FIELD OF THE INVENTION The present invention relates to a dressing material for fixing a catheter.

[0002]

2. Description of the Related Art Therapies for long-term catheter placement such as central venous infusion and epidural anesthesia are increasing year by year. At the same time, complications due to infection, such as sepsis associated with catheter placement, have become a major problem. Various dressings have been developed to secure the catheter while preventing this infection.

For example, Japanese Utility Model Laid-Open No. 2-141435 describes a dressing material in which a transparent or semi-transparent coating film is coated with an adhesive material. In this dressing material,
Since the catheter insertion part can be observed through the transparent or translucent film, it is not necessary to remove the dressing material for observing the catheter insertion part. A disinfectant ointment is generally applied to the insertion part of the catheter to prevent infection, but since this dressing material does not have a liquid-absorbing capacity, the disinfectant ointment leaks out of the dressing material, which may cause It may peel off.

JP-A-62-16763 describes a dressing material in which a pad is laminated on a coating film. With this dressing material, the pad can absorb the applied disinfectant ointment to prevent the ointment from flowing and leaking out, but since the catheter insertion part is covered with the pad, dressing is necessary to observe the catheter insertion part. I have to peel off the material.

Japanese Patent Laid-Open No. 59-156344 describes a wound protector in which a compartment is provided on a hollow pad, but the structure is complicated and the manufacturing cost is high. Furthermore, since this protector adheres to the skin only through the pad, the fixing strength is insufficient for fixing the catheter. Japanese Patent Application Laid-Open No. 3-49757 discloses an opening located above a wound and a ventilation means for controlling leakage of bodily fluid by following a path passing through the opening. Breathable absorbent bandages are provided which are provided with absorbent means for absorbing incoming body fluids. This bandage has a complicated structure and is expensive to manufacture. Also, the catheter insert cannot be observed through this bandage. Further, the disinfecting ointment applied to the insertion part of the catheter easily transfers to the absorbent isolated from the insertion part.

[0006]

SUMMARY OF THE INVENTION According to the present invention, the insertion portion of the catheter can be observed from the outside, the disinfection ointment applied to the catheter insertion portion can be prevented from leaking, and the structure is simple. An object of the present invention is to provide a dressing material for fixing a catheter that does not require a manufacturing cost.

[0007]

In order to solve the above-mentioned problems, the present invention provides a covering film, an adhesive layer laminated on one surface of the covering film, and a liquid-absorbent pad adhered to the adhesive layer. In the dressing material for fixing a catheter, the covering film is transparent or translucent, and the absorbent pad material has a through opening. ..

[0008]

[Operation and effect] In the dressing material of the present invention,
Since the coating film is transparent or translucent and the pad material has a through opening, the catheter insertion part can be observed from the outside without peeling off the dressing material. Further, since the absorbent pad material having a through hole is used,
The disinfecting ointment applied to the catheter insertion portion is not forcibly absorbed and removed, and the fluidized ointment is absorbed by the pad material and does not leak outside the dressing material.
