Löwenstein Medical LUISA Ventilator Analysis Report

Device Identification and Brand Model

The product in the images is a medical device. According to the label on the bottom of the device, the brand is Löwenstein Medical Technology and the model is LUISA. A variant code stated as WM 150 TD is also present on the label. The device’s workmanship, label quality, and overall appearance give the impression of being a genuine product.

This device is a portable ventilator used for providing respiratory support. The ports on it indicate that it also supports oxygen saturation (SpO₂), carbon dioxide (CO₂) monitoring, and nebulizer (Neb) functions.

Quantity and General Condition

There is one ventilator device in the images. No accessories (power cable, tubing, sensors, etc.) are visible next to or in the box with the device.

The device is generally in very good condition and appears to be lightly used. Its surfaces are clean, and it shows no significant signs of wear.

Physical and Mechanical Evaluation

Upon detailed inspection of the device’s housing, no cracks, fractures, or significant dents were detected. Its black protective frame and white main body are clean. The device’s screen is off, and no noticeable scratches or damage are observed on its surface.

All buttons, ventilation grilles, and port sockets on the device appear to be physically sound. There is no wear or fading on the buttons. There is no visible deformation in the mechanical components.

Battery and Ports

There is an internal battery unit on the bottom of the device. The label includes the phrase “PC-ASSEMBLY LUISA MV-BATTERY-M”. There is no externally visible swelling or leakage in the battery’s physical condition.

There are various connection ports on the sides of the device. These ports are:

• Sensor/accessory inputs labeled as SpO₂, CO₂, Neb (Nebulizer).
• One blue DC power input.
• A second DC power input marked as 12 V / 24 V / 48 V.
• A probable oxygen inlet with the inscription ≤ 30 l/min, < 1000 hPa.
• The main respiratory circuit connection point.
• Another connection port that could be for an alarm or data output.

Label Information

The main product label on the bottom of the device contains the following information:

• Brand: Löwenstein Medical Technology
• Model: LUISA
• REF Code: 31410
• Serial Number (SN): S20B/04/2887
• Other Code: WM 150 TD
• Manufacturer Information: Löwenstein Medical Technology GmbH, Kronsaalsweg 40, 22525 Hamburg, Germany
• Technical Information: 12 V / 24 V, 6.0 A / 3.0 A
• Protection Class: IP22
• Certification: CE0197

Additional Information

Since the device’s screen is off in the images, no information about its operating hours, menu content, or any error messages could be obtained. There is also no invoice, warranty card, or user manual visible in the images. The “S20” in the serial number suggests that the device’s manufacturing year might be 2020, but this is not certain.

Potential Risk Assessment

The current physical condition of the device is quite good. There is no visible wear, corrosion, or damage on the case, ports, or buttons. Therefore, based solely on visual inspection, the risk of an immediate failure due to the physical condition of the device appears low.

Note: This assessment is based solely on the inspection of the product’s external physical condition. It does not provide a guarantee regarding the functionality of the device’s internal electronic or mechanical components and does not mean that potential risks will definitely occur.
