Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application in Industry, 1-] The present invention relates to an insertion aid used when inserting an endoscope, a treatment instrument, etc. into a body cavity.

[Prior Art] Generally, treatment tools such as endoscopes and surgical forceps are inserted into body cavities via insertion aids. For this reason, as mucus and other substances adhere to the surface of insertion aids when these medical insertion instruments are pulled out of the body cavity, it is necessary to wash and disinfect the insertion aid after each use to keep the surface of the insertion aid clean. be.

[Problems to be Solved by the Invention] However, conventional insertion aids lack consideration for sterilization, and have the disadvantage that bacteria and mold grow in areas where cleaning and sterilization is forgotten.

The present invention was created in view of these 11 circumstances, and its 1.1 objective is to prevent bacteria from propagating or mold to grow in areas that have been forgotten to be cleaned and disinfected, and to maintain a hygienic environment. An object of the present invention is to provide an insertion aid for a medical insertion instrument that is easy to handle during storage.

Means and action for solving problem E] - In order to solve the problem described above, the present invention adds an anti-fungal and anti-bacterial agent to the insertion aid! 41. It is designed to prevent the proliferation of bacteria and the growth of mold.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 shows an embodiment in which the present invention is applied to a sliding tube 1. This sliding tube 1 has a guide hole 3 for inserting, for example, a flexible tube (not shown) of an endoscope into a body cavity. It is composed of a tube main body 2 and a cylindrical body 4 connected to one end of the tube main body 2.1.
The bipedal tube main body 2 has a flexible tube 6 attached to the outer circumference of the inner tube 5, and an outer tube 7 attached to the outer circumference of the flexible tube 6.
So he overturns it. 1-Iif One end of the flexible tube 6 is formed to be shorter than one end of the tubes 5 and 7, and the portions of the tubes 5 and 7 extending from one end of the flexible tube 6 are in contact with each other. The flexible portion 8 is formed by bending the tip opening edge of the flexible portion 8 slightly inward.

Further, the two tubes 5 and 7 are made of, for example, an extremely thin polyurethane resin, and the flexible tube 6 is made of, for example, a stainless steel band plate spirally wound.

On the other hand, the cylindrical body 4 has a connecting port 9 which the tube body 1 fits into 1t, and the outer periphery of the connecting port 9 is surrounded by a protective ring 10. A water-containing foamed resin 11 and a water-free foamed resin 12 are mounted inside the cylindrical body 4.

In addition, in this embodiment, the tube body 2 and the foamed resin 11
．． The entire surface of the cylindrical body 4 including 12 is coated with an antifungal and antibacterial agent 13. As the anti-fungal and anti-bacterial agent 13, for example, at least one of compound A1 represented by the formula, compound B1 represented by the formula, or compound C represented by the formula is used.

Note that G- above represents an aryl group substituted with at least one halogen atom, a lower alkyl group that is the same as or different from R, R', and R', and -OH on the pyridazine nucleus.
In addition, there is at least one substituent selected from halogen atoms, lower alkyl groups, and hydroxyl groups.

Compound A is produced by dispersing a compound represented by the formula % and a compound represented by the formula in a medium. If a compound represented by the formula is added to enhance the antifungal and antibacterial effects, the above compounds B and C can be obtained. After drying, each of these compounds A, B, and C becomes insoluble and stable, and their antifungal and antibacterial effects last for a long time.

Further, as a coating material having an antifungal and antibacterial effect to be used as a coating material, the following may be used. That is, alkylbenzenesulfonic acid is treated with one or more selected from the group consisting of trialkyltin hydroxide, 3,6-dichloropyridazine derivatives, and 3-chloro-6-methylpyridazine derivatives! It has an anti-fungal and anti-bacterial effect that is made by blending a reaction mixture obtained by heating and reacting with the - component! ? It may also be a 2f4 composition. In this case, the l-alkylbenzenesulfonic acid may be p-toluenesulfonic acid or dodecylbenzenesulfonic acid, and the di-trialkyltin may be tri-n-triisobutyltin.

It is also conceivable to use a coated shrine made by mixing oxidized steel or cuprous oxide, a pyridazine derivative, an arylsulfonic acid or its derivative, and a water-permeable resin in an alcohol solvent. In this case, the pyridazine derivative is a 3.6-dichloropyridazine lal-benne reaction product, the water-permeable resin is IDC (trade name), and the alcohol solvent is isobutyl alcohol. There are some things that can be considered.

By coating the entire surface of the sliding tube 1 with the anti-mold and anti-bacterial agent 13, the anti-mold and anti-bacterial action of the anti-mold and anti-bacterial agent 13 can prevent the proliferation of bacteria and the generation of mold.
The surface of the container can be maintained in a pristine condition, making it easier to handle during storage.

Next, other embodiments of the present invention will be described.

FIG. 2 shows an embodiment applied to a mouthpiece 21 used when inserting an endoscope through the oral cavity. In this embodiment, the entire surface of the mouthpiece 21 is coated with an antifungal and antibacterial agent 13.

Moreover, FIG. 3 shows an embodiment applied to an insertion aid 33 used when inserting a contrast medium injection tube 32 into a channel 31 of an endoscope. In this embodiment, the entire surface of the insertion aid 33 is The inner surface of the cylindrical body 34 is coated with an antifungal and antibacterial agent 13.

In addition, in Example 1-, the surface of the insertion aid was coated with the antifungal and antibacterial agent 13, but if the insertion aid is made of a polymer/material, the antifungal and antibacterial agent 13 may be mixed into the material. good. It goes without saying that the present invention is not limited to the embodiments described in -I-, but can also be applied to, for example, guide sheaths for flexible ureteroscopes.

[Effects of the Invention] As explained above, according to the present invention, the insertion aid is coated with an anti-fungal and anti-bacterial agent. 1-2 The anti-mold and anti-bacterial agent is in an insoluble and stable state that does not dissolve outside, so the anti-mold and anti-bacterial effect lasts for a long time. Assistive devices can be obtained.
