An antimicrobial lubricant combines an antimicrobial agent, preferably silver based, with a silicone lubricant. This is achieved by first formulating a lubricant solution that has a non-volatile silicone lubricant and a volatile solvent carrier. An antimicrobial agent is added to the lubricant solution. The solution is then subjected to ultrasonic energy so that the antimicrobial agent is uniformly mixed with the lubricant in the solution. The solution containing the antimicrobial lubricant may be sprayed onto a medical device, for example the outer surface of the catheter of a peripheral IV catheter. After the solvent flashes off, a coat of uniform antimicrobial lubricant is formed on the catheter surface. The antimicrobial lubricant coating facilitates the insertion of the catheter to a patient, and at the same time prevents the growth of microorganisms from the device and infection to the patient.

The invention relates to methods and materials that, for example, function to increase the barrier properties of containers including polymeric drug medication reservoirs and related containers such as infusion set tubing. Embodiments of the invention include aqueous container systems having containers coated with a composition selected to have one or more material properties including an ability to reduce the diffusion or permeation of compounds such as oxygen, carbon dioxide, and preservatives (e.g. phenol, benzyl alcohol and m-cresol) into or through a wall of the container.

The invention relates to a continuous water monitoring system, including components thereof, and a method relating thereto for continuously monitoring, in real-time, a water supply in order to detect contaminants therein. The system employs the use of a live culture of bioluminescent bacteria and suitable light detecting means.

A humid gas stream is dehumidified by bringing that stream into contact with the front surface of a hydrophilic capillary condenser layer that captures the water and moves it adjacent the rear surface of the capillary layer. An osmotic layer, such as a semi-permeable membrane, is disposed on the rear surface of the condenser layer, and an osmotic fluid having a low concentration of water therein, is disposed adjacent the osmotic layer. An osmotic driving force, resulting from the water concentration gradient across the osmotic layer, transports the condensed water from the condensing layer through the thickness of the osmotic layer and into an osmotic fluid. The osmotic layer also inhibits the osmotic fluid from flowing into the condenser layer.

Various features include enabling growth of microorganisms in a sample along with a reduction of sample debris that may interfere with microorganism detection, and reduction in toxicities that may inhibit microorganism growth. Further methods for selectively degrading non-viable microbial cells, are provided, for enhanced detection of viable microbial cells following a growth period.

A cooling water circulation apparatus capable of limiting attachment of microorganisms and scale in an environmentally friendly manner and a method of removing scale in the cooling water circulation apparatus. An electrolytic device 10 is provided on a cooling water circulation route R1. In the arrangement, mineral contents such as calcium ions and magnesium ions contained in cooling water W are deposited as scale S on an electrode 12A or 12B in an electrolytic step, thereby enabling the mineral contents to be removed from the cooling water W. Even if the hardness of the cooling water W is increased by evaporation of the water with elapse of time, the hardness can be reduced by the electrolytic processing. Thus, the deposition of the scale S in the circulation route R1 can be reduced. Further, the scale S deposited on the electrode 12A or 12B can be easily separated by operating while reversing the polarities of the electrodes 12A and 12B at predetermined time intervals.

This invention is directed to an synergistic antimicrobial composition which comprises a mixture of an iodopropynyl compound and a dimethyldithiocarbamate compound, said mixture provided in an amount sufficient to protect a substrate from attack by one or more microbial organisms. The composition can be used broadly in industrial systems and more particularly with substrates such as paints, coatings, plastics, wood and wood composites.

A low density food bar includes dried fruit pieces and a binder to produce a sponge-like consistency.

Conventional building materials such as plywood and wallboard are both widely used in residential and commercial interior construction and highly susceptible to mold and fungal growth when utilized in a moist environment or periodically subjected to wetting. Mold growth has been associated with certain health risks attributed to toxic airborne mold spores, unpleasant smells and, at best, is considered unsightly. The invention provides a two-part antifungal formulation prepared from at least a binder admixture and a preservative admixture that can be applied to surfaces and/or incorporated within materials that are susceptible to mold growth. The antifungal formulation forms an antifungal coating on, and in some instances at least partially through, the substrate that will both inhibit mold and fungal growth while improving the persistence of the antifungal effects and/or reducing the concentration of antifungal agents necessary to achieve a desired level of antifungal activity.

The invention generally relates to compositions and methods for preventing sternal wound infections, such as mediastinitis. In certain embodiments, the invention provides an antimicrobial composition including at least one bioresorbable polymer, such as a tyrosine-derived polyesteramide, and at least one antimicrobial agent, in which the composition is adapted to be topically applied to an esophageal perforation in a subject or a median sternotomy incision site in the subject, and in which the at least one antimicrobial agent is present in an amount effective to inhibit development of mediastinitis in the subject.

The present invention involves the use of photosensitizers to provide antibacterial surfaces on consumer and industrial items. This approach avoids the used of chemicals and solutions that may be toxic. The inventions also avoids the use of chemical compositions that might form degradation products which may be unacceptable to healthy persons or irritating to persons who may have allergies or are otherwise sensitized. According to the invention, photosensitizers with specific properties and specific design features are selected to make practical use of photosensitizers in the consumer and industrial market place. It is important to select a photosensitizer with an activation spectrum that is matched to the environmental conditions under which the surface to be protected is required to exhibit its antimicrobial properties. This means that the illumination energy and intensity levels expected need to yield enough singlet oxygen to destroy the targeted microbes. It is also possible to select photosensitizers that are activated only by wavelengths prominently present in certain illumination lamps, such as those lamps commonly present in a laboratories, medical offices, pharmacies and food service areas, thereby making the surfaces antimicrobial only on demand when the illumination lamps are turned on.
