DISPENSER

摘要

PURPOSE:To enhance accuracy in dispensation by providing a tube squeezing/ feeding section with a tube squeezing roller for squeezing a tube selectively to select and set the length at the tube squeezing part thereby preventing slippage of the tube. CONSTITUTION:The forward end 20 of a tube projecting from a nozzle 7 is inserted into serum in a specimen container 14 contained in a specimen rack 15. A pair of tube squeezing rollers 5 having identical diameter are turned by a set amount to the suction side based on a command set by a squeezing amount setting means 22 thus feeding a tube 2 to the left. The tube 2 is squeezed by the roller 5 and sucks the serum. Consequently, the tube nozzle part B ascends onto a rack 17 set with containers to be dispensed and then it is lowered such that the forward end 29 enters into the vessel 16. The roller 5 then squeeze the tube based on a command from the means 22 to deliver a desired quantity of serum. After repeating the operation by required number of times, the nozzle part B is moved above a discarded tube receiver 10 and a predetermined length of tube is fed out through a feed roller 11 before the tube is cut off by a cutting means.
