Intended Use
The bubble humidifier is intended to add moisture to breathing gases for administration to patients >1 month in homecare, hospital, extended care and hospice. The bubble humidifier is a non-sterile device indicated for single-patient usage. The device is indicated for patients who require humidification of high flow supplemental breathing gases.
Device Description
The Salter Labs Bubble Humidifier (6-15 LPM) with 6 PSI (410 mbars) safety valve is an empty, disposable, non-sterile, not made with natural rubber latex, device intended to humidify breathing gas prior to delivery to a patient. The Salter Labs Bubble Humidifier (6-15 LPM) with 6 PSI (410mbars) safety valve is provided with a 6 pounds per square inch (PSI) safety valve and can operate within flow rates of 6 to 15 liters per minute (LPM). The device is used with various breathing gas sources (i.e., oxygen concentrators, gas cylinders and wall outlets) and provides connection for delivery of humidified breathing gas via face masks or cannulas, and use of optional oxygen tubing and water traps (face masks, 21 CFR 868.5580: nasal cannulas, 21 CFR 868.5340; oxygen tubing, 21 CFR 868.5860 and water traps, 21 CFR 868.5995 are 510(k) exempt). This device is a passive device and is not a cascade humidifier, is not heated and is not prefilled. The device is made of a humidifier bottle which is used to hold water during use, a lid which seals the humidifier bottle, an audible pressure relief mechanism to notify the user of a downstream occlusion and a diffuser located at the end of a PVC diffuser tube inside the humidifier bottle. The diffusor is designed to uniformly disperse the gas throughout the water. Both the bottle and lid are constructed to be easy to grip and reduce the chance of cross threading. The bottle is permanently marked with "minimum/maximum" water levels. The lid is marked with minimum source pressure, flow ranges and pressure value of the safety valve.
More Information

Not Found

No
The device description clearly states it is a "passive device" and there is no mention of any computational or learning capabilities. The description focuses on mechanical components and their function.

Yes
The device is intended to add moisture to breathing gases for administration to patients requiring humidification of high flow supplemental breathing gases, which is a therapeutic intervention.

No

The device is a bubble humidifier intended to add moisture to breathing gases; its function is for humidification and not for diagnostic purposes.

No

The device description clearly outlines physical components such as a bottle, lid, pressure relief mechanism, and diffuser tube, indicating it is a hardware device. There is no mention of software as the primary or sole component.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostics are devices used to examine specimens taken from the human body, such as blood, urine, or tissue, to provide information for diagnosis, monitoring, or screening.
  • Device Function: The description clearly states that this device is a bubble humidifier intended to add moisture to breathing gases for administration to patients. It is a passive device that humidifies air or oxygen before it is inhaled.
  • Lack of Specimen Analysis: There is no mention of the device analyzing any biological specimens from the patient. Its function is purely related to the delivery of humidified breathing gas.

Therefore, the Salter Labs Bubble Humidifier is a medical device, but it falls under a different regulatory category than In Vitro Diagnostics.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

The modified Salter Labs Bubble Humidifier (6-15 LPM) with 6 PSI (410mbars) safety valve was tested to verify that the bond strength of the new material used for the different tube and diffusor met the pre-defined performance specifications.

The test results demonstrate that the modified Salter Labs Bubble Humidifier (6-15 LPM) with 6 PSI (410mbars) safety valve is substantially equivalent to the predicate devices. No clinical testing was required for this submission. A cleaning study was performed which verified the cleaning outlined in the instructions for use. A useful life study was performed which verified performance up to 120 cleaning cycles.

Performance Data G.

The modified Salter Labs Bubble Humidifier (6-15 LPM) with 6 PSI (410mbars) safety valve was tested to verify that the bond strength of the new material used for the different tube and diffusor met the pre-defined performance specifications.

The test results demonstrate that the modified Salter Labs Bubble Humidifier (6-15 LPM) with 6 PSI (410mbars) safety valve is substantially equivalent to the predicate devices. No clinical testing was required for this submission. A cleaning study was performed which verified the cleaning outlined in the instructions for use. A useful life study was performed which verified performance up to 120 cleaning cycles.

H. Conclusions

The Salter Labs Bubble Humidifier (6-15 LPM) with 6 PSI (410mbars) safety valve data and test results (bond strength testing) demonstrate that the devices are substantially equivalent to the predicate devices. Based on the performance testing performed on the modified device safety valve and bond strength, Salter Labs Bubble Humidifier (6-15 LPM) with 6 PSI (410mbars) we have demonstrated that the modified device continue to perform substantially equivalent to the predicate devices.
