Löwenstein Luisa Ventilator Device Analysis Report

Device Description and Intended Use

The product shown in the visuals is a Löwenstein brand Luisa model ventilator device. This device is designed for pediatric and adult patients requiring respiratory support. The device, which appears suitable for both hospital and home use, can provide invasive and non-invasive ventilation. Its portable design allows it to be used in mobile applications such as wheelchairs or stretchers. A black carrying bag bearing the brand’s logo is also included with the device.

Brand and Model Identification

Upon detailed examination, the Löwenstein brand and Luisa model name are clearly visible on the device’s front panel. On the device’s rear label, the brand is stated as “Löwenstein Medical Technology,” while the model name “LUISA” and model code LM150TD have been confirmed. Additionally, the Löwenstein logo is present on the black carrying bag included in the set. Based on this information, the brand and model of the product have been definitively identified.

Quantity and Contents

The products in the visuals are listed below:

• 1 unit Löwenstein Luisa (LM150TD) ventilator device
• 1 unit Löwenstein brand original carrying bag

General Condition and Status Assessment

The general condition of the device is quite good. Based on visual inspections, it is believed that the product has been used very little or not at all. No significant physical deformities such as prominent scratches, dents, cracks, or discoloration have been observed on the casing. The device’s surface is clean and has a well-maintained appearance. There is also no damage on the screen surface.

Technical Details and Hardware Analysis

Mechanical and Electronic Components: The device’s casing, buttons, ventilation grilles, and port inputs are visually in perfect condition. The upper section features control buttons for battery status, settings, USB, and alarm functions. Various connection ports are located on the side panels. These include power input (12 V / 24 V / 48 V), oxygen (O₂) input, patient circuit outputs, and connection points designed for sensor modules such as SpO₂, CO₂, and Neb (Nebulizer). All these components appear robust and undamaged.

Accessories: The only accessory included with the device is the carrying bag bearing the brand’s own logo. The condition of the bag is also nearly new. No power cable, adapter, patient circuit, or any other accessory is visible in the visuals.

Battery Status: A circular cover is visible on the device’s rear panel, indicating an internal or easily replaceable battery system. However, since the battery itself is not visible, no comments can be made regarding its physical condition (swelling, leakage, etc.). There are no battery-related deformities on the casing.

Current and Potential Status

Current Fault: There is no evidence in the visuals to suggest that the device is faulty (broken part, error message on screen, warning light). Since the device is in a powered-off state, no functional test comments can be made, but it is physically entirely sound.

Potential Fault Risk: Given the product’s nearly new physical condition, cleanliness, and absence of any signs of wear, no immediate fault risk is anticipated. The device visually presents a problem-free and reliable impression.
