The present invention discloses a device for internal drug injection of scars using carbon dioxide fractional laser scar removal, comprising a negative pressure pumping cylinder, a drug tap, and a scar patch. The negative pressure pumping cylinder comprises a cylinder body, a partition tube, an inner pumping rod, an inner piston, an outer pumping rod, an outer piston, and a handle. The drug tap comprises a tap body and a needle, the needle being fixed to the tap body vertically and extending therethrough. The tap body is provided with a vent. The tap body can be detachably fixed below the pressure pumping cylinder. The scar patch comprises a patch connecting portion, a pressing sealing membrane, and a scar enclosing cavity. The scar enclosing cavity is provided vertically and extending therethrough in the middle of the scar patch. The upper end of the middle portion of the scar patch can be detachably fixed below the pressure pumping cylinder, so that the push injection one-way valve and the negative pressure one-way valve are simultaneously connected to the scar enclosing cavity. The scar patch is fixed with a pressing sealing membrane on its lower surface, and the pressing sealing membrane can be hermetically attached to the skin. The present invention has the advantage of enabling drug solution to more easily enter the scar wound.

The invention provides application of a grease composition containing safflower seed oil and fermented artemisia apiacea 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 and the fermented artemisia apiacea oil in preparation of an external skin preparation with a post-medical repair effect.

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 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.
