  • Fluid transfer device
    Patent number: 10247312
    Abstract: A disposable device for the sterile transfer of fluids, such as liquids or gases, includes a body, a bore formed through at least a portion of the interior of the body, and a linearly moveable plunger contained within the bore. The body is formed from a rotating section and a stationary section. Partial rotation of the rotating section around a portion of the stationary section and the plunger drives the plunger linearly within the bore, opening and closing the device. The plunger includes at least a first and a second opening, and a fluid channel in the interior of the plunger connecting the first and second openings forming a fluid pathway to downstream components when the device is open. A termination component at one end of the plunger connects to a downstream component. A flange at one end of the body attaches to an upstream component.
    Type: Grant
