The present invention relates to the technical field of cosmetics, and in particular to a product containing flexible glucan. The product can be prepared by using a high-pressure micro-jet to treat a material containing glucan. In the product containing flexible glucan of the present invention, the flexible glucan has special intramolecular and intermolecular arrangements, achieves excellent wound-healing-promoting and anti-inflammatory effects, when added to a cosmetic, shows a prominent skin-repair-promoting effect, can effectively improve the effect after medical aesthetic procedures such as fractional laser, chemical peel, and microneedling, and can also promote the repair of sensitive skin. The preparation method for the product containing flexible glucan of the present invention allows for adjustment of the intramolecular and intermolecular arrangements of the glucan and enhances the stability of the product at room temperature while improving the flexibility of the product, so that a large amount of the product can be added to a cosmetic.

This invention relates to the field of medical device fault diagnosis technology and discloses a fault detection method for a carbon dioxide fractional laser therapy instrument. The method establishes reference driving parameters and reference electrical impedance characteristics during the calibration phase; during detection, it simultaneously acquires scanning coordinates, laser voltage and current, and real-time driving signals. The method first calculates the laser's dynamic impedance based on voltage and current. If the impedance deviates from the reference characteristics, the fault source is determined to be the laser. If the impedance is normal, a compensation intensity scalar is calculated based on the difference between the real-time driving signal and the reference parameters, and the emitted test pulse train is controlled to calculate the power modulation slope. Finally, based on the spatial distribution of the compensation intensity scalar with the scanning radius and the power modulation slope, the fault type is determined to be a geometric alignment fault, a thermal contamination fault, or a global optical path attenuation. This invention can effectively distinguish between electrical system faults and optical system faults and accurately identify the specific attributes of optical path faults.

The invention provides an application of a grease composition containing safflower seed oil, fermented artemisia apiacea oil and selaginella oil in post-medical repair. The fermented artemisia apiacea oil is prepared by the following steps: (a) carrying out supercritical CO2 extraction on artemisia apiacea medicinal materials; (b) fermenting, namely fermenting by adopting bifidus yeast; (c) separating to obtain fermented artemisia apiacea oil; wherein the bifidobacterium is selected from bifidobacterium adolescentis, bifidobacterium animalis subspecies, bifidobacterium animalis subspecies lactis, bifidobacterium bifidum, bifidobacterium breve, bifidobacterium longum subspecies longum or bifidobacterium longum subspecies infantis. The medical art is caused by dot matrix laser. The invention further relates to application of the grease composition containing the safflower seed oil, the fermented artemisia apiacea oil and the selaginella oil in preparation of an external skin preparation with a post-medical repair effect.

The invention discloses a dot matrix laser output method, device and equipment and a storage medium, and relates to the technical field of laser control, and the method comprises the steps: obtaining a movement track of a laser scanning device in a to-be-treated skin area in response to a signal for starting laser output; and according to the galvanometer angle array, outputting target dot matrix light spots in order to the to-be-treated skin area, wherein the galvanometer angle array is determined based on the movement track. Compared with existing stamping type dot matrix scanning, after the user inputs the laser output signal, the vibrating mirror angle array is generated by detecting the movement track of the laser scanning device operated by the user in the to-be-treated skin area, and then the target dot matrix light spots in the tidy array are automatically output to the to-be-treated skin area based on the vibrating mirror angle array. Therefore, comprehensive automatic dot matrix scanning of the to-be-treated skin area is achieved, dot matrix light spots in an array form are output, missing scanning and repeated scanning can be avoided, and dot matrix scanning efficiency and scanning precision are improved.
