DETAILED DESCRIPTION

[0033] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices consistent with some aspects of the present disclosure as detailed in the appended claims.

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] Embodiment 1:

[0036] like Figures 1 to 7 As shown, this embodiment proposes a cell centrifuge collector, including a bottom tube 1, a connecting tube 2, an interception component 3, a limit component 4, a sleeve 5, a collecting rubber leather bag 6, a movable hole 7, a control rod 8, a tube cap 9 and a pressing block 11 arranged at the lower end of the control rod 8.

[0037] The lower end of the bottom tube 1 is tapered, and a groove is provided at the position of the variable diameter, so that the sleeve 5 on the lower side can be sleeved on the bottom. The upper end of the bottom tube 1 is open, and a connecting tube 2 which is open both up and down is provided at the upper end of the bottom tube 1. The inner lower side of the connecting tube 2 and the outer upper side of the bottom tube 1 are threadedly connected together, so that the bottom tube 1 and the connecting tube 2 can be connected and the two tubes can be disassembled. A collecting rubber leather bag 6 which is also tapered and fits the inner lower end of the bottom tube 1 under normal circumstances is provided at the inner lower side of the bottom tube 1. After centrifugation, the animal cells agglomerate and fall on the bottom tube 1. The bottom of the collecting rubber leather bag 6 is used for collecting the bottom, the edge of the outer upper end of the collecting rubber leather bag 6 is fixedly connected to the inner wall of the inner lower side of the bottom tube 1, and a control rod 8 is fixedly connected to the outer lower end of the collecting rubber leather bag 6. The lower end of the control rod 8 extends to the outer lower side of the bottom tube 1 through the movable hole 7 opened on the outer lower side of the bottom tube 1, and a pressing block 11 is fixedly connected to the lower end of the control rod 8. The control rod 8 can be used to push the middle of the collecting rubber leather bag 6 upward to deform the collecting rubber leather bag 6, so that the animal cell clusters collected therein can be pushed out of the bottom tube 1.

[0038] After the cells are centrifuged, the upper clarified liquid needs to be poured out. A clamping ring 301 is provided at the upper end of the bottom tube 1 on the lower inner side of the connecting tube 2 after the bottom tube 1 and the connecting tube 2 are tightened. The upper outer side of the clamping ring 301 is an inwardly inclined slope. In order to allow the animal cell agglomerates to slide down along the slope and into the bottom tube 1 during centrifugation and to prevent the clamping ring 301 from blocking the animal cell agglomerates from sliding down, an umbrella-shaped movable interception block 302 is provided inside the bottom tube 1. The outer diameter of the movable interception block 302 is smaller than the inner diameter of the bottom tube 1, but larger than the clamping ring 301. The inner diameter is large, so when the bottom tube 1 and the connecting tube 2 are connected together, the movable intercepting block 302 can block the inside of the clamping ring 301 upward, and when the movable intercepting block 302 is on the outer lower side of the clamping ring 301, the animal cell clusters can fall along the gap between the movable intercepting block 302 and the bottom tube 1, and the movable intercepting block 302 is umbrella-shaped, which reduces the obstruction to the animal cell clusters. The sealing rubber ring 10 is fixedly connected to the outer lower side of the clamping ring 301 to ensure the sealing of the connection between the bottom tube 1 and the connecting tube 2. At the same time, the pipe cap 9 threadedly connected to the outer upper end of the connecting tube 1 can also be screwed on the bottom tube 1.

[0039] Embodiment 2:

[0040] The solution in Example 1 is further introduced below in combination with a specific working method, as described below:

[0041] In order to facilitate the control of the up and down movement of the movable intercepting block 302, a support column 303 is fixedly connected to the outer lower side of the movable intercepting block 302, and a contact ball 304 is fixedly connected to the lower end of the support column 303. The contact ball 304 contacts the inner bottom end of the collecting rubber leather bag 6, and the movable intercepting block 302 is controlled to move upward by pushing up the middle of the collecting rubber leather bag 6, blocking the middle of the clamping ring 301, and then pouring out the clarified liquid on the upper side, leaving the animal cell agglomerates inside the bottom tube 1.

[0042] After pouring out the clarified liquid, use a pipette to remove the small amount of clarified liquid remaining in the bottom tube 1, and pour out the animal cell agglomerates collected by centrifugation from the bottom tube 1. When pouring, first take out the movable intercepting block 302, turn the bottom tube 1 upside down, and pour out the animal cell agglomerates collected in the rubber bag 6 by inertia through bouncing or quickly pressing the pressing block 11.

[0043] Embodiment 3:

[0044] The solution in Example 2 is further introduced below in combination with a specific working method, as described below:

[0045] In order to ensure the smooth up and down movement of the movable intercepting block 302, three connecting rods 401 are fixedly connected around the support column 303 connected to the lower end of the movable intercepting block 302, and the other end of the connecting rod 401 connected to the support column 303 is fixedly connected to an arc-shaped support block 402, and the side of the support block 402 away from the connecting rod 401 is in contact with the inner wall of the bottom tube 1. The friction between the support block 402 and the inner wall of the bottom tube 1 can prevent the movable intercepting block 302 from moving up and down at will during the centrifugation process, ensuring that the contact ball 304 is on the lower side of the collecting rubber leather bag 6, so as to avoid excessive squeezing of the animal cell agglomerates collected inside the collecting rubber leather bag 6 by the contact ball 304 when the movable intercepting block 302 is pressed upward after the centrifugation is completed.

[0046] At the same time, after pushing the movable intercepting block 302 upwards and pouring out the clarified liquid inside the connecting tube 2, the bottom tube 1 and the connecting tube 2 are disassembled, and the upper end of the movable intercepting block 302 can expose a part of the interior of the bottom tube 1, so that the movable intercepting block 302, the support column 303, the contact ball 304, the connecting rod 401 and the support block 402 can be conveniently removed from the interior of the bottom tube 1, and the bottom tube 1 can be inverted to collect the animal cell clusters after centrifugation of the sub-tubes.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
