Suction Devices TRIZ Cases
- Macrostrain Dressing Interface for Negative-Pressure Wound Healing
A flap-based dressing interface separates pressure and strain zones to improve fluid delivery and macrostrain during negative-pressure wound therapy.
- Independent Macrostrain Device With Flanges for Wound-Edge Force
Negative pressure moves flanges to generate macrostrain at wound edges, supporting tissue growth and wound healing.
- Unified Wound Dressing Assembly for Faster NPWT Preparation
A pre-assembled dressing integrates sealing, irrigation, and netting layers to reduce cutting, foreign matter, and setup time.
- Polymer-Film Dressing Manifold for Reduced Tissue Ingrowth
Small-pore reticulated foam and bonded polymer-film layers support exudate transport while limiting tissue ingrowth and extending dressing wear.
- External Fluid Collection Barrier with Localized Adhesion
Localized adhesive strength secures an external fluid barrier while limiting skin irritation and supporting comfortable urine collection.
- Contracting-Layer Dressing for Negative-Pressure Wound Closure
Perforated contracting layers collapse under negative pressure to close linear tissue openings while reducing dressing-system complexity and suture discomfort.
- Integrated Multi-Layer Wound Dressing for Cut-Free Application
Pre-assembled multilayer dressing integrates sealing, suction, and irrigation to reduce preparation time and foreign material retention.
- Drain Bag Valve Shield Angled Outlet
Bell-shaped shield and angled outlet intercept urine flow to eliminate spilling risks for healthcare workers.
- Urinary Collection Device With Permeable Membrane For Buried Penis
Segmented fluid receiving portion and longitudinal portion accommodate buried penises while preventing leakage through directional membrane control.
- High-density evaporative bridge dressing for negative-pressure wound therapy
Capillary action in high-density wicking layers moves fluid to a breathable membrane, minimizing pressure drops and extending pump life.
- Reusable Cap for Negative Pressure Wound Therapy
A reusable cap couples a negative pressure source to common receptacles, collecting wound fluid through an injection conduit.
- Negative-Pressure Dressing Capillary Channels
A negative-pressure therapy dressing uses capillary action channels to direct fluid transport across the wound interface.
- Frangible Wound Packing Material for Negative Pressure Therapy
Pre-cut foam segments allow quick customization without tools, reducing closure time and contamination risks during wound dressing.
- Blood Collecting Device with Flexible Membrane for Air Separation
An integrated rigid and flexible collecting device separates air bubbles from blood, reducing inflammation risks in extracorporeal circuits.
- Extendable Dressing Manifold for Tissue Conformability
Segmented layers resolve tensile strength versus conformability trade-offs in negative-pressure dressings.
