## 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 a frame, which is affixed to 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.

## Claims

### Claim 1

An apparatus for improving an operating field for medical procedures for a patient comprising:
a frame with a peripheral edge and a first end and a second end;
the frame further having a centrally disposed frame opening and at least one break point area, which is oriented in between the first end and the second end;
a flexible membrane is disposed within the frame and substantially covers the frame opening;
the frame having a non-snapped frame diameter;
the flexible membrane having a centrally disposed membrane opening;
the flexible membrane and the at least one break point area form at least one channel through the apparatus and at the peripheral edge of the frame;
the first end of the frame has a first tab;
the second end of the frame has a second tab; and
the first and the second tabs outwardly extend past the peripheral edge of the frame;
whereby the apparatus can engage an appendage of the patient with said flexible membrane to provide an effective exsanguination of said appendage;
the at least one break point allows a user to snap the frame from a first unsnapped position to a second snapped position, so that the user can expand the apparatus further beyond the non-snapped frame diameter and apply or remove over any injured or repaired area of the patient's appendage; and in the second snapped position, the flexible membrane remains unbroken throughout an entire circumference of the apparatus.

### Claim 2 (depends on 1)

The apparatus of claim 1, wherein the at least one break point area further having a groove.

### Claim 3 (depends on 1)

The apparatus of claim 1, wherein the appendage is an arm, a leg or a digit.

### Claim 4

An apparatus for improving an operating field for medical procedures for a patient comprising:
a frame with a peripheral edge and a first end and a second end;
the frame further having a first centrally disposed opening and at least one breakable portion, which is oriented in between the first end and the second end;
the frame and the at least one breakable portion share a common external perimeter;
a flexible membrane is fixedly connected within the frame and substantially covers the first centrally disposed opening; and the membrane having a second centrally disposed opening;
the frame having a non-snapped frame diameter;
whereby the apparatus can engage an appendage of the patient with said flexible membrane and through the second centrally disposed opening to provide an effective exsanguination of said appendage;
the at least one breakable portion allows a user to snap the frame from a first unsnapped position to a second snapped position, so that the user can expand the apparatus further beyond the non-snapped frame diameter and apply or remove over any injured or repaired area of the patient's appendage; and in the second snapped position, the flexible membrane remains unbroken throughout an entire circumference of the apparatus.

### Claim 5 (depends on 4)

The apparatus of claim 4, wherein the at least one breakable portion further has a groove.

### Claim 6 (depends on 4)

The apparatus of claim 4, wherein the first end of the frame has a first tab; the second end of the frame has a second tab; and the first and the second tabs outwardly extend past the peripheral edge of the frame.

### Claim 7 (depends on 4)

The apparatus of claim 4, wherein the appendage is an arm, a leg or a digit.

### Claim 8 (depends on 4)

The apparatus of claim 4, wherein the flexible membrane and the at least one breakable portion form at least one channel through the apparatus and at the peripheral edge of the frame.
