Intended Use

THE CSZ SKIN TEMPERATURE SENSOR is intended for use in routine continuous monitoring of skin temperature when the other sensors which might better reflect core body temperature are not clinically indicated. The sensor is designed for placement on the surface of the skin. THE CSZ TYMPANIC TEMPERATURE SENSOR is intended for use in routine continuous monitoring of the tympanic temperature as an indicator of the core body temperature when this type of measurement is clinically indicated. The probe is designed for placement inside the ear canal. All probes are intended for use by qualified medical professions only.

Device Story

Disposable temperature sensors utilize resistance-based thermistor chips (400 series) to detect temperature changes; sensors encapsulated in PVC cups; skin sensors feature foam enclosures for insulation; tympanic probes feature foam tips for atraumatic insertion and compressible foam cylinders for securement. Probes connect via Molex or phone connectors to instrument cables, which interface with multi-channel patient monitors. Used in clinical settings by medical professionals for continuous monitoring of hypo/hyperthermia. Output is a temperature reading displayed on a compatible monitor, assisting clinicians in patient thermal management.

Clinical Evidence

Bench testing only. No clinical data presented. Testing included thermistor resistance/temperature curve accuracy, current leakage (IEC 60601-1), biocompatibility (ISO 10993), and performance per EN12470-4.

Technological Characteristics

Disposable thermistor-based temperature sensors (400 series). Materials include PVC encapsulation and foam insulation. Connectivity via Molex or phone connectors to standard multi-channel patient monitors. Sterilized via ethylene oxide. Complies with IEC 60601-1, IEC 60601-2-49, and EN12470-4 standards.

Indications for Use

Indicated for routine continuous monitoring of skin or tympanic temperature in patients requiring temperature assessment. Tympanic sensors serve as indicators of core body temperature. Intended for use by qualified medical professionals only.

Regulatory Classification

Identification

### A DESCRIPTION OF THE DEVICE 807.92 (A) (4)

K070339

Page 2

Undesirable effects of hypothermia and hyperthermia are clinically well documented. Malignant hyperthermia is every doctor's nightmare. To detect hypo/hyperthermia, the body temperature is continuously monitored using disposable temperature sensors or probes. The basic component of these sensors is a resistance chip, which is sensitive to changes in temperature. The chip is in the form of "400" series thermistor connected to a lead wire and encapsulated in a PVC cup. At the end of the lead wires an insert molded connector or standard phone connector provides for the interconnection with the instrument cable.

These sensors are inserted in the structure that fits specific anatomy where the temperature is measured.

The skin sensor is placed on the surface of the skin and is a part of the foam enclosure which provides thermal insulation for more accurate temperature mcasurement.

The tympanic probe is designed for placement in proximity to the tympanic membrane, The probe incorporates a small foam tip for atraumatic insertion and a large compressible foam cylinder for securement and thermal insulation.

The distal end of the skin sensor and the tympanic sensor is terminated with a Molex or phone connector for interconnection with the instrument cable.

The probes are individually packaged in sterilizable bags. There are 20 probes per box and 10 boxes per shipping carton. Probes are ethylene oxide sterilized.

The following probes and cables are included in this 510k application:

Probes:

Skin Temperature Sensor (487M, 499B) Tympanic Temperature Sensor (495M, 495M-P) Cables (4872MS, 4872ML, 4900B)

These probes can be used with Smith's Level 1 TM-200 temperature/monitors or any other multi-channel patient monitor compatible with the "400" series thermistors or equivalent.

The packaging label describes: the product name, catalog number, expiration date, CE mark, legal entity information and the caution: Federal (USA) law restricts this device to sale by or on the order of a physician.
