[0282] 1. Effect of different solvent systems on the solubility of iodine complexes

[0283] Take several 10mL vials, weigh (select) respectively 2g of polyvinylpyrrolidone iodine (povidone iodine), methionine iodine, iodine PEG iodine, and double-chain quaternary ammonium salt iodine. The bottles are respectively coded as A-X, B-X, C-X, D-X four series, after adding 10mL of solvents of different systems, observe the solubility and viscosity and record, secondly, cover the bottle mouth with absorbent cotton cloth, place it at about 60°C overnight, and observe the color change of the cotton cloth.

[0284] The results show that povidone iodine and methionine iodine have good solubility in water, and iodine PEG iodine and double-chain quaternary ammonium salt iodine can be mixed evenly in ethanol and isopropanol. The iodine cloth is slightly yellow, and it is inferred that there may be a slight volatilization of iodine.

[0285] Taking A-X as an example, the test grouping, form...

Embodiment 1

[0414] When the principal agent is polyvinylpyrrolidone iodine (povidone iodine) and polyvinyl alcohol iodine, its basic preparation process is as follows:

[0415] Preparation of the drug-loading system: take the prescribed amount of iodine-complex, adhesive (optional), stabilizer (optional), softener and volatile solvent, mix and dissolve, and store in the dark;

[0416] Drug-loaded cloth: select the type of cloth listed in the prescription, which can be pre-punched and cut according to requirements;

[0417] The basic process of the process: After the liquid medicine is prepared, it is implanted in the tank or placed in the spraying container, and the cloth is immersed for 0.5-1min (or evenly sprayed), after the adsorption is saturated, it is left for a while to empty part of the liquid medicine, and can be introduced into the rolling mill to remove part of the liquid Or do not process, and process in a dryer to get the final drug-loaded cloth.

[0418] Cut according to ne...

Embodiment 2

[0466] When the principal agent is double-chain quaternary ammonium salt iodine, methionine iodine and polyethylene glycol iodine (PEG-I) etc., the compound of iodine adopted has no adhesion, and its basic preparation process is as follows:

[0467] Preparation of the drug-loaded system: take the prescribed amount of iodine-complex, adhesive, stabilizer (optional), softener and volatile solvent, mix and dissolve, and store in the dark;

[0468] Drug-loaded cloth: select the type of cloth listed in the prescription, which can be pre-punched and cut according to requirements;

[0469] The basic process of the process: After the liquid medicine is prepared, it is implanted in the tank or placed in the spraying container, and the cloth is immersed for 0.5-1min (or evenly sprayed), after the adsorption is saturated, it is left for a while to empty part of the liquid medicine, and can be introduced into the rolling mill to remove part of the liquid Or do not process, and process in ...

Abstract

The invention discloses breathable iodine compound-containing hydrophilic antibacterial and antiviral medical cloth. The breathable iodine compound-containing hydrophilic antibacterial and antiviral medical cloth mainly comprises medical cloth and a drug-loading solvent system, wherein the drug-loading solvent system further comprises an iodine compound and a drug-loading auxiliary material; the iodine compound mainly refers to one or a mixture of methionine iodine, polyvinylpyrrolidone iodine, polyvinyl alcohol iodine, polyethylene glycol iodine, polyol ether iodine and the like; the drug-loading auxiliary material mainly comprises a volatile solvent, an adhesive, a stabilizer and a softening agent; and the medical cloth comprises degreasing cotton cloth or a hydrophilic non-woven fabric and the like. A basic preparation process comprises the following steps of preparing the drug-loading solvent system, embossing or punching the medical cloth, then carrying out soaking, spraying or padding process treatment, and finally carrying out drying or airing, and carrying out storing in a dark place. The drug-loading cloth can be mainly used as a mask, a protective garment, a protective layer of an open wound and the like.

Description

technical field [0001] The invention relates to the research in the field of medical materials, in particular to the composition, preparation method and application of a breathable hydrophilic iodine complex-loaded antibacterial and antiviral medical cloth. Background technique [0002] For thousands of years, during surgical operations, epidemics, and clinical needs of traditional Chinese medicine, doctors have never stopped screening and researching on cloth with special functions or medicinal effects, such as breathable, antibacterial, antiviral, anti-adhesion, and protection against secretions. Hot words such as absorption and even implantable degradation are repeatedly pursued and expanded. In recent years, medical fabrics with special functions have become more refined, but their characteristics have become more prominent, and frontier research has progressed rapidly, but there are more shortcomings, which makes the projects that can be produced on a large scale very f...
