Intravascular heat exchange temperature regulation and control device for mild hypothermia treatment

Abstract

The invention discloses an intravascular heat exchange temperature regulation and control device for mild hypothermia treatment. The regulation and control device comprises a cooling liquid circulating conveying system, cooling liquid is normal saline, the cooling liquid circulating conveying system communicates with a detection device, a detection mechanism is used for detecting the salt content, the temperature and the water pressure of the normal saline, a built-in catheter is arranged in the body of a patient, the head and the tail of the built-in catheter communicate with the cooling liquid circulating conveying system, a controller is arranged beside the cooling liquid circulating conveying system, and the controller is connected with the cooling liquid circulating conveying system and the detection device. The regulation and control device is simple in structure and convenient to use, the detection device can be used for detecting the temperature, the salt content, the water pressure intensity and the pressure stability of the normal saline, meanwhile, deviation is avoided through mercury expansion distance measurement during temperature detection, the detection result is more accurate, and if the temperature has deviation, the temperature regulation and control mechanism is automatically started for reasonable control.

Description

technical field [0001] The invention belongs to the field of temperature control devices for mild hypothermia treatment, in particular to an intravascular heat exchange temperature control device for mild hypothermia treatment. 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. At present, mild hypothermia treatment includes body surface cooling treatment and internal cooling treatment, which are suitable for different patients. When performing internal cooling treatment, the temperature is generally measured by an electronic temperature measuring device. However, this The temperature measurement method is prone to deviation. At the same time, general treatment equipment cannot ...

Problems solved by technology

At present, mild hypothermia treatment includes body surface cooling treatment and internal cooling treatment, which are suitable for different patients. When performing internal cooling treatment, the temperature is generally measured by an electronic temperature measuring device. However, this The temperature measurement method is prone to deviation. At the same time, general treatment equipment cannot detect the stability of the pressure in the system. The stability is not high, which will directly affect the treatment effect of the treatment equipment on patients.
