Description

Technical Field

[0001] The utility model relates to the technical field of experimental equipment, in particular to an improved cell screen. Background Art

[0002] Cell sieves are important tools used in laboratories for cell culture, impurity filtration, cell dispersion and sample separation.

[0003] The traditional disposable cell sieve is a standard circular shape and is used to filter the cell suspension into the centrifuge tube below. The side wall of the sieve fits tightly with the edge of the centrifuge tube to ensure that the cell suspension does not leak from the side during the filtration process. However, this tight fit results in a closed space under the sieve. When the cell suspension fills the bottom and side walls of the sieve, the gas under the sieve is difficult to discharge naturally due to the effect of surface tension, thus affecting the smooth filtration of the cell suspension.

[0004] Therefore, it is necessary to provide an improved cell screen to solve the above technical problems. Utility Model Content

[0005] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides an improved cell screen with notches designed on the bottom and one side of the screen, so that the gas under the cell suspension can be discharged, reducing the resistance of the cell suspension through the screen and improving the filtration efficiency.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] The improved cell screen comprises: a screen bottom and a screen side, wherein the screen bottom is installed at the bottom of the screen side, a cornice is fixedly installed on the top of the screen side, a handle is arranged on the cornice, and a notch is provided on one side of the screen bottom and the screen side, and the whole is in a horseshoe shape.

[0008] Preferably, the cornice matches the shape of the screen, which helps to discharge the air in the centrifuge tube.

[0009] Preferably, a card slot is provided at the bottom of the eaves. When the device is installed on the centrifuge tube mouth, the card slot is stuck on the centrifuge tube mouth, thereby improving the stability of the connection between the device and the centrifuge tube.

[0010] Preferably, the eaves is annular in structure and is provided with a protrusion thereon, the protrusion matches the notch, the protrusion is used to close the notch, a baffle is installed on the protrusion, an air duct is opened at the bottom of the baffle, an air hole is opened on the notch, and the air hole is connected to the air duct.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] (1) By designing gaps at the bottom of the sieve and one side of the sieve, the gas below the cell suspension can be discharged, thereby reducing the resistance of the cell suspension passing through the sieve and improving the filtration efficiency.

[0013] (2) The eaves match the shape of the screen and are fixed to the centrifuge tube mouth through a slot, which enhances the connection stability between the device and the centrifuge tube and prevents displacement or falling off during use.

[0014] (3) By setting up bumps, baffles and airways, the exhaust function is further optimized to ensure that the gas below the cell suspension can be discharged smoothly, avoiding the situation where the cell suspension enters the centrifuge tube without being filtered, and ensuring the accuracy and reliability of the experiment.

[0023] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The present invention includes but is not limited to the following embodiments.

[0024] Example 1

[0025] like Figure 1-3 As shown, the improved cell screen provided by the utility model includes: a screen bottom 1 and a screen side 2, the screen bottom 1 is installed at the bottom of the screen side 2, the top of the screen side 2 is fixedly installed with a cornice 3, and the cornice 3 is provided with a handle 4. The screen bottom 1 and the screen side 2 have a notch 5 on one side, and the whole is a horseshoe shape. When in use, the screen side 2 fits tightly with the edge of the centrifuge tube mouth. When the cell suspension fills the screen bottom, the gas under the screen is discharged through the notch 5, so that the cell suspension can pass through the screen bottom 1 more easily and efficiently, thereby making the cell suspension filtered smoothly.

[0026] The eaves 3 matches the shape of the screen gang 2, which helps to discharge the air in the centrifuge tube. A card slot 6 is provided at the bottom of the eaves 3. When the device is installed on the centrifuge tube mouth, the card slot 6 is stuck on the centrifuge tube mouth, thereby improving the stability of the connection between the device and the centrifuge tube.

[0027] Example 2

[0028] like Figure 4-7 As shown, the eaves 3 is annular in structure, and a convex block 7 is arranged on it, and the convex block 7 matches the notch 5, and the convex block 7 is used to close the notch 5. A baffle plate 8 is installed on the convex block 7, and an airway 9 is opened at the bottom of the baffle plate 8. An air hole 10 is opened on the notch 5, and the air hole 10 is connected with the airway 9. When the cell suspension fills the screen bottom 1, the gas under the screen enters the airway 9 through the notch 5 and the air hole 10, and then is discharged to the outside through the airway 9, thereby ensuring the realization of the exhaust function. The purpose of setting the convex block 7 and the baffle plate 8 is not only to exhaust, but also to prevent the cell suspension from entering the centrifuge tube through the notch 5, because when in use, when personnel pour the cell suspension into the screen, sometimes the phenomenon of pouring too full occurs, and the cell suspension overflows the screen and then enters the centrifuge tube from the notch 5. In the present device, when the cell suspension overflows, the convex block 7 and the baffle plate 8 will prevent the unfiltered cell suspension from entering the centrifuge tube through the notch 5.

[0029] The aperture of the screen bottom 1 in the device can be 40um, 70um or 100um, and the size can be designed into different sizes according to the diameters of different centrifuge tube openings.
