MEDICAL FLUID DELIVERY SYSTEM AND METHOD RELATING TO THE SAME
First Claim
1. A method of operating at least one medical fluid delivery line valve, the method comprising:
- mechanically interfacing a valve controller with a first medical fluid delivery line valve, wherein the valve controller is operable in a first direction and a second direction, wherein operation of the valve controller causes a first activation member associated with the first medical fluid delivery line valve to move to at least a first position and a second position, and wherein operation of the valve controller in the second direction does not actuate the first medical fluid delivery line valve, and wherein operation of the valve controller in the first direction at least partially actuates the first medical fluid delivery line valve during movement of the first activation member from the first position to the second position;
operating the valve controller in the second direction to move the first activation member to the first position, wherein the first medical fluid delivery line valve is not actuated during operation of the valve controller in the second direction; and
operating the valve controller in the first direction to move the first activation member to the second position, whereby the first medical fluid delivery line valve is at least partially actuated.

Abstract
A medical fluid delivery system for the use in the delivery of medical fluids. The medical fluid delivery system may include a pumping system, a disposable medical fluid line set and a valve operating system. The disposable tubing line set may include valves adapted to interface with the valve operating system. The valve operating system may be adapted to operate only selected valves using a single drive means. The pumping system may be operated over a wide range of medical fluid delivery rates by employing a bi-directional drive member and a transmission interfaced with the drive member and a pump.

21. A valve operating system for use in delivering at least two medical fluids, the valve operating system comprising:
-
first and second valve interface members comprising first and second valve actuators adapted to operatively interface with first and second medical fluid delivery line valves, respectively; and
a valve controller mechanically interfaced with the first and second valve interface members, wherein the valve controller is operable in a first direction and a second direction, wherein operation of the valve controller in the first direction causes a first motion output and a second motion output, wherein the first motion output at least partially actuates the first valve actuator and wherein the second motion output at least partially actuates the second valve actuator, and wherein operation of the valve controller in the second direction causes a third motion output that does not actuate the first valve actuator or the second valve actuator. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48)

49. A pumping system for use in delivering a plurality of medical fluids, the pumping system comprising:
a pump configured to pump medical fluid through a medical fluid line, wherein moving a component of the pump in linear response to an angular motion of an angular element mechanically coupled to the component enables placement of a medical fluid line within the pump. - View Dependent Claims (50, 51, 52, 53, 54, 55)

56. A rotary peristaltic pump for use in delivering a plurality of medical fluids, the rotary peristaltic pump comprising:
-
a medical fluid line;
an anvil surface; and
a pump head comprising;
at least one pinch member comprising;
a pinch-roller, at least one pinch-spring, and a pinch-roller shaft;
wherein the medical fluid line is disposed between the anvil surface and the pump head, and wherein the pinch member pinches the medical fluid line against the anvil surface when the anvil surface is moved toward the pump head. - View Dependent Claims (57, 58, 59)
