The CircuFlow™ 5200 is a medical device designed for compression therapy, offering various modes of operation to suit different treatment needs. It is a compact, white unit with a digital display, a shuttle knob for navigation, and quick-connect ports for garment attachment.

Function Description:

The CircuFlow™ 5200 provides intermittent pneumatic compression (IPC) therapy, primarily for conditions requiring improved circulation or lymphatic drainage. It operates by inflating and deflating multi-chambered garments (sleeves) around the patient's limb (leg or arm) to apply pressure. The device offers three main operating modes:

Factory Default Mode: This is the pre-set mode, providing 45 mmHg pressure on the distal chamber, a 7% gradient pressure, a 30-minute treatment time, and a 30-second cycle time, with no chambers skipped. This mode is ideal for quick, standard treatments without requiring extensive setup.
Gradient Mode: This mode allows for customization of the starting pressure and the percentage drop of pressure gradient between the chambers. This is beneficial for patients who require specific pressure profiles to optimize therapy effectiveness and comfort.
Pressure Mode: In this mode, users can individually set the pressure for each of the four chambers in the sleeve. This offers the highest level of customization, allowing for precise pressure application tailored to the patient's specific anatomical needs or medical condition.

The device is designed to be user-friendly, with settings that can be modified or restored before or in between treatments. It also includes a locking feature to prevent unauthorized changes to therapy settings, ensuring patient safety and adherence to prescribed treatment protocols.

Important Technical Specifications:

Power: 120 Volts AC, 60Hz, 100 VA Max.
Fuse Rating: 1.0 Amp 250V AC (SLO-BLO).
Pressure Range (Gradient Mode): 25 – 120 mmHg (increments of 1 mmHg).
Gradient Range (Gradient Mode): 5 – 15% (increments of 1%).
Treatment Time Range: 15 – 180 minutes (increments of 15 minutes).
Cycle Time Range: 20 – 80 seconds (increments of 10 seconds).
Chambers: The device supports garments with four chambers.
Safety Features: Requires connection to a safe and properly grounded outlet.

Usage Features:

Setup:
- Unboxing: The device is shipped with protective foam covers, a power cord, an air blocker, and a user manual.
- Placement: It should be placed on a flat and stable surface near the patient.
- Power Connection: Plug the power cord into the back of the machine and into a grounded outlet.
Garment Connection: Quick connectors on the garment attach to ports on the front panel. For single-garment sessions, an air blocker must be inserted into the unused port.
Garment Application:
- Leg Garments: Unzip, place foot at the bottom, pull up, and zip while supporting the garment around the leg.
- Arm Garments: Slide the arm through the internal cavity.
Power On: Press the main POWER SWITCH up to the ON position. The green power indicator will illuminate.
Navigation and Setting Adjustment: The SHUTTLE KNOB (circular button) is used to navigate through menus, select modes, and adjust parameters (pressure, gradient, treatment time, cycle time, skip chamber). Turning the knob right increases values or moves to the next parameter, while turning left decreases values or moves to previous parameters. Pushing the knob confirms selections.
Skipping Chambers: In both Gradient and Pressure modes, specific chambers can be selected to be skipped. Note that skipping a chamber does not mean it won't fill with air, but rather with less air.
Starting Treatment: After setting parameters or selecting the Factory Default mode, press the green START button.
Prefill Stage: The pump undergoes an initial prefill stage, typically reaching 10 mmHg.
Ending Treatment: Treatment automatically ends after the set time. It can also be manually stopped by pressing the red STOP button on the front panel. If stopped manually, the treatment will not resume from where it left off.
Air Vacuum: After treatment, the device vacuums air from the garment for 1 minute to facilitate removal. For larger sleeves, an additional 1-minute vacuum cycle can be initiated by pressing STOP if all air is not removed initially.
Lock/Unlock Device:
- Locking: After setting desired treatment parameters, navigate to "Lock Device" using the SHUTTLE KNOB and confirm. A verification screen will appear; select "Yes." The device will then display "Device locked" and the password "DM."
- Unlocking: Hold down the SHUTTLE KNOB. An "Input Password" screen will appear. Use the SHUTTLE KNOB to select characters for the password "DM" and press the knob to input each character. If correct, the device will unlock and return to the menu. If incorrect, it will display "Password Incorrect" and return to the start menu.

Maintenance Features:

Post-Treatment: Once the sleeve is deflated, turn the power switch to OFF and unplug the power cord.
Garment Removal: After the power indicator light is off, the garment can be safely removed. The garment should be loose enough to unzip and remove.
Cleaning: While not explicitly detailed in the provided excerpts, typical medical device maintenance would involve cleaning the exterior of the device and the garments according to manufacturer guidelines to ensure hygiene and longevity.
Troubleshooting: The device has an "Error" indicator, suggesting built-in diagnostics for potential issues. The manual would contain specific troubleshooting steps for error conditions.
Service: The back panel of the device includes a "CAUTION: ELEC" warning, advising to refer service to qualified personnel to reduce the risk of electric shock and to ensure proper grounding.
