Intended Use
These devices are indicated for use as a barrier accessory to digital thermometers while taking rectal, oral or axillary temperature measurements. These sheaths are non-sterile and intended for single use only. This accessory is contraindicated for use with broken skin.
Device Description
The Medline Digital Thermometer Non-Lubricated Probe Sheath is an accessory to a clinical electronic thermometer, which is intended to measure body temperature. The Medline Digital Thermometer Non-Lubricated Probe Sheath is a flexible plastic sheath that is used to cover the transducer of clinical electronic thermometers while taking body temperature measurements from the oral, axillary, or rectal measurement sites and acts as a barrier to prevent possible contamination of the device during temperature measurement. The sheath is an over-the-counter (OTC), disposable, single use, nonlubricated, and non-sterile device that is compatible with most digital stick thermometers.
More Information

No
The device is a simple plastic sheath and the description contains no mention of AI or ML.

No
The device is described as an accessory to a digital thermometer, providing a barrier to contamination but not directly measuring, treating, or diagnosing a medical condition itself.

No

The device is a probe sheath for a thermometer, acting as a barrier to prevent contamination, not to diagnose a condition.

No

The device is a physical probe sheath, a hardware accessory, not a software-only medical device.

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

Here's why:

  • Intended Use: The intended use is clearly stated as a "barrier accessory to digital thermometers while taking rectal, oral or axillary temperature measurements." This describes a physical barrier for hygiene and contamination prevention during a temperature measurement, which is a physiological measurement, not an in vitro diagnostic test.
  • Device Description: The description reinforces its function as a "flexible plastic sheath that is used to cover the transducer of clinical electronic thermometers" and acts as a "barrier to prevent possible contamination." This aligns with a physical accessory for a medical device, not a device that performs a test on a sample taken from the body.
  • No mention of biological samples or analysis: IVD devices are designed to perform tests on biological samples (like blood, urine, tissue, etc.) to provide information about a person's health. This device does not interact with or analyze any biological samples.
  • Performance Studies: The performance studies focus on physical properties like compatibility, leakage, and tensile strength, which are relevant to a physical barrier accessory, not an IVD test.

In summary, the device's purpose is to provide a hygienic barrier for a thermometer, which is used for a physiological measurement. It does not perform any diagnostic testing on biological samples, which is the defining characteristic of an IVD.

Discussion

The application site is different between the proposed device and the predicate. Biocompatibility was conducted per ISO 10993, "Biological Evaluation of the Medical Devices – Part 1: Evaluation of Testing within a Risk Management Process." to address this difference.

Summary of Non-Clinical Testing

Testing was conducted to demonstrate safety and effectiveness of the Medline Digital Thermometer Non-Lubricated Probe Sheath. A summary of testing is presented below with more information provided in the applicable sections.

Biocompatibility Testing

The biological evaluation for the Medline Digital Thermometer Non-Lubricated Probe Sheath was conducted in accordance with FDA guidance document, "Use of International Standard ISO 10993, "Biological Evaluation of Medical Devices Part 1: Evaluation and Testing" and ISO 10993-1 "Biological Evaluation of the Medical Devices – Part 1: Evaluation of Testing within a Risk Management Process."

The following Biocompatibility tests were performed:

  • ISO 10993-5: Cytotoxicity ●
  • ISO 10993-10: 2010: Skin Sensitization ●
  • ISO 10993-10: 2010: Skin Irritation ●

Performance Testing (Bench)

Performance testing on the Medline Digital Thermometer Non-Lubricated Probe Sheath was conducted for compatibility and leakage per the ASTM E1104-98 (2016): Standard Specification for Clinical Thermometer Probe Covers and Sheaths and tensile strength.
