Definitions
- the present disclosure generally relates to the field of vascular therapy for application to a limb of a body, and more particularly, to a compression apparatus having removable portions.
- a major concern for immobile patients and persons alike are medical conditions that form clots in the blood, such as, deep vein thrombosis (DVT) and peripheral edema.
- DVT deep vein thrombosis
- Such patients and persons include those undergoing surgery, anesthesia, extended periods of bed rest, etc.
- These blood clotting conditions generally occur in the deep veins of the lower extremities and/or pelvis.
- These veins such as the iliac, femoral, popiteal and tibial return deoxygenated to the heart.
- a static pool of blood is ideal for clot formations.
- a major risk associated with this condition is interference with cardiovascular circulation. Most seriously, a fragment of the blood clot can break loose and migrate.
- a pulmonary emboli can form blocking a main pulmonary artery, which may be life threatening.
- the conditions and resulting risks associated with patient immobility may be controlled or alleviated by applying intermittent pressure to a patient's limb, such as, for example, a leg, to assist in blood circulation.
- a patient's limb such as, for example, a leg
- Known devices have been employed to assist in blood circulation, such as, one piece pads and compression boots. See, for example, U.S. Patent Nos. 6,290,662 and 6,494,852 .
- sequential compression devices consist of an air pump connected to a disposable wraparound pad by a series of air tubes.
- the wraparound pad is placed around the patient's leg. Air is then forced into different parts of the wraparound pad in sequence, creating pressure around the calves and improving venous return.
- a compression apparatus according to the preamble of claim 1 is known from US-A-4 624 248 .
- prophylaxis sequential compression apparatus that reduces bulk and is not cumbersome during use to improve comfort and compliance to a patient. It would be desirable if the prophylaxis sequential compression apparatus includes a removable portion to achieve the advantages of the present disclosure. It would be highly desirable if the prophylaxis sequential compression apparatus has a valve connector that facilitates quick disconnect from a pressurized fluid source. It is contemplated that the prophylaxis sequential compression apparatus is easily and efficiently manufactured.
- the invention provides a compression apparatus according to claim 1.
- a compression apparatus that reduces bulk and is not cumbersome during use to improve comfort and compliance to a patient for overcoming the disadvantages and drawbacks of the prior art.

- the thigh bladder air supply line will remove easily along with the thigh bladder, attaching at or near the point where the thigh bladder is removed from the sleeve. This would allow for a single motion to accomplish both removing of the thigh bladder and the thigh bladder supply line.
- the convertible sleeve allows the patient to use a more comfortable sleeve (knee vs. thigh) as risk for DVT decreases after surgery. This provides practitioners with various options while using a single apparatus.
- the compression apparatus is perforated for improved compliance and comfort with the patient during the overall length of time for wearing the apparatus. It is contemplated that the apparatus can be used with both nomadic and/or stationary compression systems.
- a pressurized fluid source continues to deliver pressurized fluid after removal of the valve.
- the pressurized fluid source can signal a high alarm if there are kinks in the tubing and a low alarm if there are leaks in the tubing.
- the compression apparatus is sequentially activated by increasing pressure through the tubes to correspond with the three portions of the sleeve.
- the distal end is the ankle bladder (high pressure)
- the proximal end is the thigh bladder (low pressure).
- the pressurized fluid source pumps air to the sleeve in a 60 second cycle with 11 seconds being compression and the rest being decompression.

Abstract
Description
- The present disclosure generally relates to the field of vascular therapy for application to a limb of a body, and more particularly, to a compression apparatus having removable portions.
- A major concern for immobile patients and persons alike are medical conditions that form clots in the blood, such as, deep vein thrombosis (DVT) and peripheral edema. Such patients and persons include those undergoing surgery, anesthesia, extended periods of bed rest, etc. These blood clotting conditions generally occur in the deep veins of the lower extremities and/or pelvis. These veins, such as the iliac, femoral, popiteal and tibial return deoxygenated to the heart. For example, when blood circulation in these veins is retarded due to illness, injury or inactivity, there is a tendency for blood to accumulate or pool. A static pool of blood is ideal for clot formations. A major risk associated with this condition is interference with cardiovascular circulation. Most seriously, a fragment of the blood clot can break loose and migrate. A pulmonary emboli can form blocking a main pulmonary artery, which may be life threatening.
- The conditions and resulting risks associated with patient immobility may be controlled or alleviated by applying intermittent pressure to a patient's limb, such as, for example, a leg, to assist in blood circulation. Known devices have been employed to assist in blood circulation, such as, one piece pads and compression boots. See, for example,
U.S. Patent Nos. 6,290,662 and6,494,852 . - For example, sequential compression devices have been used, which consist of an air pump connected to a disposable wraparound pad by a series of air tubes. The wraparound pad is placed around the patient's leg. Air is then forced into different parts of the wraparound pad in sequence, creating pressure around the calves and improving venous return.
- A compression apparatus according to the preamble of claim 1 is known from
US-A-4 624 248 . - These known devices may suffer from various drawbacks due to their bulk and cumbersome nature of use. These drawbacks reduce comfort, compliance and may disadvantageously prevent mobility of the patient as recovery progresses after surgery.
- Therefore, it would be desirable to overcome the disadvantages and drawbacks of the prior art with a prophylaxis sequential compression apparatus that reduces bulk and is not cumbersome during use to improve comfort and compliance to a patient. It would be desirable if the prophylaxis sequential compression apparatus includes a removable portion to achieve the advantages of the present disclosure. It would be highly desirable if the prophylaxis sequential compression apparatus has a valve connector that facilitates quick disconnect from a pressurized fluid source. It is contemplated that the prophylaxis sequential compression apparatus is easily and efficiently manufactured.
- The invention provides a compression apparatus according to claim 1.
- Accordingly, a compression apparatus is provided that reduces bulk and is not cumbersome during use to improve comfort and compliance to a patient for overcoming the disadvantages and drawbacks of the prior art. The compression apparatus includes a removable portion to achieve the advantages of the present disclosure. Most desirably, the compression apparatus has a valve connector that facilitates quick disconnect from a pressurized fluid source. The compression apparatus is easily and efficiently fabricated.
- The compression apparatus, in accordance with the principles of the present disclosure, includes a thigh length compression sleeve that converts to a knee length sleeve via tearing away and removing the thigh bladder and disconnecting the thigh bladder air supply line. In one embodiment, the thigh bladder air supply line will remove easily along with the thigh bladder, attaching at or near the point where the thigh bladder is removed from the sleeve. This would allow for a single motion to accomplish both removing of the thigh bladder and the thigh bladder supply line. The convertible sleeve allows the patient to use a more comfortable sleeve (knee vs. thigh) as risk for DVT decreases after surgery. This provides practitioners with various options while using a single apparatus.
- The compression apparatus is perforated for improved compliance and comfort with the patient during the overall length of time for wearing the apparatus. It is contemplated that the apparatus can be used with both nomadic and/or stationary compression systems. A pressurized fluid source continues to deliver pressurized fluid after removal of the valve. The pressurized fluid source can signal a high alarm if there are kinks in the tubing and a low alarm if there are leaks in the tubing. The compression apparatus is sequentially activated by increasing pressure through the tubes to correspond with the three portions of the sleeve. The distal end is the ankle bladder (high pressure), the proximal end is the thigh bladder (low pressure). The pressurized fluid source pumps air to the sleeve in a 60 second cycle with 11 seconds being compression and the rest being decompression.
- In one embodiment, in accordance with the principles of the present disclosure, the compression apparatus includes a sleeve configured for disposal about a limb. The sleeve includes a first portion defining a first expandable chamber and a second portion defining a second expandable chamber and a third expandable chamber. The second portion includes a connector in fluid communication with a pressurized fluid source and the first expandable chamber, the second expandable chamber and the third expandable chamber thereby facilitating fluid communication between the pressurized fluid source and the chambers. The first portion is removable from the second portion.
- According to the invention, the first portion is connected to the second portion via a perforated attachment. The first portion may be configured for disposal about a first part of the limb and the second portion is configured for disposal about a second part of the limb. The second expandable chamber may be disposed with the second portion for disposal about a second part of the limb and the third expandable chamber is disposed with the second portion for disposal about a third part of the limb.
- The compression apparatus can include a variety of welds and bladders forming a quilting effect. For example, the first, second and third expandable chambers can each define at least one sub-chamber.
- The sleeve may define at least one ventilation opening. The at least one opening can include openings formed in a surface of the expandable chambers. The at least one opening may include a slit disposed between the second expandable chamber and the third expandable chamber.
- The connector can communicate with the chambers via a tubular pathway. The tubular pathway of the first expandable chamber may be removable from the connector. A pressurized fluid may be delivered to the chambers for expansion thereof in a sequential time interval such that, for example, the first expandable chamber is expanded, followed by (2.5 seconds later) the second expandable chamber, followed by (3 seconds later) the third expandable chamber to a total of 11 seconds from the start of the first expandable chamber. The chambers are then all simultaneously vented to the atmosphere.
- In an embodiment, the compression apparatus includes a sleeve configured to wrap about a leg and defining a plurality of ventilation openings. The sleeve includes a thigh portion defining a first inflatable chamber having sub-chambers. The sleeve further includes a calf portion defining a second inflatable chamber having sub-chambers and an ankle portion defining a third inflatable chamber having sub-chambers. The ankle portion includes a valve connector that fluidly communicates both a pressurized fluid source and the chambers via a tubular pathway to facilitate inflation of the chambers. The thigh portion is removably connected to the calf portion via a perforated attachment and the tubular pathway of the first inflatable chamber is removable from the valve connector.
- In an embodiment, the compression apparatus includes an expandable sleeve that is configured for disposal about a leg. The sleeve extends a length from below a knee of the leg to above the knee. The sleeve is convertible from the length extending from below the knee to above the knee, to a length extending solely below the knee. The length of the sleeve extending from below the knee to above the knee may include a first portion disposed about a thigh of the leg, the first portion being removable from the sleeve. The first portion is connected to the sleeve via perforations.
- In one disclosed method, the ankle bladder is compressed for 2½ seconds, the mid-section bladder is compressed for 2½ seconds and the proximal section bladder is also compressed for 2 ½ seconds. After the 11th second elapses, all bladders are vented simultaneously. The thigh portion may be tom away, thereby converting from a full leg to a knee length. A ventilation slit is disposed on the back of the calf portion. This dissipates heat, relieves itching and accommodates movement. A knit or hosiery under the compressive sleeve may be used.
- A disclosed method of performing compression on a limb of a body includes the steps of providing a sleeve configured for disposal about the limb, the sleeve includes a first portion defining a first inflatable chamber and a second portion defining a second inflatable chamber and a third inflatable chamber, the second portion includes a connector in fluid communication with a pressurized fluid source and the chambers thereby facilitating fluid communication between the pressurized fluid source and the chambers, the first portion is removable from the second portion; disposing the sleeve about the limb; delivering pressurized fluid to the first inflatable chamber; delivering pressurized fluid to the second inflatable chamber; delivering pressurized fluid to the third inflatable chamber; deflating the chambers; and removing the first portion from the second portion.
