Abstract: A leg electric shock switch of an electronic walking aid comprises an upper insulating plate having a restoring resilience; an upper electrode plate, installed below the upper insulating plate; a lower insulating plate; a lower electrode plate, installed above the lower insulating plate; an isolating element, being a plate made of an insulating material, and coupled between the upper electrode plate and the lower electrode plate, and including a plurality of through holes; such that if the upper insulating plate is touched and pressed, the upper electrode plate will produce a deformation, and the upper electrode plate will be passed through the through hole and electrically contacted and connected to the lower electrode plate. Therefore, the manufacturing procedure is simplified and the cost is lowered to achieve the effects of improving the cost-effectiveness of the manufacture, promoting the application of low-cost consuming materials, and enhancing the product competiveness.

Abstract: The present invention discloses a method for automatically calibrating an electronic sphygmomanometer, which pumps air at a predetermined air pressure to a testing electronic sphygmomanometer to simultaneously pressurize a set of pressure sensors set for regular use and at least one other set of pressure sensors being interconnected in the electronic sphygmomanometer to detect whether or not the set of pressure sensors used at regular time is normal. The detected change of pressure during the detection is sent to a control module, and the control module will compare the detected value of each pressure sensor. If the comparison is matched, then it means that the set of pressure sensors used at regular time is normal; if the comparison is mismatched, then the pressure sensors are determined as abnormal and the air valve connected to such pressure sensors is shut, such that when a user uses the electronic sphygmomanometer for the next time, another set of pressure sensors will be started.

Abstract: The present invention discloses a tunnel type electronic sphygmomanometer measuring unit assembly that mainly improves the assembly between a measuring unit of a tunnel type electronic sphygmomanometer and a tunnel type electronic sphygmomanometer body of a prior art by installing an axle unit between the measuring unit of tunnel type electronic sphygmomanometer and the tunnel type electronic sphygmomanometer body to provide a multidirectional rotary function, such that the sphygmomanometer can be rotated in different directions by means of the axle unit to fit the posture of a user when a blood pressure is measured, and thus the invention enhances the accuracy of the sphygmomanometer for measuring blood pressure.
