Drug Delivery Reservoirs

Deliver accurate and consistent doses

POREX® drug delivery reservoirs can be loaded with pharmaceutical agents and incorporated into a drug delivery device. Reservoirs can be developed from porous polymer or porous fiber materials, depending on the design and functional performance requirements of the reservoir.  

Our drug delivery reservoirs:

  • Optimize dosage accuracy–Both porous plastic and porous fiber materials are engineered for dosage accuracy and structural integrity.
  • Deliver consistent drug dose release- Optimized for loading and absorption of the drug into the porous material for statistical consistency of drug dose release, as well as for air flow and chemical resistance.
  • Accommodate varied device requirements through customized part geometries.

Oral Inhaler Filters

Ensure metered dose integrity and accuracy in oral inhalers

Customized POREX® inhaler filters are used in metered dose inhalers to deliver measured amounts of pharmaceutical agents to patients via oral-bronchial administration. With the added ability for customization to promote preservative-free packaging, our oral inhaler filters:

  • Deliver accurate doses in metered dose inhalers–Customized inhaler filters facilitate the delivery of measured amounts of pharmaceutical agents specific to the device’s design requirements.
  • Protects inhaler's mechanical systems from obstruction, thereby enhancing performance.
  • Can be customized based on device requirements by optimizing for pore size, airflow and dimensional tolerances.

Nasal Inhaler and Spray Pump Filters

Deliver precise doses while minimizing contamination in nasal inhalers

Pharmaceutical and healthcare companies rely on Porex for customized antimicrobial filtering solutions for nasal inhalers and spray pumps. POREX® filters are designed to prevent contamination of the pharmaceutical agent.

Our nasal inhaler and spray pump filters:

  • Facilitate cleaning filtration–Porous materials ensure pharmaceutical agent is free of contamination.
  • Deliver preservative-free packaging–Antimicrobial additives in the structure of porous material helps maintain the sterility of the pharmaceutical agent.
  • Offer optimized air flow performance as specified by the functional requirements of the specific device.

Nebulizer Filters and Vents

Minimize contamination and noise of nebulizers

POREX® nebulizer filters and vents offer a two-fold advantage when assembled into a nebulizer, a device that converts liquid into an aerosol for inhalation of medication. Our porous materials effectively filter or vent the air as it is drawn into the device through the air inlets, keeping out particulates, microbes and other contaminants. In addition, these filters also act to muffle the noise created by the action of the device.

Specifically designed for nebulizers, our filters and vents:

  • Assure easy assembly–Designed for ease of assembly into the nebulizer, these three-dimensional molded part designs are inherently strong, creating a better seal than traditional fiber filters when press-fit into nebulizer devices.
  • Reduce contamination–Effectively filter or vent air as it is drawn into the device through the air inlets, keeping out particulates, microbes and other contaminants.
  • Offer a better user experience– Diffuse sound by muffling noise created by nebulizers during use.

Topical Applicator Filters and Wicks

Improve application of wound sealing agents

POREX® topical applicator filters and wicks are designed for fluid-based application of sealing agents for wound closure, such as surgical adhesive or drug delivery in dental treatment applications, and can also serve as a filter if the solutions are mixed and expressed from crushed glass ampoules.

Designed to provide maximum performance for topical applicators, our filters and wicks:

  • Deliver optimal wicking rates–Design provides optimal wicking rates of the liquid adhesive from the reservoir to the tip surface, which is then used as the applicator.
  • Deliver precise application – POREX topical applicator tips provide specified lay-down of the liquid adhesive to the wound surface.
  • Ensure appropriate press-fit seal and manufacturability–Filter strength and pliability ensures appropriate seal between the filter applicator and the device’s exterior barrel, and also allows for automated assembly processes and sterilization via gamma or ethylene oxide (EtO) processing.

Infusion Therapy Set Filters and Vents

Balance performance and protection for optimal infusion therapy

POREX® infusion therapy set filters and vents provide the perfect balance of performance and protection for optimal infusion therapy with reduced risk of infection.

Critical components of our infusion therapy solutions include:

  • POREX® spike vents -  Complete efficient delivery of the dose solution without impacting the physical stability or introduction of microbes or foreign matter, thereby protecting the medical professional from infection and drug exposure.
  • POREX® in-line filters - Hydrophilic membrane protects against accidental air intrusion into the infusion line.
  • POREX® primer vent - Hydrophobic membrane with 1.2 micron pore size that allows air to pass through but stops fluid and provides a barrier to contact contamination.
