DETAILED DESCRIPTION

[0022] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments. Example

[0023] like Figure 1-3 As shown, the utility model proposes a multifunctional cell scraper, comprising a handle 1, one end of which is fixedly mounted with a main blade 8 for scraping cells in a culture bottle, and further comprising an auxiliary blade 9, which is hinged on both sides of the main blade 8, and a driving mechanism for driving the auxiliary blade 9 to rotate is arranged on the handle 1, so that the main blade 8 enters the cell bottle and the auxiliary blade 9 can be unfolded, thereby increasing the scraping area and improving the scraping efficiency;

[0024] Among them, the auxiliary mechanism is arranged on the handle 1 and is used to flush and remove the cells on the main knife 8 and the auxiliary knife 9, so as to facilitate the removal of the cells attached to the main knife 8 and the auxiliary knife 9 and avoid damaging the cells.

[0025] like Figure 2-3 As shown, the present embodiment also includes a driving mechanism, which includes a connecting plate 19 slidably mounted on the knife handle 1, and mounting plates 10 are hinged on both sides of the connecting plate 19. A connecting block 20 is fixedly mounted on one side of the auxiliary knife 9, and the connecting block 20 is hinged to the connecting plate 19. When the main knife 8 moves into the culture bottle, the connecting plate 19 is moved forward, and the connecting plate 19 drives the mounting plate 10 to move. The mounting plate 10 squeezes the connecting block 20 on one side of the auxiliary knife 9, and the connecting block 20 drives the auxiliary knife 9 to expand outward to increase the scraping area for cells. After scraping, the connecting plate 19 is moved backward, and the connecting plate 19 drives the mounting plate 10 to be pulled outward, and the mounting plate 10 pulls the connecting block 20, so that the auxiliary knives 9 on both sides of the main knife 8 are retracted inward, which is convenient for taking out the equipment and increasing the number of cells taken out at one time.

[0026] like Figure 3-4As shown, the present embodiment also includes an auxiliary mechanism, which includes a mounting groove 4 provided on the knife handle 1, a liquid storage bag 15 is fixedly installed in the mounting groove 4, and is used to store the culture fluid for culturing cells, an extrusion block 5 is slidably installed at one end of the mounting groove 4, a pressing plate 7 is slidably installed on one side of the knife handle 1, the pressing plate 7 is fixedly connected to the extrusion block 5, a connecting rod 6 is fixedly installed at one end of the extrusion block 5, and one end of the connecting rod 6 is fixedly connected to the pressing plate 7, a connecting pipe 16 is fixedly installed at the bottom of the knife handle 1, and a guide cavity 17 is fixedly installed at one end of the connecting pipe 16, and the guide cavity 17 is fixedly installed at one end of the connecting pipe 16. A plurality of nozzles 18 arranged at equal distances are fixedly mounted on the cavity 17, and the distribution angle of the nozzles 18 is 180°. A guide tube 12 is fixedly mounted between the connecting tube 16 and the liquid storage bag 15. After the cells are taken out, the pressing plate 7 is pressed, and the pressing plate 7 squeezes the liquid storage bag 15. The culture fluid in the liquid storage bag 15 is moved from the guide tube 12 to the guide cavity 17 under pressure. As the pressure continues to increase, the culture fluid in the guide cavity 17 is sprayed out from the nozzle 18 to flush the parts of the main knife 8 and the auxiliary knife 9 where the cells are attached, and the cells are flushed to the next culture point.

[0027] like Figure 2-3 As shown, a slide groove 3 is provided on the handle 1, and guide grooves 14 are provided on both sides of the slide groove 3.

A fixing plate 11 is fixedly installed on the bottom of the connecting plate 19, and both sides of the fixing plate 11 are hinged to the mounting plate 10. A push block 2 is fixedly installed on the top of the connecting plate 19.

[0028] Working principle: When it is necessary to scrape the cells in the culture bottle, move the main knife 8 into the culture bottle, push the push block 2 forward, the push block 2 drives the connecting plate 19 to move, the connecting plate 19 drives the mounting plate 10 to move, the mounting plate 10 squeezes the connecting block 20 on one side of the auxiliary knife 9, the connecting block 20 drives the auxiliary knife 9 to expand outward, and increases the scraping area of ​​the cells. After the scraping is completed, move the connecting plate 19 backward, the connecting plate 19 drives the mounting plate 10 to pull outward, and the mounting plate 10 pulls the connecting block 20, so that The auxiliary knives 9 on both sides of the main knife 8 are retracted inward to facilitate the removal of the equipment. After the cells are taken out, the pressure plate 7 is pressed, and the pressure plate 7 squeezes the liquid storage bag 15. The culture fluid in the liquid storage bag 15 is moved from the diversion tube 12 to the diversion cavity 17 under pressure. As the pressure continues to increase, the culture fluid in the diversion cavity 17 is sprayed out from the nozzle 18 to rinse the parts of the main knife 8 and the auxiliary knife 9 where the cells are attached, thereby increasing the scraping area for the cells, increasing the number of cells taken out at one time, improving efficiency, and being highly convenient.
