Problems solved by technology

[0002] Cell culture technology is an indispensable process in many biomedical experiments. Usually, culture bottles are used for culture. When harvesting cells, it is necessary to use auxiliary equipment such as cell scrapers to remove the cultured cells from the culture bottle. , use a cell scraper to collect cells from the culture flask, which does less damage to the cells, and can contact all the surfaces where the cells grow as much as possible, and the collection effect is also better; however, the current cell scraper can only move in one direction driven by the handle It is inconvenient to adjust the angle when scraping the cells in the culture flask, and the range of angle change is limited. If you want to scrape the cells in the entire culture flask, you need to rotate the culture flask, or turn the knife handle substantially, which is inconvenient to operate and will Affect the collection effect of cells

Abstract

The invention relates to the technical field of bio-medical apparatuses, and in particular discloses a cell scraper capable of rotating within 180 degrees. The cell scraper comprises a scraper handle(1) and a scraper head (2), wherein an inclined plane (3) is arranged at one end of the scraper handle; a rotating pillar (4) and a limiting strip (5) are arranged on the inclined plane from outer endto inner end; the scraper head comprises a blade (6) and a connecting plate (7) which is arranged on the blade; an arc-shaped groove (8) is formed in the connecting plate; an arc-shaped block (9) isarranged at one side of the arc-shaped groove in the connecting plate; the arc-shaped block is combined with the arc form of the arc-shaped groove, so that a through hole (10) is defined; the rotatingpillar is rotatably arranged in the through hole; an end, which partially exceeds the arc-shaped block, is arranged at the end of the connecting plate; and a stopping strip (11), which interacts withthe limiting strip, is formed on the part, exceeding the arc-shaped block, of the connecting plate. The cell scraper provided by the invention has the characteristics of being convenient in angle adjusting, relatively wide in angle change range, convenient to operate and relatively good in collection effect.
