Abstract: A removable wrist device in a continuous physiological monitoring system includes a mounting fixture with a pair of rails to securely retain another device, such as a battery, a watch, or a display. The rails may be curved to secure the device against displacement during purely translational movement while conveniently conforming to the shape of a wrist. At the same time, the rails can permit movement around the axis of the wrist (where significant rotational forces are not regularly encountered) to permit convenient attachment and removal of the other device to the wrist-mounted device through a rotational, sliding motion. This configuration provides an advantageous combination of ease of use (sliding on and off in a natural motion), mounting tenacity, and comfort.
