6 results about "Snail slime" patented technology

The invention relates to a method for producing a masonry composite (1) from masonry blocks (2) which are laid in layers one above the other, each separated by a bed joint (3), wherein a thin-bed adhesive is applied to contact surfaces of the masonry blocks (2) for bonding the layers in the bed joint (3), wherein snail slime or a substitute for snail slime is used as the thin-bed adhesive.

The invention belongs to the technical field of small molecule active peptides. The amino acid sequence of the active peptide SIRPDTK sourced from snail mucus is Ser-Ile-Arg-Pro-Asp-Thr-Lys, and the molecular weight of the active peptide SIRPDTK sourced from snail mucus is 816.152 Da. The invention is used for solving the technical problems of large molecular weight, low transdermal absorption rate, easiness in causing allergy and the like although the existing proteins such as EGF (epidermal growth factor) can promote repair. The invention also relates to a preparation method of the active peptide from snail mucus. The invention also relates to a synthesis method of the active peptide from snail mucus. The invention further relates to application of the active peptide from the snail mucus.

The invention discloses a high-quality snail mucus and an extraction method thereof, and the extraction method comprises the following steps: S1. Select healthy snails, place the snails in a clean place, and fast for 1-5 days; S2. After the fasting ends, feed the snails with feed, which is rich in polysaccharides and mucin; S3. Take out the snails that have been fed with feed for 1-5 days, disinfect and clean the surface, and use a mild bactericide for the cleaning liquid, and rinse with clean water after cleaning; S4. Knock open the snail shell, remove the snail shell and impurities, take out the snail meat and put it in a clean container; S5. Add the extract, stir evenly, let it stand, let the snail secrete more liquid, and filter out the snail secretion liquid. The snail mucus extracted by the extraction method of the present invention is of high quality and can maintain viscosity for a long time without being made into dry powder.

The present invention discloses a dual-airway bionic snail soft robot, which includes ventral muscular feet, an air pressure controlling device and mucus, wherein the ventral muscular foot includes an upper deformation layer, a lower deformation layer and a strain sensor. Snail ventral muscular feet are simulated by the upper deformation layer and the lower deformation layer to produce wave motion. The strain sensor senses a wave motion state of the soft robot to provide a basis for the air pressure controlling device to output air pressure. In another aspect, snail mucus is replaced with glycerin to produce a suction force and improve crawling efficiency. The designed bionic snail soft robot can move forward, move backward and turn in situ, thereby realizing free movement in a microgravity environment.

The invention belongs to the field of snail mucus extraction, and provides snail mucus extraction equipment and method.The snail mucus extraction equipment comprises a control base, a mucus extraction cabin is installed on the top face of the control base, a mucus collection cabin is installed on the outer side of the mucus extraction cabin, and a mucus scraping mechanism is installed in the middle of the mucus extraction cabin; the mucus scraping mechanism is located between the mucus extraction cabin and the mucus collection cabin and is provided with a snail ventilation assembly; a motor slowly rotates to drive a second arc-shaped scraping plate to rotate on the inner wall face of the hemispherical hatch cover, snails crawling on the inner wall face of the hemispherical hatch cover are scraped, the snails fall into the extraction groove again, snail mucus attached to the inner wall face of the hemispherical hatch cover is scraped through the second arc-shaped scraping plate, and therefore the snail extraction efficiency is improved. The snails can conveniently climb on the inner wall face of the hemispherical hatch cover for the second time to secrete mucus and timely collect the mucus, and the mucus is prevented from losing activity.

This invention discloses a quaternized pullulan / cellulose composite hemostatic sponge containing snail mucus, its preparation method, and its application, belonging to the field of biomedical materials technology. The quaternized pullulan / cellulose composite hemostatic sponge containing snail mucus is obtained by cross-linking hydroxypropyl methylcellulose, quaternized pullulan polysaccharide, and snail mucus powder with a cross-linking agent; the mass ratio of hydroxypropyl methylcellulose, quaternized pullulan polysaccharide, and snail mucus is 1.9-2.1:1:3.8-4.2. The quaternized pullulan / cellulose composite hemostatic sponge containing snail mucus of this invention can solve the problems of insufficient porosity, poor wet tissue adhesion, single hemostatic mechanism, and low functional integration of existing hemostatic materials.
