Mindray will not be liable for damage caused by other solutions. If you have any questions, please contact Mindray Customer Service Department or sales representative. 10. Before introducing the transducer: do not rub or spray the tip of the transducer with an anesthetic agent.
Use the P7-3Ts transducer under the following ambient conditions: ambient temperature: 0°C to 40°C relative humidity: 30% to 85% (no condensation) atmospheric pressure: 700 hPa to 1060 hPa 3. Repeated disinfection will eventually damage the transducer, please check the transducer’s performance periodically.

Label Meaning Indicates safety precautions. The label uses the same signal words as used in the descriptions in the operator’s manual.
2. The TE transducer is intended to be used on adults only. Fetal imaging and pediatric imaging is not permitted. The P7-3Ts transducer is designed for 2D, M Mode, color Doppler (Color), pulsed wave (PW) Doppler, and continuous wave (CW) Doppler by applying ultrasound energy through the esophagus or stomach of the patient into the heart.
Perform tip deflection inspection. See “2.1.2.1 Tip Deflection Control”. Perform brake inspection. See “2.1.2.2 Brake Operation”. Perform scanplane rotation inspection. See “2.1.2.5 Scanplane Rotation Inspection”. Perform leakage test. See “2.3 Electrical Safety”. Contact Mindray or your local representative immediately to report any damage or discrepancies.
Structure of P7-3Ts P7-3Ts is a phased array transducer, mounted in a sealed tip at the end of a gastroscope. The transducer is intended for imaging of the heart through the esophagus and the stomach.

Overview Name Function Transmits electrical signals between the transducer body and Cable connector. Connector Connects the transducer to the ultrasonic diagnostic system.
The mechanical operation and physical integrity of the transducer should be checked after taking it out of the box and prior to each exam. If any abnormality is found, immediately stop using the transducer and contact MINDRAY Customer Service Department or sales representative.
Transducer Controls and Inspection 2.1.2 Deflection and Scanplane Rotation Control The control handle is designed for one-hand operation. Normally the operator takes the control handle in his left hand. Thumb, first and second fingers control the deflection control wheels and scan plane rotation push-buttons. The smallest wheel on the handle is for controlling the transducer left/right tip deflection.
Page 21
Transducer Controls and Inspection 1. Check if the maximum deflection of the tip is 90° to 120° WARNING: upward, 60° to 90° downwards and 30° to 45° left/right. If the deflection shows an unwanted amount of free play or exceeds the maximal deflection angles given above, do not use the transducer.
Page 22
Transducer Controls and Inspection Unlock-white Left/right Lock-red 1. Confirm the brake is in the unlocked position. 2. Deflect the tip to the anterior direction. 3. Move the brake to the locked position. 4. Confirm that the tip is locked in the deflected position. 5.

Transducer Controls and Inspection other. As shown in figure below, a 180°rotation of the scanplane fills all four quadrants of the conic imaging volume. The direction of the tip of the endoscope is easily steered using the deflection control wheels on the handle of the instrument to allow exact positioning of the transducer in the esophagus.
Connecting and Disconnecting the Transducer This transducer should be used only with Mindray compatible ultrasonic diagnostic systems. Before connecting or disconnecting a transducer, freeze or turn off the NOTE: ultrasonic diagnostic system, otherwise the ultrasonic diagnostic system or the transducer may malfunction.
2.3.1 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-Part1.General Requirements for Safety. To maintain patient safety it is important to have a low electrical leakage current in the product.
Transducer Controls and Inspection 2.3.2 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.
Thermal Safety Maintaining a safe thermal environment for the patient has been a design priority at Mindray. It is generally agreed that to avoid damage to body tissues, for long term exposures, tissue contact transducer tip temperatures should be less than 43°C. The ultrasound system...
Transducer Controls and Inspection The system has a lower thermal limit of 17.5°C. If the temperature of the transducer tip reaches 17.5°C, the temperature display turns red. To avoid the risk of esophageal burn for adult patients, reduce WARNING: the time spent imaging at distal tip temperatures in excess of 42°C (107.6°F).
7. 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. Cleaning and Disinfecting the Transducer and Bite-guard For cleaning and disinfecting the transducer, please refer to “4 Cleaning and Disinfection”...

Transducer Controls and Inspection transducer temperature sensor is activated, and the transducer temperature is displayed, indicating the transducer is ready for use. If the calibration test of the transducer fails, (no response from the scanplane buttons after calibration), re-connect the transducer to repeat the calibration test. 3.
3. To avoid injury to the patient, if during the deflection test, a sharp “U-turn” of the transducer tip is observed (the transducer tip angle exceeds the maximum deflection angles), do not use the transducer. Call Mindray or your local representative. 4. Some gels and sterilants can cause an allergic reaction in...
Examination Couple Gel, Sheath, and Bite-guard 3.2.1 Couple Gel Apply a sufficient amount of water-soluble acoustic coupling gel on the transducer acoustic window. Only use water-soluble acoustic coupling gel. Other coupling CAUTION: gels containing ingredients like ethanol, mineral oil, Iodine, lotions, lanolin, aloe vera or methyl or ethyl parabenzoic acid can cause transducer damage.

To fax orders call: 1-319-656-4451 For details, please contact your local Mindray representative for assistance. Examination The operator should adopt proper ultrasonic scanning procedures and methods according to different target organs.
Examination 3.3.1 Cautions The actual techniques for introduction of the TE transducer into the patient are beyond the scope of the user guide. There are numerous medical texts and articles which thoroughly address this topic. Observe the following precautionary measures when conducting an exam. Maintenance of an unobstructed airway is a prime consideration for all patients.
Examination There are two wheels for controlling the transducer tip deflection. The wheels have brake and freely-moving modes. In the braked mode, the movement of the deflection wheel is restrained. This is used to hold the tip in a certain position. Special care should be taken when inserting and removing the transducer.

Examination Test Step: 1. Place the probe head gently on the acoustic window of the phantom which is covered by water or gel, and make sure the axial resolution targets are displayed in the center of the image. 2. Adjust the Focus to the axial resolution target group. 3.
Examination Adjust display depth, to make horizontal groups display in the image. Adjust the Focus to be in horizontal groups (no explicit standard). Adjust gain, TGC and etc. to make horizontal groups display clearly. Use caliper to measure horizontal target distance by step of 20mm. For all measurement data, value with a maximum deviation to 20mm should be in the range of 19.4mm-20.6mm.
