Dye for preparing brown catgut suture

Abstract

The invention discloses a dye for preparing a brown catgut suture, and belongs to the field of biological sutures. The dye is prepared from dichromate, pyrogallic acid, sodium hydrogen sulfite and traditional Chinese medicine water extract, wherein the traditional Chinese medicine water extract is a water extract of moutan bark, radices trichosanthis, cinnamomum cassia, lignum dalbergiae odoriferae, scutellaria indica, folium artemisiae argyi, ludwigia hyssopifolia, calcined oyster shell, tung flower, radix angelicae, lotus leaves, cortex dictamni, herba violae, polygala tenuifolia, raspberry, rhodiola rosea, rheum officinale, azedarach, flos hibisci, clerodendrum japonicum leaves, radix dryopteris filix-mas and aralia cordata. In the dye, a coloring component is prepared from the dichromate, the pyrogallic acid and the sodium hydrogen sulfite; bleached catgut can be immersed into the dye and can be quickly dyed to be brown, and the brown catgut suture is safe and unfading. According to the dye disclosed by the invention, traditional Chinese medicine liquid is added in the dye, and the traditional Chinese medicine components can be adsorbed onto the catgut suture after the catgut suture is immersed in the traditional Chinese medicine liquid; the brown catgut suture which is prepared by using the dye is capable of promoting the healing speed at a suture position and has an antibacterial effect.

Description

Technical field [0001] The invention relates to the field of biological sutures, in particular to a dye for preparing brown sheep intestine sutures. Background technique [0002] At present, some sutures used for postoperative suture use silk threads that cannot be absorbed by the human body. It will cause undesirable consequences such as easy inflammation after surgery. The application of sheep intestine sutures makes up for the above shortcomings. The sheep intestine sutures can be slowly absorbed by the human body and merge into one. [0003] The Chinese invention patent with publication number "CN1363397A" discloses "a manufacturing process of goat intestine medical biological suture", the second page of the manual, the second line of Example 2 "Bleaches with 0.1% hydrogen peroxide at room temperature for 5 hours , Put the casing in 0.3‰ of chromium solution, while adding acetate to fix the chromium", the said chromium solution is used to dye the sheep's gut brown.
