[0002] The combination of chemiluminescence immunoassay technology and POCT products has resulted in fully automated POCT chemiluminescence devices. These devices offer the advantages of instant detection and rapid diagnostic results, and have been rapidly and widely adopted in the in vitro diagnostics industry.

[0003] Furthermore, based on fully automated POCT chemiluminescence immunoassay equipment, in order to achieve multi-channel detection, there are already multi-channel fully automated POCT chemiluminescence immunoassay equipment on the market. Moreover, some multi-channel fully automated POCT chemiluminescence immunoassay equipment also has other detection functions. Correspondingly, the equipment is equipped with a movable test tube rack mechanism for holding blood samples.

[0004] Medical staff usually need to manually remove the test tube cap before each test to facilitate sample collection by the equipment, and manually replace the cap after each test to prevent sample leakage. The whole operation is cumbersome, time-consuming and labor-intensive, affecting the testing efficiency of the equipment. Sometimes, the test tube cap may be lost or need to be searched for due to improper placement. Utility Model Content

[0051] Please see Figures 1 to 4 The multi-channel POCT fully automated chemiluminescence immunoassay device 100 of this utility model embodiment includes:

[0052] frame;

[0053] A test tube loading mechanism 20 is movably mounted on a rack. The test tube loading mechanism 20 includes a test tube rack for loading multiple test tubes; and

[0054] A test tube cap clamping device 10 is mounted on the frame and corresponds to the test tube loading mechanism 20. The test tube cap clamping device 10 includes a bracket 11 mounted on the frame, a test tube clamping assembly 12 mounted on the bracket 11, and a test tube cap clamping mechanism 13. The test tube loading mechanism 20 passes through the bracket 11. The test tube clamping assembly 12 is located on the side of the test tube loading mechanism 20 and can clamp or release the test tube from the side. The test tube cap clamping mechanism 13 is located above the test tube loading mechanism and can clamp and remove the test tube cap from the top of the test tube or put the test tube cap back on the top of the test tube.

[0055] In the multi-channel POCT fully automated chemiluminescence immunoassay device 100 of the utility model embodiment, the test tube clamping assembly 12 is located on the side of the test tube loading mechanism and can clamp or release the test tube from the side. The test tube cap clamping mechanism 13 can clamp and remove the test tube cap from the top of the test tube or put the test tube cap back on the top of the test tube. Through the cooperation of the test tube clamping assembly 12 and the test tube cap clamping mechanism 13, the function of removing and putting back the test tube cap can be automatically realized without the manual intervention of medical personnel. The whole operation process is automatic, intelligent, time-saving and labor-saving, improving the detection efficiency of the equipment. Moreover, the test tube cap is clamped in the mechanism, and there will be no problem of improper placement after the test tube cap is removed from the test tube.

[0056] The multi-channel POCT fully automated chemiluminescence device 100 in this embodiment has the relevant structure of the existing multi-channel POCT fully automated chemiluminescence device and can realize the relevant analysis and detection functions. The specific structure and function do not involve the inventive point of this utility model and will not be described in detail here.

[0057] The test tube loading mechanism 20 is used to load the test tube rack and move the test tube rack within the equipment, thereby moving the test tubes. The equipment includes a sampling mechanism that can move left and right and rise and fall relative to the test tube loading mechanism 20. Sampling is performed through the coordinated movement of the sampling mechanism and the test tube loading mechanism 20. The specific structure of the test tube loading mechanism 20 and the sampling mechanism is not related to the inventive point of this utility model and will not be described in detail here. Reference can be made to the structure of existing mechanisms with loading, moving test tube racks, and sampling functions.

[0058] In this embodiment, the test tube cap clamping device 10 (support 11) is detachably mounted on the frame. It can be detachably installed and removed from the frame using fasteners such as screws and rivets, facilitating assembly, disassembly, and replacement, while also providing better stability. Moreover, the test tube cap clamping device 10 can be purchased, installed, and disassembled as an independent device, and can be directly adapted to existing equipment, enhancing the intelligence of the equipment.

[0059] The support 11 can be in the shape of a "door" so that the test tube loading mechanism 20 can pass through it. The test tube clamping assembly 12 can be located at the relative center of the support 11, such as at the leg of the support 11, so that it is located on both sides of the test tube loading mechanism 20. The test tube clamping assembly 12 can move towards the center to clamp the test tubes on the test tube loading mechanism 20 from both sides, and the reverse movement will release the test tubes.

[0060] The test tube cap clamping mechanism 13 may specifically include a lifting part on the support 11 and a clamping part on the lifting part. The clamping part can clamp or release the test tube cap by action, and the lifting part can drive the clamping part to move up and down relative to the test tube by action. When the clamping part clamps the test tube cap, the lifting part drives the clamping part to rise, so that the test tube cap can be removed from the top of the test tube. Afterwards, the lifting part drives the clamping part to fall, and the clamping part releases the test tube cap, so that the test tube cap can be put back on the top of the test tube.

[0061] The gripping and releasing actions of the gripping part can be rotational gripping and releasing, or movement gripping and releasing. For example, the gripping part can include a closed state and an open state. It can be closed by relative rotation to be in a closed state, and opened by opposite rotation to be in an open state, or closed by relative movement to be in a closed state, and opened by opposite movement to be in an open state.

[0062] In this embodiment, as Figure 2 As shown, the clamping part is closed by relative rotation, as... Figure 3 As shown, the gripping part is in the open state by rotating in opposite directions.

[0063] In addition, when placing the test tube cap back on top of the test tube, the lifting mechanism can drive the clamping mechanism to press the test tube cap down slightly, so that the test tube cap can be stably inserted back onto the top of the test tube, ensuring the test tube's airtightness and preventing tipping or sample leakage.

[0064] Please see Figures 2 to 4 Furthermore, the test tube clamping assembly 12 includes:

[0065] Two first driving elements 121 are respectively disposed on the support 11, located on both sides of the test tube loading mechanism 20. Each first driving element 121 includes a first driving shaft 1211 facing the test tube; and

[0066] The clamping part 122 is provided at the end of the first drive shaft 1211. The shape of the part of the clamping part 122 facing the test tube is adapted to the shape of the test tube surface. The first drive shaft 1211 can drive the clamping part 122 to move closer to or away from the test tube, and to contact or separate from the test tube.

[0067] Specifically, the first driving element 121 can be a push-pull electromagnet, cylinder or electric push rod or other driving element that can achieve linear drive. It can be installed on the legs of the bracket 11 and located on both sides of the test tube loading mechanism 20, so that the first driving shaft 1211 faces the test tube, which makes it easier for the clamping part 122 to move closer to or away from the test tube.

[0068] At the start of the test, the two first drive elements 121 operate (e.g., the motor rotates forward), and the two first drive shafts 1211 move towards the test tube, pushing the two clamping parts 122 towards the test tube. Since the shape of the portion of the clamping part 122 facing the test tube matches the shape of the test tube surface (i.e., it is arc-shaped), it can clamp the test tube on both sides, preventing the test tube cap clamping mechanism 13 from pulling out the test tube along with it when clamping the test tube cap. When clamping the test tube is no longer needed, the first drive elements 121 operate again (e.g., the motor rotates in reverse), and the two first drive shafts 1211 move away from the test tube direction, separating the two clamping parts 122 from the test tube, allowing the test tube loading mechanism 20 to move again.

[0069] When the first driving element 121 is a push-pull electromagnet, the first driving shaft 1211 is the push-pull rod of the push-pull electromagnet. At this time, an elastic element (such as a spring) is also sleeved on the push-pull rod. One end of the elastic element can be connected to the end of the push-pull rod near the clamping part 122, and the other end can be connected to the first driving element 121. When the first driving element 121 is energized, causing the first driving shaft 1211 to move towards the test tube, the elastic element will be stretched. Thus, when the first driving element 121 is de-energized, the elastic element can retract, pulling the first driving shaft 1211 back to the first driving element 121, thereby achieving automatic reset.

[0070] Please see Figure 4 Furthermore, the clamping part 122 facing the test tube is provided with a first anti-slip structure 1221.

[0071] For example, the first anti-slip structure 1221 can be a structure such as anti-slip texture, rough surface, groove or protrusion formed by machining the side of the clamping part 122 facing the test tube to increase the friction between the clamping part 122 and the test tube. It can be manufactured by machining the clamping part 122 itself. The first anti-slip structure 1221 can also be a structure such as a silicone pad or rubber pad fixed on this side, which can be disassembled and replaced while increasing the friction.

[0072] exist Figure 4 In the embodiment shown, the first anti-slip structure 1221 consists of multiple anti-slip protrusions arranged in parallel along the length of the clamping part 122, and is integrally formed with the clamping part 122.

[0073] Please see Figures 2 to 5 Furthermore, the test tube cap clamping mechanism 13 includes:

[0074] The lifting drive assembly 131 is mounted on the bracket 11; and

[0075] The test tube cap clamping component 132 is provided on the lifting drive component 131. The lifting drive component 131 can drive the test tube cap clamping component 132 to move up and down relative to the test tube. The test tube cap clamping component 132 can switch between an open state and a closed state to loosen or clamp the test tube cap.

[0076] In this embodiment, the overall lifting control is achieved by the lifting drive assembly 131, and the test tube cap clamping assembly 132 provided on the lifting drive assembly 131 is used to clamp and release the test tube cap. Through the cooperation of the lifting drive assembly 131 and the test tube cap clamping assembly 132, the test tube cap is clamped and separated from the top of the test tube and released back.

[0077] For example, when sampling is required, the test tube cap clamping component 132 is controlled to switch from the open state to the closed state to clamp the test tube cap. Then, the lifting drive component 131 is controlled to drive the test tube cap clamping component 132 to rise relative to the test tube, so that the test tube cap is separated from the test tube, which facilitates the subsequent sampling process. When the sampling is finished, the lifting drive component 131 is controlled to drive the test tube cap clamping component 132 to descend relative to the test tube until the test tube cap contacts the test tube. Then, the test tube cap clamping component 132 is controlled to switch from the closed state to the open state to put the test tube cap back.

[0078] Please see Figures 2 to 6 Furthermore, the lifting drive assembly 131 includes:

[0079] The second drive element 1311 is located at the top of the bracket 11;

[0080] The transmission screw 1312 is connected to the second drive element 1311, and the test tube cap clamping assembly 132 is threadedly connected to the transmission screw 1312.

[0081] The slide rails 1313 are provided on the bracket 11 and are distributed along the height direction of the bracket 11; and

[0082] A slider 1314 is slidably mounted on a slide rail 1313. A test tube cap clamping assembly 132 is mounted on the slider 1314. A second driving element 1311 can drive a transmission screw 1312 to rotate in a first direction or a second direction, thereby causing the test tube cap clamping assembly 132 to move up and down relative to the test tube via the slider 1314.

[0083] Specifically, the second drive element 1311 can be a motor, which is electrically connected to the power supply and controller of the equipment to obtain power supply and be controlled to perform orderly and accurate work. The second drive element 1311 can be mounted on the top of the bracket 11 through a plate suspended from the bracket 11, which facilitates the setting of the transmission screw 1312 and facilitates cooperation with the test tube clamping assembly 132.

[0084] The transmission screw 1312 is threadedly connected to the test tube cap clamping assembly 132 to stably convert the rotational motion of the transmission screw 1312 into the lifting motion of the test tube cap clamping assembly 132. When the second drive element 1311 rotates, it drives the transmission screw 1312 to rotate. Under the guidance of the slide rail 1313 and the action of the transmission screw 1312, the test tube cap clamping assembly 132 lifts and lowers stably and smoothly via the slider 1314. The lifting and lowering of the test tube cap clamping assembly 132 has a highest position and a lowest position. At the lowest position, the test tube cap is clamped by the test tube cap clamping assembly 132 or placed back on top of the test tube.

[0085] The first direction can be counterclockwise, and the second direction can be clockwise. That is, when the second driving element 1311 drives the transmission screw 1312 to rotate counterclockwise, or when the second driving element 1311 rotates in reverse, the transmission screw 1312 drives the test tube cap clamping assembly 132 to rise. When the second driving element 1311 drives the transmission screw 1312 to rotate clockwise, or when the second driving element 1311 rotates forward, the transmission screw 1312 drives the test tube cap clamping assembly 132 to fall.

[0086] Please see Figures 4 to 7 Furthermore, the test tube cap clamping assembly 132 includes:

[0087] The housing 1321 is provided on the lifting drive assembly 131, and the lifting drive assembly 131 can drive the housing 1321 to move up and down relative to the test tube;

[0088] A gripping assembly 1322 is provided at the bottom of the housing 1321. The gripping assembly 1322 can be rotated outward to open or rotated inward to close at the bottom of the housing 1321; and

[0089] A third driving element 1323 is provided in the housing 1321. The third driving element 1323 includes a second driving shaft 13231 that is pulsatorically connected to the gripping sub-assembly 1322. The third driving element 1323 can drive the second driving shaft 13231 to rise and fall, so as to drive the gripping sub-assembly 1322 to rotate inward to close or rotate outward to open, so that the test tube cap gripping assembly 132 is in an open or closed state.

[0090] Specifically, the housing 1321 can be detachably connected to the lifting drive assembly 131 (i.e., the aforementioned slider 1314) via screws, rivets, or other structures, which not only provides better stability but also facilitates installation and disassembly. The bottom of the housing 1321 may be provided with two sets of downwardly extending mounting plates, and the clamping sub-assembly 1322 is rotatably disposed between the two sets of mounting plates.

[0091] Furthermore, the top of the housing 1321 is connected to the lifting drive assembly 131, that is, it is threadedly connected to the aforementioned drive screw 1312. When the drive screw 1312 rotates in the first or second direction, the housing 1321 can be raised or lowered through the thread, which in turn drives the clamping sub-assembly 1322 to be raised or lowered, thereby driving the test tube cap to be raised or lowered, separating it from the test tube or covering the top of the test tube. The drive screw 1312 can penetrate into the internal space of the housing 1321 to ensure that the housing 1321 has a sufficiently high lifting distance.

[0092] The gripping component 1322 opens and closes by rotating. It opens when it rotates outward from the housing 1321 and closes when it rotates inward from the housing 1321. A shaft, rod or other structure can be provided on the housing 1321 to pass through the gripping component 1322 and the housing 1321, so that the gripping component 1322 can be rotatably set on the top of the housing 1321.

[0093] The third driving element 1323 is the power source for the test tube cap clamping assembly 132. It is used to open and close the clamping sub-assembly 1322. The third driving element 1323 is electrically connected to the power supply and controller of the equipment to obtain power supply and be controlled to perform accurate and orderly work.

[0094] The second drive shaft 13231 extends downward to connect with the clamping sub-assembly 1322 at the bottom of the housing 1321. The second drive shaft 13231 can be raised and lowered relative to the housing 1321. It has a maximum upward position and a maximum downward position, which correspond to the fully closed position and the fully open position of the clamping sub-assembly 1322, respectively. When the second drive shaft 13231 is in the maximum upward position, the clamping sub-assembly 1322 is in the fully closed position. When the second drive shaft 13231 is in the maximum downward position, the clamping sub-assembly 1322 is in the fully open position.

[0095] Please see Figures 3 to 5 Furthermore, the second drive shaft 13231 is provided with a limiting part 13232, and the test tube cap clamping assembly 132 also includes an elastic element 1324 sleeved on the second drive shaft 13231. One end of the elastic element 1324 abuts against the third drive element 1323, and the other end abuts against the limiting part 13232. When the clamping sub-assembly 1322 is in the closed state, the elastic element 1324 is in the compressed state.

[0096] In this embodiment, the limiting part 13232 extends circumferentially from the surface of the second drive shaft 13231, is roughly ring-shaped, and is an integral structure with the second drive shaft 13231. The elastic element 1324 can be a spring, which makes full ring contact with the limiting part 13232, thereby better applying the corresponding force to the second drive shaft 13231.

[0097] The elastic element 1324 is used to switch the test tube cap clamping assembly 132 from the closed state to the open state when the power is off. Specifically, when the third driving element 1323 is energized, the second driving shaft 13231 moves upward to the extreme rising position, driving the clamping sub-assembly 1322 to rotate inward and close until it is fully closed, gradually clamping the test tube cap tightly, while the elastic element 1324 is compressed. When the third driving element 1323 is de-energized, the elastic element 1324 automatically extends downward, and the second driving shaft 13231 is pushed downward to the extreme falling position, while the clamping sub-assembly 1322 rotates outward and opens, gradually loosening the test tube cap until it is fully open.

[0098] Furthermore, the third drive element 1323 can be a drive element capable of linear drive, such as a push-pull electromagnet, a cylinder, or an electric actuator.

[0099] In this embodiment, the third driving element 1323 is a push-pull electromagnet, and the second driving shaft 13231 is the push-pull rod of the push-pull electromagnet. After power is cut off, it is pushed by the elastic element 1324 to achieve automatic reset.

[0100] Please see Figures 4 to 7 Furthermore, the gripper assembly 1322 includes:

[0101] The connecting shaft 13221 is located at the top of the second drive shaft 13231; and

[0102] Two grippers 13222 are rotatably disposed at the bottom of the housing 1321. The two grippers 13222 are arranged opposite to each other. The connecting shaft 13221 rotatably passes through the two grippers 13222. The shape of the part of the gripper 13222 facing the test tube cap is adapted to the shape of the surface of the test tube cap.

[0103] When the second drive shaft 13231 drives the connecting shaft 13221 to rise, the connecting shaft 13221 drives the two grippers 13222 to rotate inward and close. When the second drive shaft 13231 drives the connecting shaft 13221 to fall, the connecting shaft 13221 drives the two grippers 13222 to rotate outward and open.

[0104] Specifically, the bottom end of the second drive shaft 13231 may be provided with a through clearance groove, and the connecting shaft 13221 passes through the top end of the second drive shaft 13231 and the two grippers 13222, so that the second drive shaft 13231 can drive the two grippers 13222 to rotate when it moves, and the clearance groove can provide clearance space for the bottom rotation of the grippers 13222, so as to prevent the second drive shaft 13231 from affecting the rotation of the grippers 13222. The grippers 13222 can be rotatably set with the housing 1321 through the pin 13224.

[0105] When the second drive shaft 13231 drives the connecting shaft 13221 to descend within the housing 1321, the connecting shaft 13221 applies a downward force to the two grippers 13222, and the two grippers 13222 rotate outward and open under the constraint of the pin 13224. After the connecting shaft 13221 descends to its maximum descending position, the two grippers 13222 are fully open. When the second drive shaft 13231 drives the connecting shaft 13221 to rise within the housing 1321, or in other words, when the second drive shaft 13231 is pushed upward by the elastic element 1324, the connecting shaft 13221 applies an upward force to the two grippers 13222, and the two grippers 13222 rotate inward and close under the constraint of the pin 13224. After the connecting shaft 13221 rises to its maximum rising position, the two grippers 13222 are fully closed.

[0106] To ensure that the connecting shaft 13221 can pass through the two grippers 13222 and that the two grippers 13222 can face each other, the connecting part between the grippers 13222 and the connecting shaft 13221 can be a design with only half of the grippers, similar to the design of two pliers heads. Only by aligning the connecting parts of the two grippers 13222 can they be combined into a complete connecting part, providing sufficient space for the two grippers 13222 to face each other.

[0107] Alternatively, the connecting parts of the grippers 13222 are two oppositely arranged parts that are not directly connected together. The connecting parts of the two grippers 13222 can be respectively in the shape of an inward step and an outward step. The inward step is located on the inside and the outward step is located on the outside, which is equivalent to the two connecting parts of one gripper 13222 being clamped by the two connecting parts of the other gripper 13222.

[0108] Furthermore, the portion of the gripper 13222 facing the test tube cap is provided with a second anti-slip structure 13223.

[0109] For example, the second anti-slip structure 13223 can be a structure such as anti-slip texture, rough surface, groove, or protrusion formed by machining the side of the gripper 13222 facing the test tube cap, used to increase the friction between the gripper and the test tube cap. It can be manufactured by machining the gripper 13222 itself. The second anti-slip structure 13223 can also be a structure such as a silicone pad or rubber pad fixed on this side, which can be disassembled and replaced while increasing the friction.

[0110] exist Figure 7 In the embodiment shown, the second anti-slip structure 13223 is a groove provided in the gripper 13222, in which the test tube cap can be embedded and make large-area contact, thereby achieving stable gripping.

[0111] Please see Figures 2 to 5 Furthermore, the housing 1321 includes:

[0112] A mounting body 13211 is detachably connected to the lifting drive assembly 131. The front of the mounting body 13211 has an opening communicating with its internal space. A clamping sub-assembly 1322 is located at the bottom of the mounting body 13211, and a third drive element 1323 is located within the mounting body 13211.

[0113] A cover plate 13212 is detachably mounted on the opening. The mounting body 13211 has a support part 13213 that supports the cover plate 13212.

[0114] Specifically, the mounting body 13211 has a front-opening structure with an internal space for mounting the third drive element 1323. This opening covers a large area of ​​the front of the mounting body 13211 to provide a sufficiently large operating space for installing or removing the third drive element 1323 from the front of the mounting body 13211. The cover plate 13212 can be directly engaged with the mounting body 13211, for example, by a snap-fit ​​structure, or by fasteners such as screws or rivets.

[0115] Preferably, the cover plate 13212 can be fixed to the opening with screws, which is more stable and easier to disassemble and install.

[0116] For example, the support portion 13213 can be provided on the inner side wall of the mounting body 13211, such as in the four corners, two opposite side walls, four side walls or the upper side wall, to stably support the cover plate 13212. The support portion 13213 is spaced apart from the opening, and the cover plate 13212 can be embedded in the mounting body 13211, making the appearance of the housing 1321 more flat and regular, and the cover plate 13212 more stable.

[0117] It is worth mentioning that when the support part 13213 is only provided on the upper side wall, the area of ​​the support part 13213 can be relatively large, ensuring that the cover plate 13212 has a sufficiently large support area and ensuring the stability of the cover plate 13212.

[0118] In this embodiment, the workflow of the equipment controlling the test tube loading mechanism 20 and the test tube cap clamping device 10 (i.e., the test tube clamping assembly 12 and the test tube cap clamping mechanism 13 (i.e., the lifting drive assembly 131 and the test tube cap clamping assembly 132)) can be as follows:

[0119] 1. At the start of the test, the test tube cap clamping assembly 132 is in the open state. The device first controls the test tube loading mechanism 20 to move so that the test tube to be sampled is aligned with the test tube clamping assembly 12. Then, the device controls the test tube clamping assembly 12 to work and clamp the test tube. After that, the device controls the lifting drive assembly 131 to work and lower the test tube cap clamping assembly 132 to gradually approach the test tube cap. After the test tube cap clamping assembly 132 has lowered to the lowest position, the device controls it to work and switch from the open state to the closed state to gradually clamp the test tube cap. After the test tube cap clamping assembly 132 has completely clamped the test tube cap, the device controls the lifting drive assembly 131 to work again and raise the test tube cap clamping assembly 132 to the highest position, causing the test tube cap to detach from the test tube. At the same time, the device controls the test tube clamping assembly 12 to release the test tube. Then, the device controls the test tube loading mechanism 20 to work again and move the test tube with the cap removed to the set position. Finally, the device controls the sampling mechanism to take a sample from the test tube with the cap removed.

[0120] 2. After sampling by the sampling mechanism, the test tube loading mechanism 20 is moved to align with the test tube clamping component 12. The lifting drive component 131 is then activated, causing the test tube cap clamping component 132 to descend to its lowest position. The test tube cap clamping component 132 is then activated, switching from a closed to an open state to place the test tube cap back onto the top of the test tube. If other test tubes need to be sampled after the test tube cap clamping component 132 is fully open, the test tube loading mechanism 20 is moved forward one position, aligning the second test tube with the test tube clamping component 12, and the above process is repeated. If sampling is not required, the current state can be maintained, i.e., the test tube cap clamping component 132 remains in its lowest and open position, facilitating direct sampling during the next test and accelerating testing efficiency. Alternatively, the lifting drive mechanism can be activated to raise the test tube cap clamping component 132 to a set position, preventing it from interfering with the operation of other mechanisms.

[0121] It is worth mentioning that if the test tube cap clamping component 132 is already in the lowest position and in the open state when the test begins, then after the test tube clamping component 12 clamps the test tube, it is not necessary to control the lifting drive component 131 to work, and the test tube cap clamping component 132 can be directly controlled to clamp the test tube cap.
