Face drive fluid pump

Abstract

A fluid pump comprising a fluidic manifold comprising a plate constructed of a fluid-impermeable material. The plate has a pump platen, first fluid connectors, and second fluid connectors, and one or more channels formed therein for connecting the first connectors to the second connectors. The fluid pump has a fluid-impermeable membrane positioned on the plate and covering the one or more fluid channels to form one or more fluid paths. The fluid pump also has a pump tubing positioned on the pump platen, the pump tubing having a first part connected to a first one of the first fluid connectors and a second part connected to a second one of the first fluid connectors such that the pump tubing is fluidly connected to the channels via the first one and the second one of the first fluid connectors.

1 . A fluid pump comprising:
 a fluidic manifold comprising:   a plate constructed of a fluid-impermeable material, the plate having a pump platen, first fluid connectors, and second fluid connectors, and one or more channels formed therein for connecting the first connectors to the second connectors;   a fluid-impermeable membrane positioned on the plate and covering the one or more fluid channels to form one or more fluid paths;   a pump tubing positioned on the pump platen, the pump tubing having a first part connected to a first one of the first fluid connectors and a second part connected to a second one of the first fluid connectors such that the pump tubing is fluidly connected to the channels via the first one and the second one of the first fluid connectors;   a pump drive having two or more rollers engaging the pump tubing and movable in a path following the pump tubing from the first part to the second part, and a source operably connected to the rollers and adapted to move the rollers through the path.   
     
     
         2 . The fluid pump of  claim 1 , wherein the pump tubing comprises two or more portions bonded together such that the pump tubing is substantially impermeable to fluids. 
     
     
         3 . The fluid pump of  claim 1 , wherein the pump tubing comprises a top elastomeric portion and a bottom portion bonded to the top elastomeric portion, such that a fluid-impermeable fluid channel is formed by the top portion and the bottom portion. 
     
     
         4 . The fluid pump of  claim 1 , wherein the fluidic manifold further comprises a valve operably connected to one or more of the fluid paths and operable to selectively direct fluid flow through the plate of the fluidic manifold. 
     
     
         5 . The fluid pump of  claim 1 , wherein the fluidic manifold comprises a top surface and a bottom surface, and wherein the pump platen extends from the top surface and the fluid channels are formed in the bottom surface. 
     
     
         6 . The fluid pump of  claim 1 , wherein the plate is substantially rectangular in shape. 
     
     
         7 . The fluid pump of  claim 1 , wherein the two or more rollers are tapered relative to a rotation axis, such that the rollers are rotatable over an exterior surface of the pump tubing. 
     
     
         8 . The fluid pump of  claim 1 , wherein the first fluid connectors define press-fit connections. 
     
     
         9 . A fluid pump, comprising:
 a fluidic manifold comprising:   a plate having a pump platen;   a pump tubing positioned on the pump platen, the pump tubing having a first portion and a second portion bonded together to form a fluid impermeable connection and a flow channel extending between a first part and a second part the first portion, the first portion being constructed of a fluid impermeable material and positioned on the pump platen, the second portion positioned on the first portion and formed of an elastomeric, fluid impermeable material;   a pump drive having two or more rollers engaging the pump tubing and movable in a path following the pump tubing from the first part to the second part to compress the first portion between the rollers and the pump platen, and a source operably connected to the rollers and adapted to move the rollers through the path.   
     
     
         10 . The fluid pump of  claim 9 , wherein the plate includes first fluid connectors and wherein the first part is connected to a first one of the first fluid connectors, and the second part is connected a second one of the first fluid connectors. 
     
     
         11 . The fluid pump of  claim 10 , wherein the first fluid connectors define press-fit connectors. 
     
     
         12 . A fluidic manifold comprising:
 a plate constructed of a fluid-impermeable material, the plate having a pump platen, first fluid connectors, and second fluid connectors, and channels formed therein for connecting the first fluid connectors to the second fluid connectors; and   a fluid-impermeable membrane positioned onto the plate and covering the channels to form fluid paths.   
     
     
         13 . The fluidic manifold of  claim 12 , further comprising a first surface and a second surface opposite from the first surface, and wherein the pump platen is positioned on the first surface and the channels are formed in the second surface. 
     
     
         14 . The fluidic manifold of  claim 12 , wherein the first fluid connectors define press-fit connections.
