Abstract: A micro pump having noise-reduced pressure-releasing structure includes a convergence plate, a valve sheet, a chamber plate, and a micro pump. The convergence plate has a convergence outlet and a discharge outlet. The valve sheet has a valve hole and a discharge recessed portion. The chamber plate has a recessed hole, a fluid determine hole, fluid through holes, and a receiving trough. The micro pump is in the receiving trough. During operation of the micro pump, the fluid is firstly transmitted to the fluid through hole and the fluid determine hole to push the valve sheet, and the fluid determine hole pushes the discharge recessed portion to block the discharge outlet. Then, since the pressure of the fluid at the fluid through hole pushes the valve sheet, the fluid flows through the valve hole so as to be discharged out from the convergence outlet.

Abstract: A blood pressure device includes a first blood pressure measuring device, a second blood pressure measuring device, and a controller. The first blood pressure measuring device is to be worn on a first position of a wrist so as to obtain a first blood pressure information of the first position. The second blood pressure measuring device is to be worn on a second position of the wrist so as to obtain a second blood pressure information of the second position. The controller is electrically coupled to the first blood pressure measuring device and the second blood pressure measuring device so as to adjust tightness between the expanders and the user's skin, respectively. The controller receives, processes, and calculates a pulse transit time between the first blood pressure information and the second blood pressure information, and the controller obtains at least one blood pressure value based on the pulse transit time.

Abstract: An actuating and sensing module includes a first substrate, a second substrate, an actuating device and a sensor. A gas flow channel is formed by stacking the first substrate and the second substrate. The gas inlet, the gas flow channel and the gas outlet are in communication with each other to define a gas flow loop. The actuating device is disposed in the gas inlet of the second substrate and electrically connected to a control circuit to obtain a driving power. The sensor is disposed in the gas flow loop and electrically connected to a control circuit of the first substrate to transmit sensed data. While the actuating device drives outside gas from the outside, the gas is transported into the gas flow loop and sensed by the sensor.

Abstract: A blood pressure measurement module includes a top cover, a micro pump, a driving circuit board, and a pressure sensor. The top cover has a gas inlet hole, an accommodation trough, and an outlet channel. An inner wall of the accommodation trough is recessed to form a gas collection chamber in communication with the gas inlet hole, and the outlet channel is connected to a gas bag. The pressure sensor is electrically connected to the driving circuit board. The driving circuit board covers the accommodation trough of the top cover. The operation of the micro pump is controlled by the driving circuit board. The gas is continuously guided to the outlet channel and is converged at the gas bag by the micro pump. When the pressure of the gas in the gas bag measured by the pressure sensor reaches a valve value, the micro pump stops its operation.
