Description

Technical Field

[0001] This utility model relates to the field of stem cell culture auxiliary devices, and in particular to a waste liquid collection device for stem cell culture. Background Technology

[0002] Stem cells are a type of cell with unlimited or immortal self-renewal capacity, capable of producing at least one type of highly differentiated daughter cells.

[0003] During stem cell culture, operations such as passage of adherent cells and collection of suspension cells generate a large amount of cell supernatant waste liquid, and existing containers for collecting waste liquid are mostly waste liquid tanks.

[0004] Sometimes, when stem cell waste liquid is poured into the waste liquid tank, the waste liquid splashes out of the tank, thus polluting the environment.

[0005] To address this, we designed a waste liquid collection device for stem cell culture that allows the poured stem cell waste liquid to come into contact with the cotton cloth, thereby reducing the risk of splashing. Furthermore, the filter holes in the conical cover allow the waste liquid to flow out more quickly when a large amount is poured in. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the defects of the existing technology. This utility model proposes a waste liquid collection device for stem cell culture, which allows the poured stem cell waste liquid to come into contact with the cotton cloth, thereby reducing the risk of stem cell waste liquid splashing. In addition, the filter holes of the cone-shaped cover can make the poured stem cell waste liquid flow out faster when there is a lot of it.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a waste liquid collection device for stem cell culture, comprising:

[0008] Stem cell waste fluid collection bucket;

[0010] A pressing mechanism that allows the conical cotton cloth to be stably pressed onto the conical cover;

[0011] The collection bag mechanism includes a connecting pipe, a pipe, and a waste liquid collection bag. The bottom of the stem cell waste liquid collection tank is connected to the connecting pipe, and the end of the connecting pipe away from the stem cell waste liquid collection tank is connected to the pipe, which is connected to the waste liquid collection bag.

[0012] Furthermore, the bottom of the stem cell waste collection tank is fixedly connected to a support leg.

[0013] Furthermore, limiting plates are fixed on both sides of the outer wall near the bottom of the conical cover, and the farthest distance between the two limiting plates is slightly smaller than the inner diameter of the stem cell waste collection bucket.

[0014] Furthermore, the pressing mechanism includes an annular plate, with side plates fixedly connected to both sides of the outer wall near the top of the annular plate, and a circular sleeve plate fixedly connected to the bottom of the annular plate. The inner wall of the circular sleeve plate has a groove, and the inner wall of the groove presses against the outer wall of the conical cotton cloth. The inner wall of the stem cell waste liquid collection bucket is fixedly connected to both sides of the inner wall near the top of the bucket, with a threaded groove in the fixed plate. A screw is threaded into the threaded groove and presses against the top of the side plate.

[0015] Furthermore, wedge-shaped guide blocks are fixedly connected to both sides of the middle part of the inner wall of the stem cell waste collection tank, and the two wedge-shaped guide blocks guide the annular plate.

[0016] Furthermore, a flow-guiding conical groove is provided at the bottom of the stem cell waste collection tank, and a flow-guiding hole is provided at the bottom of the flow-guiding conical groove.

[0031] Example 1:

[0032] Key reference Figure 1-3 The device mainly includes a stem cell waste collection tank 1, a conical cover 16, and a conical cotton cloth 18.

[0033] The bottom of the stem cell waste liquid collection tank 1 is fixedly connected to a support leg 5.

[0034] The outer wall of the conical cover 16 has evenly distributed filter holes 17, and the outer wall of the conical cover 16 is covered with a conical cotton cloth 18.

[0035] Limiting plates 21 are fixed on both sides of the outer wall near the bottom of the cone-shaped cover 16. The farthest distance between the two limiting plates 21 is slightly smaller than the inner diameter of the stem cell waste liquid collection tank 1.

[0036] Side plates 4 are fixedly connected to both sides of the outer wall near the top of the annular plate 3. A circular ring plate 19 is fixedly connected to the bottom of the annular plate 3. A groove 20 is opened on the inner wall of the circular ring plate 19. The elastic rubber layer of the inner wall of the groove 20 is pressed onto the outer wall of the conical cotton cloth 18. Fixing plates 13 are fixedly connected to both sides of the inner wall near the top of the stem cell waste liquid collection bucket 1. A threaded groove 14 is opened in the fixing plate 13. A screw 15 is threadedly connected to the threaded groove 14. The screw 15 is pressed onto the top of the side plate 4.

[0037] Both sides of the inner wall of the stem cell waste fluid collection tank 1 are fixedly connected to wedge-shaped guide blocks 2, and the two wedge-shaped guide blocks 2 guide the annular plate 3.

[0038] The bottom of the stem cell waste liquid collection tank 1 is connected to a connecting pipe 8. The end of the connecting pipe 8 away from the stem cell waste liquid collection tank 1 is connected to a pipe 11, and the pipe 11 is connected to a waste liquid collection bag 12.

[0039] Example 2: Based on Example 1, a technical means was added to enable the separated liquid to flow stably to the waste liquid collection bag 12.

[0040] Key reference Figure 1 This embodiment mainly includes a flow-guiding conical groove 6 and a flow-guiding hole 7.

[0041] The bottom of the stem cell waste collection tank 1 is provided with a flow guide cone groove 6, and the bottom of the flow guide cone groove 6 is provided with a flow guide hole 7. A connecting pipe 8 is fixedly installed at the bottom of the stem cell waste collection tank 1. The connecting pipe 8 is connected to the flow guide hole 7. A connecting sleeve 10 is fixedly installed on the connecting pipe 8, and the pipe 11 is installed on the connecting sleeve 10.

[0042] A valve 9 is installed on the connecting pipe 8.

[0043] The other features of Example 2 are the same as those of Example 1.

[0044] In practice, the conical cotton cloth 18 is first placed on the outer wall of the conical cover 16. The conical cover 16 is then placed at the bottom of the stem cell waste collection tank 1. Note that the initial placement of the limiting plate 21 should not press against the fixing plate 13.

[0045] Next, place the annular plate 3 into the stem cell waste collection container 1. Note that the side plates 4 should not initially press against the fixing plate 13. Then, press the inner wall of the groove 20 against the outer wall of the conical cotton cloth 18. Next, rotate the annular plate 3 so that the two side plates 4 are positioned at the bottom of the two fixing plates 13. Then, rotate the two screws 15 to ensure that the inner wall of the groove 20 is stably and smoothly pressed against the outer wall of the conical cotton cloth 18, thus stably installing the conical cotton cloth 18 on the outer wall of the conical cover 16.

[0046] The conical sleeve-shaped cotton cloth 18 separates solids onto itself, while liquid flows out through the filter holes 17 on the conical cover 16. The flowing liquid flows from the connecting pipe 8 into the waste liquid collection bag 12. When a certain amount of liquid has been collected in the waste liquid collection bag 12, the valve 9 is closed, and a new waste liquid collection bag 12 is used to collect the liquid.

[0047] When it is necessary to replace the new conical cotton cloth 18, loosen the screw 15 so that the inner wall of the groove 20 is no longer pressed against the outer wall of the conical cotton cloth 18, making it easy to replace the new conical cotton cloth 18 and remove the solids adsorbed on the outer wall of the conical cotton cloth 18.

[0048] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
