Löwenstein Medical Luisa Ventilator Analysis Report

Overview and Device Description

The product shown in the images is a Luisa model ventilator from the brand Löwenstein Medical. This information is confirmed both by the brand and model name on the device itself and by the accompanying instruction manual. The product is a ventilator designed for patients who require respiratory support. According to the information on the screen interface, it is understood to be suitable for use with both adult and pediatric patients. The device’s general appearance and professional interface give the impression that the product is genuine.

Quantity Information

The following items are present in the images:

• 1 Löwenstein Medical Luisa ventilator
• 1 black protective case attached to the device
• 1 Turkish instruction manual booklet

Physical State and Condition

The device appears to be in very good condition overall, despite being used. The black protective case on it indicates that the device has been protected from impacts and scratches. No significant deformation such as cracks, breaks, dents, or color fading is observed on the main casing and screen of the device. There are only minor dust and fingerprints on the screen surface and casing from use.

Electronic and Mechanical Evaluation

It is understood that the device’s electronic components are working, and its screen is on and displaying images without any issues. The light around the power button is on, confirming that the device is receiving power. No damage or functional defects are visible on the mechanical parts, such as the handle grip on the front panel and the metal connection port on the right side.

Screen Analysis and User Interface

The device’s color touchscreen is active, and its interface is in Turkish. Many of the device’s functions can be controlled via the screen. The basic information observed on the screen is as follows:

• Battery Status: In the top right corner of the screen, the battery level is shown as 81%.
• Date and Time: The date displayed on the screen is 21.12.2024, and the time is 17:31. This is the device’s current date setting.
• Active Mode: It is indicated that the device is in “PSV” mode.
• Patient Type: It is seen that there are “Adult” and “Pediatric” patient type selections in a separate menu.
• Ventilation Modes: Different ventilation modes such as PSV, VCV, P-SIMV, V-SIMV, MPVp, and MPVv can be selected from the device interface.
• System Menu: Options such as “Program settings,” “Hose system test,” “FIO2 cell” (Status: Not active), “Flight mode” (Status: Off), and “Device settings” are available.

Accessories and Documents

No accessories are present in the images other than the black protective case attached to the device. Respiratory circuit hoses, a power cable, or other connection apparatus are not included in the images. An instruction manual titled “LUISA Ventilators” and bearing the phrase “Instruction manual for patients suitable for TR LMT150TD type devices” is present with the device. Official documents such as an invoice or warranty certificate are not visible.

Label and Code Information

No label containing the device’s serial number, lot number, or REF code is clearly legible in the images. The phrase TR LMT150TD on the instruction manual may indicate the device type or a standard with which it is compliant.

Current and Potential Fault Status

Based on visual inspection, no signs of a current fault (e.g., broken parts, error codes on the screen, abnormal sounds) have been detected on the device. The device is in working order, and it is possible to navigate through the menus. The “FIO2 cell Not active” message seen on the screen is status information indicating that the relevant module is not currently in use, rather than a fault.

The good overall condition of the device and its use with a protective case suggest that significant wear and tear have been prevented. Therefore, there is no visible risk of potential failure (e.g., rust, crushed cables, severe abrasion). However, it should be noted that this assessment is a forecast based solely on visual evidence and that the full functionality of the device should be checked by a technical service.
