摘要:
The invention is a process for cleaning and disinfection of heat and corrosion sensitive medical instruments, particularly endoscopes in which the surfaces of the medical instruments are contacted with a detergent and disinfectant solution. The solution has a pH of from 6 to 8 and contains a low foaming nonionic surfactant, a proteolytic enzyme, a complexing agent, and an aldehyde selected from the group consisting of formaldehyde and aliphatic dialdehydes containing 2 to 8 carbon atoms and, optionally, other standard detergent and disinfectant constituents. The cleaning solution is heated to 55.degree. to 65.degree. C. and kept at that temperature for 1 to 15 minutes during contact with the surfaces of a medical instrument. The surfaces are rinsed at least twice with water, the water being heated to 55.degree. to 65.degree. C. at least in the last rinse cycle and the medical instruments are dried with sterilized hot air at a temperature of 40.degree. to 60.degree. C. Water having a hardness of 3.degree. to 8.degree. Gh is used.

摘要:
In the process disclosed, medical molding materials are treated with an aqueous solution of a disinfectant which contains, in addition, 0.1 to 15 wt.% of a soluble alcohol. This ensures high dimensional stability and good surface quality of the mold, even in the case of critical molding materials as alginates.

摘要:
Phosphonocarboxylic acids, such as phosphonosuccinic acid and especially 2-phosphonobutane-1,2,4-tricarboxylic acid, and aminopolycarboxylic acids, advantageously tetrasodium trimethylene diamine tetracetate or trisodium nitrilotriacetate, are added to aqueous or aqueous solvent-containing disinfectant solutions based on aldehydes and quaternary ammonium compounds for corrosion inhibition and pH-adjustment to 3.5-4.0, respectively. The corrosion inhibiting effect of the two salts is synergistic.
