Problems solved by technology

[0002] Arteriovenous fistula (Arterio-venous Fistula, AVF) is currently the most ideal and most widely used permanent vascular access for hemodialysis patients. Dialysis patients are punctured 3 to 4 times a week, which will inevitably cause damage to the vascular intima , lead to internal fistula stenosis, thrombosis, pseudoaneurysm, pain, bleeding, hematoma and infection and other complications. For the treatment of internal fistula to promote blood circulation and remove blood stasis, reduce swelling and relieve pain, there are measures such as smearing with Hirudoid, external application of potato slices, etc. However, these schemes must avoid the puncture needle site, and can only be used as preventive protection measures when the blood vessels of the patient are not damaged or have no obvious scar formation. It is difficult to maintain the function of AVF when there are serious complications such as induration

Abstract

The invention discloses a hydrophilic polymer gel layer and the prepared Chuanhong Tongluo Patch. The hydrophilic polymer gel layer is a hydrophilic polymer gel containing safflower, Chuanxiong, red peony, holly and peppermint. A kind of Chuanhong dredging collateral patch made by utilizing a hydrophilic polymer gel layer, comprising a heating bag, a fixed layer, an anti-adhesive protective layer and the hydrophilic polymer gel layer, one side of the fixed layer A heating bag is fixed, the other side is coated with a hydrophilic polymer gel layer, and the hydrophilic polymer gel layer is covered with an anti-adhesive protective layer. The Chuanhong Tongluo patch of the present invention has good air permeability, no sensitization, irritation, easy and comfortable use, has the effects of dispelling blood stasis and relieving pain, dilating blood vessels, increasing blood flow, improving microcirculation, inhibiting platelet aggregation and preventing infection, especially It will be more effective for scarring, induration, spasm, damage, intimal hyperplasia, tenderness or cord induration of the skin at the arteriovenous fistula.
