OVERMOLDED TUBING ASSEMBLY AND ADAPTER FOR A POSITIVE DISPLACEMENT PUMP

摘要

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.

主权项

1. 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 gripper having a plurality of prongs defining cylindrical openings such that each of said plurality of prongs grip an interior surface of a tube wall defining one of the plurality of lumens adjacent said first end of the body; a second tube gripper having a plurality of prongs defining cylindrical openings such that each of said plurality of prongs grip an interior surface of a tube wall defining one of the plurality of lumens adjacent said second end of the body; 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; and 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 and second external system interfaces are molded over the first and second tube grippers respectively to form a seal on an exterior surface of the tube walls defining the plurality of lumens 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.
