Abstract

A dressing for applying compression to a wound in a patient includes a bladder having a non-deformable end wall and a deformable membrane. The dressing may include a flexible web having an adhesive layer on one side thereof for securing the dressing to the patient so as to hold the bladder against the patient'"'"'s skin. Upon inflation, the deformable membrane projects towards the patient'"'"'s skin and exerts pressure on the wound to reduce the flow of blood from the wound.

Claims

1. A dressing for applying compression to a wound in the groin of a patient, comprising:

an inflatable bladder having a non-deformable end wall and a deformable membrane connected to the end wall so as to define an enclosed space therebetween, the bladder having a deflated condition and an inflated condition; and

holding means for holding the bladder against the skin of the patient in a position substantially overlying the wound without circumscribing the leg or torso of the patient.

2. The dressing as claimed in claim 1, wherein the holding means includes a flexible web connected to the end wall of the bladder and projecting outwardly therefrom.

3. The dressing as claimed in claim 2, wherein the flexible web extends radially outward in all directions from the bladder.

4. The dressing as claimed in claim 2, further comprising a layer of adhesive on one surface of the flexible web for adhering the flexible web to the skin of the patient.

5. The dressing as claimed in claim 1, wherein the bladder in the inflated condition decreases in size in a direction away from the end wall.

6. The dressing as claimed in claim 1, wherein the end wall is transparent.

7. The dressing as claimed in claim 1, wherein the end wall and the deformable membrane are formed from the same material.

8. The dressing as claimed in claim 7, wherein the end wall and the deformable membrane are molded integrally with one another.

9. A dressing for applying compression to a wound in a patient, comprising:

a deformable membrane defining a cavity having an open end;

a non-deformable member enclosing the open end so as to define an inflatable bladder having an enclosed space bounded by the deformable membrane and the non-deformable member, the bladder having a deflated condition and an inflated condition; and

holding means for holding the bladder against the skin of the patient in a position substantially overlying the wound.

10. The dressing as claimed in claim 9, wherein the holding means includes a flexible web connected to the non-deformable member and projecting outwardly therefrom.

11. The dressing as claimed in claim 10, wherein the flexible web extends radially outward in all directions from the bladder.

12. The dressing as claimed in claim 10, further comprising a layer of adhesive on one surface of the flexible web for adhering the flexible web to the skin of the patient.

13. The dressing as claimed in claim 10, wherein the flexible web includes an aperture overlying the non-deformable member to enable the non-deformable member to be visible when the bladder is in the position substantially overlying the wound.

14. The dressing as claimed in claim 9, wherein the bladder in the inflated condition decreases in size in a direction away from the non-deformable member.

15. The dressing as claimed in claim 9, wherein the non-deformable member is transparent.

16. The dressing as claimed in claim 9, wherein the non-deformable member and the deformable membrane are formed from the same material.

17. The dressing as claimed in claim 16, wherein the non-deformable member and the deformable membrane are molded integrally with one another.
