Low Dead Space Injection Syringe 3ml integrates an extended plunger tip that fills the internal nozzle cavity, reducing fluid residual volume to ≤ 0.005 ml after injection. Manufactured from medical-grade polypropylene with dosage markings compliant with ISO 7886-1, it serves healthcare importers, hospital supply distributors, and pharmaceutical packagers seeking reduced medication waste in clinical, immunization, and therapeutic applications.

Key Features

Extended Plunger Tip: Fills the internal space of the syringe nozzle hub to minimize fluid retention upon full stroke.

Polypropylene Barrel: Provides optical clarity for visual detection of fluid levels and air bubbles.

ISO-Compliant Graduation Scale: Printed with solvent-resistant ink according to ISO 7886-1 to maintain scale legibility during clinical handling.

Latex-Free Synthetic Gasket: Seals under positive pressure while providing consistent gliding resistance without natural rubber latex.

Universal Luer Fitting: Connects directly with standard hypodermic needles and clinical injection accessories.

Design and Construction

Hub-Filling Geometry

The molded plunger extension corresponds to the internal volume of the syringe neck to push out liquid that typically remains in standard hubs.

Barrel Retaining Lip

An internal rim at the rear of the barrel prevents accidental plunger displacement during liquid draw.

Flange Grip Area

Extended top flange structure offers finger placement support during manual depression.

Intended Use and Applications

Vaccine Dosing: Minimizes fluid loss per injection cycle, supporting dose extraction efficiency from multi-dose or single-dose vials.

High-Cost Pharmaceutical Administration: Reduces volumetric loss when administering specialized biological, oncological, or therapeutic agents.

Clinical Procedures: Supports controlled volumetric injection where strict dose accuracy is required.

General Inpatient Care: Fits standard parenteral medication setup procedures across hospital networks.

FAQ

Q: How does this plunger design reduce dead space volume?

A: The plunger tip features a molded extension that projects into the syringe nozzle, displacing the fluid volume that normally remains trapped inside standard Luer hubs.

Q: What is the exact dead space limit under standard test conditions?

A: When tested according to ISO 7886-1 procedures, the residual volume after full plunger stroke is measured at or below 0.005 ml

Q: Are these syringes safe for patients with natural rubber allergies?

A: Yes, the barrel, plunger, and sealing gasket use synthetic polymers and elastomers, containing no natural rubber latex.

Q: What documentation is available for import registration in local health authorities?

A: Product technical files, including ISO 13485 certificates, CE declarations, biocompatibility test results, and batch sterilization reports, are provided upon request.

Q: Which needle types are compatible with the connector?

A: The standard Luer Lock and Luer Slip options accept ISO-compliant hypodermic needles ranging from 18G to 30G.
