Dongjiang ECG-11B Electrocardiograph (ECG) Device Analysis Report

Overview and Product Description

The product shown in the images is a Dongjiang brand, model ECG-11B electrocardiograph (ECG) device. This brand and model information is clearly legible on the blue control area of the device’s front panel. The device is used to record the electrical activity of the heart to obtain an ECG output and is a medical device. Based on the details and workmanship quality in the visual, the product is assessed to be original. The device’s control panel features function keys for professional use, such as “MAN” (Manual) and “AUTO” (Automatic) modes, as well as lead selection (LEAD SELECTOR) and filtering (FILTER).

Quantity Information

The following parts have been identified in the image:

• 1 Dongjiang ECG-11B ECG main unit
• 1 patient lead cable set in a transparent bag

Physical Condition and Deformation Assessment

The device is in a generally used condition. There is significant yellowing on the plastic parts of its casing, which are understood to have been originally white, thought to be caused by time or environmental factors. This condition indicates that the device is not new. Apart from minor scuff marks due to use, no serious cracks, fractures, or dents were detected on the device’s surface. The text and symbols on the blue surface of the control panel and on the buttons are legible. The transparent cover of the paper tray is intact and in place.

Mechanical and Electronic Components

Based on visual inspection, all of the device’s buttons are physically in place, and no breaks or missing parts have been observed. The paper feed mechanism, as far as can be seen under the transparent cover, has a clean appearance, but its functionality cannot be commented on from the visual. In the upper left corner of the device, there are LED lights indicating “CHG” (Charge), an “AC”, “DC” switch, and “LINE”, “BATTERY”, “CHARGE” status. Since the device is not in operation, information about the functional status of these lights cannot be obtained.

Accessories

Included with the device is one patient lead cable set in a transparent package, which appears to be new. The colored ends of the cables are designed to facilitate correct connections. Additional accessories required for the device’s operation, such as a power cord, ECG paper, or other electrodes, are not present in the images.

It is understood from the “BATTERY” and “CHARGE” indicators on the device that it can operate with an internal battery. However, there is no externally visible battery, and an assessment of the capacity or health status of the existing internal battery cannot be made from the visual.

Label and Technical Information

The images do not include a view of the back or bottom of the device, other than the front panel. Therefore, labels containing detailed technical information such as the serial number, REF code, lot number, or year of manufacture, which are usually located in these areas, could not be accessed.

Potential Risk Assessment

The yellowing on the device’s casing indicates that the product is an older model or has been used for a long time. This situation raises the possibility that the device’s electronic components, and especially its rechargeable internal battery, may be nearing the end of their service life. The battery’s charge-holding capacity is uncertain. However, since no serious damage to the device’s casing or wear on its cables is observed, its current condition can be said to be reasonable for its age.
