When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.
[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.
[0032] The utility model provides a cup centrifugal device, which can be used to centrifuge samples into cups. In one embodiment, please refer to Figures 1 to 3 The cup centrifugation device includes a workbench 1 and a transfer structure 2. The workbench 1 can provide an operating environment for the centrifugation operation of the sample on the one hand, and can also provide a supporting function on the other hand.
[0033] The workbench 1 specifically includes a first sample transfer area 11, a centrifugal structure 12 and a second sample transfer area 13 arranged in sequence along a first direction. The first sample transfer area and the second sample transfer area 13 are used to transfer sample liquid, and the centrifugal structure 12 is used to centrifuge the sample liquid.
[0034] Specifically, the first sample transfer area 11 includes a centrifuge tube loading position 115, a left centrifuge tube tray position 112, and a sample tube loading position 118, and the second sample transfer area 13 includes a right centrifuge tube tray position 137 and a wall-breaking tube plate position 131. The centrifuge tube loading position 115 is used to stack trays containing centrifuge tubes, and the trays containing centrifuge tubes can be stacked up and down on the centrifuge tube loading position 115 manually or by using a robotic arm.
[0035] The transfer structure 2 is disposed on the workbench 1, and the transfer structure 2 is used to transfer the tray and the sample. Among them, the transfer structure 2 includes a first transfer component 22 and a second transfer component 23 that can move back and forth along a first direction, the first transfer component 22 has a first clamping member 2212 and a first pipetting member 2222 that can move in a second direction perpendicular to the first direction, and the second transfer component 23 has a second clamping member 2312 and a second pipetting member 2322 that can move in the second direction perpendicular to the first direction. Thus, the first clamping member 2212, the first pipetting member 2222, the second clamping member 2312, and the second pipetting member 2322 can all move in the first direction and the second direction. It should be noted that the plane defined between the first direction and the second direction is parallel to the working plane of the workbench 1. Figure 2 As shown, the X-axis and the Y-axis represent the first direction and the second direction respectively.
[0036] When the first clamping member 2212 moves, it can clamp the centrifuge tube tray containing centrifuge tubes located at the centrifuge tube loading position 115 to the left centrifuge tube tray position 112 to wait for the centrifuge tube to be transferred. The first clamping member 2212 can clamp the centrifuge tubes located in the centrifuge tube tray and the sample tubes located at the sample tube loading position 118 to the predetermined positions, respectively, and the predetermined positions can facilitate the transfer of the sample liquid in the sample tube to the centrifuge tube. Specifically, when the sample tube and the centrifuge tube are transferred to the predetermined positions, the first liquid transfer member 2222 can transfer the sample in the sample tube to the centrifuge tube after sucking it when it moves. At this time, the first clamping member 2212 can transport the centrifuge tube containing the sample to the centrifugal structure 12 for centrifugal treatment.
[0037] When the second clamping member 2312 moves, the centrifuge tube after centrifugation can be transported from the centrifuge structure 12 to the right centrifuge tube tray position 137, and the second clamping member 2312 can transport the centrifuge tube located at the right centrifuge tube tray position 137 and the broken wall tube located at the broken wall tube plate position 131 to a predetermined position, which is convenient for transferring the centrifuged sample liquid in the centrifuge tube to the broken wall tube. When the second liquid transfer member 2322 moves, the centrifuged sample in the centrifuge tube can be sucked and transferred to the broken wall tube.
[0038] The first sample transfer area 11, the centrifugal structure 12 and the second sample transfer area 13 are arranged on the workbench 1, and the first sample transfer area 11 is correspondingly provided with the first transfer assembly 22, and the second sample transfer area 13 is correspondingly provided with the second transfer assembly 23. The first clamping member 2212 can transfer the centrifuge tube and the sample tube to a predetermined position, the first liquid transfer member 2222 can divide the sample liquid in the sample tube into cups, and transport the sample liquid to the centrifuge tube, and the first clamping member 2212 can transport the centrifuge tube containing the sample liquid to the centrifugal structure 12 for centrifugal treatment. The second clamping member 2312 can transfer the centrifuged centrifuge tube again, and transfer the centrifuge tube containing the centrifuged sample and the wall-breaking tube to a predetermined position, and then divide the centrifuged sample liquid in the centrifuge tube into cups and the wall-breaking tube through the second liquid transfer member 2322.
[0039] In the whole process, the cupping and centrifugation process does not require manual operation, which greatly saves manpower, and the workbench 1 is divided into two transfer areas, and the first transfer components 22 and the second transfer components 23 in the two transfer areas can work at the same time, that is, the cupping operation can be performed simultaneously in the first sample transfer area 11 and the second sample transfer area 13, so as to increase the detection efficiency. In addition, the cooperation of the first clamping member 2212, the first liquid transfer member 2222, the second clamping member 2312 and the second liquid transfer member 2322 can make the cupping more accurate and reduce the experimental error compared with manual cupping.
[0040] In one embodiment, see Figures 1 to 3 The workbench 1 has a working end 14, which is the end that the experimenter approaches during operation. The transfer structure 2 is connected to an end of the workbench 1 away from the working end 14. The centrifuge tube loading position 115 and the sample tube loading position 118 are arranged at intervals along the first direction, and the sample tube loading position 118 is relatively close to the centrifuge structure 12. The left centrifuge tube tray position 112 and the centrifuge tube loading position 115 are arranged at intervals along the second direction, and the centrifuge tube loading position 115 is arranged relatively close to the working end 14.
[0041] It should be noted that the first sample transfer area 11 also includes a left switch cover position 117 arranged on the workbench 1 and located between the centrifuge tube loading position 115 and the sample tube loading position 118. The first clamping member 2212 can clamp the centrifuge tube located at the left centrifuge tube tray position 112 and the sample tube located at the sample tube loading position 118 to the left switch cover position 117 respectively, so as to open the covers of the centrifuge tubes and the sample tubes.
[0042] The left switch cover position 117 is the predetermined position of the centrifuge tube and the sample tube mentioned above. The first clamping member 2212 has a retractable and rotatable clamping end, which can not only utilize the telescopic function to pull the centrifuge tube and the sample tube out of the tray respectively, and then utilize the first clamping member 2212 to move in the first direction and the second direction to place the centrifuge tube and the sample tube at the left switch cover position 117, and then utilize the clamping end of the first clamping member 2212 to unscrew the caps of the centrifuge tube and the sample tube, and after the first pipetting member 2222 transfers the sample to the centrifuge tube, the first clamping member 2212 can screw on the caps of the centrifuge tube and the sample tube again.
[0043] It should be noted that the first sample transfer area 11 also includes a left pipette loading position 114 and a left pipette discarding position 116 which are arranged on the workbench 1 and are located between the centrifuge tube loading position 115 and the left centrifuge tube tray position 112. The first pipette member 2222 can move to the left pipette loading position 114 to replace or install the pipette at the left pipette loading position 114. The first pipette member 2222 uses the pipette to achieve liquid suction and liquid discharge. The first pipette member 2222 can discard an old or used pipette at the left pipette discarding position 116.
[0044] It is worth mentioning that the first sample transfer area 11 also includes a left centrifuge tube pre-storage position 111 and a left reagent loading position 113. The left centrifuge tube pre-storage position 111 is located between the left centrifuge tube tray position 112 and the sample tube loading position 118, and the left reagent loading position 113 is close to the end of the left centrifuge tube tray position 112 facing away from the sample tube loading position 118. The left centrifuge tube pre-storage position 111 can pre-store multiple centrifuge tube trays. Since it is close to the left centrifuge tube tray position 112, it can save more time in subsequent operations. The left reagent loading position 113 can act as a sample source, which can store multiple samples. The samples stored there can not only be used for centrifugation, but also for other experiments.
[0045] In one embodiment, see Figures 1 to 3The centrifugal structure 12 includes a centrifugal position 121, a pick-and-place position 122, and a centrifuge tube grabbing arm 123. The first clamping member 2212 can place the centrifuge tube with the sample in the pick-and-place position 122. The pick-and-place position 122 is correspondingly provided with a centrifuge tube tray. The centrifuge tube grabbing arm 123 can grab the centrifuge tubes located in the pick-and-place position 122 to the centrifugal position 121 for centrifugal treatment one by one. Then the centrifuge tube grabbing arm 123 can grab the centrifuged centrifuge tubes into the centrifuge tube tray. After the tray is full of centrifuge tubes, the second clamping member 2312 can grab the entire tray to the right centrifuge tube tray position 137. It should be noted that the centrifugal structure 12 here is the centrifugal structure 12 in the prior art, which is not elaborated in detail in this application.
[0046] In one embodiment, the wall-broken tube plate position 131 and the right centrifuge tube tray position 137 are arranged at intervals along the first direction, and the wall-broken tube plate position 131 is arranged relatively close to the centrifuge structure 12. The second sample transfer area 13 also includes a right switch cover position 132 arranged on the workbench 1 and located between the wall-broken tube plate position 131 and the right centrifuge tube tray position 137. The second clamping member 2312 can clamp the centrifuge tube located at the right centrifuge tube tray position 137 and the wall-broken tube located on the wall-broken tube plate position 131 to the right switch cover position 132 for opening and closing the cover.
[0047] The second clamping member 2312 also has a clamping end that can be extended and rotated to clamp and screw on the centrifuge tube and the wall-breaking tube.
[0048] It should be noted that the second sample transfer area 13 also includes a centrifuge tube unloading position 135 spaced apart from the right centrifuge tube tray position 137 , and a right pipette loading position 133 and a right pipette discarding position 134 are also provided between the centrifuge tube unloading position 135 and the right centrifuge tube tray position 137 .
[0049] The second pipetting component 2322 uses the pipette thereon to divide the sample in the centrifuge tube into cups to transfer the sample to the wall-breaking tube, and the centrifuge tube with the sample transferred is placed back on the centrifuge tube tray, and the first clamping arm 221 can grab the entire centrifuge tube tray and place the tray at the centrifuge tube unloading position 135 to wait for unloading.
[0050] The second pipetting component 2322 can replace and install the pipette at the right pipette loading position 133 , and can discard the used pipette at the right pipette discarding position 134 .
[0051] It is worth mentioning that the second sample transfer area 13 also includes a right centrifuge tube pre-storage position 138 and a right reagent loading position 136. The right centrifuge tube pre-storage position 138 is located between the right centrifuge tube tray position 137 and the wall-breaking tube plate position 131, and the right reagent loading position 136 is close to the end of the right centrifuge tube tray position 137 facing away from the wall-breaking tube plate position 131. The right centrifuge tube pre-storage position 138 can pre-store multiple centrifuge tube trays that have been centrifuged. Since it is close to the right centrifuge tube tray position 137, it can save more time during subsequent operations. The right reagent loading position 136 can also serve as a sample source, which can store a variety of samples. The samples stored there can not only be used for centrifugation, but also for other experiments.
