JACE Universal K 100 Knee CPM Device Analysis Report

Device Identification, Brand and Model Information

The medical device in the examined images is a Continuous Passive Motion (CPM) device used in orthopedics and physical therapy to help patients regain joint range of motion (ROM). The device is mounted on a seemingly wheeled and height-adjustable, subsequently added transport stand (table).

As a result of detailed visual analysis, the device’s identification information has been determined as follows:

• Brand: JACE
• Model: Universal CPM – K 100 (The phrases “JACE Universal” and “CPM – K 1” are visible on the main body, and “Type: JACE K 100” is readable on the label on the motor housing).
• Product Type: Lower extremity (knee and hip) rehabilitation robot.
• Origin: Based on the American flag and “MADE IN USA” inscription on the label, its origin has been confirmed as the United States of America.

Cosmetic and Physical Condition Analysis

Upon examining the device’s external casing and structural components, the following cosmetic details have been observed:

• Case Color and Condition: The main plastic body of the device is cream/white. There is general yellowing and localized dirt on the plastic surfaces due to time and use. However, no cracks or major fractures are observed on the casing.
• Metal Parts: The metal frame supporting the leg is greenish-gray. Although there are local abrasions and scratches on the paint, the integrity of the metal has been preserved. No severe signs of rust (deep corrosion) were observed in the image, only superficial dirt is present.
• Patient Contact Surfaces: The foot and leg immobilization apparatus (boot/cover) is gray and equipped with black Velcro straps. The fabric/foam part appears to have maintained its shape, but it may require cleaning or replacement for hygienic reasons.
• Transparent Protective Cover: The transparent polycarbonate cover located over the motor and electronic unit is in place. It is noted that there are dust accumulations around the motor block beneath the cover. No significant cracks are visible on the cover itself.

Mechanical and Electronic Components Assessment

The following determinations have been made regarding the functional parts of the device based on the images:

• Control Unit: The device’s original JACE brand wired hand control is present. The keypad and LCD screen area on the control unit appear physically intact. The inscriptions on the buttons (GO/STOP, SPEED, FORCE etc.) are readable. No significant deformation or disconnection is visible at the input socket of the control cable.
• Motor and Movement System: The motor mechanism moving on the device’s main rail system is present in the image. The visible parts of the worm screw or rail system maintain their integrity.
• Carrier Unit (Stand): The device is positioned on a non-original, but suitably sized table/stand. The stand’s wheels and metal leg appear sturdy. It is understood that the stand is not an original part of the device but an external piece of furniture providing ease of use.

Control and Interface Analysis

The hand control, seen in detail in the 4th image, is the main center where the device’s functions are controlled. The functions on the panel are as follows:

• Screen: Sections are available where “TIME”, “EXT” (Extension), “ANGLE”, “FLEX” (Flexion) information is displayed.
• Control Buttons: “UP/DN” arrow keys, “SPEED”, “FORCE”, “GO/STOP”, “PAUSE” buttons are present.
• Adjustment Switches: At the bottom, there are manual “SET” and “RUN” sliding switches. These switches are plastic and appear sturdy.

Label Data and Technical Warnings

The yellow-backed labels and other technical information located under the transparent cover include the following:

• Warning Signs: A “Caution – Risk of Electric Shock” warning and a lightning bolt symbol within a yellow triangle are present to indicate the risk of electric shock.
• Certifications: The “CE” mark, indicating the product’s compliance with European standards, is present.
• Production Information: The American flag logo and manufacturing location information are on the label.
• Reference Codes: The device model code “Type: JACE K 100” is readable.

Areas of Use and Purposes

This device is used after orthopedic surgery (especially after operations such as total knee replacement, cruciate ligament repair, fracture fixation) to prevent joint stiffness, reduce edema, and increase range of motion. It is suitable for use in physical therapy clinics and orthopedic departments of hospitals. Not only the knee, but also the hip joint can be rehabilitated with appropriate attachments (although the setup in the image focuses on the knee).

Current Status and Risk of Malfunction Assessment

General Condition: The device is a second-hand, used product. Cosmetically, it shows its age (color changes, accumulated dust) but its structural integrity is complete.

Missing Parts Check: The main unit, leg support sections, hand control, and electrical connection cables are present in the image. However, the fabric pads that come into contact with the patient (present in the image but of uncertain hygienic condition) may need to be replaced before use.

Potential Risk of Malfunction:

• Dust accumulation under the device’s motor cover indicates that maintenance may not have been performed for a long time. The mechanical rails may need to be cleaned and lubricated.
• Age-related embrittlement may occur in plastic parts (especially at the hand control cable connection points and casing joints); this could lead to a risk of cracking from physical impacts.
• Age-related issues such as dead pixels or fading in the liquid crystal structure of the screen (not visible as it is off in the image) should not be overlooked.
• However, during visual inspection, no breaks, disconnected cables, or severe impact marks that would prevent the device from operating are observed. Its condition can be described as “in working condition, requiring maintenance”.

Quantity Information

In the images, there is 1 main device unit (along with its transport stand) and 1 hand control connected to this device.
