Finnish company Spektikor has developed the disposable heart rate indicator, which comprises a heart rate sensor with two electrodes and a LED indicator, which are connected by a 35-cm-long wire, Xinhua reported.
The sensor is placed on a patient's chest and the LED indicator is stuck to the patient's cheek. If the heart rate is within the normal range, the LED indicator will flash green with each beat. If the heart rate is dangerously low or high, the light will turn red.
Company officials said the product will help hospital staff speed up work as it was not necessary to check the pulse manually. In addition to saving time, it will also enhance safety, as the LED indicator can be seen clearly at a glance.
