Embodiment 1

[0048]

[0049] The preparation method is as follows:

[0050] 1. Mix the prescribed amount of polyvinyl butyral, glycerin, menthol, ethyl acetate, and 95% ethanol evenly, and stir for 1 hour at room temperature with a stirrer at a rotation speed of 800 rpm to prepare a mixed solution A.

[0051] 2. Mix the povidone-iodine, 30% hydrogen peroxide and purified water evenly in the prescribed amount, and stir for 15 minutes at room temperature under a stirrer with a rotating speed of 500 rpm to fully dissolve the povidone-iodine. Then add chitosan, and continue to stir at room temperature under a stirrer with a rotating speed of 800 rpm for 45 minutes, so that the chitosan is completely dissolved, and mixed solution B is made.

[0052] 3. Mix the solutions A and B evenly, stir for 15 minutes at room temperature under a stirrer with a rotating speed of 500 rpm, and adjust the pH to 3.0-4.0 to form a liquid wound dressing containing 10% povidone-iodine.

Embodiment 2

[0054]

[0055]

[0056] The preparation method is as follows:

[0057] 1. Mix the prescribed amount of vinylpyrrolidone / vinyl acetate copolymer, glycerin, menthol, ethyl acetate, and 75% ethanol evenly, and stir for 1 hour at room temperature with a stirrer at a speed of 800 rpm to form a mixed Solution A.

[0058] 2. Mix the povidone-iodine, 30% hydrogen peroxide and purified water evenly in the prescribed amount, and stir for 15 minutes at room temperature under a stirrer with a rotating speed of 500 rpm to fully dissolve the povidone-iodine. Then add chitosan, and continue to stir at room temperature under a stirrer with a rotating speed of 800 rpm for 30 minutes, so that the chitosan is completely dissolved, and mixed solution B is made.

[0059] 3. Mix solutions A and B evenly, stir for 15 minutes at room temperature under a stirrer with a rotating speed of 500 rpm, adjust the pH to 3.0-4.0, and then prepare a liquid wound dressing containing 5% povidone-iodine. ...

Abstract

The invention relates to the field of medical wound dressing, in particular to liquid bandage containing povidone iodine and a preparation method thereof, belonging to the technical field of medical treatment. The liquid bandage containing povidone iodine is characterized in that hydrogen peroxide is added into the formula of ordinary liquid bandage to achieve good effect. On one hand, hydrogen peroxide has very good hole forming effect on the liquid bandage, and hydrogen peroxide releases oxygen to achieve hole forming agent action through releasing a self disproportionated reaction.

Description

technical field [0001] The invention relates to the field of wound medical dressings, in particular to a preparation method of a liquid wound dressing, which belongs to the field of medical technology. Background technique [0002] Currently there are many products for wound care in the medical field, mainly in the form of transdermal patches. Although the existing traditional transdermal patch is easy to use and cheap. However, there are adhesive plasters, band-aids, which have relatively poor water absorption and air permeability, which is not conducive to the discharge of secretions and pus in the wound, and it is easy to cause bacteria to grow and reproduce, causing or aggravating infections, especially those that are prone to infection such as tetanus bacillus. Oxygenous bacteria; because the band-aid is fixed on the skin outside the wound through the adhesive layer, the wound cannot be completely isolated from the outside world more or less, and it is inevitable that ...
