Background
The arteriovenous internal fistula refers to a small operation for blood vessel anastomosis, wherein an artery at the part of a forearm close to a wrist and an adjacent vein are sutured, so that arterial blood flows in the anastomosed vein to form an arteriovenous internal fistula. The arteriovenous internal fistula has the advantages that the blood vessel can provide sufficient blood for hemodialysis treatment, provides guarantee for the sufficiency of the dialysis treatment, and is a life line of a patient receiving the dialysis treatment.
However, arteriovenous internal fistula has some defects, and when patients suffer from hypotension, hyperlipidemia, hypercoagulability, infection, diabetes and other primary diseases, the internal fistula is easy to cause occlusion, which is related to the fact that the disease per se is easy to cause the pathological changes of peripheral blood vessels. In addition, the postoperative and maintenance nursing are not proper, the postoperative operation side of the patient lacks functional exercise, and the body compresses the operation side when the postoperative binding is too tight or in a lying position; when in use, the same part is punctured repeatedly, and the internal fistula is blocked due to overlong compression time after dialysis, so that the function of the fistula can not be realized.
Therefore, the blood flow speed at the arteriovenous internal fistula of the patient needs to be monitored, if the blood flow is too slow, the arteriovenous internal fistula has a blockage risk, and measures need to be taken to eliminate thrombus so that the arteriovenous internal fistula is smooth; the normal intra-arterial blood flow is fast, the intra-venous blood flow is slow, the blood flow at the internal arteriovenous fistula is directly flushed into the vein by arterial blood to form turbulent flow, and whether the blood flow at the internal arteriovenous fistula is smooth or not can be further confirmed through the turbulent flow; however, the blood flow velocity monitoring can only be carried out in hospitals by reserving Doppler color ultrasonography at present, and in addition, turbulence at the internal arteriovenous fistula can only be judged simply by listening to vibration sound or touching vibration, and a large error exists; the real-time monitoring of the arteriovenous internal fistula after the operation of the patient can not be realized under the restriction of the conditions.
