Silicone ring on a fabric sock
The compression element is a silicone ring carried on a fabric sock. As the ring is rolled up the limb, it drains the blood from it. Where the ring comes to rest, it acts as the occlusion band. The sock stays on the limb as a sterile cover. A pulling cord and a transparent pulling device roll the ring, and a protective card is used at removal.
Sock trimmed to the working area
Once the ring is in position, the sock is cut at the region of the procedure. The working area then matches the operation.
Placement on the limb
On the upper extremity the ring is secured above the elbow for procedures on the lower regions. On the leg it is used for the thigh, knee and distal femur, and for the lower leg, foot and ankle.
Removal
At the end of the procedure the protective card is placed under the silicone ring, the ring is cut, and the fabric of the sock is then cut.
