  • Page 6: Course Objectives

    Course objectives Discuss cleaning theory Describe a basic wash program Understand the fluid flow paths Interpret electrical schematics Identify key components Identify normal menus Access service mode Troubleshoot fault codes and errors Review maintenance procedures...
  • Page 7 Law of mass cleaning action The law of mass cleaning action expresses a relationship between time, action, concentration, and temperature in the process of removing soils. This laws states that if you decrease any one of these factors, we must increase one or more of the remaining factors in order to maintain equal cleaning ability...
  • Page 8 4 key factors for cleaning efficacy Chemicals...
  • Page 9 Chemistry - soil To properly clean something you need an understanding of the soil Inorganic Soils Organic Soils Water spots, lime animal fats, body scale, rust, oils, carbohydrates, corrosion, oxidation, proteins, bacteria, minerals, rocks mold, yeast, slime USE ACID USE ALKALINE CLEANERS CLEANERS Combination Soils...
  • Page 10 Chemistry - pH pH – This is a measure of the concentration of hydrogen ions (H+) in relation to the concentration of hydroxyl ions (OH-)
  • Page 11 Chemistry – cleaning power pH is a very important part of cleaning power. The reality is many hospitals choose to use pH neutral products. These products contain some of the following to perform the cleaning task: Solvents Surfactants Enzymes Chelating agents...
  • Page 12 Chemistry - solvents Solvent All cleaners require some sort of liquid solvent. This solvent not only "dissolves" the soil, but also provides a medium in which soil can be suspended and carried away from the surface. Water is the oldest, least expensive and most widely used cleaning solvent known to man.
  • Page 13 Chemistry - surfactants Surfactant: sur·fac·tant a.k.a - detergents or soaps The word surfactant is short for "surface active agent". Surfactants work at the boundary layer (the interface) between the soil and the solvent. Each surfactant molecule has two chemical groups; one that is attracted to water (the hydrophile) and one that is attracted to soil (the hydrophobe).
  • Page 14 Chemistry – Enzymes Protease (enzymes) Proteases can either break specific peptide bonds (limited proteolysis), depending on the amino acid sequence of a protein, or break down a complete peptide to amino acids (unlimited proteolysis). The activity can be a destructive change, abolishing a protein's function or digesting it to its principal components.
  • Page 15 Chemistry - Enzymes For example coagulated blood protein: fibrine-network is degraded to smaller parts that can be removed easlily There are an endless number of different enzymes with different properties (different target molecules, pH, temperature, stability etc.)
  • Page 16 Chemistry- chelating agents Chelating agents (che-lating) "tie up" the hardness in water. Dissolved minerals in water are the cause of hardness. Rain and distilled water is pure and soft, but it quickly dissolves minerals (mainly calcium, magnesium, iron and silica) as it soaks into the ground and travels through rivers or lakes.
  • Page 17 Basic wash program – pre-wash Step 1 - Pre-wash ~ 2 min The maximum allowed temperature is 45C for all Pre-wash steps. Cold water will help prevent coagulation of blood onto the device. If the water temperature increases to above 45C error code 163 “Water too warm”...
  • Page 18 Basic wash program - wash Step 2 - Wash ~ 5 min Warm Water is mixed with the cleaning agent or detergent. If the water temperature increases by more than 8C error code 163 “Water too warm” will be flashed and the process is interrupted.
  • Page 19 TOSI testing...
  • Page 20 Basic wash program - rinse Step 3 - Rinse ~ 1 min Warm Water is used to rinse off the cleaning agent or detergent. The length and number of rinse repeat steps will be determined by the detergent products rinse ability.
  • Page 21 Basic wash program – clean rinse Step 4 - Clean Rinse ~ 1 min DI/RO is used with instrument lubricant added (optional) Only in models since ~2009, pre-2009 add lubricant directly to the thermal disinfect step AAMI 7.5.4 “the final rinse should be performed with treated water that is of a quality that does not contribute to staining or contamination of the instrument.”...
  • Page 22 Basic wash program – thermal disinfect Step 5 – Thermal Disinfect A =3000 ~ 10 min DI/RO helps maintain instrument luster The Robert Koch institute in Germany states, “all medical products should be disinfected to an A = 3000” = 3000 has been proven effective against heat resistant viruses such as Hepatitis-B...
  • Page 23 Basic wash program – dry Step 6 - Dry ~ 8 min Temperature setting of 130C is recommended. Dry instruments reduce the chance of wet- packs from the sterilizers. Some instruments are more difficult to dry than others. We recommend that careful analysis be done to determine if minor hand drying of plastic instruments might be a better option over lengthening the drying...

    Cycle times • Effective cycle times. No shortcuts. Belimed 31 min Cycle Step cycle Pre-wash 2 minutes Wash 5 minutes Rinse 1 minute Clean Rinse 1 minute Thermal Rinse 2.5 minutes 8 minutes Total Active time 19.5 minutes (sum of above five step times)
  • Page 25 Washing concepts Single wash pump Optimizing the water level is significantly simpler using a single pump. Wash Principles By using a high volume of water under low pressure we allow the water/detergent mixture sufficient contact time to perform the cleaning task.
