A connecting system is claimed for the two separate parts of a medical system. The surfaces in contact form a firm and well-sealed connection with each other, by heat-treatment of the contacted surfaces, followed by cooling. The contact surface of one part comprises plastic material which contains at least one polymer which is dimensionally stable at the temp. of heat-treatment. The other comprises plastic material which tends to flow under a compressive force at the heat treatment temp. Neither plastic material contains any PVC or EVA. Also claimed is a process for connecting the two separate parts of a medical system as above, by bringing surfaces together to form a connecting arrangement, with the formation of a contact area defined by the touching parts of the parts, then the assembled connecting arrangement is heat-treated to form a firm, well-sealed connection, and cooled. |
