Abstract

A device for exsanguination from the hand and/or arm is described. In one embodiment, the device includes a gripping portion gripped by the hand of a patient holding the device. There is a cupped portion, and a roll of elastic wrapping material. The cupped portion has an inner space for receiving the roll and a slot for feeding out a length of wrap from the roll. The wrap material is fed out of the slot and wrapped around the hand of the patient so that the constrictive force pushes the blood out. A tourniquet is then applied and the wrap removed. In another embodiment, the device has a gripping portion with an end that is slotted to receive and anchor an end of a roll of wrapping material. With an end anchored, the material is unrolled and wrapped from the anchored end down around the hand gripping the device.

Claims

1. A method of exsanguination of an extremity comprising:

gripping with said extremity, a gripping portion of an exsanguination device;

while the extremity is gripping the gripping portion, drawing a wrapping material from storage through an exit defined in the exsanguination device; and

wrapping the wrapping material around a portion of the device and the extremity;

whereby the wrapping exsanguinates the extremity;

supporting a quantity of the wrapping material on the exsanguination device as the device is gripped by the hand being wrapped, and wherein said wrapping draws said wrapping material from said quantity through said exit; and

said wrapping is done around said hand and device whereby exsanguination of said hand occurs.

2. A method, comprising:

providing an exsanguination device having a gripping portion, a holder portion coupled to the gripping portion and having a dispensing slot, and a roll of wrapping material received by the holder portion;

gripping the gripping portion of the exsanguination device with a hand;

pulling a portion of the wrapping material out of the holder portion through the slot; and

exsanguinating blood from the hand, wherein the exsanguinating includes tightly wrapping the portion of wrapping material around the device and the hand.

3. A method, comprising:

providing an exsanguination device having a gripping portion, a dispensing portion, and a quantity of wrapping material received by the dispensing portion;

gripping the gripping portion of the exsanguination device with a hand;

dispensing the wrapping material from the dispensing portion; and

tightly wrapping the wrapping material around the device and the hand, whereby the wrapping causes exsanguination of blood from the hand.

4. The method of claim 3, wherein the dispensing portion defines an inner space and a slot in communication with the inner space, wherein the wrapping material is positioned in the inner space, and wherein the dispensing includes pulling the wrapping material through the slot.

5. The method of claim 4, wherein the dispensing portion includes an open end in communication with the inner space to enable insertion of the quantity of wrapping material into the inner space.

6. The method of claim 3, wherein the quantity of wrapping material is a roll of flexible, elastic wrapping material.

7. The method of claim 3, wherein the gripping portion includes a foam grip surrounding a core.

8. The method of claim 3, wherein the gripping portion includes a first end portion being parabaloid in shape and a second portion adjacent the first portion, the second portion being cylindrical in shape.

9. The method of claim 3, wherein the wrapping material is a stretchable, flexible, elastic wrap operable to apply a compressive force to the hand.
