Chattanooga OptiFlex 3 Knee CPM Device Analysis Report

Device Identification

The device shown in the visuals is a CPM (Continuous Passive Motion) device used in medical rehabilitation and physical therapy. The device consists of a main mechanical body, a soft pad system used to position the patient’s leg, and a hand control for operating the device.

Brand and Model

As a result of a detailed visual inspection, the brand and model of the device have been conclusively identified from the logos located on the hand control and at the side joint point.

• Brand: Chattanooga
• Model: OptiFlex 3

The model name “OptiFlex 3” is clearly legible on the upper part of the hand control, and the brand name “chattanooga” is clearly visible just below the screen.

Authenticity

The brand logo on the device’s control, the layout of the keypad, the screen interface, and the structure of the pads are entirely consistent with the manufacturer’s standard design language. The craftsmanship and industrial design of the hand control indicate that the product is an original Chattanooga production.

Areas of Use

The Chattanooga OptiFlex 3 is used in orthopedic and physical therapy fields. It is specifically utilized in the post-operative period after knee replacement surgeries (TKA), cruciate ligament operations, or joint surgeries to help the patient regain range of motion (ROM) in the knee joint and reduce edema.

Quantity Information

The visuals show a total of 1 integrated system (mechanical rail body + patient kit/pads) and 1 hand control with a wired connection to the device.

General Condition

The device is in used condition (second-hand). The overall condition of the product appears operational. The body integrity is sound. There are cosmetic signs of wear due to use, but no major damage that would impede the device’s operation is apparent.

Physical Deformations and Cosmetic Condition

Dirt and dust accumulations due to use are observed on the control surface and between the buttons. There is no significant fading of the symbols on the buttons. No deep scratches or cracks are visible on the device’s gray plastic components. No rust or bending has been detected on the mechanical metal rails.

Mechanical Components and Pads

The device has a dark navy blue/purple, vinyl-like patient kit (soft pads) attached. The pads cover the foot, calf, and thigh sections. No tears or shedding are visible on the pads, only natural creases resulting from use. The side knobs facilitating joint movement and the rail system are in place.

Electronic Components and Screen Analysis

The screen of the device’s hand control is operational. The blue backlit LCD screen appears clear and readable.

Screen Message Analysis:

• The screen displays “Current Carriage Angle 6°”. This indicates that the device’s electronic sensors are functioning and reflecting the current angle on the screen.
• A battery/power indicator-like icon or a graphical process indicator is visible in the upper right corner of the screen.

Accessories and Cabling

The device’s coiled (spiral) control cable is connected to the control and appears intact; no breaks or deformation are apparent. The main power cable of the device is present and is shown plugged into an extension cord in the visual. No carrying case, spare parts, or original box are present in the visual.

Battery Status

Since the device is shown plugged into an outlet with a cable, it receives its main power from the mains. It is not possible to determine from the external casing whether the device contains a battery for portable use.

Labels and Technical Information

Apart from the brand/model inscriptions on the control, the metallized label containing the device’s serial number, year of manufacture, or technical power values is not readable from these visual angles. Therefore, serial number and year of manufacture information could not be reported.

Usage Duration

There is no counter information on the control screen indicating the device’s total operating hours.

Current Fault and Risk Analysis

There is no indication in the visuals that the device is displaying an “Error” code; the screen shows normal operating parameters. No broken or missing parts are visible in the mechanical components. However, the accumulations between the control buttons might affect button sensitivity, therefore detailed cleaning and maintenance are recommended. As a potential risk, it is advised to check the connection points of the coiled cable for long-term use, but for now, it appears robust. The product is generally in good and working condition.
