Anti-inflammatory and hemostatic dressing, preparation method thereof, PICC catheterization and CVC catheterization

Abstract

The invention belongs to the technical field of degradation products or derivatives of proteins and polypeptides, and discloses an anti-inflammatory and hemostatic dressing and a preparation method thereof, a PICC catheterization and a CVC catheterization. The anti-inflammatory and hemostatic dressing is prepared from IV3000 transparent dressing 4008. The traditional Chinese medicine extract is added into the anti-inflammatory and hemostatic dressing provided by the application, so that the anti-infection and hemostatic effects are improved, the catheterization time can be prolonged, and related complications such as retrograde blood flow infection, local infection and bleeding caused by catheterization can be reduced. In the anti-inflammatory hemostatic dressing, an IV3000 transparent dressing 4008 is adopted as the anti-inflammatory and hemostatic dressing, and the anti-inflammatory and hemostatic dressing has the characteristics of good air permeability and moderate size. Absorbableregenerated oxidized cellulose (SURGICEL SNoWAbsorbable Hemostat) has a hemostatic adjuvant for controlling local bleeding, and has the effect of killing multiple types of gram-positive and gram-negative microorganisms in vitro, including aerobic bacteria, anaerobic bacteria and the like.

Description

technical field [0001] The invention belongs to the technical field of proteins and polypeptides; their degradation products or derivatives, and in particular relates to an anti-inflammatory hemostatic dressing and a preparation method thereof, and PICC and CVC catheters. Background technique [0002] At present, the existing technology commonly used in the industry is as follows: in recent years, the incidence of tumor diseases and blood diseases has increased year by year, and more and more patients have received radiotherapy and chemotherapy, but radiotherapy and chemotherapy have great damage to peripheral blood vessels, so PICC The number of patients with catheterization and CVC catheterization has also increased year by year. In addition, there is an aging population, and more patients use PICC catheters and CVC catheters for parenteral nutrition therapy. PICC catheters and CVC catheters are placed in large blood vessels for a long time, which can easily cause infecti...

AI Technical Summary

Problems solved by technology

[0003] To sum up, the problems existing in the prior art are: PICC catheters and CVC catheters are placed in large blood vessels for a long time, which is likely to cause infection and bleeding at the puncture site; Contact is easy to cause allergies, poor comfort, lack of anti-infection and hemostatic effects
