Abstract

The invention relates to the technical field of fluid control, in particular to a flow guide adjusting device. The device comprises a guide tube and an adjusting assembly, the guide tube comprises a pipe wall, a channel limited by the pipe wall and a side hole formed in the pipe wall, one end of the channel is an inlet, the other end of the channel is an outlet, and the side hole is communicated with the channel and located between the inlet and the outlet. The adjusting assembly comprises an air source, a balloon and an air pipe, the balloon is arranged in the channel and located between the outlet and the side hole, and the air source is connected with the balloon through the air pipe and used for inflating or deflating the balloon. The balloon expands after inflation to at least partially block the channel and increase the amount of fluid discharged through the side hole, and the balloon contracts after deflation to reduce blocking of the channel and increase the amount of fluid discharged through the outlet. The flow direction and flow of fluid in the guide tube can be adjusted by changing the state of the balloon.

Description

technical field [0001] The present disclosure relates to the technical field of fluid control, in particular to a flow guide adjustment device. Background technique [0002] Extracorporeal membrane oxygenation (ECMO) is a percutaneously implantable mechanical circulation assistance technology. The extracorporeal cardiopulmonary support auxiliary device usually consists of three parts: the host, the pump head and the membrane oxygenator. The host computer controls and monitors the operation of the extracorporeal cardiopulmonary support device, the pump head is used to circulate blood inside and outside the body, and the membrane oxygenator is used to provide oxygen and exchange carbon dioxide in the blood discharged from the body. The extracorporeal cardiopulmonary support device mainly drains venous blood from the patient's body to the outside of the body, and reinfuses the blood after being oxygenated by a membrane oxygenator and removing carbon dioxide in the blood to the...
