Abstract

The utility model belongs to the field of medical apparatus and provides a brand-new abdominal drainage tube which comprises a drainage needle and a drainage soft pipe. The top end of the drainage soft pipe is connected with the drainage needle. A tee joint is arranged in the rear of the drainage soft pipe and connected with a drainage pump through the tee joint. A filtering net is arranged on a needle hole of a tip of the drainage needle. With the drainage pipe of the structure, when being used, the drainage needle is directly arranged in the abdominal cavity of a patient and the drainage pump is started to provide negative pressure. Thus, liquid in the abdominal cavity can be pumped into the drainage soft pipe through the drainage needle. As the filtering net is arranged on the needle hole, solid matter particles in the abdominal cavity can be effectively prevented from entering into a needle tubing and the drainage pipe is prevented from being blocked. Thus, pain of the patient is relieved, medicine can be conveniently applied, flushing is convenient and physical health of the patient is favored.

Description

abdominal drainage tube

Technical field:

The utility model belongs to the field of medical instruments, in particular to an abdominal cavity drainage tube.

Background technique:

After abdominal surgery, especially after hepatobiliary surgery, a peritoneal drainage tube is required to drain the remaining blood and fluid in the abdominal cavity. At the same time, the intraperitoneal drug needs to be anti-inflammatory and flushed frequently. At present, the drainage tubes commonly used in clinical practice are mostly rubber circular tubes with uniform thickness, and are generally used as a single tube. Both drug administration and drainage are carried out in the same tube. , and the medicine is often taken away by the drained fluid directly after being sent into the drainage tube, which fails to achieve the purpose of flushing and anti-inflammation. Blood clots and other tissue debris, once these solid substances enter the drainage tube, they will cause the blockage of the drainage tube, which brings great inconvenience to the recovery of the patient, and also brings a lot of inconvenience to the medical staff.

Contents of the invention

Aiming at many problems existing in the existing abdominal cavity drainage tube, the utility model provides a brand new abdominal cavity drainage tube, which includes a drainage needle and a drainage hose. , and a drainage pump is connected through a tee, and a filter screen is arranged on the pinhole at the tip of the drainage needle. With the drainage tube of this structure, when in use, the drainage needle is directly placed in the patient's abdominal cavity, and the drainage pump is turned on to provide negative pressure, so that the liquid in the abdominal cavity can be sucked into the drainage hose through the drainage needle. The filter screen can effectively prevent solid particles in the abdominal cavity from entering the needle tube, avoid the blockage of the drainage tube, reduce the pain of the patient, facilitate drug administration and flushing, and benefit the health of the patient.

The utility model adopts the following technical solutions: a brand-new abdominal cavity drainage tube, including a drainage needle and a drainage hose, the top of the drainage hose is fixedly connected with a drainage needle, and the rear part of the drainage hose is provided with a tee, which is connected with a drainage pump;

With the drainage tube of this structure, when in use, the drainage needle is directly placed in the patient's abdominal cavity, and the drainage pump is turned on to provide negative pressure, so that the fluid in the abdominal cavity can be sucked into the drainage hose through the drainage needle. There is a three-way in the inner part. When anti-inflammatory or flushing of intraperitoneal administration is required, just turn off the drainage pump and inject medicine or flushing solution into the drainage hose through the three-way. At this time, there is no function of the drainage pump. The liquid can be easily sent into the patient's abdominal cavity, and will not be sucked out by the pump along with the drained liquid. After the administration or washing is completed, close the administration port on the tee and restart the drainage pump.

The drainage needle is provided with a needle seat, and a filter screen is provided on the pinhole of the needle tip of the drainage needle. Due to the existence of the filter screen, it can effectively prevent the solid matter particles in the abdominal cavity from entering the needle tube, avoiding the blockage of the drainage tube and reducing the patient's life expectancy. Pain is beneficial to the patient's health.

To sum up, when the drainage tube with this structure is used, the drainage needle is directly placed in the patient's abdominal cavity, and the drainage pump is turned on to provide negative pressure, so that the fluid in the abdominal cavity can be sucked into the drainage hose through the drainage needle. The filter screen on the needle hole can effectively prevent the solid particles in the abdominal cavity from entering the needle tube, avoid the blockage of the drainage tube, reduce the patient's pain, facilitate drug administration and flushing, and benefit the patient's health.
