US 2016/0106903 A1 · Fluid Pump Systems, and Related Methods for Pumping Biological Fluids

Abstract

The present invention relates to a fluid pump system (64) having a fluid reservoir (21) comprising a first cavity (29) and a second cavity (30) in fluidic communication with each other and adapted to accommodate a biological fluid (7). The fluid reservoir (21) is connected to a fluid-container system (27) and a target (5) is in fluidic communication with the second cavity (30). A pressurization system is adapted to generate a first pressure below ambient pressure in the first cavity (29) and generate a second pressure in the first cavity (29). The second pressure is also applied to the second cavity (30). The fluid pump system (64) thereby causes flow of the biological fluid (7) from the fluid-container system (27) into the first cavity (29), from the first cavity (29) into the second cavity (30), and from the second cavity (30) to the target (5).

Dependent claims

A method of pumping a biological fluid to a target said method comprising:

providing a fluid pump system comprising:
a fluid reservoir comprising at least one first cavity and at least one second cavity in fluid communication with each other and configured to accommodate said biological fluid, wherein said at least one second cavity is in fluid communication with said target;
a fluid-container system in fluid communication with said at least one first cavity in said fluid reservoir;
and
a pressurization system configured to generate a pressure in said at least one first cavity and said at least one second cavity;
generating a first pressure below ambient pressure in said at least one first cavity using said pressurization system, thereby causing said biological fluid to flow from said fluid-container system into said at least one first cavity;
generating a second pressure in said at least one first cavity using said pressurization system, thereby causing said biological fluid in said at least one first cavity to flow into said at least one second cavity;
and
applying said second pressure to said at least one second cavity, thereby pumping said biological fluid to said target.
