PHILIPS RESPIRONICS System One BiPAP Pro Device and Accessories Analysis Report

Device Identification

The main product in the image is a positive airway pressure device used in the treatment of sleep apnea and respiratory disorders. This device is a “BiPAP” (Bilevel Positive Airway Pressure) unit. Next to the device, there is an external power adapter and connection cables. The inscription “SYSTEM ONE” is prominently embossed on the bottom left corner of the device’s casing.

Brand and Model

As a result of detailed examination, the brand and model information for the device and power adapter are as follows:

• Device Brand: PHILIPS RESPIRONICS
• Device Model: System One BiPAP Pro (The inscriptions “BiPAP Pro” and “SYSTEM ONE” are clearly legible on the front panel. Additionally, the “Bi-Flex” feature indicator is present on the panel, but the printing is partially erased.)
• Power Adapter Brand: NANOCOM
• Power Adapter Type: AC Adapter (Evaluated as an external, aftermarket/compatible part.)

Authenticity Assessment

The main device (BiPAP machine) carries the characteristic design features of the System One series, including its casing structure, button arrangement, and logo placement, making it an original Philips Respironics product. However, the accompanying power adapter (NANOCOM brand) does not belong to Philips Respironics, the device’s original brand; it is likely an aftermarket or universal adapter obtained later and compatible with the device.

Areas of Use

This device is primarily used in home care services and sleep centers. In the treatment of Obstructive Sleep Apnea (OSA), it is used to keep the airways open by providing two levels of positive airway pressure (different pressures for inhalation and exhalation) to the patient. Thanks to its BiPAP feature, it is also a suitable therapy device for patients suffering from respiratory difficulties like COPD.

Quantity Information

A total of 2 pieces of product have been identified in the image:

• 1 unit of PHILIPS RESPIRONICS BiPAP device
• 1 unit of NANOCOM brand power adapter (integrated with its cables)

General Condition and Physical Deformation

The general condition of the device has been assessed as “used”. Noteworthy details regarding its physical condition are as follows:

• Front Panel Wear: There are noticeable erasures, peelings, and abrasions on the informational texts and graphics located on the grey panel around the device’s screen (especially on the red/blue graphic strips containing “BiPAP Pro” and “Bi-Flex” texts). This suggests that the device has been used for a long time or may have been exposed to abrasive chemicals during cleaning.
• Casing: No major crack or break has been visually detected in the casing structure, but it has a cosmetically worn appearance.
• Screen Surface: Superficial scratches or stains are observed on the transparent protective plastic covering the screen.

Mechanical and Electronic Components

The navigation wheel (control knob) and the button with the triangular symbol located on the front of the device appear physically in place and intact. Since the device is not in operation (screen not on), it is not possible to draw a definitive conclusion about its electronic functions based on the visual. The power input is on the right side of the device, and the adapter is currently plugged in.

Accessories and Power Supply

The most important accessory accompanying the product is the power adapter:

• Brand/Type: NANOCOM AC ADAPTOR.
• Condition: The adapter and its cables appear relatively clean and new. A transparent packaging piece or binder is wrapped around the cables to keep them tidy.
• Compatibility: Due to it not being the original adapter, it cannot be clarified whether the technical values (Voltage/Amperage) are fully compatible with the device, as the small texts on the physical labels are not fully legible, but it is provided with the device.
• Label Information: The inscriptions “CAUTION: FOR INDOOR USE ONLY” and “MADE IN CHINA” are legible on the adapter. Additionally, safety certification logos such as CE and GS are present.

Battery Status

Devices in the System One series typically do not include an internal battery and operate with an external power source. No external battery unit is visible in the image.

Size and Portability

The device features a compact “System One” casing suitable for bedside use. It is a portable home-use medical device.

Current Faults and Potential Risks

During the visual inspection, no “current” fault that would prevent the device from operating (such as a broken casing, disconnected cable, etc.) is apparent. However, the potential risk assessment is as follows:

• The erasure of graphics on the front panel indicates that the device has been used intensively. This suggests that caution should be exercised regarding motor life and the condition of internal filters.
• The fact that the adapter supplied with the device is a “compatible” (non-original) product should be checked for voltage stability. Non-original adapters can, in the long term, damage the electronic boards of sensitive medical devices.

Conclusion and Summary

The product in the image is a cosmetically worn but structurally intact, second-hand PHILIPS RESPIRONICS System One BiPAP Pro device. It is observed that the device is paired with a compatible NANOCOM brand adapter instead of its original power supply. Apart from cosmetic wear on the screen and around the button panel, there is no major damage to the outer casing.
