Fluid flow control valve and transfer set
First Claim
1. A multi-position mechanical apparatus for controlling fluid flow within a fluid transfer device having multiple, interconnected flexible, conduits normally open for fluid flow therethrough, the apparatus comprising:
- a base member for receiving a plurality of the interconnected fluid flow conduits; and
selecting means, including a rotatable member rotatable in only one direction, said selecting means removably affixable to said base member and supported movably by said base member for selectively blocking fluid flow through at least one of the members of the plurality of flexible fluid flow conduits, said selecting means being affixable to said base member only at a single rotational insertion/removal position.

Abstract
A multi-position rotary valve system is useable with a disposable fluid transfer set for carrying out a sequence of steps to implement a drain and fill procedure in connection with peritoneal dialysis. A method of carrying out peritoneal dialysis includes utilizing a rotary, multi-position, valve system in conjunction with a fluid flow transfer set having a plurality of flexible fluid flow conduits. The valve system provides for systematically opening and closing the respective fluid flow conduits in a predetermined sequence for the purpose of carrying out a drain and fill procedure of the type associated with peritoneal dialysis.

34. A multi-position rotary valve for controlling fluid flow within a fluid transfer device having multiple, interconnected, flexible conduits normally open for fluid flow therethrough, the rotary valve comprising:
-
a base member for receiving a plurality of interconnected fluid flow conduits; and selecting means removably, and rotatably mountable on said base member for clamping shut selected of the fluid flow conduits with said selecting means defining at least one rotatably movable valve opening for unclamping selected of the fluid flow conduits and, permitting a flow of fluid therethrough as said selecting means is rotated, said selection means being rotatable in only one direction and mountable on said base only at a single rotational insertion/removal position. - View Dependent Claims (35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47)
