Overview

NCA scientists created and developed the new Bowie Dick Test Indicator as a way to tackle the challenges posed by the growing uncertainty in sterility assurance for dental & medical instruments, and to ensure complete functionality of autoclaves/sterilizers. We were able to differentiate our indicators by allowing the entire sterilization cycle to be monitored from start to finish. Each cycle in a sterilizer undergoes several cycle types, such as pressure, vacuum, steam injection, time and temperature. Each one of these parameters must be measured as the cycle progresses. Therefore, if you stop the cycle half-way and pull out our indicator, you will see that only half of the indicator passed (unlike other tests that pass in the beginning of the cycle, giving you a false pass (false positive)). This makes NCA indicators 100% efficient in the monitoring process, giving you more precise and absolute scientific results for your infection control.

NCA products have been tested internationally by NQA testing laboratories, the highest level of quality assurance testing in the world for scientific products. They hold a Certificate of Conformity and are approved by the Australian Therapeutic Goods Administration (TGA) (the equivalent of the FDA in the U.S.).

 

The NCA Bowie Dick indicators are universal and can be placed into most Process Challenge Devices (PCD’s), or helix devices, to provide assurance of the sterility process. They measure all parameters critical to the sterility process and have an affixed sticker on the rear of each indicator, enabling them to be placed intuitively into the daily run sheet to log results for more effective tracking of your autoclave’s health & functionality.

Proprietary Technologies

NCA Quattro Detection Technology

According to ISO standards referenced in AAMI standards, the only way to scientifically prove and validate sterility of instruments is to detect all the four parameters:

1- Temperature

2- Time

3- Steam & Pressure

4- Air Removal

Surprisingly, in the U.S. market, the only available sterilization validation indicators whether it was strips, pouches or biological spores vials don’t monitor all the required parameters, especially the critical air particles or Non Condensable Gases (NCG’s) which contain spore populations, which in turn, contains viruses. 

As a way to tackle the challenges posed by the growing uncertainty in sterility assurance for dental & medical instruments, NCA scientists developed an innovative formulation with a sophisticated technology to allow a strip indicator to detect all the 4 parameters to fully comply with sterilization standards and confirming to best practice, protecting both the practice from liability and the patient and staff from infection.

To reduce contamination and infections and reduce the times wasted to re-disinfecting surfaces over and over again wasting precious staff times and disinfection material the R4+ formula is equipped with the new Advanced Barrier Shield technology that was developed by NCA that gives it a long lasting effect and keeps the disinfectant working on the surface for up to 4 hours even after it dries off. It also protects surfaces and lengthens its life as the barrier technology creates a shield that prevents corrosion and prevents liquids and germs from seeping through into its pours which protects it from contamination (i.e. fabric, leather seams, etc).

The “R4” stands for the four quats compounds that were used and the “+” stands for the addeditives and added technologies and features.

High Accuracy NCG’s Detection

This technology allows the strip indicator to detect volumes of air (non-condensable gases) down to less than 1 ml, which is the volume required to harvest a spore inside a lumen (hollow/cannulated instruments). Those spore sized air and non-condensable gases “NCG’s” pockets, will allow dangerous pathogens to exist.

Some autoclaves/sterilizers have a built-in monitoring system. The built-in monitoring systems for sterilizers/autoclaves are not meant for monitoring instruments, but they only monitor  the sterilizer itself. This means that it monitors to a porous level which requires 150ml of air remaining in the chamber to pass. Only NCA Bowie Dick indicators and the NCA Process Validation Challenge Device (PCD) can detect less than 1ml of air which is what’s required to provide evidence of sterility assurance inside handpieces and other lumens and hollow/cannulated instruments.

NCA End-Point Detection Technology

NCA End-Point Detection Technology is an innovative technology which allows for continuous detection of sterilization parameters throughout the Full autoclave’s cycle. Unlike any other indicator which passes halfway through giving a false pass result. 

This makes the NCA Bowie Dick indicators the most accurate in the market providing the highest level of sterilization assurance and scientific evidence to protect patients, staff from infection and practice from liability.

Features

  • Most Accurate & Reliable Result: State of the art challenge indicators – completely different from any other indicators currently on the market
  • Monitors All Critical Parameters: The critical parameters required for sterilization assurance are pressure, air vacuum, steam injection, time and temperature. This device monitors all parameters throughout the whole cycle, ensuring complete functionality of your autoclave/sterilizer.
  • High Accuracy Detection – to even the last spore sized air and non-condensable gas pockets (1  ml), which allows dangerous pathogens to exist.
  • The One and Only Start-To-Finish Monitoring: Unlike other Bowie Dick Test products, this is the only product that monitors the autoclave sterilization cycle from start-to-finish.   Others do not meet the “end point” and hence pass within the first half of the cycle, giving a false and unreliable result.
  • Fully Conforms To Highest Standards: ANSI/AAMI/ASTM/ISO 11140-1 & ISO 17665-1
  • Universal: Can be used in most Process Challenge Devices (PCD’s), Test Packs, or Helix devices.
  • Evidence Record Keeping: Includes affixed sticker to place inside daily log-sheet and validation reports as evidence of sterility assurance.
  • Reusable and Easily Accessible Slide Box: User-friendly box to retrieve test strips
  • Tested and certified by independent laboratories: Certified by NQA Global Certification Body – the highest level of Quality Assurance testing in the world for scientific products.
  • Replaces Helix Test and standard Bowie Dick Test in B Class Bench-top Autoclaves.
  • TGA Approved: Tested and approved by the Australian Department of Health Therapeutic Goods Administration.
  • Certificate of Conformity.
