Blood Transfusion TRIZ Cases
- Integrated Blood Bag Flow Paths With Compact Meandering Layout
Folded meandering flow paths let integrated blood bags keep long tubing in a compact sheet layout while reducing manual fusion bonding.
- Blood Bag Tube Connection Redesign for Kinking Prevention
Upper tube connections on blood bags simplify mounting and prevent kinking during centrifugation.
- Ventless Biomedical Fluid Filtration System with Gas Precharge
A ventless biomedical fluid filtration system uses gas precharge to displace biological fluids from processing components.
- Blood Bag Clamp with Asymmetric Slits for Simultaneous Tube Closure
A single blood bag clamp uses asymmetric slits to press tube walls inward, closing multiple flow channels simultaneously.
- Blood Treatment Filter with Segmented Pre-Filter and Main Unit
A blood treatment filter uses a segmented pre-filter unit to capture leukocytes while allowing platelets to pass through the porous membrane.
- Rotating Blood Bag Receiver for Uniform X-Ray Irradiation
Rotating the blood bag receiver compensates for low-energy X-ray absorption, eliminating nuclear leakage risks from radioactive sources.
