High pressure, high flow rate peristaltic pump and tubing assembly

Abstract

A tubing assembly is provided that can comprise a plurality of tubes or lumens that can be disposed within a head of a peristaltic pump. The tubing assembly can provide a flow rate or volume capacity that is generally equal to or greater than that achieved with a comparable prior art tube while operating at higher pressures than that possible using the prior art tube. Further, in accordance with some embodiments, the tubing assembly can achieve a longer working life than a comparable prior art tube, and the load on the pump motor can be reduced such that the pump life is increased and/or a larger pump motor is not required to achieve such advantageous results.

What is claimed is: 
     
         1 . A tubing assembly for a peristaltic pump, the tubing assembly comprising:
 an elongate body defining a longitudinal axis, a first end, and a second end, the elongate body having a plurality of lumens extending along the longitudinal axis, each lumen being surrounded by a tube wall, the plurality of lumens extending from the first end to the second end such that the first end is in fluid communication with the second end of the elongate body, the first end of the elongate body being configured to be coupled with a first tubing connector of the peristaltic pump, the second end of the elongate body being configured to be coupled with a second tubing connector of the peristaltic pump;   wherein the tubing assembly is configured to be inserted into a pump head of the peristaltic pump such that a rotor of the peristaltic pump can operate against the tubing assembly for pumping fluid through the tubing assembly.
