Description

Drainage tube assembly

Technical Field

The utility model belongs to the technical field of the medical instrument technique and specifically relates to a drainage tube subassembly.

Background

The development of modern medicine takes rapid rehabilitation as a future development direction, the tissue trauma is small, the disease recovery is rapid, the pain of patients is little, the complication incidence rate is low, and the development is a commonly pursued target and direction in the modern medical field. Liquid focus of every part of human body is an important factor for determining whether diseases can be rapidly recovered, especially malignant liquid focus is one of main causes of serious complications such as body infection, septicemia, major hemorrhage, DIC and the like, and both traumatic liquid focus and postoperative liquid focus should be thoroughly drained and removed.

At present, the removal route of the liquid focus comprises external drainage, internal self-absorption or organization and packaging to form pseudocyst and calcific focus, wherein the external drainage is a crucial part, and most of liquid needs to be drained before the body can realize self-further absorption or organization. Especially malignant liquid focus, can recover health rapidly after reaching nearly one hundred percent drainage to avoid serious complications, such as effusion generated by infectious purulent focus, malignant tumor hydrothorax and ascites, postoperative pancreatic fistula, biliary fistula, intestinal fistula and the like. If the drainage is not timely cleared, bacteremia, sepsis and infectious shock can be caused by infectious pyogenic lesions, the malignant pleural effusion and ascites can cause the rapid and extensive dissemination and transfer of tumors in the thoracic cavity and the abdominal cavity, severe secondary peritonitis caused by fistulae enterofistula can finally cause infectious shock and multiple organ failure, and the pancreatic juice generated by pancreatic fistula is accumulated around arterial vessels to corrode the vessel wall and possibly cause severe celiac hemorrhage, thereby causing hemorrhagic shock in a short time and endangering life.

The existing drainage device and negative pressure drainage device have the defects of more restriction conditions and incomplete drainage, for example, the most common thoracic drainage tube in clinical medical treatment completes drainage work by communicating the inside of a focus and the outside of a body cavity, and if liquid is in a deeper and lower position in a patient body or a position with smaller liquid amount, the thoracic drainage tube cannot achieve a good drainage effect; for another example, the negative pressure single-cavity drainage tube has the problems that the negative pressure is too low to absorb body fluid or the negative pressure is too high to easily absorb surrounding tissues, so that the drainage is insufficient and the drainage effect is poor.
