#### Device Description ട.

Disposable temperature probes are used during patient temperature measurement. These probes consist of a plug connector on the adapter cable end and a thermistor on the patient end. Temperature probes measure temperature by a resistor that is sensitive to temperature changes. These probes are connected to the patient monitor by using an interconnect cable. These probes have a skin or rectal contact with adult patients. Both the skin and rectal probe are single use and provided non-sterile.

These temperature probes are typically used with legacy Nihon Kohden monitors BSM-5135A.

Products are packed individually into a plastic bag in non-sterile condition. Package label describes product

Justifications for differences between Caremed Temperature Probe and the predicate device are shown as below:

Different (1): It's different with the patient contacted material of predicate device. However, it's conformed with ISO 10993 series standard. According to analysis results, all the Patient Contacting Materials shows no cytotoxicity, irritation response was negligible and no sensitization. Thus, different material will not raise any safety or biocompatibility issues.

Different (2): The cable length of proposed device is different with predicate device. All subject devices were conducted performance testing according to ISO 80601-2-56. Thus, different cable length will not raise any safety or performance issues.

Different (3): It's different with the cable material of predicate device. However, it's conformed with ISO 10993 series standard. According to analysis results, all the cable shows no cytotoxicity, irritation response was negligible and no sensitization. Thus, different material will not raise any safety or biocompatibility issues.

Different (4): The subject device contains an interconnect cable which is designed to connect the monitor and the temperature probe. All components were conducted safety, EMC and performance testing. Thus, this different will not raise any question of safety and effectiveness.

Different (5): The compatible monitors of proposed devices are different from the predicate device. The

{6}------------------------------------------------

proposed devices are intended to use with Nihon Kohden monitors and the predicate devices are intended to use with Draeger and Siemens monitors. The core component of temperature probe is Negative Temperature Coefficient (NTC) which is identical to the NTC used in predicate device. The NTC determines the accuracy and range of temperature measurement. Therefore, the indication for use of proposed devices is essentially the same as predicate device.

#### Performance Data 8.

The following performance data were provided in support of the substantial equivalence determination.

## Biocompatibility testing

The biocompatibility evaluation for the Caremed Temperature Probes was conducted in accordance with the FDA Guidance for Industry and Food and Drug Administration Staff: Use of International Standard ISO 10993-1, "Biological evaluation of medical devices - Part 1: Evaluation and testing within a risk management process". The battery of testing included the following tests:

- Cytotoxicity .
- Sensitization .
- Irritation .
- Rectal Irritation (Rectum probes only) .

The skin temperature probes are considered surface contacting for a duration of exceed 24 hours but not 30 days.

The rectal temperature probes are considered mucosal contacting for a duration of not exceed 24 hours.

## Non-clinical data

The following standard and test requirements have been applied to Caremed Temperature probes with adaptor cable and compatible patient monitor Nihon Kohden Model BSM-5135A.

| Test | Description | Result |
|---------------------|------------------------------------------------------------------------------------------------------------------------|--------|
| Safety | Ensures the temperature probes meet the requirements of IEC 60601-1 electrical safety | Pass |
| EMC | Ensures the temperature probes meet the requirements of IEC 60601-1-2 and ISO 80601-2-56 electromagnetic compatibility | Pass |
| Laboratory accuracy | Not greater than 0.3 °C for a continuous clinical thermometer that is not an adjusted mode clinical thermometer | Pass |
| Time response | Heating transient time < 150s | Pass |

The thermometer testing followed ASTM E1112 and ASTM 80601-2-56

#### 9. Conclusion

Performance testing and compliance with voluntary standards demonstrate that the proposed subject device is substantially equivalent to the predicate device.
