operating principle of the other physiology parameter such as blood pressure pulse rate body fat body weight etc is in the same manner and thus its details will not be described hereafter as described in the above finally the measurement data dt is stored in the memory unit 103 the memory unit 103 can be implemented by a flash memory or other current or future storage device fig2 shows a schematic diagram illustrating the health management device 200 according to another embodiment of the invention the difference between the health management device 100 and the health management device 200 is that the memory unit 203 is a swappable swap device since the health management software 203 a is built in the memory unit 203 when the memory unit 203 is unplugged from the health management device 200 a transmission interface 204 such as universal serial bus usb can transmit the measurement data dt to a computer system 205 or one other compatible platform 206 the transmission interface 204 includes at least one mass storage class such as external hard disc flash drive card reader etc the additional driver is not required to be installed in the computer system 205 or the compatible platform 206 the health.
