Description

Apparatus for fixing catheter comprising vertical fixing element

The present invention relates to a catheter fixing device, specifically, a catheter fixing device for simultaneously fixing in the horizontal and vertical direction the catheter inserted in the vertical direction of the skin surface of the patient to discharge the fluid from the inside of the patient's body to the outside It is about.

Paracentesis is a surgical procedure to remove liquids. When liquid is filled in a limited space, a medical instrument with a hollow needle such as a catheter is inserted into the patient's body. It is a procedure to remove the body fluids to alleviate the pain of the patient and at the same time to use for diagnosis of the liquid. Procedures or invasive procedures involving puncture using a catheter vertically inserted into the patient's skin surface include, for example, abdominal paracentesis, thoracentesis or amniocentesis.

Multiple puncture is a procedure or invasive procedure in which a needle is inserted into the abdominal cavity to remove the ascites. It is performed to diagnose the cause of a new ascites or to check for complications when the amount of the ascites suddenly increases. Or for therapeutic purposes for refractory ascites control. Therefore, it can be performed to acquire and analyze body fluids to identify or determine the cause of a substance present in the abdominal cavity for diagnostic purposes, and to remove a large amount of ascites in the abdominal cavity for therapeutic purposes. In addition, the puncture of the pleural effusion is a procedure or an invasive process for releasing the pleural effusion in the pleural cavity and examining the pleural effusion to clarify the cause or to treat symptoms such as dyspnea by removing the pleural effusion. In addition, amniotic fluid puncture is a procedure or invasive process in which amniotic fluid is taken as a sample to diagnose fetal disease before birth. Cells that are dropped from the fetus and suspended in amniotic fluid can be cultured. Can be used. In addition, a mother with severe amniotic fluid (hydramnios) accompanied by dyspnea may be used to remove an appropriate amount of amniotic fluid using amniocentesis.

Such a procedure or invasive procedure generally involves disinfecting a patient's material collection site to prevent infection, then inserting a syringe into the site and taking a sample material. On the other hand, if a large amount of sample material (drainage) is required for the purpose of the procedure or invasion, the fluid tube is connected to a catheter (or cannula) composed of a discharge tube (skin insert). The sample material is collected by connecting to a collecting container. However, if such a large amount of sample material is to be taken, the procedure or invasive process takes a long time, the catheter needs to be fixed firmly to the body fluid discharge site of the patient for a long time. If the catheter is not securely fixed on the patient's body fluid outlet, the sample material may not be properly discharged and may cause fatal infection or injury to the patient.

A catheter is a medical device that is generally inserted into the patient's body and used to inject a liquid therapeutic drug or the like, and to discharge the body fluid to the outside. Such a catheter may need to remain inserted into the patient's skin while the patient is being treated as needed. In this case various methods are known for maintaining and maintaining the catheter at the site of treatment during the procedure or invasion of a patient.

The conventional method of fixing the catheter is, for example, there is a method of tying a portion of the catheter exposed to the outside of the human body with a surgeon fixed to the human body, and covering the portion with a dressing. However, there is a problem that the catheter is pushed out of the human body when the patient moves or exchanges the dressing because the catheter cannot be firmly fixed by the surgeon.

In addition, another conventional method is a method of fixing to the skin using a skin adhesive means such as a band-aid so that the catheter does not move in the state inserted into the human body. However, this requires, for example, a step of cutting the band-aid appropriately in contact with the skin in order to fix the catheter during the procedure or invasion, and it is cumbersome to attach the cut band-aid to the skin to fix the catheter. By subsequently removing the bandage itself, the catheter attached to the skin of the patient may inadvertently move. In addition, there was a problem that can cause side effects such as skin diseases in the process. For example, there may be contaminants in the bandages used in the catheter insert that may potentially infect the patient. In addition, according to the fixing means, since the control of the catheter movement is impossible, complications related to catheter operation such as phlebitis, infiltration and catheter migration may be caused.

In particular, conventional methods for anchoring the catheter require prolonged bodily fluid discharge, for example in the case of invasive processes such as multiple punctures, pleural punctures, or amniotic punctures, whereby the conventional fixation means may cause the catheter to be horizontal and Failure to hold it firmly in the vertical direction, the catheter can rock or move on the skin surface, and such movement can, if desired, cause fatal injuries inside or outside the patient's skin. Accordingly, the present inventors firmly fix the catheter inserted into the vertical direction of the surface of the patient's skin to discharge the fluid from the inside of the patient's body to the outside, and at the same time medical assistance that can minimize contamination of the body fluid discharge site The device was invented.

In order to solve the conventional problems as described above, the present invention is inserted into the vertical direction of the surface of the patient's skin catheter discharging fluid from the inside of the patient's body to the horizontal and vertical direction of the patient's skin surface It is to provide a catheter fixing device for fixing.
