Description

CENTRAL VEIN CATHETER SET COMPRISING CENTRAL VEIN CATHETER WITH ADHESIVE SURFACE AND CATHETER GUIDER}

The present invention relates to a central venous catheter with an attachment surface, and more particularly, to a central venous catheter designed to ensure that the catheter adheres well to the body part after the catheter is placed in the vein and that the catheter and the connecting tube are not broken.

The central venous catheter acts as a channel for intravenous fluids or medications.It is usually performed during surgery, in an intensive care unit or an emergency room, and it is necessary to reduce intravenous pressure or to maintain a long intravenous catheter, The central venous catheter is performed when it is necessary to enter the formulation easily and in a short time.

The catheter is inserted into the vein in the subclavian vein, jugular vein, or large saphenous vein. For example, the procedure is performed in the subclavian vein. For example, a relatively thick syringe is inserted into the subclavian vein and then venous blood. Confirm that the needle is inserted into the subclavian vein, remove the syringe, leaving only the next needle, insert the catheter guider into the needle and remove the needle again while leaving the catheter guider. The procedure is completed by inserting the catheter into the vein along the catheter guider and removing the catheter guider with the catheter left.

Catheter insertion into the jugular vein or femoral vein is performed in this way, which is called Seldinger's technique.

However, the existing catheter is fixed with a band-aid after the catheter is inserted in this way, or the tip is sealed with a thread to prevent the catheter from falling out.If it is attached with a band-aid, it may fall off and a gap is formed between the band-aid and the catheter tip. Contaminants can enter the site where the catheter is inserted into the skin, which can cause infection in the catheter insertion area of the skin. If the catheter is sealed together with the skin, it can be firmly fixed but inflamed in the suture area. It also has the disadvantage of suffering patients. In addition, the conventional catheter is made of a hard material of the connecting tube, so that the pipe and the connecting tube may be well bent, which may cause a problem when the fluid or drug is introduced into the catheter. In particular, if a small amount of the important drug is accurately administered through the machine, the drug may not be properly injected, which may seriously affect the patient's condition.

On the other hand, the existing catheter guider (or guide wire) used to insert the catheter has a complicated structure is difficult to manufacture domestically, depending on imports, and the unit price is also expensive disadvantage.

The present invention provides a central venous catheter with an attachment surface to fix the catheter well to the body part of the patient and to prevent the bending portion of the connection tube and the tube to meet the problem as described above. The purpose.

In addition, the present invention has a simple structure to solve the problems of the catheter guider as described above, but the production cost is low, compared to the conventional guide wire performance does not lag behind the catheter guider can be inserted without damaging the vessel wall It aims to provide.
