Abstract
A fluid delivery system includes a control interface and multiple unique loading guides. The control interface of the fluid delivery system receives a fluid pump assembly. The multiple loading guides are retractable from the fluid delivery system to retain and control movement of a facing of the fluid pump assembly to contact the control interface on the facing of the fluid delivery system. In one configuration, the control interface is disposed in a cavity of the fluid delivery system; the multiple loading guides are disposed at locations in proximity to the cavity. The multiple loading guides slidably retract in unison to support substantially orthogonal insertion of the fluid pump assembly into the cavity of the fluid delivery system.
Claims20
A fluid delivery system comprising:
- a control interface configured to control a disposable fluid pump assembly;
- multiple retractable loading guides to retain the disposable fluid pump assembly and control movement of the retained disposable fluid pump assembly to contact the control interface;
- wherein the multiple retractable loading guides include a first loading guide and a second loading guide, the first loading guide operable to receive a first tab disposed on a first edge of the disposable fluid pump assembly, the first loading guide including a corresponding channel to receive the first tab, the corresponding channel including a stop to retain the first tab in the corresponding channel;
- wherein the second loading guide includes a respective channel operable to receive a second tab disposed on a frame of the disposable fluid pump assembly, the second tab disposed on a second edge of the disposable fluid pump assembly;
- and
- wherein the stop is operable to align the disposable fluid pump assembly for subsequent matable coupling of a port of the disposable fluid pump assembly to a port of the control interface, the control interface disposed on a facing of the fluid delivery system.
A method comprising:
- receiving a fluid pump assembly;
- inserting the fluid pump assembly into multiple retractable loading guides of a fluid delivery system, the multiple retractable loading guides retaining the fluid pump assembly;
- and
- subsequent to the multiple retractable loading guides retaining the fluid pump assembly, initiating movement of the multiple retractable loading guides to move a facing of the retained fluid pump assembly into contact with a control interface of the fluid delivery system, the control interface disposed on a facing of the fluid delivery system;
- wherein the multiple retractable loading guides include a first loading guide and a second loading guide, the first loading guide operable to receive a first tab disposed on a first edge of the fluid pump assembly, the first loading guide including a corresponding channel to receive the first tab, the corresponding channel including a stop to retain the first tab in the corresponding channel;
- wherein the second loading guide includes a respective channel operable to receive a second tab disposed on a frame of the fluid pump assembly, the second tab disposed on a second edge of the fluid pump assembly;
- and
- wherein the stop aligns the disposable fluid pump assembly for subsequent matable coupling of a port of the disposable fluid pump assembly to a port of the control interface.
