Problems solved by technology

Some disinfection products have a short effective time, and harmful substances such as bacteria and viruses will reappear in a short period of time.
In addition, existing disinfection products do not have a broad spectrum, and can only kill one of viruses, bacteria, and fungi, or can only kill specific types of viruses or bacteria

Embodiment 1-4

[0036] In Examples 1-4, the quality added by each component is shown in Table 1, the operation step is: the method of testing the mass of the polyvinyl alcohol (molecular weight of 2.5 ~ 35,000), Ortennidine and water, stir mix Uniform, an anti-infective spray dressing can be obtained.

[0037] Table 1

[0038]

Embodiment 5

[0040] The anti-infective spray dressing prepared in Example 1 was placed under ultraviolet light for 30 min, and then the irradiated anti-infective spray dressing was tested using a nano-laser tester. The particle size of the anti-infective spray dressing did not change. It shows that the anti-infective spray dressing in the present application has good light insensibility.

[0041] The anti-infective spray dressing prepared in Example 1 was exposed in the thermal environment, waiting for one day, no fire star appeared, indicating that the anti-infective spray dressing point in the present application is high, and the application range is wide.

Embodiment 6

[0043] Examples 1 to Example 4 were used for clinical experiments. The experimental method was: use anti-infective spray dressings to spray at 10 cm from the invasive wound (burns), three times a day, observed After 15 days of traumatic wounds, there is a big improvement.

Abstract

The invention discloses an anti-infection spray dressing as well as a preparation method and application thereof, and belongs to the technical field of medical supplies. The anti-infection spray dressing comprises an enol polymer, octenidine and a solvent, in the anti-infection spray dressing, the mass content of the octenidine is 0.06% to 0.5%. According to the anti-infection spray dressing as well as the preparation method and application thereof, the anti-infection spray dressing has the advantages of long aging, light insensitivity, difficulty in hydrolysis, high ignition point, wide-range pH stability and the like, so that the anti-infection spray dressing is easy to store, the disinfection effect is not easily influenced by the external environment, and the efficacy is continuous.

Description

Technical field [0001] The present invention relates to an anti-infective spray dressing and a preparation method thereof, an application, a technical field of medical supplies. Background technique [0002] There are certain problems in current disinfection products, such as the characteristics of wine exquisite volatile, resulting in difficulties, and the sterilization effect will be reduced after the concentration changes. Most disinfection products have corrosive, so it is not suitable for treating damaged skin, such as cutting, rubbing, burn, etc. The corrosive disinfection products are also used as direct contact with disinfection products because of the use of skin mucosa. Some disinfection products have a short time, and there will be a bacteria, viruses such as bacteria and viruses in a short period of time. In addition, existing disinfection products do not have broad-spectrum, only for the virus, bacteria, and fungi, or only kill specific species of viruses or bacteria...
