Description

Technical Field

[0001] This utility model relates to the field of cell culture device technology, and in particular to a stem cell culture flask support. Background Technology

[0002] Mesenchymal stem cells (MSCs) are pluripotent stem cells derived from the mesoderm. They can be isolated and obtained from diverse tissues such as bone marrow and adipose tissue, possessing strong proliferative capacity and multi-lineage differentiation potential. MSCs have shown great promise in tissue engineering, gene therapy, and immunotherapy, bringing new hope and breakthroughs to the medical field and playing a crucial role in the treatment and research of various diseases. Cell culture flasks are commonly used in stem cell culture and passage, and are the most widely used vessels in cell culture technology. During cell passage, it is often necessary to place the culture flask vertically for adding culture medium or to tilt it for mixing. Therefore, an adjustable cell culture flask support is needed that can accommodate both vertical and tilting functions. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the defects of the existing technology. This utility model proposes a stem cell culture flask support, which can keep the cell culture flask in a vertical or tilted state in the device.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a stem cell culture flask support, comprising:

[0005] The first L-shaped upright plate includes a first vertical plate, a first base plate is fixedly connected to one side of the first vertical plate, a slot is provided on the first base plate, and a slot communicating with the slot is provided at the top center of the first base plate.

[0006] The second L-shaped vertical plate includes a second vertical plate, and a second base plate is fixedly connected to one side of the second vertical plate. The second base plate can be inserted into multiple slots. The height of the second vertical plate is lower than that of the first vertical plate.

[0007] The first and second vertical plates can be used together to place the stem cell culture flasks vertically or at an angle.

[0008] Furthermore, a fixing mechanism is provided on the second base plate to keep the second base plate inserted into the slot stable;

[0009] The fixing mechanism includes a first threaded rod, and the first threaded rod is fixedly connected to both the front and back sides of the second base plate. The front and back sides of the first base plate are provided with elongated grooves that communicate with the slot holes. The first threaded rod slides in the elongated grooves, and a first nut is threadedly connected to the outer wall of the first threaded rod, so that the first threaded rod is fixed to the first base plate.

[0010] Furthermore, a friction layer is provided on the upper surface of the first base plate.

[0011] Furthermore, a second fixing plate is fixedly connected to the top center of the side of the first base plate away from the second vertical plate, and a third threaded rod is fixedly connected to both the front and back sides of the second fixing plate. At least one second sleeve plate is sleeved on the outer wall of the third threaded rod, and a first locking mechanism is provided on the third threaded rod to stably lock the second sleeve plate on the third threaded rod.

[0012] A first fixing plate is fixedly connected to the top of the second vertical plate near the first vertical plate. A second threaded rod is fixedly connected to both the front and back of the first fixing plate. At least one first sleeve plate is fitted on the outer wall of the first fixing plate. A second locking mechanism is provided on the second threaded rod to stably lock the first sleeve plate onto the second threaded rod.

[0013] Furthermore, the first locking mechanism includes a third nut, which is threaded onto the outer wall of the third threaded rod, and a third nut is provided on both sides of each of the second sleeve plates.

[0014] Furthermore, the second locking mechanism includes a second nut, which is threadedly connected to the outer wall of the second threaded rod, and a second nut is provided on both sides of each of the first sleeve plates.

[0015] Compared with the prior art, the beneficial effects of this utility model include:

[0016] During cell passage, after digestion and centrifugation, cells are transferred to culture flasks at an appropriate ratio, and culture medium is added to the flasks. The cell culture flasks can be placed on a base plate, and the short second L-shaped upright plate can be adjusted to secure them, preventing the flasks from tipping over and causing contamination. This also facilitates the experimenter's operation and makes cell passage easier. Since cell digestion and pipetting generally require tilting the culture flasks, this invention also allows adjustment of the second L-shaped upright plate to tilt the culture flasks and maintain this tilted position.

[0017] Multiple stem cell culture flasks can be placed to meet the needs of large-scale cell passage, reducing the workload of operators and the possibility of contamination. Furthermore, multiple stem cell culture flasks can be placed vertically or at an angle, and by separating them, cross-contamination is prevented.

[0018] By adjusting the position of the second L-shaped upright plate, various types and sizes of stem cell culture flasks can be placed. Attached Figure Description
