Definitions

  • the present invention relates to the use of liquid detergents containing surfactants, corrosion inhibitors and other additives that enhance cleaning for cleaning medical instruments, in particular for cleaning flexible endoscopes by removing X-ray contrast agents.
  • Endoscopes are tubular or tubular instruments used to examine body cavities and hollow organs. They are equipped with an optical system consisting of lens and eyepiece, a lighting device and usually rinsing and suction devices and channels for introducing special instruments.
  • Flexible endoscopes (which are also referred to as fiber endoscopes) are equipped with a fiber optic light guide, which consists of a tightly packed bundle of hair-thin and therefore highly flexible individual fibers. Due to the flexibility of the glass fibers, light and image can be transmitted via virtually any bend.
  • the fiber bundles and the Bowden cables for the movement of the tip channels for flushing and air and a generally larger biopsy and at the same time suction duct are housed.
  • the endoscopy alone, for example, for the removal of tissue samples, but also in combination with other methods, such.
  • ultrasound endoscopic ultrasonography
  • X-ray diagnostics are performed.
  • X-ray contrast images of the gallbladder and the bile ducts and of the pancreatic duct system are commonly used. This is -. B. in the context of an endoscopic retrograde cholangiography (ERC) or an endoscopic retrograde cholangiopancreatography (ERCP) - introduced an X-ray contrast agent under X-ray control in the duct system to be examined.
  • ERP endoscopic retrograde cholangiography
  • ERCP endoscopic retrograde cholangiopancreatography
  • X-ray contrast agents are agents for improving the radiographic representation of body spaces, hollow organs and vessels. They absorb X-rays either weaker (negative X-ray contrast agents) or stronger (positive X-ray contrast agents) than the surrounding body tissue.
  • the radiopaque (i.e., radiopaque) positive X-ray contrast agents contain predominantly high atomic number elements (such as iodine and barium) because their X-ray absorptivity is greater.
  • organic iodine derivatives derived from pyridines or aromatic carboxylic acids are typically used.
  • iodoxamic acid [3,3 '- (4,7,10,13-tetraoxahexadecanedioyldiamino) -bis (2,4,6-triiodobenzoic acid)] and [3,3' - (3,6,9-trioxaundecanedioyldiamino)] bis (2,4,6-trüodbenzoeklare)].
  • Endoscopies mostly take place in microbially colonized areas of the body.
  • a transmission of pathogens by contaminated endoscopy itself and by endoscopic accessories has been proven many times.
  • infections with a long incubation period are very difficult and usually impossible to detect in practice.
  • patients whose illness is dumb or unrecognized come into contact with endoscopes.
  • infections with microorganisms whose transmission takes place through the blood and mucous membranes, such.
  • tuberculosis hepatitis, HIV infections, salmonellosis, Yersinia infections, dysentery and the like.
  • liquid cleaning agents for cleaning of flexible endoscopes which contain surfactants in addition to essentially organic solvents, acids or alkalis, and sometimes also enzymes.
  • surfactants in addition to essentially organic solvents, acids or alkalis, and sometimes also enzymes.
  • the compounds mentioned have some disadvantages:
  • liquid cleaners are relatively effective at removing blood and secretion residues as well as at the separation of fat and other hydrocarbonaceous compounds. However, they are not suitable for completely removing residues of X-ray contrast agents.
  • the object of the invention is therefore to develop a liquid cleaning agent for the removal of X-ray contrast agents, which does not have the disadvantages of the prior art, which thus shows a good cleaning performance at the same time high material compatibility and also for the removal of X-ray contrast agents, such.
  • X-ray contrast agents such as organic, aromatic iodine derivatives, in particular from flexible endoscopes.
  • cleaning agents also dried on sparingly soluble aromatic halogen compounds such.
  • the use of the cleaning agent according to the invention especially in duoendoscopes over which X-ray contrast agents are preferably administered, has a significantly better cleaning performance than the cleaners of the prior art. This greatly improved the microbiological status of duoendoscopes (after subsequent disinfection).
  • the nonionic surfactant or surfactants are selected from the group of alkylethoxylates whose alkyl group is a saturated or unsaturated, straight or branched chain alkyl group having 10 to 18, preferably 12 to 14 carbon atoms, preferably 2 to 15, in particular 5 to 9, per molecule , especially containing 7 ethylene oxide units.
  • alkylethoxylates whose alkyl group is a saturated or unsaturated, straight or branched chain alkyl group having 10 to 18, preferably 12 to 14 carbon atoms, preferably 2 to 15, in particular 5 to 9, per molecule , especially containing 7 ethylene oxide units.
  • isotridecanol ethoxylate and / or fatty alcohol polyglycol ethers are particularly preference.
  • the total amount of nonionic surfactants is selected from the range of 1.0 to 20.0 wt .-%, preferably from 10.0 to 15.0 wt .-%, each based on the total weight of preparations.
  • the pyrrolidonecarboxylic acid (pyroglutamic acid), which is characterized by the following structural formula: used.
  • the total amount of the amino acid is selected from the range of 0.1 to 10.0 wt .-%, preferably from 0.5 to 2.0 wt .-%, each based on the total weight of the preparations.
  • the cleaning agents used according to the invention can be further Amphoteric surfactants included.
  • Amphoteric surfactants are surfactants that possess both acidic and basic hydrophilic groups and thus behave acidic or basic depending on the condition.
  • amphoteric surfactants based on aliphatic polyamines having carboxy, sulfo or phosphono side chains, for example R-NH- (CH 2 ) n -COOH are advantageous.
  • amphoteric surfactants whose alkyl group is a saturated or unsaturated, straight or branched chain alkyl group having 10 to 18, preferably 12 to 14 carbon atoms.
  • amphoteric surfactants from the group of amphopropionates such as. Cocobetainamido amphopropionate, which is characterized by the following structure:
  • the total amount of amphoteric surfactants is selected from the range of 1.0 to 10.0 wt .-%, preferably from 2.0 to 5.0 wt .-%, each based on the total weight of the preparations ,
  • the detergents used according to the invention can be in the form of liquid concentrates and packaged, for example, in dosing bags, so that a use solution can be prepared fresh in each case. 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 use solution. Preference is given to the use of working solutions containing 0.5 to 5 wt .-% of cleaning agent according to the invention.
  • the use solution preferably has a pH between 6 and 8 in order to achieve optimal protection of the sensitive material.
  • the cleaning agents used according to the invention can also advantageously contain conventional corrosion inhibitors, such as, for example, benzotriazole, in particular if they can come into contact with metallic surfaces, in particular with non-refined steels or materials of non-ferrous metal alloys, when used. It is preferred to choose the content of one or more corrosion inhibitors between 0.1 and 5 wt .-%, based on the total weight of the formulation.
  • conventional corrosion inhibitors such as, for example, benzotriazole
  • the cleaning agents used according to the invention may advantageously additionally contain complexing agents and / or pH regulators in order to reduce the negative influence of fluctuating water hardness or to ensure that the pH of the cleaning agent is within a range which does not damage the sensitive material.
  • the cleaning agents used according to the invention for such preparations may contain customary preservatives, dyes, fragrances and / or other customary auxiliaries. These contribute in the majority of cases not to the cleaning effect, but serve the storage and aesthetic purposes. However, it is also possible to use those components which develop a (preservative, nourishing effect and at the same time provide for a particular color and / or a pleasant fragrance.
