Access system for a medical treatment device for extracting or adding a medical liquid, and medical treatment device having an access of this kind

Abstract

The invention relates to an access system P for a medical treatment device, in particular an extracorporeal blood treatment apparatus 1. The invention also relates to a medical treatment device, in particular an extracorporeal blood treatment apparatus 1, comprising such an access system P. The access system according to the invention has a housing body 20 which comprises an outer housing part 21 that is hollow on the inside and that is formed a connection piece 26 for connecting a closure part 36 for the fluid-tight closure of the access system or for connecting a connector 27. The access system is characterised in that a UV irradiation unit 30 is provided for emitting ultraviolet light, which comprises a plurality of UV light-emitting diodes 32 emitting ultraviolet light or an annular UV fluorescent tube, the outer housing part 21 having a region which is permeable to ultraviolet light. The UV light-emitting diodes 32 or the annular UV fluorescent tube are arranged in such a way that the ultraviolet light passes through the region of the outer housing part 21 that is permeable to ultraviolet light and enters the interior of the access system.
