Intended Use

Esophageal/Rectal Temperature Probe, Catalog Numbers 483M-9, 483M-12, and 491B: The CSZ esophageal/rectal temperature probe is intended for use in routine continuous monitoring of the esophageal or rectal temperature as an indicator or core body temperature. The probe is designed for placement in the esophagus or rectum. Esophageal Stethoscope with Temperature Sensor, Catalog Numbers 493M-9, 493M-12, 493M-18, and 493M-24: The CSZ esophageal stethoscope with temperature sensor is intended for use when the esophageal temperature is continuously monitored along with the auscultation of the heart and lung sound as an indicator of core body temperature and cardio-pulmonary performance.

Device Story

Disposable temperature probes utilize thermistors to sense core body temperature. Esophageal/rectal probes provide continuous temperature monitoring; esophageal stethoscopes provide simultaneous temperature monitoring and heart/lung sound auscultation. Signals from the thermistor are transmitted to an external monitoring unit for processing and display. Used in clinical settings by healthcare providers to assess patient core temperature and cardio-pulmonary performance. Output allows clinicians to monitor patient status continuously, facilitating clinical decision-making regarding patient thermal and respiratory stability.

Clinical Evidence

Bench testing only. Compliance with BS EN 12470-4 (Clinical Electronic Thermometers) verified performance requirements.

Technological Characteristics

Disposable probes; thermistor-based temperature sensing; electrical conductors for signal transmission; compatible with external monitoring units. Complies with BS EN 12470-4.

Indications for Use

Indicated for patients requiring continuous core body temperature monitoring via esophageal or rectal placement, or simultaneous core temperature monitoring and heart/lung sound auscultation via esophageal stethoscope.

Regulatory Classification

Identification

An esophageal stethoscope with electrical conductors is a device that is inserted into the esophagus to listen to a patient's heart and breath sounds and to monitor electrophysiological signals. The device may also incorporate a thermistor for temperature measurement.

#### Predicate Devices:

# Smiths Level 1 Esophageal/Rectal Temperature Probe; and

# Esophageal Stethoscope With Temperature Sensor Probe

goth devices are originally, listed under Respiratory Support Products, Inc. as referenced in 510K Sumber's: K864043 & K864044

### Device Description:

isposable Temperature Probes using thermistors as temperature sensors. The signal of the sensor s processed and displayed by the monitoring unit.

### Intended Use:

ontinuous measurement of core body temperature through the esophagus or the rectum.

## Comparison to the Predicate Device:

he CSZ Esophageal/Rectal Probes and Esophageal Stethoscope are substantially equivalent to he Smiths Level 1 Esophageal/Rectal Probes and Esophageal Stethosoped

## Discussion of Non-clinical Tests performed:

esting was done in accordance with BS EN 12470-4, Clinical Thermometers.

## Conclusion:

The CSZ Esophageal/Rectal Probe and Esophageal Stethoscope have the same intended use and echnological characteristics as the cleared devices (Smiths Level 1 Esophageal/Rectal Probes and Esophageal Stethoscope). The performance testing has shown that the CSZ products included in his pre-market submission meet the requirements of EN 12470-4 for Clinical Electronic hermometers, and therefore maintain the same levels of safety and effectiveness as the predicate evice currently in commercial distribution.

certify that, in my capacity as the Director of Quality and Regulatory Affairs of Cincinnati Sub-Zero Products Inc., I believe i of the best of my knowledge, that all risher and regulation Analis of Chication are truthful and accurate nd that no material fact has been omitted.
