Less searching: Tedious search operations requiring a large number of personnel are avoided.

Fewer interruptions: Approximately 50% of people return on their own (detectable by direction of travel recognition)

Greater safety: patients with dementia or disorientation remain in protected areas

Disoriented persons wear dementia tags in special wristbands. When they enter exit areas, an alarm is triggered or the door is locked. The times of day when the alarm is triggered can be programmed individually.

• Direction detection (alarm resets upon return)
• Door contact (alarm only when door is open)
• Accompanying function (care tag suppresses alarm during accompanied exit)

Residents can trigger personalised emergency calls from all areas – stairwells, gardens, corridors.

The call trigger is worn on the wrist and combines indoor positioning with nurse call.

Calls can be made anywhere where receivers are installed – even outdoors.

1. Staff care day (near the caller)
2. Nurse UI app or web interface
3. Connected alarm server (ESPA X)

Use as protection for disoriented persons (alarm when leaving permitted zones)

Use as a room key for unlocking the occupant's room door

Night-time security: Automatic alarm in the event of unauthorised door openings outside operating hours

Protection of sensitive areas: Medication rooms, cleaning rooms and technical areas remain secure.

Flexible alerting: combination of disorientation protection (during the day) and general door alarm (at night)

Manual control: Time-out rooms and isolation rooms can be activated individually as required.

Time-based alarms: Doors can be configured to trigger alarms only at certain times – e.g. main entrance between 10 p.m. and 6 a.m.

Intelligent combination with disorientation protection: During the day: Alarm only for patients with dementia day

At night: General alarm whenever a door is opened – regardless of who opens the door

Profile-based and manual control: Time profiles for regular areas (automatic arming/disarming) – Manual activation for time-out rooms, isolation rooms or temporarily restricted areas.

Individual configuration depending on the ward and patient situation

Easy installation: The door contact is mounted using double-sided adhesive tape and is battery-operated.

Psychiatric wards: protection of medication storage areas and therapy rooms

Care homes: Securing main and side entrances at night

Dementia wards: Combination of protection for disoriented patients during the day + general protection at night

Protection against unauthorised removal and child abduction

Automatic alert when leaving defined areas

Electronic mother-child matching for secure identification

Seamless protection without video surveillance

Baby tags for newborns:

Every newborn baby is given a tamper-proof ankle band which triggers an alarm if removed.

Zone-based protection:

Care2Graph defines protected areas (delivery room, maternity ward, neonatal unit). Leaving these zones triggers an immediate alarm. Optionally, an additional door lock or camera control can also be activated.

Electronic mother-child assignment

A pairing between parent tag and baby tag for extra safety when caring for and transporting infants.

Perimeter protection (alarm when leaving the station)

Tamper alarm (in case of tampering or removal of the band)

Automatic door locking at defined exits Mother-child matching (electronic assignment)

1. Mobile tags receive a position from position markers.
2. These forward the position together with their own ID and, if necessary, an alarm via 868 MHz to the receiver.
3. The receivers send the messages to the Care2Graph server via the local network.
4. The Care2Graph server interprets the data and generates alerts, which are transmitted to the respective users via the selected interfaces.

communication scheme C2G

The alarms can be transmitted to staff in a variety of ways:

1. NurseUI app provides alerts on a smartphone (Android or iOS)
2. NurseUI interface provides alerts via all browser-enabled devices in the network, e.g. PCs, smart TVs, tablets
3. Alarms can be forwarded to existing call systems or alarm servers via several ESPA interfaces.
4. REST interface integrations offer the option of displaying alarms in the software you use.

Alarms are normally reset via the respective system used, with the exception of older call systems with ESPA 4.4.4 interface.

Alarms based on positions:

• Protection for disoriented persons
• Protection of maternity wards
• Asset-Tracking

Alarms triggered by call triggers and sensors:

• Mobile nurse call system
• Radio call with permanently installed call and pull buttons
• Personal emergency call with fall detection
• Tamper-proof contacts for baby monitoring and asset tracking
• Door alarm

Alarms due to technical faults:

• Hardware monitoring: All installed devices send a so-called heartbeat every 30 seconds, which confirms their functionality to the system.
• Battery alerts: All mobile tags and trackers send a battery status update every 30 seconds.

Care2Graph combines active RFID, BLE and NFC in a mobile tracker.

When a mobile tag communicates with an RFID or Bluetooth Low Energy device, the tag receives the ID of the device in its vicinity. This allows the mobile tag to locate itself. The tag regularly sends the information about the positions it has received to a receiver in the network via a sub-gigahertz frequency.

Possible position markers:

Position markers RFID / Position markers lift (RFID) / Position markers BLE / BLE door fittings

It would seem obvious to use existing Wi-Fi or Bluetooth communication. However, these two technologies have the disadvantage that the signals usually cannot penetrate the human body, or can only do so to a very limited extent. This poses a safety risk, particularly for mobile call systems and personal emergency calls.

For this reason, Care2Graph uses its own radio coverage for communication and BLE communication only as a back-up solution. This has many advantages:

• The radio network is designed purely for alerting purposes.
• New investment in new WLAN or BLE access points can be avoided
• There will be no additional licence costs for location tracking from the access point manufacturers.​
