4547 results about "Antimicrobial" patented technology

An antimicrobial is an agent that kills microorganisms or stops their growth. Antimicrobial medicines can be grouped according to the microorganisms they act primarily against. For example, antibiotics are used against bacteria and antifungals are used against fungi. They can also be classified according to their function. Agents that kill microbes are called microbicidal, while those that merely inhibit their growth are called biostatic. The use of antimicrobial medicines to treat infection is known as antimicrobial chemotherapy, while the use of antimicrobial medicines to prevent infection is known as antimicrobial prophylaxis.

Sensitive and rapid determination of antimicrobial susceptibility

The present invention relates to moving microorganisms to a surface, where they are grown in the presence and absence of antimicrobials, and by monitoring the growth of the microorganisms over time in the two conditions, their susceptibility to the antimicrobials can be determined. The microorganisms can be moved to the surface through electrophoresis, centrifugation or filtration. When the movement involves electrophoresis, the presence of oxidizing and reducing reagents lowers the voltage at which electrophoretic force can be generated and allows a broader range of means by which the target can be detected. Monitoring can comprise optical detection, and most conveniently includes the detection of individual microorganisms. The microorganisms can be stained in order to give information about their response to antimicrobials.

Inherently antimicrobial quaternary amine hydrogel wound dressings

A composition and method for treating a wound with an inherently antimicrobial dressing. The dressing is a hydrogel containing from about 15 to 95 percent, and preferably from about 61 to 90 percent, by weight of a cationic quaternary amine acrylate polymer prepared by the polymerization of acryloyloxyethyl(or propyl)-trialkyl(or aryl)-substituted ammonium salts or acrylamidoethyl(or propyl)-trialkyl(or aryl)-substituted ammonium salts. The antimicrobial hydrogels are non-irritating to the wound, absorb wound exudate, and, due to the inherently antimicrobial properties, enhance the sterile environment around the wound. The hydrogels have sufficient adhesive properties that loose contact with the wound is assured but can also be removed without leaving any gel residue on the wound. The wound dressings are preferably formed on a substrate, such as a web or patch, for ease in application to and removal from the wound. If desired, additional antimicrobial or other pharmaceutically active agents can also be incorporated into the hydrogel structure.

Antimicrobial brush

A brush having antimicrobial characteristics that inhibit bacterial growth. The antimicrobial agents, compounds or chemicals are embedded in either the body or bristles or both of the brush. Further, the present invention is a method of manufacturing a brush having antimicrobial characteristics that inhibit bacterial growth. An antimicrobial additive is incorporated in resin concentrate form into the amorphous zones of the molecular structure of the polymer from which brush handles are injection molded, thereby incorporating the antimicrobial agent into the brush handle. The antimicrobial additive in the body of the brush, incorporated in the manner above, results in substantive controlled migration from the body to the bristles, until a point of equilibrium is reached. The invention is suitable for any brush in which bristles are embedded in plastic, including toothbrushes, hair brushes, scrub brushes, toilet bowl brushes, cosmetic brushes, lip-color brushes, etc.

High viscosity antibacterials

An antibacterial fluid may be applied to a tubular medical cannula for access to a patient. The fluid comprises a typically metabolizable antibacterial formulation having a viscosity of at least about 5,000 cp. The cannula may then be inserted into the patient with an increased lubricity for a reduction of pain, while at the same time, unlike silicones, preferred materials do not readily accumulate in the patient. The tubular medical cannula may be a rigid, hollow needle, sharp or blunt, a spike, or a flexible catheter. Also, the viscous antibacterial fluid may be used to lock a catheter or other cannula while implanted in the patient, for storage purposes.
