Description

Technical Field

[0001] The utility model relates to the technical field of cell screening, and more particularly to a cell screen with a novel structure. Background Art

[0002] In cell experiments, cell sieves are often needed to screen cell suspensions. During the use of common cell sieves, the cell suspension often forms a water film seal at the top opening of the cell sieve and the mouth of the centrifuge tube, resulting in the inability to discharge the air in the centrifuge tube normally, forming high pressure in the centrifuge tube, and the cell suspension cannot pass through the cell sieve smoothly.

[0003] Secondly, the bottom outlet screen of the common cell screen is set horizontally. After the cell suspension passes through the screen smoothly, it will form droplets in the center of the screen and flow into the centrifuge tube, causing bubbles in the cell suspension in the centrifuge tube, thereby affecting cell activity. Utility Model Content

[0004] The purpose of the utility model is to provide a cell screen with a new structure, in order to solve the technical problems existing in the background technology.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A novel cell screen structure, comprising:

[0007] A cell sieve tube body, wherein the top of the cell sieve tube body is provided with a top opening, and the bottom of the cell sieve tube body is provided with a bottom outlet; the top opening and the bottom outlet are connected;

[0008] a first handle mounted on one side of the top opening;

[0009] The body of the cell sieve tube forms an arc-shaped indentation on the opposite side of the handle;

[0010] a second handle, the second handle being arranged on the side of the inward arc;

[0011] The inclined screen is arranged on the bottom outlet, and the high end of the inclined surface is on the same side as the arc depression.

[0012] In some embodiments, the lower end of the inclined screen is disposed on one side of the first handle.

[0013] In some embodiments, the inclined screen forms an angle of 60°-70° with respect to the vertical direction of the cell sieve tube body.

[0014] In some embodiments, two second handles are provided, and are respectively disposed at the two ends of the inward arc.

[0015] In some embodiments, the length of the first handle is longer than the length of the second handle.

[0016] In some embodiments, the pore size of the inclined screen is 100-500 μm.

[0017] In some embodiments, the cell screen tube body includes a cell screen frame and a sidewall screen disposed on the cell screen frame.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. This new cell sieve has an inclined screen at the bottom outlet. The inclined screen at the bottom outlet forms an angle of 60°-70° with the vertical direction of the cell sieve tube. When filtering the cell suspension, under the action of gravity, the cell suspension passing through the screen will flow down the centrifuge tube wall quickly and smoothly without generating bubbles, which greatly reduces damage to the cells.

[0020] 2. This new cell sieve adopts a non-standard circular structure. An arc-shaped indentation is formed on the opposite side of the first handle, forming a gap between the cell sieve tube body and the centrifuge tube wall. When filtering the cell suspension, the gas in the centrifuge tube can be discharged smoothly. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following will be combined Figure 1-Figure 2 , a novel cell screen structure involved in the examples of the present application is described in detail. It is worth noting that the following examples are only used to explain the present application and do not constitute a limitation of the present application.

[0030] Embodiment 1:

[0031] like Figure 1-2 As shown, a cell screen of a novel structure comprises: a cell screen tube body, a first handle 2, a second handle 3, and a slanted screen 4. The top of the cell screen tube body is provided with a top opening, and the bottom of the cell screen tube body is provided with a bottom outlet; the top opening and the bottom outlet are connected; the first handle 2 is installed on one side of the top opening; the cell screen tube body forms an arc indentation on the opposite side of the handle; the second handle 3 is arranged on one side of the arc indentation; the slanted screen 4 is arranged on the bottom outlet, and the high end of the slope is on the same side as the arc indentation; the low end of the slanted screen 4 is arranged on one side of the first handle 2.

[0032] The bottom outlet screen is a sloped screen 4, which forms a 60-70° angle with the vertical direction of the cell sieve tube. When filtering the cell suspension, gravity guides the cell suspension passing through the sloped screen 4 to flow quickly and smoothly along the centrifuge tube wall, eliminating the generation of bubbles and significantly reducing damage to the cells. This novel cell sieve structure also adopts a non-standard circular structure. The opposite side of the cell sieve handle forms an arc-shaped indentation, which increases the gap between the cell sieve tube and the centrifuge tube wall. This allows for smooth discharge of gas from the centrifuge tube during filtration.

[0033] In some embodiments, the second handles 3 are provided with two and are respectively arranged at the two ends of the arc inward. When in use, the three handles are used to maintain the balance of the cell sieve tube body.

[0034] In some embodiments, the length of the first handle 2 is longer than the length of the second handle 3, so as to facilitate single-handed taking and placing via the first handle 2.

[0035] The screen mesh used in this invention is made of suitable materials such as nylon membrane or polyester mesh with different pore sizes, with the pore size of the nylon membrane or polyester mesh ranging from 100 to 500 μm. The cell sieve tube body includes a cell sieve frame 5 and a sidewall screen mesh 1 disposed on the cell sieve frame 5. The sidewall screen mesh 1 has the same structure and material as the screen mesh.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
