Peritoneal drainage catheter

Abstract

The invention relates to the technical field of medical catheters and specifically relates to a peritoneal drainage catheter. The peritoneal drainage catheter includes a drainage tube communicating with a guide tube. The guide tube is communicated with a negative drainage bottle. The front tube wall of the drainage tube is provided with three rectangular gaps, wherein two of the rectangular gaps are arranged symmetric about an axial lead and the other rectangular gap is disposed in the middle position of the two rectangular gaps symmetric to each other. A connection band is arranged between the rectangular gaps and the guide tube uniformly. The connection band is arc in shape. The inner side of the connection band is connected with a guide board. The middle part and the rear part of the drainage pipe are provided with drainage holes arranged irregularly and having different shapes. The front outer wall of the guide pipe is sleeved with an air bag communicating with the guide pipe. The front part of the guide pipe is arranged in the guide pipe. The tail part of the guide pipe is arranged outside the guide pipe. By the design of the rectangular gaps and the drainage holes arranged irregularly and having different shapes of the drainage pipe, the catheter is not easy to get blocked by blood clots, necrotic tissues and the like, so that drainage smoothness is ensured.

Description

technical field [0001] The invention relates to the technical field of medical catheters, in particular to an abdominal cavity drainage catheter. Background technique [0002] Drainage tubes are very common in the medical field. Drainage tubes are used to insert into the patient's body to drain waste fluid, blood, flushing fluid, necrotic tissue, etc. from the patient's body. In clinical abdominal surgery, for patients with more ascites, such as patients with liver cirrhosis, drainage tubes are needed for drainage. Currently, the drainage tubes used clinically are composed of drainage holes, catheters, and drainage holes. There are the following defects in the method: the drainage tube is easily blocked by blood clots, necrotic tissue, etc., resulting in poor drainage; the drainage tube cannot be fixed, and it is easy to slip; the position of the drainage tube in the abdominal cavity is not easy to determine.
