Problems solved by technology

[0005] From a comprehensive analysis of the current brain protection measures for surface cooling, it can be seen that there are two key issues restricting the cooling efficiency of this type of method: on the one hand, the surface convective heat transfer coefficient is too small, resulting in insufficient cooling rate of the brain tissue; On the one hand, the cooling currently adopted is mainly limited to the body surface, and the cooling area is limited, so the rapid cooling of the brain tissue cannot be realized to the maximum extent.

Embodiment Construction

[0029] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0030]Fig. 1 is a schematic diagram of the structure and use state of the jet impact brain cooling device of the present invention. It can be seen that the jet impact brain cooling device includes: liquid refrigerant 1; driving pump 2; gas refrigerant storage tank 3; refrigerator 4; opening and closing valve 5; flow regulating valve 6; controller 7; temperature sensor; The cold cap 9 and the liftable bed; the cold cap 9 equipped with the jet impact channel 19 is a core technology of this invention which is different from the previous cold cap. The cold cap 9 includes an air cavity 93 defined by an inner cap 91 and a shell cap 92, and between the inner cap 91 and the shell cap 92; the air cavity 93 of the cold cap is provided with 1-100 jet impact channels 19 , Each jet impact channel has its own cold medium inlet and outlet; the cold medium inlet and outlet pip...

Abstract

The present invention relates to one kind of brain cooling jet impact device, which has a booster pump to pressurize the cooling medium, a cooling cap jet passage and an oral cavity pouring passage for jetting cooling medium to cool down the selected target tissue in brain quickly, an elevating bed fore required height and angle regulation, temperature sensors for taking the surface temperature and the core temperature of the patient, and a computer with treating software receiving the measured temperatures and regulating the pressure, temperature and other parameters of the cooling medium for reaching required treatment effect. The present invention has high cooling effect, automatic operation and other advantages.

Description

Technical field [0001] The invention relates to a device that can quickly cool deep tissues in the brain, and particularly relates to a device that uses a liquid jet to impact the scalp to enhance heat exchange and is supplemented by intraoral jet perfusion, thereby quickly achieving selective and rapid cooling of brain tissue The jet impingement brain cooling device. Background technique [0002] As we all know, the brain is the most important organ for maintaining life functions and conscious activities. Brain tissue consumes large amounts of oxygen, has high blood flow, and has a strong metabolism. In a resting state, the cerebral blood flow is 50-60 ml / min per hundred grams of brain tissue. Although the adult brain only accounts for about 2% of body weight, blood flow accounts for about 15% of cardiac output, and oxygen consumption is about It accounts for 20% of the body's oxygen consumption. To this end, a continuous supply of blood oxygen and energy is required, and cerebr...
