Multifunctional balloon dilatation catheter for in-vivo lung membrane oxygenation

Abstract

The invention discloses a multifunctional balloon dilatation catheter for in-vivo lung membrane oxygenation comprising a catheter seat located at the near end of the catheter, an expansion balloon located at the far end of the catheter and M channels located in the catheter. The M channels at least comprise a balloon expansion channel, a positioning detection channel, a supply channel and a secretion discharge channel; The catheter seat is a multi-channel connecting device, and the M channels are respectively connected to a treatment device outside the catheter through the catheter seat; The catheter is inserted into a pulmonary bronchiole. The balloon expansion channel is used for expanding the narrow part of the airway; The positioning detection channel is used for positioning in the insertion process; The supply channel is used for continuously supplying oxygen or medicine to a patient; The secretion exclusion channel is used for excluding secretions in the airways. When the catheter is used for emergency treatment of pneumonia patients, particularly COVID-19, measures such as airway expansion, oxygen supply, sputum suction and biopsy can be synchronously carried out at the same time, so that the survival rate of the patient is increased, and lung damage is reduced.

Description

[0001] priority statement [0002] This application claims the priority of the U.S. patent application No. US62977325 (Intracorporeal Membrane Oxygenation Balloon Catheter System for Rapid Treatment of Novel Corona virus Disease (COVID-19)) submitted on February 16, 2020. technical field [0003] The invention relates to the field of membrane lung oxygenation, in particular to a multifunctional balloon dilatation catheter and method for in vivo lung membrane oxygenation. Background technique [0004] Since December 2019, the novel coronavirus pneumonia (COVID) epidemic has broken out in various countries around the world, and it has become a major medical problem that needs to be solved urgently all over the world. The COVID-19 (novel Coronavirus Disease 2019) coronavirus is the cause of the epidemic of novel coronavirus pneumonia. After the virus enters the human body mainly through respiratory and digestive tracts, it binds to the angiotensin-converting enzyme 2 receptor (...

Problems solved by technology

At present, although bronchoscopy and conventional sputum suction techniques can be used to clean and expel sputum, they are limited to high-level airways, and their functions are single. They are basically ineffective for lung inflammation storms in patients with new crowns. , alveolar lavage, continuous oxygen supply, nebulization and drug administration" in one multi-functional device is used for the first aid of new crown patients
