Abstract

A multifunctional device featuring a cartridge having first and second ports; first and second chambers which have outlets disposed at proximal ends connected to tubes that bifurcate to form intake lines and deposit lines, wherein one-way valves are disposed in the intake and deposit lines, wherein pistons are disposed in the chambers which oscillate between moving toward the proximal or distal end, when the piston moves toward the distal end a material can be drawn into the chamber and when the piston moves toward the proximal end the material can be pumped out of the chamber; and wherein the intake lines are formed from bifurcation of a main intake fine fluidly connected to the first port; wherein the deposit lines feed into a main deposit line fluidly connected to the second port; wherein the device can pump material from the first port to the second port.
