Description

Technical Field

[0001] The utility model belongs to the technical field of cell culture, and in particular relates to a cell harvesting bracket for a cell culture bag. Background Art

[0002] Cell culture technology is also known as cell cloning technology. Cell culture can maintain cell survival, achieve cell proliferation and obtain cell metabolic products after cell proliferation. In the process of cell culture, cell culture bags are required for cell culture.

[0003] A Chinese patent with application number CN201922126217.8 discloses a cell harvesting bracket for a cell culture bag, comprising a base, a movable support plate and a pillar, wherein the movable support plate is movably connected to the pillar, a clamp is provided on the movable support plate, a clamping groove is provided on the clamping member, sliders are protruding from both side walls of the clamp, a limit block is provided on the top of the slider, a groove is provided on one side of the upper surface of the movable support plate, and sliding grooves matching the slider are provided on the inner walls on both sides of the groove, and a buffer spring is connected to the bottom end of the slider.

[0004] The above scheme rotates the handle and uses the traction rope to pull the clamp to slide down, thereby tilting the movable support plate to dump the cells. However, in actual use, the bag mouth catheter of the cell culture bag is directly placed in the card slot. As the cell bag tilts, the culture fluid inside it pours out, and the gravity on the cell culture bag is reduced. When the liquid flows, the bag mouth catheter of the culture bag is easily caused to jump due to the lack of fixation of the cell culture fluid catheter, causing the culture fluid to spill, resulting in pollution and waste.

[0005] In view of this, the present utility model is proposed. Utility Model Content
