Project Details

What is a SyringeGrip?

The SyringeGrip was developed to address usability challenges in controlled dispensing scenarios, especially where precision and repeatability are critical. The core goal was to create a stable yet adaptive interface for standard BD syringes.

Problem

  • Inconsistent Fit Across Users
    Users with different finger sizes struggled with the one-size-fits-all grip, leading to discomfort and reduced control.

  • Manufacturing Variance in Syringes
    BD syringes manufactured in different regions showed slight variations in outer diameter. The original design compensated with a looser fit, sacrificing stability.

Key Improvements

  • Clinically Informed Design
    Collaborated with a medical professional to gather user feedback and tune ergonomic refinements.

  • Spec-Driven Fit Optimization
    Studied manufacturer specifications (BD, Terumo, Glatopa) to design around real-world tolerances.

  • Adaptive Geometry
    Introduced crush ribs and improved contouring to maintain a self-aligning fit without compromising universal compatibility.
