Abstract
A conventional healthcare data acquisition device for advising on various healthcare data currently exists by measuring an impedance across a patient body. To measure the impedance of the patient in the conventional device, the patient grips a pair of current electrodes and measurement electrodes by both palms. The conventional device, however, is not accurate because the resistance value becomes very large due to the presence of the joints and the small diameter of the fingers. Moreover, the adjacent fingers may at different times be apart or in contact with each other, thus resulting in a varying current path. The invention overcomes these problems by providing a healthcare data acquisition device having a pair of current electrodes to contact specifically left and right thumbs of a user in order to apply a stable current, and a pair of measurement electrodes to contact a pair of specified portions which are respectively located between the left and right thumbs and wrists of the user so that stable impedance and voltage can be measured.
