Problems solved by technology

However, traditional hydrocolloid dressings generally cannot be used for wounds with more exudate, because the absorption efficiency of traditional hydrocolloid dressings for exudate is not very fast, so that it is too late to absorb completely for wounds with more exudate, making the exudate Spillage, damage to surrounding skin

Abstract

The invention relates to the technical field of medical materials, and discloses a hydrocolloid and a hydrocolloid dressing and a preparation method thereof. The hydrocolloid includes a thermoplasticelastomer, sodium carboxymethyl cellulose, lanolin, sodium hyaluronate, and liquid paraffin. The lanolin and the sodium carboxymethyl cellulose and the like are added to the hydrocolloid to significantly increase the liquid absorbing property, so that the hydrocolloid can be applied to a highly-exudative wound dressing, and the problem that seepage of a traditional hydrocolloid dressing is easy toleak to cause damage to the surrounding skin can be avoided.

Description

technical field [0001] The invention relates to the technical field of medical materials, in particular to a hydrocolloid, a hydrocolloid dressing and a preparation method thereof. Background technique [0002] Medical dressings made of natural or synthetic biological materials are called medical biological dressings. In recent years, with the rapid development of modern science and technology, the research on medical dressings has also developed rapidly. A variety of new medical dressings emerge in an endless stream, and their performance is getting better and better. The so-called medical dressing is a common type of medical material used for temporary covering of wounds and wound surfaces. This medical material can also avoid bacterial infection and external factors that affect the wound. Good protection. For patients with extensive burns, wound infection is still the most important cause of burn death. Therefore, it is necessary to search for an ideal wound covering t...
