Intended Use

The Precision Flow® - Heliox is intended to warm and add moisture to breathing gases from an external source for administration to neonate/infant, pediatric and adult patients in the hospital and sub-acute institutions. It adds heat and moisture to a blended medical heliox (79% helium. 21% oxygen)/oxygen mixture and assures the integrity of the precise heliox (79% helium, 21% oxygen)/oxygen mixture via an integral oxygen analyzer. The flow rates may be from 1 to 40 liters per minute via nasal cannula.

Device Story

Precision Flow®-Heliox is a respiratory gas humidifier/blender; inputs are external heliox and oxygen gas sources. Device uses electronic blender with mass flow sensors to mix gases based on operator-set flow and oxygen percentage; proportional solenoid valves control gas flow. Integral oxygen analyzer monitors mixture integrity. Humidification occurs via disposable vapor transfer cartridge using membrane technology; no direct water-gas contact. Warmed, humidified gas delivered via triple-lumen heated tube and nasal cannula. Used in hospitals/sub-acute institutions by clinicians. Main unit contains electronics/sensors; disposable module contains water reservoir/pump. Provides real-time monitoring of flow, FiO2, and temperature; triggers alarms for faults (e.g., water level, blocked tube, gas supply). Battery backup maintains settings for 15 minutes. Benefits include precise heliox/oxygen delivery, integrated humidification, and reduced user error compared to manual blending systems.

Clinical Evidence

Bench testing only. Device met requirements for ISO 8185 (humidifiers), ISO 11195 (gas mixers), and electrical safety/EMC standards (IEC 60601 series). Performance data confirmed accurate blending of heliox/oxygen and effective humidification. No clinical data presented.

Technological Characteristics

Electronic/mechanical respiratory humidifier. Materials: polymer membrane in vapor transfer cartridge. Sensing: mass flow sensors, oxygen sensor, pressure/temperature/water level sensors. Energy: AC power with internal battery backup. Connectivity: standalone. Sterilization: N/A (disposable gas pathway). Software: firmware-controlled blending and alarm management.

Indications for Use

Indicated for neonate, infant, pediatric, and adult patients requiring warmed, humidified heliox (79% helium/21% oxygen) and oxygen therapy in hospital or sub-acute settings. Flow rates 1-40 L/min via nasal cannula.

Regulatory Classification

Heliox/Oxygen Blender, K090781 Secondary Device: Precision Flow® - Air, K072845 The Precision Medical device is a mechanical device and the Precision Flow® device is electronic/mechanical device. The Precision Medical predicate device is compared to the Precision Flow® device for mechanical aspects and the Precision Flow® - Heliox is compared to the Precision Flow® - Air for electronic functions. The Precision Medical {1}------------------------------------------------ device depends on adding external stand alone devices (i.e. flowmeter, oxygen analyzer) to it for some functions. The Precision Flow® - Heliox has the same functions residing in the unit. ### Intended Use / Indications for Use The Precision Flow® - Heliox is intended to warm and add moisture to breathing gases from an external source for administration to neonate/infant, pediatric and adult patients in the hospital and sub-acute institutions. It adds heat and moisture to a blended medical heliox (79% helium. 21% oxygen)/oxygen mixture and assures the integrity of the precise heliox (79% helium, 21% oxygen)/oxygen mixture via an integral oxygen analyzer. The flow rates may be from 1 to 40 liters per minute via nasal cannula. ## Technological Characteristics The Precision Flow® - Heliox consists of two parts: and the more of the comments of the first and with a The main unit which contains all the electrical and electronic components including the electronic blender and flow controllers. All the sensors are located in the main unit. The main unit has no water pathways and the gas pathway contains only dry gas at room temperature, and consequently does not need internal cleaning or disinfection. The disposable components comprising the disposable water module, vapor transfer cartridge and heated delivery tube. Conditions in the circulating water and gas streams are sensed remotely via the interface between the main unit and the disposable module. ## 1. Main unit: - · The flow of heliox and oxygen is measured by mass flow sensors. The mass flow sensors are configured for the specific gravity of the type of breathing gas. The blending function is independent from the type of gas. The operating software calculates the required flow of each needed to reach the target flow and oxygen percentage set by the operator. The system controls gas flows accordingly by adjusting proportional solenoid valves on the gas lines. An oxygen sensor monitors the gas mixture and signals any discrepancy between target and measured percentage. The oxygen sensor is automatically calibrated with oxygen at power-up and every 24 hours. - · Firmware running in the main unit uses sensors to monitor gas pressure, water level and water temperature, and to detect air leaks into the water circuit (bubble detector). Alarms are displayed if any parameters are {2}------------------------------------------------ outside the normal range. Other indicators show low charge in the backup battery, and the type of cartridge installed. An internal battery backup will maintain the set flow and oxygen blend for at least 15 minutes without AC power. #### 2. Disposable components: - · Vapor Transfer Cartridge. In the cartridge blended gas passes through membrane made of a specially developed polymer. Warm water circulates and diffuses as vapor through the membrane material into the gas stream. Unlike most humidifiers, there is no direct contact between the water and gas streams. The gas stream leaves the cartridge essentially saturated with vapor at the set temperature. - · Triple-lumen heated delivery tube. The warmed humidified gas passes through the center lumen. The center lumen is surrounded by two outer lumens carrying warmed water to maintain the temperature of the inner lumen and to minimize rain-out. A proprietary short nasal cannula is connected to the end of the delivery tube and passes the humidified breathing gas to the patient's nose. - · Disposable module. The module houses a water reservoir, pump, connections for the cartridge and delivery tube, and sensor interfaces to the main unit. Water is pumped past a heater plate through the outer lumens of the delivery tube. Returning water passes through the outer jacket of the Vapor Transfer Cartridge where some water is lost as vapor to the gas stream. There is no direct contact between water and gas flows. The water then returns to the pump reservoir. Heater power is adjusted continuously to maintain the set temperature. Water flows into the circuit from the water bag to replace evaporative losses in the Vapor Transfer Cartridge. Air is purged to atmosphere from the circulation via a hydrophobic filter membrane. The device front panel has a LCD display which performs the following functions: - Displays . - o Gas flow - o Delivered oxygen concentration - Temperature of gas delivered 0 - Alarms for ◆ - o Water level for humidifier - General fault o - o Blocked tube (water for humidifier) - Battery charging status o - Cartridge fault (humidifier cartridge) o {3}------------------------------------------------ - o Cartridge type (2 are available for lower flows and higher flow) - o Supply gas fault - Encoder knob . - o For selecting settings - Run / Standby button . - Status LED . - Alarm mute . # Performance Data: In all instances, the Precision Flow® - Heliox functioned as intended and the results observed were as expected.
