Mild hypothermia therapy-endovascular heat exchange temperature adjustment control device

Abstract

The invention discloses a mild hypothermia therapy-endovascular heat exchange temperature adjustment control device. The device comprises three parts of an endovascular catheter system, an in vitro salt water circulating system and a heat exchange controller, wherein the endovascular catheter system is connected with the in vitro salt water circulating system through a pipeline to form a closed-loop salt water flow channel; a circulating water pump controls sterile salt water to flow in the closed-loop salt water flow channel, while a heat exchange coil is soaked in refrigerant, and the temperature of the refrigerant can be changed by heating refrigeration equipment, so that the temperature of the sterile salt water is adjusted; and the heat exchange controller consists of the heating refrigeration equipment, a temperature control system and a display operation unit which are connected through a circuit. The heat exchange controller can change the temperature of the salt water in the in vitro salt water circulating system, thus temperature controlled salt water is obtained in the endovascular catheter system; and therefore, the heat is exchanged with blood of a patient through the balloon surface of the catheter system, thus the purpose of core body temperature regulation for central nervous system high-risk patients or low body temperature patients is achieved.

Description

technical field

[0001] The invention relates to the key technology in the field of medical devices, in particular to a mild hypothermia treatment-intravascular heat exchange temperature regulation and control device. Background technique

[0002] Mild hypothermia therapy refers to the controlled reduction of the patient's core temperature to protect organs from damage. As a method of brain protection, this method has been used in many brain injury diseases, and it is gradually found that it may also have a certain protective effect when other organs are damaged. Mild hypothermia treatment has been included in American Heart Association guideline for CPR and ECC and American Association of Neurological Surgeons. Guidelines for the management of severe traumatic brain jury) is listed as a recommended method. A recent questionnaire survey showed that 61% of emergency facilities in the United States use mild hypothermia. Studies have found that mild hypothermia can regulate c...
