Description

[0001] Pigtail catheter with cleaning function [0002]

The present invention relates to a pigtail catheter having a cleaning function, and more particularly, to a pigtail catheter having a cleaning function, and more particularly, to a pigtail catheter having a cleaning function capable of selectively removing foreign substances generated in a drainage pipe for discharging blood or body fluids To a pigtail catheter having a cleaning function.

In general, a drainage catheter is a multipurpose catheter for peritoneal drainage of unnecessary or harmful body fluids caused by a disease or accident, such as pericutaneous nephrostomy (PCN), percutaneous catheter drainage (PCD), PTBD (Percutaneous transhepatic biliary drainage).

The PCN (Perocutaneous Nephrostomy) is a method in which urine is drained by inserting a tube directly into the kidney through a flank.

Percutaneous catheter drainage (PCD), which is called percutaneous catheter drainage, is a method of delivering the drug to the outside of the body because it does not disappear even after prescribing antibiotics as a drug in the abscess. After the tube through the skin to the liver abscess, .

On the other hand, percutaneous transhepatic biliary drainage (PTBD), which is a percutaneous transhepatic biliary drainage technique, is a procedure in which a drainage tube is inserted into the bile duct from the outside of the body using a fluoroscopic image of the radiation, thereby releasing bile, which is not normally discharged, out of the body. The procedure is performed when the biliary tract becomes narrow and normal drainage is difficult.

In general, in percutaneous spinal choledochal drainage, after the procedure, the drainage tube is clearly visible in the bile duct, and the bile is drained through the drainage tube to check whether drainage is successful. Then, the patient is transferred to the room and the amount of bile It will see the progress. The faster the symptom improvement of the patient, the faster the treatment of the disease, and the more common the time of the general invasive procedure, which is common to all procedures performed for treatment or diagnostic purposes, Opportunities for infection, a typical complication, increase. In the case of biliary drainage, the risk of infection is high because of the possibility that the bile itself is already infected or contaminated by intestinal bacteria. Therefore, development of a catheter that can drain the bile quickly and efficiently is required.

As described above, a so-called pigtail catheter is used as an important surgical instrument used for various drainage procedures. The peak tail catheter has a round annular shape in which the tip of the elongated tube is curled, A large number of drainage holes capable of drainage are formed.

Such a conventional pigtail catheter has various structures for improving bile drainage as disclosed in Korean Patent Laid-Open No. 10-2012-0041067.

However, in the conventional pigtail catheter, the concentration, the fibrous substance, the protein or the cell are aggregated in the hollow or the drain hole during the drainage process, and the drainage hole and the hollow in the tubular body are blocked, . In order to solve this problem, the pigtail catheter is cleaned to smoothly drain the liquid. However, there is a disadvantage in the procedure that the pigtail catheter must be separated from the body and then cleaned. In the process of separating the pigtail catheter from the body, There is a problem that a pneumothorax may occur due to the inflow air.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above problems, and it is an object of the present invention to provide a pigtail catheter that can clean the inside of a drainage tube without separating a portion to be cleaned from the pigtail catheter body, And it is an object of the present invention to provide a pigtail catheter that prevents air from flowing into the inside of the main body when cleaning the inside of the main body.

To achieve the above object, according to the present invention, there is provided a blood transfusion apparatus comprising a transfer unit formed to penetrate a blood transfer conduit through which blood or body fluids are transferred, and a blood drain or fluid outlet communicating with the transfer channel, An enclosing body; A drain pipe connected to a front end of the main body and having an elastic material and forming a hollow along a longitudinal direction of the main body and having a plurality of through holes formed at a closed front side to draw blood or body fluids into a hollow; A wire embedded in the main body and the drain pipe and having self-elasticity; A foreign matter removing member which is provided at a front end of the wire and is located at a hollow front end portion of the drain pipe and moves backward by the wire which is selectively moved backward by a user's operation to clean the hollow interior of the drain pipe; The wire is disposed on the wire so as to be positioned in the transfer passage. During the drainage, the blood or body fluids flowing into the one end of the main body through the drain pipe are prevented from being transferred to the other end of the main body. A transfer preventing member having two functions for preventing air inflow; And a drain opening and closing member provided in the main body adjacent to the drain portion and selectively opening and closing the drain portion while being slid from the main body to the front end and the rear end by an external force, the pigtail catheter having a cleaning function do.
