Oxyphen’s track-etched membrane solution offer reliable venting and sterility control while also providing effective pressure equalization.

Medical devices need to be able to accurately and precisely deliver fluids, including liquids and gases, in an effort to ensure the medication is delivered safely, reliably, and comfortably to the patient. The device needs a variety of safety features, including a venting membrane which relieves pressure, protects the device from external contamination, and prevents blockage from occurring.

For example, the treatment of diabetes requires a defined insulin dosage, often time administered by the patient themselves via subcutaneous injection. If blockage occurs within the insulin pump, too much insulin may be delivered to the patient which can be dangerous. Infusion devices must be protected from blockage during the filling of the tube or during the priming of the tube. When an infusion pump malfunctions, it can cause the patient to suffer acute hypoglycemia, a severe and potentially fatal medical condition. 

Oxyphen’s track-etched membrane solutions offer reliable venting and sterility control with water and dust tight protection that will eliminate the ingress of contaminants such as oil, solvents, or other low surface energy liquids while also providing effective pressure equalization.

  • Reliable venting and sterility control 
  • Water-tight protection 
  • Protection against oils, solvents and other low-surface energy liquids 
  • Dust tight protection 
  • Effective pressure equalization 
  • Easy mounting with ultrasonic welding by rollstock application 
  • Gamma- and X-ray stable solution for easy and reliable sterilization 
  • 100% Free of PFOA: Compliant with (EC) 1907/2006 REACH / Regulation (EU) 2019/1021 POP

Highlighted Case Study

Electronic Textiles

Oxmotex AG is a research and development company dedicated to electroosmotic vapor and fluid transport, who developed revolutionary proprietary technology for electronically controlled moisture transport in membranes and textiles. As they looked to create a new innovative technology that would provide active electronically driven moisture transport, they came to Oxyphen for a track-etched membrane solution that would be responsive to changing climates, transport moisture beyond normal sweat rates, and be comfortable for the wearer.
