Technical Field

[0001] This utility model relates to the field of stem cell culture technology, and specifically to a culture medium mixing device for stem cell culture. Background Technology

[0002] Cell culture, also known as cell cloning technology, is a crucial process in biology, requiring the mixing of various nutrient solutions. This process is essential for both the broader field of bioengineering and the specific application of biological cloning.

[0003] Currently, mixing is mostly done in test cups. After adding various culture media, the mixture is stirred manually or using a mixing device. However, this method results in uneven mixing, affecting the quality of cell culture. Furthermore, culture media residue remains on the inner wall after mixing, making subsequent cleaning difficult. Therefore, a culture medium mixing device for stem cell culture is proposed to facilitate the scraping off of nutrient media adhering to the inner wall of the mixing vessel. This device also allows for the removal and cleaning of the inner wall during subsequent cleaning, improving the mixing effect and quality. Utility Model Content

[0022] To facilitate the scraping off of nutrient solution adhering to the inner wall of the mixing tank, the deposits can also be scraped off and cleaned during subsequent cleaning of the inner wall, improving the mixing effect and quality. Figure 1-4 As shown, the culture medium mixing device for stem cell culture of this utility model includes a base 1, a hydraulic cylinder 6 and a discharge valve 11. The top of the base 1 is provided with a receiving tray 2 and an auxiliary telescopic column 3. A support plate 4 is welded to the top of the base 1 on the side corresponding to the receiving tray 2. A placement plate 8 is provided on the front side of the support plate 4. A mixing tank 9 is provided on the top of the placement plate 8. A control panel 10 is provided on the top of the support plate 4.

[0023] The mixing tank 9 is equipped with stirring blades 14 and concave scrapers 15. The top of the mixing tank 9 is equipped with a top cover 16, and a motor 17 is located at the center of the top of the top cover 16.

[0024] When in use, add various nutrient solutions into the mixing tank 9, and move the handle 19 to move the arc-shaped baffle 18 to seal the opening on one side of the top cover 16. The top and bottom of the arc-shaped baffle 18 are covered with silicone sealing strips. When closed, it can block the gap at the connection with the top cover 16, forming a certain degree of sealing and preventing the nutrient solution in the mixture from splashing out of the mixing tank 9.

[0025] When the motor 17 drives the rotating roller 13 to rotate, it also drives the stirring blade 14 and the concave scraper 15 to rotate, which can fully and evenly stir the various nutrient solutions in the mixing tank 9, resulting in a good mixing effect. The outer side of the scraper is in contact with the inner wall of the mixing tank 9, and can scrape off the nutrient solution adhering to the inner wall of the mixing tank 9 along the annular guide rail 12, avoiding excessive nutrient solution adhering to the inner wall, preventing uneven mixing, and affecting the mixing effect.

[0026] Restarting the control panel 10 simultaneously activates the hydraulic cylinder 6, which drives the mounting plate 7 to move the placement plate 8 and the mixing tank 9, allowing for easy height adjustment to accommodate different tank heights and facilitate filling. Then, using the control panel 10 to open the discharge valve 11 allows for the quantitative discharge of the mixed culture solution.

[0027] To facilitate adjustment of the height of mixing tank 9, for example, as shown... Figure 1 , Figure 2 As shown, the present invention also includes two sets of mounting grooves 5 on the front side of the support plate 4, a hydraulic cylinder 6 is mounted on the top of the mounting groove 5 by bolts, a mounting plate 7 is welded to the bottom drive end of the hydraulic cylinder 6, and one end of the mounting plate 7 is connected to the placement plate 8 by bolts.

[0028] For example, such as Figure 1 , Figure 2 , Figure 3 As shown, the present invention also includes a bottom of the mixing tank 9 connected to the discharge valve 11 via a pipe passing through a reserved opening at the top of the placement plate 8.

[0029] During use, the hydraulic cylinder 6 drives the mounting plate 7 to move the placement plate 8 and the mixing tank 9, which facilitates height adjustment and can adapt to different tank heights, making filling convenient. Then, the control panel 10 is used to open the discharge valve 11 to discharge the mixed culture solution in a quantitative manner.

[0030] For example, such as Figure 1 , Figure 3 As shown, this utility model also includes a guide rail 12 on the upper half of the inner wall of the mixing tank 9, a rotating roller 13 connected to the bottom of the top cover 16 at the bottom of the mixing tank 9 via a rotating shaft, a stirring blade 14 evenly provided from top to bottom on the outer periphery of the rotating roller 13, and a concave scraper 15 installed on the bottom of the outer periphery of the rotating roller 13 by bolts, and the side of the concave scraper 15 is arc-shaped and slidably connected to the guide rail 12 via a slider.

[0031] When in use, the motor 17 drives the rotating roller 13 to rotate, which in turn drives the stirring blade 14 and the concave scraper 15 to rotate. This can fully stir the various nutrient solutions in the mixing tank 9, resulting in a good mixing effect. The outer side of the scraper is in contact with the inner wall of the mixing tank 9, and can scrape off the nutrient solution adhering to the inner wall of the mixing tank 9 along the annular guide rail 12, avoiding excessive nutrient solution adhering to the inner wall and preventing uneven mixing that would affect the mixing effect.

[0032] For example, such as Figure 1 , Figure 4 As shown, the present invention also includes an arc-shaped baffle 18 provided in the mounting groove on one side of the top cover 16, and the top of the arc-shaped baffle 18 is connected to the inner wall of the top cover 16 through a rotating shaft, and a handrail 19 is installed at one point of the top of the arc-shaped baffle 18 by bolts.

[0033] When in use, the handle 19 is turned to move the arc-shaped baffle 18 into the mounting groove of the top cover 16, so that multiple nutrient solutions can be added into the mixing tank 9 at any time. The top and bottom of the arc-shaped baffle 18 are covered with silicone sealing strips. When closed, the gap at the connection with the top cover 16 can be blocked to form a certain degree of sealing and prevent the nutrient solution in the mixture from splashing out of the mixing tank 9.

[0034] For example, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, this utility model also includes an electrical connection between the output end of the control panel 10 and the auxiliary telescopic column 3, the hydraulic cylinder 6, the discharge valve 11, and the input end of the motor 17, respectively, via wires.

[0035] When in use, the hydraulic cylinder 6 is activated via the control panel 10 to adjust the height of the mixing tank 9 and the amount of nutrient solution discharged, and the motor 17 is activated to drive the stirring blade 14 to rotate and mix the nutrient solution evenly.

[0036] When using this utility model, multiple nutrient solutions are added into the mixing tank 9. The handle 19 is turned to drive the arc-shaped baffle 18 to seal the opening on one side of the top cover 16. The top and bottom of the arc-shaped baffle 18 are covered with silicone sealing strips. When closed, the gap at the connection with the top cover 16 can be blocked to form a certain degree of sealing and prevent the nutrient solution in the mixture from splashing out of the mixing tank 9.

[0037] When the motor 17 drives the rotating roller 13 to rotate, it also drives the stirring blade 14 and the concave scraper 15 to rotate, which can fully and evenly stir the various nutrient solutions in the mixing tank 9, resulting in a good mixing effect. The outer side of the scraper is in contact with the inner wall of the mixing tank 9, and can scrape off the nutrient solution adhering to the inner wall of the mixing tank 9 along the annular guide rail 12, avoiding excessive nutrient solution adhering to the inner wall, preventing uneven mixing, and affecting the mixing effect.

[0038] Restarting the control panel 10 simultaneously activates the hydraulic cylinder 6, which drives the mounting plate 7 to move the placement plate 8 and the mixing tank 9, allowing for easy height adjustment to accommodate different tank heights and facilitate filling. Then, using the control panel 10 to open the discharge valve 11 allows for the quantitative discharge of the mixed culture solution.
