[0025] 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. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.
[0026] Example 1
[0027] like Figure 1-3 A cell filter fixing device 100, the fixing device comprises a fixing wall 1, a fixing surface 2, and a fixing hole 3; the fixing wall 1 is fixed on a cell collector 200 and is in a cylindrical shape; the fixing surface 2 is fixed above the fixing wall 1 and is inclined at a certain angle to the horizontal plane, and the fixing surface 2 and the fixing wall 1 form a closed space; the fixing hole 3 is arranged on the fixing surface 2, and is used to fix the cell filter 300. The fixing surface 2 and the fixing wall 1 can be designed to be integrally formed. The fixing surface and the fixing wall can also be arranged to be detachably connected.
[0028] The angle between the fixed surface 2 and the vertical surface of the fixed wall 1 is 45 degrees. Setting this angle is more conducive to cell flushing. Specifically, during flushing, the flushing water mist is flushed onto the cell filter screen. Under the action of gravity, the water mist is gathered into a small water flow, which is more conducive to cell flushing and can save the amount of flushing liquid.
[0029] Further, the fixing hole 3 includes a first hole 31 at the top and a second hole 32 at the bottom, and the diameter of the first hole 31 is larger than the diameter of the second hole 32, and the diameter of the second hole 32 is smaller than the outer diameter of the cell filter. Preferably, the diameter of the first hole 31 is the same as the outer diameter of the cell filter. Through the above arrangement, the cell filter can be easily fixed on the fixing hole 3.
[0030] Furthermore, a protruding ring 4 is provided on the inner circumference of the fixed wall 1, and the plane where the center line of the ring 4 is located is perpendicular to the fixed wall. This ensures that when the cell filter fixture is installed on the cell collector, the fixed wall is in a vertical state and the fixed surface 2 is in an inclined state, which is more conducive to cell flushing and water saving. Furthermore, a thread can also be provided on the inner side of the fixed wall 1 to cooperate with the cell collector 200.
[0031] The cell filter 300 is a filter screen fixed on the inner wall of a cylinder. The size of the filter screen is smaller than the size to be filtered, so that the cells can be intercepted above the filter screen. During the specific filtering, another filter screen will be set above the cell filter to filter out particles larger than the cells. After the cell filter has filtered the cells, the cell filter 300 needs to be turned upside down so that the filter screen on the side with cells faces downward, and the filter is installed on the cell filter fixing device 100, and then rinsed with a rinse solution.
[0032] In a laboratory, the cell collector 100 is usually a culture dish, a 50 ml centrifuge tube, a glass container, etc. The water source for flushing the cells is usually a syringe, an electric infusion pump or other devices that can generate flushing water mist.
[0033] Example 2
[0034] like Figure 4 On the basis of Example 1, the inner diameter of the fixing hole 3 is equal to the outer diameter of the cell filter, and a fixing groove 21 is provided on the fixing surface 2. The fixing groove 21 is used to cooperate with a fixing block (not shown) provided on the cell filter, so as to better fix the cell filter 300.
[0035] Furthermore, the cell filter fixing device can also be set to a square shape, and the cell collector 200 should also be set to a square shape. The size of the cell filter fixing device 100 and the cell collector 200 are matched to achieve a good sealing and fixing effect for both.
[0036] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
