Abstract
A volume-regulating device for medical fluids has a button body, which expands by an elastic protrusion, to overcome the problems arising from a conventional structure in which the elasticity is provided by coil springs. The present apparatus provides for the storage and the discharging of medical fluids, and by being formed into a single channel, not only enables manufacturing in a small size, but also achieves precise discharging of a volume of medical fluids.
