Description

TECHNICAL FIELD

[0001] The utility model relates to hemodialysis protection frame technical field, specifically is hemodialysis arteriovenous fistula protection frame. BACKGROUND

[0002] Hemodialysis: is one of the kidney replacement therapy of acute and chronic renal failure patients. It is through the body blood is drained to the outside, in a by countless hollow fibers composed of dialyzer, blood and the body concentration similar electrolyte solution (dialysate) in a root root hollow fiber inside and outside, through the dispersion, ultrafiltration, adsorption and convection principle carries on the material exchange, removes the metabolic waste in the body, maintains electrolyte and acid-base balance; At the same time, remove the excess water in the body, and the whole process of the purified blood back into.

[0003] Autologous arteriovenous fistula (arteriovenous fistula, AVF), refers to the subcutaneous distance close to a certain artery and superficial vein vascular communication through surgery, artificial formation of in vivo arteriovenous direct access pipeline, the purpose is to take advantage of the superficial vein on one hand, the advantage of easy to puncture, on the other hand, through the direct blood supply of artery, make superficial vein blood flow increase to achieve the required treatment. As the preferred vascular access of uremic patients receiving maintenance hemodialysis treatment.

[0004] Arteriovenous graft (arteriovenous graft, AVG), refers to the implantation of graft between artery and vein, artificial connection of arteriovenous, is one of the most commonly used vascular access for long-term hemodialysis patients.

[0005] Maintenance hemodialysis (MHD) is one of the main treatment methods for treating end-stage renal disease, and the types of hemodialysis access mainly include arteriovenous fistula (AVF), arteriovenous graft (AVG) and central venous catheter (CVC). When AVF and AVG are used for hemodialysis, dialysis puncture needles are needed to be punctured, and blood is drained out of the body through an extracorporeal circulation pipeline, and then returned to the patient's body after dialysis purification. The conventional dialysis time is about 4h each time, and the patient spends the time sleeping. During the dialysis process, the catheter connected to the arteriovenous fistula is often exposed or covered by a treatment towel. There is a lack of effective protection and fixation. Unintentional activities of the patient, such as scratching and bending the arm, can easily cause the blood vessel to be punctured, the emergency machine to be stopped, the dialysis pipeline to be replaced, and other accidents, increase the dialysis cost, and in severe cases, cause the dialysis pipeline to be pulled out, the patient to lose a lot of blood, and the life safety to be endangered. At present, the dialysis centers use treatment towels to cover the arteriovenous fistula on the dialysis side, and use hemostats to clamp the pipeline on the patient's clothes, which lacks effective protection. The similar device on the market is a transparent polycarbonate protective cover similar to an arm. After the hemodialysis starts, the protective cover is placed above the arteriovenous fistula on the dialysis side to avoid external objects from invading the puncture site and to facilitate observation.
