[0002] Chest drainage tube is widely used to drain the gas or liquid abnormally accumulated in the chest, and chest closed drainage surgery is the most common surgery in thoracic surgery. After most thoracic surgeries, chest drainage tube is placed to drain postoperative exudate or lung gas leakage. The drainage effect is proportional to the size of the tube diameter. During the retention of chest drainage tube, the frequent contact and friction between the front end of the tube and the pleura, and the back end of the tube and the ribs, skin, etc. can cause pain and discomfort in patients, and the degree of pain is proportional to the size of the tube diameter. To alleviate the pain, severe patients actively reduce coughing or weaken respiratory movement, which adversely affects the smooth recovery of postoperative lung function and causes adverse medical experience for patients.
[0003] To reduce the pain and irritation caused by chest drainage tube, surgeons choose thinner and softer chest drainage tube to drain postoperative exudate and gas leakage while developing minimally invasive thoracic surgery. From traditional 32F silicone drainage tube to current 10F pigtail drainage tube, the contact irritation is reduced while sacrificing part of the drainage effect. Anesthesiologists use multi-mode analgesia and postoperative analgesia pump to relieve patient pain, including single-time paravertebral nerve block or paravertebral nerve catheter continuous block under ultrasound guidance, PCIA, PCEA, etc. Although the nerve block technique in the corresponding part greatly reduces the incidence of complications under the guidance of ultrasound, the effect of local anesthetic is limited in time, which limits the analgesia time. Paraneural catheter increases the risk of infection, and there is a risk of catheter falling off and breaking. Systemic drug use has side effects such as nausea and vomiting.
