る。2. Description of the Related Art In an endoscope, conduits such as a treatment instrument channel and an air / water supply channel are provided from the operation portion to the tip of an insertion portion. This conduit is easily contaminated with body fluid, blood, dirt, etc., and it is necessary to wash not only the outer surface of the endoscope but also the inside of the conduit after using the endoscope.

着した汚物を管壁から剥がして洗浄を行っている。However, since the pipe is thin and long, it is not possible to remove the dirt attached to the inner surface of the pipe simply by circulating the wash water. Therefore, conventionally, as shown in Japanese Utility Model Laid-Open No. 4-37402, a cleaning tool provided with a cleaning brush at the end of the wire is used, and the cleaning tool is inserted into the conduit of the endoscope and the cleaning brush is used. The pipe wall is rubbed to remove the attached dirt from the pipe wall for cleaning.

After that, an attempt has been made to inject a rinsing liquid into a pipe line to remove dirt.

(Alternatively, the endoscope is naturally left to dry the inside of the duct.) When it is necessary to sterilize the endoscope thereafter, for example, ethylene oxide gas sterilization (hereinafter, EO) is performed.
G sterilization) is performed.

Sterilization is usually performed in a step of drawing a negative pressure (almost vacuum) in the chamber, filling the chamber with ethylene oxide gas, and exposing the gas to the portion to be sterilized.

菌分を乾燥させることが、常識となっている。The purpose of making the inside of the chamber a negative pressure is to completely replace the inside of the chamber with a gas, but there is also the purpose of making a negative pressure to evaporate the water adhering to the object to be sterilized. If water is attached to the object to be sterilized, that portion does not come into contact with gas, so that sufficient sterilization cannot be performed. However, the negative pressure process is not universal. If the part to be sterilized seems to be too wet, it cannot be dried even in the negative pressure process. Therefore, in EOG sterilization, it is common knowledge that the sterilized component is sufficiently dried before the start of sterilization.

If the opening of the pipeline is wide, water droplets can be wiped off with a cotton swab or the like, but it cannot be wiped in the deep pipeline inside. Normally, we have no choice but to wait for it to dry naturally. In addition, JP-A-4-
Even if a sponge as shown in FIG. 13 of Japanese Patent No. 312437 gazette is used for wiping a duct, if the sponge's water content exceeds the permissible amount, the water absorption will be lost, and so there is no choice but to wait for natural drying.

In this embodiment, three continuous disk-shaped enlarging portions 4 in the axial direction are formed all around. It is provided in. The outer diameter d 1 of the enlarged portion is slightly larger than the inner diameter d 2 of the conduit of the endoscope. Furthermore, the cleaning aid 1 is attached to the proximal end of the flexible wire 2.
A grip portion 5 is provided for the operator to grip during the advancing / retreating operation.

Shows an endoscope 7 having a flexible insertion portion 6, and a channel conduit 9 is provided from the operation portion 8 to the insertion portion 6. The case of cleaning the channel conduit 9 will now be described. After cleaning the channel conduit 9 with an ordinary cleaning brush, rinsing water is injected from the channel opening 10 with a syringe or the like. Then, the cleaning aid 1 is inserted through the channel opening 10.

鏡７より排出される。FIG. 3 shows the water droplet scraping portion 3 at the tip of the cleaning aid 1 inserted into the channel conduit 9, and the enlarged portion 4 of the water droplet scraping portion 3 has a diameter larger than that of the channel conduit 9. Since it is large, it is elastically deformed and the pipe wall 1 of the channel pipe 9 is
While pressing 1, it is moved in the direction of the arrow. At that time, the water droplet a adhering to the tube wall 11 is scraped off. And
When the water droplet scraping unit 3 comes out of the tip end opening of the channel conduit 9, the water droplets accumulated in the channel conduit 9 are discharged from the endoscope 7.

Since the insertion resistance of the cleaning aid 1 also increases, the point is that the outer diameter of the water droplet scraping portion 3 should be determined by appropriately considering the hardness of the water droplet scraping portion 3 as an elastic body and the friction coefficient. It is necessary to determine the number of enormous parts 4.

The cleaning tool 13 is provided. The length of the flexible wire 2 between the cleaning brush 12 and the water droplet scraping portion 3 is determined from the channel conduit 9 extending from the tip forming portion 14 of the insertion portion 6 of the endoscope 7 to the channel opening portion 10. Is also long.

Fluorine resin such as PTFE, polyethylene, etc., especially any material may be used. Similarly, the balloon 18 may be made of a stretchable material such as silicone, latex, or polyolefin. A seal projection 19 is integrally provided on the outer peripheral surface of the balloon 18 and is continuous over the entire circumference. In this embodiment, the balloon 18 corresponds to the water droplet scraping unit 3 of the first embodiment. A rubber ball 20 having elasticity is provided at the base end of the cleaning aid 15, that is, the end of the tube member 16, and is bonded and fixed to the tube member 16.

The internal pressure increases and the balloon 18 is inflated through the tube member 16. Therefore, the balloon 18 is pressed against the tube wall 11 by the pressure. Then, the sealing projection 19 is attached to the pipe wall 1.
Press the entire circumference of 1 to scrape water droplets. Therefore, the diameter of the balloon 18 can be adjusted by the degree of force with which the rubber ball 20 is gripped, so that even if the inner diameter of the channel conduit 9 varies, one cleaning auxiliary tool 15 can be used.

Medical endoscopes and catheters must be properly disinfected or sterilized before use to prevent infection. As a pretreatment for disinfection and sterilization, it must be washed in water, but if the water remains attached to the endoscope, the disinfectant and sterilizer cannot touch the surface of the device. , Not sufficiently disinfected and sterilized. Therefore, it is necessary to remove all water after cleaning. In general, the outer surface of the device was completely wiped off with gauze, cloth, etc., but the water in the inner wall of the conduit for forceps or catheters built into the endoscope can be fed by a syringe or sucked. It was removed by suction with a container, or the water was evaporated in a drying furnace or the like for a very long time.

The water absorbing member 21 shown in FIG. 7 (a) has a substantially cylindrical shape and the outer diameter is the inner diameter of the pipe of an endoscope or the like. Is almost the same as or slightly larger than. The length is set to an appropriate size according to the shape and length of the conduit. As the material of the water absorbing member 21, a super absorbent polymer, cloth, paper or the like is suitable. In addition, the remaining moisture can be detected by using a paper or the like that changes color when absorbing water.
