Abstract

An anti-hemorrhage device, and an anti-hemorrhage kit, includes a rigid platform and a compression device adjustably secured to the rigid platform. The kit also includes a gastroesophageal aortic occlusion device.

Claims (25)

1. An anti-hemorrhage device comprising:

a rigid platform; and

a compression device adjustably secured to the rigid platform,

wherein the compression device comprises a pressure plate carriage and a strap carriage, the pressure plate carriage and the strap carriage being connected by a screw, the strap carriage being linearly translatable relative to the pressure plate carriage when the screw is rotated, the strap carriage being adjustably secured to the rigid platform with a first adjustable strap and a second adjustable strap, the first adjustable strap and the second adjustable strap being adjustably connected to the pressure plate carriage through an opening in the pressure plate carriage, and a pressure plate removably attached to a bottom of the pressure plate carriage.

2. The anti-hemorrhage device of claim 1 , wherein the screw comprises a first screw nested within a second screw.

3. The anti-hemorrhage device of claim 1 , wherein the pressure plate has a generally triangular shape.

4. The anti-hemorrhage device of claim 1 , wherein the rigid platform comprises a first rigid housing and a second rigid housing, the first rigid housing and the second rigid housing being connected to one another by one of a pivotable connection, a slide connection, and a snap-fit connection.

5. The anti-hemorrhage device of claim 4 , wherein each of the first rigid housing and the second rigid housing comprise a perimeter rim that surrounds a central pocket.

6. The anti-hemorrhage device of claim 4 , wherein the first adjustable strap is connected to the first rigid housing and the second adjustable strap is connected to the second rigid housing.

7. The anti-hemorrhage device of claim 1 , wherein the first adjustable strap is adjustably secured to the rigid platform proximate a perimeter of the rigid platform and the second adjustable strap is adjustably secured to the rigid platform proximate the perimeter of the rigid platform.

8. The anti-hemorrhage device of claim 1 , wherein a bottom surface of the pressure plate is one of concave-shaped or convex-shaped.

9. The anti-hemorrhage device of claim 1 , wherein a bottom surface of the pressure plate is angled with respect to the pressure plate carriage.

10. The anti-hemorrhage device of claim 1 , wherein a bottom surface of the pressure plate includes an absorbent layer.

11. An anti-hemorrhage kit comprising:

an anti-hemorrhage device including a rigid platform, and a compression device adjustably secured to the rigid platform; and

a gastroesophageal aortic occlusion device,

wherein the compression device comprises a pressure plate carriage and a strap carriage, the pressure plate carriage and the strap carriage being connected by a screw, the strap carriage being linearly translatable relative to the pressure plate carriage when the screw is rotated, the strap carriage being adjustably secured to the rigid platform with a first adjustable strap and a second adjustable strap, the first adjustable strap and the second adjustable strap being adjustably connected to the pressure plate carriage through an opening in the pressure plate carriage, and a pressure plate removably attached to a bottom of the pressure plate carriage.

12. The kit of claim 11 , further comprising a plurality of pressure plates that are adapted to be removably secured to the compression device.

13. The kit of claim 11 , wherein the rigid platform comprises a first rigid housing and a second rigid housing.

14. An anti-hemorrhage device comprising:

a rigid platform; and

a compression device adjustably secured to the rigid platform,

wherein the compression device comprises a pressure plate carriage and a strap carriage that is linearly translatable relative to the pressure plate carriage, the strap carriage being adjustably secured to the rigid platform with a first adjustable strap and a second adjustable strap, and a pressure plate removably attached to a bottom of the pressure plate carriage,

wherein the rigid platform comprises a first rigid housing and a second rigid housing, the first rigid housing and the second rigid housing being connected to one another by one of a pivotable connection, a slide connection, or a snap-fit connection, and

wherein the rigid housing comprises a plurality of interlocking teeth that align the first rigid housing and the second rigid housing when the first rigid housing and the second rigid housing are moved towards a closed position and the plurality of interlocking teeth form stabilizing buttresses with the ground when the first rigid housing and the second rigid housing are in an open and deployed position.
