- Urinal Condom Application With Detachable Vacuum Sealing
A sealed vacuum interface with uneven surfaces supports reliable suction while allowing the pump and connection unit to detach easily.
- Laser Vein Imaging Via Sequential Averaging and Visible Projection
A scanned laser maps blood-rich structures, while sequential image averaging improves vein contrast and resolution for vascular access.
- Series-Filter Tissue Collector for Size-Specific Graft Selection
Different pore sizes separate tissue fragments during collection, helping select appropriate particle sizes for tissue grafts.
