Catheters can have a variety of materials, sizes, and shapes depending on their uses, and the uses of catheters include draining the stored contents in body cavities or various organs, aspirating perfusion fluid for cleaning, measuring cardiovascular dynamics or central venous pressure, injecting drugs or contrast agents into the body, etc.

[0003] There are disadvantages when strengthening the sealing of the traditional catheter body, and the installation of the tube body is relatively troublesome. Glass wool or hemp rope needs to be prepared in advance. In addition, the tightness or thickness of the hemp rope or glass wool will also affect the sealing effect. The gaps are likely to cause gas leakage inside the pipeline. The gas flow in the tube body cannot be measured, and its flow rate cannot be controlled. The installation and disassembly are troublesome, resulting in inconvenience in use. Therefore, a double-layer catheter for stoma is needed to improve the above problems. Utility Model Content
