No
The summary explicitly states "Not Applicable (No AI/ML component)" for sections related to training/test sets and performance metrics typically associated with AI/ML. The device description focuses on hardware components and basic features like a timer and temperature warning, not complex algorithmic processing.
Yes
The device provides phototherapy for the treatment of neonatal hyperbilirubinemia, which is a medical condition, making it a therapeutic device.
No
The device description clearly states its purpose is "phototherapy for the treatment of neonatal hyperbilirubinemia," and its principle of operation is "phototherapy using blue light to break down bilirubin." It is a treatment device, not one for diagnosis.
No
The device description explicitly details hardware components such as an assembled hut (shell with light source, base mattress, base), nest components, power supply, LED light array, and various materials (fabric-based, plastic, metal, electronic components).
Based on the provided information, the bili-hut™ is not an IVD (In Vitro Diagnostic) device.
Here's why:
- Intended Use: The intended use is to provide phototherapy for the treatment of neonatal hyperbilirubinemia. This is a therapeutic function, not a diagnostic one. IVD devices are used to examine specimens derived from the human body to provide information for diagnosis, monitoring, or screening.
- Device Description: The description details a phototherapy device that uses blue light to break down bilirubin. This is a physical treatment mechanism, not a method for analyzing biological samples.
- Lack of Diagnostic Elements: There is no mention of the device analyzing blood, urine, or any other biological sample. It does not provide diagnostic information about the patient's condition.
- Performance Studies: The performance studies focus on safety, electrical conformance, and bench performance related to light output and device function, not on diagnostic accuracy metrics like sensitivity or specificity.
The bili-hut™ is a therapeutic medical device used to treat a condition, not to diagnose it.

Device Description
The bili-hut™ is a modular, portable blue LED-based phototherapy device intended to treat neonatal hyperbilirubinemia, commonly known as infant jaundice.
The expected duration of treatment with the bili-hut™ is 48-72 hours, including interruptions for feeding, changing diapers and routine infant care as needed. The duration and method of treatment for each patient is decided by the prescribing clinician based on the baby's bilirubin levels and any other relevant medical history.
The bili-hut™ is used in the clinical or home setting.
Components and Optional Accessory: The bili-hut™ consists of the following components:
-
- Assembled hut
- a. Shell (includes the light source blue LEDs)
- b. Base mattress
- c. Base
-
- Nest components
- a. Nest
- b. Nest liner (intended patient contact)
- c. Nest mattress
- d. Nest mattress cover (intended patient contact)
-
- Power supply
The bili-hut™ has an optional accessory, the perch, which is a bassinet stand insert providing a treatment surface for the device in the hospital setting with the use of a hospital grade bassinet stand.
Features: The bili-hut™ features a timer which tracks the total use of the blue LED treatment lights in hours. The timer does NOT track individual patient treatment times. The device also has an Environment High Temperature Warning (EHTW) which is triggered at 43°C (109.4°F) when the bili-hut™ is placed in extremely high environmental temperature conditions. This feature turns off the blue treatment lights and alerts the user with a yellow indicator light on top of the shell.
Principle of Operation: Phototherapy is the principle of operation for the bili-hut™; the neonate is treated with blue light to decrease bilirubin blood levels by breaking down the bilirubin so it can pass out of the neonate's body. The bili-hut™ has one mode of operation; it is selected by the user with the on/off switch. The device is powered by a 12 V medical grade power supply and utilizes an LED light array to deliver therapeutic treatment. The average irradiance exceeds the American Academy of Pediatrics (AAP) standards for high intensity phototherapy; an irradiance greater than 30 microW/cm²/nm. Similarly, the bili-hut™ output average peak wavelength is consistent with the AAP standard wavelength 430-490 nm. Neither the output intensity nor the output wavelength are adjustable for the billi-hut™. Like other neonatal phototherapy devices, the blue phototherapy light from the bili-hut™ converts the yellow bilirubin pigment into a form that can naturally pass through the body, thus lowering the level of bilirubin in the infant's body.
Materials: The bili-hut™ is comprised of fabric-based, plastic, metal and electronic materials. Fabric materials include nylon, vinyl, polyester, cotton, polyethylene foam, hook & loop (Velcro) and polypropylene nonwovens. Plastic materials include polycarbonate, thermal polyurethane, nylon resin, high density polyethylene (HDPE) and styrene-butadiene rubber (SBR). Metal materials include aluminum, metalized polyethylene terephthalate (PET), zinc-plated steel and nickel. Electronic materials include components from printed circuit boards (PCBs), light emitting diodes (LED) and the power supply. The intended patient contact bili-hut™ components (disposable nest cover and disposable nest mattress liner) are comprised of polypropylene nonwovens, which are expected to be in contact with the patient throughout the duration of treatment (decided upon the prescribing clinician's discretion, usually 48-72 hrs).
The bili-hut™ is not to be used to treat a patient who is in an incubator or under a radiant warmer because it was not designed to be used with these two types of medical devices. Furthermore, Little Sparrows Technologies recommends that the bili-hut™ be used for patients with a birthweight of more than 2500 grams (5.5 pounds) and with a gestational age of greater than or equal to 35 weeks. However, the prescribing clinician defines the need for phototherapy with each patient.
Performance Specifications: The following are key performance specifications and features of the bili-hut™:
- Power supply
- Output peak wavelength:463 nm .
- . Average irradiance: 45 microW/cm²/nm
- Effective treatment area: 170 in2 (1097 cm²) ●
- Peak irradiance: 58 microW/cm²/nm ●
- Cleanable with a hospital grade disinfectant ●
- . Environment High Temperature Warning indicator light associated with an automatic shutoff circuit to indicate when the device is used in an environment with a temperature that is too high

SE Discussion #1 (Indications for Use / Environment of Use):
Both the bili-hut™ and Ultra Bili Light™ Model 2000 indications for use include treatment of neonatal hyperbilirubinemia. The bili-hut™ Indications for Use include treatment in the clinical and the home setting. The Ultra Bili Light™ Model 2000 Indications for Use, as per K974830's clearance letter states: "The intended use of the portable Ultra Bili Light model 2000 is to provide Home Phototherapy treatment for Neonatal Hyperbilirubinemia." Thus, upon clearance, it was used only for treatment in the home environment. However, Physician Engineered Products, Inc. used the Ultra Bili Light™ Model 2000 as the predicate device for their Bright Embrace Model SBL60 and the 510(k) summary for the Bright Embrace Model SBL60 (K110550) states the Ultra Bili Light™ Model 2000 "sites of use" include both
13
the clinical and home-use settings. This difference does not raise any new or different questions of safety or effectiveness for the subject device.
SE Discussion #2 (Eneray Source: Blue Light LED vs. Blue Light Fluorescent);
The bili-hut™ uses blue LED treatment lights and the Ultra Bili Light™ Model 2000 uses a blue fluorescent light source. Both provide an average irradiance greater than 30 µW/cm²/nm. The use of LED lights does not raise any new safety or efficacy concerns compared to the use of fluorescent lights.
SE Discussion #3 (Thermal Safetv):
The Ultra Bili Light™ Model 2000 includes a heating pad that is turned on if the Baby Tray is below 75°F (24°C). The bili-hut™ does not include a warming feature because the assembled hut was designed to minimize convective heat loss from the newborn during treatment. The bili-hut™ assembled hut is not designed to act as a warmer, but it is designed to contain the heat produced by the newborn as if the newborn were swaddled.
Both devices contain measures to protect the infant from overheating. However, the bili-hut™ cut-off temperature, 43°C (109.4°F), is higher than the Ultra Bili Light™ Model 2000 cut-off temperature, 98°F (36.7°C). The bili-hut™ over-temperature (Environment High Temperature Warning) was designed to be compliant with clause 201.11.1.2.2 of IEC 60601-2-50 (2009). The first edition of IEC 60601-2-50 had not yet been published at the time of the predicate device's submission so that most likely explains the difference from the predicate device's temperature cut-off. This difference does not raise any new or different questions of safety or effectiveness for the subject device.
SE Discussion #4 (Electrical Safety Testing, Electromagnetic Compatibility (EMC) Testina) and Biocompatibilitv Testing):
The bili-hut™ has undergone electrical safety testing and EMC testing to confirm compliance with current internationally-recognized standards, all of which are FDArecognized. The bili-hut™ has undergone biocompatibility testing for the patient contact components (nest liner and nest mattress cover) in compliance with the ISO 10993 standards. Refer to Section VII for further details about the electrical safety testing, EMC testing and biocompatibility testing. This difference does not raise any new or different questions of safety or effectiveness for the subject device.
VII. PERFORMANCE DATA - NON-CLINICAL TESTING
The expected duration of treatment with the bill-hut™ is 48-72 hours. Using ISO 10993-1:2009, this Nature of Body Contact is categorized as "Surface Device / Skin" with a "B – Prolonged (> 24hrs to 30 days)" Contact Duration for all patient-contact materials. Therefore, the following biocompatibility tests were conducted on the disposable covers and nest mattress; the bili-hut™ disposable covers and nest
14
mattress passed all of these tests:
- Cytotoxicity (ISO 10993-5:2009), MTT Method, MEM with 10% FBS Extract; .
- Sensitization (ISO 10993-10:2010), Guinea Pig Maximization Test, 0.9% . Sodium Chloride Injection Extract;
