Page 28: Electrical Safety
Transducer Controls and Inspection Electrical Safety The electrical leakage current test should be performed on the TEE transducer after taking it out of the box and prior to each exam, alternatively, if the bite-guard inspection test is done prior to each exam, then the electrical leakage current test should be done yearly at a minimum. 3.3.1 Electrical Leakage Current Test Mindray ultrasound systems with accessories are designed to meet the requirements for patient safety described in IEC 60601-1 Medical Electrical Equipment-Part 1. General Requirements for Safety. To maintain patient safety it is important to have a low electrical leakage current in the product. The endoscope shaft has no electrically conducting surfaces, and is covered with a layer of material, which permits neither fluids nor electricity to pass through it. Electrical safety is maintained for the transducer by keeping this material intact. Each TEE transducer is tested for electrical isolation and leakage current before it is shipped to a customer. WARNING ● To avoid injury to the patient, do not use the transducer if the insulating material has been punctured or otherwise compromised. -
Page 29: Bite-Hole Inspection Test
Transducer Controls and Inspection 3.3.2 Bite-hole Inspection Test Bite-holes or other damages of the endoscope surface can alternatively be detected by a simplified test without the access to the ultrasound system, by using the following procedure. The objective of this test is to detect bite-holes. It is safe and easy to perform, but is not an isolation or leakage current test as described in EN 60601-1. The test equipment is shown in figure below. -

Page 31: Control Settings, Temperature
The temperature measurement function should be verified to the specifications at least once a year. Test Setup Assemble the following items for the test. Temperature stabilized water bath • Temperature gauge with accuracy of ± 0.1°C • Temperature Calibration Test Adjust the water bath temperature to 41°±0.1°C and monitor the temperature with the gauge. If an accurate and stable water bath is not available, the added inaccuracy must be taken into account when the temperature is read from the ultrasound system. Deviation of more than ±0.5°C is not acceptable. Maintaining this accuracy without temperature regulation may be difficult. Connect the TEE transducer to the ultrasound system. Press <Freeze> and set patient temperature to be 41°C on ultrasound system. Put the transducer tip in the water bath. At least 10 cm of the distal end must be submerged. Observe the temperature indicated on the system monitor. Wait until the temperature display is stabilized at 41°±0.5°C plus/minus any water bath temperature deviation. Observe that the Warning pop-up window is displayed. If both steps 6 and 7 are passed the temperature shutdown works as stated. If not, Contact Mindray or your local representative.

There are numerous medical texts and articles which thoroughly address this topic. Observe the following precautionary measures when conducting an exam. -
Page 36: Operation Of Deflection Controls
Examination In consideration of the above 2 points, the user should freeze the image, which turns • the power to the transducer off, and allow the endoscope deflection controls to be disengaged whenever active scanning is not desired. Proper patient preparation is essential for successful examinations. This includes • restrictions on food and liquid intake as well as a thorough explanation of the examination procedure and other instructions as the particular situation warrants. -
Page 37: Emergency Retraction
Examination CAUTION To avoid damaging the transducer, do not deflect the distal tip of the transducer by direct application of force. Use the deflection wheels for this task. 4.3.3 Emergency Retraction If the transducer tip should get jammed in a deflected position inside the patient, and all attempts to release the deflected tip should fail, follow the following procedure to assure a safe retraction of the transducer. Disconnect the transducer from the ultrasound system. At an accessible location between the transducer handle and the patient, cut the entire endoscope shaft, including all internal wiring, using heavy duty cutting pliers or another suitable tool. The deflection mechanism is now released and the transducer may be safely retracted. After Examinations After the examination is completed, turn OFF the ultrasonic diagnostic system, remove the bite-guard and disconnect the transducer, and then clean and disinfect the transducer. - Page 38 This page intentionally left blank.
