Transducer Protectors Characteristics

Range of application
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).

Transducer protectors must guarantee a sufficient air flow to provide immediate reaction time if there is a change in patient blood pressure. If the TP does not react quickly enough, this can be very dangerous for the patient.
GVS transducer protectors are also suitable as air or gas vents. Venting characteristics are achieved by using hydrophobic membranes. GVS 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.
 

 
Manufacturing technology
GVS transducer protectors are manufactured with fully automated assembly technology, and the sealing is done without any glues or solvents - they are ultrasonically welded. Automatic testing machines keep the manufacturing process consistent and guarantee superior quality.

Wide choice
There are several models listed below which enable customers to find the suitable product for the intended application. We use a variety of housing resins for different applications and sterilization methods. The wide range of standard available media (PTFE or acrylic membranes) provides high flexibility and covers almost any requirement of the market.
Because of our wide choice of shapes (Flat TP, TP "bell" shape and TP "dome") and the very different types of materials and media used, the GVS transducer protector line is suitable in any blood line or other medical devices.
Available membrane sizes are from 0.02 to 10 micron. Pressure isolator with flexible diaphragm are suitable for open heart surgery.

 

 
Assembly method
The available connections are Female Luer Lock, , Male Luer Lock and Male Slip Luer. They can be assembled or bonded (standard with cyclohexanone, cyanoacrylate and methylethylketone).

Bacterial / Virus retention 
Our transducer protectors equipped with membranes 0.2 µm to 3 µm can be considered bacterial retentive.

Biocompatibility
GVS transducer protectors comply with the ISO 10993 standard for external communicating device - blood path indirect - prolonged contact duration.

Drug compatibility
Our 25mm products have low protein binding characteristics that ensure minimal adsorption of drugs and they have proven bacterial retention. Drug compatibility depends on membrane used.
