Device Description

The Fort Defiance Industries FRONT-LINE Field Sterilizers are autoclaves designed for sterilizing heat- and moisture-stable medical, dental, and surgical materials, including wrapped and unwrapped, solid, porous, and hollow items (e.g., dental handpieces, suction pipes) in healthcare facilities. The devices use electrical resistive heaters to produce steam as the sterilizing agent. The devices adhere to sterilization processes and requirements that are universally accepted sterilization standards for Tabletop Steam Sterilizers. A touchscreen controller is used for monitoring and control of the device.

The devices are equipped with multiple safety features. The door includes a safety locking mechanism and door switch. The door switch does not permit cycle operation unless the door is sealed closed and does not permit the door to be opened until the internal chamber pressure is at atmospheric pressure. Additional safety features include electronic overtemperature and overpressure protection, an independent high temperature cutoff switch, and a pressure safety relief valve for the pressure vessel.

Only United States Food and Drug Administration cleared sterilization accessories should be used with these autoclaves.

2. Sample size used for the test set and the data provenance

The document does not explicitly state a numerical sample size for the test set. However, a series of performance effectiveness tests were conducted for each cycle type (Immediate Use, Textiles, Wrapped Instruments/Pouches, Handpieces) across both FL120 and FL135 models. These tests were performed "by passing 3 successive cycles at half the programmed exposure time." This indicates that at least three runs were conducted for each sterilization cycle condition for both models.

The data provenance is from Fort Defiance Industries LLC itself, conducting validation studies in accordance with AAMI/ANSI ST55:2016. This suggests that the studies were internal, likely prospective laboratory testing. No information on country of origin of the data is provided beyond Fort Defiance Industries being a US company.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

Not applicable. The ground truth for this device is established through meeting the sterilizing performance criteria defined by the ANSI/AAMI ST55:2016 standard, specifically achieving a sterility assurance level (SAL) of at least 10^-6, and safety standards like IEC and ASME. This is a technical performance measurement rather than an expert interpretation of data.

4. Adjudication method for the test set

Not applicable. The evaluation is based on objective measurements and compliance with established performance standards for sterilization, rather than subjective interpretation requiring adjudication.

5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

Not applicable. This device is a medical sterilizer, not an AI-powered diagnostic or interpretive tool that would involve human readers or AI assistance.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

Yes, in concept, the performance testing described is "standalone" for the device, meaning the sterilizer's effectiveness is evaluated on its own based on its ability to sterilize according to predefined biological and physical parameters. There is no human-in-the-loop performance aspect for a sterilizer.

7. The type of ground truth used

The ground truth used for the performance effectiveness of the sterilizer cycles is based on:

  • Biological performance: Achieving a sterility assurance level (SAL) of at least 10^-6, demonstrated by the "overkill method" using biological indicators.
  • Physical and technical parameters: Compliance with predefined temperature accuracy, pressure measurement, air removal, moisture retention, software functionality, and electrical/safety standards as outlined in ANSI/AAMI ST55:2016, IEC 61010-1, IEC 61326-1, IEC 61010-2-040, and ASME Boiler and Pressure Vessel Code.

8. The sample size for the training set

Not applicable. This device is a medical sterilizer and does not involve machine learning or AI models that require a training set.

9. How the ground truth for the training set was established

Not applicable, as there is no training set for this device.

4. Design and Materials

The FRONT-LINE Field Sterilizers, models FL120 and FL135, are steam sterilizers composed of a stainless-steel chamber, an aluminum chamber door, electric resistive heaters, a plumbing system with a clean water tank, control system, and an aluminum frame providing a housing for all components. The devices are electronically controlled, and each device includes 10 pre-programmed sterilization cycles. All materials in the sterilization system and plumbing system are deemed acceptable for steam sterilizers.

న. Technology

The FRONT-LINE series of autoclaves are steam sterilizers composed of a pressure vessel that utilizes electric resistive heaters to produce the sterilizing agent, steam, from a chamber boiler. The autoclaves contain an electronic control system that automatically initiates programmed Steam Flush Pressure Pulse (SFPP) phases to purge atmospheric air from the chamber followed by a timed steam exposure and drying phase. Exhaust air purged during the dry phase passes through a heat exchanger to condense water vapor and reclaim as much condensate as possible for reuse.

7. Comparison of Technology

The previously cleared device and the FRONT-LINE Field Sterilizers FL120 and FL135 are traditional steam sterilizers of similar chamber size using AAMI approved Steam Flush Pressure Pulse (SFPP) dynamic air removal cycles. The previously cleared device and the FRONT-LINE series sterilizers use electric heaters to generate steam and touchscreen controllers for cycle control. Based on the information provided below, there are negligible differences noted between the FRONT-LINE series and the predicate with regards to chamber size, cycle parameters, and configuration of steam generation. The differences do not affect safety or effectiveness of the new devices compared to the predicate.

8. Summary of Non-Clinical Testing

Fort Defiance Industries conducted validation studies in accordance with AAMI/ANSI ST55:2016 (FDA Recognition Number 14-518). Design outputs and testing demonstrate that the FRONT-LINE Models FL120 and FL135 autoclaves meet all aspects of the standard.

Performance effectiveness of the sterilizer cycles and exposure time recommendations were demonstrated by the overkill method by passing 3 successive cycles at half the programmed exposure time to guarantee a sterility assurance level (SAL) of at least 10 to probability of survival. Fort Defiance Industries validates its sterilization cycles using recommended practices, standards and guidelines developed by independent organizations such as the Association for the Advancement of Medical Instrumentation (AAMI). The Fort Defiance Industries FRONT-LINE Field Sterilizers FL120 and FL135 have been validated to meet the requirements of ANSI/AAMI ST55:2016, Tabletop Steam Sterilizers (FDA Recognition Number 14-518). Table 2 summarizes FRONT-LINE Field Sterilizer FL120 and FL135 effectiveness testing and results performed by Fort Defiance Industries.
