Abstract
An exemplary pumping-syringe device for allowing an operator to control a vacuum in a medical device and to expel samples without disconnecting the pumping-syringe device from the medical device. The pumping-syringe device includes a syringe section, a valve section that sealably connects to the syringe and a fitting section connected to the syringe section and the valve section and detachably connects to the medical device. The valve section includes two modes of operation. A first mode of operation allows fluid flow in a first direction between the syringe section and an external environment and a second mode of operation allows fluid flow in a second direction between the syringe section and the external environment.
