PC-66B Handheld Pulse Oximeter Device Analysis Report

Device Detection and Identification

The analyzed visuals show a portable Pulse Oximeter (a device that measures blood oxygen saturation and pulse rate) used for medical measurement. The product consists of a main device unit and one finger-clip SpO2 sensor connected to it via a cable.

Brand and Model Information

The detailed visual inspection of the product revealed the following identifying information:

• Model: The clear inscription PC-66B is located on the front face of the device, in the upper left corner of the screen, and on the software interface displayed on the device’s LCD screen.
• Brand: While a manufacturer’s logo is present in the upper left corner of the device, the brand name is not written in text on the front. The model number PC-66B indicates a widely known handheld oximeter model in the industry.

Areas of Use and Function

This device is designed for use as a bedside monitor or in mobile health screenings. Its primary function is to measure blood oxygen saturation (%SpO2) and pulse rate (PR) via a sensor attached to the patient’s finger. Considering the finger clip design and the dimensions of the device in the visual, it is understood that the product is suitable for both adult and pediatric (above a certain age) use, and can be used in hospitals, clinics, or home care services.

Visual State and Physical Condition

The physical condition of the device has been evaluated based on the following criteria from the visuals:

• General Condition: The device appears to be in second-hand/used condition. However, its cosmetic condition is good, and its integrity is intact.
• Casing and Deformation: The device’s outer body has a yellow protective surface (likely rubber or silicone coating) and a black front panel. No deep scratches, breaks, cracks, or dents were detected on the casing. Slight dust accumulation is present on the black panel, particularly in the speaker grille area.
• Screen Surface: Although reflections suggest there might be very slight superficial marks on the screen glass due to use, no damage (such as broken pixels, glass cracks, etc.) affecting the screen’s readability is observed.
• Mechanical Parts: There is no visible mechanical damage on the sides or connection points of the device. The sensor clip appears mechanically sound.

Screen and Electronic Function Analysis

The following data regarding the electronic status of the device was obtained from the visual where the device is turned on:

• Operating Status: The device can power on (Power on). Screen illumination and character display are flawless.
• Screen Data: The LCD screen clearly displays the model name “PC-66B”, “%SpO2” and “PR” (Pulse Rate) parameter headings, “22:21:26” time information, and the battery level indicator.
• Warning Messages: The screen displays a “No Signal” warning. Since the sensor is not attached to a finger, this is an expected normal behavior, indicating that the sensor is detected by the device but no data is being received.

Accessories and Connections

The accessories displayed with the product and their details are as follows:

• Quantity Information: The total appears as a combined set, consisting of 1 PC-66B handheld unit and 1 wired SpO2 probe.
• SpO2 Sensor: A grey, finger-clip type probe is connected to the device. The sensor has a robust body against external impacts.
• Cable Structure: The sensor cable consists of a combination of blue and grey colors. The connector entering the device is grey and green; a secure socket structure with a locking mechanism (Push-Pull connector style) is observed. The cable has blue colored coverings near the device side and grey colored coverings on the sensor side.
• Cable Deformation: No significant breakage, crushing, or stripping (visibility of cable veins) has been detected on the cables. The cables maintain a smooth form.
• Label Information: A white barcode label is present on the cable. Parts fully readable from the visuals contain technical codes (e.g., “1AC…” or a similar serial code).

Keypad and Controls

The front panel features three main button groups:

• Navigation Keys: On the left side, keys used for up and down arrows and menu/mute functions.
• Power Key: On the right center, the red power symbol on/off button.
• Backlight/Screen Orientation: In the bottom right, the button used to change screen brightness or orientation.
• There is no noticeable fading on the symbols on the keys; the keypad appears robust.

Conclusion and Failure Risk Assessment

As a result of the examination, the PC-66B model pulse oximeter was found to be in working condition, with a sound screen, and capable of detecting sensor connection. There is no visible breakage or serious physical damage on the device that would impede its operation. The “No Signal” warning is not a malfunction but an indication that the sensor is idle. It is assessed that the product is in a suitable condition for immediate use once cleaned. As potential risks, only the possibility of battery life degradation due to long-term use or internal conductor fatigue of the sensor cable (even if not evident in the visuals) can be considered, but the current visual data indicates that the device is in good working order.
