Non-Pneumatic Tourniquet Device

Abstract

This invention presents a non-pneumatic tourniquet device designed for quick, easy application to an injured digit, such as a finger or a toe. One preferred embodiment comprises an inner frame that is surrounded by a flexible layer or membrane and allows for an opening for the insertion of the injured digit through the device. This easy to use apparatus temporarily checks the bleeding or blood flow by applying an external pressure or a compression to the blood vessels in an appendage and also allows for exsanguination of the injured area.

1 . An apparatus for improving an operating field for medical procedures comprising, a frame and a flexible membrane;
 the frame has a frame surface, a peripheral edge, a first end, a second end, and a centrally disposed opening; the frame surface having at least one aperture along the peripheral edge of the frame;   the first end of the frame having a first tab; the second end of the frame having a second tab; the first and the second tabs outwardly extend past the peripheral edge of the frame;   the frame having at least one groove, which is oriented in between the first and the second end;   the flexible membrane having a first membrane portion and a second membrane portion;   the first membrane portion covers the frame, except for the first and the second tabs;   the second membrane portion forms a web with a centrally disposed membrane opening;   and the web is able to slidably engage an appendage of a patient.   
     
     
         2 . The apparatus of  claim 1  wherein the first and the second tabs have at least one boss; the flexible membrane having at least one hole located approximately near the at least one frame groove. 
     
     
         3 . An apparatus for improving an operating field for medical procedures comprising, a frame with a peripheral edge and a first end and a second end;
 the frame further having a centrally disposed opening;   the frame having a frame surface;   the frame surface having at least one aperture, which is oriented along the peripheral edge of the frame and passes completely through the frame;   the first end of the frame having a first tab;   the second end of the frame having a second tab;   the first and the second tabs outwardly extend past the peripheral edge of the frame;   the frame having at least one groove, which is oriented in between the first and the second end;   a flexible membrane covers the frame and substantially covers the frame opening and passes through the at least one aperture through the frame; and the membrane having a centrally disposed membrane opening, which is able to slidably engage an appendage of a patient.   
     
     
         4 . The apparatus of  claim 3  wherein the first and the second tabs have at least one boss. 
     
     
         5 . An apparatus for improving an operating field for medical procedures comprising, a frame with a peripheral edge and a first end and a second end;
 the frame further having a centrally disposed opening;   the frame having a frame surface;   the frame surface having at least one aperture, which is oriented along the peripheral edge of the frame;   the frame having at least one break point, which is oriented in between the first and the second end;   a flexible membrane covers the frame and substantially covers the frame opening and passes through the at least one aperture through the frame;   and the membrane having a centrally disposed membrane opening.   
     
     
         6 . The apparatus of  claim 5  wherein the first end of the frame has a first tab;
 the second end of the frame has a second tab;   the first and the second tabs have at least one boss; and   the first and the second tabs outwardly extend past the peripheral edge of the frame.   
     
     
         7 . The apparatus of  claim 6  wherein the frame has at least one light emitting diode, which is connected to a battery. 
     
     
         8 . The apparatus of  claim 6  wherein the frame has at least one bladder for holding antiseptic material. 
     
     
         9 . The apparatus of  claim 6  wherein the frame surface has at least one frame boss. 
     
     
         10 . The apparatus of  claim 6  wherein the flexible membrane has at least one integral support rib.
