Abstract
An apparatus for the transmission of the pressure in the sterile area of a medical appliance, such as a hemodialysis appliance, to a non-sterile pressure gauge having two housing halves and a sterility filter positioned between the two housing halves. The housing half on the sterile side may be made of polycarbonate, and the non-sterile housing half may be made of a polymer, preferably a polyester/polyether copolymer, which provides an easily disconnectable and leak-proof connection with the pressure gauge. The two halves are ultrasonically welded together.
