Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of internal fistula protection, in particular to an internal fistula protection device to prevent blood seepage. Background Art
[0002] Arteriovenous fistula is one of the surgical operations, mainly used for hemodialysis treatment. Arteriovenous fistula is a minor operation of vascular anastomosis. The artery near the wrist of the forearm and the adjacent vein are sutured so that arterial blood flows in the anastomosed vein to form an arteriovenous fistula. The blood vessels of the arteriovenous fistula can provide sufficient blood for hemodialysis treatment and provide guarantee for the adequacy of dialysis treatment. Arteriovenous fistula is formed by free ligating and cutting the proximal end of the radial artery of the distal limb head vein to form an arteriovenous fistula. At present, patients undergoing arteriovenous fistula surgery need to use protective devices to protect the venous fistula.
[0003] However, since patients need to undergo arteriovenous dialysis at a fixed period, and each venous dialysis session is relatively long (generally four hours), protective devices need to be worn for a long time. Existing protective devices are directly tied to the patient's arm with Velcro or a tightening strap, which is in contact with the patient's arm skin for a long time, and is prone to leaving binding marks, reducing the overall comfort of the device. In addition, during the dialysis process, due to the rapid blood flow rate, if the patient's arm swings too much during dialysis, the dialysis catheter may become loose, resulting in fistula bleeding. Therefore, an anti-bleeding fistula protective device is proposed to solve the above technical problems. Utility Model Content
