| 摘要 |
Transducer-protector device for biomedical haemodialysis lines, comprising a first tubular connector of the female Luer Lock type and a second tubular connector which are coaxial to each other and provided with a first and a second annular radial flange, respectively, for their mutual permanent sealed connection by ultrasonic welding, and a filtering membrane interposed and clamped between the first and second annular flanges. The second tubular connector with the second annular flange is formed in one piece of high rigidity molded thermoplastic material, while the first tubular connector with the first annular flange is formed in one piece of a molded thermoplastic material having higher elasticity characteristics, conveniently selected in the class of polybutylenterephthalate polymers. |
