Abstract
A multi-functional specimen collector comprises a barrel, a shaft body disposed in the barrel, a piston disposed in the barrel and connected to the shaft body, a first seal cap connected to an end of the barrel, and a second seal cap for connecting to the piston after the shaft body is removed. An interior at the end of the barrel is disposed a stopper for restricting a moving range of the piston inside the barrel to prevent the piston from being pulled out of the barrel. The outer diameter of the stopper and the inner diameter of the barrel are designed to closely fit each other. The inner diameter of the stopper might be smaller than the outer diameter of the piston, and the inner diameter of the stopper might be larger than the largest outer diameter of the shaft body.
