a pericardial drainage tube

Abstract

The invention provides a pericardial drainage tube, which includes a tube body, a side hole, an air bag and an inflatable tube diameter; the tube body includes a head end and a tail end, the head end is in the shape of an elastic curled ring pigtail, and the tail end includes a drainage nozzle and an inflatable tube. The nozzle and the drainage nozzle are connected to the inside of the tube body; the air bag is set on the outer wall of the tube body, the side hole is opened on the tube wall of the tube body and communicated with the inside of the tube body, and the inflatable diameter is set on the tube body On the inner side of the tube wall, the inflation tube diameter communicates with the air bag and the inflation nozzle. The invention is specially aimed at the drainage problem of pericardial effusion, and the head end is in the shape of an elastic curled circular pigtail, which is beneficial to the fixation of the pericardial drainage tube in the patient's body and the drainage of the effusion. With a balloon structure, the space around the pericardial drainage tube can be extended to a certain extent to solve the problem of blockage of the drainage tube. At the same time, it can also play a fixed role. The point-like contact between the catheter balloon and the heart can reduce the stimulation of the catheter itself to the patient's heart. The onset of arrhythmia and the occurrence of pain.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a pericardial drainage tube. Background technique [0002] When the patient has pericardial effusion or pleural effusion, puncture and drainage should be performed if necessary. Pericardial or thoracic drainage with conventional needles is risky. Because the distance between the pericardium and the surface of the heart, and the distance between the pleura and the lungs is small, during the drainage process, the risk of the sharp drainage needle puncturing the heart or lungs will increase when the patient coughs, changes in body position, or has a large breathing range. Due to the limited amount of drainage each time, patients with a large amount of effusion need multiple drainages, and repeated punctures are necessary, which increases the risk of surgery and the pain of the patient. [0003] In recent years, domestic and foreign reports have successively used Seldinger puncture m...

AI Technical Summary

Problems solved by technology

Although the central venous catheter is relatively soft, it generally has a small diameter and does not have a pigtail shape at the head end. It is often ejected out of the pericardial cavity or chest cavity with the heartbeat, respiration and patient's activities; blockage occurs

Although the clinical application of the two is safer than the direct use of puncture needle drainage, they are still limited, and it is difficult to stay in the body for a long time
