Dual-Chamber Harm Reduction Syringe Clip-On Device

Abstract

This project proposes a low-cost dual-chamber syringe clip-on attachment intended to reduce internal blood contamination during intravenous drug use.

The proposed intervention is designed for compatibility with existing syringe infrastructure used within needle exchange and harm reduction services.

The Problem

• Blood contamination within syringe systems
• Injecting-related infection and abscess formation
• Vascular damage and clotting complications
• Avoidable emergency hospital admissions
• Limited existing interventions addressing contamination dynamics

The Solution

A clip-on dual-chamber syringe attachment creating a mechanical separation buffer between injected substance and blood backflow.

• Low-cost retrofit design
• Compatible with standard syringe systems
• Disposable or recyclable format
• Designed for NSP distribution
• Minimal behavioural change required

Expected Impact

• Reduced injecting-related infections
• Reduced vascular complications
• Improved harm reduction safety outcomes
• Lower NHS urgent care burden
• Potential public health cost savings
