Description
Technical field
The present invention relates to the manufacture method of a kind of bioactivity charcoal, use activated carbon make preparation as oxy-gen carriers or apply
Material etc., belong to the industry fields such as medical cosmetology, medicine and cosmetics.
Background technology
The prolonged of wound is the most one of Now Domestic technical barrier that surgery faces outward, also brings huge to traumatic patient
Painful.One little minor cut or wound, the most always cannot heal, not even time have a dull ache.Data shows, China's Surgical Inpatients
In, because skin chronic injury or the ulcer of refractory need the patient of hospitalization to account for 1.5%, wherein diabetic ulcer accounts for
36%, and than adding 6 times before 10 years.
Scientist is early it was demonstrated that the healing of epidermal wound needs certain oxygen.Micro-oxygen technology refers to use trace to provide
The technology of oxygen, is currently used primarily in the needs improving the aspects such as industrial food production, sewage disposal, therapeutic treatment.At present, state
Inside and outside used micro-oxygen technology, the wounds such as Bone Injury, diabetes chronic ulcer wound surface, surgical operation wound surface are taked oxygen therapy
Method, every day to wound for oxygen blast gas 2 times, each 30 minutes, in order to promote wound healing.Oxygen therapy device is divided into two kinds, a kind of
It is made up of oxygen caisson, oxygen catheter and oxygen mask, is controlled by oxygen oxygen valve during use, slightly pure for blowing to wound
Oxygen；Another kind of oxygen therapy device is Oxygen therapy apparatus, is made up of oxygen generating plant and pipe fitting, switches on power during use, and oxygen instrument processed produces oxygen,
To wound for oxygen blast gas, in order to improve damage tissue oxygen Gas content, prevent inflammation from occurring, promote wound healing.
But, in the market the oxygen therapy promoting wound healing effect is had a disadvantage in that
1) oxygen therapy device equipment volume is big, and assembly is miscellaneous many, operates with inconvenience, and patient compliance is poor；
2) some oxygen therapy equipment needs power supply, cannot use in the case of power free；
3) short to wound oxygen supply time.Wound is treated by general oxygen, and method is every day 2 times, one time 30 minutes.
The extended treatment time, patient does not complys with so that oxygen therapy can not play greatest treatment efficacy；
4) anaerobe is played certain inhibitory action by prior art oxygen therapy, but on aerobe without impact；
5) carry inconvenience, be not suitable for going out, travelling and the standby use of family presiding judge.
The present invention, through lot of experiments, uses activated carbon as oxy-gen carriers, utilizes the surface area that activated carbon is huge
With complicated pore structure feature and powerful absorbability, by Oxygen Adsorption in activated carbon hole, reapply hydrophilic high
Oxygen is locked in activated carbon by molecular material (such as acrylic amide, alginic acid salt, gelatin class etc.), makes bioactivity charcoal.Carry
Oxygen activity charcoal has extensive industrial use and medical application, in medical product, can join gel, ointment, spray
Etc. in dosage form, make wound wet dressing (such as wound repair gel, repairing dressing etc.)；Bioactivity charcoal may also pass through drying,
Make powdery, add on adhesive-bonded fabric dressing, make wound dry dressing (such as adhesive bandage, burn patch, trauma plaster etc.)；As made up
Product add bioactivity charcoal, epidermal cell proliferation can be promoted, repair skin damage barrier, adsorb antibacterial, prevent antibacterial from infecting,
Reduce inflammation to occur.Can be additionally used in and improve hair microenvironment, adsorb antibacterial, reduce dandruff and occur.
When traumatism treatment, the preparation being made up of bioactivity charcoal or dressing, wound can be directly applied to or spread on wound table
Face, lentamente releasing oxygen, promote wound healing.Meanwhile, activated carbon releasing oxygen simultaneously be also equipped with adsorb antibacterial, antibacterial carefully
Bacteria growing, prevents wound infection, accelerates the effects such as wound healing.Therefore, the present invention has intended to solve that current wound oxygen therapy is deposited
Shortcoming, and have the advantage that feature:
1) use bioactivity charcoal preparation to Wound healing and bone regeneration, only need to be applied in wound affected part, easy to use；
2) without power supply when bioactivity charcoal preparation uses, can carry at any time, be suitable at home, travel and medical institutions doctor
Use；
3) bioactivity charcoal preparation is coated on wound patient, can the most stably discharge micro-oxygen.Can be wound for a long time
Micro-oxygen environment, accelerating wound healing are provided, reduce scar hyperplasia；
4) bioactivity charcoal maintains the adsorption of activated carbon, adsorbable bacterial wound, prevents wound infection from suppurating, and inhales
Receive tissue exudates, promote wound healing.
Summary of the invention
The key technology of the present invention is as carrier with porous material (activated carbon, kieselguhr etc.), and adsorption of oxygen utilizes height
Oxygen is locked in the oxygen carrier system formed in carrier, sustainable release trace oxygen by the film property of molecular material.
The present invention selects activated carbon as oxy-gen carriers, utilizes surface area and complicated pore structure spy that activated carbon is huge
Point and powerful absorbability, by Oxygen Adsorption in activated carbon hole；Reapply hydrophilic high molecular material to be locked in by oxygen
In activated carbon, make bioactivity charcoal.Hydrophilic high molecular material aqueous solution has dissolved oxygen function, and concentration of oxygen gas is at height
Molecular material aqueous solution is formed the most steadily, the energy slowly sub-molecule of sustained release micro amount of oxygen, improves local microenvironment oxygen and contains
Amount.
The manufacture method of bioactivity charcoal of the present invention is specific as follows:
1) add the powdered activated carbon less than tank body volume 2/3 to vacuum response tank, build lid；
2) by evacuation in vacuum response tank, and vacuum is less than-0.1kg/cm2；
3) in vacuum response tank, purity oxygen is inculcated, until pressure inside the tank is less than closing oxygen valve during atmospheric pressure；
4) in vacuum response tank, 0.01%-5% (W/W) hydrophilic high molecular material aqueous solution, hydrophilic high score are added
Sub-aqueous solution is 2: 1 with activated carbon weight ratio, adds while stirring；After stirring 2 hours, regulation pH value is to 7.0 ± 0.5, is stirred for 1
Hour make mix homogeneously.
5) unload and be loaded in bucket to obtain moist bioactivity charcoal.Moist bioactivity charcoal can be added directly into liquid, semisolid
Solution is made corresponding spray or liniment, gel or ointment, for medical science, cosmetic use.
6) moist activated carbon is after 45 degree dry, and is again ground into powder, obtains dryness bioactivity charcoal.
Dryness bioactivity charcoal adds in liquid or semisolid, can be made into the health cares such as liniment, spray, gel
Product.Also medical application, non-woven fabrics, woven cloths can be made, for health and medical service with the blending such as Plant fiber, chemical fibre.
Heretofore described hydrophilic high molecular material includes acrylic amide, alginic acid salt, gelatin class moulding property high score
Sub-material, the most any is gelatinous macromolecular material for pinning the aqueous solution of oxygen in activated carbon space.
The present invention solves the shortcoming existing for current wound oxygen therapy, and has the advantage that feature:
1) use bioactivity charcoal preparation to Wound healing and bone regeneration, only need to be applied in wound affected part, easy to use；
2) without power supply when bioactivity charcoal preparation uses, can carry at any time, be suitable at home, travel and medical institutions doctor
Use；
3) bioactivity charcoal preparation is coated on wound patient, can the most stably discharge micro-oxygen.Can be wound for a long time
Micro-oxygen environment, accelerating wound healing are provided, reduce scar hyperplasia；
4) bioactivity charcoal maintains the adsorption of activated carbon, adsorbable bacterial wound, prevents wound infection from suppurating, and inhales
Receive tissue exudates, promote wound healing.
