Patent ID: 7475697

Claim:
A cleaning device using cleaning water to clean both channels of a medical instrument including a first channel and second channel and a portion via which both the channels are connected to each other, comprising: a tubular member including a proximate-end portion and a distal-end portion which able to be inserted in an inlet of the first channel of the medical instrument; a first water supply port which is disposed in the distal-end portion and which leads to the first channel to supply the cleaning water to the first channel, when the distal-end portion is inserted in the inlet; a first seal member which is disposed on an outer peripheral surface of the distal-end portion and which is positioned and disposed on a proximate-end side from the water supply port to seal a gap between an outer peripheral portion of the distal-end portion and an inner surface of the first channel and to constitute a first engaging portion which attaches the distal-end portion inserted in the inlet to the medical instrument, when the distal-end portion is inserted in the inlet; a second water supply port which is disposed in the tubular member and which is positioned and disposed in a proximate-end side portion partitioned from the first water supply port by the first seal member when the distal-end portion is inserted in the inlet and which leads to the second channel to supply the cleaning water to the second channel; a second engaging portion which is disposed in the tubular member and which is positioned and disposed on the proximate-end side from the second water supply port and which is constituted by an outer peripheral portion sealing from a seal member of the medical instrument, when the distal-end portion is inserted in the inlet; a first inlet port which is disposed in the proximate-end portion of the tubular member and which is connected to the first water supply port and which is to be connected to a water supply source of the cleaning water; and a second inlet port which is disposed in the proximate-end portion of the tubular member and which is connected to the second water supply port and which is to be connected to the water supply source of the cleaning water.
