MOLD FOR MOLDING POLYURETHANE CONDOM, AND PREPARATION METHOD AND USE METHOD FOR MOLD
The present disclosure provides a mold for molding a polyurethane condom, and methods for manufacturing and using the mold. The mold (200) has a surface roughness of 0.2 or less, is formed from a thermoplastic polymer having a surface tension of 10-35 mN/m. The mold (200) for molding a polyurethane condom is prepared by injection molding the thermoplastic polymer. When the mold (200) is used, the mold (200) is hung vertically and dipped in an emulsion containing a polyurethane resin to obtain a dipped mold (200), then the dipped mold (200) is removed and dried to form a polyurethane film on its surface, and then demolded to obtain a polyurethane condom (100). The condom formed by the mold (200) is thin and has excellent flexibility and strength, satisfying the market demand for the product.
Synergistic antibacterial activity of medium polarity oils in combination with antibacterial agents on bacterial biofilms
The compositions of the present invention comprise at least one medium polarity oil and at least one antibacterial agent, the combination of which produces a synergistic antibacterial effect against bacterial biofilms. Methods are disclosed for the reduction of bacteria in and/or elimination of bacterial biofilms on biological and non-biological surfaces, as well as methods for the treatment of wounds, skin lesions, mucous membrane lesions, and other biological surfaces infected or contaminated with bacterial biofilms.
Polytetrafluoroethylene co-polymer emulsions
The present disclosure is directed to a class of fluorinated copolymers, such as PTFE copolymers, that can be dissolved in low toxicity solvents, such as Class III Solvents, and that enable the creation of stable water-in-solvent emulsions comprising the fluorinated copolymers dissolved in a low toxicity solvents and a hydrophilic agent (e.g., a therapeutic agent) dissolved in an aqueous solvent, such as water or saline.
Operating room coating applicator and method
The present disclosure provides a coating applicator operable to apply a coating of a therapeutic agent upon an object comprising an openable and sealable device compartment, a therapeutic agent positioned in communication with the device compartment, an atomizer operable to atomize the therapeutic agent, and a source of vacuum in communication with the device compartment. The coating applicator may further comprise a drier, and the drier may comprise an arrangement to operate the source of vacuum for a time sufficient to promote drying of applied therapeutic agent. Deposition of the atomized therapeutic agent may be promoted by contacting the atomized therapeutic agent while the object is in a chilled condition and by contacting the object with atomized therapeutic agent while the atomized therapeutic agent is in a heated condition. Related methods are also disclosed.
Osteoconductive coating of implants made of plastic
The invention relates to biomaterials based on plastics, such as polyaryl polyether ketone (PEK), and to methods for producing and using same. The following describes how a mechanically stable coating made of a porous bone substitute material, e.g. Nano Bone®, is applied to polyaryl polyether ketone (PEK), e.g. polyether ether ketone (PEEK), as a result of which the problem of poor cell adhesion on plastics surfaces of this kind can be solved. The bone substitute material can be applied both dry as a powder and also in a wet spraying method. The coating is a result of briefly melting the polymer surface and the resulting partial penetration of the previously applied layer. In the process, the molten polymer penetrates into nanopores of the bone substitute material and thus establishes a firm connection.
Abradable therapeutic coatings and devices including such coatings
A method of reducing surgical site infection (SSI), using a coated medical device having a tissue penetrating surface and an abradable coating on the medical device comprising at least one antimicrobial agent in the coating.
BIODEGRADABLE SUPPORTING DEVICE
A biodegradable in vivo supporting device is disclosed. In one embodiment, a coated stent device includes a biodegradable metal alloy scaffold made from a magnesium alloy, iron alloy, zinc alloy, or combination thereof, and the metal scaffold comprises a plurality of metal struts. The metal struts are at least partially covered with a biodegradable polymer coating. A method for making and a method for using a biodegradable in vivo supporting device are also disclosed.
BIOMATERIAL BASED ON ALIGNED FIBERS, ARRANGED IN A GRADIENT INTERFACE, WITH MECHANICAL REINFORCEMENT FOR TRACHEAL REGENERATION AND REPAIR
An implant can include a plurality of polymeric fibers associated together into a fibrous body. The fibrous body is capable of being shaped to fit a tracheal defect and capable of being secured in place by suture or by bioadhesive. The fibrous body can have aligned fibers (e.g., circumferentially aligned) or unaligned fibers. The fibrous body can be electrospun. The fibrous body can have a first characteristic in a first gradient distribution across at least a portion of the fibrous body. The fibrous body can include one or more structural reinforcing members, such as ribbon structural reinforcing members, which can be embedded in the plurality of fibers. The fibrous body can include one or more structural reinforcing members bonded to the fibers with liquid polymer as an adhesive, the liquid polymer having a substantially similar composition of the fibers.
Medical constructs including tubes and collagen fibers
