Hoffrichter Trend 500 Respiratory Device Analysis Report
Product Description and Contents
The visuals show a respiratory support device, model Trend 500, from the Hoffrichter brand. The rear label of the device states “BI-LEVEL ST33,” indicating that it is a PAP device operating in Bi-Level S/T modes. Such devices are used in the treatment of conditions like respiratory failure or sleep apnea. The visuals display a total of two product parts: the main unit and one DC power cable with a cigarette lighter input.
General Condition and Physical Deformation
The device is generally in “used” condition. No prominent cracks, fractures, or dents were observed on the casing. However, there are light scratches, stains, and some dust in various places on the surface. Specifically, dust accumulation is present between the ventilation grilles on the rear side. No noticeable fading in the device’s colors was observed. The screen and control buttons on the front panel appear physically intact. The red security sticker on the back of the device is in place but has slightly lifted from one edge.
Mechanical and Electronic Components
Upon visual inspection of the device’s plastic casing, buttons, front air outlet port, and rear ventilation grilles, no mechanical breakage or damage was detected. Regarding electronic components, the rear panel features a standard AC power input, a DC power input, and a multi-pin socket labeled “REMOTE/ANALOG.” All these sockets are in good physical condition. As the device is not shown operating in the visuals, no comment can be made regarding the functionality of the LCD screen or the electronic circuits.
Technical Details and Label Information
The following technical information was obtained from the label located on the rear panel of the device:
- Brand: Hoffrichter
- Model: Trend 500
- Device Type: BI-LEVEL ST33
- Power Requirement: 100-240V, 50-60 Hz, 1.2A
- Manufacturer Information: Hoffrichter GmbH, Schwerin, Germany
- Certification: CE 0123 mark is present.
Details such as the serial number and year of manufacture on the label are not clearly legible in the visuals. No information regarding lot or REF codes was found either.
Accessories and Missing Parts
Only one DC power cable compatible with a car cigarette lighter is included with the device in the visuals. Essential accessories required for the device’s operation, such as the standard AC power cable, breathing circuit (hose), and patient mask, are not present.
Potential Risk Assessment
Although the product appears to be in good physical condition, due to its used state and the presence of dust, it may require detailed technical maintenance and hygienic cleaning before use. It cannot be determined from the visuals whether the device is in working order. The absence of essential accessories (AC power cable, hose, mask) indicates that the device is not ready for immediate use. Apart from this, no alarming damage was observed on the casing or connection ports.
