Description

Medical catheter {MEDICAL CATHETER}

The present invention relates to a medical catheter, and more particularly, to a medical catheter capable of continuously supplying jelly so as to alleviate pain during insertion into the human body in a medical catheter such as a Foley catheter or Levin tube.

Various catheters are used for medical purposes. A catheter is a thin tube made of medical materials, and is a general term for a catheter inserted into the human body for the purpose of treatment, surgery, or surgery. Representative medical catheters include Foley catheter and Levin tube.

Foley catheter is a device that is inserted into the bladder to discharge urine to the outside. It is used inside and out.

There are various types of Foley catheters, but they are largely divided into 2-lumen and 3-lumen catheters. The two-pronged catheter consists of a tube for urine discharge and a tube for balloon inflation, and the three-prong catheter is provided with a tube for urine discharge and a tube for balloon inflation, plus a tube for injection of a washing solution and a drug.

Levin tube, also called nasogastric tube or L tube, is a catheter for stomach or duodenum mainly inserted through the nose. For example, in the case of gastric insertion, it is used for the purposes of decompression, washing blood or secretions, analysis of gastric juice, nutrition, and administration.

Referring to FIG. 1 , it can be seen that the Foley catheter 100 is inserted and placed in the bladder (B). 2 is a schematic diagram of a two-pronged catheter. An opening 102 is provided at one end side of the tube body 101 of the Foley catheter 100, and a balloon 103 for placing the catheter in the bladder is provided. A urine discharge port 104 and a balloon port 104 are provided at the other end of the tube body 101 . Urine is discharged to the outside through the urine discharge port 104 , and a fluid such as saline is supplied through the balloon port 104 to inflate the balloon 103 .

Inserting various medical catheters such as Foley catheter or Levin tube into the human body may cause pain to the patient. For example, in the case of Foley catheter insertion procedure, an operator such as a doctor or nurse must insert a Foley catheter through the urinary tract to the bladder, and not only requires sterilization and sterilization, but also causes great pain to the patient depending on the operating environment or conditions. . For this purpose, sterile jelly is usually applied to the outer surface of the Foley catheter and then the procedure is performed. In particular, if the urethra is long like men, the jelly peels off during the procedure, which may cause pain to the patient. In addition, there is a problem that the operation is difficult and the surrounding environment is polluted due to the jelly.

In order to solve this problem, various techniques such as improvement of materials and introduction of insertion devices have been proposed (see Patent Documents 1 and 2). Nevertheless, the discomfort and cumbersome procedure were still there, and because it did not provide a sufficient pain relief effect to the patient, a catheter or insertion device of a new material was not widely used. Therefore, it has been required to develop a medical catheter that can be used more easily and conveniently by the operator and can reduce the pain during catheter insertion from the patient's point of view.
