Foot compression system
Methods and systems for dynamic compression of venous tissue enable improved blood movement in the extremities. In accordance with an exemplary embodiment, a pressure pad provides a compressive force to the venous plexus region of the foot. The pressure pad is successively withdrawn and re-pressed against the foot. Improved blood circulation may reduce the occurrence of undesirable complications such as deep vein thrombosis, ulcers, and the like.
1. A foot compression system, comprising:
an item of footwear comprising a flexible sole; and
an actuator portion comprising a retractable, non-bendable pressure pad, wherein the actuator portion is completely contained within the item of footwear.
2. The system of claim 1 , further comprising a reader portion that transmits commands to the actuator portion.
3. The system of claim 2 , wherein the reader portion displays information associated with the operational history of the foot compression system.
4. The system of claim 2 , wherein the reader portion further comprises a software program allowing a user to access information associated with at least one of: duration of operation of the foot compression system, number of compression cycles performed, pressure generated by the foot compression system, duration of patient ambulation, or duration of inactivity of the foot compression system.
5. The system of claim 1 , further comprising a slip clutch coupled to the retractable, non-bendable pressure pad that is configured to allow the retractable, non-bendable pressure pad to retract responsive to an applied force exceeding a predetermined value.
6. The system of claim 1 , wherein the actuator portion is configured to prevent extension of the retractable, non-bendable pressure pad responsive to an indication that the actuator portion has been moved within a predetermined time period.
7. The system of claim 1 , wherein the retractable, non-bendable pressure pad extends a distance between 1 mm and 24 mm.
8. The system of claim 1 , wherein the actuator portion extends the retractable, non-bendable pressure pad to generate an applied pressure of between 100 mmHg and 500 mmHg.
9. The system of claim 1 , wherein a portion of the retractable non-bendable pressure pad that contacts the foot has a contact surface area of between about 10 square centimeters to about 30 square centimeters.
10. The system of claim 1 , wherein the actuator portion extends the retractable, non-bendable pressure pad from a fully retracted position to a fully extended position in a time between about 100 milliseconds and about 300 milliseconds.
11. A foot compression system, comprising:
an item of footwear comprising a flexible sole;
an actuator portion comprising a retractable pressure pad, wherein the actuator portion is completely contained within the item of footwear; and
a sensor in operative communication with the actuator portion,
wherein the sensor senses when a wearer of the item of footwear is walking and operates the actuator portion in response to whether or not the wearer is walking.
12. The system of claim 11 , wherein a portion of the retractable pressure pad has a surface area of between about 10 square centimeters to about 30 square centimeters.
13. The system of claim 11 , wherein the actuator portion extends the retractable pressure pad from a fully retracted position to a fully extended position in a time between about 100 milliseconds and about 300 milliseconds.
