DIALYZERS AND METHOD FOR MODIFYING THE SAME USING A LASER |
摘要 |
The invention relates to laser technology and dialyzers, and to a method for modifying said dialyzers. The aim of the invention is to reduce the stop periods during the processing of the dialyzer ends and to obtain a flat surface on the dialyzer ends. To this end, the hollow membrane ends (5) of the inventive dialyzer are funnel-shaped in the entry and exit areas in the area of the plastic embedding (2), have rounded-off edges and have a smooth, melted and cleaned surface (4) with the plastic (2). According to the inventive method for producing a dialyzer, a surface working process is carried out using a pulsed laser beam (6) in the mid-infrared range at least instead of the final precision cut. |
