WEINMANN VENTIlogic LS Respiratory Device Analysis Report

Device Identification

The main product shown in the images is a portable mechanical ventilator device that provides advanced respiratory support. Alongside the device are a carrying case, power cable, air filter, and various respiratory circuit accessories.

Brand and Model

Detailed analysis reveals that the device’s brand is clearly visible as WEINMANN on the front and rear prints. The model name, VENTIlogic LS, is explicitly stated on the front panel below the screen and on the rear label. The label on the front of the device includes the text “New! Now including: SIMV, aVCV, Vt>50mL”, confirming that it is a version with advanced modes (SIMV, aVCV).

Authenticity

Considering the print quality of the logos on the device, the typography of the “Made in Germany” labels on the rear, and the material craftsmanship, the product is assessed to be an original WEINMANN production.

Areas of Use

The WEINMANN VENTIlogic LS is a life support respiratory device. It is used in both invasive (tracheostomy, etc.) and non-invasive (via mask) ventilation therapies. It is suitable for use in hospital or home settings for the treatment of adult and pediatric patients with home care needs, COPD, neuromuscular diseases, or respiratory failure. It features a 15mm – 22mm standard hose connection.

Quantity Information

The following parts have been identified in the images:

• 1 WEINMANN VENTIlogic LS ventilator main unit.
• 1 device carrying bag (black, compartmentalized).
• 1 clear nasal cannula (appears used).
• 1 packaged air filter set.
• 1 packaged spare part/accessory (small packet).
• 1 power cable (visible inside the bag).

General Condition

The device cosmetically shows signs of heavy use. The outer casing is fully present but is in a tired condition. Particularly, the discoloration of the plastic components indicates that the device has been used for a long time or has been stored on a shelf. The device is not new; it falls into the “used” category.

Physical Deformation

On the front of the device, particularly in the white/beige plastic area around the handle, there is significant yellowing (discoloration). This condition typically occurs due to ABS plastic being exposed to UV light or aging. On the rear metal panel (black part), there are shiny spots and slight abrasions. No missing feet or mounting elements such as screws are observed on the device.

Mechanical Components

The black carrying handle on the top of the device appears intact. The black menu control wheel (dial) on the front panel is in place. No physical breakage has been detected in the air outlet port.

Electronic Components

In the images, the device is in the off position, therefore, no visual data regarding its electronic functions, screen brightness, or operational performance is available. No deep cracks are visible on the screen surface, but there are fingerprints/dirt marks that need cleaning.

Accessories

The original carrying bag is present with the device, and its protective foam inserts are in place. Among the accessories inside the bag:

• Air Filter: In sealed packaging, unused condition.
• Small Spare Part: In a sealed bag labeled “WEINMANN”, unused condition.
• Nasal Cannula: The exposed tubing and cannula set are discolored (yellowed) and dull. This part appears to be a hygienic risk and to have reached the end of its life; it absolutely must be replaced with a new one.

Battery Status

VENTIlogic LS models are portable devices with internal batteries. In the images, the battery compartment is closed, and no physical swelling or damage is visible, but considering the device’s manufacturing year (2010), if the batteries have not been replaced recently, there is a very high probability that they have lost their charge retention capacity.

Label Information

The data obtained from the rear label is as follows:

• Manufacturer: Weinmann GmbH + Co. KG (Hamburg – Germany)
• Model Reference: TYP: VENTIlogic LS
• Voltage Values: 115 V ~ / 230 V ~, 50-60 Hz (Suitable for international use).
• Current Values: 0.8 A / 0.4 A.
• Warning Labels: A German safety warning starting with “Vor Offnen des Gerates…” (Before opening the device…), indicating that the plug must be disconnected before opening the device, is present.

Screen Analysis

Since the device is turned off, it could not be determined whether the screen is functioning or if there are any pixel defects. No physical crack is visible on the screen.

Year of Manufacture

The inscription “2010” is clearly visible directly below the barcode on the device’s rear label. This indicates that the device belongs to the 2010 manufacturing year.

Potential Malfunction Risk

Since the device was manufactured in 2010, it is 15 years old. The external cosmetic wear (yellowing) in the images confirms that the device has been used for a long time or has been exposed to heat/light. It is possible for electronic components and sensors to lose their sensitivity over time. Furthermore, the old appearance of the hose set in the image indicates that it poses an infection risk and must be replaced before use. Although the stains on the back of the device require superficial cleaning, whether there has been liquid contact inside the device should be determined by a technical service inspection.
