<p>A medical catheter used for perfusion or discharge is composed of a perfusion tube (1) and a waste liquid educing tube (2). The outer diameter of the perfusion tube (1) is less than the inner diameter of the waste liquid educing tube (2). There is an insert hole (4) on the tube wall of the waste liquid educing tube (2) for the perfusion tube (1) passes through. One end of the perfusion tube (1) is inserted into the lumen through the insert hole (4) and slide out of the front-end of the waste liquid educing tube (2), and then into a body cavity. The head portion of the end of the perfusion tube (1) is hemispherical, or tightly covered by a hemispherical cup (7), which is made of soft material. The other end of the perfusion tube (1) is out of the waste liquid educing tube (2), and acts as a port to connect to a therapy apparatus or a liquid tank for perfusing the liquid form the outside of the body cavity into the cavity.</p> |
