No
The document describes a chemical disinfectant system and its efficacy testing, with no mention of AI or ML technologies.

No
The device is a high-level disinfectant system intended for processing heat-sensitive medical devices, not for therapeutic purposes.

No

Explanation: The device is described as a high-level disinfectant system intended for processing heat-sensitive medical devices, not for diagnosing medical conditions.

No

The device description clearly states it is an "apparatus that produces a single use High Level Disinfectant by on-site electrochemical activation (electrolysis)". This describes a physical hardware system, not software.

Based on the provided text, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use is for "processing heat sensitive medical devices" as a "high level disinfectant system." This describes a process for cleaning and disinfecting medical equipment, not for diagnosing a condition or analyzing a sample from the human body.
  • Device Description: The description details a system that produces a disinfectant solution for use on "re-usable heat-sensitive medical devices." This reinforces its purpose as a disinfectant for medical instruments.
  • Lack of IVD Characteristics: The text does not mention any of the typical characteristics of an IVD, such as:
    • Analyzing biological samples (blood, urine, tissue, etc.)
    • Providing diagnostic information about a patient's health
    • Measuring analytes or biomarkers
    • Being used in a laboratory setting for diagnostic purposes

The device is clearly intended for the disinfection of medical devices, which falls under the category of medical device reprocessing, not in vitro diagnostics.

Residue testing was performed to quantify any residuals remaining after disinfection with Sterilox above MRC and rinsing according to the label claims. The endoscope was then extracted and the eluates analyzed for residual Sterilox components. The results showed that Sterilox germicide well above its maximum use concentration is effectively removed from a complex device such as a flexible endoscope by the rinse cycle after disinfection and therefore poses no additional risk to the patient or user of the device.

Toxicological Evaluation of Sterilox:
Skin Irritation (Rabbits): Non-irritating
Skin Sensitization (Guinea Pig): Non-sensitizing
Acute Dermal Toxicity (Rabbits): Dermal LD50 > 2 g/kg body weight
Acute Oral Toxicity (Rats): Dermal LD50 > 5 g/kg body weight
Primary Eye Irritation (Rabbits): Non-irritating
Bacterial Mutation Assay: Non-mutagenic
Cytotoxicity: Non-cytotoxic

Patient toxicity:
Skin irritation and skin sensitization maximization test have been conducted. There were no indications of irritation or sensitization.

User toxicity:
An acute oral toxicity test (by the OECD 'fixed dose' procedure), a primary eye irritancy study and a bacterial mutagenicity study in Salmonella typhimurium (the 'Ames' test) have been conducted. Results indicated that Sterilox germicide is non-mutagenic and non-irritating to the eye.

Materials Compatibility:
The material compatibility was evaluated by subjecting a variety of metallic, plastic, adhesive and rubber endoscope components to continuous immersion in Sterilox. Sterilox germicide does not produce any corrosion or other visible damage in the majority of endoscope components. Color changes and the "tack" of the coating of the outer endoscope sheaths were noted on some endoscopes. Corrosion was noted on anodized aluminum.

1.12 Residue Data:

Residue testing was performed to quantify any residuals remaining after disinfection with Sterilox above MRC and rinsing according to the label claims. The endoscope was then extracted and the eluates analyzed for residual Sterilox components. The results showed that Sterilox germicide well above its maximum use concentration is effectively removed from a complex device such as a flexible endoscope by the rinse cycle after disinfection and therefore poses no additional risk to the patient or user of the device.

1.13 Toxicological Evaluation of Sterilox:

Testing was performed to determine the potential toxicological effects of exposure to Sterilox liquid chemical High Level Disinfectant. The results are summarized as follows:

Skin Irritation (Rabbits)Non-irritating
Skin Sensitization (Guinea Pig)Non-sensitizing
Acute Dermal Toxicity (Rabbits)Dermal LD50 > 2 g/kg body weight
Acute Oral Toxicity (Rats)Dermal LD50 > 5 g/kg body weight
Primary Eye Irritation (Rabbits)Non-irritating
Bacterial Mutation AssayNon-mutagenic
CytotoxicityNon-cytotoxic

In section III.I.3 'Evaluation of toxicity' of the quidance for industry and FDA reviewers indicates the tests that should be considered when evaluation the biocompatibility of the germicidal product or the individual ingredients.

1.14 Patient toxicity:

Skin irritation and skin sensitization maximization test have been conducted on the product, Sterilox germicide. The test reports indicate that the studies were conducted properly. There were no indications of irritation or sensitization. Although positive results of studies on cytotoxicity and on haemocompatibility might be predicted from knowledge of the effects of hypotonic aqueous solutions generally, these results would also be expected of any suitably disinfected water used to rinse equipment.

As the toxicity of the product is essentially similar to that of chlorine based disinfectants, it is unlikely that any useful information will be obtained from further studies and it is therefore undesirable on the grounds of animal welfare to conduct these studies.

1.15 User toxicity:

An acute oral toxicity test (by the OECD 'fixed dose' procedure), a primary eye

irritancy study and a bacterial mutagenicity study in Salmonella typhimurium (the 'Ames' test) have been conducted on the product, Sterilox germicide. The test reports indicate that the studies were conducted properly. The results of these tests indicated that Sterilox qermicide is non-mutagenic and non-irritating to the eye.

As, for toxicological purposes, the product is essentially equivalent to chlorine disinfectant, the conclusion reached by the International Program on Chemical Safety in Environmental Health Criteria 216 (2000) concerning the toxic effects of these disinfectants in drinking water that:

"Evidence from animal and human studies suggests that exposure to chlorine, chlorite solutions, chloramine and chlorine dioxide themselves probably do not contribute to the development of cancer or any toxic effects".

This also applies to the Sterilox germicide solution, thus undertaking additional testing is scientifically unnecessary and, on animal welfare grounds the studies should be omitted.

1.16 Toxicological Conclusion:

For all practical purposes the health risks to patient and to operator arising from exposure to Sterilox germicide and diluted Sterilox germicide are minimal. The principal potential effect of the chemicals present in Sterilox would be irritation, but Sterilox does not exhibit this effect in tests. Sterilox is unlikely to pose a significant risk to either patient or user.

1.17 Materials Compatibility:

The material compatibility of the Sterilox germicide was evaluated by subjecting a variety of metallic, plastic, adhesive and rubber endoscope components to continuous immersion in Sterilox. The samples were inspected for, visible change, visible evidence of damage or any other change in appearance. Sterilox germicide does not produce any corrosion or other visible damage in the majority of endoscope components. Color changes and the "tack" of the coating of the outer endoscope sheaths were noted on some endoscopes. Corrosion was noted on anodized aluminum.

1.18 Assessment of non-clinical performance data for equivalence:

The Sterilox High Level Disinfectant System complies with:

The Essential Requirements of Annex I of the Medical Device Directive 93/42/EEC and is manufactured under a Quality System approved by LRQA (Notified Body No. 0088) complying with Annex VII & V of the Directive.
