Bempu TempWatch

The Bempu Hypothermia Alert Device is a bracelet composed of a silicone band, thermistor metal cup, and plastic casing. The device contains a printed circuit board that holds an algorithm that logs temperatures and alarms when the newborn reaches an unhealthy temperature. The device uses orange, blue, and light LED indications to communicate the device state. When the baby is warm, a blue light blinks every 30 seconds to indicate that the baby’s temperature is normal. When the baby’s temperature is low, an orange light blinks once every five seconds and an alarm sounds for one minute and repeats every 5-15 minutes to indicate that the baby needs warmth. When the band is not being worn it will switch into an off mode that is indicated by a white light blinking every 30 seconds.

The Bempu bracelet is water-resistant and should be regularly cleaned while in use. All wipes that are suitable for baby use can be used for cleaning.

The device does not require preventative maintenance. Bempu Health has a customer care line that directly connects the customer to product engineers. If the engineers cannot assess the problem over the phone, courier pick-up will be arranged so that the engineer team can discover the root of the problem. A new device would then be sent out to the customer.^{Interview with representative in 2019} The product has a warranty of 1 year and any product that does not meet selling standards will be replaced.^{Interview with representative in 2019} Additional training is not required for parents or nurses to operate the device.

The product can be worn on a newborn’s wrist for up to 30 days. Once the product has reached its end-of-life, the LED indicator will show the white light for one full day and then go dark. The device has a shelf life of 3 years.^{Interview with representative}

A 2018 paper in the Journal of Maternal-Fetal and Neonatal Medicine stated, “A total of 461 neonates were screened for hypothermia, giving 2428 temperature readings. Three hundred and eleven of 461 babies experienced hypothermia at some point. The 461 babies studied experienced 495 episodes of hypothermia in total. The sensitivity and the specificity of the bracelet in diagnosing hypothermia were 98.6% and 95% respectively. The positive and negative predictive values of the bracelet were 83.6% and 99.6%, respectively. The accuracy of the bracelet in diagnosing hypothermia was 95.8%.”

The bracelet should not be attached too tightly to the infant’s wrist. The device should not be sterilized or submerged under water. The device is radiation free.
