 As shown, the sample rack locking assembly 130 is used to lock the sample rack assembly 140 to be tested in the sample rack slot and to release the sample rack assembly 140 after the test is completed. It can be understood that the sample rack locking assembly 130 is used to lock and release the sample rack assembly 140 located at a set position in the sample rack slot 1218.

[0119] Before the sample rack assembly 140 completes the test, the sample rack locking assembly 130 locks the sample rack assembly 140; after the sample rack assembly 140 completes the test, the sample rack assembly 130 unlocks to release the completed sample rack assembly 140. In this way, the sample rack assembly 140 cannot be removed during testing, preventing it from being arbitrarily removed and thus avoiding interruption of the in vitro diagnostic analyzer test due to accidental operation.

[0120] In some embodiments, the sample rack locking assembly 130 includes a stop 136 and a stop drive assembly that drives the stop 136 to reciprocate along the X direction; wherein the stop 136 is capable of abutting against at least one sample rack assembly 140 in a sample rack slot 1218 to lock the sample rack assembly 140, and the stop 136 is also capable of being displaced from at least one sample rack assembly 140 in a sample rack slot 1218 to release the sample rack assembly 140. It is understood that displacement of the stop 136 and the sample rack assembly 140 means that the stop 136 and the sample rack assembly 140 are no longer in contact.

[0121] On the one hand, the stop 136 can only abut against one sample rack assembly 140 in one sample rack slot 1218 to lock one sample rack assembly 140; on the other hand, the stop 136 can abut against two or more sample rack assemblies 140 in two or more sample rack slots 1218 to lock two or more sample rack assemblies 140.

[0122] In other embodiments, the stop 136 may also lock the sample rack assembly 140 in other ways, such as by using other detachable connection structures such as snap-fit ​​or magnetic connection to connect with the sample rack assembly 140 to lock the sample rack assembly 140.

[0123] The aforementioned stop drive assembly is used to drive the stop 136 to lock the sample rack assembly 140 and to unlock the sample rack assembly 140. It is understood that the stop drive assembly is used to drive the stop 136 to a position abutting against at least one sample rack assembly 140 in the sample rack slot 1218 to lock the sample rack assembly 140, and also to drive the stop 136 to a position offset from at least one sample rack assembly 140 in the sample rack slot 1218 to unlock the sample rack assembly 140.

[0124] To ensure that the stop 136 moves along the X direction, the sample rack locking assembly 130 includes a stop base plate 131 and a stop linear guide rail 135 disposed on the stop base plate 131; wherein, the length direction of the stop linear guide rail 135 is the X direction, and the stop 136 and the stop linear guide rail 135 are in sliding engagement.

[0125] In order to ensure that the stop 136 moves to the position to unlock all sample rack assemblies 140, the sample rack locking assembly 130 further includes a stop position detector 132, which is used to detect whether the stop 136 has moved to the position to unlock all sample rack assemblies 140.

[0126] When the stop position detector 132 detects that the stop 136 has moved to the position where all sample holder assemblies 140 are unlocked, the above-mentioned sample injection controller is used to control the stop drive assembly to stop driving the stop 136 to move.

[0127] To facilitate the installation of the stop position detector 132, the sample rack locking assembly 130 also includes a stop position detector mounting plate 133 fixed to the stop base plate 131.

[0128] In some embodiments, the stop drive assembly includes a stop drive component 134 and a second belt drive mechanism; wherein the second belt drive mechanism includes a second drive pulley 1314, a second driven pulley 1311, and a second transmission belt 1312 wound around the second drive pulley 1314 and the second driven pulley 1311, the stop drive component 134 drives the second drive pulley 1314 to rotate, and the stop 136 is fixed to the second transmission belt 1312. It is understood that the second belt drive mechanism may be a synchronous belt drive mechanism.

[0129] For ease of installation, the sample rack locking assembly 130 includes a stop base plate 131, a second driving wheel 1314 and a second driven wheel 1311 rotatably mounted on the stop base plate 131. The second driven wheel 1311 is fixed to a second driven shaft 139, which is rotatably mounted on the stop base plate 131 via a second bearing 1310. The second driven shaft 139 is axially fixed to the stop base plate 131 via a second retaining ring 1313. For easier installation of the second driven shaft 139, a second driven shaft fixing block 138 is fixed to the stop base plate 131. The second driven shaft 139 passes through the second driven shaft fixing block 138. In this configuration, the second driven shaft 139 is axially fixed to the second driven shaft 139 via the second retaining ring 1313 and the second driven shaft fixing block 138.

[0130] To facilitate the fixing of the stop 136, the stop 136 is mounted on the stop fixing plate 137, and the stop fixing plate 137 is fixed to the second conveyor belt 1312.

[0131] In some embodiments, the stop position detector 132 is a slot-type photoelectric sensor. The sample rack locking assembly 130 further includes a stop position detector baffle 1316, which moves synchronously with the stop 136. The stop position detector baffle 1316 can be inserted into the slot of the slot-type photoelectric sensor to isolate the receiver and transmitter of the slot-type photoelectric sensor.

[0132] To facilitate the installation of the stop position detector baffle 1316, the stop position detector baffle 1316 and the second conveyor belt pressure plate 1315 clamp the second conveyor belt 1312, and the aforementioned baffle 136 is fixed to the stop position detector baffle 1316. It can be understood that the stop fixing plate 137 is fixed to the stop position detector baffle 1316.

[0133] To improve structural compactness, the aforementioned stop 136 and the second conveyor belt 1312 are both located on one side of the stop base plate 131, the stop position detector 132 and the stop drive component 134 are both located on the other side of the stop base plate 131, and the stop position detector baffle 1316 penetrates through the stop base plate 131.

[0134] In some embodiments, when the coagulation analyzer starts testing, the sample rack assembly 140 enters the sample rack slot 1218. After the sample rack assembly 140 reaches the set position, the sample rack locking assembly 130 locks the sample rack assembly 140. After the sample rack is filled, the sample rack locking assembly 130 unlocks, and the sample rack assembly 140 can be removed.

[0135] In other embodiments, when the sample rack detector 124 detects that the sample rack 140 has reached a set position in the sample rack slot 1218, the sample injection controller controls the sample rack locking assembly 130 to lock the sample rack assembly 140 in the sample rack slot 1218; when the sample has been added to the sample rack slot 1218, the sample injection controller controls the sample rack locking assembly 130 to release the sample rack assembly 140 in the sample rack slot 1218.

[0136] like Figure 8 As shown, the sample loading control panel 170 also includes a sample rack status indicator 171, which indicates the status of the sample rack assembly 140. The sample rack status indicator 171 corresponds one-to-one with the sample rack slot 1218. The statuses include sample loading complete, testing, and testing complete. For example, the sample rack status indicator 171 is a status indicator light. A blue status indicator light indicates that the sample rack is in the sample loading complete state, meaning the sample rack has reached the set position within the sample rack slot 1218; a flashing yellow status indicator light indicates that the sample rack assembly 140 is in the testing state, meaning the sample within the sample rack assembly 140 is being tested; and a green status indicator light indicates that the sample rack assembly 140 is in the testing complete state, meaning the sample within the sample rack assembly 140 has completed the test.

[0137] In practice, the stop drive component controls the position of the stop 136 to lock the sample rack component 140. After the test is completed, the sample rack lock component 130 unlocks the current sample rack component 140, and the sample rack status indicator 171 corresponding to the sample rack component 140 indicates that the current sample rack component 140 has completed the test.

[0138] In some embodiments, when the sample rack detector 124 detects that the sample rack assembly 140 has reached a set position within the sample rack slot 1218, the sample introduction controller controls the sample rack status indicator 171 to indicate a sample introduction completion status; when the sample in the sample rack assembly 140 has completed testing and the sample rack lock assembly 130 unlocks the current sample rack assembly 140, the sample introduction controller controls the sample rack status indicator 171 to indicate a test completion status; when the sample in the sample rack assembly 140 is under testing and the sample rack lock assembly 130 locks the current sample rack assembly 140, the sample introduction controller controls the sample rack status indicator 171 to indicate a test status.

[0139] like Figure 1 and Figure 9As shown, the sample loading station 150 of the above-mentioned automated sample processing system is used to provide samples to the fully automated sample processing system. The sample transfer track module of the fully automated sample processing system is used to transfer the samples to the sample loading station 150 of the automated sample processing system. In this way, the sample loading system 100 can be connected to a fully automated sample processing system, improving the compatibility of the sample loading system 100.

[0140] In the in vitro diagnostic analyzer, the sample loading system 300 is used to pick up and load samples at the automated sample loading station 150.

[0141] The aforementioned fully automated sample processing system has functions such as batch sample loading, centrifugation, capping, and storage. The specific structure of the fully automated sample processing system can be selected according to the actual situation, and this embodiment limits it accordingly.

[0142] In some embodiments, such as Figure 4 As shown, the sample loading position 150 of the automated sample processing system is located on the sample inlet base plate 121. The sample inlet base plate 121 is provided with an external automated sample loading guide block 1217 and an external automated sample loading limit block 1216. The external automated sample loading guide block 1217 is used to guide the sample transfer track module of the fully automated sample processing system to ensure that the sample transfer track module transfers the sample in a set direction. The external automated sample loading limit block 1216 is used to limit the sample transfer track module to ensure that the sample transfer track module transfers the sample to the set position of the sample loading position 150 of the automated sample processing system.

[0143] Understandably, once the sample transfer track module of the fully automated sample processing system reaches the position where it abuts against the external flow line limit block 1216, it indicates that the sample transfer track module has transferred the sample to the set position of the flow line sample loading position 150, and the sample transfer track module stops transferring. The aforementioned external flow line guide block 1217 and external flow line limit block 1216 are located at the flow line sample loading position 150.

[0144] The specific structure and shape of the external assembly line guide block 1217 and the external assembly line limit block 1216 can be selected according to the actual situation, and this embodiment does not limit them.

[0145] In some embodiments, when the sample loading system 100 of the in vitro diagnostic analyzer is connected to a fully automated sample processing system, the sample loading control process is as follows:

[0146] The sample transfer track module of the fully automated sample processing system transports the sample to the sample loading station 150 on the automated sample processing line. The fully automated sample processing system is used to feed back the information that the sample has arrived at the sample loading station 150 to the in vitro diagnostic analyzer. The in vitro diagnostic analyzer obtains the test items of the sample from the hospital's LIS (Laboratory Information System). The sample loading system 300 aspirates the sample from the sample loading station 150 on the automated sample processing line. After the aspiration is completed, the fully automated sample processing system is used to remove the sample from the sample loading station 150 on the automated sample processing line from the in vitro diagnostic analyzer.

[0147] like Figure 1 and Figure 10 As shown, the sample loading station 160 of the aforementioned automated sample loading system is used to supply samples to the automated sample loading system. It is understood that the drive module of the automated sample loading system is used to transport the sample to the sample loading station 160. In this way, the aforementioned sample loading system 100 can be connected to an external automated sample loading system, improving the compatibility of the sample loading system 100.

[0148] In the in vitro diagnostic analyzer, the sample loading system 300 is used to retrieve and load samples from the sample loading position 160 of the automatic sample loading system. It should be noted that the sample loading system 300 is also used to retrieve samples from the sampling position on the sample holder base assembly 120.

[0149] The aforementioned automated sample loading system allows for the simultaneous loading of large quantities of samples onto racks and is easy to operate. The specific structure of the automated sample loading system can be selected based on actual circumstances; this embodiment provides a limitation in this regard.

[0150] In some embodiments, when the sample introduction system 100 of the in vitro diagnostic analyzer is connected to an external automatic sample introduction system, the sample addition control process is as follows:

[0151] The automated sample loading system transports the sample rack containing the sample tubes to the sample loading position 160. The automated sample loading system is used to feed back the information that the sample has arrived at the sample loading position 160 to the in vitro diagnostic analyzer. The in vitro diagnostic analyzer obtains the test items of the sample on the sample rack from the hospital's LIS (Laboratory Information System). The sample loading system 300 aspirates the sample from the sample loading position 160. After the aspiration is completed, the automated sample loading system is used to remove the sample from the in vitro diagnostic analyzer from the sample loading position 160.

[0152] like Figure 1 , Figure 9 and Figure 10As shown, the automated sample loading system delivers samples from one side of the sample loading system to the sample loading station 160, and the fully automated sample processing system delivers samples from one side of the sample loading system to the automated sample loading station 150. To simplify the structure, the automated sample loading system and the fully automated sample processing system deliver samples to the corresponding loading stations from the same side of the sample loading system; that is, the inlet of the automated sample loading station 160 and the inlet of the automated sample loading station 150 are both located on the same side of the sample loading system 100.

[0153] It is understandable that the inlet of sample loading position 160 in the automated sample loading system is used for sample entry, and the inlet of sample loading position 150 in the automated sample loading system is also used for sample entry.

[0154] In some embodiments, the automated sample loading system delivers samples from the side of the sample loading system 100 away from the sample dispensing system 300 to the automated sample loading system dispensing position 160, and the fully automated sample processing system delivers samples from the side of the sample loading system 100 away from the sample dispensing system 300 to the automated sample dispensing position 150. For example... Figure 1 , Figure 9 and Figure 10 As shown, the side of the sample injection system 100 that is far from the sample addition system 300 is the left side of the sample injection system 100.

[0155] To facilitate connection to external automated sample loading systems and fully automated sample processing systems, the casing of the aforementioned in vitro diagnostic analyzer is provided with a mounting window. This mounting window allows the automated sample loading system to deliver samples to the sample loading station 160, and the fully automated sample processing system to deliver samples to the automated sample loading station 150. In some embodiments, the mounting window is located on the side of the sample loading system 100 away from the sample loading system 300.

[0156] The specific locations of the sample loading positions 150 and 160 of the automated sample loading system are designed according to actual conditions, and this embodiment does not limit them.

[0157] The aforementioned housing mainly includes a base 200 and a housing body disposed on the base 200, with the aforementioned mounting window disposed on the housing body.

[0158] As mentioned above, the sample injection control panel 170 includes a sample rack status indicator 171 and a sample rack control button 172. The sample injection control panel 170 is a human-computer interaction interface. Users can perform sample injection operations through the sample rack control button 172 and indicate the status of the sample rack through the sample rack status indicator 171.

[0159] In some embodiments, when both the stopper drive component 131 and the sample injection window drive component 113 are motors, the sample injection controller includes a motor drive circuit board 127. This motor drive circuit board 127 includes a first drive circuit board and a second drive circuit board. The first drive circuit board controls the sample injection window drive component 113, and the second drive circuit board controls the stopper drive component 131. In this case, the motor drive circuit board 127 is connected to a power supply, detectors (sample injection window position detector 112, sample holder detector 124, stopper position detector 132, sample holder status indicator 171), and an information code reader 111 via a power communication adapter circuit board 128.

[0160] For the specific control methods of the first and second drive circuit boards, please refer to the previous description; they will not be repeated here.

[0161] To improve structural compactness, the sample injection base plate 121 is provided with a motor drive circuit board fixing plate 126, and the single motor drive circuit board 127 and the power communication conversion circuit board 128 are both located on the single motor drive circuit board fixing plate 126.

[0162] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
