Physical Deformation
There is noticeable dirt and yellowing on the white plastic casing of the device, especially around the keypad and the paper slot cover. The text on the keypad is legible. No deep scratches or cracks have been observed on the screen glass. The zipper and fabric of the carrying case appear to be in good condition.
Mechanical Components
The paper slot cover of the device is in the closed position. The keys are in place. The patient cable socket input is visible on the side of the device and appears clean. The spring mechanisms of the limb clamps and the rubber parts of the chest suction bulbs appear to maintain their integrity as far as can be understood from the image.
Electronic Components
The device’s screen is off; therefore, there is no visual data regarding its electronic functionality. The socket of the patient cable on the device side and the electrode connection tips appear to be intact. No significant tearing or exposed wire has been observed in the cable insulation.
Accessories
The accessories provided with the device are as follows:
- 1 ECG patient cable (with Tsingtao Bright brand socket)
- 4 colored limb clamp electrodes
- 6 chest suction bulbs (vacuum electrodes)
- 1 black carrying case
There is no expiration date information on the accessories. The power cable of the device is not included in the images.
Battery Status
It cannot be determined from the image whether the device has an internal battery. The rear label contains DC 14.4V voltage information, which may indicate a battery power supply, but there is no information regarding the physical condition of the battery (swelling, leakage, etc.).
Label Information
The following information is provided on the label on the rear surface of the device:
- Model: CM300
- Serial Number (SN): 30080603046
- Manufacturing Date: 2008.10.26
- Supply Voltage (AC): AC 110V/220V
- Supply Voltage (DC): DC 14.4V
- Frequency: 50Hz/60Hz
- Power: 35VA
- Manufacturer: Shenzhen Comen Medical Instrument Co., Ltd.
- CE Mark: CE 0434
Additionally, there is an “AC220V” warning label on the rear casing of the device.
Screen Analysis
The device’s screen is off. There is no text, warning, or menu display on the screen.
Dimensions and Compatibility
There is no information in the image regarding the physical dimensions of the device. The patient cable and electrodes appear to be compatible for standard adult use.
Manufacturing Year
According to the information on the rear label of the device, the manufacturing date is October 26, 2008.
Documents
There are no documents such as an invoice, warranty certificate, or user manual in the images.
Usage Duration
There is no information on the screen or label regarding the total usage hours or duration of the device.
Existing Faults
There is no clear evidence in the images, such as broken parts or error messages, that the device is faulty. However, it could not be determined whether the device is in working condition because it is turned off.
Potential Fault Risk
Considering that the device was manufactured in 2008 and is in a used condition, it is highly likely that its internal battery (if present) has reached the end of its service life. There is a risk of contact failure over time at the connection points of the patient cable and electrodes. The general condition of the device shows normal signs of wear for its age.
