The present application relates to the technical field of medical wound dressing, and provides a photothermal responsive Janus fiber dressing as well as a preparation method and application thereof.The Janus fiber dressing is prepared by compounding polycaprolactone / gelatin / curcumin nanofiber and polydopamine modified cotton gauze.The dressing has photothermal responsiveness and gradient structure, and can realize active exudate drainage / evaporation and synergistic sterilization under near-infrared light irradiation.Meanwhile, local photothermal can trigger on-demand release of curcumin in the PGC layer, play an anti-inflammatory effect, and at the same time, as a colorimetric pH sensor, realize real-time monitoring of the wound in situ.In an infected diabetic mouse model, the dressing exhibits a wound healing effect superior to that of a commercial cotton dressing by reducing inflammation, inhibiting bacterial colonization, promoting collagen deposition and angiogenesis.The Janus fiber dressing integrates exudate management-treatment-monitoring, and provides a new strategy for diabetic wound care.

The utility model discloses a kind of cotton gauze production drying machine, it includes: servo motor, the outer surface of the servo motor is fixedly connected with smooth wear block one, the inner surface of the smooth wear block one is slidably connected with rack, the outer surface of the other end of the rack is slidably connected with smooth wear block two, the outer surface of the smooth wear block two is fixedly connected with motor assembly one;The output end of the servo motor is fixedly connected with controllable temperature heater, the both end side surface of the controllable temperature heater is fixedly connected with arc heat-collecting plate one, the outer surface of the motor assembly one is fixedly connected with protective cover;Through the cooperation of above components, realize device heating end flexible movement and angle conversion, it is convenient for product to be heated more evenly, simultaneously also even conduction is carried out to the heat generated, avoid product local heating, additionally still recycle excess heat effectively save energy.

The utility model discloses a three -month paste with slow -release function belongs to the plaster of traditional chinese medicine technical field, three -month paste with slow -release function still includes the glue layer 12 of fixed connection on the upper end of cotton gauze layer 11, the inside of glue layer 12 is inlayed a pair of heat dissipation silica gel 13, two heat dissipation silica gel 13 and cover -like slow -release membrane 17 between inlayed snap ring 14, the outer circumference of snap ring 14 is fixedly connected with glue layer 12, and the lower end of two heat dissipation silica gel 13 is embedded in the inside of cotton gauze layer 11, through setting heat dissipation silica gel 13, further clamping hold snap ring 14, can conduct heat to outside while assisting clamping plaster 15, can be embedded glue layer 12 and cotton gauze layer 11 simultaneously, the connection of stable glue layer 12 and cotton gauze layer 11 prevents misplacement, improves the stability of three -month paste while increasing the cooling function, is more favorable to the absorption of slow -release medicine.

The utility model discloses a gauze raw material cleaning structure for medical gauze sheet processing belongs to medical health material preparation technical field, and its technical scheme main points include degreasing bin, the inside swing joint of degreasing bin has microwave directional catalysis mechanism, the inside swing joint of degreasing bin has annular spray catalysis mechanism, can realize pure cotton gauze continuous degreasing treatment through transmission roll, solved the traditional batch type operation process intermittent, time -consuming long problem, matches the industrialization continuous production demand, and utilize microwave generator through loudspeaker antenna directional transmission energy, the arc reflection board of combination rotatable adjustment makes microwave even distribution, can realize gauze from inside to outside heating, avoid " the problem of the dielectric loss of external heat internal cold", improve the grease decomposition efficiency, reduce the energy consumption, and need not long -time soaking sodium hydroxide stock solution, eliminate gauze stacking contact blind area and the penetration difference problem caused by the uneven thickness, promote and nanometer catalyst reaction decomposition.
