The Giraffe Incubator Carestation is an Infant Incubators provide heat in a controlled manner to neonates who are unable to thermo-regulate based on their own physiology. They achieve this by providing an enclosed temperature controlled environment to the infant. This device may incorporate a Servo Controlled Oxygen Delivery System. This is indicated to provide a stable oxygen concentration within the infant compartment at the value set by the operator (21-65%).

The Giraffe OmniBed Carestation is a combination of an infant incubator and an infant warmer. The device can be operated as an incubator or as a warmer and can transition from one mode to the other on user's demand. It cannot be operated in both modes at the same time. Incubators and warmers provide heat in a controlled manner to neonates who are unable to thermo- regulate based on their own physiology. Incubators provide an enclosed, temperature-controlled environment and warmers provide infrared heat in an open environment. They may also be used for short periods of time to facilitate the neonate's transition from the uterus to the external environment. This device may incorporate a Servo Controlled Oxygen Delivery System. This is indicated to provide stable oxygen concentration within the infant compartment at the value set by the operator (21-65%).

The Giraffe OmniBed Carestation is a device that can function as an incubator (in the closed mode) or as an infant radiant warmer (in the open mode) based on the user's selection.

Incubators and warmers provide heat in a controlled manner to neonates who are unable to thermo-regulate based on their own physiology.

In the closed bed mode of operation, the bed functions as an incubator, maintaining the infant's temperature by circulating heated air within the enclosed bed compartment. Warm air is circulated through the closed patient compartment. The operator may select either the air or skin temperature control method. Depending on the control method selected, heat is regulated based on either the air temperature or the infant's skin temperature compared to the operated selected control temperature. Physical access to the patient is obtained through the side portholes or by opening one of the side doors.

In the open bed mode, this bed operates like a conventional open, radiantly heated infant bed. Radiant heat from an infrared heat source is focused onto the bed to warm the patient. The Giraffe OmniBed Carestation incorporates an optional weighing scale, Servo O2, Uninterruptible Power Supply (UPS) & Shuttle, Mounting Accessories Rail and Shelves and Storage drawers.

This document is a 510(k) premarket notification for the "Giraffe Incubator Carestation CS1" (K213553). The submission seeks to demonstrate substantial equivalence to a legally marketed predicate device, the "Giraffe Omnibed Carestation CS1" (K152814), specifically concerning modifications to porthole and wall latches.

Detailed Information for the Study:

2. Sample size used for the test set and the data provenance:

• Test Set Sample Size: Not explicitly stated for each individual bench or reliability test. The tests were performed on the "modified wall and porthole latches," implying testing on the physical components of the device. For the Summative Usability Study, the sample size of users is not provided in this document.
• Data Provenance: The studies are laboratory and human factors evaluations conducted by the manufacturer (GE Healthcare). The data is presumably retrospective in nature, as it's part of the design verification and validation process for a modified existing product. Country of origin for the data is not specified but would be where GE Healthcare conducts its product testing.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

• This information is not provided in the document. For bench/reliability tests, "experts" typically refers to test engineers and quality control personnel, whose qualifications are inherent to their roles in device manufacturing and verification. For the human factors study, the qualifications of the "users" involved are not detailed.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set:

• Not applicable in the context of engineering bench and reliability testing or human factors usability studies as described. These are objective tests against predefined specifications or assessments of user interaction, not expert consensus for diagnostic interpretation.

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-assisted diagnostic device, and no MRMC study was conducted. The device is a neonatal incubator/warmer; the changes are mechanical (latches) and do not involve "human readers" or "AI assistance."

6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done:

• Not applicable. This device is not an algorithm, and its performance involves direct physical interaction and function.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):

• Ground truth for the engineering tests was based on objective performance specifications derived from international standards (IEC 60601 series) and internal quality system requirements. For example, "Temp Control accuracy: ± 1.0ºC" is an objective metric.
• For the Human Factors Analysis, the ground truth was the observed user interaction and direct feedback regarding the usability and safety of the modified latches. The absence of findings that required design changes indicates that the user experience met safety and usability requirements.

8. The sample size for the training set:

• Not applicable. This device does not use machine learning or AI models, so there is no "training set."

9. How the ground truth for the training set was established:

• Not applicable for the same reason as above.
