What Is the Siemens/Draeger 5204669 Compatible Skin Temperature Probe?

The Siemens/Draeger 5204669 compatible skin temperature probe is a reusable, aftermarket probe for continuous skin surface temperature monitoring in adult patients. It rests against the skin, usually taped over the torso or another consistent site, and sends a resistance signal back to the monitor, which displays it as a temperature reading in °F or °C. Skin temperature is commonly tracked alongside core temperature during surgery, in the ICU, and during warming or cooling therapy. It is a compatible replacement, not an original Siemens or Draeger part, and it is built to the same fit, form, and function as the OEM 5204669 probe.

Compatible Monitor Models

This compatible probe is confirmed for use with the Draeger Infinity Delta, Infinity Gamma, Infinity Kappa, and Infinity Vista patient monitors, which share the keyed round 7-pin temperature input. It is also listed for use with the Contec MS400 patient simulator, which is useful when biomedical technicians verify temperature channels during preventive maintenance. Temperature probes built for other monitor brands use different connectors and sensor characteristics, so use this probe only with the models listed.

Design and Construction

The probe has a flat 0.35 in (9.0 mm) sensor disc that sits flush against the skin for good thermal contact and secures easily with medical tape or an adhesive cover. The 9.8 ft (3.0 m) gray cable reaches from bedside or OR monitors without an extension, and the round 7-pin connector is keyed so it seats only in the correct orientation. The probe is latex-free, non-sterile, reusable after cleaning and disinfection according to facility protocol, weighs about 0.3 lbs, and ships one per bag.

When to Replace Your Draeger Skin Temperature Probe

Skin probes see constant handling, taping, and cleaning, which wear the sensor disc and cable over time. Replace the probe when readings drift, fluctuate, or disagree with a reference measurement, when the monitor reports “probe off” or out-of-range messages with the probe properly applied, or when you see a cracked or separated sensor disc, a damaged cable jacket near the disc or connector, or bent or corroded connector pins. Testing against a temperature simulator or a known-good probe quickly confirms whether the probe is at fault.

Cross Reference and Interchange Part Numbers

This compatible adult skin temperature probe, IPR Medical SKU TS-DG-AS30, cross-references to Siemens part number 5204669, to Draeger part number 4329822 E530U, and to Unimed part number TSM-AS. Materials managers and purchasing staff can use any of these numbers to confirm the match against existing inventory, work orders, or requisitions. For core temperature monitoring on the same monitors, IPR Medical also stocks the compatible Siemens/Draeger 5204644 adult oral/rectal probe.
