The HAMILTON-C2 ventilator is intended to provide positive pressure ventilatory support to adults and paediatrics.
Intended areas of use:
• In the intensive care ward or in the recovery room.
• During transfer of ventilated patients within the hospital.
The HAMILTON-C2 ventilator is a restricted medical device intended for use by qualified, trained personnel under the direction of a physician and within the limits of its stated technical specifications.
The HAMILTON-C2 is an electronically controlled pneumatic intensive care ventilator. Due to its compact design, a weight of only 9,5 kg, built-in, hot-swappable batteries, and an ultra-quiet turbine, this ventilator can accompany a patient everywhere within a hospital, independently of central gas and power supplies.
The device offers ventilation modes that provide full and partial ventilatory support. The ventilator's ergonomic design, including a 10.4 in. color touch screen, a press-and-turn knob, and keys, let the user access the ventilator settings and monitored parameters. The graphical user interface can be tilt up to 45°. The HAMILTON-C2 can be customized so that it starts up with institution-defined settings.
Here's an analysis of the provided text regarding the HAMILTON-C2 ventilator, focusing on acceptance criteria and supporting studies:
It is important to note that the provided 510(k) summary for the HAMILTON-C2 ventilator (K090468) describes non-clinical performance tests and does not include information about clinical studies, MRMC studies, or specific AI/algorithm performance criteria. This device is a continuous ventilator, which generally undergoes extensive engineering and safety testing rather than clinical performance studies in the same way an AI diagnostic tool would.
Here's a breakdown based on your requested information:
1. Table of Acceptance Criteria and Reported Device Performance
| Acceptance Criteria (Implied) | Reported Device Performance |
|---|---|
| Safety: Device meets applicable safety standards. | "Safety testing of the HAMILTON-C2 was conducted according to IEC60601-1, IEC60601-1-2, IEC 60601-2-12 and other applicable standards. The test results show that the device is safe and effective for its intended use." |
| Effectiveness: Device is effective for its intended use. | "The test results show that the device is safe and effective for its intended use." |
| Performance (Waveform): Substantially equivalent to legally marketed devices. | "The ventilator was further subject to wave-form performance testing as described in the standard ASTM F1100-90. The data provided from these tests, were shown to be substantially equivalent to a legally marketed device [presumably the predicate devices: HAMILTON-G5 (K081521) and Dräger SAVINA (K023289)]." |
| Software Functionality: All specified requirements are correctly and completely implemented. | "The results of the software verification and validation testing demonstrate that all specified requirements have been implemented correctly and completely." |
| Substantial Equivalence: To predicate devices in indications, technological characteristics, and performance. | "The indication statements for the HAMILTON-C2 ventilator are comparable to those for the predicate devices. Technological characteristics and performance specifications of the HAMILTON-C2 ventilator are substantially equivalent to those of the predicate devices." |
2. Sample Size Used for the Test Set and Data Provenance
This information is not provided in the given 510(k) summary. The testing described focuses on engineering and safety standards (IEC, ASTM) rather than clinical data sets. Therefore, concepts like a "test set" in the context of clinical data are not applicable here.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications
This information is not provided and is not applicable to the type of testing described (engineering, safety, and performance standards for a ventilator). Ground truth based on expert consensus is typically relevant for diagnostic devices or AI algorithms that interpret medical images or data.
4. Adjudication Method for the Test Set
This information is not provided and is not applicable for the reasons stated above.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done, and Effect Size
No, a Multi-Reader Multi-Case (MRMC) comparative effectiveness study was not done. This type of study is typically performed for diagnostic devices, especially those incorporating AI, where the performance of human readers with and without AI assistance is evaluated. The HAMILTON-C2 is a ventilator, a life-support device, and its evaluation focuses on its technical safety and performance, not on human interpretation or diagnostic accuracy.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done
This is not explicitly stated in a manner relevant to AI algorithms. The HAMILTON-C2 is an electronically controlled ventilator, and its "performance" is inherently "standalone" in how it delivers ventilation based on its internal programming and user settings. The software verification and validation ensure its internal logic performs as designed, which is analogous to "standalone" performance for its specific function. However, it's not an AI algorithm acting independently in a diagnostic capacity.
7. The Type of Ground Truth Used
The "ground truth" for the HAMILTON-C2 ventilator's performance is established by:
- Engineering Standards: Adherence to international and industry standards like IEC60601-1, IEC60601-1-2, IEC 60601-2-12 for safety and ASTM F1100-90 for waveform performance.
- Predicate Device Performance: The functional performance, especially related to waveform, is compared against legally marketed predicate devices to demonstrate substantial equivalence.
- Software Specifications: The software's "ground truth" is its design specifications, validated through verification and validation testing.
8. The Sample Size for the Training Set
This information is not provided and is not applicable. The device is not described as involving machine learning or AI that would require a "training set" of data in the typical sense.
9. How the Ground Truth for the Training Set Was Established
This information is not provided and is not applicable, as there is no mention of a training set for machine learning or AI.
