A low-cost, rugged, multi-functional wearable device, (wrist-band) that can help detect and address in a timely manner, some of the drivers of maternal and child ill-health.

What is it?

A low-cost, rugged, multi-functional wearable device, (wrist-band) that can help detect and address in a timely manner, some of the drivers of maternal and child ill-health namely:
• Preeclampsia
• Infection (through fever spikes)
• Non-adherence to Antenatal Care scheduled visits in a remote-rural setting

How is it used?

The MotherBand is a wristband with a digital display that is worn on the wrist, like a watch. The data collected in the band is transmitted to a central server that records all activities that the band is programmed with.

What technologies does it incorporate?

1. An infrared sensor to detect body temperature
2. A sensor with a single wave photoplethysmographic wave form and ECG waveform

To process the data generated from the sensors

To transmit data stored in the processor

GPS device and RF transmitter to transmit GPS information

Digital watch with alarms actviated by a central server for appointment reminders

How does it work?

The MotherBand is worn during the time of pregnancy. Upon diagnosis of pregnancy, one Motherband with a unique number s proved t every child bearing woman.

Preeclampsia – One of the two sensors in the wearable device will record changes in arterial blood volume and heart rate using the photoplethysmography and ECG sensor – Changes from normal readings will trigger the GPS tracking device to become active, which in return will transmit signals to a central server. Information recorded on the central server will be
1. Readings from the preeclampsia sensor
2. Real-time location of the wearable device and thus , the patient
This information is relayed to health care providers on their laptops/phones which are connected to the central server
Based on the GPS location, the local health care provider can send medical aid based on the GPS location of the MotherBand

Temperature spikes are detected by the temperature sensor and transmitted to a central server. Temperature spikes on consecutive days will trigger an alarm to the health care provider who can then contact the patient, asking her to come to the care provision setting – hospital/clinic for diagnosis and treatment of temperature spike.

Adherence – Every time a MotherBand is given to a mother who is diagnosed with pregnancy, date of registration and unique number of the MotherBand is entered into a central server. An evidence-based ante-natal visit schedule is then activated based on the date of registration/conception of pregnancy – which will send automated alarms and short messages that can be seen on the MotherBand display as simple message alerting the mother on her visit to an antenatal clinic for a specific scheduled ante-natal check. reminders will be provided one day prior to and on the day of the scheduled ante-natal visit.

Time – The MotherBand also serves are a regular digital time-piece

Who uses it?

Primary stakeholder – Wearer of the device, who is a pregnant woman
Secondary stakeholder – Health care provider – A practicing obstetrician/physician or nurse-care practitioner who can access patient information on his her device (laptop/smartphone)

Information (data) from each MotherBand is linked to a specific patient.

Why does it help?

The MotherBand can aid in:
1. Educating patient on self-care during pregnancy – t watch out for risk factors once usefulness of the MotherBand is explained to pregnant women and their families upon registration of pregnancy
2. Improve access to emergency care – alerting health care providers of impending preeclampsia in symptomatic patients thus improving TIMELY care provision – reducing incidence of eclampsia and associated pregnancy-related complications. Additionally, help detect potential infection in target population. – Can help reduce incidence of Maternal Mortality as a result of preeclampsia and antenatal infection
3. Improve population adherence to antenatal check-ups – Behavior modification
