Embodiment Construction

[0011] from figure 1 From the schematic cross-sectional structure of the present invention, it can be seen that the present invention includes a functional layer 1 made of seaweed fibers loaded with nano drug-loaded capsules, a protective layer 3 and a base layer made of absorbent core layer 2 . Its production method is as follows:

[0012] Step 1: blending alginate drug-loaded capsules with sodium alginate spinning liquid, using spinning equipment, using calcium chloride solution as a coagulation bath, and preparing seaweed fibers loaded with nano drug-loaded capsules by wet spinning. Add sodium alginate to deionized water to obtain sodium alginate solution, add Ca(OH)2 solution and NaHCO3 solution dropwise to sodium alginate solution, wherein sodium alginate: Ca(OH)2: NaHCO3 The mass ratio is 125:3.7:6.3. After adding NaHCO3 solution and stirring, add methylene blue solution, wherein the mass ratio of sodium alginate:methylene blue is 125:1, then collect by centrifugal wash...

Abstract

The invention discloses a sustained drug release type medicine dressing. Sodium alginate drug carrying capsules and a sodium alginate spinning solution are blended, spinning equipment and wet spinning are utilized for preparing alginate fibers carrying nano drug carrying capsules, a basic layer is composed of a protection layer and an absorption core layer, and a functional layer prepared from the alginate fibers carrying the nano drug carrying capsules and the basic layer are prepared into the sustained drug release type medicine dressing through spunlace processing. Hemostasis, bacterium resistance and adhesion prevention are achieved, the moisture preserving effect is good, the healing speed is high, and the sustained drug release type medicine dressing can be used for treating and protecting a variety of wounds.

Description

technical field [0001] The invention belongs to the field of medical technology, in particular to a drug slow-release medical dressing. Background technique [0002] Ordinary dressings are not suitable for acute and chronic wound healing due to their slow healing rate. In order to shorten the healing time of wounds as much as possible, biomedical dressings or active dressings have received more and more attention. Drug-loaded dressings are only required to contain novel chemical drugs of some therapeutic value, while also addressing the shortcomings of traditional topical drug formulations. Drugs added to medical dressings play an important role in the wound healing process, which can directly or indirectly clean the wound and remove necrotic tissue; as an antibacterial agent, prevent or treat bacterial infection; as a growth agent, promote tissue regeneration; as Supplements accelerate wound healing; in addition, in order to enable the drug to continuously and stably act ...
