ShenDa YG-250 Medical Cold Light Source Analysis Report
Device Identification and Information
The device analyzed in the images is a cold light source (Medical Cold Light Source) unit used for medical purposes, providing illumination in surgical and diagnostic procedures. The device’s design features a manually controlled structure providing dual light output.
Brand and Model: The logo and model labels on the product have been clearly examined, and the device’s brand has been identified as ShenDa, with the model being YG-250. The front panel features the English inscription “MEDICAL COLD LIGHT SOURCE YG-250”.
Manufacturer Information: In addition to the “ShenDa” logo on the device’s front panel, the bottom section contains Chinese characters indicating the full name of the manufacturing company, followed by phrases denoting a limited liability company (Co., Ltd.).
Physical Condition and Assessment
General Cosmetic Condition: The device appears to be in “Used” condition. Typical yellowing (discoloration) has been observed on the front panel’s plastic, which is likely due to the manufacturing date and ambient light exposure. No significant rust, deep scratches, or dents have been detected on the device’s metal casing.
Deformation Check: The product’s casing maintains its integrity. No cracks or fractures are present at the corners or seams. The labels and inscriptions on the front panel are not faded and remain legible.
Technical Interface and Control Mechanisms
The front face of the device features the following components that provide operational control:
- Power Switch: On the left side, there is a green, presumably illuminated power switch (ON/OFF – 0/1). The switch appears physically in place and intact.
- Light Output Ports: The device has two circular light output sockets. These ports are designed for fiber optic cable connections.
- Intensity Adjustment Knobs: Around both light output ports, there are rotary control knobs used to adjust the light intensity. The knobs feature the word “OUTPUT” and icons symbolizing increasing light level (from a small sun to a large sun). The mechanical structure of the knobs appears robust visually.
- Toggle Button: Between the two large adjustment knobs, there is a small, blue/gray square button with Chinese characters and a schematic symbol, which allows switching between light channels.
- Warning Signs: The panel displays an exclamation mark symbol meaning “Caution” and a human figure symbol within a box, indicating a Type BF device (Type BF Applied Part).
Areas of Use and Compatibility
Intended Use: This device is used to transmit high-intensity cold light via a fiber optic cable to the tip of a telescope or endoscope during endoscopic surgical procedures (laparoscopy, arthroscopy, etc.) and diagnostic examinations.
Compatibility: The port structures on the device’s front face appear compatible with standard fiber optic light cables. Its dual output capability offers redundant operation or quick switching for different instruments.
Quantity and Accessory Information
The images show only 1 unit of the main device (cold light source). External accessories such as a power cable, fiber optic cables, or a user manual are not present in the visuals.
Potential Malfunction and Risk Analysis
Based on visual inspections, there are no indications of casing-related malfunctions (such as breakage, missing parts, etc.) on the device. However, the following points should be considered:
- Bulb Lifespan: Devices of this type typically use halogen or similar bulb technology. Since the device is used, the lifespan of the internal light source (bulb) cannot be determined from the visuals and may require replacement.
- Fan and Ventilation: The condition of the cooling system cannot be ascertained from the visuals, but no dirt accumulation indicating blockages in these areas has been observed on the outer casing.
Label and Certification Details
The data read from the product are as follows:
- Logo: ShenDa
- Model Code: YG-250
- Device Description: MEDICAL COLD LIGHT SOURCE
- Safety Class: Type BF (Electrical safety standard for parts in contact with the body)
Conclusion and Summary
The ShenDa YG-250 Medical Cold Light Source is a complete device that shows normal age-related wear (discoloration/yellowing) aesthetically but has full structural integrity. The control knobs and input ports are physically sound. The fiber optic cable and power cable, which are necessary for the device’s functionality, are missing. It is assessed to be intended for use as a light source unit in endoscopic systems.
