Blood Flow Measurement TRIZ Cases
- GI Tissue Perfusion Clamp With Multi-Sensor Pressure Measurement
Controlled pressure and combined optical, impedance, and magnetic sensing enable faster, more objective GI tissue perfusion checks during anastomosis.
- Integrated Probe Coupler Assembly for Microvascular Flow Monitoring
A probe coupler assembly integrates a monitoring device within a vessel coupling structure to enable direct fluid flow detection.
- Heat Flux Sensor for Non-Invasive Blood Perfusion Measurement
Direct heat flux measurement resolves accuracy loss from indirect thermal inference, enabling precise non-invasive blood perfusion assessment.
- Graphene Microelectrode Flow Meter for Biofluid Sensing
Monolayer graphene microsheets measure biofluid flow velocity through triboelectric currents, resolving sensitivity and biofouling trade-offs.
- Thermodilution Catheter Dual Lumen Blood Flow Measurement
Dual lumen catheter delivers indicator fluid and measures temperature changes for blood flow rate calculation.
- Cardiac Performance Determination Using Plethysmograph and ECG Signals
A cardiac performance system calculates stroke volume using plethysmographic and electrocardiogram signals.
- Intrathoracic Volume Normalization Using Predicted Body Weight
Patient monitoring apparatus normalizes intrathoracic volume parameters using predicted body weight derived from height and gender.
