Pericardial drainage tube

Abstract

The invention provides a pericardial drainage tube, which comprises a tube body, a side hole, an air bag and an inflation pipe diameter; the tube body comprises a head end and a tail end, the head endis an elastically curled ring pigtail shape, and the tail end comprises a drainage nozzle and an inflation nozzle, the drainage nozzle communicates with the inside of the tube body; the air bag is disposed on the outer side wall of the tube body, the side hole is opened on the tube wall of the tube body and communicates with the inside of the tube body, and the inflation tube diameter is disposedinside the tube wall of the tube body, and the inflation tube diameter is communicated with the air bag and the inflation nozzle. The pericardial drainage tube is specifically for the drainage problem of pericardial effusion, and the head end is the elastically curled ring pigtail shape, which is beneficial to the fixation of the pericardial drainage tube in the patient body and the drainage of an effusion. With the airbag structure, the space around the pericardial drainage tube can solve the clogging problem of the drainage tube to a certain extent, a fixing function is provided, and the point contact between the catheter air bag and the heart can reduce the onset of arrhythmia and the onset of pain due to heart stimulation of the conduit itself to the patient.

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
