Abstract

The present invention relates to the technical field of electrospinning, more specifically, to an electrospinning tubular support collection device and electrospinning equipment, including a support frame and a collector rotatably connected to the support frame, and the collector includes a split tubular structure and a Coupling used to constrain the split tubular structure, the coupling is detachably connected to both ends of the split tubular structure; one end of the split tubular structure is connected to a transmission mechanism, and the transmission mechanism is connected to a drive motor; the split tubular structure is conductive Structure, the split tubular structure is applied with a negative voltage, and the fibers formed by the splitting of the charged jet released from the positive voltage end are oriented and collected on the outer surface of the split tubular structure due to the action of the electric field force. The split-type tubular structure of the present invention is a cylinder under the fixation of the coupling. After the coupling is released, the split-type tubular structure is separated, and the tubular support can be easily taken out without destroying the original appearance of the tubular support. Solved the problem that the tubular stent was difficult to take out.

Description

technical field [0001] The invention relates to the technical field of electrospinning, and more specifically, to an electrospinning tubular support collection device and an electrospinning device. Background technique [0002] Cardiovascular disease is one of the main causes of human death, especially coronary artery disease accounts for 53% of the total mortality of cardiovascular disease, surgical replacement or bypass grafting is the main means of treatment of coronary artery and other diseases. Autologous blood vessels and artificial synthetic blood vessels are the main clinical vascular grafts, but the sources of autologous blood vessels are limited, and it is difficult to meet clinical needs. Vascular tissue engineering technology provides a new source of small-diameter vascular grafts. The idea is to use the combined culture of vascular cells and degradable scaffolds to construct biologically active and functional small-diameter vascular substitutes. Degradable scaf...
