Abstract

The invention discloses a nasopharyngeal cavity cooling catheter for selective brain target temperature management, the nasopharyngeal cavity cooling catheter comprises a double-cavity catheter, a tail end balloon and two mutually independent branch tube channels, one end part of the double-cavity catheter is connected with the branch tube channels into a whole, the other end part of the double-cavity catheter is connected with the tail end balloon into a whole, a water inlet hole and a water outlet hole which are used for water inflow and water outflow are formed in the ends of the two independent branch pipe channels respectively, and a physical cooling instrument is arranged outside the branch pipe channels and used for controlling the flow speed and pressure of cooling water, so that the cooling water is driven to circularly flow in the sacculus at the cooling catheter end through the double-cavity catheter and does not make direct contact with peripheral tissue. By means of the mode, the product is safe and effective to patients, nerve prognosis and the survival rate can be improved, complications related to whole body cooling can be prevented, direct continuous cooling can be conducted on nasopharyngeal cavities, non-invasive brain temperature reduction can be conducted, and target temperature management of brain temperature can be conducted.

Description

technical field [0001] The invention relates to a nasopharyngeal cavity cooling tube for brain target temperature management, relates to the medical field, in particular to a nasopharyngeal cavity cooling tube for selective brain target temperature management. Background technique [0002] Acute brain injury caused by craniocerebral trauma, stroke, and cerebral ischemia secondary to cardiac arrest causes disability and death to tens of millions of people worldwide every year. Brain cooling is a promising treatment for patients with severe brain injury. The current cooling methods mostly use systemic cooling, which can cause serious systemic complications. Raphael Einsfeld Simões Ferreira of the Department of Neurology of the Federal University of Sao Paulo in Brazil proposed a new method of selectively reducing brain temperature with a novel nasopharyngeal cooling catheter. The present invention is an innovation and change based on this. Contents of the invention [0003...
