Description

Artificial vascular access

The present invention relates to a medical device; and more particularly to an artificial vascular access device having a hemostatic function.

With the advancement of medical technology, when the kidneys in the human body that are responsible for filtering blood function are damaged, hemodialysis (Hemodialysis) or peritoneal dialysis can be performed by an external filtering device, which is commonly called dialysis, so as to prevent the disease from being discharged due to waste of blood. Or death. At present, there are three main pathways for hemodialysis treatment of end-stage renal disease: autologous arteriovenous fistula, hemodialysis catheter, and artificial vascular arteriovenous fistula.

Among them, autologous arteriovenous fistula is a very good hemodialysis pathway, which can be used to make the autologous arteries and superficial veins surgically anastomosed, so that the autologous superficial veins produce high blood flow for puncture and hemodialysis. . However, ideal autologous blood vessels (especially autologous superficial veins) do not necessarily exist in every hemodialysis patient. Furthermore, after the establishment of the autologous arteriovenous fistula, it is necessary to go through a period of maturity and self-training of the patient, but it may not be mature. In addition, the mature arteriovenous fistula must be removed after the needle is removed. Manual compression to stop bleeding, if improperly applied, may lead to excessive bleeding or fistula embolization, and the fistula is repeatedly puncture, easy to form an aneurysm over time, further leading to bleeding risk.

In the foregoing case, the use of a hemodialysis catheter is often the last option for a hemodialysis pathway. In actual use, the front end of the hemodialysis catheter can be placed percutaneously into the central vein, and the front end opening can be adjusted to a proper position by radiographic imaging. When the catheter is placed in the human body, the large blood vessel and the lungs can be puncture. Risk of massive bleeding; moreover, blood is trapped in the catheter At the time, it is easy to cause embolism, such as: the catheter is placed in the central vein, often causing central vein stenosis or blockage. In addition, the open end of the catheter-connected hemodialysis machine circuit protrudes beyond the body surface, which not only affects the appearance and living, but also easily causes infection.

Therefore, the human main vascular arteriovenous fistula is an alternative to the failure of the autologous arteriovenous fistula. The artificial vascular graft is implanted mainly in the subcutaneous tissue of the patient, and the artificial blood vessel is interposed between the autologous artery and the vein, and the ends of the artificial blood vessel are respectively anastomosed with the autologous artery and vein. After the subcutaneous tissue is completely covered with the artificial blood vessel (about three weeks), the blood is transfused by the artificial blood vessel, the blood in the artery of the patient is output to the hemodialysis instrument for filtration, and the filtered blood is input into the vein of the patient. . Among them, the conventional artificial blood vessel will bleed after puncture, and the artificial blood vessel must be pressed by human force during the hemostasis. The embodiment can refer to the patent cases such as "Artificial Blood Vessel" of the Republic of China Announcement No. 476652 and "Artificial Vascular Structure" of No. M372181.

However, the hemostasis of traditional artificial blood vessels varies from person to person according to the pressure channel. If the pressure channel is too small, the blood cannot be stopped. If the pressure channel is too large, the artificial blood vessel will be deformed and blocked, and the patient will be dialysis for a long time (eg, 3 per week). In the course of treatment, it is inevitable that the artificial blood vessel will be deformed due to compression and hemostasis, causing blood flow of the artificial blood vessel to be blocked or permanently damaged, which may cause discomfort to the patient. In severe cases, it may be necessary to re-implant a new artificial blood vessel. Make the patient miserable.
