An intra-aortic dual balloon driving pump catheter device having a catheter; a first balloon and a second balloon respectively surrounding the catheter, being arranged successively along the longitudinal direction of the catheter, wherein the position of the first balloon is placed at the distal end of the catheter, and the second balloon is placed immediately adjacent to the proximal end of the first balloon; the first balloon and the second balloon are periodically expanded to a dimension that nearly blocks the aortic blood flow and contracted to a dimension that does not prevent the blood flow from passing through; wherein the first balloon periodically inflates in diastole and deflates in systole working as a pump, while the second balloon conversely deflates in systole and inflates in diastole functioning as a valve, altogether leading to blood pumping from contracting ventricle and keeping driving forward ahead in the aorta.

Intra-aortic dual balloon driving pump catheter device

The present application relates to the technical field of industrial data processing, and in particular relates to a field data processing method, apparatus and system, which are used to realize the timely processing of field data. In the embodiments of the present application, a field data processing apparatus located on an industrial site of an industrial system receives field data from at least a field apparatus on the industrial site, and processes the received field data and provides the processing result of the field data. In this way, untimely processing of field data can be avoided.
