Indications for Use
The Gründler's HumiCare D900 system is intended to heat and humidify medical respiratory gases for patients. The device is for use during artificial ventilatory support (e.g. invasve ventilation via tracheal tube or cannula), non-invasive ventilation, or respiratory therapy by means of a mask or other patient interface. Heated breathing circuits are intended to provide warmed and/or humidified breathing gases before entering the patient airway reducing or eliminating water. They are accessories for the Gründler's HumiCare D900. The heated breath or flow rates greater than 3L/min. The system is for use in hospital/institutional environment or in the home environment by medically trained healthcare users.
Device Story
HumiCare D900 is an active pass-over respiratory gas humidifier; warms and humidifies medical gases for patients receiving ventilatory support. Ventilator gas enters water chamber; heated/humidified gas travels through heated inspiratory tubing to patient interface. System includes heated breathing circuits to prevent condensation (rain out). Temperature sensors in inspiratory tubing provide feedback for closed-loop temperature regulation. Used in hospital, institutional, or home settings by medically trained healthcare users. Output is conditioned gas at controlled temperature and humidity. Benefits include optimized gas delivery and reduced condensation in breathing circuits, improving patient comfort and safety during respiratory therapy.
Clinical Evidence
Bench testing only. Side-by-side testing verified performance against HumiCare D900 (K122705) specifications, including gas temperature accuracy, surface temperature of tubes, and condensation prevention per ISO 8185. Biocompatibility evaluations (ISO 10993-3, -5, -6, -10) and testing for volatiles, particulates, and leachables were performed. Cleaning and reuse validation for the T2 plug-in sensor was completed.
Technological Characteristics
Active pass-over humidifier; heated water chamber; heated inspiratory/expiratory tubing. Materials biocompatibility per ISO 10993-1. Closed-loop temperature regulation via integrated sensors. Connectivity: T2 plug-in sensor. Sterilization/Cleaning: Validated for reuse. Software: Embedded control for temperature regulation.
Indications for Use
Indicated for patients requiring heated and humidified respiratory gases during invasive ventilation (tracheal tube or cannula), non-invasive ventilation, or respiratory therapy via mask or other interface. For use in hospital, institutional, or home environments by medically trained healthcare users.

Description The HumiCare D900 system is a respiratory gas humidifier according to 21 CFR §868.5450. A respiratory gas humidifier is identified by the Food and Drug Administration (FDA) as a therapeutic device that is intended to warm and add humidity.
> The HumiCare D900 including heated air tubings is an active heated humidifier which employs a pass-over humidification via an enhanced surface area for gas/water. The huge gas/water surface area is resulting in an output of gas with a temperature almost identical to that of the water with a relative humidity of 100%.
> The principle operation of the HumiCare D900 is to direct the gas mixture from the ventilator's outlet into the humidifier's water chamber via air tubing. There it is heated and humidified by means of heated water. A heated inspiratory tube is used to transport the conditioned gas from the water chamber's outlet to the patient.
> Depending on the patient interface an inspiratory tube or inspiratory and expiratory tubes can be used for the humidification with HumiCare D900. The inspiratory limb can further include an antibacterial filter with filter heater to reduce condensation. In order to minimize condensation (rain out), both inspiratory and expiratory air tubing can be actively heated. Therefore a temperature sensor is included in the inspiratory air tubing to control the temperature regulation of the air tubing.

Clinical Testing Clinical testing is not required, bench testing alone is sufficient to demonstrate the product remains substantially equivalent to the predicate device HumiCare D900 (K122705). Non-Clinical Testing Side-by-Side bench testing was performed to verify that the HumiCare D900 met the predetermined pass/fail requirements of the
> HumiCare D900 System Specification when compared to the predicate devices [HumiCare D900 (K122705)]. This bench testing included testing the performance of each therapy mode which included:
- . Determination of the accuracy of displayed gas temperature
- . Determination of surface temperature of the tubes
- System performance according to ISO 8185
- . Absence of condensate formation
As was the case with the predicate, the HumiCare D900 materials not previously cleared by FDA were subject to appropriate biocompatibility evaluations according to ISO 10993-1. Materials used the construction of components that:
- contact the heated humidified gas pathway have been ● classified as permanent "external communicating devices" (with tissue/bone/dentin)
As relevant and to support the biocompatibility evaluation of each tube component, following biological effects (selected in accordance with FDA guidance #G95-1) were assessed:
- Genotoxicity (ISO 10993-3) ●
- Cytotoxicity (ISO 10993-5) .
- Implantation (ISO 10993-6) ●
- . Sensitization (ISO 10993-10)
In addition the device was tested for volatiles, particulates and leachable substances. The device was shown to pass all requirements.
{6}------------------------------------------------
Validation of cleaning and reuse was completed to establish that the T2 plug in sensor can be reused in the home or hospital/institutional environment.
#### Substantial equivalence
#### Comparison with previously cleared HumiCare D900
The modified device has the following similarities to the previously cleared HumiCare D900:
- Same intended use 久
- A Similar operating principle
- Similar circuit types A
- A Same fundamental technological characteristics
- A Similar performance characteristics.
- A Similar manufacturing process
Design and Verification activities were performed on the modified HumiCare D900 as a result of the risk analysis and product requirements. All tests confirmed that the product met the predetermined acceptance criteria and that the modified HumiCare D900 essential performance specifications (humidification performance, resistance of the humidifier) are substantially equivalent to the predicate device (K122705).
The modified device complies with the applicable requirements referenced in the FDA quidance documents:
- FDA Reviewer Guidance for Premarket Notification A Submissions (November 1993)
- A FDA Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices (May 11, 2005)
- > FDA Heated Humidifier Review Guide (February 1997)
- Conclusion The indications for use, technological characteristics, and principles of operation are similar to the predicate device. Performance data demonstrate that the modified HumiCare D900 system is substantially equivalent to the predicate device.
