Comar Plastic Oral Syringes – Unique Two-Piece Design for Patient Safety

The Comar Oral Syringe is a two-piece dispenser that uses a patented wiper design, instead of a rubber grommet, to form a complete seal between the plunger and the barrel. Removing those small siliconized rubber parts from the tip of the syringe greatly reduces the risk of choking and project contamination. Comar oral syringes are ideally suited for safely dispensing medication or applying topical applications.

In April 2016, the FDA released its Guidance for Industry on “Safety Considerations for Product Design to Minimize Medication Errors.” The document refers to an estimated 7,000 deaths occurring each year as a result of medication errors. Medications now exceed household products, such as cleaning fluids, as the primary cause of pediatric poisoning. To develop preventive strategies, the U.S. Centers for Disease Control and Prevention (CDC) formed the PROTECT Initiative bringing healthcare professionals together with leading over-the-counter medication and packaging manufacturers. Comar, an original member of the PROTECT Initiative, developed the DoseGuard® system in response. Comar’s oral syringes combined with the new DoseGuard, offer maximum liquid dispensing safety.

We manufacture stock and made-to-order Oral Syringes, Valved Bottle Adapter Systems, Oral Syringe Bottle Adapters (Orifice Reducers), and Oral Syringe Tip Caps.

Oral Syringe Accessories

Press-In Bottle Adapters (Orifice Reducers)

Press-in bottle adapters allow for increased dosing accuracy when filling oral syringes. Available in various sizes, they fit securely in any bottle with a corresponding opening size. The adapters allow a user to easily draw liquid with an oral syringe, ensuring accurate dosing while avoiding spills; they fit flush with the bottle opening so that the original cap can be placed on the bottle.

Features & Options

  • Vented or Non-Vented: Vented adapters can be used where large doses coupled with low head-space may create a vacuum inside the container. The vent allows air into the bottle as a dose is extracted.
  • Sizes: 20 mm, 24 mm, 28 mm, and 33 mm
  • Easy, spill-free prefilling of oral syringes
  • Innovative design works with plastic bottles
  • Low profile allows use of standard closure to seal bottle
  • CE mark for European markets available upon request
  • Material: LDPE (low-density polyethylene)

DoseGuard® Valved Bottle Adapters

Comar designed the DoseGuard® to improve on traditional bottle adapters that simply act as open-flow restrictors. Our design employs a passive valve to provide closed flow control thereby keeping liquid medications child-safe. The DoseGuard® has been recognized for its proven ability to protect children from an accidental overdose of liquid medications and is compatible with standard containers and oral syringes. The improved flexibility of DoseGuard® allows it to more easily integrate with packaging lines, and gives manufacturers of liquid over-the-counter and prescription medications an additional means to comply with the U.S. Centers for Disease Control and Prevention (CDC)  PROTECT Initiative.

Features & Options

  • Sizes: 20 mm, 24 mm, and 28 mm
  • Works with standard plastic bottles
  • Securely connects to container finish are rests on top of the finish, this low profile allows for use of a standard closure
  • Patented valve design remains closed until the tip of the oral syringe is inserted into the valve
  • Valve opening is customizable to specific product viscosity and is easily adaptable to an open-hole flow restrictor for use with products requiring dosage cups
  • Single material one-piece construction reduces contamination risks
  • Material: LDPE (low-density polyethylene)

Oral Syringe Tip Caps and Stands

  • Standard Tip Cap snaps on and seals the syringe tip
  • Self-righting tip cap version is available to keep the cap clean
  • Standard colors: White, Blue, and Natural
