Abstract

The utility model relates to a one-off ascitic fluid drainage and keeping tube, belonging to a clinical medical device, which mainly comprises a puncture needle, a keeping and drainage tube and a drainage bottle, wherein the keeping and drainage tube comprises two drainage tubes (5, 8) spliced and connected together, the front end of the drainage tube (5) is provided with a plurality of drainage micropores (3) and a wall-attaching gasbag (4), the wall-attaching gasbag (4) is connected with a wind injector (7) through a windpipe (6), and the puncture needle comprises a puncture needle core (2) and a needle tube (1). The utility model has rational structural design, a plurality of drainage micropores at the front ends of the drainage tubes avoid the plug of greater omentum and the educt in the ascitic fluid to the needle pole, the drainage tubes made of silica gel rubber have small pungency to the tissue, can be led to an abdominal cavity for a long term to drain the ascitic fluid at any moment, and inject anti infective or antineoplastic medicines into the abdominal cavity, thereby avoiding the pain brought by repeated puncture to patients, and the gasbag arranged on the drainage tube avoids the drainage tube from being separated during the keeping process, which can play a fixing function and can also prevent the exosmosis of the ascitic fluid.

Description

Disposable ascites drain indwelling tube

Affiliated technical field

This utility model belongs to the clinical treatment utensil, mainly proposes a kind of disposable ascites drain indwelling tube.

Background technology

Refractory ascites is the common complication of diseases such as liver cirrhosis, hepatocarcinoma, belly cavity tumor, brings great misery to the patient.The normal at present treatment measure of adopting has two kinds: the one, and repeated localised puncture, drain ascites; The 2nd, the external concentrated back of ascites drain feeds back vein or abdominal cavity.More the enforcement of these two kinds of methods is used entry needle to carry out abdomen and is worn, and in ascites drain feedback process, metal needle is left in the abdominal cavity, easy damaged peritoneum blood vessel and abdominal viscera, and needle body is not easy to fix.In addition, the syringe needle of single hole is often by the tolerant obstruction of intraperitoneal, thereby influences the extraction of ascites.

Summary of the invention

The purpose of this utility model promptly is to propose a kind of disposable ascites drain indwelling tube, solves existing problem in the existing drainage tube structure use.

This utility model adopts following means to finish its invention task: it mainly is made of puncture needle, indwelling drainage tube and drainage bottle, indwelling drainage tube is made of the drainage tube of two socket connections, anterior drainage tube and puncture needle inside pipe wall kiss are joined its front end and have been set a plurality of drain micropores, and be provided with attached wall air bag, attached wall air bag is connected with the inflation syringe by gas tube, and insert in the drainage bottle drainage tube rear end, rear portion; Puncture needle is made of puncture nook closing member and puncture needle tubing, and the puncture nook closing member is the sharp solid cylinder of front end; And be provided with control drain shutoff valve.

Use of the present utility model: before the use, check the unobstructed property and the air-tightness of total earlier, at first after routine disinfection, the local anesthesia, the puncture needle conventional method is penetrated the abdominal cavity, extract nook closing member, see have ascites to flow out after, the drainage tube front end is inserted the puncture needle tubing, insertion depth enters the abdominal cavity with attached wall air bag and is as the criterion, and to airbag aeration 10-20ml, avoids drainage tube to deviate from by airbag inflation pipe, extract the puncture needle tubing, it is withdrawed from along drainage tube, patch the back drainage tube of connection, Intraabdominal ascites is flowed in the drainage bottle along drainage tube at the front end drainage tube.

This utility model reasonable in design, a plurality of drain micropores of drainage tube front end have avoided that educt stops up pin hole in omentum majus and the ascites, the drainage tube of silica gel material is little to tissue irritation, can be left to the abdominal cavity for a long time, drain ascites at any time, and to intraperitoneal injection infection or antitumor drug, the misery of having avoided repeated localised puncture to bring to the patient, the air bag of drainage tube setting has been avoided deviating from of drainage tube in the indwelling process, can play fixation, can prevent that again ascites from exosmosing.
