AMS 8500 Patient Monitor Analysis Report

Device Description and Intended Use

The devices shown in the images are medical monitors used for patient monitoring. The “Adult Paed” inscription on the front panel of the devices indicates their suitability for use in both adult and pediatric patients. These monitors are generally used in anesthesia and intensive care units to monitor patients’ vital signs.

Brand and Model Identification

On the front panel of the devices, in the upper left and lower left corners of the screen, the brand and model information AMS 8500 is clearly visible. As a result of the analysis, it has been definitively determined that the brand of the product is AMS and the model is 8500.

Quantity Information

A total of 3 units of AMS 8500 patient monitors are present in the images. No additional accessories or parts are shown in the visuals.

General Condition and Assessment

All three devices are in used condition. The casings of the devices show various signs of wear and tear due to prolonged use. Since the screens are off, no comment can be made regarding their operational status, but they appear physically intact.

Physical Examination

Upon physical examination of the devices, the following details were observed:

• Casing: The white casings of the devices generally show dirt, stains, and scratches. Especially on the side of the top device, paint chips and noticeable yellowing are visible.
• Screen: The monitors’ screens are off. No cracks or deep scratches were observed on their surfaces, but they have a slightly dusty and stained appearance.
• Buttons and Controls: The control buttons and rotary potentiometers on the front panel are physically in place. However, the rotary control knob on the bottom-right device has a different design compared to the other two devices.

Battery Status

A yellow sticky note attached to one of the devices bears the handwritten phrase “No Battery”. This note clearly indicates that the devices do not have internal batteries or that any existing ones are non-functional. The battery status icons on the front panels suggest that the devices can normally operate with batteries, but currently, they do not have them.

Label and Date Information

On the side of the device located at the bottom-left, there is a green label. The readable information on this label is as follows:

• Code: 150801600
• Dates: 08.2014, 08.2016, 08.2017

These dates are likely part of a calibration or maintenance label. No other label indicating a serial number or year of manufacture could be identified in the images.

Accessories and Missing Parts

No power cables, patient connection probes (ECG, SpO2, etc.), or other accessories belonging to the devices are present in the images. The devices are only available as main units, indicating that additional parts must be supplied for their use.

Potential Risk Assessment

The used condition of the products and their cosmetic imperfections (scratches, stains, paint chips) indicate normal, acceptable wear and tear. The most significant deficiencies are the absence of batteries and any accessories for the devices. This situation indicates that the devices cannot be tested or used in their current state. To make them functional, batteries and all necessary sensor cables must be supplied separately. No comment can be made regarding the functionality of the devices based on the visuals alone.
