Intended Use

Unimed Temperature Probes are intended to be used for monitoring temperature. The temperature probes are reusable and designed for use with monitors of Philips, Marquette, Mindray, Spacelabs, Siemens, Artema/S&W and other monitors compatible with YSI 400 series temperature probes. These devices are indicated for used by qualified medical personnel only.

Device Story

Unimed Temperature Probes (Skin and General Purpose models) are reusable medical devices used to monitor patient temperature. The device consists of a patient-end thermistor and a monitor-end connector, sometimes utilizing an extension cable. The thermistor acts as a temperature-sensitive resistor, converting thermal changes into electrical signals processed by compatible patient monitors (e.g., Philips, Marquette, Mindray, Spacelabs, Siemens, Artema/S&W). Used in clinical settings by qualified medical personnel, the probes provide continuous temperature data to the monitor, enabling healthcare providers to track patient thermal status and inform clinical decision-making. The device benefits patients by facilitating accurate, continuous temperature monitoring.

Clinical Evidence

Bench testing only. Compliance demonstrated with IEC 60601-1 (general safety), EN 12470-4 (performance of electrical thermometers), ISO 10993-5 (in vitro cytotoxicity), and ISO 10993-10 (irritation and delayed-type hypersensitivity).

Technological Characteristics

Reusable temperature probes featuring thermistor sensing technology. Accuracy maintained in 25-45°C range. Compatible with YSI 400 series systems. Materials include various cable and plug configurations. Tested per IEC 60601-1, EN 12470-4, ISO 10993-5, and ISO 10993-10.

Indications for Use

Indicated for temperature monitoring in patients by qualified medical personnel. Compatible with YSI 400 series temperature measurement 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.

Predicate Devices

• YSI 400 Series Autoclavable Temperature Probe (K962070)
• GE Reusable Temperature Probes (K050837)

### Predicate Device:

YSI 400 Series Autoclavable Temperature Probe (K962070) GE Reusable Temperature Probes (K050837)

### Indications for use

Unimed Temperature Probes are intended to be used for monitoring temperature. The temperature probes are reusable and designed for use with monitors of Philips, Marquette, Mindray, Spacelabs, Siemens, Artema/S&W and other monitors compatible with YSI 400 series temperature probes.

These devices are indicated for used by qualified medical personnel only.

### Device description

Unimed Skin Temperature Probe (T2252-AS, THP-AS, TMQ-AS, TSW-AS, TSM-15AS, TSL-AS, TMR-AS), and Unimed General Purpose Temperature Probe (T2252-AG, THP-AG, TMQ-AG, TSW-AG, TSM-15AG, TSL-AG, TMR-AG) are used during patient temperature measurement. These probes consist of a connector on the monitor end and a thermistor on the patient end. These probes are to be used with YSI 400 series compatible temperature measurement systems only.

Temperature probes measure temperature by a resistor that is sensitive to temperature changes.

The probe is connected to the monitor either directly by using the connector or by an extension cable. These probes have a skin or core contact with a patient.
