Abstract
A process for preparing high-molecular medical material includes such steps as washing fresh living silkworms just spinning out silk with distilled water at 20-30 deg.C, cutting open the silkworms in sterile vacuum room to expose two silk glands, cutting off the said silk glands, sucking in the silk glands, filter and loading in sealed container. It has no toxic by-effect.
Description
The invention belongs to the preparation method of a kind of preparation methods, particularly a kind of natural medical polymer materials.
The material that existing medical apparatus is used such as the overwhelming majority such as disposable syringe, catheter adopt chemical process synthetic macromolecular material, and this material is toxic side effects all more or less, and the patient is impacted.
The preparation method who the purpose of this invention is to provide a kind of natural medical polymer materials without any side effects is to satisfy the needs of human health.
Technical solution of the present invention is: a kind of preparation method of natural medical polymer materials comprises the steps:
A, with 20～30 ℃ distilled water with fresh and alive put on an arrow just weaved silk five age the silkworm worm clean up;
B, sterile vacuum indoor with described five age the silkworm worm cut open, expose two bar meander-like silk glands;
C, the two ends of silk glands are cut off;
D, the inlet of suction apparatus is aimed at described silk glands, and silk glands is sucked in this device;
E, again silk glands is filtered, wash silkworm endosome brin element, remove incidental foreign material when drawing;
F, the container inner sealing of packing into are preserved.
Described sterile vacuum chamber can be the tank that fills distilled water.
Described suction apparatus can be injector for medical purpose.
The present invention compared with prior art because this material is not to utilize the chemical process synthetic, belongs to the pure natural material, therefore has advantage without any side effects.
Below in conjunction with embodiment the present invention is further described:
Put on an arrow just weaved silk five age the silkworm worm be in and desire the state of weaving silk because the silkworm worm is after death, its intravital silk glands is that fibroin can digest, therefore must get fresh and alive put on an arrow just weaved silk five age the silkworm worm, the silkworm worm cleaned up and sterilize with distilled water.The tank of making of stainless steel plate fills mobile distilled water, and its temperature is 20～30 ℃, is equivalent to " inferior vacuum " in the distilled water.Both hands are immersed in the distilled water silkworm worm are cut open, make it expose silk glands and get final product.Cut off the two ends of silk glands, the injector for medical purpose port that will remove syringe needle is aimed at silk glands and with its suction.Reinject in the uncovered cup of filter screen, and in the mobile stainless steel distillation tank with 45 ℃～55 ℃ of cup immigrations, wash silkworm endosome brin element, remove the incidental useless foreign material of possibility when drawing, draw with another syringe that removes syringe needle again, afterwards, discharge big portion moisture content, assemble and be collagen shape, promptly salable being kept in the refrigerator.Above process is all carried out in distilled water, to guarantee not ingress of air of fibroin.Also can adopt industrialized production to carry out, promptly between the vacuum cart of conditions such as high pressure, aseptic thermophilic, carry out.
Use is: imitative blowing material control formula can be made tubulose with this product, or imitative rolling formula or blow molding type make all formulas of film, can be respectively as medical catheter or medical film etc.This product directly can also be coated on the organ that needs adventitia,, form outer as heart pacemaker appearance.
