Description

Balloon inflation volume self-adaptive control system and method
Technical Field
The invention relates to the field of arterial blood vessel treatment, in particular to a balloon inflation volume self-adaptive control system and method.
Background
The arteries in western medicine are blood vessels that carry blood away from the heart, and after exiting from the ventricles, branch repeatedly, become thinner and thinner, and finally travel to capillaries. The wall of the artery is thick, and can bear large pressure. The aorta wall has more elastic fibers and larger elasticity, the wall expands when the ventricle shoots blood, and the wall retracts when the ventricle relaxes, so that the blood continues to flow forwards. The smooth muscle of middle and small artery, especially small artery wall is developed, and it can contract or relax under the regulation of nerve fluid to change lumen and size, and affect local blood flow resistance. The flow rate of the blood is fast.
The structural features of dynamic blood vessels are as follows: the intima consists of endothelium, subendothelial layer, and internal elastic membrane. The subendothelial layer is located outside the endothelium and is a relatively thin, loose connective tissue that contains a small number of smooth muscle fibers. The inner elastic membrane is made of elastin and has a plurality of small pores. On the cross section of the middle artery, the inner elastic membrane is waved due to the contraction of the vessel wall and can be used as the boundary between the inner membrane and the middle membrane; the tunica media is thick and mainly consists of 10-40 layers of smooth muscles, so the tunica media is called muscular artery; there are a few elastic and collagen fibers between the smooth muscles. The smooth muscle fiber can control the size of the pipe diameter and regulate the blood flow of the organ. In addition, smooth muscle fibers have the function of producing connective tissue and stroma; the outer membrane is similar in thickness to the middle membrane and is composed of loose connective tissue. The interface between the adventitia and the media is separated by an external elastic membrane, and the small blood vessels and lymphatic vessels are distributed in the adventitia.
