Patent ID: 8821719

Claim:
A medical device which is connectable to a water line for the supply of water or prepared water into the medical device, containing an adapter which comprises a first supply line section ( 4 ) with a terminal coupling member ( 1 ) for connection to the water line ( 3 ), said terminal coupling member being a quick-action coupling member, with a downstream pressure sensor ( 20 ) connected to said first supply line section ( 4 ) and with two downstream, successively arranged shut-off valves ( 5 , 6 ) connected to said first supply line section ( 4 ) next to said downstream pressure sensor ( 20 ), wherein said pressure sensor ( 20 ) is located with said terminal coupling member ( 1 ) located on one side and said two shut off valves ( 5 , 6 ) are located on the opposite side of the pressure sensor ( 20 ) in series, and two second supply line sections ( 8 , 9 ) which branch off from the first supply line section ( 4 ) by means of a branching member ( 7 ) which is connected to said first supply line section ( 4 ) after said shut-off valve ( 5 , 6 ), wherein one of the second supply line sections ( 8 ) is connected via a connection ( 10 ) to a permeate inlet line ( 11 ) of the medical device that terminates in a feed container ( 12 ), and the other one of the second supply line sections ( 9 ) is connected via a connection ( 13 ) and a shut-off valve ( 16 ) to another fluid line ( 15 ) of the medical device into which a shut-off valve ( 17 ) is inserted and which also terminates in the feed container ( 12 ), wherein disinfection fluid can flow through the other fluid line ( 15 ) in a disinfecting process and the shut-off valves ( 16 and 17 ) are alternatingly switchable, so that disinfection fluid is alternately circulating through the fluid line ( 15 ) into the feed container ( 12 ) and through the second supply line sections ( 8 , 9 ) and the permeate inlet line ( 11 ) into the feed container ( 12 ).
