Abstract

A compressive hemostatic belt which is easily operable and thrown away after use, incorporates a strip (1) in the form of a nonstretch or low-stretch textile fabric, and a bag (5) expansible by being filled with fluid that is attached to the strip at a predetermined position by an attaching device. A pump (8) and a pressure gauge (9) are connected to the bag (5) attached at the predetermined position on the strip (1), so that the bag is expanded by operating the pump so as to fill the bag (5) with a suitable fluid while watching the pressure gauge (9). The bag thus presses down on an area (A) where bleeding is to be stopped.

Claims

1. A compressive hemostatic belt system, comprising:

a mounting strip for binding a patient, said strip being formed from at least one of a non-elastic and a low-elastic material;

an inflatable bag mounted in said strip and positioned so as to compress a selected area of the body of the patient when inflated, said bag having means for inflating said bag with fluid; and

inflation directing means formed with said bag, for directing inflation of said bag, wherein the inflation of said bag is controlled so as to be directed substantially only toward the selected area of the body and prevented from inflating away from the body, wherein

said mounting strip includes a pocket holding said bag and said inflation directing means, the pocket being formed with a contact side surface positioned so as to contact with the selected area of the body of the patient and formed from an elastically expandable sheet material.

2. A compressive hemostatic belt system as claimed in claim 1, wherein said inflation directing means includes a hard case member positioned on an outer side surface of said bag so as to prevent inflation of the outer side of said bag and to induce inflation of substantially only an inner inflating side of said bag.

3. A compressive hemostatic belt system as claimed in claim 2, wherein said inflation directing means includes a doughnut-shaped flange positioned with the hard case member between said bag and a contact side surface of the pocket, a hole in the doughnut-shaped flange being positioned so as to allow inflation of said bag through the hole.

4. A compressive hemostatic belt system as claimed in claim 1, wherein said inflation directing means includes bellows formed with an inner inflating side of said bag so as to induce inflation of substantially only the inner inflating side of said bag.

5. A compressive hemostatic belt system as claimed in claim 1, wherein the contact side surface of the pocket of said mounting strip is formed with a hole defined so as to allow inflation of said bag through the hole so as to contact with the selected area of the body of the patient.

6. A compressive hemostatic belt system as claimed in claim 1, further comprising:

a fluid feed pump with a pressure gauge detachably connected to said bag through a check valve.
