Device Description

HAMILTON-H900

The HAMILTON-H900 respiratory gas humidifier is designed to add heat and moisture to respiratory gases, which are then administered to patients who need invasive or noninvasive ventilation. The breathing gas is passed through a humidifier chamber, where the gas is heated and humidified using an external heat source.

The HAMILTON-H900 humidifier uses breathing circuits that are recognized automatically when connected to the humidifier. The humidifier uses two heating systems as heat sources:

  • -A heating plate that has contact with the metal plate of a special humidifier chamber inserted into the base of the humidifier prior to application, thus heating the water contained inside the chamber.
  • -The controlled heating within the breathing circuits.

The respiratory gas exiting the humidifier chamber is continuously monitored using temperature sensors that are integrated into the humidifier base. Additionally, a temperature probe inside the breathing tube is used to measure the temperature of the gas delivered to the patient airway.

The design of the breathing tubes offers heating performance over the entire length by providing constant heating of the entire tube wall, from the chamber exit to the patient connection. A float mechanism, together with detection of the water level inside the humidifier chamber and the autofill mechanism, keeps a constant water level.

HAMILTON-BC8010

The HAMILTON-BC8010 is a single-use, dual-limb breathing circuit comprising heated inspiratory and heated expiratory tubes. The humidifier chamber uses a float mechanism to keep a constant water level inside the auto-feed chamber.

HAMILTON-BC4010

The HAMILTON-BC4010 is a single-imb breathing circuit comprising a heated inspiratory tube. The humidifier chamber uses a float mechanism to keep a constant water level inside the auto-feed chamber.

HAMILTON-HC322/HC310

The HAMILTON-HC322/HC310 are single-use humidifier chambers with a float mechanism to keep a constant water level inside the auto-feed chamber. The HAMILTON-HC322 humidifier chamber is part of the HAMILTON-BC8022/BC4022 breathing sets and the HAMILTON-HC310 humidifier chamber is part of the HAMILTON-BC8010/BC4010 breathing sets, as cleared in K152029.

AI/ML Overview

This is a 510(k) summary for a medical device (respiratory gas humidifier and breathing circuits), not an AI/ML medical device. Therefore, the information requested about acceptance criteria, study details, and ground truth establishment, which are typical for AI/ML device submissions, are not primarily available or applicable in the provided text.

The document discusses substantial equivalence to predicate devices based on technological characteristics and performance, focusing on non-clinical data. It does not describe an AI/ML algorithm that predicts or diagnoses based on medical images or other data, nor does it detail a study that evaluates the performance of such an algorithm against a ground truth established by experts.

However, I can provide the acceptance criteria and performance as described for this specific device, based on the provided text, recognizing that it's not in the context of an AI/ML model.

Here's an analysis of the provided text, focusing on the closest equivalents to your requested information, understanding the context is a medical device, not an AI/ML diagnostic:


The provided text is a 510(k) summary for the Hamilton-H900 Humidifier and Hamilton-BC series breathing circuits. This document outlines the rationale for the device's substantial equivalence to previously cleared predicate devices. The "acceptance criteria" and "study that proves the device meets the acceptance criteria" in this context refer to engineering and performance specifications and non-clinical testing, rather than the type of clinical performance study typically conducted for AI/ML diagnostic or predictive devices.

Therefore, many of the requested points (e.g., number of experts for ground truth, adjudication methods, MRMC study, standalone performance for an algorithm) are not applicable to this type of device submission.

Here is the information extractable from the document, focusing on performance characteristics and non-clinical testing rather than AI/ML specific criteria:

Acceptance Criteria and Reported Device Performance (Non-AI/ML Context)

The acceptance criteria are implied by the "Characteristic used for comparison" and the "HAMILTON-H900 (Subject device)" column in Table 1 for the humidifier and Table 2 for the breathing circuits. The "reported device performance" is the statement that the subject device meets these established characteristics, which are largely identical to the predicate device.

2. Sample Size Used for the Test Set and Data Provenance

As this is a medical device submission based on substantial equivalence and non-clinical testing rather than an AI/ML study with a "test set" of patient data, specific "sample sizes" in the sense of clinical cohorts are not detailed. The testing involved:

  • Electrical Safety and Electromagnetic Compatibility: Conducted on the HAMILTON-H900 and HAMILTON-BC-series breathing circuits.
  • Mechanical Testing: Conducted on the HAMILTON-H900 and HAMILTON-BC-series breathing circuits.
  • Software Verification and Validation Testing: Conducted for the software within the HAMILTON-H900.
  • Biocompatibility Testing: Performed on "relevant parts of the breathing circuit."
  • Human Factors / Usability Study: Conducted on the HAMILTON-H900.

The document does not specify the number of units tested for each category, which is typical for non-clinical testing reports summarized in 510(k)s.

Data Provenance: The document does not specify the country of origin of the data or explicitly state whether the tests were retrospective or prospective. Given these are physical device tests, they would be prospective (performed specifically for this submission). The applicant is based in Switzerland (Hamilton Medical AG, Via Crusch 8, 7402 Bonaduz, Switzerland).

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications

Not applicable. "Ground truth" in the context of an AI/ML algorithm with expert adjudication is not relevant here. The "ground truth" for this device's performance is objective measurements against engineering specifications and international standards (e.g., temperature accuracy, flow resistance, humidity output).

4. Adjudication Method for the Test Set

Not applicable. There is no expert adjudication for this type of device testing. Performance is measured against predefined engineering and safety standards.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done

No. An MRMC study is for evaluating human reader performance, often with and without AI assistance, typically in diagnostic imaging. This device is a respiratory gas humidifier and breathing circuit, not a diagnostic AI/ML system.

6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done

Not applicable directly. This device is a physical medical device, not a standalone algorithm. Its performance is evaluated against its physical and electronic specifications.

7. The Type of Ground Truth Used

The "ground truth" for this device's performance is established by engineering specifications, adherence to international standards (e.g., IEC 60601 series, ISO 8185, ISO 5367, ISO 5356-1, ISO 10993 series), and objective measurements during non-clinical testing. For example, temperature accuracy is measured against a calibrated standard, not against a human expert's assessment.

8. The Sample Size for the Training Set

Not applicable. This is not an AI/ML device that requires a training set.

9. How the Ground Truth for the Training Set Was Established

Not applicable. This is not an AI/ML device that requires a training set with established ground truth.
