Device for computing height and angle of sickbed

The utility model relates to a height and angle calculating device for a sickbed, including a motor drive unit, a pulse- wave generating unit, a signal conversion unit, a data processing unit and a display unit, wherein, the motor drive unit outputs a first signal to the pulse- wave generating unit for interpretation; the pulse- wave generating unit outputs a first pulse wave to the signal conversion unit and then output a second pulse wave to the data processing unit; the data processing unit stores a plurality of data of the entire heights of the sickbeds and a plurality of data of the angles of the sickbeds; after interpreting the second pulse wave, the data processing unit further outputs a second signal to the display unit, which interprets the second signal and then further display the material of the height and the angle of the current sickbeds. In this way, the displayed sickbed material can be provided for the medical workers for medical research.
