technical field

The utility model relates to a drug injection flushing drainage tube with a balloon, which belongs to the technical field of medical instruments.

Background technique

Thoracic and abdominal puncture catheterization is a commonly used clinical treatment method, which is used to drain the effusion or gas in the pleural cavity and abdominal cavity, and perform normal saline irrigation and drainage or infusion of medicinal liquid into the pleural cavity or abdominal cavity. The traditional thoracoabdominal puncture and drainage device consists of a puncture needle and a drainage tube. When used, the puncture needle is inserted into the thoracic and abdominal cavity, and then a syringe is used to extract the fluid or gas in the thoracic and abdominal cavity. At present, a central venous catheter (minimally invasive) is also used. , Surgical chest tube and abdominal drainage tube etc. for continuous drainage of the thoracoabdominal cavity. Due to the above method, the drainage catheter is placed in the incision for a long time, and the catheter is too thin or too thick, which may easily cause the displacement, fall off and blockage of the drainage catheter, which will affect the comfort of the patient and the therapeutic effect. The incision trauma is too large, and the washing and injection is not convenient enough.

The utility model adopts the following technical scheme: a drug injection flushing drainage tube with a balloon, including a drainage main tube and a rear intubation tube, the rear end of the drainage main tube is socketed with the front end of the rear intubation tube, and the front end of the drainage main tube is A first balloon is arranged around the main drainage tube, a drainage bag is connected to the end of the rear intubation tube, a drug administration tube is provided on the top of the main drainage tube, and a connecting tube is provided on the bottom of the main drainage tube. One end of the tube communicates with the first balloon, the other end of the connecting tube is connected with the second balloon, and the second balloon is connected with a one-way valve through a Luer joint.

Further, the distance between the first balloon and the front end of the drainage main tube is 55-85 mm.

Further, the end of the drug delivery tube is used to connect with a syringe.

Further, the distance between the front end of the drug delivery tube and the front end of the drainage main tube is 15-20 mm.

Further, the angle between the front end of the drug delivery tube and the drainage main tube is 30-35°.

Further, the inner diameter of the drainage main pipe is 4-6 mm, and the outer diameter of the drainage main pipe is 7-9 mm.

Further, the end of the drainage main pipe is provided with a side hole, and the distance between the side hole and the end of the drainage main pipe is 20-30 mm.

The utility model has the advantages of simple structure, compact design and convenient use. According to the size of the incision, the first balloon at the front end of the drainage main pipe is filled with gas or liquid, so that the first balloon is full and the thoracoabdominal drainage catheter is stuck on the inner wall of the incision. , so that the thoracoabdominal drainage catheter will not slip out of the incision during use, and no additional sutures are required to fix it. The drug delivery tube can be flushed with physiological saline and infused with drug solution into the thoracic and abdominal cavity. The drainage main tube and the rear intubation tube are detachable It can be cleaned in time to prevent blockage.

detailed description

The utility model will be further described below in conjunction with the accompanying drawings.

As shown in Figure 1, a medicine injection flushing drainage tube with a balloon includes a drainage main tube 1 and a rear intubation tube 2, the rear end of the drainage main tube 1 is socketed with the front end of the rear intubation tube 2, and the inner diameter of the drainage main tube 1 is 4-6 mm, the outer diameter of the main drainage pipe 1 is 7-9 mm, the front end of the main drainage pipe 1 is provided with a first balloon 3 around the periphery of the main drainage pipe 1, and the distance between the first balloon 3 and the front end of the main drainage pipe 1 is 55-55 mm. 85mm, the end of the rear intubation tube 2 is connected with a drainage bag 6, which can also be used to connect a negative pressure balloon, a negative pressure bottle, and a drug delivery tube 4 is arranged on the top of the drainage main tube 1, and the front end of the drug delivery tube 4 is connected to the drainage main tube 1 The distance between the front end of the drug delivery tube 4 is 15-20mm, the end of the drug delivery tube 4 is used to connect the syringe, the angle between the front end of the drug delivery tube 4 and the drainage main tube 1 is 30-35°, and the bottom of the drainage main tube 1 is provided with a connecting tube 5, which is connected to One end of the tube 5 communicates with the first balloon 3, and the other end of the connecting tube 5 is connected with a second balloon 7, the second balloon 7 is used to fill the first balloon 3 with gas or liquid, and the second balloon The capsule 7 is connected to the one-way valve 8 through the Luer connector 9, and the end of the drainage main pipe 1 is provided with a side hole, and the distance between the side hole and the end of the drainage main pipe is 20-30 mm.
