With manual cleaning, the two essential components are friction and fluidics. Friction e. Fluidics i. The most common types of mechanical or automatic cleaners are ultrasonic cleaners, washer-decontaminators, washer-disinfectors, and washer-sterilizers. Ultrasonic cleaning removes soil by cavitation and implosion in which waves of acoustic energy are propagated in aqueous solutions to disrupt the bonds that hold particulate matter to surfaces. Bacterial contamination can be present in used ultrasonic cleaning solutions and other used detergent solutions because these solutions generally do not make antibacterial label claims Even though ultrasound alone does not significantly inactivate bacteria, sonication can act synergistically to increase the cidal efficacy of a disinfectant Users of ultrasonic cleaners should be aware that the cleaning fluid could result in endotoxin contamination of surgical instruments, which could cause severe inflammatory reactions Washer-sterilizers are modified steam sterilizers that clean by filling the chamber with water and detergent through which steam passes to provide agitation.
Instruments are subsequently rinsed and subjected to a short steam-sterilization cycle. These units sometimes have a cycle that subjects the instruments to a heat process e. Washer-disinfectors are generally computer-controlled units for cleaning, disinfecting, and drying solid and hollow surgical and medical equipment. In one study, cleaning measured as 5—6 log 10 reduction was achieved on surfaces that had adequate contact with the water flow in the machine Detailed information about cleaning and preparing supplies for terminal sterilization is provided by professional organizations , and books Studies have shown that manual and mechanical cleaning of endoscopes achieves approximately a 4-log 10 reduction of contaminating organisms 83, , , Their whole line of cleaning supplies helps ensure your safety and preserve your investment.

Home How to Sterilize Medical Equipment. How to Sterilize Medical Equipment Written by Matt Anderson on Monday April 29, Sterilizing equipment is a vital element of modern medical care since patients come in contact with surgical tools, syringes and bandages all the time.
Benefits of Sterilizing Medical Equipment With invasive procedures, there's contact between a patient's mucous membranes or sterile tissue and a surgical instrument or medical device. Some benefits of sterilizing medical equipment include: It eliminates pus, blood, foreign particles and dirt left behind that could lead to dangerous complications for the next patient requiring surgery where the medical practitioner uses the instrument.
It decreases bioburden -- the number of non-sterilized bacteria living on a surface. It prevents the corrosion of expensive and highly precise tools that have delicate pivots and hinges. It removes the breeding ground for the surviving germs. It ensures the safe transport of equipment needing to be packed and assembled for sterilization or disinfection. The germ warfare strategy of the hospital consists of a few processes done in this precise order: Cleaning: Cleaning must always come before high-level sterilization or disinfection.
Disinfecting: This is the second step and can involve using liquid chemicals are used to kill non-spore forming bacteria. Sterilizing: You can employ several methods of sterilization to kill disease-causing microorganisms and eradicate transmissible agents, like bacteria and spores.
Whether equipment requires high-level sterilization, low-level disinfection or high-level disinfection depends on where it falls in these three categories: Critical objects: An example includes surgical instruments that come in contact with sterile tissue.
Semicritical objects: An example includes endoscopes that come in contact with mucous membranes. Noncritical objects: An example includes stethoscopes that come in contact with only intact skin. Methods for Sterilizing Medical Equipment Choosing the best sterilization method is extremely important when it comes to medical equipment. Some methods of sterilizing medical equipment are as follows.
Steam Sterilization Most sterile processing departments have steam sterilizers called autoclaves. Dry Heat Sterilization When steam cannot penetrate an instrument or can destroy it, your next logical option is dry heat. Chemical Sterilization Prepared chemical solutions are involved in this process. Some chemicals often used in sterilization are: Ozone Ethylene oxide Hydrogen peroxide Bleach These chemicals have the power to kill a broad range of pathogens and have properties that could be harmful to humans.
Plasma Gas Sterilizers This type of sterilization uses low temp hydrogen peroxide-based gas plasma inside a chamber to kill any microorganisms on dental and medical equipment, including spores, bacteria, fungi and viruses. Vaporized Hydrogen Peroxide VHP Sterilizers Like with plasma sterilization, you also use hydrogen peroxide vapor with VHP sterilizers, but you don't use plasma gas when within the sterilization process.
Sterilizing Accessories Some examples of accessories used for sterilization include the following: 1. Healthmark Clear Top Scope Sterilization Trays These sterilization trays are designed for sterilization, transportation and medical scope storage. Healthmark Plastic Instrument Sterilization Baskets These sterilization baskets are economical, lightweight alternatives to costly metal sterilization trays and professionals may use them for similar tasks.

Healthmark AWTK Washer Test Kits These washer test kits offer a set of testing supplies for determining the water quality, water temperature and cleaning capability of three- or four-level automated washers.
Healthmark Lint-Free Disposable Instrument Cleaning Wipes These disposable wipes are perfect for cleaning sensitive instruments and equipment like endoscopes before sterilization. There are more than 4, factories operating along the Citarum and its tributaries and the West Java Environmental Agency has so far been able to build a case against of them. But it is hard to build a strong case against them. They need to file a formal complaint. Then we can conduct a surprise inspection.
But Deni Riswandani, chairman of the not-for-profit organisation Elingan, said it is easier said than done. Some of these companies employ thugs to stop people from taking pictures of their discharge outlets. Dwina Roosmini, an environmental engineering lecturer from the Bandung Institute of Technology, said wastewater produced by textile factories can be harmful to the environment.
By law, companies must treat their wastes chemically using binding agents or biologically using bacteria, Roosmini explained. These processes will make the hazardous pollutants settle into a sludge, which must then be disposed of safely at a licenced disposal company.
The resulting water must meet certain standards before they can be dumped into bodies of water like the Citarum. That is the problem. The government has installed nets along the watercourse manned by hundreds of officials who pick up tonnes of trash each day. Trash also gets tangled on the water hyacinths floating on the river surface or washed ashore to the riverbanks.
The amount of trash can be so overwhelming that the entire surface of the watercourse is covered, forcing officials and labourers to work for hours just to clear the waste. The reason, activists and experts say, is that the 13 regencies and cities straddling along the Citarum have inadequate waste management systems. Bandung and its four surrounding regencies, for example, only has one landfill with a capacity of 2, tonnes per day.
The Bandung metropolitan area has a population of 8. Meanwhile, the Ministry of Environment and Forestry estimated that on average each person produces 0. As a result, all across the Greater Bandung area there are piles of rubbish left by the roadside next to packed trash bins waiting to be picked up by sanitation workers who come once every few days. Another common sight are empty plots of land being used as impromptu landfills or sites for open burning, which creates suffocating smoke.
The rest of the trash can be found littering open sewers, creeks and streams which flow into major rivers like the Citarum. Last month, during the United Nations Climate Change Conference in Glasgow, West Java Governor Ridwan Kamil presented how the province is home to a trash-for-cash scheme to collect and recycle plastic bottles and cups as part of the efforts to keep the Citarum clean.
West Java, the governor continued, also hosts several small businesses which turn multi-layer food and detergent packaging into floor mats and bags as well as maggot farms which eat away organic wastes. We will push all regencies to start sorting wastes and create a circular economy. Because today, the amount of waste which ends up in our landfills and incinerators is not decreasing.
Riswandani, the activist, agreed that getting people to recycle their wastes is the way to go, but he also called for more government intervention. The same goes for waste banks. But they are not supported by banks and financing firms.
