  • Patent number: 11737676
    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.

  • Patent number: 11717212
    Abstract: Disclosed are embodiments describing finger calipers with a pair of lever arms pivotally attached to a hand plate via a pivot point at their respective proximal ends. Each of the lever arms extend along the length of a finger and attach to the end of the respective finger via a finger cuff or some other attachment means. Accordingly, the lever arms can open and close, or otherwise splay apart, in a scissor like manner when the fingers that they are attached to open and close or otherwise splay apart. A ratchet system comprised by one of the lever arms and the hand plate allow for one-way motion of the ratcheted lever arm. The other lever arm freely pivots across the hand plate. When a medical examiner is using the finger calipers, they can reliably measure a dilated cervix by reading a corresponding dilation measurement indicium associated with the ratcheted lever arm.
