## Abstract

The present invention provides an improved bilateral compression device for post-operative surgical site, the bilateral compression device including a central cavity presented by an outerwall and a circumscribing sidewall, the central cavity in receipt of a post-operative pillow further comprising an outer membrane separated from an inner membrane for exerting a central compressive force towards the post-operative surgical area which varies from a surrounding compression force.

## Claims

### Claim 1

A post-operative bilateral compression device comprising:
a central cavity presented by an outerwall and a circumscribing sidewall, said circumscribing sidewall presenting a contoured surface;
a band secured to said circumscribing sidewall for securing said post-operative bilateral compression device during use; and
a post-operative pillow received by said central cavity and further comprising an outer membrane separated by an inner membrane and adapted for exerting a central compressive force and a surrounding compressive force towards a post-operative surgical site.

### Claim 2 (depends on 1)

The post-operative bilateral compression device of claim 1 said inner membrane further comprising a left side and a right side wherein at least some of one of said left and right side is removable.

### Claim 3 (depends on 1)

The post-operative bilateral compression device of claim 1 wherein said inner membrane presents a smooth, non-stick surface.

### Claim 4 (depends on 1)

The post-operative bilateral compression device of claim 1 wherein said inner membrane has a coating.

### Claim 5 (depends on 1)

The post-operative bilateral compression device of claim 1 wherein said post-operative pillow provides reduced central compressive force.

### Claim 6 (depends on 1)

The post-operative bilateral compression device of claim 1 wherein said circumscribing sidewall presents a sealing surface which extends along the post-operative surgical site.

### Claim 7 (depends on 1)

The post-operative bilateral compression device of claim 1 further comprising a compression membrane positioned between said inner and outer membrane.

### Claim 8 (depends on 1)

The post-operative bilateral compression device of claim 1 wherein said outer membrane provides visibility through said post-operative bilateral compression device.

### Claim 9 (depends on 1)

The post-operative bilateral compression device of claim 1 wherein said band further comprises a plurality of indicia which allow for quantitative adjustment of said central compressive force.

### Claim 10 (depends on 1)

The post-operative bilateral compression device of claim 1 further comprising a plurality of pressure sensors embedded in said post operative pillow for quantitative adjustment of said central compressive force.

### Claim 11 (depends on 1)

The post-operative bilateral compression device of claim 1 wherein said band includes a receiver for receipt of a compression measurement tool for quantitative adjustment of said central compressive force.
