1. A disposable heart rate indicator for indicating a heart rate of an immobile person, comprising:
a power source for generating power to the heart rate indicator; at least two electrodes for detecting a person's heart beat, the electrodes being attachable to the person's skin for duration of use; a processor and a light signal emitting head, the processor being operatively coupled to the at least two electrodes and being configured to receive a signal on each heart beat detected by the electrodes and visually indicate a detected heart rate via optical light emitted by the light signal emitting head; a base which is at least partly made from a flexible material and wherein the power source, the at least two electrodes and the processor are fixedly installed; and a conductor coupled between the light signal emitting head and the processor, the conductor being configured to extend from a heart beat detection area formed by the electrodes and the processor, the conductor being an electrical conductor or an optical conductor; wherein the heart rate indicator is configured to be placed on the person's chest underneath clothes, and the conductor is configured to extend from under the person's clothes so as to bring the light signal emitting head outside of the clothing, thus making it visible during use, wherein the conductor is extendible in a lengthwise direction and is extendible outside of a surface of the base, thereby allowing the light emitting signal head to be disposed a distance away from the base, and wherein the heart rate indicator further comprises a detachment part that is coupled to the conductor, wherein the conductor is configured to extend lengthwise from the base by pulling the detachment part away from the base so that the conductor and light signal emitting head extend from the base and are visible during use. |
