ii.    Three gibbous small beams in the catheter lumen can prevent closing to make the drainage smoother.

i.      Cross-shaped support structure provides the stronger support to prevent closing, so that the sampling is convenient and reliable.

ii.    The multi-channel drainage channel is non-blocking, so that the drainage is smoother.

2.       The flexible sputum aspirator has the special anti-reflux device to prevent reflux of drainage fluid to cause wound infection when squeezing.

3.       The catheter is connected with the fluid bag to perform drainage under positive pressure, collect and measure the drainage volume largely.
