Abstract
The invention provides a production method of a surgical dressing by irradiation sterilization, and relates to the technical field of production of surgical dressings. The production method is characterized in that natural-occurring substance powder with the functions of fighting bacteria, diminishing inflammation, reducing scars, promoting wound healing and relieving pain is mixed with vaseline to obtain composite vaseline, the vaseline is combined with a medical gauze, and then the processed medical gauze is sterilized in an irradiation manner, thus the surgical dressing by irradiation sterilization has outstanding coverage, and can prevent a wound from mechanical injury, polluting and chemical stimulation, resist dry, moisture and secondary infection, reduce the loss of electrolyte and energy, actively promote the wound healing, and change the micro-environmental impact; in addition, the surgical dressing cannot be adhered with the wound, so that the wound healing is promoted, and no second damage is brought to the wound during dressing change.
Description
Technical field
The present invention relates to the production technical field of medical dressing.
Background technology
People's skin is made up of three layers of epidermis, corium and subcutaneous tissue, has the invasion of the outer pathogenetic bacteria of opposed body, and excretion human body waste prevents that body moisture evaporation scatters and disappears, and mediator's temperature is experienced the critical function such as stimulation of pressure, temperature, chemicals.Because of wound, gunshot wound, when burn and festering etc. causes skin damage, be easy to germ contamination, moisture content runs off, there is inflammation, the complication such as pain, when treatment, need to protect wound surface and wound healing with medical dressing, the absorbent cotton that traditional medical dressing is conventional or cotton gauze processed, the medical dressing that viscose rayon etc. are processed into, in use, directly be applied on wound, by pressing the effect of playing hemostasis and covering wound, but wound is in the time of healing, often there will be dressing and wound to stick together, unsuitable wound healing, while changing dressings, can bring secondary to destroy to wound, bring misery to patient, trauma wounds feature Intradermal tissue exposes, easily infect, wound also has a large amount of blood or effluent.
Summary of the invention
The medical dressing production method of the function irradiation sterilizations such as the object of the invention is to provide a kind of and has good spreadability, prevent germ contamination, have antibacterial, pain relieving simultaneously, wound healing promoting.
The compound vaseline of the present invention's dip-coating on hospital gauze, cold wind dry up, press from both sides film compound, cut into slices, pack and irradiation, described compound vaseline is by vaseline and have natural materials powder antibacterial, that diminish inflammation, reduce cicatrix, wound healing promoting, pain-relieving functions and form.
The present invention will have antibacterial, diminish inflammation, reduce cicatrix, wound healing promoting, natural materials powder and the vaseline of pain-relieving functions are mixed to form compound vaseline, through being combined with hospital gauze, again through irradiation sterilization, there is excellent spreadability, also tool is resisted wound and damaged by mechanical factor, pollute and chemical stimulation, anti-drying, moist, two degree infect, reduce electrolyte and loss of power, initiatively affect wound healing, microenvironment impact etc., and there will not be dressing and wound to stick together, improve the healing effect of wound, while changing dressings, more can not bring secondary to destroy to wound.
In addition, the present invention is under 35～50 DEG C of temperature environments, in the agitator of 1000～5000r/min, by vaseline with have a natural materials superfine powder mix homogeneously antibacterial, that diminish inflammation, reduce cicatrix, wound healing promoting, pain-relieving functions.
The mixing temperature of selecting and rotating speed can guarantee that natural materials superfine powder fully mixs homogeneously with vaseline.
Described have powder antibacterial, that diminish inflammation, reduce cicatrix, wound healing promoting, pain-relieving functions can be in tea polyphenols, Cordyceps militaris (L.) Link., chitin, chitosan or chitosan at least any one.
Described hospital gauze is bamboo fibre gauze or chitosan gauze etc.
Hospital gauze was soaked in the compound vaseline of 40～60 DEG C, control hospital gauze containing compound vaseline amount by selected dipping temperature, the speed of soaking, and determined through clinical test of many times, the hospital gauze soaking is containing compound vaseline amount 180～280g/m
2for the best.
Antibacterial in order to ensure having, to diminish inflammation, reduce cicatrix, wound healing promoting, pain-relieving functions natural materials powder is in the distribution of hospital gauze and wound contact surface, the rapid condensation of compound vaseline on hospital gauze on streamline, described cold wind dries up, and cold wind temperature is-10～-30 DEG C.
In addition, in order to save the consumptions such as expensive chitin or chitosan, dry up simultaneously at cold wind, evenly spray the natural materials such as chitin or chitosan powder to hospital gauze and wound contact surface.Can make that effective ingredient concentrates on gauze with wound contact surface one side, be also beneficial to raising drug effect.
Described folder film is compound is the compound PE film that can open before use on hospital gauze and wound contact surface, in the another side composite water absorbing dressing of hospital gauze.
Described water suction dressing is calcium alginate fibre or carboxymethyl-modification cotton cloth etc.
Described irradiation is before and after adopting automatically to hospital gauze after packing, stand up piling suspension chain up and down carries out continuous irradiation, position, source coding is designated as 13855 ± 10, suspended chain speed electrical quantity is 15～25Hz, is 1.2～1.5 with batch product box unevenness, irradiation dose is 15～26KGY, guarantees that irradiation affects and in little situation, reaches again sterilization effect natural materials superfine powder effect.
The present invention's remarkable advantage compared with existing medical dressing is: 1, the present invention selects bamboo fibre, chitosan gauze, itself has fine air permeability, water absorption, has again natural antibacterial, a biocidal property.2, compound vaseline coordinates and covers wound surface with calcium alginate fibre or carboxymethyl-modification cotton cloth, because internal layer vaseline has water proofing property, is difficult for and water mixing, can prevent gauze and wound surface adhesion, and the lubricated sticky wound of tool, promotes granulation growth; Outer floor height water suction dressing can absorb again the effluent oozing out, and can keep well the certain humidity of wound surface and the favourable wound healing of microenvironment.3, select containing pain relieving, hemostasis, promotion wound healing, reduce the natural materials micropowders such as cicatrix, antibacterial tea polyphenols, Cordyceps militaris (L.) Link., chitin, chitosan, chitosan, take respectively to mix with vaseline, dust when air-cooled, be conducive to according to each natural materials physicochemical property, reasonable price utilization the more economical large effect of performance tool.4, adopt reasonable irradiation technique, can ensure that medical dressing is aseptic, guarantee again effect of natural materials.5, in technique, adopting hospital gauze to be coated with compound vaseline is the method for soaking fast, can be by temperature, soaked speed controlling gauze oil content, and favourable industrial scale is produced again.
