SonoTrax Fetal Doppler Analysis Report

Overview and Product Description

The device shown in the images is a handheld fetal doppler of the SonoTrax brand. This device is designed to listen to the fetal heart rate using ultrasound technology. The product has a white and turquoise colored plastic casing. The device features an LCD screen, a speaker grille, an on/off button, a volume control wheel, and two function buttons (Mode, Start/Stop). On its back, there is a belt clip and a battery compartment. It is understood from the label information that the manufacturer of the product is Edan Instruments Inc.

The examined images only show the device itself and its integrated probe. No other components such as a box, additional accessories, or documents are visible. Therefore, a total of 1 unit of the product is listed.

Physical Condition and Deformation

The general condition of the device has been evaluated as used. There is visible yellowing and discoloration on its white plastic casing. Dirt accumulation is present, especially in recessed areas such as around the buttons, speaker holes, and seams. No distinct cracks, breaks, or dents were observed on the device’s surface, but it generally has a worn appearance. The spiral cables attached to the device appear physically intact; there are no breaks or pinches in the cable insulation.

Technical Details and Label Information

Various technical and manufacturer details were obtained from the labels located on and within the device. Since the device’s screen was off, no digital information or menu content could be accessed.

• Product Name: Ultrasonic Pocket Doppler
• Brand: SonoTrax
• Manufacturer: Edan Instruments, Inc.
• European Representative: Shanghai International Holding Corp. GmbH (Europe)

According to the calibration label on the back of the device, information regarding its last maintenance and when the next maintenance should be performed is present. However, the fact that this date has passed raises a question mark regarding the current accuracy of the device.

• Calibration Company: TURKAY KALİBRASYON
• Certificate No.: TVT 3081
• Last Calibration Date: 12.01.2021
• Next Calibration Date: 11.2022

Although a battery cover is present on the device, the battery itself is not visible. Therefore, no comment can be made regarding the battery’s presence, type, or condition.

Potential Risk Assessment

There is no direct evidence of a malfunction, such as a broken part or an error message, on the device. However, the fact that the device’s calibration date expired in April 2022 is a significant concern for a medical device. Uncalibrated devices can yield inaccurate results in measurements. Furthermore, the device’s generally worn and yellowed appearance may indicate heavy use or prolonged storage. Apart from this, no serious physical damage that could lead to a potential malfunction in the cables or casing has been observed.
