Abstract: Disclosed is a method for preparing a product for treating scald infection caused by Pseudomonas aeruginosa. The product includes a ferrous sulfate hydrogel, the scald is a deep second-degree scald or a third-degree scald, and a preparation process of the ferrous sulfate hydrogel includes: S1, obtaining a mixed solution by dissolving ferrous sulfate and vitamin C at a concentration ratio of 1:1 in sterile ultrapure water, heating the mixed solution to 50° C., and a concentration of the ferrous sulfate in the mixed solution being 2 mM, and S2, under a condition of heating, continuing to add sodium alginate powder whose mass constitutes 3.5% of a total mass of the mixed solution, stirring until the sodium alginate powder is dissolved and forming a stable colloid, and obtaining 2 mM of the ferrous sulfate hydrogel.

Abstract: An application of a hydrogel in the preparation of products for the treatment of bacterial infection is disclosed. Ferrous ion was used in the antibacterial activity test of Staphylococcus aureus and showed a strong bactericidal effect, which the survival rate of Staphylococcus aureus is less than 0.001%, as well as the survival rate of methicillin-resistant Staphylococcus aureus (MRSA) was less than 0.01%. Ferrous ion hydrogel was used for the treatment of keratitis and skin wound infection. Ferrous ion hydrogel for the treatment of keratitis and skin wound infection, which can significantly reduce the risk of pulmonary MRSA infection, prevented the dissimilation of MRSA to the lung, and alleviated systemic inflammation in the body in a timely and effective manner, revealing the therapeutic potential of ferrous compounds for treatment of Staphylococcus aureus infections, including MRSA.

Abstract: A transmission-type OLED riflescope with a prism assembly having an ocular lens and an objective lens, wherein the prism assembly has a roof prism, a half pentaprism, an isosceles prism and a spectro-film, and the right end of a laser receiver abuts against the left end of the isosceles prism so that both of the laser receiver and the isosceles prism are located below the axis of the lens cone while the laser transmitter is located above the axis of the lens cone with the laser transmitted from the laser transmitter exiting after being refracted by the objective lens, while a transmission-type OLED display is arranged between the ocular lens and the prism assembly. Functions of the riflescope include observing, aiming, and laser ranging and transmission using the same objective lens. The viewer can also see the objects behind the lens.
