Intended Use

The Gründler HumiCare D900 system is intended to heat and humidify medical respiratory gases for patients. The device is for use during artificial ventilation or ventilatory support (e.g. invasive 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 breathing circuits are used for 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 heated respiratory gas humidifier. It receives gas from a ventilator, directing it into a water chamber where it is heated and humidified via passover technology to achieve 100% relative humidity. Conditioned gas is delivered to the patient via heated inspiratory tubing to prevent condensation (rain-out). System includes heater base, power supply, disposable water chambers, heated tubes, and optional antibacterial filter. Used in hospital or home environments by trained healthcare providers. Output is warmed, humidified gas; helps maintain airway moisture and prevents condensation during ventilation. Device performance is monitored via temperature sensors in inspiratory and expiratory limbs.

Clinical Evidence

Bench testing only. No clinical data provided. Testing included humidification performance, resistance, and biological safety (ISO 10993-3, -5, -6, -10).

Technological Characteristics

### Intended Use

The Gründler HumiCare D900 system is intended to heat and humidify medical respiratory gases for patients. The device is for use during artificial ventilation or ventilatory support (e.g. invasive 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 breathing circuits are used for 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 Description

The HumiCare D900 system is a respiratory gas humidifier according to 21 CER §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 passover humidification via an enhanced surface area for gas/water. The huge gas/water sufface 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 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 temperature sensors are included in the inspiratory and expiratory air tubing,

The HumiCare D900 system consists of a heater base with external power supply, connector cables, a 30day disposable water chambers, heated tubes (inspiratory), connection tube, antibacterial filter and filter heater. The 30day disposable water chamber and air tubing circuits are intended for single patient use, with the exception of when an antibacterial filter is incorporated into the circuit allowing multi-patient use of the chamber. The HumiCare D900 heater base and filter heater are intended for multi-patient re-use.

#### Substantial Equivalence

The new device is substantially equivalent to the above specified predicate devices based on:

- Similar intended use 人
- Similar operating principle
- A Similar Circuit types
- Same fundamental technological characteristics 人
- Similar performance characteristics.

Design and Verification activities were performed on the HumiCare D900 as a result of the risk analysis and product requirements. All tests confirmed the product met the predetermined acceptance criteria. In particular side-by-side testing demonstrated that the HumiCare D900 essential performance specifications (humidification performance, resistance of the humidifier) are Substantially Equivalent to the predicate devices.

Materials that contact the heated humidified gas pathway are considered to be external communication permanent duration (tissue/bone/dentin). The biological tests for warm wet air path application, in accordance with FDA Guidance #G95-1 were:

- ISO 10993-3 Genotoxicity >
- ISO 10993-5 Cytotoxicity A
- ISO 10993-6 Implantation A
- ISO10993-10 Sensitisation and Irritation

{2}------------------------------------------------

The new device complies with the applicable requirements referenced in the FDA guidance documents:

- > FDA Reviewer Guidance for Premarket Notification Submissions (November 1993)
- > FDA Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices (May 11, 2005)
- > FDA Heated Humidifier Review Guide (February 1997)

The new device was designed and tested to the following standards:

- FDA-3654 (IEC 60601-1:1988) *
- 大 FDA-3654 (IEC 60601-1-2:2007)
- > FDA-3654 (ISO 8185:2009)

## Conclusion

The indications for use, technological characteristics, and principles of operation are similar to the predicate devices. Performance data demonstrate that the new device is as safe and effective as the predicate devices. Thus the HumiCare D900 system is substantially equivalent to the predicate devices.
