In the catheter fixation method commonly used to fix the inserted catheter, the catheter is inserted into a part of the body and the tape is attached to the catheter and the patient's skin to fix the catheter, followed by hemodialysis, drug injection, and discharge of the contents. The liquid is measured.

When fixing the catheter using tape as described above, when the catheter is inserted into the patient's body part and the tape and the catheter are directly attached to the patient's body, the catheter flows and a wound occurs at the insertion part where the catheter is inserted. There was a problem that the secondary infection occurs through the bacteria penetrated through.

In addition, when adjusting the fixed part after fixation, the tape and the catheter are attached directly to the patient's body after removing the tape and adjusting the fixed part. Therefore, when adjusting the fixed part, the patient suffers and adjusts the resting position. There was a problem that causes psychological anxiety of the patient.

In addition, when the catheter is fixed by using a tape for a long time, there is a problem that a skin trouble occurs on the fixed part.

In order to solve the above problems, various catheter fixing devices have been proposed. As an example, 'Stat Lock' of CRBard, Inc. of America and 'Safety Lok' of BD, Inc. of USA are easy to disinfect the affected area and prevent twisting of the tube under the catheter. , Since only a specially manufactured needle can be fastened, there is a problem in that the catheter fixing device and the needle need to be purchased twice.

In addition, in the case of 'Multi Fix' of domestic Unimedics Co., Ltd., the tube is fixed to the needle instead of the needle, and the needle is fixed with tape as before. There was an issue that was difficult to see.
