Patent ID: 7347865

Claim:
An ear duct cleaning device, comprising: a flexible tubular member equipped at one end with an inflatable element and at its opposite end with means of supplying a fluid at a certain pressure, where said inflatable element is coupled to means of controlling the inflation in a manner so that said inflatable element assumes, once inflated, a shape such that its radial extension with respect to the axis of said tubular member is considerably greater than that along the same axis, said means of controlling the inflation of said inflatable element comprising means of limiting the extension of said inflatable element in the direction of the axis of said tubular member, and said means of limiting the extension of said inflatable element in the direction of the axis of said tubular member comprises a tubular element, said inflatable element is slipped over, while sliding longitudinally in a sealed manner inside said tubular member, coaxially and concentrically to the same, wherein an end toward the outside of said tubular element carries means of blocking said inflatable element, while means are provided on the lateral wall of said tubular element for arresting the motion of the same, which are placed at a given distance from the end of the tubular element that said inflatable element is fitted upon, and are co-operating with the means of blocking present on the internal wall of said tubular member, wherein said tubular element maintains a continuity of fluid communication between said inflatable element and said means of supplying fluid at a given pressure.
