The present invention relates to a continuous process for preparing permselective hollow fiber membranes being suitable e.g. for hemodialysis, hemodiafiltration and hemofiltration of blood which comprises a two-stage drying and tempering treatment of the hollow fiber membranes. According to a further aspect, the invention relates to a continuous process for drying permselective hollow fiber membranes on-line. The invention also relates to devices for on-line drying of permselective hollow fiber membranes.

On-line drying of hollow fiber membranes

The present disclosure relates to capillary dialyzers for blood purification comprising from 85-95% crimped fibers and from 5-15% non-crimped fibers.

Capillary dialyzers

An end cap for a pressure vessel has at least one part for connecting the end cap to a housing. The at least one part comprises a number of recesses. The recesses are arranged to form at least one fluid passage between an inside and an outside of the end cap when the end cap is plugged on the housing. A housing for a pressure vessel has at least one counterpart for connecting an end cap to the housing by engaging a part of the end cap. The at least one counterpart comprises a number of recesses. The recesses are arranged to form at least one fluid passage between an inside and an outside of the housing when the end cap is plugged on the housing. A method for leak testing a pressure vessel and a method for checking a connection between at least one end cap and a housing of a pressure vessel for leak tightness are also described.

Leak testing of a pressure vessel

A machine () for extracorporeal blood treatment comprises a device () for ultrafiltration of a liquid through a semi-permeable membrane () of a blood treatment device (), a first sensor () for ultrafiltration rate through the membrane, a second group of sensors () for measuring a trans-membrane pressure, an infusion line () with an infusion pump () and a programmed controller () for calculating a maximum infusion rate as a function of the transmembrane pressure. The machine is suitable for kidney failure treatments, such as hemofiltration and hemodiafiltration. In a relatively short time the machine enables a large quantity of corporeal blood to be removed from the patient.

Machine and procedure for extracorporeal treatment of blood

Arrangement for extracorporeal circulation of blood having a generally uniform flow diameter where the risk for stagnation of blood is avoided or reduced. The arrangement comprises a generally circular cylindrical means for temporary expanding the flow diameter, a means for flow expansion (). The means for flow expansion () is arranged connecting the bloodline () and a component () for circulation of the blood. The means for flow expansion () comprises a first part with a first flow diameter, dand a second part downstream the first part with a second flow diameter dwhere d/d&#x2267;1.5. The first part has a length extension Land the second part has a length extension Lwhere L/L&#x2267;0.5.
