Definitions

  • the present invention relates to liquid detergents containing Surfactants, anti-corrosion agents and other additives that enhance cleaning as well as their use for cleaning medical instruments, in particular for cleaning flexible endoscopes.
  • Endoscopes are tubular or tubular instruments that are used for examination of body cavities and hollow organs. You are with one optical system, consisting of lens and eyepiece, a lighting device and mostly flushing and suction devices as well as channels for inserting special ones Instruments.
  • Flexible endoscopes (which are also called fiber endoscopes are equipped with an optical fiber, which consists of a tightly packed bundle of hair-fine and therefore highly flexible individual fibers. Due to the flexibility of the glass fibers, light and image can be used on virtually any Angle be transmitted.
  • In addition to the fiber bundles and the Bowden cables for the movement of the tip are channels for water flushing and air as well as one in the Usually larger biopsy and suction channel housed at the same time.
  • Endoscopy can be used on its own, for example to take tissue samples, however also in combination with other methods, such as.
  • Endosonography ultrasound diagnostics
  • X-ray diagnostics are in use for example X-ray contrast images of the gallbladder and bile ducts and the pancreatic duct system.
  • B. as part of an endoscopic retrograde cholangiography (ERC) or an endoscopic retrograde Cholangiopancreatography (ERCP) - an X-ray contrast agent under X-ray control introduced into the duct system to be examined.
  • ERP endoscopic retrograde cholangiography
  • ERCP endoscopic retrograde Cholangiopancreatography
  • X-ray contrast media are agents for improving the radiographic Representation of body spaces, hollow organs and vessels. You absorb X-rays either weaker (negative X-ray contrast agents) or stronger (positive x-ray contrast agent) as the surrounding body tissue.
  • the radio opaque (X-ray opaque) predominantly contain positive X-ray contrast media Elements of high atomic numbers (such as iodine and barium) because of their absorbency for x-rays is larger.
  • organic iodine derivatives derived from pyridines or aromatic carboxylic acids deduce used.
  • Examples include iodoxamic acid [3,3 '- (4,7,10,13-tetraoxahexadecanedioyldiamino) bis (2,4,6-triiodobenzoic acid)] and lotroxinic acid [3,3 '- (3,6,9-trioxaundecanedioyldiamino) bis (2,4,6-triiodobenzoic acid)].
  • infections are particularly important Microorganisms that are transmitted through the blood and mucous membranes, such as B. tuberculosis, hepatitis, HIV infections, salmonellosis, Yersinia infections, Dysentery and the like.
  • the cleaning agent according to the invention can also be used dried poorly soluble aromatic halogen compounds, such as. B. X-ray contrast medium residues, detach completely from the surfaces. Because of the engagement The cleaning agents according to the invention are flexible endoscopes even after months constant use in practice microbiologically still perfect. Thereby patient safety is significantly increased and the lifespan of these high quality medical devices.
  • the inventive Detergents especially for duodenoscopes, via the X-ray contrast media are preferably administered, one compared to the cleaners of the prior art Technology have much better cleaning performance. This allowed the Microbiological status of the duodenoscope (after subsequent disinfection) strong be improved.
  • the nonionic surfactant or surfactants are advantageously selected from the Group of alkyl ethoxylates, the alkyl group of which is a saturated or unsaturated, straight or branched chain alkyl group having 10 to 18, preferably 12 to 14 Is carbon atoms, preferably 2 to 15, in particular 5 to, per molecule 9, especially 7 contain ethylene oxide units.
  • Isotridecanol ethoxylate and / or fatty alcohol polyglycol ether are very particularly preferred.
  • the total amount of nonionic surfactants from the range of 1.0 to 20.0 wt .-%, preferably from 10.0 to 15.0 wt .-% selected, each based on the total weight of the preparations.
  • amino acids according to the invention are e.g. B. glutamic acid, which is characterized by the following structural formula: and / or pyrrolidone carboxylic acid (pyroglutamic acid), which is characterized by the following structural formula:
  • the total amount of amino acids is advantageous from the range from 0.1 to 10.0% by weight, preferably from 0.5 to 2.0% by weight selected, each based on the total weight of the preparations.
  • the cleaning agents according to the invention can also contain amphoteric surfactants.
  • Amphoteric surfactants are surfactants that have both acidic and basic hydrophilic groups and thus behave acidic or basic depending on the condition.
  • Advantageous for the purposes of the present invention are, for example, amphoteric surfactants based on aliphatic polyamines with carboxy, sulfo or phosphono side chains, such as R ⁇ NH ⁇ (CH 2 ) n ⁇ COOH.
  • z. B. amphoteric surfactants the alkyl group of which is saturated or unsaturated, straight or branched chain alkyl group having 10 to 18, preferably Is 12 to 14 carbon atoms.
  • Amphoteric surfactants from the group of amphopropionates such as, for. B. the cocobetaine amido amphopropionate, which is characterized by the following structure:
  • the total amount of amphoteric surfactants in the range from 1.0 to 10.0% by weight, preferably from 2.0 to 5.0% by weight selected, based in each case on the total weight of the preparations.
  • the cleaning agents according to the invention can be in the form of liquid concentrates are available and packaged in dosing bags, for example, so that a Ready-to-use solution can be freshly prepared. It is particularly advantageous if the pH of the concentrate is between 5 and 9.
  • the liquid concentrates are preferably diluted with water to a working solution. Are preferred Ready-made solutions containing 0.5 to 5% by weight of cleaning agents according to the invention contain.
  • the working solution preferably has a pH between 6 and 8 ⁇ m to achieve optimal protection of the sensitive material.
  • the cleaning agents according to the invention can also advantageously be customary Corrosion inhibitors, such as benzotriazole, contain, especially if they when used with metallic surfaces, especially with non-refined ones Steels or materials made of non-ferrous metal alloys. It it is preferred that the content of one or more corrosion inhibitors is between 0.1 and 5% by weight, based on the total weight of the formulation.
  • customary Corrosion inhibitors such as benzotriazole
  • the cleaning agents according to the invention can advantageously be added Complexing agents and / or pH regulators contain the negative influence to reduce fluctuating water hardness or to ensure that the pH value of the cleaning agent is in an area that the sensitive material does not harms.
  • the inventive Cleaning agents for such preparations are common preservatives, dyes, Contain fragrances and / or other usual auxiliary substances.
  • the majority of these wear of the cases do not contribute to the cleaning effect, but serve for storability as well aesthetic purposes.
  • the amounts of such carriers and perfume to be used can be in Dependent on the type of the respective product by the specialist by simple Trying out can be easily determined.
  • a pH of 8 is set.
  • a pH of 8 is set.
  • a pH of 8 is set.
