Description

A flushable peritoneal drainage tube

technical field

The utility model relates to the technical field of medical instruments, in particular to a flushable abdominal cavity drainage tube.

Background technique

Most surgical patients, especially patients with acute necrotizing pancreatitis, pancreatic abscess, liver abscess, abdominal abscess, etc., need to indwell the abdominal drainage tube for a period of time after surgical treatment, so that the abdominal cavity can be drained in time after the operation. Effusion and necrotic tissue are drained and flushed to prevent infection and promote the healing of the lesion. If the drainage is not smooth, it is difficult to monitor the change of the condition after surgery, which may easily lead to postoperative infection, postoperative anastomotic leakage and other symptoms, and even lead to surgical treatment failure. . At present, the drainage tubes used clinically include simple drainage tubes and drainage tubes with flushing function, but both types of drainage tubes are prone to blockage of the drainage port, resulting in poor drainage. Although flushing and drainage can be carried out at the same time, because the drainage hole is small, it is easy to be blocked by the drainage material, and the outlet of the flushing channel is set at the top of the drainage tube, close to the drainage port, and the flushing fluid is not fully cleaned from the abdominal cavity. The negative pressure of the mouth is drawn out, and the problems of poor drainage and incomplete flushing often occur.

Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

Referring to Figures 1-3, a flushable peritoneal drainage tube includes a drainage tube 1 and a flushing tube 2, the flushing tube 2 is fixed on the inner wall of the drainage tube 1, and the rear end of the flushing tube 2 is separated from the rear end of the drainage tube 1. The front end of the flushing tube 2 protrudes from the drainage port 11 at the front end of the drainage tube 1. The front end of the flushing tube 2 is evenly provided with a flushing liquid outlet 21. The mouth 11 is provided with a side flushing liquid outlet 22, the side flushing liquid outlet 22 and the flushing liquid outlet 21 are both circular and the diameter of the side flushing liquid outlet 22 is smaller than the diameter of the flushing liquid outlet 21, and the front end side of the drainage tube 1 The wall is provided with a side drainage port 12, and the rear end of the drainage tube 1 is provided with a valve 14, and the drainage tube 1 at the front end of the valve 14 is connected with a balloon 13, and the inside of the balloon 13 communicates with the inside of the drainage tube 1.

Wherein, the front end of the flushing pipe 2 protrudes 15 mm from the drainage port 11 .

Wherein, a liquid injection joint 23 is connected to the rear end of the flushing pipe 2, and a sealing plug 24 is blocked on the liquid injection joint 23.

Wherein, the outer wall of the drainage tube 1 is provided with a length scale line along the length direction of the drainage tube 1, through which it is convenient to observe the depth of the flushable abdominal drainage tube inserted into the abdominal cavity.

Wherein, the drainage tube 1, the balloon 13 and the flushing tube 2 are all made of silicone rubber, which is non-toxic and soft in texture, and the flushing tube 2 will not damage the abdominal cavity when the flushable abdominal drainage tube is inserted into the abdominal cavity. Injury to internal organs.

A specific application of this embodiment is: insert the front end of the flushable peritoneal drainage tube into the abdominal cavity through an incision, open the sealing plug 24 on the liquid injection joint 23 at the rear end of the flushing tube 2, and inject the flushing liquid through the liquid injection joint 23. The flushing liquid is injected into the peritoneal cavity from the flushing liquid outlet 21 at the front end of the flushing tube 2 to clean the abdominal cavity, and a small amount of flushing liquid is ejected from the side flushing liquid outlet 22 at the drainage port 11. ㎜, the flushing liquid flowing out from the flushing liquid outlet 21 will not immediately be drawn out through the negative pressure of the drainage port 11, so that the flushing liquid can wash the inside of the abdominal cavity in a large range and the flushing effect is good. Connect the end of the drainage tube 1 to the negative pressure, and the flushing liquid in the abdominal cavity The drainage port 11 at the front end of the drainage tube 1 and the side drainage port 12 are drawn out by negative pressure. During the flushing and drainage process, the flushing fluid sprayed from the side flushing liquid outlet 22 flushes the drainage port 11 at the front end of the drainage tube 1 to avoid drainage. The mouth 11 and the side drainage port 12 are blocked by the drainage material. If a large blood clot or abscess blocks the drainage port 11 and the drainage is not smooth, close the valve 14 and squeeze the balloon 13. When the balloon 13 is squeezed, the balloon 13 The liquid inside is discharged from the drainage port 11, and the blockage blocked in the drainage port 11 is washed out, the drainage tube 1 is simply and quickly cleared, and then the valve 14 is opened to continue drainage. The flushable peritoneal drainage tube has a simple overall structure and is easy to use.
