Remote control built-in internal arteriovenous fistula maturing using device and operating principle thereof

Abstract

The invention discloses a remote control built-in internal arteriovenous fistula maturing using device and an operating principle thereof, and relates to a blood vessel maturing using device. The remote control built-in internal arteriovenous fistula maturing using device comprises a drug eluting stent (1), an anti-freezing outer layer (2), a remote control device (3), two puncture needles (4), a puncture outfit (5) and a remote controller (6). The anti-freezing outer layer (2) is arranged on the outer side of the drug eluting stent (1), the remote control device (3) is arranged on the inner side of the drug eluting stent (1), the puncture outfit (5) is arranged on one side of the remote control device (3) and is connected with the remote control device (3), the two puncture needles (4) are symmetrically arranged on the puncture device (5), and the remote controller (6) is wirelessly connected with the remote control device (3). The remote control built-in internal arteriovenous fistula maturing using device has the advantages of being safe, convenient to use, few in blind puncture times and infection opportunity, capable of automatically promoting blood vessel internal fistula to mature and the like.

Description

technical field [0001] The invention relates to a device for ripening blood vessels, in particular to a remote control implantable device for maturing arteriovenous fistula and its working principle. Background technique [0002] For patients with end-stage renal disease, maintenance hemodialysis is the main alternative therapy, and the arteriovenous fistula as a "lifeline" is the most commonly used vascular access for maintenance hemodialysis. However, for elderly patients, diabetic patients, or patients with poor vascular conditions, although venous fistula can be performed, the probability of postoperative internal fistula failure is high, or it is abandoned because the blood flow cannot meet the requirements of dialysis . Thrombosis and vascular occlusion are common causes of this problem. If the thrombus is found, surgery is usually performed to remove the thrombus or to perform a new operation. The patient needs to bear the surgical risk and financial burden again, w...

However, for elderly patients, diabetic patients, or patients with poor vascular conditions, although venous fistula can be performed, the probability of postoperative internal fistula failure is high, or it is abandoned because the blood flow cannot meet the requirements of dialysis

Thrombosis and vascular occlusion are common causes of this problem. If the thrombus is found, surgery is usually performed to remove the thrombus or to perform a new operation. The patient needs to bear the surgical risk and financial burden again, which has a great impact on the patient's body and mind.
