Hazardous Material Escort Robot
Client Background
A geriatric rehabilitation hospital that mainly admits elderly, disabled, and semi-disabled patients, with elderly patients accounting for the vast majority and prominent long-term care needs. Against the backdrop of accelerating population aging and national policies promoting elderly-friendly medical institution construction and the combination of medical care and elderly care, the hospital urgently needs to upgrade its smart ward system — solving problems such as elderly patient fall prevention, night monitoring, and care response, and providing a safer and more secure inpatient environment for elderly patients.
Core Challenges
High Nighttime Fall Risk
Intermittent Vital Sign Monitoring
Delayed Care Response
Family Communication Anxiety
High Nighttime Fall Risk
Specific Pain Points
Elderly patients face high fall risk when getting out of bed and using the restroom at night; manual rounds have long intervals and cannot achieve full coverage. Traditional camera surveillance raises privacy concerns, meets patient resistance, and is difficult to implement.
RACETEC Solution
Smart Mattress + Millimeter-Wave Radar · Frictionless MonitoringThe HarmonyOS Distributed Soft Bus connects smart mattresses and millimeter-wave radar to frictionlessly monitor behaviors such as bed exit, getting up, and falls. Risk events trigger second-level automatic alarms and notify the nearest caregiver — with no image capture throughout, ensuring privacy.
Intermittent Vital Sign Monitoring
Specific Pain Points
Elderly patients have multiple chronic conditions and frequent vital sign fluctuations; traditional wearables are uncomfortable and require frequent charging, so seniors are unwilling to wear them long-term, resulting in data gaps in monitoring.
RACETEC Solution
Smart Mattress · Frictionless Continuous CollectionSmart mattresses continuously collect vital signs such as heart rate and respiration — seniors need no wearable devices, and monitoring is completed naturally while sleeping. Abnormal fluctuations are automatically flagged and pushed to doctors, with monitoring data no longer interrupted.
Delayed Care Response
Specific Pain Points
Nursing resources are strained and night-shift staffing is insufficient, with long waits after patient calls; needs such as medication, repositioning, and toileting are difficult to prioritize reasonably.
RACETEC Solution
Task Dispatch Agent · Intelligent Dispatching
Through the Task Dispatch Agent, tasks such as calls, medication, and repositioning are automatically dispatched to the nearest caregiver's handheld terminal by urgency level based on caregivers' real-time location and busy status — high-risk events are prioritized, and care resources are evenly balanced.
Family Communication Anxiety
Specific Pain Points
Family members cannot learn the elderly patient's inpatient status in real time and worry about accidents such as falls and wandering; information asymmetry causes anxiety and distrust, with high doctor-patient communication costs.
RACETEC Solution
Safety Status Summary · Automatic Anomaly Push
With authorization, family members can view the elderly patient's safety status summary (sleep, activity, vital sign trends) via mobile devices. Anomalous events such as falls are automatically pushed and notified — keeping families at ease and naturally building doctor-patient trust.
Value Delivered
Fall Prevention, from "Nighttime Blind Spots" to "Frictionless Protection"
In the past, nighttime bed exits and falls relied entirely on caregivers' scheduled rounds — accidents occurring between rounds went unnoticed. Now smart mattresses and radar provide frictionless monitoring, with second-level alarms for bed exit and falls — transforming from "discovered after the fact" to "known the moment it happens."
Vital Sign Monitoring, from "Intermittent" to "Continuously Online"
In the past, seniors were unwilling to wear wristbands; data gaps occurred when devices were charging or forgotten, and vital sign fluctuations were often missed. Now smart mattresses frictionlessly collect and continuously record, with abnormal fluctuations automatically pushed — transforming from "won't wear, frequent gaps" to "monitored while lying down."
Care Response, from "Waiting in Line" to "Second-Level Dispatching"
In the past, after pressing the call bell, seniors waited for caregivers to finish their current work, with urgency levels indistinguishable. Now tasks are intelligently dispatched to the nearest caregiver by urgency, with high-risk events prioritized — transforming from "first come, first served" to "urgent matters first."
Family Communication, from "Anxious Guessing" to "Reassured Awareness"
In the past, family members only learned about the situation during visits, otherwise relying on guessing and asking. Now, with authorization, they can check the elderly patient's safety status at any time, with anomalous events automatically notified — transforming from "no peace of mind" to "reassured at all times."
