Intended 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 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.

The FDA identifies the device as a respiratory gas humidifier, which is classified as a therapeutic device intended to warm and add humidity to medical respiratory gases for patients.

No

The device is described as a respiratory gas humidifier intended to heat and humidify medical respiratory gases for patients, functioning as a therapeutic device rather than a diagnostic one.

No

The device description clearly outlines hardware components such as a water chamber, heated inspiratory and expiratory tubes, and temperature sensors, indicating it is a physical device, not software-only.

Based on the provided text, the Gründler's HumiCare D900 system is not an IVD (In Vitro Diagnostic) device.

Here's why:

  • Intended Use: The intended use is to heat and humidify medical respiratory gases for patients during various forms of respiratory support. This is a therapeutic function, not a diagnostic one.
  • Device Description: The device is described as a "respiratory gas humidifier" and is identified by the FDA as a "therapeutic device". Its function is to condition gases that are delivered to the patient's airway.
  • Lack of Diagnostic Activity: There is no mention of the device being used to test samples from the human body (like blood, urine, tissue, etc.) to provide information for diagnosis, monitoring, or screening.

Therefore, the Gründler's HumiCare D900 system falls under the category of a therapeutic medical device, not an In Vitro Diagnostic device.

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:

  • 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.
