Intravascular mild hypothermia therapeutic apparatus for intensive care unit

Abstract

The invention discloses an intravascular mild hypothermia therapeutic apparatus for the intensive care unit. The intravascular mild hypothermia therapeutic apparatus comprises a storage box, an air conditioner and a venous tube; an air inlet penetrates through one side of the upper surface of the storage box, one end of a first air tube is fixedly connected into the air inlet, and the other end ofthe first air tube is fixedly installed in an air outlet of the air conditioner; two air outlets penetrate through the other side of the upper surface of the storage box, one end of a second air tubeand one end of a third air tube are fixedly installed in the two air outlets respectively, the other end of the third air tube is fixedly connected with an air inlet of the venous tube, and one end of the fourth air tube is fixedly connected in the air outlet of the venous tube. The human body temperature can be kept between 32 DEG C and 36 DEG C within 24 hours, cold air can be continuously generated, the cold air can be directly exhausted after absorbing heat, and compared with a normal saline cooling mode, the structure is simpler, and the working efficiency is improved.

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 cooling measures of the sub-hypothermia therapy instrument include infusion of 4°C saline, ice cubes, alcohol scrub bath, water circulation cooling blanket, application of hibernation mixture, etc. Because the patient has high fever, it will have a certain impact on various organs and tissues, especially the nervous system damage. , Hyperthermia can cause irreversible damage to brain cells due to protein denaturation and enzyme dysfunction. A large number of experimental studies have shown that the sub-hypothermia treatment of patients can make the patient's body temperature in a controllable low temperature state, so that the central nervous system is in a state of inhibition, and the response to external and various pathological stimuli is weakened,...

AI Technical Summary

Problems solved by technology

[0003] Among them, compared with the body surface cooling method, the intravascular sub-low temperature cooling speed is fast, the cooling process is easy to control, and the target temperature is stable. The existing intravascular sub-low temperature cooling method is to pass normal saline through the heat exchange bulb at the end of the central venous catheter The capsule is placed in the blood vessel of the human body, so that the normal saline can exchange heat with the blood in the heat exchange balloon, and the temperature can be continuously circulated to cool down. Although this method can cool down the blood vessel at a sub-low temperature, it needs to cool down the constantly circulating normal saline control, resulting in complicated instruments and reduced work efficiency
