InactiveCN101785873APromote bone healingPromote healingAbsorbent padsBandagesCraniotomyTrauma care
The invention relates to a biocompatible bleed-stopping and bone healing promoting material and a preparation method thereof. The material is applied to the bone surface or bone section of a human body or an animal, and is characterized in that the biocompatible bleed-stopping and bone healing promoting material is modified starch prepared by modifying natural starch serving as a raw material, and comprises one or more than two of modified starch granules, modified starch sponges, modified starch films, modified starch foams or modified starch glues, wherein the molecular weight of the modified starch is 15,000 to 10,000,000, and the water absorption rate is 1 to 100 times; in the natural starch serving as the raw material, the content of the amylopectin is at least no less than 70 percent of the total amount of the raw material. The invention fulfills the aim of stopping bleeding through direct spraying, daubing and pasting the biocompatible bleed-stopping and bone healing promoting material to touch the bone bleeding surface of wound; meanwhile, the biocompatible bleed-stopping and bone healing promoting material has a function of promoting bone healing, and can be used in the bleed stopping in the sternotomy of Cardio-Thoracic Surgery, spinal surgeries and joint surgeries of orthopedics department, Craniotomy and maxillo-facial surgery and the bleed stopping in the process of trauma care.

Nano-silver antibacterial gel with chitosan-poloxamer as gel matrix and preparation method and application of nano-silver antibacterial gel

The invention belongs to the technical field of nano-silver antibacterial gel, and discloses a preparation method and application of nano-silver antibacterial gel with chitosan-poloxamer as the gel matrix. The nano-silver antibacterial gel is characterized by being prepared through the following specific steps of adding poloxamer to a silver nitrate aqueous solution to be evenly stirred, adding trisodium citrate, irradiating the mixture with ultraviolet light after even stirring to obtain a nano-silver stock solution, adding a glacial acetic acid solution and glycerol to the nano-silver stock solution to be evenly stirred, adding poloxamer and chitosan to obtain nano-silver chitosan-poloxamer sol, regulating pH, and standing to make the mixture gelated to obtain the nano-silver antibacterial gel. According to the gel, chemical crosslinking is replaced with physical crosslinking, the problem that because harmful chemical reagents and other cross-linking agents are introduced, cytotoxicity rises is avoided, nano-silver is introduced by using chitosan and poloxamer in a combined mode as a carrier, the gel is stable and low in toxicity, and the gel can be applied to scalded wound surfaces and has great benefits for prognosis and outcome of patients.

Diabetic toe separators

InactiveUS20050177085A1Promote healingPrevent developmentNon-surgical orthopedic devicesFoot protectorInternal layer
Toe separators for use by a diabetic patient to maintain the toes separated, even when wearing shoes, to prevent the development of sores on the toes resulting from abrasion, and to promote healing are disclosed. In a preferred embodiment, there is provided a generally flat sole insert for protecting the user's heel, wherein the insert is further provided with a plurality of upwardly projecting toe dividers for keeping the toes separated. The dividers effectively separate the user's toes to prevent rubbing while allowing the user to walk wearing shoes. In various alternate embodiments, there are disclosed individual soft toe caps that may be individually placed over one or more individual toes to protect and separate the toes. In still another alternate embodiment, the individual toe separators may be fabricated as double-wall caps formed by inner and outer layers of a soft, FDA approved silicon material, and adapted to be filled with water or other suitable liquid or a gel. According to another aspect, the present invention provides a foot protector to be worn on the foot of a patient. The foot protector preferably incorporates one or more water-filled toe protectors for separating the toes as generally described above. Each of the embodiments may define a plurality of ventilation holes formed by welding of inner and outer portions. Any of the embodiments disclosed herein may further include medicated powders to reduce friction and aid in healing ulcerations. The filled embodiments may further be cooled or heated to provide therapeutic cooling or warmth to the foot and toes.

Carbon nanotube (CNT) reinforced injectable antibacterial conductive nano composite haemostatic cryogel dressing as well as preparation method and application thereof

The invention relates to a carbon nanotube (CNT) reinforced injectable antibacterial conductive nano composite haemostatic cryogel dressing as well as a preparation method and application thereof. The preparation method comprises the following steps of firstly adding glycidyl methacrylate functionalized quaternized chitosan (QCSG) into a solvent, and preparing into a QCSG solution; adding a CNT and PF127 into a solvent, and preparing into CNT dispersion liquid; mixing the QCSG solution and the CNT dispersion liquid, meanwhile, adding an initiator solution and a TEMED (Tetramethylethylenediamine) solution, and uniformly mixing, so that mixed liquid is obtained; placing the mixed liquid at subzero 18 to subzero 20 DEG C, and carrying out a reaction for 18h to 24h, so that a cross-linked cryogel network in a frozen state is obtained; putting the cross-linked cryogel network in the frozen state into a solvent, and thawing, so that the CNT reinforced injectable antibacterial conductive nano composite haemostatic cryogel dressing is obtained. The cryogel dressing provided by the invention has high elasticity and ultrafast shape restoration capacity, can be used for quickly absorbing blood, and has photothermal antibacterial performance and the like.
