Intended Use
Intended Use: DoubleCHEK is intended to indicate whether the tip of a naso/oro gastric tube tip is in an acidic or CO2 environment during or after initial placement. The DoubleCHEK is NOT intended to confirm the location of the naso/oro gastric tube. Indications for Use: The DoubleCHEK is indicated for use with an in-situ naso/oro gatric tube. It is intended to indicate whether the tip of a naso/oro gastric tube is in an acidic or CO2 environment during or after initial placement. It is NOT intended to confirm the location of the naso/oro gastric tube. The device is intended to be used by Health Care Professionals on all patients within a health care setting. The device is intended to be used with a single patient for up to 24 hours.
Device Description
The proposed device, DoubleCHEK DC-1001 is a hand-held, non-powered disposable device which consists of CO2 and pH chambers ultrasonically welded to the device upper (top) and the reservoir interface. pH and CO2 indicator papers are integrated into the design directly underneath the top so they are visible to the users next to the primary device label which contains the color scale. There are three ports where accessories are intended to the device to enable use: - The Syringe Port: A male ENFit connector designed per ISO 80369-3:2016. - The NG Tube (NGT) Port: A female ENFit connector designed per ISO 80369-3:2016. - The Reservoir Interface: A 22 mm bung style connector. To use the proposed device, the user attaches the reservoir to the reservoir interface, the naso/orogastric tube to the NGT Port and the syringe to the Syringe Port. The user then pumps the syringe (withdraws the plunger) to aspirate either liquid (stomach contents) or gas (exhalation gas). The gaseous aspirate will traverse the sample pathway to the CO2 indicator paper, where the presence or absence of CO2 can be detected via a color change in the paper. The liquid aspirate will traverse through the sample pathway to the pH paper, which will indicate pH level via a color change in the paper.

No
The device description details a purely mechanical and chemical process using indicator papers for detection, with no mention of computational analysis, algorithms, or learning.

No.
The device is intended to indicate whether the tip of a naso/oro gastric tube is in an acidic or CO2 environment, which is a diagnostic function, not a therapeutic one. It does not provide treatment or mitigation of a disease or condition.

No

The device is intended to indicate the presence of acidic or CO2 environments, which can aid in determining the general location of a tube (e.g., in the stomach or airway), but it is explicitly stated that the device "is NOT intended to confirm the location of the naso/oro gastric tube." This statement distinguishes it from a diagnostic device, which would typically provide a definitive diagnosis or confirmation of a state or condition. Instead, it seems to provide an indication or a piece of information rather than a diagnosis itself.

No

The device description clearly states it is a "hand-held, non-powered disposable device" consisting of physical components like chambers, ports, and indicator papers. It is a hardware device that uses chemical reactions (color change of indicator papers) to provide information, not software processing.

Based on the provided information, the DoubleCHEK device is likely considered an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The device is intended to indicate whether the tip of a naso/oro gastric tube is in an acidic or CO2 environment. This involves analyzing a sample (aspirated liquid or gas) taken from the patient.
  • Mechanism: The device uses indicator papers (pH and CO2) that change color based on the chemical properties of the aspirated sample. This is a classic method used in in vitro diagnostic tests to detect the presence or level of specific substances in a biological sample.
  • Sample Type: The device analyzes aspirated liquid (stomach contents) or gas (exhalation gas), which are biological samples.
  • Purpose: While the device is not intended to confirm the location of the tube, it is intended to provide information about the environment the tube tip is in, which is derived from analyzing a sample from that environment. This information is used to aid in the placement process.

Key aspects that align with the definition of an IVD:

  • It is used to examine specimens derived from the human body (aspirated liquid/gas).
  • It provides information about a physiological state (acidic or CO2 environment).
  • It uses chemical indicators to perform the analysis.

While the device is used in conjunction with a medical procedure (tube placement), the core function of analyzing a biological sample in vitro (outside the body) to provide diagnostic information about the environment is consistent with the definition of an IVD.

The fact that it's a simple, non-powered device doesn't preclude it from being an IVD. Many simple tests, like pH strips or some rapid diagnostic tests, are considered IVDs.
