Abstract: A foldable electronic device includes a central base, a hinge module, a plurality of wings, a plurality of driving element, a plurality of panel bodies, an elastic module and a flexible screen. The hinge module penetrates through the central base and capable of rotating synchronously and reversely. The driving elements are sleeved on and synchronously rotate with the hinge module. The panel bodies are pivotally connected to the wings and can linearly slide relative to the driving element. The flexible screen is disposed on panel bodies and the wings, and has a bendable area. When the panel bodies are in the unfolded status, the flexible screen is flattened, and the wings and the central base support the bendable area. When the panel bodies are in the folded status, the bendable area is bent, and the wings and the central base define an accommodating space for accommodating the bendable area.

Abstract: A blood pressure monitor comprising a main engine and a cuff is provided. The main engine has a housing, a pump which is disposed in the housing, and a plurality of first venting pipes. A plurality of first through-holes is formed on the housing to gas-communicate with the pump. The cuff has a gasbag and a plurality of gas nozzles. The gas nozzles extend from the gasbag to connect with the first venting pipes. Gas generated from the pump inflates the gasbag through the first through-holes, the first venting pipes, and the gas nozzles.
