Embodiment Construction

[0131] figure 1 Shown is a pressurized gas tank 1 made of metal or composite material containing carbon dioxide, nitrous oxide in liquid phase 2 and carbon dioxide, oxygen, nitrogen, nitrous oxide and argon in gaseous phase 3 pressurized gas. A metal or PVC connecting pipe 4 extends into the inner hollow space of the pressurized tank 1 . The pressurized tank 1 is required to be able to resist a pressure of at least 100 bar.

[0132] A gate valve 5 is operatively arranged between the delivery tube 30 and the pressurized tank 1 and is used to trigger the discharge of gas through the delivery tube 30 and the flexible wire mesh reinforcement tube 31 to the cannula 8 ( figure 1 not shown in ). The flexible tube 31 has a length of 30 cm. Check valve 6 is used for one-way filling gas, gas mixture or liquefied liquid in the tank (can also refer to Figure 5 ). In the case of overpressure inside the tank, for example caused by improper storage or excessive ambient heat, the safet...

Abstract

A device is provided for cooling intra nasally the brain of a patient, in particular of a patient suffering from cardiovascular emergency. The device comprises a pressurized gas container for containing a gas or a mixture of gases, and at least one cannula with a lumen, a proximal opening and at least one distal opening. The cannula is for introduction into the patient's nasopharynx. Upon operation, gas expands adiabatically upon exiting from the at least one cannula, thereby cools and provides a coolant effect on the nasopharynx and inside the nasal cavity.

Description

technical field [0001] The present invention relates to a method for providing internal and external cooling of a patient, in particular nasal and oral cooling to protect the patient's brain and lung cooling to protect the patient's heart muscle and other organs, according to the preambles of the independent claims Examples include methods and devices for kidney, liver and lung. Background technique [0002] Events known to result in impaired cerebral perfusion can cause permanent brain damage. Events that could have such consequences occur due to, for example, cardiac arrest, acute myocardial infarction, ischemic stroke, traumatic injury, or neurogenic fever. In the event of cardiac arrest, the most common cause of death during hospitalization after resuscitation is related to ischemic injury caused by, for example, hypoxic encephalopathy. The resuscitation of a patient in cardiac arrest who is known to have no neurological deficit is time critical. [0003] It is also k...
