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.
Claims20
A tubing and adapter assembly for a peristaltic pump, the tubing and adapter 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;
- a first tube mount having a first side wall defining a first tube interface surface, the first tube interface surface having at least one opening, a first end wall opposite the first tube interface surface, the first end wall and the first side wall defining a first recess;
- a second tube mount having a second side wall defining a second tube interface surface, the second tube interface surface having at least one opening, a second end wall opposite the second tube interface surface, the second end wall and the second side wall defining a second recess;
- a first external system interface having an annular surface defining a first flow passage, a first tubing interface portion, a first pump interface portion, and a first mounting interface portion;
- a second external system interface having an annular surface defining a second flow passage, a second tubing interface portion, a second pump interface portion, and a second mounting interface portion;
- wherein the first end of the elongate body is configured to be coupled with the first tube mount and the first external system interface and the second end of the elongate body is configured to be coupled with the second tube mount and the second external system interface such that a rotor of the peristaltic pump can operate against the tubing and adapter assembly for pumping fluid through the tubing and adapter assembly.
An adapter assembly for a tube of a peristaltic pump, the assembly comprising:
- a tube mount having an orifice for receiving a first end of the tube of the peristaltic pump;
- an external system interface having an orifice for receiving the first end of the tube of the peristaltic pump;
- and
- at least one pump tubing gripper configured to fit within the first end of the tube of the peristaltic pump;
- wherein the tube mount and the external system interface are coupled together.
A method of manufacturing a clamp-less tubing assembly for a peristaltic pump, comprising:
- inserting a first end of a tube through an orifice in a tube mount;
- pressing a pump tubing gripper into the first end of the tube;
- pressing the first end of the tube within an orifice of an external system interface;
- and
- coupling the tube mount to the external system interface.
