Peristaltic pump tubing mount and its use
View Patent ↗Peristaltic pump's tubing mount design in this invention uses an “&”-shape tubing routing path to hold a longer tubing section on its entry side to spread pumping motion's shear stress, hence a reduced tubing deformation rate and longer tubing life. Together with a fixed-speed synchronous AC motor, this minimum tubing mount arrangement makes a light weight peristaltic pump of easy tubing mount and dismount and zero-footprint hanging use conveniences, hence added reaches and applications.
1 . A tubing mount arrangement for a peristaltic pump assembly, the peristaltic pump assembly including a pump head, a continuous tubing piece, a driver motor and the tubing mount arrangement, wherein the tubing mount arrangement comprises:
a base plate configured to have the pump head, the continuous tubing piece and the driver motor mounted thereon; and
an inlet end tube anchoring device being mounted adjacent a first side-edge of the base plate and being configured to holding the continuous tubing piece on the base plate; and
at least one tube routing device mounted adjacent a second side-edge of the base plate, the second side-edge being opposite to the first side-edge;
wherein the base plate is configured to have the inlet end tube anchoring device, the at least one tube routing device and the pump head mounted thereto such that when the continuous tubing piece is routed thereon the continuous tubing piece will extends from the inlet end tube anchoring device to wind in a U-turn around the at least one tube routing device, and then pass around a rotor of the pump head to form an “&”-shape tubing path, with a tube routing section around the at least one tube routing device corresponding to a bottom loop of the “&”-shape and another tube routing section around the rotor of the pump head corresponding to a top loop of the “&”-shape.
2 . The tubing mount arrangement of claim 1 , wherein the at least one tube routing device is a round-shape post fixedly and vertically mounted on the base plate, and has a minimum height of twice the diameter of the continuous tubing piece and a flanged top.
3 . The tubing mount arrangement of claim 1 , wherein the at least one tube routing device has two round-shape posts fixedly and vertically mounted on the base plate, each having a minimum height of twice the diameter of the continuous tubing piece and a flanged top; wherein the two round-shape posts are placed apart by at least one diameter of the continuous tubing piece and in line with the inlet end tube anchoring device.
4 . The tubing mount arrangement of claim 1 , wherein the inlet end tube anchoring device uses a T-shaped spring clip and a spring clip sitting slot carved out adjacent the first side-edge of the base plate, to fasten and unfasten the spring clip in order to hold or release respectively an inlet tube section of the continuous tubing piece in one step.
5 . The tubing mount arrangement of claim 1 , wherein the base plate is a metal plate of a rectangular or parallelogram shape.
6 . The tubing mount arrangement of claim 5 , wherein the base plate is made of stainless steel.
7 . A peristaltic pump assembly, comprising:
a pump head;
a continuous tubing piece;
a driver motor; and
a tubing mount arrangement, wherein the tubing mount arrangement comprises:
a base plate on which the pump head, the continuous tubing piece and the driver motor are mounted;
an inlet end tube anchoring device being mounted adjacent a first side-edge of the base plate and holding the continuous tubing piece on the base plate; and
at least one tube routing device mounted adjacent a second side-edge of the base plate, the second side-edge being opposite to the first side-edge;
wherein the continuous tubing piece extends from the inlet end tube anchoring device to wind in a U-turn around the at least one tube routing device to form an “&”-shape tubing path, with a tube routing section around the at least one tube routing device corresponding to a bottom loop of the “&”-shape and another tube routing section around the rotor of the pump head corresponding to a top loop of the “&”-shape.
8 . The peristaltic pump assembly of claim 7 , wherein the at least one tube routing device of the tubing mount arrangement is a round-shape post fixed and vertically mounted on the base plate, and has a minimum height of twice the diameter of the continuous tubing piece and a flanged top.
9 . The peristaltic pump assembly of claim 7 , wherein the at least one tube routing device of the tubing mount arrangement has two round-shape posts fixedly and vertically mounted on the base plate, each having a minimum height of twice the diameter of the continuous tubing piece and a flanged top; wherein the two round-shape posts are placed apart by at least one diameter of the continuous tubing piece and in line with the inlet end tube anchoring device.
10 . The peristaltic pump assembly of claim 7 , wherein the inlet end tube anchoring device of the tubing mount arrangement uses a T-shaped spring clip and a spring clip sitting slot carved out adjacent the first side-edge of the base plate, to fasten and unfasten the spring clip in order to hold or release respectively an inlet tube section of the continuous tubing piece in one step.
11 . The peristaltic pump assembly of claim 7 , wherein the base plate of the tubing mount arrangement is a metal plate of a rectangular or parallelogram shape.
12 . The peristaltic pump assembly of claim 11 , wherein the base plate of the tubing mount arrangement is made of stainless steel.
