The document describes software modifications for compatibility with sensors and speaking valves, and the addition of a continuous flow feature. There is no mention of AI or ML in the intended use, device description, or performance studies. The "Adaptive Support Ventilation (ASV)" mentioned is a ventilation mode, not necessarily indicative of AI/ML in this context without further detail.
Yes
The device is a ventilator that provides ventilatory support, which is a therapeutic intervention for patients requiring assistance with breathing.
No
The device is a ventilator, which provides respiratory support, not a diagnostic assessment.
No
The device description clearly states that the HAMILTON-C1 and HAMILTON-T1 are ventilators, which are hardware devices. The submission describes software modifications and new features added to these existing hardware ventilators.
Based on the provided text, the HAMILTON-C1 and HAMILTON-T1 ventilators are not IVD (In Vitro Diagnostic) devices.
Here's why:
- IVD devices are used to examine specimens derived from the human body (like blood, urine, or tissue) to provide information for diagnosis, monitoring, or screening.
- The description of the HAMILTON-C1 and HAMILTON-T1 clearly states their intended use is to provide positive pressure ventilatory support or continuous flow of respiratory gases directly to patients. They are supporting a physiological function, not analyzing biological samples.
The text focuses on the mechanical and software functions of the ventilators and their compatibility with sensors and speaking valves, all of which relate to direct patient care and respiratory support, not in vitro analysis.

Device Description
The HAMILTON-C1 and HAMILTON-T1 ventilators are designed for adults, pediatrics, infants and neonatal patients requiring invasive or non-invasive ventilation support. All ventilators cover a range of clinical requirements, including invasive ventilation, automated ventilation with Adaptive Support Ventilation (ASV), and Non-Invasive Ventilation.
The previously cleared ventilators, HAMILTON-C1 and HAMILTON-T1 (both K140939), have been bundled together in this 510(k) submission in order to add the following new features:
- A modification to the software allows compatibility with the Nihon Kohden -SpO2 sensors to be used with HAMIILTON-C1 and HAMILTON-T1 ventilators. These ventilators are already compatible and cleared for use with Masimo SpO2 sensors (K140939).
- cFlow was added, which continuously delivers an air/gas mixture.
- A modification to the software, which allows HAMILTON-C1/T1 ventilators to be compatible for use with speaking valves. A speaking valve allows tracheostomized adult and pediatric patients to communicate verbally.

Description of the test set, sample size, data source, and annotation protocol
Nonclinical performance tests including Software Design and Validation process, and bench testing were conducted. Testing demonstrated compliance with various guidelines and standards (listed in Non-Clinical Performance Tests). Additional software verification and validation testing followed FDA guidance for "major" level of concern software. Comparison testing was completed for the new features (cFlow, Speaking Valve, and Nihon Kohden SpO2 sensors) against legally marketed devices, including waveform comparison for the Speaking Valve Feature.
Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The Software Design and Validation process, together with the bench testing of the device, demonstrated that the HAMILTON-C1/T1 operates as intended.
Testing of the modified HAMILTON-C1/T1, with the new features, was conducted. The new features cFlow, Speaking Valve, and the use of Nihon Kohden SpO2 sensors were subjected to comparison testing with legally marketed devices. Furthermore, waveform comparison testing was completed for the Speaking Valve Feature. The data provided from these tests was shown to be equivalent to the legally marketed devices.

VIII. COMPARISON OF TECHNOLOGY CHARACTERISTICS WITH THE REFERENCE DEVICES
The Nihon Kohden NKV-550 Series Ventilator System is used as a reference device for the proposed HAMILTON-C1/T1 as both the reference device and the proposed device are intensive care ventilators which have the O2 therapy/cFlow feature.
The HAMILTON-C3 is used as a reference device for the proposed HAMILTON-C1/T1 as both the reference device and the proposed device are intensive care ventilators which can be used with Nihon Kohden SpO2 sensors and accessories.
The Esprit Ventilator V200 with Speaking mode Option is used as a reference device for the proposed Speaking valve compatibility on the modified HAMILTON-C1/T1, which is only available in invasive modes for tracheostomized patients with the use of a special speaking valve, for example the Passy-Muir valve.
IX. NON-CLINICAL PERFORMANCE TESTS
The following performance and nonclinical data are provided in support of the substantial equivalence determination.
The Software Design and Validation process, together with the bench testing of the device, demonstrated that the HAMILTON-C1/T1 operates as intended.

AIM 7351731: Medical Electrical Equipment and System Electromagnetic Immunity Test for Exosure to Radio Frequency Identification Readers
Additional software verification and validation testing were completed as recommended by the FDA's "Guidance for Industry and FDA Staff: Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices." The software for this device was considered as a "major" level of concern, since a failure or latent flaw in the software could directly result in serious injury or death to the patient or operator.
Testing of the modified HAMILTON-C1/T1, with the new features, was conducted. The new features cFlow, Speaking Valve, and the use of Nihon Kohden SpO2 sensors were subjected to comparison testing with legally marketed devices. Furthermore, waveform comparison testing was completed for the Speaking Valve Feature. The data provided from these tests was shown to be equivalent to the legally marketed devices.
Since only materials already used in in the predicate (cleared under document number K140939) are described with this 510(k), Hamilton Medical did not conduct any additional biocompatibility testing.
X. CONCLUSION
The results of verification, validation, and testing activities demonstrate that the modified HAMILTON-C1 and HAMILTON-T1 ventilators are substantially equivalent to the legally marketed devices identified herein.
