IMCO 4T Device
The IMCO 4T Device enables community health workers to perform accurate, multi-disease triage for TB, malaria, and neonatal sepsis — then monitor continuously through transport, so your clinical team knows what's coming before it arrives.
Designed from the ground up for community health workers in resource-limited settings — offline-first, solar-chargeable, and operable after four hours of training.
Ruggedized Android tablet with WHO IMAI clinical logic delivering 5-level acuity scores, multilingual voice guidance in five languages, and pictogram-based interfaces for low-literacy users. Operates fully offline with periodic sync to national health information systems when connectivity is available.
Wearable sensor kit designed for rapid single-action placement. Continuously acquires six vital sign parameters and streams data from CHW contact through patient transport to facility arrival — enabling receiving clinical teams to monitor before the patient reaches the door. Solar-assisted charging, no consumables required.
Multi-layer AI clinical decision support generating acuity scores and disease pathway flags for TB, malaria, and neonatal SIRS. Human-in-the-loop mandatory — all outputs require clinician confirmation before action. WHO IMCI intervention prompts drive structured care decisions at every acuity level.
Every encounter becomes a timestamped, geotagged digital record exportable to national health information platforms. Designed for seamless integration with existing CHW program infrastructure and national syndromic surveillance systems.
Not an equity add-on — a patient safety requirement for Nigerian clinical settings.
Higher rate of occult hypoxemia misread in patients presenting with Fitzpatrick V–VI skin tones when standard single-wavelength pulse oximetry is used — producing false-normal readings that mask life-threatening hypoxemia.
Standard pulse oximeters systematically overestimate oxygen saturation in darker-skinned patients. The 4T Device applies multi-wavelength reflectance photoplethysmography paired with a Fitzpatrick-stratified correction algorithm to address this directly.
In Nigeria, where patients predominantly present with Fitzpatrick V–VI skin tones, deploying uncorrected oximetry is not a gap in equity — it is a clinical error. The 4T Device was engineered to eliminate it.
This skin-tone correction capability is embedded at the hardware level across every unit deployed — not an optional feature, not an add-on configuration.
The 4T Device closes the data gap at every step of the patient journey.
Voice-guided symptom screening in five languages. Sensor band attached rapidly with single-action placement. No training beyond four hours required.
ESI acuity score and disease pathway flags for TB, malaria, and neonatal SIRS generated immediately. Clinician confirmation required before action.
Vitals stream continuously after sensor placement. Yellow and Red alerts notify the receiving facility before the patient arrives.
Clinical team has the complete vital sign trend for the entire transport period. FHIR R4 record auto-exported to electronic medical record.
Encounter data syncs to OpenMRS and DHIS2 for national syndromic surveillance integration when connectivity is restored.
A functional simulation of the 4T Device CHW workflow — from patient intake through vital sign capture, AI assessment, telemetry monitoring, and FHIR record export.

Simulation demonstrates complete CHW workflow. Development prototype — Nigerian primary care CHW workflow.
All AI outputs require physician confirmation before clinical action.
We are seeking a Nigerian primary care or trauma facility as our clinical validation partner — to generate the evidence base for national-scale deployment across Nigeria and West Africa.
Active patient volume across trauma, TB, malaria, or maternal and neonatal presentations. Existing CHW or nursing workforce. Interest in digital health integration and Nigerian IRB capability.
Full device deployment at no cost to the facility. Dedicated technical support and CHW training. Sub-grant funding to support site operations, IRB coordination, and physician oversight time.
Validated triage accuracy data published open-source. Full FHIR integration with your existing EMR. The clinical evidence base for national-scale deployment across Nigeria and West Africa.
We are not asking for a commitment. We are asking for 30 minutes to demonstrate the device, hear about your clinical context, and explore whether this technology could serve your team.

| Term Type | Official Name | Description & Context |
|---|---|---|
| Brand Name | IMCO 4T Device | Primary commercial and clinical identifier. Used in all external communications, regulatory submissions (FDA De Novo, NAFDAC Nigeria), labeling, and partner documentation. |
| 4T Acronym | Trauma · Telemetry · Triage · Treatment | Each letter maps to a clinical function: Trauma (point-of-contact assessment), Telemetry (continuous vital sign acquisition), Triage (AI-assisted acuity scoring), Treatment (WHO IMCI intervention-driven action prompts). |
| Platform Title | Modular Clinical Screening Platform | Descriptive proposal and regulatory title positioning the system as scalable health infrastructure rather than a single-point device solution. |
| Module 1 | Pre-Triage Module | Offline-first, ruggedized Android tablet with voice-guided WHO IMAI interface. Input and cognitive layer of the platform. Five languages. Operates independently of connectivity. |
| Module 2 | Telemetry Triage Module | Wearable sensor kit for rapid single-action placement. Six-parameter continuous acquisition: SpO₂ (with Health Equity by Design skin-tone correction), Heart Rate, Blood Pressure, Temperature, Respiratory Rate, single-lead ECG. Sensing layer of the platform. |
| Design Principle | Health Equity by Design | Multi-wavelength reflectance PPG SpO₂ correction system with Fitzpatrick-stratified algorithm addressing the 3–4× higher occult hypoxemia misread rate in Fitzpatrick V–VI patients. Documented by Sjoding et al., NEJM 2020. In Nigeria, a patient safety requirement — not an equity add-on. |
| Clinical Feature | Pre-Hospital Transport Monitoring | The Telemetry Triage Module operates autonomously after CHW attachment — streaming vital sign data continuously through patient transport to facility arrival. Receiving clinical teams see vital sign trends and alert status before the patient reaches the door. |
| AI Architecture | Multi-Layer AI Decision Support | Layered AI clinical decision support incorporating rule-based clinical logic, machine-learning triage models, and disease-specific classifiers for TB, malaria, and neonatal SIRS. Human-in-the-loop mandatory — all outputs require clinician confirmation. |
