The invention discloses a limb fixing device for a critical patient, belongs to the technical field of limb fixing, and aims to solve the problems that the contact area between a bandage and the arm of the patient is small, the constraining force is concentrated, pressure injury is easily formed due to long-time constraining, the pain of the patient is increased, local infection is possibly caused, and the illness state is aggravated. The hospital bed comprises a hospital bed body and two supporting plates fixed to one side of the hospital bed body, restraint straps are arranged on one sides of the supporting plates, a plurality of first pressure air bags are installed on one sides of the restraint straps, a plurality of second pressure air bags are further installed on one sides of the restraint straps, and the second pressure air bags and the first pressure air bags are arranged in a staggered mode. Alternate inflation and deflation of the first pressure air bag and the second pressure air bag are achieved through the two-way air pump, so that the pressed parts of the limbs are continuously alternated, local skin and soft tissue are prevented from being in a pressed state for a long time, local blood circulation is effectively improved, the problems of skin redness, pressure sores, limb ischemia and the like are solved, and the completeness of the limb tissue of a patient is protected.

This invention discloses a nutritional composition and preparation method for improving joint health in senior pets. The nutritional composition comprises: N-acetylglucosamine, chondroitin sulfate, methanesulfonylmethane, unsaponifiable avocado and soybean extract, hyaluronic acid, curcumin microcapsule powder, and high-concentration fish oil. This invention uses a lipid / polysaccharide bilayer microcapsule structure to encapsulate curcumin and fish oil, and prepares the product through low-temperature homogenization, spray drying, and granulation processes. The composition of this invention works synergistically through multiple pathways, simultaneously exerting effects on three key levels: anti-inflammation, lubrication, and cartilage repair. It can significantly inhibit joint inflammation, improve joint lubrication, and promote cartilage repair. This invention solves the problems of existing pet joint products, such as single pathways of action, low stability and bioavailability of lipid-soluble active ingredients, and lack of overall formulation optimization tailored to the characteristics of aging pets. It is suitable for daily joint health maintenance or adjunctive treatment in middle-aged and senior dogs and cats.

This invention discloses a polyacid-based mild acne-removing composition, its preparation method, and its application, belonging to the field of acne treatment preparation technology. By mass percentage, the polyacid-based mild acne-removing composition comprises 1%–10% bee venom peptide, 0.25%–5% microcapsules containing polydeoxyribonucleotides, 0.2%–1.5% soothing active ingredients, 0.5%–3% biosaccharide gum-1, 0.2%–2% biosaccharide gum-2, 0.05%–0.5% astragalus gum, 0.1%–1% pH buffering compound, 2%–10% acid mixture, and 3%–20% alcohol mixture, with the balance being water. This acne-removing composition achieved a low-irritation user experience with a high-concentration polyacid formula in subjects with sensitive, mild to moderate facial acne, effectively improving the problems of poor tolerance and limited applicability of traditional acid-based acne products for sensitive skin, significantly broadening the applicable skin types and application scenarios for high-efficacy acid-based acne products, and balancing effective acne removal with safety suitable for sensitive skin.

The invention discloses a composite hydrogel dressing based on gradient freeze thawing and a preparation method and application thereof, and belongs to the technical field of biomedical materials.The preparation method of the composite hydrogel dressing comprises the following steps that a polyvinyl alcohol solution and a polyvinylpyrrolidone solution are mixed, and a binary composite precursor solution is obtained; mixing sericin powder with the binary composite precursor solution to obtain a ternary composite precursor solution; injecting the ternary composite precursor solution into a mold, and preparing by adopting a gradient freeze thawing method to obtain ternary composite hydrogel; and dipping the ternary composite hydrogel in a potassium guaiacol sulfonate solution to form the composite hydrogel dressing loaded with the potassium guaiacol sulfonate. The composite hydrogel dressing prepared by the invention has multiple functions of excellent mechanical properties, good biocompatibility, adhesion, drug release ability, antibacterial ability and the like, and can be used for wound healing.

This invention relates to the field of dressing technology, specifically to a medical aesthetic skin wound dressing and its preparation process. The preparation process of a medical aesthetic skin wound dressing includes: preparation of an antibacterial repair agent, preparation of a modified graphene oxide solution, preparation of modified carboxymethyl chitosan, and preparation of a wound hydrogel dressing. The dressing of this invention incorporates an antibacterial repair agent with a conjugated microporous network structure, providing dual potent antibacterial effects through physical confinement and chemical action, creating a sterile microenvironment for wound repair; it uses sericin-hydroxypropyl cellulose modified graphene oxide to solve problems of poor dispersibility and insufficient compatibility, enhancing moisturizing and cell repair activity; and it uses tetramethylolphosphonium sulfate as a crosslinking agent to construct a hydrogel framework, locking in components such as ε-polylysine hydrochloride, resulting in multi-component synergistic antibacterial action and promotion of epidermal regeneration, precisely meeting the needs of delicate, rapid, and scarless healing of medical aesthetic wounds.

The invention belongs to the technical field of pharmacy, and particularly relates to minoxidil liniment as well as a preparation method and application thereof. The minoxidil liniment comprises the following components: minoxidil, an alcoholic solution, a stabilizer, an oat extract and water, wherein the stabilizer comprises EDTA (Ethylene Diamine Tetraacetic Acid)-tetrasodium, panthenol and hydroxypropyl cellulose. By utilizing the synergistic effect of the EDTA-tetrasodium, the panthenol and the hydroxypropyl cellulose, the preparation process is optimized, so that the effectiveness and the stability of the minoxidil serving as the raw material medicine can be effectively improved, the validity period of the minoxidil can be prolonged, and the medication compliance can be improved. According to the liniment disclosed by the invention, the oat extract is adopted as an auxiliary material of the liniment, so that side effects of minoxidil are reduced, red and swollen, pruritus and discomfort possibly caused by minoxidil can be effectively relieved, damaged scalp skin barriers are helped to be repaired, microinflammation around hair follicles is reduced, and a healthier environment is created for hair growth.
