DESIGN PHILOSOPHY

Pneumatic compression is a clinically proven modality for reducing the risks 

associated with deep vein thrombosis

1

. The Circul8 Max Vascular Therapy System 

is a self-contained, compact DVT therapy device that is tubeless, portable, 

lightweight, and battery-operated. Due to Circul8 Max’s portability, with no 

separate pumps and hoses, patients can use it at all times, ensuring maximum 

mobility during any phase of care. Additionally, Circul8 Max incorporates 

asymmetric compression for the superior emptying of veins

2

 that consists of an 

intermittent pneumatic compression device with sequential, asymmetrical, 

gradient, graduated, compression distal to proximal, duplicating the blood flow 

of an ambulating patient. Circul8 Max provides potentially life-saving mechanical 

DVT prophylaxis to patients with a continuum of DVT preventative care in the 

pre-,  intra-,  and  post-surgery  phases,  expertly  designed  to  provide 

increased compliance with breathable cuffs that enhance patient experiences

.

PURPOSE OF THIS DEVICE 

The purpose of the Circul8 Max is to aid in the prevention of DVT by helping to 

stimulate blood flow in the legs. This is accomplished by an electronically controlled 

pump delivering a set amount of air to the leg cuffs that, in turn, compress the 

calf or calves to aid blood flow out of the lower extremities. The pump will inflate 

each leg cuff to a preset pressure of 55 mmHg and deflate once the pressure is 

reached. The cycles are repeated on each device until the power is turned off. 

Internal rechargeable batteries allow the Circul8 Max to be completely portable, 

thus preventing interruptions in treatment. 

Indications for Use

The Circul8 Max Vascular Therapy System, model 08-0036, is intended to be an easy 

to use portable system prescribed by a physician for use in the home or clinical 

setting to help prevent the onset of DVT in patients by stimulating blood flow in 

the extremities (simulating muscle contractions). 

This device can be used to

:

Aid in the prevention of DVT

Enhance blood circulation

Diminish post-operative pain and swelling

Reduce wound healing time

Aid in the treatment of: stasis dermatitis, venous stasis ulcers, arterial and

diabetic leg ulcers, chronic venous insufficiency, and reduction of edema in

the lower limbs 

As prophylaxis for Deep Vein Thrombosis (DVT) by persons expecting to be

stationary for long periods of time 

CONTRAINDICATIONS 

The Circul8 Max Vascular Therapy System MUST NOT be used to treat the following 

conditions: 

Persons with suspected, active, or untreated: deep vein thrombosis,

ischemic vascular disease, severe arteriosclerosis, pulmonary edema, severe 

congestive heart failure, thrombphlebitis, or an active infection. 

On the legs where cuffs would interfere with the following conditions: vein

 

ligation, gangrene, dermatitis, open wounds, a recent skin graft, massive

edema, or extreme deformity of the leg. 

On any neuropathy.

On extremities that are insensitive to pain.

Where increased venous or lymphatic return is undesirable.

CALF CUFF APPLICATION

Wrap the cuff(s) around the calf and secure the Velcro to hold it in place. 

Make sure the wrap is snug but not too tight. When one or both wrap(s) 

are secured on the leg(s), the device(s) are ready for operation.

WHITE  power  button  for  about  a  second  until  two  BEEP 

tones are heard, and the 

p

ower light is illuminated on each 

device. To turn the device OFF, PRESS and HOLD the WHITE 

power  button  for  about  a  second.  You  will  hear  two  BEEP 

tones,  and  all  lights  on  the  device  will  no  longer  be 

illuminated.

USING THE DEVICE

The device will make a quiet “humming” sound when inflating 

and squeezing your leg. THIS IS NORMAL. The wraps will inflate 

once a minute. IF you FEEL air releasing around the legs, this is 

normal. This is a function of the device to keep your legs cool.
