Advanced Venting for Wearable Injectable Devices

Wearable Vents for Injectable Medical Devices

Injectable medical devices require vents for several essential reasons that contribute to maintaining a sterile environment and enhancing the performance of these devices. One of the primary reasons for incorporating vents is to prevent the buildup of pressure during the injection process. This pressure buildup can lead to inaccuracies in the administration of medications.

Our optimized wearable vents are designed to maintain pressure balance during medication administration, ensuring accurate dosing and preventing cross-contamination. With enhanced safety features, customizable designs, and compatibility with sterilization processes, our vents provide reliable protection and sample integrity. Explore our range of wearable venting solutions for optimized drug delivery in wearable medical devices.

Options for standard and custom venting options for wearable devices

Key Features & Benefits

    • High airflow venting: Vents allow gases to escape at high airflow under arterial pressure.

    • Customizable designs: Vent designs can be tailored to integrate into syringes and accommodate high-volume automated assembly.

    • Sample integrity: The vent’s self-sealing ability preserves samples in a controlled environment.

    • Sterilization compatibility: Our arterial syringe vents are compatible with gamma, e-beam, and ethylene oxide (EtO) sterilization processes.

    • PFOA-free: Compliant with (EC) 1907/2006 REACH / Regulation (EU) 2019/1021 POP.
