  • Patent number: 12173156
    Abstract: The present disclosure relates to a medical silicon rubber having high mechanical property and a preparation method thereof. The medical silicon rubber comprises the following raw materials in parts by weight: 50˜90 parts of silicon rubber, 10˜50 parts of polyurethane, 10˜50 parts of fillers, 2˜6 parts of hydrogen-containing silicon oil and 2˜5 parts of a vulcanizing agent. The preparation method comprises: evenly mixing a part of fillers with silicon rubber in an internal mixer, and evenly mixing the other part of fillers with polyurethane in the internal mixer; and mixing the mixed polyurethane on an open type rubber refining machine, then successively adding hydrogen-containing silicon oil, the evenly mixed silicon rubber and the vulcanizing agent into the open type rubber refining machine many times by small portions, and finally vulcanizing the mixed rubber on a plate rubber vulcanizing machine for 5˜15 min at 150˜190° C.

  • Patent number: 12083231
    Abstract: The preparation method of a starch-based double-loaded functional nanoparticle includes: performing restrictive hydrolysis treatment on egg high-density lipoprotein using proteases to obtain the polypeptide; performing self-assembling on a mixed system containing the polypeptide and quercetin under the alkaline condition to form a micelle nanoparticle; performing covalent grafting reaction on a mixed system containing the micelle nanoparticle and anthocyanin under the alkaline condition to form a graft; and electrostatically compounding carboxymethyl dextrin with the graft to obtain the starch-based double-loaded functional nanoparticle. In the preparation method, raw materials derived from natural sources are used, and the self-assembled colloid nanoparticle with good properties can be obtained by adjusting the pH without any organic reagents.

  • Patent number: 11857693
    Abstract: The disclosure provides a medical sealant glue capable of promoting wound healing and a preparation method thereof. The medical sealant glue is formed by covalent cross-linking of two components after being physically mixed by a mixing tool, wherein the first component is a nucleophilic component, and the second component is an electrophilic component. The medical sealant glue has a gelation time of 1-10 s, a swelling ratio of 0-100%, a bursting strength of 100-250 mmHg, and a degradation time of 0.5-300 days. The nucleophilic component of the medical sealant glue contains exosome or hyaluronic acid and chitosan, and thus the medical sealant glue not only has the effect of promoting wound healing, but also has antibacterial and anti-infection effects.
