Bioglass dressing used for promoting healing of cervix uteri wound and drug delivery device

Abstract

The invention discloses a bioglass dressing used for promoting the healing of the cervix uteri wound and a drug delivery device. For the bioglass dressing and the drug delivery device, the bioglass dressing comprises 45-70 % of an A component and 30-55 % of a B component, wherein the A component contains 3-20 % of bioactive glass (actimins), 55-70 % of medical liquid paraffin, and 3-10 % of polyethylene glycol; the B component contains 0.3-15 % of carboxymethyl chitosan, 0.05-3 % of sodium hyaluronate, 0.001-0.005 % of nano-silver ions, 60-80 % of purified water, and 5-15 % of polyving akohol. The A component and the B component are subjected to vacuum mixing under a specific condition to form gel, after the steps of high-temperature sterilization, disinfection and the like, the drug delivery device for the cervix uteri wound of the department of gynecology is well designed, and specifically, the gel is subjected to sterile filling; the bioactive glass is mixed with the functional components including silver ions, chitosan and the like, the scheme is applied to the medical apparatus for realizing drug delivery to the cervix uteri wound, through the manner of gel, the drug delivery is mild, the curative effects are obvious, the wound can be well covered, and the clinical problems that the powder delivery in the cavity is difficult and the powder has large irritation are solved.

Description

technical field [0001] The invention relates to the technical field of biomedicine, in particular to a biological glass dressing and a drug delivery device for promoting healing of cervical wounds. Background technique [0002] Tissue wound repair material, namely bioglass, is an inorganic synthetic amorphous powder containing natural elements of the human body such as silicon (Si), sodium (Na), calcium (Ca) and phosphorus (P), etc., and is used for bone defects Inorganic-induced silicon-based bioactive materials for repair and wound tissue repair. The products of Shandong Fengyuan Skin Health and Shanghai Sijian Te Skin Health are simple biologically active glass powders, which are directly sieved, sterilized and packaged. Jiangsu Yangsheng Biotechnology Co., Ltd.'s Demolin product simply combines bioactive glass (inorganic skin wound induction material) with medical vaseline to form a paste, and combines medical gauze and paste to form a dressing. [0003] Traditional ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a biological glass dressing and a drug delivery device for cervical wound healing, which are homogeneously stirred by components A and B respectively, and then vacuum stirred into a gel under specific conditions, and then sterilized by high temperature and other technologies, carefully design a gynecological cervical wound drug delivery device, which is made by aseptically filling the gel; there is no domestic device that combines bioactive glass with silver ions and chitosan and other functional ingredients for cervical wound drug delivery The medical device, through the way of gel, administers mildly, has significant curative effect, can cover the wound well, and solves the clinical problems of difficulty in administering powder in the cavity and excessive stimulation
