Abstract

A hydrostatic pressure application device for stopping bleeding from an internal wound has a balloon captured within the confines of a net. The net is secured to the area surrounding the wound by sutures tied in surgical thread so that when hydraulic pressure is applied by connecting flexible tubing to the balloon causing it to expand, the capturing of the balloon within the net will cause pressure to be applied to the surface of the wound, thus stopping any bleeding. The device and the surgical threads are removable through an incision when the bleeding from the internal wound has stopped.

Claims

1. A device for applying hydrostatic pressure to an internal wound comprising:

an expansible balloon constructed and arranged to hold fluid;

means to restrain the movement of said expansible balloon; and

means to conduct fluid to said expansible balloon;

whereby when said expansible balloon is restrained from movement with respect to the wound, fluid may be conducted into said expansible balloon so as to expand said expansible balloon within said means to restrain the movement of said expansible balloon thus applying pressure to the internal wound.

2. The device as defined in claim 1 wherein said means to restrain the movement of said expansible balloon includes a net.

3. The device as defined in claim 2 further including sutures for attaching said net to the area surrounding the wound.

4. A hydrostatic pressure application system for an internal wound comprising:

a source of fluid for applying varying hydraulic pressure;

a balloon constructed and arranged to hold fluid;

means to restrain the movement of said balloon, said means to restrain the movement of said balloon surrounding said balloon; and

means to conduct fluid from said source of fluid to said balloon;

whereby when said balloon is restrained from movement away from the internal wound, fluid may be conducted into said balloon from said source of fluid at varying hydraulic pressure so as to expand said balloon and apply pressure to the internal wound.

5. The system as defined in claim 4 wherein said balloon, said means to restrain the movement of said balloon and said means to conduct fluid are constructed and arranged to pass through an incision in their unexpanded state.

6. A hydrostatic pressure application system for an internal wound comprising:

a source of fluid for applying varying hydraulic pressure;

a balloon constructed and arranged to hold said fluid;

a net surrounding said balloon;

a flexible tube for conducting fluid from said source of fluid to said balloon;

surgical thread for attaching said net to the area surrounding the internal wound;

whereby when said balloon is restrained from movement away from the internal wound by said surgical thread, fluid may be conducted into said balloon from said source of fluid at varying hydraulic pressures so as to expand said balloon and apply pressure to the internal wound, but when said balloon is in its unexpanded state, said attachment of said net by said surgical thread may be released, and said balloon, said net and said flexible tube may be removed from the internal site of the wound through an incision in the body.

7. The system as defined in claim 6 wherein that portion of said surgical thread which passes through said incision is shielded by a catheter tube.

8. A method for stopping bleeding from an internal wound comprising the steps of:

attaching an expansible flexible container to a source of hydraulic pressure;

inserting said expansible flexible container into a bag made from an open weave fabric;

securing said bag to the area surrounding the internal wound; and

applying hydraulic pressure to the expansible flexible container.

9. The method as defined in claim 8 wherein said bag is secured to the area surrounding the internal wound by sutures of surgical thread.

10. The method as defined in claim 9 wherein said surgical thread is conducted through catheter tubes.
