Description

Technical Field

[0001] The present invention relates to the technical field of sample analysis, and in particular to a mixing device and a sample analyzer using the mixing device. Background Art

[0002] Blood samples need to be fully mixed before measurement, otherwise the measurement results will have a large deviation. At present, when the analyzer measures peripheral blood samples, it is usually necessary to manually mix the samples by flicking them with your fingers before putting them into the analyzer for testing. However, this mixing method greatly limits the number of sample batch measurements and increases the burden of manual operation, which is extremely inconvenient.

[0003] In the related art, an abutment portion is provided in the cup holder for placing a reaction cup or a test tube, so that after the reaction cup or the test tube is inserted into the cup holder, the abutment portion can make the axis of the reaction cup or the test tube have a fixed angle α or eccentricity d with the axis of the cup holder. Such a setting causes the positioning accuracy to be subject to lateral pressure when the test tube is inserted and taken out, affecting the positioning accuracy and reliability of the cup, and more likely to cause the reaction cup to fail to grasp or insert and fall. At the same time, the angle between the reaction cup and the axis of the cup holder cannot be set too large. If it is set too large, the test tube cannot be inserted into the cup holder, and it is easier to drop the test tube. However, if the angle is set too small, the test tube is more difficult to move and mix in the horizontal plane, and the reaction cup holder is a rigid structure, so the noise is relatively large during mixing.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0051] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0053] In addition, in the present invention, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0054] Blood samples need to be fully mixed before measurement, otherwise the measurement results will have a large deviation. At present, when the analyzer measures peripheral blood samples, it is usually necessary to manually mix the samples by flicking them with your fingers before putting them into the analyzer for testing. However, this mixing method greatly limits the number of sample batch measurements and increases the burden of manual operation, which is extremely inconvenient.

[0055] In the related art, an abutment portion is provided in the cup holder for placing a reaction cup or a test tube, so that after the reaction cup or the test tube is inserted into the cup holder, the abutment portion can make the axis of the reaction cup or the test tube have a fixed angle α or eccentricity d with the axis of the cup holder. Such a setting causes the positioning accuracy to be subject to lateral pressure when the test tube is inserted and taken out, affecting the positioning accuracy and reliability of the cup, and more likely to cause the reaction cup to fail to grasp or insert and fall. At the same time, the angle between the reaction cup and the axis of the cup holder cannot be set too large. If it is set too large, the test tube cannot be inserted into the cup holder, and it is easier to drop the test tube. However, if the angle is set too small, the test tube is more difficult to move and mix in the horizontal plane, and the reaction cup holder is a rigid structure, so the noise is relatively large during mixing.

[0075] In one embodiment, if Figure 4 As shown, a bearing is provided in the mounting hole 12, and the main shaft 221 passes through the bearing and is connected to the eccentric shaft 222. It can be understood that the main shaft 221 is rotatably connected to the base 1 through the bearing.

[0076] In this embodiment, the eccentric shaft 222 of the crankshaft 22 and the driven wheel 213 are located on both sides of the base 1. Optionally, the diameter of the main shaft 221 of the crankshaft 22 is larger than the diameter of the eccentric shaft 222. Of course, in other embodiments, the diameter of the main shaft 221 of the crankshaft 22 may also be less than or equal to the diameter of the eccentric shaft 222, which is not limited here.

[0077] In one embodiment, if Figure 4 As shown, a mounting platform 223 is provided at one end of the main shaft 221 passing through the mounting hole 12, and the eccentric shaft 222 is provided at one end of the mounting platform 223 facing away from the main shaft 221 and located at the edge of the mounting platform 223, so that the axis of the eccentric shaft 222 is parallel to the axis of the crankshaft 22 and does not overlap.

[0078] In this embodiment, the axis of the main shaft 221 is parallel to the axis of the eccentric shaft 222 and does not overlap. Figure 2 , Figure 5 and Figure 6As shown, the distance between the axis of the eccentric shaft 222 and the axis of the crankshaft 22 is d. Optionally, the distance d between the axis of the eccentric shaft 222 and the axis of the crankshaft 22 ranges from 0.1 mm to 2 mm. For example, the distance d is 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm, 1.3 mm, 1.5 mm, 1.8 mm, 2 mm, etc., which is not limited here.

[0079] It can be understood that, in such a configuration, when the driving member 21 drives the main shaft 221 of the crankshaft 22 to rotate, the eccentric shaft 222 of the crankshaft 22 rotates around the axis of the main shaft 221, and at the same time, the axis of the eccentric shaft 222 is parallel to and does not overlap with the axis of the crankshaft 22, so that when the eccentric shaft 222 drives the swing frame 31 to rotate, the swing frame 31 will swing, so that the swing frame 31 drives the container seat 32 to swing. In this embodiment, the reaction container 820 and the container seat 32 have a common theoretical axis. When the container seat 32 drives the reaction container 820 to swing relative to the swing frame 31, the angle between the theoretical axis and the eccentric shaft 222 of the crankshaft 22 is α; in the static state without mixing, the angle α is 0, that is, the reaction container 820 and the container seat 32 are both in a vertical state; when mixing, the angle value is greater than 0.

[0080] At the same time, the problem that the angle between the reaction container 820 and the axis of the container seat 32 cannot be too large is solved; in this way, when not mixed, the reaction container 820 can be inserted into or removed from the accommodating cavity 321 of the container seat 32 in a vertical state, and the reaction container 820 is not easy to fall; and when mixing, a larger swing angle can be used to make it easier for the reagent to move back and forth in the horizontal plane in the reaction container 820 for mixing.

[0081] In this embodiment, when the driving member 21 drives the main shaft 221 of the crankshaft 22 to rotate, the swing frame 31 drives the container seat 32 to rotate around the axis of the main shaft 221. After the swing frame 31 generates a swinging force, the container seat 32 can swing relative to the swing frame 31, thereby improving the mixing effect of the sample liquid in the reaction container 820.

[0082] In one embodiment, the swing frame 31 includes a rotating seat 311 and a support frame 312, wherein the rotating seat 311 is provided with a connecting hole 3111, and the end of the eccentric shaft 222 away from the main shaft 221 is rotated through the connecting hole 3111 through a bearing member, and the support frame 312 is arranged on the rotating seat 311, and the support frame 312 is provided with a swing groove 3123, and the container seat 32 can be swingably arranged in the swing groove 3123.

[0083] In this embodiment, if Figures 1 to 6As shown, the swing frame 31 is connected to the eccentric shaft 222 of the crankshaft 22 through the rotating seat 311. The rotating seat 311 is provided with a connecting hole 3111, and the eccentric shaft 222 is rotatably penetrated through the connecting hole 3111 through a bearing member, so that the eccentric shaft 222 is connected to the rotating seat 311.

[0084] It can be understood that the support frame 312 is disposed on the rotating seat 311, and the container seat 32 is swingably disposed in the swing groove 3123 by providing a swing groove 3123 on the support frame 312. In this embodiment, the container seat 32 is accommodated in the swing groove 3123, and the container seat 32 is rotatably connected or hingedly connected to the groove wall of the swing groove 3123, etc., which is not limited here.

[0085] This arrangement solves the problem that the angle between the reaction container 820 and the container seat 32 is a fixed value and cannot be changed; when the container seat 32 drives the reaction container 820 to swing back and forth relative to the rotating seat 311, the liquid in the reaction container 820 is more likely to be mixed by reciprocating motion in the horizontal direction. At the same time, it also solves the problem that the existing mixing structure has a large noise when mixing with a rigid structure.

[0086] In one embodiment, if Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, a clamping groove 224 is provided at one end of the eccentric shaft 222 away from the main shaft 221, and the driving assembly 2 further comprises a clamping ring 23, which is clamped in the clamping groove 224. It can be understood that by providing the clamping groove 224 on the eccentric shaft 222 and clamping the clamping ring 23 in the clamping groove 224, the clamping ring 23 is limitedly abutted against the bearing member in the connecting hole 3111 of the rotating seat 311, thereby improving the connection stability between the rotating seat 311 and the eccentric shaft 222.

[0087] In one embodiment, the support frame 312 includes a base 3121 and two support arms 3122, wherein the base 3121 is arranged on the rotating seat 311, and the two support arms 3122 are spaced apart on the side of the base 3121 facing away from the rotating seat 311, the two support arms 3122 are arranged opposite to each other, and cooperate with the base 3121 to form a swing groove 3123 and two through openings 3124 connecting the swing groove 3123, each support arm 3122 is provided with an axis hole 3125; the outer wall of the container seat 32 is provided with a rotating shaft 322 corresponding to each axis hole 3125, and the rotating shaft 322 is rotatably passed through the axis hole 3125.

[0088] In this embodiment, if Figure 1 , Figure 3 and Figure 4As shown, the base 3121 of the support frame 312 is fixedly connected to the rotating base 311 and is located on the side wall of the rotating base 311 facing away from the base 1. Optionally, the rotating base 311 is arranged parallel to the base 1. Two support arms 3122 are arranged at intervals and opposite to each other on the base 3121 of the support frame 312, so that the two support arms 3122 cooperate with the base 3121 to form a swing groove 3123 and two through openings 3124 connecting the swing groove 3123.

[0089] It can be understood that the two through openings 3124 of the support frame 312 are located at opposite sides of the swing groove 3123 and are connected to the swing groove 3123 . At this time, the line connecting the two through openings 3124 and the line connecting the two support arms 3122 are arranged vertically.

[0090] In this embodiment, an axial hole 3125 is provided on the support arm 3122, and a rotating shaft 322 is provided on the outer wall of the container seat 32 corresponding to each axial hole 3125. In this way, when the container seat 32 is accommodated in the swing groove 3123, the rotating shaft 322 is rotated to pass through the axial hole 3125, so as to realize the rotational connection between the container seat 32 and the support arm 3122.

[0091] Optionally, the shaft hole 3125 is located at one end of the support arm 3122 away from the base 3121, and the rotation shaft 322 is located at one end of the container seat 32 adjacent to the opening of the accommodating cavity 321. In this way, when the container seat 32 swings relative to the support frame 312 of the swing frame 31, the container seat 32 swings around the rotation shaft 322 in the swing groove 3123. Optionally, during the swinging process of the container seat 32, one end of the container seat 32 away from the rotation shaft 322 can pass through the through opening 3124 and extend out of the swing groove 3123, which is not limited here.

[0092] In one embodiment, the swing frame 31 also includes an anti-collision rod 313, which is arranged on the rotating seat 311 and corresponds to the through opening 3124; wherein, when the container seat 32 swings around the rotating shaft 322, one end of the container seat 32 away from the rotating shaft 322 extends out of the through opening 3124 and abuts against the anti-collision rod 313.

[0093] In this embodiment, if Figures 1 to 7 , Fig. 9 As shown, by setting the anti-collision rod 313, the anti-collision rod 313 is set corresponding to the through hole 3124, so that when the container seat 32 swings, the anti-collision rod 313 is used to limit the swing angle of the container seat 32, thereby preventing the container seat 32 from swinging too much and causing the sample liquid in the reaction container 820 to be spilled.

[0094] Understandable, such as Figure 2 , Figure 5 and Figure 6As shown, when the container seat 32 is stationary, the axis of the container seat 32 coincides with the axis of the eccentric shaft 222 of the crankshaft 22, and when the container seat 32 swings, the axis of the container seat 32 forms an angle α with the axis of the eccentric shaft 222 of the crankshaft 22, and the angle α is greater than 0. Optionally, the angle α is greater than 0 and less than or equal to 45°, for example, the angle α is 5°, 8°, 10°, 13°, 15°, 18°, 20°, 23°, 25°, 28°, 30°, 33°, 35°, 38°, 40°, 43°, 45°, etc., which is not limited here.

[0095] In this embodiment, the distance between the setting position of the anti-collision rod 313 on the rotating seat 311 and the opening 3124 is limited by the swing angle of the container seat 32, that is, when the container seat 32 swings, the angle α formed by the axis of the container seat 32 and the axis of the eccentric shaft 222 of the crankshaft 22 cannot be too large or too small. If the angle α is too large, it will easily cause the sample liquid in the reaction container 820 to be spilled; if the angle α is too small, it will lead to problems such as poor mixing effect of the sample liquid in the reaction container 820.

[0096] It can be understood that the anti-collision rod 313 is provided to limit the amplitude of the swing angle of the container seat 32 during the mixing process; when the mixing speed is large enough, the container seat 32 will swing and be blocked by the anti-collision rod 313.

[0097] In one embodiment, the swing frame 31 further includes an elastic member 314 , one end of the elastic member 314 is connected to the bottom of the container seat 32 , and the other end of the elastic member 314 is connected to the base 3121 or the anti-collision rod 313 .

[0098] In this embodiment, if Figure 5 and Figure 6 As shown, by setting the elastic member 314, one end of the elastic member 314 is connected to the bottom of the container seat 32, and the other end of the elastic member 314 is connected to the base 3121 or the anti-collision rod 313, so that the elastic member 314 can be used to reset the container seat 32 when the container seat 32 swings, and at the same time, it can also prevent the container seat 32 from swinging too much during the swinging process, thereby preventing the sample liquid in the reaction container 820 from being spilled.

[0099] Optionally, the elastic member 314 is a spring, such as a return spring, so that the elastic member 314 can be used to achieve buffering, reduce the vibration of the container seat 32, and thus reduce noise and splashing of liquid in the reaction container 820. Figure 5 As shown, one end of the elastic member 314 is connected to the bottom of the container seat 32, and the other end of the elastic member 314 is connected to the base 3121. In this embodiment, the anti-collision rod 313 may be provided or not provided, which is not limited here. Figure 6As shown, one end of the elastic member 314 is connected to the bottom of the container seat 32, and the other end of the elastic member 314 is connected to the anti-collision rod 313, which is not limited here.

[0100] In this configuration, the elastic member 314 can be used to tighten the container seat 32 and the base 3121 or the anti-collision rod 313, so that the container seat 32 and the reaction container 820 are in the original vertical state in the static state without mixing; in the mixing state, the elastic member 314 and the gravity of the container seat 32 jointly limit the swing angle of the container seat 32. It can be understood that the configuration of the elastic member 314 can also shorten the mixing time and increase the detection speed by increasing the rotation speed of the driving member 21.

[0101] Optionally, the anti-collision rod 313 includes two, and the two anti-collision rods 313 are respectively arranged on opposite sides of the base 3121 and respectively arranged corresponding to the two through openings 3124. The elastic member 314 includes two, and one end of the two elastic members 314 is connected to the bottom of the container seat 32, and the other end of the two elastic members 314 is respectively connected to the two anti-collision rods 313.

[0102] It can be understood that such a configuration can further ensure resetting, and can also prevent the container seat 32 from swinging too much during the swinging process, thereby causing the sample liquid in the reaction container 820 to be spilled.

[0103] In one embodiment, if Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, a reset weight block 323 is provided at the bottom of the container seat 32 , and one end of the elastic member 314 is connected to the reset weight block 323 .

[0104] It can be understood that the setting of the reset weight block 323, on the one hand, facilitates the connection between the elastic member 314 and the container seat 32, and on the other hand, the reset weight block 323 also plays a role in enabling the container seat 32 to quickly and statically reset when the driving member 21 stops working. That is, the reset weight block 323 is an additional weight added in the gravity reset solution, which is used to limit the deflection angle of the container seat 32 and the reaction container 820 when they are mixed, and reset them when they are not mixed.

[0105] In one embodiment, the base 1 is further provided with a slide groove 11, which extends toward the mounting hole 12; the swing frame 31 also includes a guide rod 315 arranged on the rotating seat 311, and one end of the guide rod 315 away from the rotating seat 311 can be slidably extended into the slide groove 11.

[0106] It can be understood that when the driving member 21 drives the crankshaft 22 to drive the rotating seat 311 to rotate, the guide rod 315 moves along the slide slot 11 to make the rotating seat 311 reciprocate along the extending direction of the slide slot 11 .

[0107] In this embodiment, if Figures 1 to 8 As described above, by providing the slide groove 11 on the base 1 and providing the guide rod 315 on the rotating seat 311 of the swing frame 31, the end of the guide rod 315 away from the rotating seat 311 can be slidably extended into the slide groove 11, so that when the driving member 21 drives the crankshaft 22 to drive the rotating seat 311 to rotate, the guide rod 315 moves along the slide groove 11, so that the rotating seat 311 reciprocates along the extension direction of the slide groove 11, thereby further ensuring the swing of the container seat 32. Optionally, a rolling bearing 3151 is provided at one end of the guide rod 315 extending into the slide groove 11, thereby improving the guiding effect.

[0108] It can be understood that the extension direction of the slide groove 11 is consistent with the swing direction of the container seat 32, that is, the extension direction of the slide groove 11 is parallel to or coincides with the line connecting the two openings 3124 on the swing frame 31, which is not limited here. That is, the scheme of the guide rod 315 and the slide groove 11 can be used to prevent the container seat 32 from rotating when rotating around the main shaft 221 of the crankshaft 22, so as to provide reciprocating motion for the guide bearing of the container seat 32 by using the structure of the guide rod 315 and the slide groove 11.

[0109] Of course, if Fig. 9 As shown, the guide rod 315 and the slide groove 11 structure may not be provided. In this way, when the driving member 21 drives the main shaft 221 of the crankshaft 22 to rotate, the eccentric shaft 222 drives the rotating seat 311 to rotate around the main shaft 221, and the rotating seat 311 can rotate around the eccentric shaft 222, thereby ensuring the mixing effect.

[0110] like Figures 1 to 8 As shown, for the solution of setting the guide rod 315 for the swing frame 31, the container seat 32 will swing back and forth left and right, so there are two left and right anti-collision rods 313; Fig. 9 As shown, for the solution in which the swing frame 31 is not provided with the guide rod 315 , the container seat 32 will only swing in the direction away from the main shaft 221 of the crankshaft 22 , so there is only one anti-collision rod 313 .

[0111] It can be understood that for the solution of setting the guide rod 315 for the swing frame 31, when the mixing device 700 is in a stationary and non-mixing state, the container seat 32 will rotate under the rotation of the crankshaft 22 driven by the rotating motor 211; when the rotating baffle 634 triggers the rotating optical coupler 632 and moves a certain distance, the rotating motor 211 stops; the container seat 32 stops at a fixed original position and returns to a stationary vertical state under the action of gravity or a spring, or both.

[0112] When the reaction container 820 is vertically inserted downward into the accommodating cavity 321 of the container seat 32, the cup-moving gripper of the reaction container 820 is separated from the reaction container 820 (the cup-moving gripper of the reaction container 820 can grab or put down the reaction container 820 from the vertical top of the reaction container 820, or can clamp or separate from the reaction container 820 from the side of the reaction container 820. Optionally, when the gripper clamps or separates from the reaction container 820 from the side, if there is a lateral force on the reaction container 820, the entry and exit direction of the gripper should be in the same direction as the swing axis of the container seat 32 to avoid the container seat 32 from having a swing angle that is not in a vertical state when the reaction container 820 is grasped or separated laterally).

[0113] The rotating motor 211 drives the crankshaft 22 to drive the container seat 32 to revolve around the main axis 221 of the crankshaft 22. At this time, the crank-connecting rod slider mechanism formed by the guide rod 315 and the crankshaft 22 in the horizontal plane restricts the container seat 32 from rotating around the eccentric shaft 222 of the crankshaft 22. The container seat 32 can only reciprocate around the horizontal axis of the container seat 32 in the vertical plane under the action of centrifugal force while revolving, so that the sample to be tested in the reaction container 820 simultaneously revolves, reciprocates and swings, and moves up and down, making it easier to mix.

[0114] When the mixing is finished, the container seat 32 returns to its original position and resets to a vertical state, the reaction container 820 is taken away, and the mixing is finished.

[0115] It can be understood that for the solution in which the swing frame 31 is not provided with the guide rod 315, the other steps are the same as the solution in which the swing frame 31 is provided with the guide rod 315; only when the container seat 32 starts to rotate and mix, the container seat 32 will rotate around the eccentric shaft 222 of the crankshaft 22 while revolving around the main shaft 221 of the crankshaft 22; therefore, the container seat 32 will only swing in the direction away from the outside of the main shaft 221 of the crankshaft 22; and no reciprocating swing in the vertical plane will occur. Of course, in order to achieve a good mixing effect, the mixing can be achieved by setting the rotating motor 211 to adopt a forward or reverse rotation mode, which is not limited here.

[0116] For all different reaction cups or test tube reaction containers 820, the above-mentioned swing frame 31 can be used with or without the guide rod 315. For the reset scheme of the container seat 32, the gravity reset scheme of the container seat 32 itself or the addition of a counterweight can be adopted, or the reset scheme of a single spring or a double spring acting together in the vertical plane can be adopted. It can be understood that in the spring reset scheme, the mixing speed of the container seat 32 of the mixing mechanism 100 can be relatively high and noiseless. In the gravity reset scheme, when the speed is low, the container seat 32 will not hit the anti-collision rod 313 and there will be no noise. If the anti-collision rod 313 adopts a harder elastic element, there will be no noise.

[0117] In one embodiment, the lifting assembly 520 includes a lifting motor 521, a synchronous wheel 523 and a synchronous belt 524. The lifting motor 521 is arranged on the substrate 510. The output shaft of the lifting motor 521 is provided with a driving wheel 522. The synchronous wheel 523 is rotatably arranged on the substrate 510 and is spaced and arranged opposite to the driving wheel 522. The synchronous belt 524 is sleeved on the driving wheel 522 and the synchronous wheel 523, and the synchronous belt 524 is fixedly connected to the base 1; wherein the lifting motor 521 drives the driving wheel 522 to rotate, so that the synchronous belt 524 drives the base 1 to rise and fall along the first direction.

[0118] In this embodiment, if Figures 7 to 11 As shown, the lifting motor 521 is fixedly mounted on the base plate 510. For reasonable assembly, the output shaft of the lifting motor 521 can rotatably pass through the base plate 510, and the output shaft of the lifting motor 521 is provided with a driving wheel 522, and the synchronous wheel 523 is rotatably arranged on the base plate 510, so that the synchronous wheel 523 and the driving wheel 522 are spaced and arranged oppositely, and the synchronous belt 524 is sleeved on the driving wheel 522 and the synchronous wheel 523. In this way, when the lifting motor 521 drives the driving wheel 522 to rotate, the synchronous belt 524 drives the synchronous wheel 523 to rotate.

[0119] It can be understood that the base 1 of the mixing mechanism 100 is provided with a fixing member, and the base 1 is fixedly connected to one side of the synchronous belt 524 through the fixing member, so that when the lifting motor 521 drives the driving wheel 522 to rotate forward or reverse, the synchronous belt 524 drives the base 1 to rise and fall. In this embodiment, the synchronous belt 524 is used in conjunction with the synchronous wheel 523 to be used as an idler wheel for tensioning and guiding the synchronous belt 524 and transmitting power. Optionally, the lifting motor 521 can be a stepping motor.

[0120] In one embodiment, if Figures 7 to 11 As shown, the base plate 510 is provided with a slide rail 511 , the slide rail 511 is parallel to and spaced from the synchronous belt 524 , and the base 1 is provided with a slide groove that slidably cooperates with the slide rail 511 .

[0121] It can be understood that by arranging the slide rail 511 on the base plate 510, and arranging the slide groove that slidably cooperates with the slide rail 511 on the base 1, the slide rail 511 is used to provide guidance for the lifting and lowering of the mixing mechanism 100. In this embodiment, the slide rail 511 and the slide groove can adopt a wedge-shaped limiting matching structure or a dovetail limiting matching structure, for example, the slide rail 511 is a wedge-shaped or dovetail-shaped structure, and the shape of the slide groove is adapted to the shape of the slide rail 511, so that the mixing mechanism 100 can achieve limiting matching with the slide rail 511 through the slide groove.

[0122] In one embodiment, the transverse movement assembly 420 includes a transverse movement motor 421, a synchronous pulley and a transverse movement belt 424. The transverse movement motor 421 is arranged on the mounting frame 410. The output shaft of the transverse movement motor 421 is provided with a driving pulley 422. The synchronous pulley is rotatably arranged on the mounting frame 410 and is spaced and arranged opposite to the driving pulley 422. The transverse movement belt 424 is sleeved on the driving pulley 422 and the synchronous pulley, and the transverse movement belt 424 is fixedly connected to the base plate 510; wherein, the transverse movement motor 421 drives the driving pulley 422 to rotate, so that the transverse movement belt 424 drives the base plate 510 to move transversely along the second direction.

[0123] In this embodiment, if Fig.10 and Fig.11 As shown, the transverse motor 421 is fixedly mounted on the mounting frame 410. For reasonable assembly, the output shaft of the transverse motor 421 can rotatably pass through the mounting frame 410, and the output shaft of the transverse motor 421 is provided with a driving pulley 422, and the synchronous pulley is rotatably arranged on the mounting frame 410, so that the synchronous pulley and the driving pulley 422 are spaced and arranged relatively, and the transverse belt 424 is sleeved on the driving pulley 422 and the synchronous pulley, so that when the transverse motor 421 drives the driving pulley 422 to rotate, the transverse belt 424 drives the synchronous pulley to rotate.

[0124] It can be understood that the base plate 510 of the lifting mechanism is provided with a fixing part, and the base plate 510 is fixedly connected to one side of the transverse belt 424 through the fixing part, so that when the transverse motor 421 drives the driving pulley 422 to rotate forward or reverse, the transverse belt 424 drives the base plate 510 to reciprocate along the second direction. In this embodiment, the transverse belt 424 is used in conjunction with the synchronous pulley to be used as an idler wheel for tensioning and guiding the transverse belt 424 and transmitting power. Optionally, the transverse motor 421 can be a stepping motor.

[0125] In one embodiment, if Fig.10 and Fig.11 As shown, the mounting frame 410 is provided with a guide rail 411 , which is parallel to and spaced from the transverse belt 424 , and the base plate 510 is provided with a guide groove which is slidably matched with the guide rail 411 .

[0126] It can be understood that by arranging the guide rail 411 on the mounting frame 410, and arranging the guide groove that slidably cooperates with the guide rail 411 on the base plate 510, the guide rail 411 is used to provide guidance for the lateral movement of the lifting mechanism and the mixing mechanism 100. In this embodiment, the guide rail 411 and the guide groove can adopt a wedge-shaped limiting cooperation structure or a dovetail limiting cooperation structure, for example, the guide rail 411 is a wedge-shaped or dovetail-shaped structure, and the shape of the guide groove is adapted to the shape of the guide rail 411, so that the base plate 510 of the lifting mechanism can achieve limiting cooperation with the guide rail 411 through the guide groove.

[0127] In this embodiment, the mixing device 700 adopts a two-dimensional mixing component solution of horizontal movement and vertical lifting, that is, a transverse movement component 420 is added on the basis of the lifting mechanism driving the mixing mechanism 100 to achieve lifting in the first direction, so that the transverse movement component 420 drives the lifting mechanism and the mixing mechanism 100 as a whole to achieve horizontal movement along the second direction; then the mixing mechanism 100 can be upwardly sleeved on the bottom of the reaction container 820 and then move horizontally, so that the axis of the placement hole of the top reaction container 820 coincides with the main axis 221 of the crankshaft 22, so that the axis of the reaction container 820 can be mixed around the main axis 221 within the cone surface during mixing; and when the reaction container 820 is inserted into and out of the accommodating cavity 321 of the container seat 32, it will return to the vertical state, thereby avoiding failure of the reaction container 820.

[0128] It can be understood that the horizontal and vertical lifting two-dimensional solution can enable the reaction container 820 such as the reaction cup and the test tube to be inserted or removed from the accommodating cavity 321 of the container seat 32 with the eccentricity d=0 and the swing angle α=0 to be inserted or removed in a fixed position state, and its positioning accuracy and guidance are more reliable. When eccentric mixing is required, that is, the eccentricity d>0 and the swing angle α>0, the horizontal lateral movement component 420 can change the size of the eccentricity d and the corresponding swing angle α. Correspondingly, if one-dimensional linear motion is further added on the basis of the horizontal and vertical two-dimensional components, the mixing device 700 becomes a three-dimensional mixing mechanism, which is not limited here.

Of course, the mounting plate 611 can also be detachably mounted on the mounting frame 410 by means of snap connection, plug-in fit, screw connection or pin connection, so as to improve the convenience of disassembly and assembly of the lateral movement detection assembly 610.

[0133] In this embodiment, the transverse optical coupler 612 can be an infrared sensor or an optical coupler sensor. By setting a detection slot 613, when the transverse baffle moves laterally with the substrate 510, the transverse baffle passes through the detection slot 613, so that the transverse optical coupler 612 senses and detects, and feeds back a signal to the transverse motor 421 to control the substrate 510 to move along the second direction of the mounting frame 410. Optionally, the transverse optical coupler 612 is electrically connected to the transverse motor 421, or the transverse optical coupler 612 is electrically connected to the main control system or controller or control circuit of the mixing device 700, which is not limited here. Optionally, the transverse baffle can be a sheet metal piece.

[0138] In this embodiment, the lifting optical coupler 622 can be an infrared sensor or an optical coupler sensor. By setting a detection port 623, when the lifting baffle 624 moves with the base 1 of the mixing mechanism 100, the lifting baffle 624 passes through the detection port 623, so that the lifting optical coupler 622 senses and detects, and feeds back a signal to the lifting motor 521 to control the lifting height of the mixing mechanism 100 along the substrate 510. Optionally, the lifting optical coupler 622 is electrically connected to the lifting motor 521, or the lifting optical coupler 622 is electrically connected to the main control system or controller or control circuit of the mixing device 700, which is not limited here. Optionally, the lifting baffle 624 can be a sheet metal piece.

[0139] In one embodiment, the mixing device 700 also includes a rotation detection component 630, which includes a bracket 631, a rotating optical coupler 632 and a rotating baffle 634. The bracket 631 is disposed on the base 1, the rotating optical coupler 632 is disposed on the bracket 631, the rotating optical coupler 632 is provided with a detection notch 633, one end of the rotating baffle 634 is connected to the driving component 2, and the other end of the rotating baffle 634 extends toward the detection notch 633.

[0140] It can be understood that when the driving member 21 of the mixing mechanism 100 drives the crankshaft 22 to rotate, the crankshaft 22 drives the rotating baffle 634 to pass through the detection notch 633 so that the rotating optical coupler 632 can sense and detect.

[0141] In this embodiment, if Figure 1 , Figure 7 , Fig. 9 and Fig.10 As shown, by setting a rotation detection component 630, the rotation optical coupler 632 of the rotation detection component 630 detects or senses the rotation baffle 634 connected to the crankshaft 22 of the mixing mechanism 100 to control the working state of the rotation motor 211 of the driving member 21. It can be understood that the setting of the rotation detection component 630 can control the rotation of the crankshaft 22 driven by the rotation motor 211.

[0142] It can be understood that the rotation detection component 630 is fixed to the base 1 of the mixing mechanism 100 through the bracket 631. The bracket 631 can be set on the base 1 by welding, bonding or integral molding, which can improve the installation stability of the rotation detection component 630. Of course, the bracket 631 can also be detachably installed on the base 1 by means of snap connection, plug-in fit, screw connection or pin connection, so as to improve the convenience of disassembly and assembly of the rotation detection component 630.

[0143] In this embodiment, the rotating optical coupler 632 can be an infrared sensor or an optical coupler sensor, and the detection notch 633 is set, so that when the rotating baffle 634 rotates with the crankshaft 22, the rotating baffle 634 passes through the detection notch 633, so that the rotating optical coupler 632 senses and detects, and feeds back a signal to the rotating motor 211 to control the rotation of the crankshaft 22 driven by the rotating motor 211. Optionally, the rotating optical coupler 632 is electrically connected to the rotating motor 211, or the rotating optical coupler 632 is electrically connected to the main control system or controller or control circuit of the mixing device 700, which is not limited here.

[0144] like Fig.10 and Fig.11 As shown, the present invention further proposes a sample analyzer 900, which includes a device body and the above-mentioned mixing device 700, and the mixing device 700 is arranged in the device body. The specific structure of the mixing device 700 refers to the above-mentioned embodiment. Since the present sample analyzer adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.

[0145] In this embodiment, the equipment body is provided with a disc 810 and a plurality of reaction containers 820 , the disc 810 is provided with a plurality of mounting ports 811 , each reaction container 820 is detachably arranged at a mounting port 811 , the mixing device 700 is arranged at the equipment body, and the accommodating cavity 321 of the mixing device 700 is opposite to a reaction container 820 .

[0146] It is understandable that the reaction container 820 can be a reaction cup or a test tube. The reaction cup is used to provide a container for the instrument to add samples and reagents, react, mix, and detect. The test tube is a slender tubular bottle used to collect and store samples to be tested, which can be sealed with a cap or used without a cap.

[0147] In the present embodiment, the reaction cup or test tube can be selected as a round tube reaction cup, an inner octagonal round tube reaction cup, a vacuum blood collection tube, a micro vacuum blood collection tube or a square tube reaction cup, etc., which is not limited here. It can be understood that the inner and outer walls of the round tube reaction cup are cylindrical tubular reaction cups, especially the reaction cups used in the field of chemiluminescence. The inner wall of the inner octagonal round tube reaction cup is divided into two sections, the upper section is an inner octagonal round tube, and the lower section is a reaction cup of a cylindrical tube, especially the reaction cup used in the field of coagulation. The vacuum blood collection tube is especially exemplified by the cylindrical vacuum blood collection tube used for blood cells and biochemistry. The micro vacuum blood collection tube is especially exemplified by the micro vacuum blood collection tube used for blood cells, because the amount of samples to be tested is small, and the samples to be tested are not at the bottom of the test tube but in the middle of the test tube. The inner and outer walls of the square tube reaction cup are square or rectangular reaction cups, especially the square cup used in the field of chemiluminescence, which is not limited here.

[0148] The mixing device 700 of the present invention solves the problem in the prior art that when the reaction cup or test tube is inserted downward into the cup holder and descends to the end, it must have a fixed angle α or eccentricity d with the axis of the cup holder. It avoids the positioning accuracy being subjected to lateral pressure when the test tube is inserted and taken out, affecting the positioning accuracy and reliability of the cup, and avoiding the failure of the reaction cup to be grasped or inserted and dropped; it also solves the problem that the angle between the reaction cup and the axis of the cup holder cannot be too large; in this way, when not mixed, the test tube can be inserted or removed from the cup holder in a vertical state, and it is not easy to drop the test tube; and when mixing, it can make the reagent easier to reciprocate in the horizontal plane for mixing with a larger swing angle; it also solves the problem that the angle between the reaction cup and the cup holder is a fixed value and cannot be changed; it makes the liquid in the reaction cup easier to reciprocate in the horizontal direction for mixing when the reaction cup swings back and forth; it also solves the problem that the existing mixing structure is a rigid structure with high noise during mixing.
