Cardiac monitor

The present invention provides an information acquisition device, comprising: a cushion for supporting a subject to be tested; a neck pillow for the subject to be tested to place his neck thereon; a fiber-optic sensor group for obtaining physical signs of the subject to be tested; and a signal acquisition module connected to the fiber-optic sensor group; wherein the signal acquisition module is wrapped in the neck pillow, the fiber-optic sensor group is placed in the cushion, and the neck pillow is connected with the cushion. In the present invention, by setting a neck pillow connected with the cushion so that the subject can adjust the body position independently without assistance to a preferred measurement position, and can complete information acquisition by himself. In addition, the signal acquisition module is placed in the neck pillow, so that the structure of the information acquisition device is more concise.

An occluder includes a first occluder disc, a second occluder disc, a waist portion connecting the first occluder disc and the second occluder disc, and at least one soft and fibrous strand bundle structure. The strand bundle structure is disposed on at least one of a disc surface of the first occluder disc and a disc surface of the second occluder disc, the two disc surfaces faces each other, and the strand bundle structure is disposed near the waist portion. By disposing the strand bundle structure to be immediately adjacent to the waist portion, a defect opening can be occluded after implantation, thereby effectively blocking blood from flowing from one side of the defect to the other side thereof, and preventing a shunt from being formed.
