Transducer-protector device (1) for biomedicalnhaemodialysis lines, comprising a first tubularnconnector of the female Luer Lock type (2) and a secondntubular connector (3) which are coaxial to each othernand provided with a first and a second annular radialnflange (4,5), respectively, for their mutual permanentnsealed connection by ultrasonic welding, and anfiltering membrane (6) interposed and clamped betweennthe first and second annular flanges (4,5). The secondntubular connector (3) with the second annular flangen(5) is formed in one piece of high rigidity mouldednthermoplastic material, while the first tubularnconnector (2) with the first annular flange (4) isnformed in one piece of a moulded thermoplastic materialnhaving higher elasticity characteristics, convenientlynselected in the class of polybutylenterephthalatenpolymers. |
