Abstract:
A tranducer-protector device for biomedical heamodialysis lines, comprising a first tubular connector of the female Luer Lock type with a conical inner surface and an outer threading, intended to be connected to a tube of a haemodialysis equipment, a second tubular connector coaxial to said first tubular connector, said first and second tubular connectors being provided with respective first and second radial annular flanges for their mutual permanent sealed connection by ultrasonic welding, and a filtering membrane made of a permeable material defining an anti-contamination sterile barrier interposed transversely between said first and said second tubular connectors and having a peripheral edge clamped between said radial annular flanges, wherein said second tubular connector with said second radial annular flange is formed by one piece of high rigidity moulded thermoplastic material, and wherein said first Luer Lock connector with said first radial annular flange is constituted by one piece of a moulded thermoplastic material having elasticity characteristics higher than those of said second tubular connector with said second radial annular flange.
