Description

Technical Field

[0001] The invention relates to the technical field of stem cell culture, and in particular discloses a packaging device for stem cell culture medium. Background Art

[0002] Stem cells are a type of multipotent cells with the ability to self-replicate. Under certain conditions, they can differentiate into a variety of functional cells. Stem cell culture medium is a special culture environment required in the culture process of stem cells to achieve the adhesion or proliferation effect of stem cells. When the stem cell culture medium is packaged and stored, it needs to be stored in a sterile environment. After a period of storage, stem cells need to be taken out and observed regularly. However, when observing, the packaging equipment needs to be opened and the culture medium needs to be taken out, so that the sterile gas in the air will enter the packaging equipment, affecting the culture effect of the culture medium.

[0003] In order to solve the problem of sterile gases in the air entering the filling equipment and affecting the culture, a certain stem cell culture medium filling equipment on the market adopts a closed design for removing the culture medium, which has a certain market share.

[0004] After searching, the invention patent with the announcement number CN116588494B discloses a filling device for stem cell culture medium, including a filling barrel and a culture tube, the bottom end of the inner wall of the filling barrel is provided with a storage mechanism for storing the culture tube, the storage mechanism is provided with an adjustment mechanism for driving the circular motion of the culture tube, one side of the storage mechanism is provided with a material passage slot for the culture tube to slide through; a material guide port is provided on the filling barrel corresponding to the material passage slot, the inner wall of the filling barrel is provided with a sealing mechanism that slides and seals at the material guide port; a push-pull mechanism for driving the culture tube to move is provided at the axis of the bottom end of the inner wall of the filling barrel. Through the setting of the adjustment mechanism, the push-pull mechanism and the sealing mechanism, the culture tube can be taken out in a closed environment, so as to prevent the stem cell culture medium in other culture tubes stored in the filling barrel from being affected during the process of taking out the culture tube, and to prevent the temperature change from affecting the culture effect of the culture medium, thereby improving the use efficiency.

[0005] Based on the above search and in combination with the prior art, it is found that when the existing filling equipment is performing the removal operation for observation of the culture medium, it is necessary to open and close the sealing door and the sealing baffle in sequence.

[0052] In summary, the working principle of the present invention is as follows: when in use, the user sequentially packs the culture dishes 11 for stem cell culture medium on different special culture medium trays 9, and uses the tensioning performance of the spring 29 in the clamping assembly to fit the arc-shaped clamping plate 28 to the outer wall of the culture dish 11, so that the culture dish 11 is fixed in the placement groove 10 of the special culture medium tray 9, and then stacks a plurality of special culture medium trays 9 inside the filling barrel 1, so that the positioning column 24 can be inserted into the first positioning hole 15 and the second positioning hole 25, so as to realize the layered filling operation of the stem cell culture medium, and can also directly take out or put in the entire special culture medium tray 9 when taking out and putting in the culture medium, and then closes the sealing cover 2 on the filling barrel 1, and then the sealing cover 2 is used. The sterilization operation of the sterilizer 33 makes the inside of the dispensing barrel 1 in a sterile state; when the user observes different stem cell culture dishes 11 in different layers, the first forward and reverse motor 1401 in the lifting component 14 is used to drive the first driving gear 1402, the first driven gear 1403 and the threaded rod 1404 to rotate, and the U-shaped seat 1601 in the ejection component 16 is adjusted to rise and fall, and the infrared position transmitter 21, the infrared position receiver 22 and the controller 19 are used to position the height adjustment of the ejection component 16, so that the ejection head 1603 in the ejection component 16 corresponds to the stem cell culture dishes 11 in different layers, and then the user drives the stepping motor 1701 in the rotating component 17 to rotate. The second gear 1702 rotates, and the meshing action of the second gear 1702 and the tooth groove 1703 drives the rotating circle 8 and the superimposed special culture medium tray 9 to rotate, so that the ejection head 1603 corresponds to different stem cell culture dishes 11 at the same level, and then the second forward and reverse motor 1602 in the ejection assembly 16 drives the second driving gear 1606 to rotate, and the meshing action of the second driving gear 1606 and the rack seat 1604 is used to move the ejection head 1603 into the placement groove 10, so that the culture dish 11 is pushed into the inner part of the outer guide box 4, and then the ejection assembly 16 is reset, and the reciprocating electric push rod 602 in the reciprocating lifting mechanism 6 is used to adjust the height of the L-shaped rack 608, driving the first gear 605 and the driving shaft 604 rotate, so that the rack plate 607 and the L-shaped rack 608 form a reverse movement, which quickly drives the two rows of sealing baffles 5 to move, so that the inner material guide box 13 is quickly closed and the outer material guide box 4 is quickly opened, effectively preventing the external sterile air from entering the interior of the filling barrel 1 along the material guide port 20, and realizing the performance of quickly taking out the culture dish 11 in a sealed environment, so that different stem cell culture dishes 11 in different layers can be taken out, which is convenient for observation and can sterilize the internal air of the outer material guide box 4, the material guide port 20 and the inner material guide box 13 under the action of the ultraviolet sterilization lamp 30 in the sterilization component. When the two rows of sealing baffles 5 are reset, it can be ensured that the interior of the filling barrel 1 is always in a sterile state.

[0053] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
