The Infant Heel Warmer™ Heel Snuggler® are instant warm packs intended to be used on an infant's heel to increase blood circulation to the area to aid in the drawing of blood for analysis. It is a single use, nontoxic, non-sterile, disposable device. The Infant Heel Warmer™, Heel Snuggle® have two configurations, the Heel Snuggler®, which is designed to conform to the shape of the infant's heel, and the standard Infant Heel Warmer™. The devices are primarily used in hospitals, Doctor's offices, and other healthcare settings.
The Infant Heel Warmer™/Heel Snuggler® is a single use, disposable pouch that is filled with a super saturated solution of food grade sodium acetate and a catalyst disk. When the catalyst disk inside the packet is flexed by the user, the catalyst disk reacts with the non-toxic solution and initiates a chemical exothermic crystallization of the sodium acetate, generating heat. When activated at 75°F, both models will reach between 104-107°F and then gradually decrease in temperature over time.
The Heel Snuggler® is a butterfly shape with two straps and the Infant Heel Warmer™ is rectangular with one strap. Straps with adhesive ends are attached to the packet for securing the heel warmer to the infant's foot, if desired. Immediately following activation of the user rests the bottom of the infant's foot on one portion of the packet and holds the other portion of the packet to the ankle. The straps with adhesive tape on the end are then fitted across the infant's foot and ankle and secured to the opposite side of the adhesive portion of the strap is affixed to the packet only, not the infant's skin. The straps on the heel warmer are perforated, which enables the user to easily tear the straps and remove the heel warmer from the infant's foot after use.
The provided text details a 510(k) summary for the Infant Heel Warmer™/Heel Snuggler®, arguing for its substantial equivalence to a predicate device. This submission primarily focuses on bench testing and comparison of technical specifications, not on an AI/ML-driven medical device that would involve a study of the type described in the request.
Therefore, many of the requested elements are not applicable to this document. The document describes a physical medical device (a warming pack), not a software or AI-based diagnostic tool.
However, I can extract the acceptance criteria and the "study" (bench testing) that was performed to demonstrate the device meets those criteria, as well as addressing the applicable parts of your request.
Here's a breakdown based on the provided text, with notes on what is not applicable:

Rapid Aid Infant Heel Warmer is primarily used in hospitals, doctor's offices, and other healthcare facilities. It is an instant warm pack intended to be used on an infant's heel to increase blood circulation to the area to aid in the drawing of blood for analysis. It is a single use, non-toxic, non-sterile, disposable warmer.
The Rapid Aid Infant Heel Warmer is a self contained unit comprised of a flexible, poly/nylon outer pouch containing:
- a) A metal disc that can be flexed during activation,
- b) Liquid solution of food grade sodium acetate and water,
- c) Minute crystals of sodium acetate.
An adhesive tape is attached to the top of the unit is activated by squeezing firmly on the inner fluid pouch, this will cause the inner perforated pouch to activate. Rapid crystallization occurs when the liquid contents are exposed to the minute crystals of sodium acetate contained within the poly/nylon outer pouch. This exothermnic reaction causes the unit to heat up to 104ºF. The adhesive tape strip is used to hold the warmer in place if desired.
Here's an analysis of the provided text regarding the Rapid Aid Instant Disposable Infant Heel Warmer, focusing on acceptance criteria and study details:
1. Table of Acceptance Criteria and Reported Device Performance
The main performance characteristic tested for this device is its temperature profile.
Acceptance Criteria Category | Acceptance Criteria (Implicit) | Reported Device Performance (New Device) | Reported Device Performance (Predicate Device) |
---|---|---|---|
Maximum Temperature | Within specified range | 102.6 ± 0.2 °F | 102.2 ± 0.4 °F |
Dwell Time (within 101-104 °F) | Within specified range | 8.5 ± 1.0 min | 8.5 ± 0.8 min |
Note: The exact numerical "specified range" for maximum temperature and dwell time is not explicitly stated as a formal acceptance criterion but is implied by the comparison to the predicate device and the statement "both within the specified range for this device."
2. Sample Size Used for the Test Set and Data Provenance
- Sample Size: Not explicitly stated. The document mentions "The Infant Heel Warmer with Disc was tested against the predicate device," implying a test set, but does not provide the number of units tested.
- Data Provenance: Not explicitly stated, but it's a bench test conducted by the manufacturer, Rapid Aid Corp. (Canada). This would be prospective data generated for the 510(k) submission.

The Respironics Heel Snuggler infant heel warmer is intended for use whenever circulation needs to be stimulated in the infant heel in order for blood sampling to occur.
The Heel Snuggler is a butterfly shaped packet that is filled with a non-toxic solution and a catalyst disk. Two straps with adhesive ends are attached to one side of the packet for securing the heel warmer to the infant's foot. Immediately following activation of the user rests the bottom of the infant's foot on the larger portion of the packet and holds the smaller portion of the packet to the ankle. The straps with adhesive tape on the end are then fitted across the infant's foot and ankle and secured to the opposite side of the packet. The adhesive portion of the strap is affixed to the packet only, not the infant's skin. This forms a boot shape around the infant's foot. The heel warmer are perforated, which enables the user to easily tear the straps and remove the heel warmer from the infant's foot after use.
When the catalyst disk inside the packet is flexed by the catalyst reachs with the solution a ri initiates a chemical exothermic reaction, which produces warmth.
The Heel Snuggler Infant Heel Warmer is a Class I device, and the provided documentation is a 510(k) summary for its clearance. Medical devices in Class I, especially those cleared via a 510(k), are generally considered low risk and do not require the rigorous clinical efficacy studies that higher-risk devices or software as a medical device (SaMD) might.
From the provided text, there is no information about an AI/ML powered device, acceptance criteria or a study that proves a device meets acceptance criteria in the context of an AI/ML device. The document describes a traditional medical device (an infant heel warmer) and its 510(k) clearance process.
Therefore, I cannot provide the requested table and information about acceptance criteria and studies related to an AI/ML device. The document specifically states:
- "Design verification tests were performed on the Heel Snuggler as a result of the risk analysis and product requirements. All tests were verified to meet the required acceptance criteria." This indicates that the device underwent engineering and design verification testing to ensure it met pre-defined product requirements and safety standards, which is typical for a non-AI/ML medical device.
- The comparison is made to a predicate device (DeRoyal Industries, Inc. Infant Heel Warmer (K954716)) to establish substantial equivalence, which is the standard pathway for 510(k) clearance for traditional medical devices.
The information you are requesting (AI/ML relevant details) is not present in this document because the device described is not an AI/ML product.

- MediHEAT Infant Heel Warmer is primarily used in hospitals, Doctor's offices, and other healthcare facilities.
- Normally, Medical Practitioners squeeze the heels of Infants to increase blood circulation in the area before drawing blood for analyses.
- The Infant Heel Warmer is used to warm the heel of an Infant to increase blood circulation to the area to facilitate blood sampling.
The MediHeat Infant Heel Warmer is a self-contained unit comprised of a flexible Nylon/Polyethylene bag containing the ingredients: a) Food grade sodium acetate, b) Water and c) Activator disk. When the disk is clicked, it activates the sodium acetate solution causing it to pass from the liquid phase to a solid phase (crystallization), making it exothermic. d) An adhesive tape to hold the warmer in place. It heats up to a maximum temperature of up to 105°F and gradually diminishes.
Here is the detailed breakdown of the acceptance criteria and the study that proves the device meets them, based on the provided text:
Acceptance Criteria and Device Performance Study
The MediHEAT Infant Heel Warmer is a simple device designed to warm an infant's heel to facilitate blood drawing. The acceptance criteria and supporting study primarily focus on its temperature characteristics and equivalence to predicate devices.
1. Table of Acceptance Criteria and Reported Device Performance
Acceptance Criteria | Reported Device Performance |
---|---|
Maximum Temperature | Up to 105°F |
Duration of Heat | Approximately 30 minutes |
Gradual Diminishment of Temperature | Temperature diminished gradually |
Equivalence to Predicate Devices (chemical reaction) | Substantially equivalent to listed predicate devices (PRISM, Omni Warm, Baxter, DeRoyal, Tempra) |
Equivalence to Predicate Devices (temperature output) | Temperature output is well within the range of the predicate devices. |
Conclusion from Studies: The performance of MediHEAT Infant Heel Warmer is similar and substantially equivalent to that of other commercially available Infant Heel Warmers.
2. Sample Size Used for the Test Set and Data Provenance
- Sample Size: Not explicitly stated, but the study compared the MediHEAT Infant Heel Warmer against "Predicate devices, bought in open market." This implies testing was done on at least one unit of each predicate device and at least one unit of the MediHEAT device.
- Data Provenance: The testing was conducted "in our lab" (referring to MediHeat, Inc.'s lab) which suggests internal testing. The country of origin for the data is therefore likely the USA (Dalton, GA). The study appears to be prospective as it involved testing new devices for their performance characteristics.
3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications
- None. For this type of device (a heat pack), the "ground truth" is objective physical measurements (temperature, duration) rather than expert interpretation. Experts are not mentioned as being involved in establishing the ground truth for this device's performance study.
4. Adjudication Method for the Test Set
- None. Adjudication methods like 2+1 or 3+1 are typically used for studies involving subjective human interpretation of data (e.g., medical images). This study involves direct physical measurements of temperature over time, which do not require interpretive adjudication.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done
- No. An MRMC study is not applicable here. This device warms a physical object (an infant's heel) and its performance is measured by objective temperature readings, not by human reader interpretation of complex data.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was done
- Yes, effectively. The "study" described is a standalone performance test of the device itself. There is no algorithm or human-in-the-loop component for the function of a heel warmer; it's a direct physical-chemical reaction. The performance characteristics (temperature, duration) were measured directly from the device.
7. The Type of Ground Truth Used
- Objective Physical Measurements: The ground truth was established through direct measurement of temperature and duration of heat from the devices.
8. The Sample Size for the Training Set
- Not Applicable. This device is a physical product, not an AI or machine learning algorithm. Therefore, there is no "training set" in the computational sense. The device's performance is inherent to its design and chemical composition, not learned from data.
9. How the Ground Truth for the Training Set was Established
- Not Applicable (as there is no training set for this type of device).

The Baxter Sodium Acetate Infant Heel Warmer™ is a single-use, non-sterile device. It is a heat therapy pack intended to be used on an infant's heel in order to increase peripheral blood flow and oxygenation prior to blood sampling.
The Baxter Sodium Acetate Infant Heel Warmer™ is comprised of a polyethylene/BON pouch enclosing the phase change chemical and the activator disk-like trigger. Upon pinching and flexing trigger also located within the pouch, aluminum oxide grit is released into the sodium acetate and water mixture thus initiating a chemical exothermic reaction. The hot pack immediately reaches a maximum temperature of 104 °F +/- 2.9 °F and gradually diminishes over time.
Here's an analysis based on the provided text, though it's important to note that the document describes a medical device (infant heel warmer) and not an AI/ML-driven diagnostic tool. Therefore, many of the requested categories related to AI performance, ground truth, and expert evaluation are not directly applicable. I will interpret the acceptance criteria and "device performance" in the context of a physical medical device.
Acceptance Criteria and Study for Baxter Sodium Acetate Infant Heel Warmer™
The provided document, K961154, is a "SUMMARY OF SAFETY AND EFFECTIVENESS" for a medical device, not a study evaluating an AI algorithm. Therefore, the questions related to AI/ML performance, ground truth establishment, expert review, training sets, and MRMC studies are not directly relevant to this document. I will focus on the information that is applicable to a physical device's performance and safety assessment.
