Wound Drains TRIZ Cases
- Wearable Vacuum Pump Housing for One-Hand Vessel Release
A separable snap-lock housing lets wound vacuum therapy users release and discard the fluid vessel with one hand while keeping secure wear.
- Implantable Shunt Antenna Assembly for Wireless Geometry Adjustment
A dual-frequency communication element lets an implanted shunt adjust lumen geometry wirelessly while also handling power transfer and data exchange.
- Implantable Antenna Assembly for Adjustable Shunt Communication
A dual-frequency implantable antenna assembly enables non-invasive shunt adjustment, bidirectional communication, and power transfer with less bulk.
- Shunt Valve Assembly for Stable Ventricular Pressure Control
An adjustable shunt valve uses threshold opening pressure and feedback flow control to limit CSF overdrainage and stabilize ventricular pressure.
- Adjustable Shunt Valve Assembly for Stable Ventricular Pressure
A spring-biased shunt valve with adjustable opening pressure regulates CSF flow to prevent overdrainage and maintain stable ventricular pressure.
- Equine Intubation Adapter With Sliding Backflow Diverter
A sliding sleeve adapter closes during air puffs and opens a reflux drain under backflow, keeping equine stomach contents out of the operator's mouth.
- Implantable CSF Valve With Gravity Compensation Against Overdrainage
A movable valve body and spring use body position to vary CSF drainage pressure, limiting hydrostatic overdrainage in NPH shunts.
- Barbed Stopcock and Clip Assembly for Unrestricted Drain Flow
A 180-degree barbed stopcock and clip secure medical tubing without adapters or tape while maintaining large-bore drainage flow.
- CSF Shunt Valve Assembly With Adjustable Opening Pressure
A spring-loaded cassette valve sets selective opening pressure to regulate CSF drainage and prevent ventricular overdrainage.
