2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
The document does not explicitly state the specific number of units used for each test. However, it details "verification and validation activities" conducted on the "Mid-size Single Compartment Warming Cabinet". The nature of these tests (electrical, system functions, heating performance, mechanical tests) suggests that the testing was performed on the device itself (product prototypes or final units) rather than on a dataset of external data. This would be considered prospective testing of the device hardware and software. The country of origin of the data is not specified, but the manufacturer (STERIS Corporation) is based in Mentor, OH, USA, implying the testing was likely conducted in the US or by a contracted lab.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)
Not applicable. This is a medical device (warming cabinet) validation, not an AI or diagnostic imaging study. Ground truth in this context is established by engineering specifications, safety standards (UL, CAN/CSA), and performance requirements for heating and mechanical integrity. There are no "experts" in the clinical sense establishing ground truth; rather, the device's performance is measured against predefined objective physical and electrical standards.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
Not applicable. As described above, the acceptance criteria are objective physical and electrical measurements against established standards. There is no subjective interpretation or "adjudication" required in the typical sense of a clinical study or AI model evaluation.
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 is not an AI or diagnostic imaging device.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
Not applicable. This is not an AI or algorithm-based device in the context of diagnostic or interpretive functions. The "software" mentioned is for control and data recording within the device's operational functions, not for independent diagnostic output.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
The ground truth for this device's performance is based on:
- Engineering Specifications: Specific temperature ranges, electrical parameters, power draw.
- Safety Standards: Compliance with UL 61010-1 and CAN/CSA C22.2 61010-1 for electrical safety.
- Performance Requirements: Functional operation of fans, alarms, door locks, and heating profiles under various load conditions.
- Mechanical Integrity Standards: Resistance to physical stress (drop test, load test).
These are objective, measurable criteria, not subjective expert consensus or clinical outcomes data.
8. The sample size for the training set
Not applicable. This is not an AI or machine learning device that requires a training set. The device operates based on predefined engineering and control logic.
9. How the ground truth for the training set was established
Not applicable. As this is not an AI/ML device, there is no training set or associated ground truth for such a set.
§ 880.5725 Infusion pump.
(a)
Identification. An infusion pump is a device used in a health care facility to pump fluids into a patient in a controlled manner. The device may use a piston pump, a roller pump, or a peristaltic pump and may be powered electrically or mechanically. The device may also operate using a constant force to propel the fluid through a narrow tube which determines the flow rate. The device may include means to detect a fault condition, such as air in, or blockage of, the infusion line and to activate an alarm.(b)
Classification. Class II (performance standards).
