Indications for Use
Sensatronic Reusable Temperature Probes are intended to be used for monitoring temperature. The temperature probes are designed for use with GE Healthcare monitoring systems, Schiller and other monitors compatible with YSI 400 Series temperature probes. The probes are indicated for use by qualified medical personnel only. Prescription use only.
Device Story
Sensatronic Reusable Temperature Probes are clinical electronic thermometers designed for continuous temperature monitoring. The device consists of a thermistor-based probe with a sealed phono plug connector, internal Kevlar fibers for durability, and a biocompatible thermoplastic rubber (TPR) jacket. It is available in various configurations for rectal/esophageal or skin application. The device is used in clinical settings by qualified medical personnel; it connects to compatible patient monitoring systems (e.g., GE Healthcare, Schiller) that utilize the YSI 400 resistance specification. The probe senses temperature via a negative temperature coefficient (NTC) thermistor; the monitor processes the resistance signal to display patient temperature. This real-time data allows clinicians to track patient thermal status, facilitating clinical decision-making regarding patient care and intervention. The probes are reusable, supporting manual/machine cleaning, disinfection, and steam sterilization.
Clinical Evidence
No clinical data. Substantial equivalence is supported by bench testing, including electrical safety, electromagnetic compatibility, usability, accuracy per ISO 80601-2-56, biocompatibility (ISO 10993), and validation of cleaning, disinfection, and steam sterilization methods. Durability testing confirmed performance after 300 cleaning/disinfection cycles and 100 steam sterilization cycles.
Technological Characteristics
Thermistor-based temperature sensor (NTC, YSI 400 series compatible). Materials: Biocompatible thermoplastic elastomer (cable/tip), stainless steel (disks). Form factor: Rectal/esophageal (4.0mm, 3.2mm, 2.3mm) and skin (16mm, 10mm, 6mm) probes. Connectivity: Wired (phono plug/proprietary connectors). Sterilization: Steam autoclave (132°C). Standards: IEC 60601-1, IEC 60601-1-2, ISO 80601-2-56, ISO 10993, ISO 14971.
Indications for Use
Indicated for temperature monitoring in patients by qualified medical personnel using compatible GE Healthcare, Schiller, or YSI 400 Series monitoring systems.
Regulatory Classification
Identification
A clinical electronic thermometer is a device used to measure the body temperature of a patient by means of a transducer coupled with an electronic signal amplification, conditioning, and display unit. The transducer may be in a detachable probe with or without a disposable cover.
Special Controls
(1) Device is not a clinical thermometer with telethermographic functions; (2) Device is not a clinical thermometer with continuous temperature measurement functions; and (3) Appropriate analysis and testing (such as that outlined in the currently FDA-recognized editions, as appropriate, of ISO 80601-2-56, “Medical electrical equipment—Part 2-56: Particular requirements for basic safety and essential performance of clinical thermometers for body temperature measurement,” or ASTM E1965, “Standard Specification for Infrared Thermometers for Intermittent Determination of Patient Temperature,” or ASTM E1112, “Standard Specification for Electronic Thermometer for Intermittent Determination of Patient Temperature,” or ASTM E1104, “Standard Specification for Clinical Thermometer Probe Covers and Sheaths”) must validate specifications and performance of the device.
