Tourniquets TRIZ Cases
- Non-Circumferential Wrist Compression for Radial Artery Patency
Targeted ulnar or radial wrist compression improves transradial access, preserves radial artery blood flow, and speeds hemostasis.
- Radial Artery Closure Using Upward Tissue Traction for Hemostasis
Upward tissue traction with suction closes radial punctures while preserving arterial patency and reducing pain from direct wrist compression.
- Pressure-Sensitive Strap Layout for Accurate Muscle Oxygen Monitoring
Pressure sensors and linear optical detectors help control strap loading, improving muscle oxygen and hemoglobin monitoring during exercise.
- Extremity Tourniquet Buckle and Ratchet for Slack-Free Tightening
A tension-setting buckle establishes baseline strap force, then a ratchet or windlass removes slack for reliable blood flow occlusion.
- Oral-Nasal Compression Structure for Adjustable Epistaxis Control
Adjustable magnetic or spring compression pinches facial tissue to restrict blood flow, reducing nosebleed irritation and slippage.
- Integrated Tourniquet Garment for Cone-Shaped Limb Stability
An elastic garment secures tourniquets on obese or cone-shaped limbs, reducing skin injury, displacement, and OR staff handling.
- Inflatable Compression Sleeve for Stable Eccentric Vein Pressure
An adhesive inflatable sleeve standardizes eccentric vein compression, prevents shifting, and allows precise pressure adjustment.
- Convertible Tourniquet Belt With Integrated Tensioning Band
A wearable belt hides a pre-positioned tensioning band and rod, enabling fast limb compression when a separate trauma tourniquet is unavailable.
