ABSTRACT:
Apparatus for controlling a fluid flow includes a housing having a first fitting for connection of a tube and at least one further fitting for detachable securement of a coupling piece of a peritoneal catheter. Accommodated in the housing is a rotary valve which is indexable in predetermined positions to selectively establish a fluid communication between the fittings. Associated with one of the fittings is at least one closure member which is acted upon by the rotary valve for displacement in a radial direction to open and close a passage to the peritoneal catheter.
