Abstract
A transducer protection device, particularly for hemodialysis processes, which comprises a first element and a second element made of plastics which are coupled coaxially with respect to a common axis and respectively comprise a first tubular connector and a second tubular connector which are blended with respective flanges which are coaxial to the common axis; the flanges are coupled to each other along their peripheral region by ultrasonic thermal bonding; the device has a recess formed frontally on a first one of the flanges, the recess being coaxial to the common axis and being suitable for accommodating, in a fixed arrangement, a semipermeable membrane by imbibition of melted plastics along a circular border region by the thermal bonding provided on a circular ridge which is shaped complementarily to the border region and protrudes frontally from the second flange so as to achieve bonding between the first and second flanges and the membrane.
