Preparation method of medical hemostatic occlusion dressing

Abstract

The invention discloses a preparation method of a medical hemostatic occlusion dressing. The preparation method comprises the following steps: (1), taking and pouring deionized water into a reactor, heating the reactor, slowly adding lemon peel pectin and gelatin, and mechanically stirring at the same time; (2), after the addition of the lemon peel pectin and gelatin, stirring continuously, then adding other components into the reactor, and carrying out mechanical stirring uniformly at the same time; (3), after the mixing of the materials, cooling hydrogel to be at a room temperature, so as to obtain the medical hemostatic occlusion dressing. The medical hemostatic occlusion dressing prepared through the method provided by the invention is high in bleeding stopping speed, has auxiliary functions of promoting wound surface healing, preventing adhesion and the like, is also better in biomechanics and air permeability, and has an important clinical application value; the preparation method provided by the invention has the advantages that the process is simple, requirements for equipment are relaxed, raw materials are low in cost and readily available, the cost is low, and industrialization is easy to realize.

Description

technical field [0001] The invention belongs to the field of new medical materials and relates to a preparation method of a medical hemostatic occlusion dressing. technical background [0002] Antibacterial hemostasis has always been a problem often encountered in hospital operations, and it is also a difficult problem often encountered in daily life. Medical dressing is a medical product used to cover burns, wounds, ulcers and other wounds, so that it temporarily plays a part of the skin barrier function, providing an environment conducive to wound healing, waiting for the epithelialization of the wound or transition to permanent reconstruction skin barrier. With the in-depth study of the pathophysiology of the wound healing process, people's understanding of the wound healing process is becoming more and more profound, thus promoting the continuous improvement and development of wound dressings. Today, new wound dressings have undergone revolutionary changes compared to ...

Problems solved by technology

In the past ten years, breakthroughs have been made in the research of dressings, but there are still some defects such as poor biocompatibility with the skin, which is not conducive to reducing wound pain and promoting wound healing. Adhesion, causing damage to the new tissue during removal, causing great pain to the patient
