摘要:
A device for the diffusion of substances between two fluids via semipermeable membranes (2), which are arranged in a stack separated by spacer plates (1), which on their surfaces are provided with ducts (18,35) connected to the inlets and outlets (4-7) for at least one of the said fluids, these spacer plates (1) being arranged in the folds of one or more membranes (2) folded in zigzag. The device is characterised by two transverse ducts (18) arranged near two opposite front edges (17) of the plates (1) substantially parallel with these front edges (17), which open onto at least one of the lateral edges (24), which connect the front edges (17) of the plates (1). The device is intended to be used as a so-called artificial kidney, where the said fluids consist of blood and of dialysis liquid respectively.

摘要:
A coupling comprising two mating coupling pieces (15a, 16a) for the connecting of two flexible tubes (12a, 20a) or the like. The coupling is characterized in that at least one coupling piece (15, 15a, 15b, 15c) is composed of two or more components (21a, 22a, 28a; 21b, 22b, 28b; 21c, 22c, 28c) of material of different rigidity which together withstand autoclaving. The coupling in accordance with the invention is Intended first and foremost to be used in conjunction with a method of treatment known under the name of CAPD (Continuous Ambulatory Peritoneal Dialysis). The coupling is preferably designed to comprise a readily penetrable membrane and a protective cover which can readily be torn off.
