Transducer protectors are used in hemodialysis blood lines to keep the blood side of the circuit separated from the machine side, and to prevent contamination of the machine by the blood flowing through the circuit. This contamination could be very dangerous and can lead to patient cross contamination with hepatitis B or other virus. Transducer protectors let air pass while preventing the blood from passing through. TP's incorporate bacterial retentive membrane (0.2µm, if not otherwise requested).
Membrane Solutions transducer protectors are also suitable as air or gas vents. Venting characteristics are achieved by using hydrophobic membranes. Membrane Solutions has a full range of transducer protector products which incorporate either highly hydrophobic PTFE or hydrophobic acrylic membranes, and custom products can be manufatured upon request.
