Infusion Needles TRIZ Cases
- Medicament Cap Shield Remover With Slit Protrusions
Segmented protrusions in a slit body reduce assembly force while tapered sections enhance grip only when partially removed.
- Needle Shield Internal Roughness for Alignment and Sterility
Internal surface roughness reduces adhesion between the shield and hub, resolving alignment errors and contamination risks during automatic assembly.
- Needle Shroud Creep Prevention via Radial Support Component
Integrating a structural support element within the shroud cavity prevents beam creep under cap pressure, preserving lock mechanism reliability.
- Subcutaneous Injection Device with Tissue Gripping Mechanism
A hand-operated device guides a syringe and grips tissue for subcutaneous injections.
- Pen Needle Assembly Apparatus for Safe One-Handed Disposal
A pen needle assembly apparatus uses a movable gripping mechanism to secure and manipulate the device.
- Angled Retractable Needle Prevents Upward Pivotal Force
An angled safety enclosure prevents upward pivotal force on the needle, ensuring stable blood flow and reducing tissue damage risk.
- Puncture Needle Blade Tip Angle Reduction via Segmented Surface
Segmented blade surface portions reduce the tip angle and puncture resistance, enabling smoother vessel wall piercing without excessive force.
