Problems solved by technology

The former usually causes muscle tremors due to the body temperature drop, resulting in increased energy metabolism and affecting breathing and circulation; the latter has a slow cooling rate and an unstable low temperature state, so it is not suitable for diseases that require rapid induction of mild hypothermia

Embodiment Construction

[0017] The following will refer to the attached figure 1 , 2 , 3, 4 and 5 further illustrate the technical solution of the present invention.

[0018] as attached figure 1 As shown, during treatment, the interventional catheter 1 is punctured through the femoral artery, and under the guidance of a high-definition X-ray machine, the catheter is placed in the blood vessels of the cerebral arteries, as close as possible to the location of cerebral hemorrhage or brain injury parts. The cooling liquid enters the inlet of the catheter through the liquid pushing device 5, and then reaches the head of the catheter, and fully contacts the blood in the cerebral arteries for heat exchange.

[0019] The temperature detection element 2 and the temperature detection element 2 ′ can be selected from temperature sensors, which are used to monitor the temperature of the liquid at the inlet and outlet of the conduit, and feed back the signal to the control system 3 .

[0020] The control sy...

Abstract

The invention relates to a brain fixed-point sub-hypothermia control device. The brain fixed-point sub-hypothermia control device comprises an intrusive guide tube, temperature detection elements, a control system, a liquid cooling device and a liquid pushing device, wherein the temperature detection elements (2, 2') are used for respectively monitoring the temperatures of an inlet and an outlet of the intrusive guide tube (1); the temperature detection element (2'') is used for monitoring the temperature of the output cooling liquid of the liquid cooling device (4); and the control system (3) is used for sending a control signal to start the liquid pushing device (5) to push the cooled liquid into the inlet of the intrusive guide tube at a certain speed. With the adoption of the brain fixed-point sub-hypothermia control device, the brain cooling part can be accurately positioned, the cooling process is timely and quick, and the sub-hypothermia state can be accurately and reliably maintained; in addition, acute and serious cerebral edema can be controlled, and conditions are created for promoting recovery of brain function, so that the brain fixed-point sub-hypothermia control device plays an important role in reducing fatality rate and disability rate.

Description

Technical field: [0001] The invention relates to a brain fixed-point sub-low temperature control device, in particular to a local fixed-point sub-low temperature control device for timely protection of brain function in patients with cerebral hemorrhage and severe craniocerebral injury. Background technique: [0002] Cerebral hemorrhage and severe craniocerebral injury are diseases with high mortality and disability rates. The brain tissue of patients is damaged to varying degrees. High fever and increased vascular permeability cause cerebral edema and cerebral ischemia. If not treated in time, it will promote A vicious cycle of increased pressure. [0003] Studies have shown that mild hypothermia (33-35°C) can prevent high fever caused by brain damage, reduce the oxygen consumption of brain cells after cerebral hemorrhage, improve the tolerance of brain cells to hypoxia, and reduce the risk of brain tissue damage. It can reduce the degree of brain tissue acidosis after bra...
