Abstract:

Two new experimental dialyzers were designed which employ the cone membrane support. The first is a 16 parallel tube device of 1.4 sq. M surface area in which flow is crosscurrent. The second consists of a variable number of rigid discs which define countercurrent radial flow paths for blood and dialyzing fluid. Adjacent discs are held in position by interlocking, rigid peripheral rings and seals are effected by peripheral elastomeric O-rings. The cone support was also modified for the membrane blood oxygenerator, on the basis of preliminary studies which showed marked improvement in CO2 transport. Vexar, a new plastic mesh, was evaluated as a membrane support for disposable coil dialyzers. It was found to be an effective turbulence promoter and is expected to allow higher blood flow with less pressure drop. A new blood pump is under construction. It consists of three parallel, compressible tubes with integral balland-check valves at either end. Author
