Wound Drains TRIZ Cases
- Hyperbaric Dressing Oxygen Delivery and Exudate Removal
A hyperbaric dressing delivers oxygen to wounds while removing exudate through a layered permeable structure.
- Radiopaque Catheter Shaft with Multifilament Reinforcement
A catheter shaft uses a radiopaque multifilament reinforcement layer between tubings to provide flexibility and toughness.
- Single Venous Access Hypothermia Device for Rapid Cooling
A blood recirculating apparatus uses a single venous access to cool the heart and brain during cardiac arrest.
- Coated Urinary Catheter Preventing Tissue Occlusion
A lubricant and antimicrobial coating on a urinary catheter allows tissue to conform under negative pressure, preventing drainage hole occlusion.
- Coaxial Wound Drain and Antibiotic Delivery Device
A coaxial medical device combines a drainage lumen with an adjacent substance delivery channel for controlled antibiotic release.
- Dual-Port Surgical Drain for Lymphatic Fluid Analysis and Therapy
A dual-port surgical drain collects lymphatic fluid for biomarker analysis while delivering targeted therapeutics through a single incision site.
- Implantable Shunt with Integrated Pressure and Flow Sensors
Integrated sensors enable non-invasive real-time monitoring of intracranial pressure and flow rate, reducing revision surgeries caused by drainage errors.
- Grommet Lip Seal for Wound Conduit Leakage
Segmented grommet lip seals maintain conduit position adjustability while preventing fluid leakage from wound dressings.
- Medical Drain Device Sensor System Flow Regulation
An automated medical drain device uses pressure sensors and a flow regulator to track drainage volume and alert caregivers of accumulation issues.
- Multi-port therapy unit for simultaneous wound treatment
A multi-port therapy unit connects multiple dressings to a shared vacuum source and fluid reservoir.
- Catheter Locking Mechanism for Secure Distal End Configuration
A catheter lock system secures the distal end configuration using a sliding button and locking article within a hub structure.
- Carrageenan Barrier Film for Hydrophilic Catheter Packaging
A bio-based paper substrate coated with a hydrophobic carrageenan film protects medical devices from water damage while maintaining sterility.
- Flushable Catheter Using Biodegradable Polymer Blend
A urinary catheter made from a sugar and starch blend dissolves completely in turbulent water within six hours.
- Segmented Foam Wound Dressing for Exudate Management
A wound dressing system uses a segmented polyurethane foam core to maintain intimate contact with the wound site while managing fluid levels.
- Inline Wound Leakage Collection Device with Perforated Tubing
Perforated tubing channels wound leakage into an inline absorbent chamber, reducing canister bulk and infection risk during negative pressure therapy.
- Manual Negative Pressure Pump with Spring-Regulated Valve
Spring-biased valve maintains therapeutic pressure against ambient leaks, enabling self-administered treatment without electronic controls.
