Abstract
A biological chitosan dressing is prepared from chitosan through spinning and weaving gauze. Its advantages are high antibacterial and antalgic function, high compatibility with human tissue, and high flexibility and air permeability.
Description
What technical field the present invention relates to is a kind of manufacture method of chitosan biological dressing, and the chitosan biological dressing is used for the treatment of wound.
Background technology dressing is a kind of being coated with on base material (being generally gauze) with medicine (also can not be coated with medicine sometimes), and it is topped on wound and wound is protected and the medical material of administration.Chitosan be found good antibiotic, hemostasis and with the fused function of tissue after, the chitosan biological dressing has obtained development in recent years.But the manufacture method of present chitosan biological dressing all is to be base material with film that chitosan is made.The produced chitosan biological dressing of this method shows defectives such as airtight, not soft, thereby is an impediment to the performance that the chitosan biological dressing should have superiority.
Summary of the invention is at these defectives, and purpose of the present invention is exactly that a kind of manufacture method that can produce the good chitosan biological dressing of good permeability flexibility will be provided.
The manufacture method of chitosan biological dressing provided by the invention is the base material that raw material is made the chitosan biological dressing with the chitosan, and its manufacture method is earlier chitosan to be made silk, makes gauze through weaving again.The base material that is to say the chitosan biological dressing is the gauze made from chitosan.
The manufacture method of chitosan biological dressing provided by the invention can apply molecular weight less than 5000 chitosan as further improvement project on the base material of chitosan biological dressing.Low-molecular-weight chitosan can individually or be painted on other drug on the base material of chitosan biological dressing with mixing.Low more helping more of the molecular weight of chitosan fuses with the quick of tissue.
The manufacture method of chitosan biological dressing provided by the invention, again it is woven into gauze after chitosan made silk, be exactly with chitosan with the form of gauze as medical dressing, good antibiotic, the hemostasis that makes that this chitosan biological dressing both had that its material itself embodied and with the fused function of tissue, had the softness that its structure embodied, characteristic such as ventilative again.As seen use that the chitosan biological dressing that manufacture method obtained of chitosan biological dressing provided by the invention is easier to carry out fused fast with tissue and bring into play better that it is antibiotic, the hemostatic effect.
The specific embodiment 1, be that 100,000 chitosan silk weaving becomes biological dressing with molecular weight.
2, be that 700,000 chitosan silk weaving becomes biological dressing with molecular weight, and to be coated with molecular weight in its one side towards wound be 3500 chitosan.
3, be that 500,000 chitosan silk weaving becomes biological dressing with molecular weight, and to be coated with molecular weight in its one side towards wound be 1200 chitosan.
4, be that 700,000 chitosan is 100,000 with enzymic degradation to mean molecule quantity with molecular weight, respinning is made into the chitosan biological dressing, and being coated with molecular weight is 2000 polysaccharide, and it is multiple to be used for applying of larger area wound.
Claims (2)
1, a kind of manufacture method of chitosan biological dressing is the base material that raw material is made the chitosan biological dressing with the chitosan, it is characterized in that this manufacture method is earlier chitosan to be made silk, makes gauze with silk through weaving again.
2, the manufacture method of chitosan biological dressing as claimed in claim 1 is characterized in that being coated with molecular weight less than 5000 chitosan on the base material of chitosan biological dressing.
