Product Description
The BluFlex DVT Prophylaxis System is a non-invasive intermittent pneumatic
compression system that aids in prevention and reduction in incidence of deep vein
thrombosis (DVT), a potentially life threatening condition, which can lead to pulmonary
embolism.
The system consists of a pump and soft pliable compression single patient use
garments for leg or foot compression. The pump supplies compression on a pre-set
inflation pressure of 40mmHg for calf and thigh compression, and 80mmHg for foot
compression. Pressure in the garments is transferred to the extremities, augmenting
venous blood flow, thus reducing stasis. This process also stimulates fibrinolysis; further
reducing the risk of early clot formation.
Please note: It is NOT RECOMMENDED that patients with following symptoms use this
product without consulting a physician.
Caution
Contraindications for use:
The use of the BluFlex DVT Prophylaxis System is NOT RECOMMENDED in the
following conditions –
1. Severe congestive cardiac failure.
2. Severe arteriosclerosis or other ischaemic vascular disease.
3. Extreme deformity of the limbs.
4. Known or suspected deep vein thrombosis.
5. Known or suspected Pulmonary Embolism.
6. Any local condition in which the garments would interfere: i.e.
i. Gangrene
ii. Dermatitis
iii. Untreated or infected wounds
iv. Recent skin grafts

Operating Instructions
To operate the BluFlex DVT Prophylaxis System the following steps should be followed:
Please read this instruction manual in its entirety before setting up.
1. Plug pump into an appropriate electrical outlet. DO NOT SWITCH ON.
2. Position the pump on flat surface or suspend the pump at the foot of the bed using the swing-
out hooks.
3. Place garment(s) on the legs or feet, ensure the male Velcro does not touch the patient’s
skin. Use only foot or only calf/thigh for dual garment therapy; don’t mix foot with calf/thigh
garment.
4. Snugly wrap garment, making sure the inflatable bladder is in the correct orientation.
Garments are labelled to indicate correct positioning. When correctly positioned, secure with
the tabs. Garments should fit securely but not tightly around the patient’s extremity. Repeat
the procedure for the other limb. If only one garment is used, disconnect one of the hoses
from the pump.
5. Air tubing is required to connect garment(s) to the pump. Attach the garments to the air
tubing using the white snap lock connectors. Each tube has a male end connector at one end
and a female end connector at the other. The female end (large white connector) will fit to the
male end (small white connector) that is on the garment. Make certain that a “click” sound is
heard to ensure a solid connection.
6. Attach the other end(s) of the air tubing (male end) to the large white female connector(s) on
the pump. Make certain that a click is heard with each snap lock connection. If you need to
disconnect the tubing, press the silver tab on large white (female) connector and pull apart.
7. Press the on/off switch to turn pump on.
8. Pump will start initialization process for approximately 10 seconds.
9. Pump will automatically detect Single/Dual garment/s during initialization process. The pump
is set to default to Dual Calf/Thigh garments.
10. To switch to Foot Therapy, while pump is in operation press “FOOT” button for approximately
3 seconds until “FT” is displayed. To switch back to Calf/Thigh Therapy while the pump is in
operation, press “CALF/THIGH GARMENTS” for approximately 3seconds until “LEG” is
displayed.
11. If the pump is in operation on Dual Garments Therapy and you want to change to Single
Garment Therapy, disconnect one of the hoses from the pump and press “SINGLE GARMENT.”
The pump will start initialization process for 10 seconds and the Single Garment Therapy will
begin.
12. If the pump is in operation on Single Garment Therapy and you want to change to Dual
Garment Therapy, attach the second hose and garment and press “SINGLE GARMENT.” The
pump will directly start the Dual Garment Therapy.

13. TIMER –To activate the TIMER, switch the pump and timing will commence. The TIMER
reflects HOURS of compression. If compression is interrupted i.e. the patient is removed from
therapy, and the pump is switched off at the power switch; the timer will suspend timing until
the patient is reconnected to therapy and therapy is continued.
14. RESETTING TIMER –to reset the timer press “RESET TIMER” for 5 seconds and it will reset.
Always reset timer prior to new therapy to ensure correct time is measured.
15. Disconnect Device：Switch the device off, disconnect from power supply and remove
garments from the patient.
Note:
Ensure that there are no kinks in the tubing and the connectors are properly locked. Never
apply or remove the garments while inflated as this may damage to the garments.
