Intended Use

The Soft Sack iv fluid warmer is indicated for the warming or thermal maintenance of intravenous fluids prior to administration. This device is intended for use with crystalloid fluids only, such as normal saline and ringers lactate. This device is intended to be used by healthcare professionals in hospital, clinical and field environments. The FloorMount iv fluid warmer is indicated for the warming or thermal maintenance of intravenous fluids prior to administration. This device is intended for use with crystalloid fluids only, such as normal saline and ringers lactate. This device is intended to be used by healthcare professionals in hospital, clinical and field environments. The Pak 2 iv fluid warmer is indicated for the warming or thermal maintenance of intravenous fluids prior to administration. This device is intended for use with crystalloid fluids only, such as normal saline and ringers lactate. This device is intended to be used by healthcare professionals in hospital, clinical and field environments. The Thermal Sack Pressure Infuser is a thermal maintenance device. It is intended for use as an accessory for use with iv fluid warmer devices to enhance the ability to deliver thermal normal iv fluids in the field, by insulating the bag and tubing. This device is intended for use with crystalloid fluids only, such as normal saline and ringers lactate. This device is intended to be used by healthcare professionals in clinical and field environments. This device has not been tested for pediatric use.

Device Description

Each of the iv fluid warmer devices (Soft Pack, FloorMount and Pak 2) employs a heating plate or heating blanket to warm or maintain the temperature of iv fluids such as normal saline and ringers lactate. These devices use a standard temperature control method and operate reliably in the range of 36-38 degrees C. The Smithworks products are designed to use a 40 watt, 12 VDC with an optional 120 VAC adaptor, for enhanced safety and portability when used in the field. The Thermal Sack Pressure Infuser is an accessory to the Smithworks iv fluid warmer components. This device is wrapped around the iv fluid bag and is used to apply even pressure to the iv fluid bag when it cannot be maintained in the standard hanging state, which applies normal gravity pressure. This device should only be used in conditions that require emergency personnel to move victims in conditions that prevent a normal gravity based suspension of the iv fluid bag, and when the rescue mission is conducted by a limited number of emergency medical personnel.

Not Found

AI/ML (Artificial Intelligence / Machine Learning)

No
The device description focuses on standard heating and temperature control methods, and there is no mention of AI, ML, or related technologies in the provided text.

Therapeutic

No
The devices mentioned are fluid warmers, which maintain or warm intravenous fluids; they do not directly treat a medical condition in a patient.

Diagnostic

The device is an IV fluid warmer, used to warm or maintain the temperature of intravenous fluids, which is a therapeutic function, not a diagnostic one.

SaMD (Software as a Medical Device)

The device description explicitly details hardware components such as heating plates, heating blankets, and a pressure infuser, indicating it is a physical device, not software-only.

IVD (In Vitro Diagnostic)

Based on the provided text, these devices are not IVDs (In Vitro Diagnostics).

Here's why:

IVDs are used to examine specimens from the human body. The intended use and device descriptions clearly state that these devices are for warming or maintaining the temperature of intravenous fluids (like saline and Ringer's lactate) prior to administration to a patient. They are not used to analyze blood, urine, tissue, or any other biological sample.
The function is physical, not diagnostic. The devices physically heat or insulate the fluids. They do not perform any diagnostic test or provide information about a patient's health status based on analyzing a specimen.

Therefore, these devices fall under the category of medical devices, but not specifically In Vitro Diagnostic devices.

§ 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)

5. Comparison with Legally Marketed Devices

Several iv fluid warmers have been cleared by FDA for use in hospital, clinical and field environments. These systems have been cleared under two product codes: iv fluid warmers have been assigned the product code LGZ and remain "unclassified," whereas products intended for use as blood/fluid warmers have been classified as BSB under 21 CFR 864.9205 Both categories of these products have been cleared as Class II medical devices.

The predicate devices cited in this submission have been cleared under the 510(k) PreMarket Notification process. The predicate devices are as follows:

Similarities:

The Smithworks iv fluid warmer product line is designed to provide external warming of iv bags containing normal crystalloid iv solutions. In this application, the Smithworks iv fluid warmers incorporate features that are substantially equivalent to the features provided by the legally marketed iv fluid warmer devices cited above. All of the iv fluid warmers are designed for use in the hospital, clinical or field environment.

Each device employs a heating element to warm iv fluids. All of the devices use a standard temperature control method and have an established range of operation for the temperature control (typically 33-41 degrees C). The Smithworks products are individually tested to operate reliably in the range of 36-38 degrees C.

As with the Hot Sack device, the Smithworks product packaging and components have been optimized for mobile use, such as rescue and emergency operations. Also, the power source for the Smithworks iv fluid warmer devices is provided by a 12V battery or 100-120 VAC. The Smithworks products are designed to use a 40 watt, 12 VDC with an optional 120 VAC adaptor, for enhanced safety and portability when used in the field.

The proposed indications for use statement for the Smithworks Company Soft Pack, FloorMount and PAK2 iv fluid warmer products is substantially equivalent to the approved indications for use statements provided in the labeling for the cited predicate devices.

Finally, Smithworks provides an optional accessory for use with its iv fluid warmer devices, the Thermal Sack Pressure Infuser, an accessory that is equivalent to the Hot Sack Optional Insulated IV Sleeve. These devices are both designed to provide thermal maintenance of previously warmed iv fluids and to help maintain a steady flow rate of iv fluids during rescue operations in hostile rescue environments, such as extreme temperature/wind chill conditions.

Differences:

The cited predicate devices that are classified under product code BSB (see Table, above) also provide "in-line" warming of blood and/or iv fluids. The Smithworks products do not provide this functionality. Smithworks iv fluid warmer products are only intended for use for the warming of iv fluid bags containing crystalloid fluids, such as Ringer's lactate or normal saline, using conduction from an external electronic component.

6. Conclusions

The Smithworks Company iv fluid warmer products, the Soft Sack, the FloorMount and the Pak2, are substantially equivalent to the identified legally marketed devices intended for use in warming iv bags containing crystalloid fluids, such as Ringer's lactate or normal saline, using conduction from an external electronic component.

The Thermal Sack Pressure Infuser is equivalent to a previously cleared device marketed as an accessory for use with iv fluid warmers to provide

KCX.0851
6 of 6

thermal maintenance of previously warmed iv bags and steady flow rates during rescue operations in hostile environments.

The potential hazards have been studied and controlled as part of the product development process, including risk analysis, test and design considerations, and planned verification and validation testing processes. The Smithworks Company iv fluid warmer products operate in hospital, clinical and field environments in a manner comparable to the predicate devices.
