A frontier proposal with a validation plan, not an implemented detector.
Intended capability
Evaluate the sensing evidence for “IV-bag and enteral-fluid level / empty-line detection (NeRF geometry)” in a consented, ground-truthed study. This is not a medical device, clinical monitor, diagnosis, or emergency alert.
This describes the intended outcome. Readiness is research concept, evidence is class C, and a catalog mapping or recording is not proof of this outcome at a real site.
Solution blueprint

This exact kit is one of 191 first-class designs. It includes geometry, objects, nodes, wording, scenarios, installation, limitations, and catalog-bound readiness.

Bundled recording
A related Healthcare scene
This is one recorded vertical scenario. It is not separate validation of every capability in the catalog.
01 The physics
Saline/nutrition fluid has eps_r~80 versus ~1 for the empty bag headspace, so the fluid volume is a strong, geometrically-localized dielectric scatterer; as the bag empties the reconstructed permittivity mass at the pole location shrinks and its scattering signature drops.
02 Shared processing path
CIR super-resolved delays localize the pole/bag geometry -> RFF/NeRF field reconstruction of eps_r over the bag volume -> compartment Kalman tracks fill fraction -> CUSUM detects the depletion trend / stalled level
This is a capability design path. Components may be shared with other catalog entries; it is not presented as a unique algorithm.
03 Validation plan
Own-hardware benchtop: known-volume saline bags stepped from full->empty at a fixed pole position, measuring eps_r-mass vs. gravimetric truth; use ESP32-wall geometry-imaging methodology as the reconstruction baseline.
04 Commercial hypothesis
'Line-and-bag level watch' — reduces empty-bag/occlusion nuisance alarms for infusion-safety and nursing-workflow leads.
