System requirement

What are included?

Hardware:

  • a ring sensor
  • a temperature sensor
  • a communication hub
  • accessories

Services:

  • 1-year subscription to cloud data storage and portal access
  • 1-year mobile data & warranty

What else do I need in the setup?

  • Computer/mobile phone/tablet with web browser and internet, which you will use as the monitoring station.
  • Check the reception of mobile phone signal at your site.  The system cannot operate in rooms with poor mobile reception.

Are there any requirement of the web browser?

The following web browsers and versions are recommended

  • Google Chrome (Version 68 or above)
  • Mozilla Firefox (Version 52 or above)
  • Apple Safari (Version 11 or above)
  • Microsoft Edge (Version 15 or above)

Does it rely on Wifi / What if I am away from the nurse station?

No Wifi is needed as the data is sent via mobile network. The monitoring portal can be accessed through the web browser on different mobile devices.

May I monitor from iPad?

Yes, it can be monitored through the web browser on any mobile device.

Is there any limit on the mobile data?

Unlimited mobile data for transmitting vital sign data from the communication hub provided by Belun is included.

May I see the data from multiple devices? Any limit on the number of monitoring staff?

No limitation on the number of monitoring staff. Staff can share the same login. Concurrent login is allowed.

May I monitor patients on different floors / centers?

Yes, you can monitor patients in any locations where there is internet access using the same portal and same login account.

Device specifications

How long does the battery last?

A fully-charged battery can last for up to 24 hours without a power supply connected. However, we suggest connecting the hub with a power supply using the charging cable and power charger provided for uninterrupted monitoring.

How long does it take to recharge the battery?

From 0% to fully charged, it takes ~3 hours. You can also connect the hub with a power supply continuously, so that you do not need to recharge the battery during monitoring.

What vital signs does it monitor?

Pulse oximetry (SpO2), pulse rate and body temperature.

Where to apply the sensors?

  • To accurately measure the body temperature, attach the temperature sensor with surgical tape under armpit.

  • To measure SpO2 and pulse rate, wear the Ring sensor on the index finger of the non-dominating hand (or the hand with less movement).

Is blood pressure available?

No, there is no blood pressure in the system.

How to adjust the Ring size if I cannot find one fit?

Use a rubber band to make the Ring smaller.

Portal specifications

Is there any alarm available?

Alarming sound (Alert audio) will go off when one of the devices detect any vital signs falling below / exceeding the pre-set thresholds. Make sure you have the speaker turned on. You can mute the alert audio for the next one hour.  The parameter will turns into red and keep flashing.

Is there any time lag for the data? Is it real-time?

The data will be updated every 1 minute and there are 2~3 minutes lag subject to the network.

How to set the data threshold?

The thresholds for SpO2, pulse rate, and body temperature can be set in the “Settings” Tab. The same threshold applies to all users.

May I set different threshold for different users?

The same threshold applies to all users.

May I switch off the alarm (alert audio) for a particular user in a particular period of time?

The alert audio setting applies to all users.

How many users can I monitor at the same time?

There is no limitation in the number of patients can be monitored at the same time but this is also subject to the capacity of the mobile network.

Do users have to be in the same location?

Users being monitored can be in different rooms, floors or buildings, as long as the location is covered by mobile signal.

Is there any alarm when the sensor is detached by the patient?

There is no alarm when the sensor is detached. However, you can see from the “Monitor” tab that the data value become “- -” in grey when a sensor is detached.

Data Privacy

How do I enter the bed information of the user being monitored?

Bed information such as bed number can be entered as “Tag” in the “Device” tab.

How is personal data protected?

The vital sign data is transmitted and stored anonymously. And, it is not recommended to use any patient information as the device “Tag”.

How long will the data be kept?

The historical data is kept for 90 days. You may export the data and stored in your own health record system before it is removed.

May I retrieve the data to keep in my own system?

Go to “History” tab.  Choose the record and export.

Disinfection

How to clean the device?

Use 70% alcohol or 1:99 bleach to wipe the device surface including all the parts.

User

May I monitor a user who is active and moving around?

Motion will affect the measurement accuracy of SpO2 and pulse rate. You could monitor active users during sleep.

Reliability of the measurement data

How can I check if the measurement data is valid and reliable?

After the ring is worn on the index finger and the patient’s hand is steady, the measured SpO2 will appear in the monitoring portal within 2 minutes. A person without hypoxia should have a SpO2 reading ≥ 95%. If the readings are below 95%, please check the followings:

  • the ring is properly worn (Refer to the Quick Guide)
  • the ring size fits the user
  • the hand of the user is not cold. (If it is cold, please warm his/her hand and check again 5 mins later.)

How can I differentiate a false alarm from a real risk?

There are thresholds that can be set for SpO2, pulse rate and body temperature in the “Settings” tab. When the measurement result of either one parameters is below/above the thresholds, the data will turn red and there will be an alert. There are 2 scenarios that a false alarm may be triggered:

  1. Body movement: As the accuracy of the SpO2 and pulse rate measurements will be affected by the body movement, hence, we would suggest switching OFF the alert when continuous movement is expected, e.g., meals and medication.
  2. Sleep apnea: For subjects with sleep apnea, there will be a drop in SpO2 during an apnea event. As long as the reading goes back to >93% after 1-2 minutes of drop, it is normal for a subject with sleep apnea.

Example of body movement during breakfast which has triggered a false alarm:

After dinner:

Any subjects should be avoided from using the system?

Users whose SpO2 readings cannot be measured by a traditional finger-type pulse oximeter due to poor circulation.
