Abstract

A compression belt encircles a selected portion of a patient'"'"'s body and provides temporary compression of the selected portion. The compression belt comprises an elongated belt having first and second free ends free, a tensioning cord, a handle attached to the end of the tensioning cord, closing mechanism providing a mechanical advantage, a one-way tension mechanism and a selective release mechanism. Pulling the handle causes the closing mechanism to pull the first and second free ends closer together so as to compress the selected portion of the patient'"'"'s body, the one-way tension mechanism maintains compression of the patient'"'"'s body, even in the absence of continued pulling of the handle, unless the selective release mechanism is activated, and activating the selected release mechanism releases the compression of the patient'"'"'s body.

Claims

1. A compression belt for encircling a selected portion of a patient'"'"'s body and providing temporary circumferential compression of the selected portion of the patient'"'"'s body, the compression belt comprising:

an elongated belt body having a continuous length with opposing first and second free end portions and defining a centerline extending therebetween, the belt body adapted to be wrapped circumferentially around the selected portion of the patient'"'"'s body;

a first pulley bank affixed to the first end portion, the first pulley bank including at least two pulleys arranged perpendicular to the centerline of the belt body;

a second pulley bank affixed to the second end portion, the second pulley bank including at least two pulleys arranged perpendicular to the centerline of the belt body;

a third pulley bank affixed to the belt body at a fixed distance from the second pulley bank, the third pulley bank including at least two pulleys arranged perpendicular to the centerline of the belt body;

a flexible cord interconnecting the first, second and third pulley banks, the cord having

a first cord portion extending between the pulleys of the first and second pulley banks in alternation,

a second cord portion connected to the first cord portion and extending between the pulleys of the first and third pulley banks, and

a third cord portion connected to the second cord portion and extending away from the third pulley bank;

a handle connected to the third cord portion, whereby withdrawing the third cord portion from the third pulley bank by pulling the handle away from the third pulley bank causes a shortening of the first cord portion such that the first and second pulley banks move closer together along with the first and second free end portions to which the respective pulley banks are affixed, thereby tightening the belt body around the selected portion of the patient'"'"'s body and compressing the selected portion of the patient'"'"'s body; and

a selectively releasable one-way cord lock mechanism connected to the belt body, the cord lock mechanism including

a frame defining a cord passage through which the third cord portion is routed after leaving the third pulley bank,

a locking member mounted in the frame and movable between a locked position and a released position, the third cord portion being routed against the locking member so as to bias the locking member toward the locked position, and

a release member connected to the locking member for moving the locking member between the locked position and the released position;

whereby the locking member,

when in either the locked position or the released position, allows withdrawal of the third cord portion from the third pulley bank to compress the selected portion of the patient'"'"'s body,

when in the locked position, prevents the third cord portion from retracting into the third pulley bank to maintain compression of the selected portion of the patient'"'"'s body, and

when in the released position, allows the third cord portion to retract into the third pulley bank to discontinue compression of the selected portion of the patient'"'"'s body.

2. A compression belt in accordance with claim 1, wherein the compression belt is adapted for encircling a chest area of a post-thoracic or post-cardiothoracic surgery patient.

3. A compression belt in accordance with claim 1, wherein the compression belt is adapted for encircling an abdominal area of a post-abdominal surgery patient.

4. A compression belt in accordance with claim 1, wherein the first pulley bank is permanently affixed to the first end portion.

5. A compression belt in accordance with claim 1, wherein the first pulley bank is releasably affixed to the first end portion.

6. A compression belt in accordance with claim 5, further comprising:

loop-type fastening material provided in a fastening area disposed on the first end portion; and

a quantity of hook-type fastening material connected to the first pulley bank; and

wherein the first pulley bank is releasably affixed to the first end portion by engaging the loop-type fastening material with the quantity of hook-type fastening material.

7. A compression belt in accordance with claim 6, further comprising:

a flexible anchor strap connected to the first pulley bank; and

wherein the quantity of hook-type fastening material is provided on an underside of the flexible anchor strap.
