Description

Technical Field

[0001] The utility model relates to the field of pericardial drainage tubes, and more specifically, to a pericardial drainage tube. Background Art

[0002] A pericardial drainage tube is a tube used to drain fluid or blood in the pericardial cavity. This kind of drainage tube is mainly used to treat diseases such as pericardial effusion and pericardial hematocele, which can relieve the symptoms of pericardial tamponade, reduce the pressure in the pericardial cavity, and reduce the compression of the heart by pericardial effusion, thereby improving the symptoms of patients.

[0003] Existing pericardial drainage tubes are usually set as straight tubes, and the straight tubes still have the following problems in the existing technology:

[0004] Due to the complex anatomical structure of the pericardial cavity, there may be scars, adhesions or tissue barriers, which will affect the placement and drainage effect of the drainage tube. The straight drainage tube may not be able to effectively bypass these obstacles, resulting in poor drainage and affecting the timely discharge of pericardial effusion;

[0005] The straight drainage tube may cause greater discomfort and pain to the patient during the insertion and placement process, with greater friction and irritation to the skin and tissues, which may cause discomfort to the patient and even affect the patient's sleep and rest;

[0006] Pericardial effusion may contain viscous substances such as blood, pus, and fibrinogen, which are likely to deposit and coagulate in the straight drainage tube, resulting in blockage of the drainage tube. The blocked drainage tube not only cannot effectively drain the fluid;

[0007] The straight drainage tube is easily affected by external forces in the body. For example, when the patient moves, coughs or changes body position, the drainage tube may fall off or shift.

[0008] Therefore, we make improvements and propose a pericardial drainage tube. Summary of the Utility Model
