Definitions

  • Sequential compression wraps are commonly used for therapeutic and other medical and medical-related purposes.
  • sequential compression wraps are used to help treat deep vein thrombosis (DVT), joint and muscle issues with knees, hips, shoulders and other body parts, and swelling in the arms and legs due to circulatory and other problems (for example, due to lymphedema).
  • DVD deep vein thrombosis
  • DVT affects up to two million people in the United States each year. DVT typically occurs when a blood clot (thrombus) forms in one or more deep veins of the body, such as the femoral vein or the popliteal vein, or veins in the pelvis. DVT can occur without symptoms, but in many cases it causes pain, swelling, redness and superficial vein engorgement. DVT can be a serious condition. For example, a blood clot due to DVT can dislodge, travel through the blood stream and lodge in a lung, thereby blocking blood flow and resulting in a pulmonary embolism.
  • a blood clot due to DVT can dislodge, travel through the blood stream and lodge in a lung, thereby blocking blood flow and resulting in a pulmonary embolism.
  • intermittent pneumatic compression can help patients with DVT, joint and muscle issues and conditions such as lymphedema.
  • intermittent pneumatic compression can be provided to a body part by a compression wrap that is attached to an air pump and wrapped around the body part.
  • the air pump is controlled using a microcontroller and solenoids to systematically cause the compression wrap to inflate and deflate thereby providing intermittent compression to the body part.
  • the compression wrap can be wrapped around a thigh, a foot, a calf, or a thigh and calf together in order to compress the main arterial vein to promote blood flow and prevent coagulation of the blood which may lead to clotting.
  • a sequential compression wrap includes separate chambers and bladders within the wrap that compress at different times.
  • the bladders within the wrap can be sequentially inflated starting with the bladder most distal to the heart and continuing toward the bladder that is the most proximal to the heart thereby creating a "milking" action of the body part(s) on which the compression wrap is placed.
  • the bladders within the wrap can be sequentially inflated starting with the bladder most distal to the heart and continuing toward the bladder that is the most proximal to the heart thereby creating a "milking" action of the body part(s) on which the compression wrap is placed.
  • blood flow in the leg is stimulated and blood is pushed through the leg toward the heart.
  • sequential compression wraps There are different types of sequential compression wraps.
  • One type of sequential compression wrap includes separate bladders that are not fluidly connected together. For example, a separate air tube runs from an air pump to each bladder in the compression wrap.
  • a typical air pump for this type of wrap includes an internal air pump, multiple solenoids and a microcontroller. The microcontroller is programmed to cause the solenoids to operate in a manner to control the flow of air to each chamber and sequentially hold and release pressure in each chamber as desired.
  • Another type of compression wrap includes fluidly interconnected bladders separated by weld baffles.
  • This type of compression wrap has only one air inlet for receiving air from the pump, which is typically located in the bladder of the wrap that will be most distal to the heart when the wrap is placed on the body.
  • the fluidly interconnected bladders and weld baffles are configured such that the air will fill the distal bladder first until a certain pressure is achieved, at which point the air will be forced around a first weld baffle and then begin filling the second bladder. Once a certain pressure is reached in the second bladder, the air is forced around a second weld baffle and begins filling the third bladder. Once the third bladder has been inflated, the pump shuts off allowing the bladders to deflate. Once the bladders have deflated, the process is repeated. In this manner, sequential inflation of the wrap and sequential compression of the body part to which the wrap is connected are achieved.
