Medical Diagnosis Station and Hardware Analysis Report

Device Identification

The system examined in the visuals is a combined medical measurement and data processing station mounted on a special wheeled trolley with shelves. The system consists of a monitor displaying visual data, a dedicated medical console (main unit) providing operational control, standard PC peripherals (keyboard, mouse) used for data entry, and additional hardware/storage boxes located on the lower shelves. Upon examining the button structures on the control panel (Stim, Wave, Monitor, Stop), it is understood that this device is an EMG (Electromyography) or neurophysiological test device console.

Brand and Model Information

As a result of the detailed visual inspection, it has been determined that the system is composed of components from different brands. The prominent brands and models on the system are:

• Monitor: According to the inscription on the upper left frame of the device, the monitor is a Samsung brand, SyncMaster 740n model. This model is an old-generation square-form LCD monitor.
• Keyboard: The Casper brand is legible on the wrist rest of the standard Q keyboard positioned at the front of the upper shelf.
• Printer Box: The Samsung logo and inscriptions belonging to the Samsung Printer Xpress series are clearly visible on the box located on the bottom shelf. The box features an image of the product and feature icons such as “NFC”, “ECO”.
• Medical Console Unit: The beige-colored main control panel located directly below the monitor has function buttons (Cursor, Wave, Stim Rate etc.). However, the brand or model inscription on this unit is not clear enough to be read with 100% certainty at the current visual resolution. Therefore, no estimated model has been specified to avoid being misleading.
• Mousepad: The mousepad in use features the inscription Abdi İbrahim, which appears to be a pharmaceutical or company promotion, and a partially legible product name (“…rosyn Plus…”).

Accessories and Component Count

The total components and accessories identified in the visual are:

• 1 Samsung LCD Monitor.
• 1 Beige-colored medical control panel (EMG/Neurophysiology console).
• 1 Casper brand wired keyboard.
• 1 Black optical mouse (wired).
• 1 Mousepad.
• 1 Black closed box (on the middle shelf, likely a PC case or power unit).
• 1 Samsung printer box (content status unknown, on the bottom shelf).
• 1 Mobile trolley (with blue profiles, white shelves).
• 1 Grey cable with an exposed end resting on the top surface (likely a parallel port or special device connection cable).
• 1 Metal cable holder/hanger bar (mounted on the right side).

Areas of Use

Considering specific terms on the control panel such as “Stim Rate”, “Wave”, “Cursor”, “Monitor Sweep Analysis”, this system is an EMG (Electromyography) device used in a Neurology or Physical Therapy outpatient clinic. This device is used to measure the electrical activities of muscles and nerves, aiding in the diagnosis of nerve entrapment, herniated disc, or muscle diseases.

General Condition and State

The device is generally in a “used” and “aged” condition. It appears that the system has been updated and used over time by adding different parts (e.g., Casper keyboard, Samsung monitor), rather than being a modern integrated structure. The mobile trolley (stand) appears sturdy and clean.

Physical Deformation and Cosmetic Inspection

There are noticeable signs of wear and tear on the device components due to use and age:

• Color Change (Yellowing): The rotary knobs and some button groups on the medical control panel (console) have significantly yellowed, losing their original beige/white color. This condition is the most significant sign of physical deformation, indicating that the plastic material used has been exposed to UV light and that the device’s manufacturing year is old (estimated early or mid-2000s).
• Wear: Typical signs of use are present on the keyboard and mouse surfaces. There are signs of wear on the edges of the mousepad.
• Dust and Dirt: Although the general surfaces of the device appear clean, there might be slight dust accumulation between cables and keyboard keys.

Mechanical and Electronic Component Analysis

• Wheels: The wheels of the mobile trolley are of the “lockable” (braked) type and have grey plastic bodies. They appear mechanically sound.
• Cables: A loose grey cable with an LPT or similar old-type connector end is present on the top surface of the device. The fact that this cable is not connected to anything suggests that the device is not currently ready for active use or that a part of it has been disassembled.
• Chassis Structure: No prominent large scratches or rust have been detected on the paintwork of the trolley, which consists of blue metal profiles and white shelves.
• Control Knobs: All rotary adjustment knobs (potentiometers) on the medical console are in place; no missing button caps are visible.

Screen and Label Analysis

The monitor screen is off, therefore it was not possible to analyze whether there are dead pixels or software errors on the screen. No deep scratches or cracks are visible on the screen surface.

Dimensions and Compatibility

The device is designed for adult use and has an ergonomic height that allows an operator to use it comfortably while standing or sitting on a stool. The monitor has a 17-inch standard 4:3 aspect ratio. The Samsung Printer box on the bottom shelf is of standard office printer dimensions.

Potential Failure Risk and Deficiencies

Observation: The loose grey data cable on the top panel indicates a missing connection. Furthermore, what the black unit on the middle shelf is, is not entirely clear; if it is a PC case, the ventilation clearance should be checked. The yellowing of the control panel plastics reveals the age of the device, thus the possibility that internal electronic components (capacitors etc.) may be nearing the end of their lifespan should be considered a technical risk.

However, there is no evidence in the visual, such as breaks, burn marks, or severed cables, that would definitively confirm the device is “faulty”. The device maintains its physical integrity.
