The internal cleaning device has a rod. The internal cleaning device has a rod with a rod end region and a rod start region. For reliably cleaning the tone holes of the corresponding wind instrument, a central channel sealing device is formed at the end region and a central channel insert or attachment is formed at the rod start region. The central channel insert or attachment has at least one fluid passage opening and/or the rod is a tube open at the rod start region and closed at the rod end region. A peripheral wall of the tube is formed with at least one tube opening. ## Claims ### Claim 1 An internal cleaning device for a wind instrument that is formed with a central channel and at least one tone hole which opens into the central channel, the internal cleaning device comprising: a rod having a rod start region and a rod end region; a central channel sealing device disposed at said rod end region of said rod; a central channel holder formed on or around said rod start region of said rod; and said central channel holder being formed with at least one fluid passage opening; and/or said rod being a tube that is open at said rod start region and closed at said rod end region, and said tube having a peripheral wall formed with at least one tube opening. ### Claim 2 (depends on 1) The internal cleaning device according to claim 1, wherein said central channel sealing device is a rubber or silicone collar. ### Claim 3 (depends on 1) The internal cleaning device according to claim 1, wherein said central channel sealing device comprises an umbrella and an opening and closing mechanism for said umbrella. ### Claim 4 (depends on 1) The internal cleaning device according to claim 1, wherein said central channel sealing device is an inflatable balloon that is configured to be emptied by suction. ### Claim 5 (depends on 1) The internal cleaning device according to claim 1, wherein said at least one tube opening is an elongated slot. ### Claim 6 (depends on 1) The internal cleaning device according to claim 1, wherein a blowing or pumping device is arranged on a blowing or pumping opening formed in said central channel holder. ### Claim 7 (depends on 6) The internal cleaning device according to claim 6, wherein said blowing or pumping device is selected from the group consisting of a balloon pump, a piston pump, and a bellows. ### Claim 8 (depends on 1) The internal cleaning device according to claim 1, wherein said central channel holder is a rotary part with a rod receptacle and an insertion sleeve overlapping said rod receptacle, and wherein said at least one fluid passage opening is formed between said insertion sleeve and said rod receptacle. ### Claim 9 (depends on 8) The internal cleaning device according to claim 8, which comprises an attachment bell formed around said insertion sleeve. ### Claim 10 (depends on 1) The internal cleaning device according to claim 1, wherein said central channel holder is an insert plug or an attachment cuff, and said tube in which said at least one tube opening is formed passes through said insert plug or said attachment cuff. ### Claim 11 (depends on 1) The internal cleaning device according to claim 1, wherein said rod is formed from carbon.
