ABSTRACT:
The present invention discloses an electronic sphygmomanometer calibrating tool, which comprises a platform being coupled to a control system; at least one tool being disposed on the platform for accommodating a testing electronic sphygmomanometer, and the tools being individually coupled to the platform and a pressurizing device through an electric circuit and a gas pipeline; a pulse signal blood pressure simulator being coupled to the gas pipeline, such that when the electronic sphygmomanometer is calibrated, the pressurizing device pressurizes the testing electronic sphygmomanometer by pressurizing the gas pipeline and the control system set the initial state and the maximum pressure for the testing electronic sphygmomanometer. Since the values of the blood pressure from the initial state to the maximum value in increased linearly, therefore the control system can calculate the rest of the values to calibrate the testing electronic sphygmomanometer. Then, the pulse signal blood pressure simulator is turned on to set the pulse blood pressure for the testing electronic sphygmomanometer. Therefore, more than one electronic sphygmomanometer can be set up and calibrated at the same time by the interconnecting structure between the control system and the tools in order to save time and improve the precision of the calibration.
