Intravascular sub-hypothermia therapeutic instrument for intensive care unit

Abstract

The invention provides an intravascular sub-hypothermia therapeutic instrument for an intensive care unit. The intravascular sub-hypothermia therapeutic instrument for the intensive care unit comprises a device in a human body and a device outside the human body, the device in the human body comprises a central temperature sensor probe and a central pressure sensor probe which are located on the forefoot position of the paracele of the human body and a three-cavity catheter located in a blood vessel of the human body, the device outside the human body comprises a control panel which conducts coordination treatment on the whole therapeutic instrument, a normal saline tank containing normal saline and a temperature regulating tank which contains cooling liquid and conducts regulation control on the temperature of the cooling liquid, and a complete circulation system is formed among the normal saline tank, the temperature regulating tank and the three-cavity catheter. The intravascular sub-hypothermia therapeutic instrument for the intensive care unit is simple in structure and convenient to use, the defects of an existing traditional cooling method are overcome, and the safety of a patient is improved by conducting heat exchange in the blood vessel; the temperature of a brain ventricle is measured, the temperature accuracy is guaranteed, and the safety is further improved; the temperature regulating chamber is arranged, rapid cooling and slow rewarming can be achieved, and the working difficulty of medical staff is reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an intravascular sub-low temperature therapeutic instrument for intensive care medicine. Background technique [0002] The 2015 American Heart Association CPR and ECC guidelines update states: All comatose (i.e., lack of meaningful response to verbal commands) adult patients who return to spontaneous circulation after cardiac arrest should be treated with TTM (Targeted Temperature Management) , the target temperature is selected between 32°C and 36°C and maintained for at least 24 hours. Mild hypothermia treatment technology began in the 1990s. By controlling the body's central body temperature in an effective mild hypothermia state, it can achieve brain protection and improve nerve function, reduce endothelial cell dysfunction, reduce oxygen and sugar metabolism, and reduce calcium. Influx, inhibit the release of agonist-glutamate, reduce convulsions, reduce the release...

AI Technical Summary

Problems solved by technology

Traditional cooling measures, such as infusion of 4°C saline, ice cubes, alcohol scrub bath, water circulation cooling blanket, application of hibernation mixture, etc., have a high incidence of chills, muscle tremors, arrhythmia, blood pressure drop, and coagulation disorders in patients , and the effect of reducing the central temperature is poor, the existing sub-hypothermia treatment equipment is cumbersome to operate, and the work intensity of medical staff is high
