Product description IR thermometers consist of an IR probe, electronic circuitry, a microprocessor, and an LCD or LED display. There are two types of IR thermometry: ear and skin. Ear temperatures can be measured either at the TM or at the walls of the inner ear canal. In tympanic thermometry, the temperature of the TM and its surrounding tissues is measured directly. IR skin thermometry is used to estimate the temperature of a site on the skin (e.g., axilla, forehead). Some units may include rechargeable batteries, built- in timers for measuring pulses and respiration rates, designs for use with neonates, and user-replaceable probes. Calibration- checking devices may also be available. Use and maintenance User(s): Physicians; nurses; other medical staff Principles of operation Maintenance: Medical staff; technician; Probes are made up of electronic thermal radiation transducers biomedical engineering staff and/or service and waveguides. The radiation collected by the waveguide is contract with the manufacturer or third-party converted to an electrical signal by the transducer and displayed organization as a temperature reading. The transducer is either pyroelectric or Training: Initial training by manufacturer, Hospital medical equipment - general information a thermopile sensor. A pyroelectric sensor measures the average operator’s manuals, user’s guide temperature of the tissue within its field of view. It must be used with a shutter mechanism to provide a controlled period of Environment of use exposure to the tissue’s IR emission. A thermopile sensor allows Settings of use: Hospital; clinic; physician continuous readings and thereby facilitates scanning for the office 2012 highest temperature. Requirements: NA (battery-operated handheld devices do not have special settings Operating steps requirements) • Place disposable cover over temperature probe. • Insert the probe into the ear canal or place probe on the Product specifications skin. Approx. dimensions (mm): 125 x 60 x 50 • Wait a few seconds until a measurement is taken. Approx. weight (kg): 0.075 Reported problems Consumables: Probe covers The most common problem with ear thermometers is inaccurate Price range (USD): 13-900 (150 typical), 2.50-5 and inconsistent measurements. Inconsistent technique can for 100 probe covers; price covers all types and lead to contradictory temperature readings. Earwax and skin/oil variations buildup on the probe can lead to inaccuracy. Poor penetration, Typical product life time: 8 years improper aiming, or obstruction will result in significantly Shelf life (consumables): Variable lowered readings. Many malfunctions result from thermometers being dropped. Types and variations • Ear • Skin © Copyright ECRI Institute 2012 (not including GMDN codes and device names).
