Abstract:
A tubing sealer for sealing fluid filled tubing, said tubing sealer comprising in combination:a) a housing having a base, a cover and brackets disposed within said housing for delineating three compartments within said housing; b) a solenoid assembly disposed in one of said compartments; c) a circuit board disposed in another of said compartments for providing a source of RF energy and for actuating said solenoid assembly; d) a power supply disposed in yet another of said compartments for providing electrical power to said solenoid assembly and to said circuit board; e) a face plate secured to said housing for supporting a fixed jaw; f) an electrically grounded movable jaw adapted for rectilinear translation in response to actuation of said solenoid assembly to squeeze a length of tubing against said fixed jaw; g) a switch for actuating said circuit board to energize said solenoid assembly and to transmit RF energy at a predetermined frequency from said fixed jaw through the tubing to said movable jaw and heat the tubing to form a welded seal; and h) a source of air flow directed through each of said compartments, including a plurality of apertures disposed in components of said housing for conveying the air flow, each aperture of said plurality of apertures being configured to inhibit spurious and unauthorized transmission therethrough of RF energy at other then the predetermined frequency.
