The device description and intended use focus on the physical conversion of liquid oxygen to gas and its delivery, with no mention of AI or ML technologies for control, analysis, or prediction. The performance studies rely on bench testing and comparison to a predicate device, not on data-driven model performance.
Yes.
The device provides medical oxygen treatment and supplements gases to be inhaled by a patient, directly contributing to therapy.
No
The device is described as converting liquid oxygen to gaseous oxygen for delivery to a patient, functioning as a medical oxygen treatment device. It does not mention any diagnostic capabilities such as detecting, monitoring, or analyzing physiological parameters or conditions.
No
The device description clearly outlines a physical device that stores and converts liquid oxygen to gaseous oxygen, involving hardware components like an insulated container, heat exchanger, and outlet ports. There is no mention of software being the primary or sole component.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to convert liquid oxygen to gaseous oxygen for delivery to a patient or rescue personnel to supplement environmental oxygen. This is a therapeutic and life-support function, not a diagnostic one.
- Device Description: The description details how the device stores and converts liquid oxygen for inhalation. It mentions supporting medical devices like masks and cannulas, which are used for delivering oxygen, not for performing in vitro diagnostic tests.
- Lack of Diagnostic Elements: There is no mention of the device analyzing biological samples (blood, urine, tissue, etc.) or providing information about a patient's health status based on such analysis.
- Anatomical Site: The concept of an "Anatomical Site" in the context of this device refers to where the oxygen is delivered (respiratory system), not where a diagnostic test is performed.
- Performance Studies: The performance studies focus on the device's ability to convert and deliver oxygen, not on its accuracy in diagnosing a condition.
In vitro diagnostics are devices used to examine specimens taken from the human body to provide information for diagnosis, monitoring, or screening. The DMOS does not perform any of these functions. It is a medical device used for oxygen delivery.

Intended Use / Indications for Use
The DMOS is intended to convert liquid oxygen to gaseous oxygen for delivery to a patient and/or for delivery to rescue personnel to supplement environmental oxygen at high altitudes while being carried by a rescue personnel at one-half (0.5) to fifteen (15) liters per minute (LPM) and fifty (50) pounds per square inch gauge (psig).

Device Description
The DMOS provides for storing of 1.4 liters of liquid oxygen and converting this liquid into its gaseous state. The gaseous oxygen is capable of being delivered in controlled amounts to provide medical treatment to injured patients and uncontrolled amounts to drive respiratory medical devices or supplemental oxygen in high altitude. The DMOS is capable of being filled with liquid oxygen from the Oxygen Generator System (OGS) and with current liquid oxygen storage/ filling stations.
DMOS contains liquid oxygen (LOX). The DMOS contains a thermally insulated container of liquid oxygen (LOX) that is intended to supplement gases to be inhaled by a patient. The DMOS supports medical devices provided by the user including masks, cannulas, and Bag Valve Mask (BVM) being attached to the flow control patient outlets. An empty portable liquid oxygen unit is a device, while the oxygen contained therein is a drug.
The DMOS is portable. The handle on the front control make the DMOS portable. The DMOS can be carried onboard, tied down, transported and operationally perform on various aircraft and ground vehicles.
The DMOS converts liquid oxygen from its insulated container through its heat exchanger into gaseous oxygen and finally the gaseous oxygen is available for distribution from an outlet port on the user interface. After connecting a tube assembly connector of a mask, cannula, and Bag Valve Mask (BVM) to an outlet port, masks, cannulas, and BVMs or other similar medical device (none of these devices is included in the DMOS) the patient can inhale the gaseous oxygen.

- Indications for Use of Medical Device
The DMOS is intended to convert liquid oxygen to gaseous oxygen for delivery to a patient and/or for delivery to rescue personnel to supplement environmental oxygen at high altitudes while being carried by a rescue personnel at one-half (0.5) to fifteen (15) liters per minute (LPM) and fifty (50) pounds per square inch gauge (psig).

6. Comparison to Predicate Medical Device
The BMOS (K071581) is the predicate medical device to which DMOS (K130068) is compared. Indications for Use for BMOS is that the BMOS is intended to be used by emergency response personnel in military and commercial fields to provide an emergency source of supplemental oxygen for a patient while being transported from a crisis situation to a health care facility. The BMOS is not intended to be a life sustaining or life-supporting device.
- Both the submission device and predicate device convert liquid oxygen to gaseous . oxygen
- Both devices can be used in military and commercial applications .
- Both devices supply supplemental oxygen to a patient .
- Both flow at one-half (0.5) to fifteen (15) liters per minute (LPM) and fifty (50) . pounds per square inch gauge (psig)
- The only difference between the two devices is that DMOS is capable of . supplying oxygen to rescue personnel in situations where they themselves need additional oxygen when they are in high altitude, mountainous region
BMOS & DMOS are both portable. Personnel can move a BMOS device by picking up the unit by the handle on the front face and walking with it while personnel can move a DMOS device by in the same manner. Both the BMOS and DMOS devices are similar in that they include a thermally insulated container. Both containers are designed built, and tested per 49 CFR §178.57, Specification 4L welded insulated cylinders, and are housed in aluminum sheet metal enclosures that contain heat exchangers that convert the liquid oxygen to gaseous oxygen. Both devices have ports that can be connected to tubing intended for connection to an oxygen mask or other similar medical device to ultimately supplement gases to be inhaled by a patient.
Both devices can be monitored for pressure and liquid oxygen quantity. The differences in the BMOS and DMOS are in the container size and LOX capacity. The BMOS container is a cylinder that is approximately 13.1 inches long and 5.0 inches in diameter with a LOX capacity of 2 liters while the DMOS container is a cylinder that is approximately 12.3 inches long and 4.4 inches in diameter with a LOX capacity of 1.4 liters.
The DMOS has an additional parachute port, which the BMOS does not have, that allows the military rescue personnel to plug in his/her parachutist mask for additional oxygen when they are in high altitude, mountainous region.

DMOS is a slightly smaller version of the BMOS, where both systems function exactly the same, with the exception that DMOS has the capability to provide oxygen at high altitude for rescue personnel.
