Abstract

A peristaltic pump comprises a drive assembly, a hose pump, and a hose bracket. The drive assembly is rotatably disposed within a frame to move a roller along a pumping path with respect to the frame. The pump hose has rigid hose ends connected by a bendable hose section with limited flexibility tending to bias the pump hose towards a substantially unbent shape. The hose bracket has a rigid body with a first central opening sized to receive the rigid hose ends at first and second retention locations, such that the natural bias of the pump hose towards a substantially unbent shape retains the hose ends within the first and second retention locations, positioning the bendable hose section along the pumping path of the roller.

First claim

The invention claimed is:

1. An installation method for a pump hose of a peristaltic pump, the method comprising:
bending a flexible section of the pump hose to bring together hose couplings of the pump hose at either end of the flexible section;
inserting the hose couplings into a central opening of an outer hose bracket;
releasing the pump hose, such that a natural unbending bias of the flexible section retains the hose couplings at mounting locations of the central opening;
attaching an inner hose bracket to simultaneously abut the hose couplings and the outer hose bracket, thereby discouraging the pump hose from disengaging from the outer hose bracket; and
locking the inner and outer hose brackets together into a location where the pump hose abuts rollers of the peristaltic pump.

2. The installation method of claim 1 , wherein locking the inner and outer hose brackets together into a location where the pump hose abuts rollers of the peristaltic pump comprises inserting first ends of the inner and outer hose brackets into a retention slot of a rigid frame, and attaching a fastener through second ends of the inner and outer hose brackets opposite the first ends to lock both hose brackets into the retention slot.

3. The installation method of claim 2 , wherein inserting the first ends of the hose brackets into the retention slot and attaching the fastener tightly secures the inner hose bracket against both the outer hose bracket and the hose couplings of the pump hose, thereby reducing or eliminating vibration of the pump hose with respect to the frame and the inner and outer hose brackets.

4. The installation method of claim 2 , wherein the fastener is a threaded screw, such that attaching the fastener comprises inserting the fastener through the inner and outer hose brackets and threading the fastener into the frame.

5. The installation method of claim 1 , wherein the central opening is circumscribed by a perimeter defining the mounting locations for the hose couplings, the mounting locations extending outwardly at opposite ends of the central opening.

6. The installation method of claim 5 , wherein the central opening is elongated.

7. The installation method of claim 1 , wherein the outer hose bracket includes a rigid body comprising a substantially flat plate.

8. An installation method for a pump hose of a peristaltic pump, the method comprising:
bending a flexible section of the pump hose to bring together first and second hose couplings of the pump hose that are disposed at first and second ends of the flexible section;
inserting the hose couplings into a first hose bracket;
releasing the pump hose, such that a natural unbending bias of the flexible section retains the hose couplings at mounting locations of the first hose bracket; and
locking the first hose bracket to the peristaltic pump so that the first hose bracket retains the pump hose within the peristaltic pump.

9. The installation method of claim 8 , wherein the first hose bracket comprises a first opening that is sized to allow the bendable hose section to pass therethrough and circumscribed by a perimeter defining first and second mounting locations sized to retain the hose couplings.

10. The installation method of claim 8 , further comprising:
attaching a second hose bracket to abut the hose couplings and the first hose bracket, thereby discouraging the pump hose from disengaging from the first hose bracket; and
locking the first and second hose brackets together into a location where the pump hose abuts rollers of the peristaltic pump.

11. The installation method of claim 10 , wherein the second hose bracket has a second opening sized to allow the bendable hose section to pass therethrough, and retainer portions shaped to contact the hose couplings while the second hose bracket is secured to the first hose bracket.

12. The installation method of claim 10 , wherein the step of attaching the second hose bracket to abut the hose couplings and the first hose bracket includes simultaneously abutting the hose couplings with the first hose bracket.

13. The installation method of claim 10 , wherein locking the first and second hose brackets together into a location where the pump hose abuts rollers of the peristaltic pump comprises:
inserting first ends of the first and second hose brackets into a retention slot of a rigid frame; and
attaching a fastener through second ends of the first and second hose brackets opposite the first ends of the hose brackets to lock the first and second hose brackets into the retention slot.

14. The installation method of claim 13 , wherein inserting the first ends of the hose brackets into the retention slot and attaching the fastener tightly secures the second hose bracket against both the first hose bracket and the hose couplings of the pump hose, thereby inhibiting vibration of the pump hose with respect to the frame and the hose brackets.

15. The installation method of claim 13 , wherein the fastener is a threaded screw, such that attaching the fastener comprises inserting the fastener through both of the hose brackets and threading the fastener into the frame.

16. An installation method for a pump hose of a peristaltic pump, the method comprising:
bending a flexible section of the pump hose, the pump hose having rigid hose couplings at first and second pump hose ends, and the flexible section having stiffness tending to bias the pump hose towards a substantially unbent shape to bring together the hose ends;
inserting the flexible section of the pump hose through a first opening of a first hose bracket, wherein the first opening is sized to allow the flexible section of the pump hose to pass therethrough; and
releasing the pump hose, such that the stiffness of the flexible section of the pump hose retains the hose ends in the first opening.

17. The installation method of claim 16 , wherein the first opening is circumscribed by a perimeter defining first and second retention locations that are sized to receive the hose ends.

18. The installation method of claim 17 , wherein the first opening is elongated and the first and second retention locations extend outwardly at opposite ends of the first opening.

19. The installation method of claim 16 , further comprising:
attaching a second hose bracket to abut the hose ends and the first hose bracket, thereby discouraging the pump hose from disengaging from the first hose bracket; and
locking the first and second hose brackets together into a location where the pump hose abuts rollers of the peristaltic pump.

20. The installation method of claim 19 , wherein locking the first and second hose brackets together into a location where the pump hose abuts rollers of the peristaltic pump comprises:
inserting first ends of the first and second hose brackets into a retention slot of a rigid frame; and
attaching a fastener through second ends of the first and second hose brackets opposite the first ends of the hose brackets to lock both hose brackets into the retention slot.
