EXAMPLES

Example 1Application of Compression Therapy to an Amputated Limb

[0092] The device for compression therapy is utilized to provide compression therapy to an amputated limb of a subject in need thereof. Various compression cycles may be utilized, in accordance with various parameters, including, for example, but not limited to: the limb, characteristics of the subject (age, weight, gender, medical condition, etc.), the amputation status, amputation location, length of the stump, medical condition to be treated, and the like.

[0093] After the compression device is placed and secured to the amputated limb, the compression therapy session/cycle may be initiated.

[0094] Listed below are details of three exemplary compression therapy cycles, whereby the order of inflation/deflation of the compression cells (i.e., bladders or compression pocket (also referred to as cell no. 1)) is adjusted according to the treatment session/cycle.

[0095] The compression chambers are numbered from 1 at the bottom cell (i.e., adjustable compression pocket) to 2, 3, 4 . . . N (bladders of the compression sleeve) as progressing towards the center of the body.

Compression cycles may be sequential, peristaltic or intermittent as exemplified below:

I. Sequential Compression Cycle:

[0096] Inflate #1 [0097] Inflate #2 [0098] Inflate #3 [0099] Inflate #N [0100] [0101] Deflate all chambers

II. Peristaltic Compression Session:

[0102] Inflate #1 [0103] Inflate #2 [0104] Deflate #1 [0105] Inflate #3 [0106] Deflate #2 [0107] Inflate #4 [0108]

[0109] Peristaltic compression is facilitated by keeping/maintaining any number of chambers inflated in given time (1 chamber, 2 chambers or more).

[0110] III. Intermittent Inflation Cycle: [0111] Inflate all chambers simultaneously [0112] Deflate all chambers

[0113] Chambers may be blocked, kept not inflated during the inflation cycle (skip chambers) according to the specific medical condition being treated.
