Abstract
The present invention relates to a new process for producing an absorption styptic sponge used for operation by animal hide. The present invention mainly comprises the following procedures: 1. animal hide slag is soaked by Ca (OH) 2 water solution; 2. expanded hide material is washed by water with the ph value of 6.5 to 8 and then is soaked by mixed solution of HCl and H2SO4; 3. the soaking solution is neutralized until pH value is equal to 6.5, and is agitated to make into neutral hide material; 4. the neutral hide material is washed by water and then is pickled to form colloidal hide material; 5. the soaking solution is neutralized and agitated; 6. water is added for cooking the colloidal hide material to obtain dilute gelatin solution; 7. the dilute gelatin solution is sucked in a vacuum and is filtered to obtain pure dilute gelatin solution; 8. the gelatin solution is concentrated in a vacuum; 9. the concentrated gelatin is foamed under a vacuum condition; 10. the foamed gelatin solution is blown into a sponge shape by high-pressure cold air; 11. the gelatin sponge is dried by infrared rays of 120 to 150 DEG C for forming.
Description
One, technical field
The present invention relates to make the process of sthptic sponge, particularly a kind of new technology with animal leather skin production operation absorption styptic sponge.
Two, background technology
At present, being used for the hemostatic sponge in the operation process is gelfoam, and this sponge in fact is to be with foraminous gelatin, general becomes block, selects sizable one to fill in wound and stop blooding during use.Because the size and the shape of gelatin sponge blocks often do not conform to wound, so use very inconvenient.
Three, summary of the invention
The present invention will provide a kind of new technology with animal leather skin production operation absorption styptic sponge.
The production technology of operation absorption styptic sponge, concrete technological process is:
Operation 1, the Ca with 4～10% (OH)
2Aqueous solution soaks cleaned animal leather skin slag 70～90 days, makes expansible skin material;
Operation 2 after the water flushing of expansible skin material with ph=6.5-8, is [H with molar concentration once more
+]=0.45 (± 1) mol/l's, press 4-6: the blended HCl of 6-4 proportioning, H
2SO
4Solution soaking further expands the leather hide fiber to the pigment that can rub with the hands on the shedding material, is convenient to thoroughly remove oxious component;
Operation 3 adds NaOH in the soak of operation 2, it is 6.5 that soak is neutralized to pH value, then uses the skin material in the mechanical agitation fermentation vat, and mixing time is no less than 4 days, makes neutral skin material;
Operation 4, after neutral skin material water cleaning, being dipped in concentration is that soak time is no less than 5 days in the HCl aqueous solution of 5.5-6.5%, with clear water the HCl aqueous solution being diluted to pH value again is 5, and the fiber in the skin material is expanded more, forms the colloidal skin material;
Operation 5 adds NaOH in the soaking solution of operation 4, being neutralized to pH value is 6.5, the reuse mechanical agitation, and add the washing be no less than 3 days, then pull the colloidal skin material out;
Operation 6 adds clear water with the colloidal skin material, with 60～85 ℃ of steaming and decoctings, is brewed into concentration and is rare gelatin solution of 1～2%;
Operation 7, rare gelatin solution that last process is made filters by the kieselguhr vacuum filter earlier, with thorough filtering pigment impurity and remaining fiber, makes pure rare gelatin solution;
Operation 8 concentrates through vacuum decker with pure rare gelatin solution, produces gelatin solution;
Operation 9 is got blisters dense gelatin under vacuum condition;
Operation 10 becomes spongy with the gelatin solution after getting blisters with-28 ℃ to-20 ℃ cold high pressure wind;
Operation 11 will place on 120～150 ℃ the infrared drying bed re-pasteurization, drying and moulding through the gel sponge that last process was handled.
In above-mentioned process, handle by operation 1 to operation 5, oxious component is removed gradually, and the leather hide fiber fully can be reduced into collagen protein, if the fresh clean skin of employing this can omit this several procedures.
