Philips Respironics Dorma 500 Auto CPAP Device Analysis Report

Device Identification

The device in the image is an automatic pressure-adjustable PAP (Positive Airway Pressure) device used in respiratory therapy and the treatment of sleep disorders. The design of the device, the air tube connection, and its position within the carrying case confirm that it is a home-use medical support product.

Brand and Model

As a result of detailed visual inspection and expert confirmation, the brand and model information of the product is as follows:

• Brand: Philips Respironics (The “Dorma” series on the device is manufactured by Philips Respironics.)
• Model: Dorma 500 Auto
• Model Type: Auto CPAP (Automatic CPAP)

The phrase “Dorma 500 Auto” is clearly and legibly located on the upper right corner of the device’s front panel. Furthermore, this model information is confirmed by the “AUTO CPAP” inscription on the yellow label subsequently added to the device.

Areas of Use

This device is primarily designed for use in the treatment of Obstructive Sleep Apnea Syndrome (OSAS). It delivers continuous or variable positive airway pressure to prevent the patient’s airway from collapsing during sleep. Thanks to its “Auto” feature, it can automatically adjust the pressure according to the patient’s needs. It is suitable for individual use in hospitals and, more commonly, in home care services.

Originality

The product’s casing structure, color tone, font quality of the “Dorma 500 Auto” print, and material craftsmanship indicate that the device is an original Philips Respironics product. There is no visual evidence to suggest it is an aftermarket or replica product.

Quantity Information

The product and accessories visible in the image and subject to analysis are as follows:

• 1 Main Device (Dorma 500 Auto)
• 1 Air Tube (Spiral structure)
• 1 Tube Connection Elbow (Swivel adapter)
• 1 Original Carrying Bag (Black)

In total, there is 1 device and its basic accessories as a set.

General Condition

The device is understood to be in second-hand (used) condition. The layer of dust accumulated on its casing and sticky residues indicate that the device may have been stored for some time or has been in active use. Slight wear due to use can be observed on the inner surface of the black carrying bag.

Physical Deformations

• Casing: The black plastic top surface of the device shows heavy dust accumulation. No serious cracks, fractures, or dents were detected visually, but the surface needs cleaning.
• Surface Stains: There are adhesive-like marks or peeled tape residues to the left of the “Dorma” inscription and around the hose outlet.

Accessories and Connections

Tube (Circuit): A gray, spiral-structured CPAP tube is connected to the device. The elbow connection (swivel) of the tube is attached to the device’s air outlet. While the structural integrity of the tube appears sound in the image, it may require replacement for hygienic reasons as it has been used.

Bag: The device is housed in its dedicated black, zippered carrying bag with protective foam support. The inner mesh sections of the bag appear intact.

Label Information

In addition to the factory prints, there is a yellow label with handwritten notes subsequently affixed to the device. The following phrases are legible on this label:

• “350 /” (Likely an inventory code, old price, or tracking number)
• “AUTO”
• “CPAP”

These handwritten notes further confirm the technical type of the device (Automatic CPAP).

Mechanical and Electronic Components

Screen: The screen located on the device’s top panel is in the off position, thus no comments can be made regarding pixel errors or screen functionalities based on the image.

Air Outlet: No breaks or deformations are observed in the air outlet port; the tube adapter is fully seated in the port.

Potential Malfunction Risk

No major damage (broken casing, severed cable, etc.) that would prevent the device from operating is visible in the images. Its physical condition is sound. However, as it is a medical respiratory device, and given the dust accumulation seen in the image, it is recommended that filter checks, detailed cleaning and sterilization, and a calibration test be performed before use.
