Emergency brain cooling device and method of use
The present invention is directed to a scarf having a sealable pocket. Within the pocket is a Joule-Thompson gas chamber having an activation device. When the activation device is triggered, the compressed gas is released from the Joule-Thompson gas chamber through at least one restriction aperture into the sealable pocket. That release results in at least the walls of the sealed pocket being cooled. Prior to being cooled or after being cooled, the scarf is placed over a portion of the patient's body. Preferably, the scarf is positioned over at least one of the patient's carotid arteries, preferably both, to effectively cool the patient's brain and/or body core temperature.
1 . A flexible cooling apparatus comprising
a flexible material having sufficient length to at least contact a desired portion of a patient's body;
a chamber within the flexible material;
a Joule-Thompson container having a pressurized gas and being attached to the flexible material;
a throttling valve that directs the pressurized gas from the Joule-Thompson container into the chamber;
an activating device positioned over the flexible material and controls the operation of the throttling valve;
wherein when the activating device is triggered to operate the flexible cooling apparatus, the pressurized gas is released from the Joule-Thompson container into the chamber where the gas reduces the temperature in the chamber.
2 . The apparatus of claim 1 wherein the Joule-Thompson container is within the chamber.
3 . The apparatus of claim 1 wherein the flexible cooling apparatus is positioned over at least one carotid artery of a patient.
4 . The apparatus of claim 1 wherein the flexible cooling apparatus is positioned over both carotid arteries of a patient.
5 . The apparatus of claim 1 further comprising a flap that separates the chamber from the exterior environment.
6 . The apparatus of claim 5 wherein the flap is resealable and allows a user to insert or remove items from the chamber.
7 . The apparatus of claim 5 wherein the flap permanently seals the chamber from the exterior environment.
8 . The apparatus of claim 2 wherein a heat sink surrounds the Joule-Thompson.
9 . The apparatus of claim 1 wherein the Joule-Thompson container is re-fillable with gas.
10 . The apparatus of claim 1 wherein the Joule-Thompson container is disposable.
11 . The apparatus of claim 1 wherein the flexible cooling apparatus is disposable.
12 . The apparatus of claim 1 further comprising a cooling pad in the chamber.
13 . The apparatus of claim 1 further comprising a cooling fluid in the chamber.
14 . The apparatus of claim 1 further comprising a cooling fluid and a cooling pad in the chamber.
15 . The apparatus of claim 1 wherein the wherein the flexible cooling apparatus is a self-contained device.
16 . The apparatus of claim 1 wherein the gas is selected from the group consisting of CO 2 , N 2 O, nitrogen, argon, or a mix of argon and nitrogen.
17 . A method of using a flexible cooling apparatus comprising
triggering an activating device interconnected to a throttling valve that directs a pressurized gas from a Joule-Thompson container, that is attached to a flexible material having sufficient length to at least contact a desired portion of a patient's body, to a chamber within the flexible material where the gas reduces the temperature in the chamber;
applying the flexible cooling apparatus to a patient's body to cool the patient.
18 . The method of claim 17 wherein the Joule-Thompson container is within the chamber.
19 . The method of claim 17 wherein the flexible cooling apparatus is positioned over at least one carotid artery of a patient.
20 . The method of claim 17 wherein the flexible cooling apparatus is positioned over both carotid arteries of a patient.
21 . The method of claim 17 further comprising a flap that separates the chamber from the exterior environment.
22 . The method of claim 21 wherein the flap is resealable and allows a user to insert or remove items from the chamber.
23 . The method of claim 21 wherein the flap permanently seals the chamber from the exterior environment.
24 . The method of claim 18 wherein a heat sink surrounds the Joule-Thompson.
25 . The method of claim 17 wherein the Joule-Thompson container is re-fillable with gas.
26 . The method of claim 17 wherein the Joule-Thompson container is disposable.
27 . The method of claim 17 wherein the flexible cooling apparatus is disposable.
28 . The method of claim 17 further comprising a cooling pad in the chamber.
29 . The method of claim 17 further comprising a cooling fluid in the chamber.
30 . The method of claim 17 further comprising a cooling fluid and a cooling pad in the chamber.
31 . The method of claim 17 wherein the wherein the flexible cooling apparatus is a self-contained device.
32 . The method of claim 17 wherein the gas is selected from the group consisting of CO 2 , N 2 O, nitrogen, argon, or a mix of argon and nitrogen.
33 . A flexible cooling apparatus comprising
a flexible material having sufficient length to at least contact a desired portion of a patient's body;
a Joule-Thompson container having a pressurized gas and being positioned over the flexible material;
a throttling valve that directs the pressurized gas from the Joule-Thompson container into the chamber;
an activating device positioned over the flexible material and controls the operation of the throttling valve;
wherein when the activating device is triggered to operate the flexible cooling apparatus, the pressurized gas is released from the Joule-Thompson container into the environment where the gas reduces the temperature in the container.
