Abstract
An external support that routes the tubing of a reversing valve in such a manner that connection tubes extend from one end of the device and the treatment device tubes extend from the opposite end. The external support may provide guides that hold the tubing extending from the supported flat rotary switch type of valve so as to keep them from being pinch or kinked thereby ensuring free flow of blood.
