the utility model provides a prevent blocking double-deck drainage tube of cross, includes the drainage tube body, the front end of drainage tube body is equipped with the drainage section, the drainage section is including drainage outer tube and the drainage inner tube that the interval set up, is connected through the strengthening rib between drainage outer tube and the drainage inner tube, be equipped with a plurality of drainage notch along drainage tube length direction on the drainage outer tube, be equipped with a plurality of drainage hole on the drainage inner tube, the drainage outer tube is used for supporting the tissue and prevents to block, the drainage inner tube is used for forming the negative pressure and carries out the drainage.
The length of the drainage section is 25-35cm.
The length of the drainage tube body is 50-70cm.
The number of the drainage slots is 1-6.
The number of the drainage slots is four.
The reinforcing rib is a cross reinforcing rib, the inside of the drainage inner tube is divided into four negative pressure channels by the cross reinforcing rib, the drainage inner tube and the drainage outer tube are divided into four drainage channels by the cross reinforcing rib, and a plurality of drainage holes arranged on the drainage inner tube are communicated with the negative pressure channels.
The drainage holes in the two adjacent drainage channels are arranged in a staggered way.
The positions of drainage holes in the two opposite drainage channels are aligned.
The drainage holes in the two opposite drainage channels are communicated with each other in the drainage inner tube.
The number of drainage holes in each drainage channel is 10-20.
The utility model adopts the scheme and has the following advantages:
through the drainage outer tube and the drainage inner tube that design into the interval setting with the drainage section, be equipped with a plurality of drainage notch on the drainage outer tube, be equipped with a plurality of drainage hole on the drainage inner tube, during the drainage, the drainage outer tube is used for supporting tissue fragment, bloody tumor etc. prevents to block the drainage hole on the drainage inner tube, and the drainage inner tube then is used for forming the negative pressure and carries out the drainage, and the drainage is fast, efficient, and the drainage is thoroughly.
