Abstract:
In the method for cleaning and/or disinfecting hard surfaces with an aqueous foam, comprising cleaning and/or disinfecting agents, the foam is generated by means of mixing water, air and a concentrated cleaning and/or disinfecting agent in a mixer unit (1). The concentration of the cleaning and/or disinfecting agent in said foam, based on water used, is recorded and/or monitored. The use of concentrated cleaning and/or disinfecting agent per unit time is continuously measured and the concentration of the cleaning and /or disinfecting agent in the foam is determined therefrom and from the use of water per unit time. A continuous, simple, rapid and error-free determination and monitoring of the concentration of the cleaning and/or disinfecting agent in the cleaning and/or disinfecting foam is thus possible.
Abstract:
A disinfecting and deodorizing agent which comprises an aqueous solution containing 10 to 1000 ppm of a chlorine-containing oxidizing agent and having a pH adjusted to 8 to 13 with an inorganic or organic salt; a method for disinfection and deodorization which comprises applying the disinfecting and deodorizing agent into air or to an article to be disinfected and deodorized by a prescribed means; and a tool for disinfection and deodorization which is equipped with a container for the disinfecting and deodorizing agent having a prescribed spraying means and is designed so as to spray the disinfecting and deodorizing agent by the spraying means in the state of a mist wherein the number of droplets having a particle diameter of 10 mu or less is 2 % or less as determined with frequency distribution.
Abstract:
A system (10) to provide a specified volume of a medical fluid (23) from a bulk source (14) to a dose and/or delivery container (16) for injection into a patient. The fluid path (50, 100) between the bulk container (14) and the delivery container (16) is physically separated at a connecting site (66) before fluid (23) is injected from the delivery container (16) into the patient. The bulk container (14) may be a bag or bottle, and the delivery container (16) may be a syringe (81) or bag (28). A bag (28) delivery container (16) may be contained in a pressurizeable chamber (30) and fluid (23) may be delivered by providing pressure to a membrane (52) in the chamber (30) contacting a wall of the bag (28). The system (10) may be automated.
Abstract:
The present invention provides bioerodable constructs for controlled release of bioactive materials. In a preferred mode, the constructs may be utilized adjacent to a biological surface. The constructs are based on a blend of two or more poly(ester-amide) polymers (PEA). Such polymers may be prepared by polymerization of a diol (D), a dicarboxylic acid (C) and an alpha-amino acid (A) through ester and amide links in the form (DACA)n. An example of a (DACA)n polymer is shown below in formula II. Suitable amino acids include any natural or synthetic alpha-amino acid, preferably neutral amino acids.
Abstract:
The invention relates to the use of ester peroxy acids for improving surface perfusion during the disinfection of surfaces and to synergistic antimicrobial combinations of ester peroxy acids and additional constituents.
Abstract:
A method of treating a subject infected with a virus or a method of preventing viral infection of a subject comprising administering to the subject an effective amount of a compound having structure (1), wherein L=L'= 2-methylimidazole
Abstract:
The invention relates to a method for treating bio-film on ocean based seismographic equipment, the method being characterised in including the step of applying electrochemically activated, anion-containing solution to the bio-film bearing equipment.
Abstract:
The continuous process for hyperactivation of fluids for sterilization uses a sterilizing fluid which is mixed with a gas that is inert with respect to the fluid. A sterilizing mixture is obtained which is subsequently evaporated by means of introduction into an evaporation tube in a condition of annular motion, where a liquid phase of the mixture flows against the heated walls of the evaporator at a slower speed than the gaseous phase thereof, which flows in the central zone of the evaporator, internally of the liquid phase. A gaseous vapour/inert gas mixture is thus obtained, which is subjected to a waiting period during which the mixture flows through a transit device which transfers it to a sterilization chamber, a temperature of which is lower than a dewpoint temperature of the gaseous mixture, where a product is sterilized.
Abstract:
The invention relates to a method for sterilising packages (22) by means of a liquid sterilising agent (9) containing peracetic acid at a concentration of between 0.1 % and 1.5 %. The sterilising agent wets the surfaces (22) to be sterilised, kills off the bacterial spores and is then removed. To be able to sterilise the packages (22) in less than 2 minutes and if possible by heating the packages only little, preferably by less than 10 DEG C, the invention provides for the sterilising agent (9) to be atomized into an air current (in 6), for the mist (18) to be heated to a temperature of between 25 DEG C and 80 DEG C by the input of heat (in 12) and, using the air as a vector, to be blown in the gas phase (13, 19, 25) onto the surface (22) to be sterilised which has a temperature of between 10 DEG C and 30 DEG C so that the condensable constituents of the gas are able to condense on said surfaces (22).
