Penlon AV 600S Ventilator Device Analysis Report

Overview and Product Description

The device shown in the images consists of one Penlon AV 600S model ventilator and a battery pack that has been subsequently mounted on it. The front panel of the device also features an InterMed logo. This product is a medical device typically used to provide respiratory support to patients during anesthesia. The controls on the front panel allow for the adjustment of parameters such as tidal volume, minute volume, and respiratory rate.

• Brand: Penlon
• Model: AV 600S
• Product Type: Ventilator Device
• Quantity: 1 ventilator unit, 1 external battery pack

Physical Condition and Deformation Analysis

The device is in a generally used condition. Minor scratches, stains, and scuff marks are observed on its white metal casing. On the top surface of the casing, there are two empty screw holes, suggesting that another apparatus may have been previously mounted. The front and rear panels of the device have a cleaner appearance compared to its casing. The analog pressure gauge and control knobs on the front panel are physically intact and solid. The edges of the “Short Form Operating Instructions” label on the side of the device are slightly peeling.

Electronic Components and Battery Status

The most notable aspect regarding the current state of the device’s electronic components is the external battery pack, which has been subsequently and amateurishly mounted onto the unit. This battery is secured to the casing using various tapes, and its cable connections are exposed and messy. This situation suggests that the device’s original internal battery may be faulty, leading to this modification. The front panel features indicators and a switch for power status, such as “POWER,” “ON/RUN,” and “STANDBY/OFF,” but since the device is not operational, the functionality of these parts cannot be determined from the images. The two digital displays are also off.

Accessories and Connection Ports

The respiratory hoses, power cable, or other standard accessories required for the device’s operation are not present in the images. The only visible “accessory” is the external battery pack that has been added to the device. The rear panel of the device has several connection ports:

• AC power input socket
• DRIVING GAS input
• EXHAUST outlet
• PRV 80 cm H₂O pressure relief valve port
• A connector for REMOTE / MANUAL PRESSURE TRANSDUCER
• An adjustment screw for TIDAL VOLUME ADJUSTMENT/CALIBRATE

Label Information and Technical Details

Various technical information and codes can be read from the labels on the device. The main label on the rear panel contains manufacturer information and some technical specifications.

• Brand: Penlon
• Manufacturer: Penlon Limited, Abingdon, Oxon, OX14 3PH, UK
• Model (Type): AV600S
• REF Code: A small label on the rear panel shows the text “REF AVD99S 01”.
• Serial Number: Although there is a “Serial No” heading on the labels, the number in this field is not legible in the images.
• CE Mark: CE0120
• Country of Manufacture: Made in UK
• Operating Pressure: 2.8-6.9 BAR / 280-690 kPa
• Other Information: The instruction label on the side panel contains the part number “Part No. 500-001004 Issue 1”.

Fault Detection and Potential Risk Assessment

The most obvious problem in the images is the external battery attached to the device with tapes and its exposed cables. This is strong evidence that there is a fault in the device’s original power supply and that it has undergone unprofessional intervention. This modification in itself constitutes an existing fault condition.

Potential Fault Risk: The greatest potential risk with the device stems from the aforementioned external battery modification. The exposed and disorderly cables pose a risk of short circuits, electric shock, and sudden interruptions in the device’s operation. This situation seriously jeopardizes the electrical safety and operational reliability of the device. This assessment is a prediction based solely on visual inspection and indicates that using the device before it is inspected and repaired by a professional technical service would be risky. Apart from this, although there is age-related wear on the device’s general casing, no serious mechanical fractures or damage have been observed.
