The customer reported that the probe tip of their braun pro6000 overheated and burned patient¿s ear canal.The reported burn was noted to be a surface burn to the patient's inner ear.Details of medical intervention were requested but not provided.The thermoscan pro 6000 ear thermometer is indicated for the intermittent measurement of human body temperature for patients having ages ranging from normal weight (full-term) newborn to geriatric adults in a professional use environment.The probe cover is used as a sanitary barrier between the infrared thermometer and the ear canal.The pro 6000 technology reads the infrared energy emitted by the tympanic membrane and surrounding tissues to determine the patient¿s temperature.To help ensure accurate temperature measurements, the sensor itself is warmed to a temperature close to that of the human body.When the thermoscan is placed in the ear, it continuously monitors the infrared energy until a temperature equilibrium has been reached and accurate measurement can be taken.An inspection of the device by the facility after its use for the measurement found a crack in the device's sensor tip.The device's ifu states if the probe lens window is damaged return to hillrom/welch allyn for service.A surface/superficial /first-degree burn injures the top layer of skin (epidermis) and causes the tissue below the skin (dermis) to become red and swollen.These minor burns will usually heal without further treatment.First-degree burn are considered as a minor burn unless it involves substantial portions of the hands, feet, face, groin, buttocks, or a major joint.Hillrom/welch allyn¿s investigation of pro 6000 ¿hot tip¿ complaints confirmed that aggressive cleaning and decontamination practices can cause liquid ingress.Consequently, liquid ingress can adversely affect the temperature sensor causing the pro 6000 device to behave inconsistently and to overheat the speculum tip.It is believed that replication of the malfunction with the returned devices from the customer at the manufacturing site has not been possible as any fluid that may have ingressed had likely evaporated, therefore not showing the ¿hot tip¿ malfunction.Although this reported event did not result in serious injury, based on hillrom¿s ability to replicate the malfunction of a ¿hot tip¿ on new devices, that can exceed a safe temperature threshold and cause a more serious injury, we have deemed this complaint reportable.
