Nonin SpO2 Sensor Analysis Report

Overview and Product Description

This report contains a detailed analysis of a medical sensor, for which images are provided. The examination determined that the product is a finger-type pulse oximeter sensor (probe) used to measure blood oxygen saturation (SpO2) and pulse rate.

The Nonin brand name is clearly visible on the black-colored connector part of the product. This sensor is designed to perform non-invasive measurements by connecting to compatible bedside monitors or pulse oximeter devices. The images show a total of 1 sensor and its cable.

Physical Condition and Deformation Assessment

Although used, the product appears to be in generally good condition. No significant dirt or stains were observed on the sensor’s blue finger clip, gray cable, or black connector. A detailed examination of the outer surface revealed no critical physical deformation such as cracks, breaks, dents, or deep scratches that would impede its function. The cable integrity is preserved, with no cuts, peeling, or abrasion present.

Technical Details and Accessories

The sensor’s connector, which provides connection to the device, consists of 8 pins. The image shows that all pins are straight and clean, indicating that the electrical connection can be made without issues. No box, user manual, or additional accessories are included with the product. There is no evidence in the image that this sensor has an external or internal battery; such sensors typically draw power from the main device they are connected to. The size of the blue finger clip suggests it is suitable for use in adult patients. There are some numbers on a small white label located on the cable.

• Other Codes: 0536

Conclusion and Potential Risk Assessment

Based on the assessment of the images, there is no evidence of an existing malfunction in the device (e.g., broken parts, bent pins). The overall physical condition of the product indicates that it has been used regularly but well maintained. The robust strain relief plastic parts at the cable entries and the absence of significant wear on the cable suggest that the product may have a long lifespan. In its current condition, no immediate risk of malfunction is foreseen for the product.
