The temperature probes are reusable and designed for use with monitors of Philips Model IntelliVue MP50, Mindray Model PM-9000, Datex-Ohmeda Model Cardiocap II, Drager Model Infinity Gamma XL. These devices are used by qualified medical professional only.

Device Story

Med-link Temperature Probes are reusable clinical electronic thermometers; consist of a monitor-end connector and a patient-end thermistor. Device measures patient temperature via NTC (Negative Temperature Coefficient) thermistor; resistance changes linearly with temperature. Probes are used with specific compatible monitors (Philips, Mindray, Datex-Ohmeda, Drager) to display temperature data. Operated by qualified medical professionals in clinical environments. Output provides real-time temperature monitoring to assist clinicians in patient assessment and clinical decision-making.

Clinical Evidence

Bench testing only. Performance validated against ISO 80601-2-56 and IEC 60601-1. Biocompatibility confirmed via ISO 10993-5 (cytotoxicity) and ISO 10993-10 (irritation and sensitization). Reprocessing validated per FDA guidance.

Technological Characteristics

Reusable temperature probes; NTC thermistor sensing principle; 2.25K resistance at 25°C. Materials: PVC cable, epoxy and S304 stainless steel probe end. Non-sterile. Compliance: IEC 60601-1, ISO 80601-2-56, ISO 10993-5/10.

Indications for Use

Indicated for multi-patient temperature monitoring in clinical settings. Used by qualified medical professionals only.

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.
