HEMO-FORCE LITE Intermittent DVT Pump
User Manual
INTRODUCTION
The Hemo-Force is an Intermittent Pneumatic Compression System that
counteracts blood stasis and coagulation changes; two of the three major
factors that promote deep vein thrombosis (DVT) a potentially life-threatening
condition which can lead to pulmonary embolism.
The Hemo-Force is a non-invasive mechanical prophylactic system that massages
the feet or legs in a wavelike, milking motion that promotes blood flow and
deters thrombosis, helping to empty pooled or static blood from the valve
cusps of the femoral vein. Fibrinolytic activity is increased, stimulating the
release of a plasminogen activator. This therapy typically complements other
prophylactic measures, such as antiembolic stockings and anticoagulants.
Some exciting features include:
- User friendly master control unit that is designed so that its functions are self-explanatory
- Power micro switch (ON/OFF)
- An alarm light displays a fault status with an audio alarm and LED display
- LED display that can monitor errors and sleeve type of the device
- User friendly hanging bracket that provides easy attachment
INTENDED USE
The system consists of an air pump and single-patient-use compression sleeves
– one for the foot, one for the calf and one for the thigh. The air pump and
compression sleeve may be used on one lower extremity. If the air pump is used
simultaneously on both lower extremities, it is important that the identical
sleeve type be used on both legs (i.e. foot sleeve with foot sleeve, calf
sleeve with calf sleeve, or thigh sleeve with thigh sleeve). The inflation
pressure settings are pre-set by the manufacturer and cannot be changed. The
compression level for the foot sleeve is 120mmHg (16kPa). The compression
level for the calf and thigh sleeve is 40mmHg. The sleeve inflates and
maintains compression for 12 seconds. Then, the sleeve deflates for a period
of 48 seconds. As the sleeve inflates, it compresses the foot, calf or thigh
which augments venous blood flow, thereby reducing stasis. This process also
stimulates fibrinolysis; thus, reducing the risk of early clot formation.
Regularly check the system while in use, assuring pump operation and sleeve
fit.
Please note: It is NOT RECOMMENDED that patients with the following conditions
use this product without consulting with a physician.

1 – Air Tube Pair
1 – User Manual
OPERATING INSTRUCTIONS
The Hemo-Force Lite is easy to set up. The following steps should be followed.
Please read this instruction manual in its entirety before setting up.
-
Once the pump and sleeves have been removed from their packaging plug the pump into an electrical outlet. DO NOT TURN ON YET.
-
Position the pump on any flat surface or suspend the pump at the foot of the bed using the swing-out hooks. Do not hook on a slanted or curved surface.
-
Measure patient’s calf/foot/thigh circumference at the widest point to ensure proper fit.
-
Application of the Calf/Thigh sleeve(s).
a) Sleeves come in identical pairs and may be used on either leg.
b) Unfold the sleeve and lay the unfolded sleeve on a flat surface with the inside of the sleeve facing up.
c) When using dual sleeves, the identical sleeves type (same model) must be used on both legs. Sleeves combinations are calf and calf, thigh and thigh or foot and foot.
d) Position the sleeves at the appropriate ankle or knee landmark.
e) Place the patient’s leg on the sleeve lining, position the back of the knee over the popliteal opening in the case of thigh high sleeve.
f) Starting at the side opposite the air hose, wrap the main flap of the sleeve snugly around the patient’s leg.
g) Fasten the sleeve securely with the hook and loop fasteners starting at the ankle and then moving to the calf and/or thigh. Secure with tabs starting at the bottom tab marked 1, moving upwards to tab 2 then 3, etc.. Check that none of the hook and loop flaps hang off the end of the sleeve (entirety of hook and loop area is secured to the sleeve). The sleeves should fit securely but not tightly around all parts of the patient’s leg. Confirm sleeve is properly sized by checking that the index line falls between the range markers. Follow the instructions and select the next size up or down if the index line falls out of range.
h) Use the “two-finger” rule to check that the correct fit is used. Insert 2 fingers horizontally (with palm up and both fingers touching the patient’s leg) in between the sleeve and the patient. This practice should be done at both the top and bottom of the sleeves.
i) Using the same procedures apply the second identical model sleeve if needed. If only one is to be used, simply leave the unused air outlet on the pump free (no air hose attached). -
Application of the Foot sleeve(s).
a) Foot sleeves come in identical pairs and may be used on either foot.
b) When using dual sleeves the identical sleeves type (same model) must be used on both legs. Do not use in any other combination. Place the sleeve on patient’s foot ensuring the hook and loop attachments are visible.
c) Ensure a snug fit by placing two fingers around the back of the sleeve to ensure the sleeve is not too tight. Routinely inspect the patient’s feet once compression commences.
d) Using the same procedures, apply the second identical model sleeve if needed. If only one sleeve is to be used simply leave the unused air outlet on the pump free (no air hose attached). -
Air hose(s) are required to connect the sleeve(s) to the pump and are provided separately. Attach the sleeve(s) to the air hose(s) using the connectors. Each tube has a male end connector at one end and a female connector at the other. The female end will fit to the male end on the sleeve. Make certain that a click sound is heard to ensure a proper connection.
-
Attach the other end(s) of the air hose(s) (male end) to the female connector(s) on the pump. Make certain that a click is heard with each snap lock connection. If you need to disconnect tubing, firmly pull the male and female connector apart.
-
Press and hold the power button to turn pump on when air hose(s) and sleeve(s) are properly connected.
-
