Abstract

This invention introduces a system which allows a low level of pressure to be applied to the wound site in order to prevent bleeding during a stable period. Some models of this unit also give the option of allowing the unit to be inflated in order to increase the pressure in the area and stop bleeding if it occurs later. Automatic ways of recognizing bleeding are also introduced that utilize a computerized means of recognition and/or application of a set of proper reactions after bleeding, and an automated pressure application as well. It is believed that this unit will help human beings significantly.

Claims

1. A device for wound therapy and prevention of bleeding comprising:

a transparent pressurized balloon adapted to be placed over a body skin wound wherein intact skin is immediately contiguous such a wound;

said pressurized balloon having a lower face adapted to face such a wound and immediately contiguous intact skin;

means disposed beneath said lower face of said balloon comprising an adhesive layer adapted to span such a wound and stick to such immediately contiguous intact skin; and

means for holding said balloon in place over such a wound and immediately contiguous intact skin while said adhesive layer sticks to such immediately contiguous intact skin and said balloon applies pressure against such a wound and immediately contiguous skin without obstructing a view through said balloon, wherein said means disposed beneath said lower face of said balloon comprising an adhesive layer adapted to span such a wound and stick to such immediately contiguous intact skin comprises;

an absorbent layer disposed between said adhesive layer and said lower face of said balloon.

2. A device as set forth in claim 1 wherein said adhesive layer comprises:

openings that allow wound secretions to pass through to said absorbent layer.

3. A device as set forth in claim 1 further including:

means for setting a desired amount of inflation of said balloon.

4. A device as set forth in claim 1 wherein said means for holding said balloon in place over such a wound and immediately contiguous intact skin while said adhesive layer sticks to such immediately contiguous intact skin and said balloon applies pressure against such a wound and immediately contiguous skin without obstructing a view through said balloon comprises:

a pliable transparent strip beneath a central portion of which said balloon is disposed such that said strip has an expanse extending in opposite directions beyond said balloon to comprise regions that do not directly overlie said balloon;

said regions comprise lower faces having adhesive layers disposed thereon adapted to stick to skin;

and strippable covering material covering said adhesive layers of said regions and said adhesive layer that spans such a wound.

5. A device as set forth in claim 1 wherein said means disposed beneath said lower face of said balloon comprising an adhesive layer adapted to span such a wound and stick to such immediately contiguous intact skin comprises:

a relatively more rigid than said balloon layer disposed beneath said balloon having a lower face on which said adhesive layer is disposed.

6. A device as set forth in claim 1 wherein said means disposed beneath said lower face of said balloon comprising an adhesive layer adapted to span such a wound and stick to such immediately contiguous intact skin comprises:

a relatively more rigid than said balloon layer disposed beneath said balloon and having a lower face on which an absorbent layer is disposed, and said absorbent layer comprises a lower face on which said adhesive layer is disposed.

7. A device as set forth in claim 1 wherein said means for holding said balloon in place over such a wound and immediately contiguous intact skin while said adhesive layer sticks to such immediately contiguous intact skin and said balloon applies pressure against such a wound and immediately contiguous skin without obstructing a view through said balloon comprises:

material that has an expanse adapted to peripherally bound such intact skin including a lower face adapted to face further intact skin that is beyond, and peripherally surrounds, such immediately contiguous skin;

and an adhesive layer disposed on said lower face of said material peripherally bounding said lower face of said balloon so that when the device is in use, the sticking of said material to such further intact skin by means of said adhesive layer disposed on said lower face of said material prevents blood and wound secretion from oozing out.

8. A device as set forth in claim 7 wherein said means disposed beneath said lower face of said balloon comprising an adhesive layer adapted to span such a wound and stick to such immediately contiguous intact skin comprises:

an absorbent layer and electrode means disposed between said adhesive layer and said lower face of said balloon, and leads extending from said electrode means to provide a signal for indicating fluid absorption by said absorbent layer.

9. A device as set forth in claim 1 wherein said means for holding said balloon in place over such a wound and immediately contiguous intact skin while said adhesive layer sticks to such immediately contiguous intact skin and said balloon applies pressure against such a wound and immediately contiguous skin without obstructing a view through said balloon comprises:

a transparent member disposed in overlying relation to said balloon;

and an adjustable strap system extending from said transparent member adapted to be strapped to a living body to force said transparent member against said balloon.

10. A device as set forth in claim 9 wherein said transparent member and said balloon are shaped to be adapted to fit over a person'"'"'s groin;

and said adjustable strap system comprises an abdomen strap adapted to extend around a person'"'"'s abdomen and a thigh strap adapted to extend around a person'"'"'s thigh.

11. A device for wound therapy and prevention of bleeding comprising:

a transparent pressurized balloon adapted to be placed over a body skin wound wherein intact skin is immediately contiguous such a wound;

said pressurized transparent balloon having a lower face adapted to face such a wound and immediately contiguous intact skin;

means disposed beneath said lower face of said balloon comprising a transparent rigid plastic piece adapted to span such a wound and such immediately intact skin; and

means for holding said balloon in place over such a wound and immediately contiguous intact skin while said balloon applies pressure against such a wound and immediately contiguous skin by forcing said transparent, rigid plastic piece toward such a wound and immediately contiguous intact skin while providing a view through said balloon and said piece.

12. A device as set forth in claim 11 wherein said means disposed beneath said lower face of said balloon comprising a transparent, rigid plastic piece adapted to span such a wound and such immediately contiguous intact skin further comprises:

an absorbent layer disposed beneath said rigid plastic piece adapted to overlie such a wound and such immediately contiguous intact skin.

13. A device as set forth in claim 12 wherein said means disposed beneath said lower face of said balloon further comprises an adhesive layer disposed beneath said absorbent layer.

14. A device as set forth in claim 13 including strippable covering material that covers said adhesive layer.

15. A device as set forth in claim 14 wherein said adhesive layer comprises:

openings that allow wound secretions to pass through to said absorbent layer.

16. A device as set forth in claim 11 wherein said means for holding said balloon in place over such a wound and immediately contiguous intact skin while said balloon applies pressure against such a wound and immediately contiguous skin by forcing said transparent, rigid plastic piece toward such a wound and immediately contiguous intact skin while providing a view through said balloon and said piece comprises:

a transparent member disposed in overlying relation to said balloon;

and an adjustable strap system extending from said transparent member adapted to be strapped to a living body to force said transparent member against said balloon;

wherein said transparent member and said balloon are shaped to be adapted to fit over a person'"'"'s groin;

and said adjustable strap system comprises an abdomen strap adapted to extend around a person'"'"'s abdomen and a thigh strap adapted to extend around a person'"'"'s thigh.
