Vaccination/Ovulation Diagnostics TRIZ Cases

A blood vessel position display device projects conforming vessel lines onto skin to guide needle puncture.

Oblique needle positioning prevents overlap with the target region, reducing radiation dose and examination time during stereographic imaging.

Electrochemical sensors on an ingestible capsule measure gastrointestinal parameters for targeted sampling.

Segmented handle design reduces manufacturing complexity while maintaining precise positioning accuracy for intracorporeal procedures.

Segmented diffusion channels enable continuous marker detection via ultrasound enhancement, resolving the trade-off between reliability and device complexity.

A sensor assembly uses a measurement chamber widening to stabilize flow-fronts across multiple sensors.

A remote medical diagnostic system processes multi-sourced patient data to determine vaginal disorder likelihood and recommend treatment options.

A multi-modal imaging paddle housing integrates a/LCI and OCT probes onto an endoscope exterior.

Nested biosensors enable precise anatomic localization while periodic transmission conserves energy during continuous monitoring.

Nested cannulas shield follicles from sharp punches during extraction, preventing mechanical trauma while maintaining precise harvesting.

Real-time diffuse reflectance feedback guides precise adipose deposition, preventing improper placement near muscles or ducts.

Fluorescence-based cytometer quantifies viral loads in exhaled breath to identify asymptomatic carriers.

An integrated distal sensor and illuminator in a handheld probe eliminate bulky external cabling, enabling precise internal tissue visualization.

A tissue harvesting cutter uses a slit and high-frequency electrodes to sever biological material while minimizing trauma in narrow anatomical spaces.
