Intravascular sub-hypothermia therapeutic apparatus for Intensive Care Unit

Abstract

The invention discloses an intravascular sub-hypothermia therapeutic apparatus for Intensive Care Unit. The apparatus comprises a mounting bracket, wherein four corners of the bottom of the mounting bracket are movably connected with universal wheels; the mounting bracket is provided with a first placement chamber and a second placement chamber; a normal saline tank is arranged in the first placement chamber and a refrigeration box is arranged in the second placement chamber; the normal saline tank is connected with the refrigeration box through a first conduit; one end, away from the first conduit, of the normal saline tank communicates to a normal saline output pipe; and a first switching valve is arranged on the normal saline output pipe. Through the arrangement of a first inner box anda second inner box in the refrigeration box of the intravascular sub-hypothermia therapeutic apparatus and through the communication between the first inner box and the second inner box by a second conduit, the normal saline in the first inner box can be fully cooled and stored in the second inner box, and the stored normal saline can be introduced into the human blood vessels and at the same time the normal saline in the first inner box can be cooled again so that an absolute cooling effect of the output normal saline can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an intravascular sub-low temperature therapeutic instrument for critical care medicine. Background technique [0002] Cardiac arrest is the sudden stop of a patient's heartbeat and breathing. Brain tissue is most sensitive to ischemia and hypoxia, and severe damage can occur 4-6 minutes after cardiac arrest. Therefore, despite active rescue to restore the heartbeat, patients often die or suffer severe neurological deficits due to severe brain damage. This is the most commonly used cooling method in our hospital. Intravascular mild hypothermia therapy involves placing a cryogenic catheter into a blood vessel, usually the femoral vein. After the catheter is connected to the sub-hypothermia treatment device, the balloon on the catheter circulates 4°C ice saline, and uses the principle of heat exchange to perform feedback cooling. Intravascular mild hypothermia has a fas...

AI Technical Summary

Problems solved by technology

Intravascular mild hypothermia has a fast cooling rate and accurate body temperature control. Although the placement of a cryogenic catheter requires blood vessel puncture, the trauma is almost negligible, and the probability of puncture-related complications is very low. The existing intravascular mild hypothermia therapy devices are loose in structure Messy, not conducive to efficient operation, and the uniform cooling effect of physiological saline in the intravascular sub-hypothermia treatment instrument cannot be guaranteed, which easily affects the treatment effect. Therefore, the present invention proposes an intravascular sub-hypothermia treatment instrument for critical care medicine
