Abstract: A coupling member for joining a male member and a female member of a hearing aid device or a hearing diagnosis device is disclosed. The coupling member comprises a male member that comprises two or more annular ribs extending radially from a pipe member having a distal end. The female member comprises a number of cavities configured to receive and contain the annular ribs of the male member. The height of the annular ribs increases as function of the distance from the annular ribs to the distal end of the pipe member.

Abstract: In order to measure the degree of filling of a dust collector (5), where the dust (15, 16) collected in the dust collector may be of a very varied composition ranging from very fine dust (15) to rather large particles (16), a high pressure difference and a low pressure difference are measured by two differential pressure meters (11, 12), where the one differential pressure meter (12) measures the pressure difference between the compartment (4) of the dust collector, in which the dust collector (5) is arranged, and a measurement position at the connecting stub (6) of the vacuum cleaner, as is known, while the other differential pressure meter (11) measures between two measurement positions inside the connecting stub (6).
