Hitachi EUB-305 Ultrasound Device Analysis Report

General Overview and Device Identification

The images show a medical imaging device mounted on a wheeled stand and a probe belonging to this device. The structure of the control panel and monitor indicates that it is an ultrasonography device. The product is designed for performing diagnostic medical imaging. In total, the images contain 1 ultrasound main unit, 1 wheeled transport stand (trolley), and 1 ultrasound probe.

Brand and Model Information

The brand and model of the device in the image have been clearly identified. Based on the quality of its logo and labels, the authenticity of the device is assessed to be original with a high probability.

• Ultrasound Device Brand-Model: Hitachi EUB-305
• Probe Brand-Model: Hitachi EZU-PL21

Physical Condition and Deformation Analysis

The device is generally in a used condition. There is significant yellowing on the plastic components, such as the control panel, probe, and probe holder, which has occurred over time. This situation indicates that the device is an older model and has been in use for a long period. No cracks, fractures, or serious dents have been observed on the main casing or the monitor. Minor scratches, which may have resulted from use, and general soiling are visible on the surfaces. Discoloration and stains are noticeable on the probe holder and the surrounding area.

Mechanical and Electronic Components Inspection

The mechanical parts of the device, including the wheels, the buttons on the control panel, the sliders, and the rotary control knob, appear visually complete and undamaged. The functionality of the buttons or sliders cannot be commented on from the visual inspection. Electronically, the device is observed to have a CRT (cathode-ray tube) monitor. The monitor is turned off, so no assessment can be made regarding its operational status or image quality. The device’s power button has “ON” and “OFF” positions and appears physically sound.

Accessories and Connection Ports

The primary accessory included with the device is an ultrasound probe labeled “Hitachi EZU-PL21”. The probe’s cable is connected to the device, and there are no visible breaks or crushes in the cable. On the side of the device, there is a connection socket for the probe. This socket features one circular connector port and another, different type of connector, marked with “SECTOR PROBE” and “LINEAR” labels. Furthermore, the stand includes a dedicated holder compartment designed for the probe and gel.

Labels and Technical Information

The following information is legible on the device’s labels. Information such as a serial number or REF code has not been found on the labels.

• Probe Model and Frequency: EZU-PL21 3.5MHz
• Side Panel Warning Label: There is an English warning text stating that the transducer cable should not be connected or disconnected while the device is in operation and that the cable should not be bent.

Potential Risk Assessment

The yellowing observed on the plastic components, due to the device’s age, indicates material degradation over time. Other than this, no obvious risk factors requiring immediate intervention, such as severe cable crushing, a cracked casing, or rust, have been observed. The overall structure of the device appears solid. However, as with any old electronic device, there could be potential failure risks in the internal electronic components (especially the CRT monitor and power circuits) if it has been unused for a long period or simply due to its age. Based on the visual inspection, the device’s current condition is considered appropriate for its age.
