Background technique

At present, after breast cancer surgery, local subcutaneous fluid will appear. The current conventional treatment methods include local puncture and fluid extraction, local pressure bandage or drainage with negative pressure drainage device. The treatment method of local puncture and aspiration requires multiple puncture and dressings, which increases the pain of the patient and is easy to cause infection. In addition, the puncture and aspiration cannot maintain continuous drainage, and the effect is not good; while the pressurized bandage increases the pain of the sick. Discomfort.

The method of drainage with negative pressure drainage device overcomes the shortcomings of the above two treatment methods, and is currently used more. Existing negative pressure drainage devices generally include a drainage tube and a drainage container. One end of the drainage tube is connected to and communicated with the drainage container, and a puncture needle is provided at the other end. When in use, when the puncture needle punctures the skin, and one end of the drainage tube is left in the patient's skin, the subcutaneous fluid is introduced into the drainage tube by the puncture needle, and then introduced into the drainage container through the drainage tube. Although this structure overcomes the problem that local puncture and pumping fluid cannot be continuously drained, the drainage tube of this structure also has the following disadvantages: breast cancer surgery will cause a large area of trauma in the chest cavity and armpit, and even breast-conserving surgery will still be difficult. It will cause a large area of trauma in the armpit alone, and the existing negative pressure drainage device, because there is only one drainage tube under the skin, not only cannot realize the rapid drainage of the pleural cavity and subarmpit effusion at the same time, but also the drainage effect is not ideal.
