5 is a cross-sectional view taken along the line VV ′ of FIG. 1.

Referring to FIG. 5, the skin improvement treatment device (100 of FIG. 1) using a portable LED according to an embodiment of the present invention is coated with an antimicrobial coating layer 150 on the outer surface of the treatment body (110 of FIG. 1). ) May be further included.

At this time, the antimicrobial coating layer 150 includes silver colloid powder: 30 to 45 parts by weight and dispersion stabilizer: 10 to 15 parts by weight based on 100 parts by weight of the natural antimicrobial agent. In addition, the antimicrobial coating layer 150 may further include 3 to 7 parts by weight of N-isopropylmethacrylamide, based on 100 parts by weight of the natural antimicrobial agent.

Natural antibacterial agents are added for the purpose of preventing infection of the therapeutic body, including the front case 112 and the rear case (114 in FIG. 1) from bacteria. Natural antibacterial agents may be used extracts extracted from natural antibacterial substances. As a natural antimicrobial agent, one or more selected from cinnamaldehyde, polylysine, rosemary oil, aryl isothiocyanate, and the like may be used.

Silver is added together with the natural antimicrobial agent for the purpose of enhancing the antimicrobial effect. In particular, the silver colloid powder has excellent antibacterial properties and is a toxic substance that is harmless to humans or living bodies as a food additive. When the addition amount of silver colloid powder is less than 30 weight part with respect to 100 weight part of antimicrobial coating layers, since the addition amount is insignificant, an antimicrobial effect cannot be exhibited properly. On the contrary, when the addition amount of silver colloid powder exceeds 45 parts by weight, it is not economical because the synergistic effect is small compared to the addition amount.

Dispersion stabilizers are added for the purpose of inducing proper mixing of the additive materials. As the dispersion stabilizer, P-Phenylene diisocyanate may be used. When the addition amount of the dispersion stabilizer is less than 10 parts by weight with respect to 100 parts by weight of the antimicrobial coating layer, the dispersion effect cannot be properly exhibited. On the contrary, when the addition amount of the dispersion stabilizer exceeds 15 parts by weight with respect to 100 parts by weight of the antimicrobial coating layer, only the manufacturing cost is increased without any additional effect.

In the present invention, N-isopropylmethacrylamide is preferably added in 3 to 7 parts by weight based on 100 parts by weight of the antimicrobial coating layer. When the addition amount of N-isopropyl methacrylamide was less than 3 weight part with respect to 100 weight part of antimicrobial coating layers, the antimicrobial effect was insignificant. On the contrary, when the addition amount of N-isopropyl methacrylamide exceeds 7 weight part with respect to 100 weight part of antimicrobial coating layers, the synergistic effect compared with the addition amount is insignificant and it is not economical.

Therefore, the skin improvement treatment device using the portable LED according to the present invention has an effect of blocking propagation or infection of bacteria by an antimicrobial coating layer coated on the surface of the body of the treatment device including a front case and a rear case. It is hygienic.

20 g of cinnamaldehyde, 9 g of silver colloid powder, 2.5 g of P-Phenylene diisocyanate and 60 ml of distilled water were added to a high speed mixer, followed by stirring for 30 minutes at 1200 rpm, followed by mixing at 120 ° C. Drying for minutes gave an antimicrobial coating.

Thereafter, ⁴ g of the sample obtained by cutting the antimicrobial coating agent and E. coli having an initial concentration of 1.6 × 10 ⁴ were added to seal the test tube, and after 24 hours, the concentration of E. coli remaining in the test tube was measured using a detection tube. Escherichia coli ATCC 25922 was used as a strain of E. coli.

Example 2

An antimicrobial coating agent was prepared in the same manner as in Example 1 except that 7 g of silver colloid powder was added, and then the concentration of E. coli was measured.

Example 3

An antimicrobial coating agent was prepared in the same manner as in Example 1 except that 1.5 g of N-isopropylmethacrylamide was added, and then the concentration of E. coli was measured.

Comparative Example 1

An antimicrobial coating agent was prepared in the same manner as in Example 1 except that the silver colloid powder was not added, and then the concentration of E. coli was measured.

Table 1 shows the antimicrobial test measurement results for the antimicrobial coatings prepared by the method according to Examples 1 to 3 and Comparative Example 1.

[Table 1]

Referring to Table 1, in the case of Examples 1 to 3, it can be seen that the concentration after 24 hours from the initial concentration: 1.6 × 10 ⁴ was sharply lowered to 110 CFU / ml or less. In particular, in the case of Example 3 to which N-isopropylmethacrylamide was further added, it confirmed that the antibacterial effect was the most excellent.

On the other hand, in the case of Comparative Example 1 without the addition of silver colloid powder, the concentration after 24 hours from the initial concentration: 1.6 × 10 ⁴ was lowered to 517 CFU / ml, but it is a significantly higher value than Examples 1 to 3 It can be seen that.
