Abstract: A holding frame for connector includes different latch and spring elements on opposite side walls of a base frame attached and project with their respective guiding portion whose T- or L-shaped post. The guiding portion ensures through its catching funnel for a comfortable insertion of the connector modules in the correct polarization and thereby, and while holding the then in the holding frame latched connector modules, stabilizing the post. In the construction of the holding frame is a permutation of various latch and spring elements on the base frame by an interaction of their fixing contour with a fixing contour of the respective side wall of the base frame prevented. Due to the special shape of the latch and spring elements, a cable connection-side removal of a connector module is possible if the holding frame is already installed in a commercially available attachment housing.

Abstract: The present invention discloses a method for preparing an anti-bacterial surface on a medical material surface, including the steps of: (1) conducting chemical graft of amino silane after performing oxygen plasma pretreatment to the medical material surface and then reacting the medical material with the amino silane surface with an acyl compound; (2) placing the medical material with an initiator-modified surface into an anti-adhesion monomer aqueous solution for a graft polymerization reaction; (3) placing the medical material with an anti-adhesion polymer brush-modified surface into an azide compound-containing dimethylformamide solution; and (4) placing the medical material with an azide surface into an anti-bacterial agent click solution for a click reaction, obtaining an anti-adhesion polymer layer—and anti-bacterial agent layer-comodified anti-bacterial surface.
