Stöckert SIII Heart-Lung Machine Analysis Report

Overview and Device Identification

The images show a medical device system with a modular structure, mounted on a wheeled main chassis. The system consists of four pump modules, one upper control console, and one IV pole. Following examination and research, this device has been identified as a heart-lung machine (perfusion system). Irrelevant elements in the background, such as the “OTOMATİK KAPI” (AUTOMATIC DOOR) warning, have not been included in the analysis.

Brand and Model

The brand of the device is Stöckert, which is clearly visible on the modules. The model is understood to be SIII or S3, also written on the units. This model is known as the third-generation perfusion system from the Stöckert brand. The quality of the logos and lettering in the images suggests that the device is an original Stöckert product.

Areas of Use

The Stöckert SIII is a heart-lung machine. Its primary function is to temporarily take over the function of the patient’s heart and lungs during open-heart surgery. The device circulates the blood outside the body, oxygenates it, and pumps it back into the body to maintain the perfusion of vital organs. Its modular pump units manage the controlled circulation of blood and various medical fluids (e.g., cardioplegia solutions).

Quantity and Content Information

The components of the system shown in the images are listed below:

• Main Chassis: 1 unit, stainless steel, mobile (assumed to be on wheels).
• Pump Modules (Stöckert SIII): 4 units, each with its own screen and control knobs.
• Control Console: 1 unit, the larger control unit located at the top of the system.
• Pump Heads: At least 3 transparent, rotary mechanism pump heads are visible.
• IV Pole: 1 unit, integrated into the main chassis.
• Cables: Various black and blue colored cables that provide connection between modules and power to the device.

General Condition and Physical Assessment

The overall condition of the device is assessed as used. The system, which appears to be in a clinical or storage environment, is in reasonable condition for its age. No significant dirt or rust has been observed on the surfaces. However, some minor cosmetic flaws are present. There are slight scratches on the transparent plexiglass guard behind the pump units. There is tape wrapped around the metal tube of the IV pole, which has left a residue. These issues do not appear to be serious defects that would affect the device’s functionality.

Mechanical and Technical Condition

The mechanical components of the device appear largely intact upon visual inspection.

• Pump Mechanisms: The visible pump heads and rotary mechanisms are physically intact.
• Knobs and Controls: The turquoise-colored rotary knobs and other control buttons on the pump modules are in place and show no significant damage.
• Cables and Sockets: No significant crushing, cuts, or insulation damage is visible on the cables. There are various connection ports and a key mechanism at the bottom of the device, and these parts also show no obvious deformation.

It is understood from the active screens on the modules that the device is powered on and operational.

Screen and Label Analysis

The small digital screens of all pump modules and the upper control unit in the system are active. However, due to the low image quality, the text and numbers on the screens are unreadable. This indicates that, at a minimum, the modules are receiving power and their screens are working. Any labels on the device containing detailed information such as a serial number, REF code, or year of manufacture cannot be clearly read in the images. There is a green-colored label of unidentifiable nature on the upper console and on a lower pump module.

Potential Risk Assessment

Based on the visual inspection, there is no obvious evidence (broken parts, burn marks, error messages) indicating an immediate failure in the device. The overall structure and condition of the device suggest that it has been maintained. However, as with any complex and used medical device, there are potential risks that are not visible to the naked eye. Specifically, the age of the device, the lifespan of its electronic components, and the condition of its internal battery (if any) are uncertain. Minor cosmetic flaws, such as the tape residue on the IV pole, do not pose a functional risk. This assessment is a prediction based solely on visual evidence and does not guarantee the full functionality of the device. For safe use, it is recommended that the device undergo a comprehensive inspection and calibration by a professional biomedical technician.
