Löwenstein Medical Prisma SMART APAP Device Analysis Report

General Assessment

The device shown in the visuals is an APAP (Automatic Positive Airway Pressure) device, model Prisma SMART, from the Löwenstein Medical brand. It also includes an integrated humidifier unit, model PrismaAQUA. Such devices are primarily used in the treatment of respiratory disorders like obstructive sleep apnea. A power adapter and cable are also visible in the images along with the device.

The overall condition of the product appears to be very good and clean. The brightness of its plastic components and the absence of significant wear indicate that it has been used sparingly or well-maintained. The clarity of the logo and the inscriptions on the buttons support the originality of the product. The device consists of a total of three parts: the main unit, the humidifier unit, and the power adapter.

Area of Use and Function

The Prisma SMART is a therapy device that continuously delivers positive airway pressure to the patient’s respiratory tract during sleep to prevent breathing cessations (apnea) and constrictions (hypopnea). Thanks to its APAP mode, it can automatically adjust the pressure level throughout the night according to the patient’s needs. The PrismaAQUA humidifier unit, on the other hand, humidifies and warms the inhaled air, making the treatment more comfortable and preventing the drying of the respiratory passages.

Physical Condition and Details

• General Condition: No deep scratches, cracks, dents, or discoloration have been observed on the device’s casing. The surfaces have a clean and well-maintained appearance.
• Mechanical Components: The device’s air outlet port, humidifier chamber connection point, and control buttons are visually in perfect condition. No broken or missing parts are visible.
• Electronic Components: The device’s screen is off, so it cannot be determined whether it is working or if there are any error messages on the screen. However, there are no scratches or cracks on the screen surface. The power adapter and cable are also in good physical condition.

Accessory Analysis

The basic power adapter and cable necessary for the device’s operation are present in the visuals. No crushing, peeling, or damage has been observed on the cables. However, standard accessories for a respiratory device, such as a mask, breathing tube, and carrying bag, are not present in the visuals. The device may have various interfaces such as an SD card slot, PSG, and LAN, but these ports cannot be clearly distinguished from the visuals.

Labels and Technical Information

Technical labels containing details such as serial number, REF code, lot number, or year of manufacture, which might be found on the bottom or rear of the device, are not visible in the visuals. This information could not be accessed.

Potential Failure Risk and Conclusion

Considering the device’s external condition and cleanliness, no obvious signs of potential failure risk have been detected. Based on the evidence in the visuals, it is understood that the device has been physically well-preserved. Other than missing accessories (mask, tubing), no alarming condition has been encountered with the device itself. To determine its full functionality, the device needs to be powered on and checked.
