The preparation method of adjuvant is:
Soybean lecithin is added to the water 50-60 DEG C, 800-1000r/min stirs 1-2h, add glycerol, Polyethylene Glycol, Pseudobulbus Bletillae (Rhizoma Bletillae) superfine powder and mannitol similarity condition again and stir 10-15min, add all the other raw materials 400-600r/min after cooling and stir 5-10min, to obtain final product.
A preparation method for HP-β-CD hemostatic gauze, is characterized in that, comprises the following steps:
(1) by solvent and solute weight ratio 10:1-8:1 Folium Luffae, Cacumen Platycladi, Sanguis Draxonis, Herba Duchesneae Indicae and Pollen Pini added in the acetum of 4-8% and decoct 4-8h, filter, be concentrated into the 1/10-1/8 of original volume after pH being adjusted to neutrality, obtain concentrated solution; Described concentrated solution and gelatin, HP-β-CD and Tween-80 are added jointly in the water that 1/3-1/2 measures, prior to 60-80 DEG C, 400-600r/min stirs 0.5-1h, stir 1-2h under adding decanoyl/octanoyl glycerides and adjuvant 40-50 DEG C, equally rotating speed again, after cooling, obtain component A;
(2) add in the water of surplus by sodium alginate and sodium carboxymethyl cellulose, 800-1000r/min stirs 0.5-1h, obtains B component;
(3) filter after component A and B component mix homogeneously and vacuum defoamation, obtain spinning solution; Spinning solution is added in wet-spinning frame under room temperature, separated out in coagulating bath after extruding by dosing pump metering, spinning head and form composite fibre long filament, described coagulating bath is the mixed solution containing 1-2% citric acid (mass ratio) and 60-70% ethanol (volume ratio), coagulation bath temperature is 20-40 DEG C, and spinning speed is 2-5m/min;
(4) make gauze by after the composite fibre long filament drying obtained in (3), through cutting out, sterilizing and packaging process, get product.
Folium Luffae is cucurbitaceous plant Fructus Luffae or Guangdong Fructus Luffae blade, and primary efficacy has hemostasis, heat-clearing and toxic substances removing, preventing phlegm from forming and stopping coughing; Sanguis Draxonis medical material Ji Yuan takes from the resin in babassu Sanguis Draxonis fruit and rattan, has effect of removing blood stasis and relieving pain, hemostasia and promoting granulation, also has the pharmacological action of bactericidal antiphlogistic.
Advantage of the present invention is:
The present invention obtains soluble stanching gauze by natural macromolecular material synergism synthesis composite fibres such as HP-β-CD, gelatin, sodium alginate, sodium carboxymethyl cellulose, anthemorrhagic speed is fast, effective promotion wound healing, good anti-bacterial effect, be easily absorbed by the body, good biocompatibility, has no side effect; By extracting and composite active ingredient of natural plant, energy broad-spectrum antiseptic, anti-inflammatory analgesic, and there is slow releasing function, effectively extend action time, reach better result of use.
