Manual valve actuator for medical fluid delivery set

1. A manual valve actuator for a medical fluid delivery set including a valve mechanism having a valve rotor capable of regulating a flow of fluid delivered from a pump through the valve mechanism, the manual valve actuator comprising:

a holder adapted to removably receive the valve mechanism therein such that removal of the valve mechanism from the holder does not prevent the valve mechanism from regulating fluid flow through the valve mechanism, the holder being shaped to hold the valve mechanism against rotation with respect to the holder;

a valve driver mounted for rotation with respect to the holder about an axis of rotation, the valve driver projecting into the holder to operatively engage the valve rotor when the valve mechanism is received in the holder;

a handle operatively connected to the valve driver for rotating the valve driver and thereby the valve rotor when the valve mechanism is received in the holder; and

a lock positioned with respect to the holder to engage the valve mechanism to prevent removal of the valve mechanism from the holder whenever the valve rotor is in a rotational position permitting fluid flow through the valve mechanism, the lock being moveable to a position to permit removal of the valve mechanism from the holder when the valve rotor is in a rotational position preventing fluid flow through the valve mechanism.

2. A manual valve actuator according to claim 1 wherein the holder comprises a ring and a pocket connected to the ring adapted to removably receive the valve mechanism, the pocket having an open top positioned to receive the valve mechanism into the pocket passing in a direction perpendicular to the axis of rotation of the valve driver, wherein the holder is separate from the pump.

3. A manual valve actuator according to claim 2 wherein the holder further comprises a channel extending from the pocket adapted to removably receive a tube of the medical fluid delivery set connected to the valve mechanism.

4. A manual valve actuator according to claim 2 wherein the valve driver is rotatably disposed within a central opening of the ring.

5. A manual valve actuator according to claim 4 wherein the valve driver is sized and shaped for reception into a recess defined by the valve rotor for engaging the valve rotor.

6. A manual valve actuator according to claim 4 wherein the handle is annular and has a central opening, the ring being disposed within the central opening.

7. A manual valve actuator according to claim 6 wherein the handle and valve driver are connected for conjoint rotation, and wherein the holder has at least one rotational indicator disposed at a predetermined circumferential position along the ring to signify a rotational position at which the handle and valve driver may be rotated to change a fluid flow path through the valve mechanism.

8. A manual valve actuator according to claim 7 wherein the handle has an indicator for alignment with the rotational indicator of the holder.

9. A manual valve actuator according to claim 8 wherein the outer edge of the handle has at least one tab projecting from a periphery of the handle adapted for engaging by a hand of a user and for facilitating rotation of the handle and valve driver.

10. A manual valve actuator as set forth in claim 1 wherein the valve driver is constructed to engage the valve rotor for use in driving rotation of the valve rotor by radial movement of the valve driver with respect to an axis of rotation of the valve rotor.

11. A manual valve actuator according to claim 1 further comprising a detent positioned with respect to the holder such that the detent provides resistance against movement of the handle from a first rotational position to a second rotational position.

12. A manual valve actuator according to claim 1 in combination with a medical fluid delivery set, the medical fluid delivery set comprising:

tubing adapted for fluid flow therethrough,

the valve mechanism in fluid communication with the tubing, the valve rotor of the valve mechanism adapted to engage a flow control apparatus for manipulation of the valve mechanism by the flow control apparatus.

13. A manual valve actuator and medical fluid delivery set according to claim 12 wherein the valve mechanism comprises a valve housing having an inlet, an outlet and a chamber, the inlet being in communication with the outlet through the chamber to permit fluid flow through the valve mechanism, and a valve rotor disposed in said chamber, the valve rotor being adapted to operatively engage the valve driver of the manual valve actuator when received in the holder.

14. A manual valve actuator for a medical fluid delivery set including a valve mechanism having a valve rotor capable of regulating a flow of fluid through the valve mechanism, the manual valve actuator comprising:

a holder separate from the valve mechanism and comprising a ring and a pocket connected to the ring adapted to removably receive the valve mechanism such that removal of the valve mechanism from the holder does not prevent the valve mechanism from regulating fluid flow through the valve mechanism, the holder being shaped to hold the valve mechanism against rotation with respect to the holder;

a valve driver rotatably disposed within a central opening of the ring, the valve driver being sized and shaped for reception into a recess defined in the valve rotor, the valve driver projecting into the holder so that the valve driver engages the valve rotor in the recess when the valve mechanism is received in the holder;

a handle operatively connected to the valve driver for rotating the valve driver and thereby the valve rotor when the valve mechanism is received in the holder, the handle being annular with a central opening, the ring of the holder being disposed within the central opening; and

a lock positioned with respect to the holder to engage the valve mechanism to prevent removal of the valve mechanism from the holder whenever the valve rotor is in a rotational position permitting fluid flow through the valve mechanism, the lock being moveable to a position to permit removal of the valve mechanism from the holder when the valve rotor is in a rotation position preventing fluid flow through the valve mechanism.

15. A manual valve actuator according to claim 1 , wherein the holder comprises a pocket adapted to removably receive the valve mechanism, the pocket having an open top positioned to receive the valve mechanism into the pocket passing through the open top in a direction perpendicular to the axis of rotation of the valve driver.

16. A manual valve actuator according to claim 1 , wherein disengagement of the valve mechanism from the valve driver does not prevent the valve mechanism from regulating flow through the valve mechanism.
