1.1. Application

1.3. Indications

The ARTROMOT®-K3 is a motoroperated motion device used for Continuous Passive Motion (CPM) of the knee and hip joints.

The ARTROMOT®-K3 CPM device is indicated in the treatment of most injuries, postoperative states and diseases of the knee and hip joint. For example:

Suitable for use in hospitals, clinics, general practices and rental services, it is an important supplement to medical and therapeutic treatment.

- joint distorsions and contusions - arthrotomy and arthroscopy procedures in combination with synovectomy, arthrolysis or other intra articular measures

1.2. Objectives of therapy

- mobilizations of joints in narcosis - operative treatments on fractures, pseudarthrosis and inversion operations

CPM therapy with ARTROMOT®-K3 is mainly used in the avoidance of immobilization injuries, the early re-establishment of painless movement of joints and the promotion of faster healing with a positive functional result.

The ARTROMOT®-K3 should not be used with:

- the promotion of the healing of cartilage areas and damaged ligaments

- acute inflammatory processes in the joint area, if not explicitly prescribed by the doctor - spastic paralysis

- the speeding up of haematoma resorbtion - the improvement of lymph and blood circulation

- unstable osteosynthesis

- the prevention of thrombosis and embolism

Movement should not cause any pain

2. Description of the ARTROMOT®- K3 The ARTROMOT®-K3 CPM device allows extension and flexion of the knee joint in the range of –5-0-110 degrees. There is no need to convert the device when switching from the right to left side (or vice versa).

Explanation of functioning elements

Note: Fold out page 1

The ARTROMOT®-K3 features a hand-held programming unit that can be used to program and store any treatment values.

- Perform regular checks on all components for possible damage or loose connections - Damaged or worn parts should be replaced immediately with original spare parts by an authorized specialist.

- In case of patients who are adipose, particular large or very small, you should pay attention to the following:

- Before cleaning and repair disconnect the device from the main socket.

- Avoid abrasion and pressure - If necessary support the leg in a slightly abductive position

11 Socket for power adapter

- Movement must always be free of pain and irritation

14 Lower leg patient kit

- Repair and maintenance work may only be carried out by authorized persons, as otherwise all warranty services and liabilities shall be void.

3. calf length and leg rotation setting 4. patient kits

- The maximum continuous load on the leg support element is 30 kg

13 Kit straps

- Only connect the ARTROMOT®-K3 to correctly installed safety sockets.

- The ARTROMOT®-K3 may only be operated by authorized persons. - Make sure that the patient is supported in an anatomically correct way. Check the following settings/ positioning:

10 Foot plate with patient kit

12 Knob for rotation footplate

- Make sure that the characteristic values of your power supply correspond to the voltage and frequency data indicated on the ID plate.

CAUTION!

- When carrying out any work on the device, never allow liquids to get inside the housing or the hand-held programming unit. - Only use the AC-AC adapter supplied with the unit.

- The patient must be fully conscious during instruction and when using the splint.

CAUTION! The ARTROMOT®-K3 may only be operated with the attached power supply NTEV20

- The doctor or therapist must decide on a case-to-case basis wether the device can be used with the patient

15 Knee pivot point 16 Thigh patient kit

Explanation of symbols

To disconnect the device from mains, unplug the AC-AC adapter from the wall socket.

CAUTION! Before treatment begins, a test run involving several movement cycles should be carried out first without and then with the patient.

Alternating current Protective system Type B Power off

- The hand-held programming unit should be explained to the patient and must be located within the patient´s reach, so that the therapy can be interrupted if necessary.

Note: Fold out pages 1 and 17 To get a better understanding of the individual steps.

4.3. Adjusting the patient kit

4.1. Connecting the device

- Fix patient kit (14) for the lower leg and patient kit (16) for the upper leg by using the velcro tapes. (figure 6 and figure 7) - Control correct adjustment. Exercise only in painfree range of motion. Patient should be positioned with maximum comfort.

- Connect the power adapter (7) to a safety socket (120 Volt, 60 Hertz) - Turn on the device with the main switch (8)

2. You can now select the treatment values in succession by pressing the parameter keys.

5.1. Programming the ARTROMOT®-K3

3. Change the value by pressing the +/- keys.

The following treatment values can be stored by means of the hand-held programming unit. (5)

4. Continue programming (with 2 and 3) until all required values are entered.

- Knee extension

5. Press the STOP key to save all previous values.

- Knee flexion

6. Press START button: programmed values were checked automatically.

- Pause extension

7. Press START button again to start the device in therapy mode.

- Pause flexion - Force

4.2. Adjusting the femur length

CAUTION! The knee and hip axis of the ARTROMOT®-K3 should align with the patients knee and hip axis (Figure 8) After adjustments have been made, perform several test runs. When correctly adjusted, there should be no excursion of the knee and hip joint during motion.

Set the device at a knee-angle position that is not likely to cause the patient any pain. Positioning the upper leg - Open the black knurled knob (1), and move thigh support to the desired length (figure 2) Positioning the lower leg

CAUTION!

Positioning of foot dorsi- / plantar flexion

The programmed value and the actual angle measured at the patient´s knee may vary.

5.1.1. Programming the treatment values

- Loosen the two knobs (9) and adjust the foot plate at a comfortable angle. (figure 4)

The criterion for correct adjustment is that it should be possible to move the extremity without pain or irritation.

IMPORTANT: It is possible to program single or all parameters. If only some parameters were changed, the other parameters will be saved with current settings.

Positioning of foot rotation - Loosen the knurled knob (12) and move the foot plate into the required rotation position. (figure 5)

Adjusting the pauses - The pauses occur in the final position of extension or flexion and can be set separately for extension and flexion.

1. Pressing the Extension and STOP keys at the same time for one second or holding down the STOP key for five seconds enables you to change to programming mode. 7

- Possible values for pauses: 0 – 30 seconds 8

Adjusting the force (reverse on load)

Center warm-up

- Minimum setting for reverse on load: 25 kp

Warm-up allows the patient to attain gradually full programmed range of motion. The device starts in the middle between the two values set for extension and flexion. With each movement cycle the extent of movement is increased by 2 degrees until the set value is reached. The device then moves between these values.

- Maximum setting for reverse on load: 45 kp Settings are approximate! Tensile force is measured on the frame around the foot. The input setting determines the maximum resistance needed to automatically reverse the direction of motion.

Full speed & motion The full speed & motion function is only for service. The device runs at twice the maximum programmable speed to facilitate a rapid device set up.

CAUTION! The reverse circuit is purely a safety measure for cramps, spasms, locked joints, etc. The manufacturer accepts no liability if used improperly.

WARNING: Do not run the device in full speed & motion when patient is in the device!

Speed Minimum setting for speed: 1%

Run time

Maximum setting for speed: 100%

This is the individual run time for each treatment. To reset press SET key in the programming mode.
