Specific implementation manners

[0032] The core of this application is to disclose a magnetic separation device to improve the efficiency and effect of the magnetic separation and purification process of biological samples.

[0033] To enable those skilled in the art to better understand the solution of this application, the embodiments of this application will be described below with reference to the accompanying drawings. In addition, the embodiments shown below do not impose any limitation on the inventive content recorded in the claims. Moreover, all the contents of the configurations shown in the following embodiments are not limited to what is necessary for the solution of the invention recorded in the claims.

[0034] As Figure 1 、 Figure 2 、 Figure 3 That is Figure 9 As shown, the present invention provides a magnetic separation device, which mainly includes a base 10, a separation component 20 and a driving component. Among them, the base 10 is the main load-bearing component of the magnetic separation device, and it can be provided with a bottom plate with a relatively large area to provide sufficient planar operation space for the magnetic separation device.

[0035] A plurality of placement stations 110 are provided on the base 10, and a solution cylinder 120 is provided on each placement station 110. The solution cylinder 120 is used to accommodate the solution to be separated, that is, multiple groups of solutions to be separated can be set on a single base 10 at the same time, rather than operating a single group of solutions independently.

[0036] The separation assembly 20 includes a carrier plate 210 and a plurality of magnetic rods 220 fixedly disposed on one side of the carrier plate 210. The magnetic rods 220 are used to magnetically separate the target in the solution. It should be noted that the magnetic rods 220 may be an electromagnetic structure, which has magnetism when the coil is energized and demagnetizes when the coil is de-energized; the magnetic rods 220 may also be a permanent magnet structure such as a strong magnetic nepheline magnetic rod 220 or a magnetic sheet. The magnetic rods 220 are disposed on the same side of the carrier plate 210 so as to be able to extend into the solution cylinder 120 to adsorb the target in the solution. It should also be noted that the supporting plate 210 is matched with the opening of the solution cylinder 120, which specifically refers to the size of the supporting plate 210 being able to close the opening of the solution cylinder 120. At the same time, when the supporting plate 210 closes the opening of the solution cylinder 120, the magnetic rod 220 arranged on the same side of the supporting plate 210 can be fully extended into the solution cylinder 120 to adsorb the target object; and the sealing effect of the supporting plate 210 on the solution opening can ensure that the solution in the solution cylinder 120 is in a closed space during the action of the separation component 20, thereby reducing the risk of splashing out of the solution cylinder 120.

[0037] Furthermore, the driving assembly mainly includes a lifting unit 30 and a transposition unit 40, wherein the lifting unit 30 is used to move in the vertical direction to achieve position change, and the vertical direction here is the vertical direction under the condition that the base 10 is placed on a horizontal plane. The lifting unit 30 is a unit that runs in a straight line, which can be realized by a motor. In some embodiments of the present invention, the lifting unit 30 is provided with a lifting motor and drives the transmission screw to rotate, and the sliding block provided on the transmission screw can slide in the length direction of the screw under the premise of limiting on both sides, thereby achieving position change in the vertical direction. At the same time, if Figure 4 As shown, a rotating module 310 is provided on one side of the lifting unit 30. It should be noted that the rotating module 310 is entirely provided on the sliding block so as to be able to follow the sliding block to achieve position adjustment in the vertical direction when the lifting motor is in motion. The rotating module 310 is used to achieve docking and locking with the separation component 20 so as to achieve transportation of the separation component 20. Specifically, the rotating module 310 includes a supporting plate 3130 extending outwardly and a stirring motor 3110 provided at one end of the supporting plate 3130. It should be noted that the support plate 3130 is provided based on a cantilever structure extending outwardly from the lifting unit 30, and the stirring motor 3110 is provided at one end of the supporting plate 3130 away from the lifting unit 30, so as to enable the stirring motor 3110 to change its position in the vertical direction in an area at a certain distance from the lifting unit 30 through the cantilever structure.

[0038] Based on the above structure, the docking and locking between the rotation module 310 and the separation component 20 can be achieved through snap connection locking or magnetic attraction locking. When the lifting unit 30 drives the rotation module 310 to adjust the position in the vertical direction, the rotation module 310 drives the separation component 20 to change its position. That is, the lifting unit 30 can drive the separation component 20 to insert into and take out of the solution cylinder 120 through the action of the lifting motor. At the same time, due to the setting of the stirring motor 3110, the rotation module 310 can independently start the stirring motor 3110 to drive the separation component 20 to rotate. When the lifting unit 30 drives the separation component 20 to insert into the solution cylinder 120, the bearing plate 210 matching the opening of the solution cylinder 120 can keep the solution cylinder 120 in a good airtight state. At this time, when the rotation module 310 starts the stirring motor 3110, it can drive the magnetic bar 220 to rotate and stir in the solution cylinder 120. The solution in the airtight space can be more uniform under the stirring action of the magnetic bar 220 and will not splash out.

[0039] The above structure can realize the automatic extension, taking out and stirring effect of the separation component 20 in the solution cylinder 120. For the multiple placement stations 110 on the base 10, the transposition unit 40 in the driving component can realize the switching of the separation unit between different placement stations 110, so as to further improve the automation degree of the magnetic separation device. Specifically, the transposition unit 40 is arranged to carry the lifting unit 30, and drives the lifting unit 30 to move through its transposition effect, and then drives the rotation module 310 to move so that it can pass directly above each placement station 110 in sequence or at intervals, and then drives the rotation module 310 to adjust its position in the vertical direction through the action of the lifting motor. It should be noted that the transposition unit 40 can adopt the structure of X, Y, and Z-direction sliding rails cooperating with linear motors. Only by keeping the three-direction sliding rails covering the positions of each placement station 110 on the base 10 can the position switching adjustment of the lifting unit 30 between each placement station 110 be realized; at the same time, the transposition unit 40 can also realize the position switching through rotational movement. In some embodiments of the present invention, the multiple placement stations 110 on the base 10 are arranged around the transposition unit 40, and the lifting unit 30 is arranged directly above the transposition unit 40. The transposition unit 40 rotates through the transposition motor to make the lifting unit 30 face different placement stations 110, and the rotation module 310 in the lifting unit 30 can be located directly above different placement stations 110 through the length setting of the support plate 3130, so as to transfer the separation component 20.

[0040] In the magnetic separation device provided in the above embodiment, the separation assembly 20 can be independently arranged on one side of the base 10. However, at this time, the driving range of the transposition unit 40 needs to include the installation position of the separation assembly 20 to be able to pick up the separation assembly 20. Based on the specific structure of the carrier plate 210, the separation assembly 20 can also occupy a placement station 110, that is, the solution cylinder 120 at this placement station 110 is empty and only for placing the separation assembly 20. At this time, the transposition unit 40 only needs to meet the position switching between the placement stations 110 to meet the driving of the separation assembly 20. On this basis, when magnetic separation of the solution in the target placement station 110 is required, the transposition unit 40 in the driving assembly is activated to drive the rotation module 310 to move directly above the placement station 110 where the separation assembly 20 is arranged. The transposition unit 40 maintains its position fixed and waits for the lifting unit 30 to move. The lifting unit 30 drives the rotation module 310 to move towards the separation assembly 20 until it is locked with the separation assembly 20. Then the lifting unit 30 drives the rotation module 310 to rise until the separation assembly 20 completely leaves the empty solution cylinder 120. The transposition unit 40 switches positions so that the lifting unit 30 drives the separation assembly 20 to be directly above the target placement station 110 through the rotation module 310. The transposition unit 40 maintains its position fixed, and the lifting unit 30 drives the rotation module 310 to descend until the magnetic rod 220 in the separation assembly 20 is inserted into the solution cylinder 120 at the target placement station 110, and the carrier plate 210 closes the opening of the solution cylinder 120. The stirring motor 3110 in the rotation module 310 is started to drive the separation assembly 20 to rotate, and the solution in the solution cylinder 120 is uniformly stirred by means of the rotation effect of the magnetic rod 220, and after stirring for a preset time, it stops to wait for the magnetic rod 220 in the separation assembly 20 to perform magnetic adsorption separation in the solution cylinder 120. After the separation assembly 20 completes the magnetic separation of the solution in the solution cylinder 120 at the target placement station 110, the driving assembly transfers the separation assembly 20 to other stations or areas for desorption of the target substance through the cooperation of the lifting unit 30 and the transposition unit 40, and the target substance is obtained. The cyclic action of the above operation process can realize the automatic magnetic separation process of the solution at different stations, which not only reduces manual operation and improves the separation and purification efficiency, but also improves the effect of the magnetic separation and purification process of biological samples through closed-space operation and stirring process.

[0041] Furthermore, in the magnetic separation device provided by the embodiments of the present invention, the accurate docking of the rotation module 310 and the separation component 20 is the basis for the separation component 20 to achieve the functions of transportation and stirring. Therefore, in some embodiments of the present invention, a docking port 2110 is provided on the carrier plate 210, and a locking block 3120 is provided on one side of the motor shaft of the stirring motor 3110. It should be noted that the structure of the locking block 3120 is preferably diamond-shaped, rectangular, etc., so as to achieve rotational locking in the circumferential direction after being inserted and matched with the docking port 2110, and when the stirring motor 3110 is started, a rotational driving force can be applied to the carrier plate 210 through the locking block 3120, thereby driving the magnetic rod 220 to rotate inside the solution cylinder 120 to achieve the stirring action of the solution.

[0042] It should be noted that the setting of the docking port 2110 and the locking block 3120 in the above embodiments is for locking the rotation module 310 and the separation component 20 in the circumferential rotation direction, while the locking of the rotation module 310 and the separation component 20 in the vertical direction can be achieved through a snap structure or a magnetic attraction structure, so that the rotation module 310 can drive the separation component 20 to move in the vertical direction under the drive of the lifting unit 30.

[0043] To ensure the accurate docking of the rotation module 310 and the separation component 20 and reduce the damage to the equipment during the repeated operation process, in the magnetic separation device provided in this embodiment, a first sensor 230 is further provided on the carrier plate 210, and a second sensor 3140 is correspondingly provided on the side of the rotation module 310 facing the carrier plate 210. The first sensor 230 and the second sensor 3140 are used to align in a single direction to achieve the alignment of the docking port 2110 and the locking block 3120 in this direction. The first sensor 230 and the second sensor 3140 can be self-return sensors or transmissive sensors. Taking the first sensor 230 and the second sensor 3140 as transmissive sensors as an example, the first sensor 230 and the second sensor 3140 are arranged facing each other. The first sensor 230 emits a signal, and the rotation module 310 provided with the second sensor 3140 moves following the lifting unit 30 under the driving action of the transposition unit 40. When the second sensor 3140 is directly above the first sensor 230 during the movement of the rotation module 310, the second sensor 3140 receives the signal emitted by the first sensor 230 and feeds back to stop the motor of the transposition unit 40 from driving. At this time, the rotation module 310 is in place and can move towards the separation component 20 under the drive of the lifting motor, thus achieving the accurate docking of the locking block 3120 and the docking port 2110.

[0044] It should be noted that, in order to avoid the problem of positioning deviation of a single set of sensors, at least two first sensors 230 are arranged at intervals on the carrier plate 210. Correspondingly, on the side of the rotation module 310 facing the carrier plate 210, a second sensor 3140 with the same number as the first sensors 230 and corresponding one by one is arranged, so as to ensure the accurate positioning and docking of the docking port 2110 and the locking block 3120 through the positioning function of two or more groups.

[0045] Furthermore, in the above embodiment, the separation assembly 20 simultaneously has the functions of a stirring device and a magnetic adsorption separation device. After the separation assembly 20 completes the adsorption of the target in a single solution cylinder 120, it needs to be transported to other workstations by the driving assembly for desorption of the target. It should be noted that in the present disclosure, the magnetic rod 220 in the separation assembly 20 can be an electromagnet, and its coil is energized during the adsorption process in the solution to have magnetism and adsorb the target. When it is transported to the workstation for desorption by the driving assembly, the coil is powered off, so that the magnetic rod 220 loses magnetism and the target falls off under the action of gravity to complete the collection. Similarly, the magnetic rod 220 in the separation assembly 20 can be a magnet such as a rubidium magnet 220 or a magnetic sheet. It stirs and magnetically adsorbs synchronously in the solution cylinder 120. At the same time, when desorption is required, it is transported to the desorption workstation by the driving assembly, and the desorption of the target is realized by physical limiting, flushing, scraping and other methods.

[0046] Furthermore, in order to reduce the damage of the stirring action of the separation assembly 20 to the magnetic rod 220 and the ineffective adsorption of other substances in the solution, in some embodiments of the present invention, the magnetic separation device further includes a stirring assembly 50. Specifically, the stirring assembly 50 includes a stirring cover 510 and a stirring cylinder 520 arranged on the stirring cover 510. Similar to the carrier plate 210, the stirring cover 510 can also match the opening of the solution cylinder 120 to be able to close the opening position of the solution cylinder 120 and maintain the airtight state of the solution cylinder 120. The stirring cylinder 520 is arranged on the same side of the stirring cover 510 so as to extend into the interior of the solution cylinder 120 to contact the solution to be separated when the stirring cover 510 closes the solution cylinder 120. Similarly, the rotation module 310 can also be docked and locked with the stirring cover 510. Specifically, a locking port 5110 is opened on the stirring cover 510, and a locking block 3120 is arranged on the motor shaft of the stirring motor 3110 to be able to insert into the locking port 5110 to realize rotational locking with the stirring cover 510. It should be noted that the locking block 3120 used for docking with the docking port 2110 on the carrier plate 210 and the locking port 5110 on the stirring cover 510 on the motor shaft of the stirring motor 3110 can be universal, so as to reduce the structural complexity and improve the generalization degree of the rotation module 310.

[0047] Based on the above structure, as Figures 4 - 8As shown, when stirring is required in the solution cylinder 120, the driving assembly first drives the stirring assembly 50 to move through the lifting unit 30, so as to effectively stir the solution in the solution cylinder 120 at the target placement station 110 through the closing and rotating actions of the stirring assembly 50. Then, the separation assembly 20 is replaced and extended into the solution for magnetic separation. The independently operating device can reduce the loss of the separation assembly 20 and improve its service life.

[0048] Meanwhile, on the basis of the above embodiment, the separation assembly 20 can also act in combination with the stirring assembly 50 to achieve a convenient stirring, adsorption and desorption process. Specifically, the number of stirring cylinders 520 is the same as that of the magnetic rods 220, and their positions correspond one by one. At the same time, the upper side of the stirring cylinder 520 is provided with an opening vertically upward. The corresponding arrangement of the stirring cylinder 520 and the magnetic rod 220 means that the magnetic rod 220 can be inserted into the interior of the stirring cylinder 520 from the top of the stirring cylinder 520 to form a structure in which the separation assembly 20 and the stirring assembly 50 are stacked. On the basis of this structure, when separation operation is required at the target placement station 110, the driving assembly first transports the stirring assembly 50 into the solution cylinder 120 at the target placement station 110, closes the opening of the solution cylinder 120 through the stirring cover 510, and then starts the rotation module 310 to fully stir the solution in the solution cylinder 120. After the stirring is completed, the driving assembly drives the separation assembly 20 to move and fit with the stirring assembly 50, so that the magnetic rod 220 is inserted into each stirring cylinder 520, and the magnetic target in the solution is adsorbed through the outer wall of the stirring cylinder 520. After the adsorption for a set time, the driving assembly locks the separation assembly 20 and the stirring assembly 50 simultaneously through the rotation module 310, and drives the integrated structure of the separation assembly 20 and the stirring assembly 50 to move to the desorption station, and the magnetic target adsorbed on the outer wall of the stirring cylinder 520 is desorbed by itself under the action of gravity by separately withdrawing the magnetic rod 220 from the stirring cylinder 520, thus completing a single magnetic adsorption action. The above structure enables the separation assembly 20 not to participate in the stirring action and not to be in direct contact with the solution, thereby improving the service life of the separation assembly 20. At the same time, the magnetic rod 220 can adopt a permanent magnet structure that is easier to set and has a lower cost, which can achieve the rapid desorption of the magnetic target by means of the stirring cylinder 520, and further improve the operation efficiency.

[0049] Further, in order to ensure that the rotation module 310 can be smoothly docked and locked with the stirring cover 510, in some embodiments of the present invention, similar to the carrier plate 210, at least two third sensors 530 are spaced apart on the stirring cover 510, and a fourth sensor 3150 is correspondingly arranged on the side of the rotation module 310 facing the stirring cover 510. The third sensor 530 and the fourth sensor 3150 are aligned in a single direction to position the locking port 5110 and the locking block 3120, and after the positioning is completed, the accurate docking of the locking block 3120 and the locking port 5110 is achieved through the action of the lifting unit 30. It should be noted that the positioning methods of the third sensor 530 and the fourth sensor 3150 are similar to those of the first sensor 230 and the second sensor 3140, and will not be elaborated herein.

[0050] In order to improve the intelligence and automation of the magnetic separation device provided by the embodiments of the present invention, the magnetic separation device further includes a controller 60 and a display screen 70. Among them, the controller 60 is used to realize the automatic control of each component. It is communicatively connected with the driving assembly to be able to start and stop and control the action directions of the lifting unit 30, the transposition unit 40, and the rotation module 310. Through the controller 60, it can also be communicatively connected with each sensor to confirm the realization of the action. The actions of each component of the magnetic separation device can be realized through preset operations or real-time adjustments via the controller 60; the display screen 70 is communicatively connected with the controller 60 to display the operation process of the controller 60, and can display the operating states of the solution cylinders 120 in each placement station 110. At the same time, the user can also perform real-time manual adjustment on the controller 60 in a touch-screen operation manner to improve the operation diversity of the magnetic separation device.

[0051] Further, in order to improve the matching degree between the separation component 20 and the solution cylinder 120 in the embodiments of the present invention, a fifth sensor 1210 is also arranged at the edge position of the solution cylinder 120. When the carrier plate 210 completely closes the opening of the solution cylinder 120, it can cover each fifth sensor 1210 to cause a signal change in the fifth sensor 1210, thereby ensuring that the carrier plate 210 is in place in matching with the opening of the solution cylinder 120. At the same time, it should be noted that at least two fifth sensors 1210 are arranged at both ends of a diameter of the opening of the solution cylinder 120 to avoid the risk of misalignment when the carrier plate 210 covers the fifth sensor 1210.

[0052] It should be further noted that for the stirring cover 510 on the stirring component 50, its stable docking effect with the opening of the solution cylinder 120 can also be ensured through the positioning function of the fifth sensor 1210.

[0053] Further, in some embodiments of the present invention, the carrier plate 210 is a disc structure, and a plurality of magnetic rods 220 are uniformly arranged along the circumferential direction of the central axis of the carrier plate 210. The number of magnetic rods 220 can be appropriately increased or decreased according to different working conditions. At the same time, a protective sleeve can be provided on the outer wall of the magnetic rod 220, and the material of the protective sleeve can be an inert polymer material such as polypropylene or polytetrafluoroethylene to improve the service life of the magnetic rod 220.
