報）。[0003] Examples of such medical devices include catheters used for peritoneal dialysis and associated components. In particular, in the case of peritoneal dialysis, extreme caution is necessary because the intraperitoneal cavity has a low protective function against bacterial invasion. To perform peritoneal dialysis, a catheter for connecting the intraperitoneal cavity and the outside of the body is installed, and a dialysate container is connected to the catheter via a connector and a tube to supply and discharge the dialysate. In recent years, in the case of continuous portable peritoneal dialysis (CAPD), which has become popular, the dialysate container (bag) is usually changed four times a day, but the connector is disconnected each time it is changed. There are many opportunities for bacteria to enter. In addition, if the connection is not completely sealed during connection, bacteria may enter through the gap, and the occurrence of peritonitis due to bacterial infection is a major problem in performing peritoneal dialysis. In order to prevent bacteria from entering when the connector is released, measures such as disinfection of the connector with a disinfectant and sterilization by ultraviolet irradiation or heating are performed. A method is used in which the surrounding area is covered with a disinfecting solution with a sponge or the like. In this case, it is necessary to cover the periphery of the sponge layer with a hard cover in order to prevent leakage of the disinfectant and to protect the connector. The present applicant uses a cylindrical member having a liquid absorbing material layer that has absorbed a disinfecting liquid, which is a part of a disinfecting container for disinfecting the connector part, as a cover of the connector connecting part, It has been proposed to mount a cover on the cylindrical member to protect the connector (Japanese Patent Publication No. 63-50022).

ジ部によって結合することができる。The present invention provides a cylindrical coating material for covering a connector of a medical device, which has a connector at a tube connecting portion and a liquid absorbing material layer containing a germicide on an outer surface and a bactericide on an inner surface. And the protective cover of the cylindrical covering material having a space for accommodating the upper cover and the lower cover, the container comprising two openable and closable plastic upper and lower lids. The side walls have slit holes for fitting, receiving and fixing the flange of the cylindrical covering material, and the side walls of the upper lid and the lower lid have holes of substantially the same diameter as the inserted medical tubes. The present invention relates to a protective cover for a connector of a tube connecting portion of a medical device, which has a cutout portion capable of forming a notch.
As described above, the present applicant discloses in Japanese Patent Publication No. 63-50022 a device useful for disinfecting a connector of a tube connecting portion of a medical device and protecting the connecting portion after the connector is connected. In the device, a cylindrical covering material having a liquid absorbing material layer containing a bactericide on the inner surface,
It is composed of a lid material attached to one end of the cylindrical member, and a protective cover for housing the cylindrical member after connecting the connector. In this device, after the connector is connected, the periphery of the connector is surrounded by a cylindrical covering material having a liquid-absorbing material layer containing a bactericide, which is a part of the device, and further around the connector,
I am doing protection with a hard cover. Furthermore, to make it easier to grip the cylindrical coating when attaching and detaching the lid,
It is preferable to provide a flange on the outer surface of the cylindrical covering material on the side opposite to the side on which the lid member is mounted. The hard protective cover not only protects the cylindrical covering material but also serves to fix the connector and the cylindrical covering material so that they do not shift, so that the protective cover covers the connector at both ends. At the same time, the flange provided on the cylindrical covering material is fixed by a flange fixing portion provided inside the protective cover. However, since the conventional protective cover accommodates the entire cylindrical covering material, its inner diameter must be larger than the flange provided on the cylindrical covering material, and a flange fixing portion is provided inside. Therefore, there is a problem that the diameter becomes large and bulky. In particular, this problem has been an important problem to be solved when carrying a connector part like the above-mentioned continuous portable peritoneal dialysis (CAPD). In the present invention, as described above, since the flange of the cylindrical covering material is housed in the slit of the protective cover, the inner diameter of the protective cover may be substantially the same as the outer diameter of the cylindrical covering material, which is smaller than the conventional one. Can be made more compact. Further, since the flange of the cylindrical covering material is fixed by being inserted into the slit of the protective cover, a complicated means for fixing the flange inside the protective cover for fixing both is used as in the related art. Is not required, so that the structure of the protective cover is not only simplified, but also the flange is inserted into the slit and fixed, so that it is more firmly fixed. Further, the upper lid and the lower lid of the present invention only need to have a shape that can accommodate the cylindrical covering material and the connector when both are closed, and correspond to the cylindrical covering material and the connector. Those having the same shape as the semi-cylindrical portion are preferable. When the upper and lower lids are of the same circular semi-cylindrical shape, slits can be provided in both the upper and lower lids, and the flanges can be stored in both slits. , Can be more compact. The protective cover of the present invention may be variously conceived.In particular, the synthetic resin such as polypropylene, polyethylene, and polystyrene is used. It is preferable to manufacture them integrally. Particularly, polypropylene and polystyrene are preferable because a durable hinge can be formed.
When it is desired to impart flexibility, a polypropylene blended with an ethylene-propylene-diene terpolymer is preferred. However, the material of the protective cover may be metal or the like, and the upper lid and the lower lid can be joined by a hinge provided separately therefrom.

The present invention is not limited to this, and can be widely used as a protective cover for a tube connection portion of a medical device that needs to maintain the inside in a sterile state.
