(First embodiment)
FIG. 1 is a perspective view showing an endoscopic drying confirmation tool according to the present embodiment, and FIG. 2 is a perspective view showing a state where an inflow port of the endoscopic drying confirmation tool in FIG. 1 is closed with a lid. FIGS. 3A and 3B are diagrams schematically showing a state in which the endoscope drying confirmation tool of FIG. 1 is connected to the endoscope end portion, with only the endoscope taken as a cross section, and FIG. 3 is an enlarged cross-sectional view of a portion surrounded by a one-dot chain line in FIG.

  As shown in FIG. 1, the endoscope drying confirmation tool 1 is an endoscope end part, for example, as shown in FIG. 3, a confirmation tool connected to the distal end of the insertion part 20 s of the endoscope 20. The gas A discharged from the channel opening 21k (see FIG. 4) of the channel 21 provided in the endoscope 20 when the side connection portion 2 and the confirmation tool side connection portion 2 are connected to the distal end of the insertion portion 20s. The main part is comprised including the ventilation | gas_flowing part 3 which has the gas inflow part 4 in which it flows in.

  The confirmation tool side connection portion 2 is formed in a ring shape from a stretchable member, for example, silicone rubber, and is fixed to the ventilation portion 3 by adhesion or the like. Moreover, the opening of the confirmation tool side connection part 2 comprises the inlet 2r of the gas A flowing into the gas inflow part 4 from the channel opening 21k, and the confirmation tool side connection part 2 is the insertion part of the inlet 2r. When connected to the tip of 20s, it is formed to have a diameter into which the tip of the insertion portion 20s fits. In addition, the diameter of the inflow port 2r is formed in a different size for each diameter of the insertion portion 20s.

  That is, the confirmation tool side connection part 2 covers the outer peripheral surface of the distal end of the insertion part 20s when the confirmation tool side connection part 2 is connected to the distal end of the insertion part 20s. As a result, the endoscope drying confirmation tool 1 is fixed to the distal end of the insertion portion 20s.

  As shown in FIG. 2, the inflow port 2r is shown in FIG. 2 when the endoscope drying confirmation tool 1 is not used, that is, when the confirmation tool side connection portion 2 and the distal end of the insertion portion 20s are not connected. The lid 7 closes the gas inflow portion 4 so as to be airtight.

  A position different from the inlet 2r in the gas inflow part 4 of the ventilation part 3, specifically, an end opposite to the end provided with the inlet 2r in the endoscope drying confirmation tool 1 is a wall part. An indicator 5 that is blocked by 3k and changes color by reacting with moisture contained in the gas is disposed on the wall 3k by being fixed with an adhesive or the like.

  The indicator 5 may be provided on the inner peripheral surface of the ventilation part 3 where the gas inflow part 4 is provided. Moreover, the indicator 5 is comprised from the material from which a color changes with humidity. Specifically, as the indicator 5, a material in which a material including cobalt chloride, a leuco dye, an acidic compound, and a deliquescent material is fixed to paper or the like is used.

  Further, when the endoscope drying confirmation tool 1 is not used, as described above, the inflow port 2r is blocked by the lid 7 so that the gas inflow portion 4 becomes airtight. Does not react with moisture contained in atmospheric gases.

  The ventilation part 3 is formed of a material having visible light transmission, for example, a transparent resin, so that the color of the indicator 5 arranged in the gas inflow part 4 from the outside of the ventilation part 3 can be observed.

  Further, as shown in FIG. 4, when the internal pressure of the gas inflow part 4 exceeds the set pressure with the inflow of the gas A to the gas inflow part 4, the gas A of the gas inflow part 4 is vented to the ventilation part 3. A valve body 9 such as a relief valve that discharges outside the portion 3 is provided.

  As shown in FIG. 3, the endoscope 20 to which the endoscope drying confirmation tool 1 is connected to the insertion portion 20s includes a channel 21 having one end communicating with the channel opening 21k. A channel opening 21m is also formed at the other end of the channel 21.

  Further, the device-side connecting portion 33 of the endoscope drying air supply device 100 is connected to the end portion of the endoscope 20 having the channel opening 21m. The endoscopic drying air supply device 100 includes an apparatus-side connecting portion 33, an air-supplying portion 31 that is connected to the device-side connecting portion 33 via an air-feeding conduit 34, and includes an air-feeding pump. The main part is comprised including the control part 32 which controls the air supply operation | movement of this air supply part 31. FIG.

  The air supply unit 31 supplies the gas A to the channel 21 of the endoscope 20 via the air supply line 34 and the apparatus side connection unit 33, and confirms the drying for the endoscope fixed to the distal end of the insertion unit 20s. It has a function of supplying the gas A to the gas inflow part 4 of the ventilation part 3 of the tool 1.

  In addition, the control unit 32 has a function of controlling the amount of gas A supplied from the air supply unit 31 for each endoscope information, for example, the diameter of the channel 21 of the endoscope 20. .

  Note that a filter that prevents the bacteria contained in the gas A from entering the channel 21 may be provided in the middle of the air supply pipe 34.

Next, the operation of the present embodiment will be described. ◎
After any of the cleaning, disinfection, sterilization, and rinsing of the endoscope 20, a known drying process is performed on the endoscope 20. As a result, although the outer surface of the endoscope 20 and the channel 21 are dried, the degree of drying of the outer surface can be visually confirmed, but the degree of drying of the channel 21 cannot be visually confirmed.

  Therefore, first, the operator fixes the endoscope drying confirmation tool 1 at the end of the endoscope 20 where the channel opening 21k is formed, for example, at the tip of the insertion portion 20s.

  Specifically, first, the operator removes the lid 7 blocking the inflow port 2r of the confirmation tool side connection part 2 of the endoscope drying confirmation tool 1, and inserts the confirmation tool side connection part 2 The tip of the part 20s is covered. As a result, the distal end of the insertion portion 20s is fitted into the inflow port 2r, and the endoscope drying confirmation tool 1 is fixed to the distal end of the insertion portion 20s.

  Next, the operator connects the device-side connection portion 33 to the end portion of the endoscope 20 where the channel opening 21m is formed, and then from the air supply portion 31 based on the air supply amount control of the control portion 32. Then, the gas A is supplied to the channel 21 of the endoscope 20 through the air supply pipe 34 and the apparatus side connection portion 33. Thereafter, the gas A flows into the gas inflow portion 4 of the endoscope drying confirmation tool 1 through the channel opening 21k and the inflow port 2r.

  In addition, since the valve body 9 is provided in the ventilation part 3, when the internal pressure of the gas inflow part 4 becomes equal to or higher than the set pressure, the gas A in the gas inflow part 4 does not exceed the set pressure. Since the internal pressure of the gas inflow portion 4 does not become equal to or higher than the set pressure because the air is exhausted to the outside of the ventilation portion 3 through the valve body 9, the endoscope drying confirmation tool 1 is removed from the distal end of the insertion portion 20s. It will not come off. When the valve body 9 is not provided, the controller 32 determines the amount of the gas A supplied from the air supply unit 31 so that the endoscope drying confirmation tool 1 does not come off from the distal end of the insertion unit 20s. If the amount is controlled, the same effect can be obtained.

  Thereafter, the operator confirms the degree of drying of the channel 21 by visually observing the indicator 5 disposed in the gas inflow portion 4 through the ventilation portion 3 formed of a transparent member.

  Specifically, on the other hand, when moisture still remains in the channel 21, as a result of the gas A flowing into the gas inflow portion 4, the water flows into the gas inflow portion 4 together with the gas A. The indicator 5 changes color. Therefore, when the worker visually recognizes the discoloration, the worker can easily recognize that the channel 21 is not sufficiently dried, and the drying process for the endoscope 20 is performed again.

  On the other hand, when moisture does not remain in the channel 21, even if the gas A flows into the gas inflow portion 4, the indicator 5 does not change color. It can be easily recognized that 21 is dry.

  Thus, in the present embodiment, the endoscope drying confirmation tool 1 is fixed to the end of the endoscope 20 where the channel opening 21k is formed, and the endoscope drying confirmation tool 1 The gas inflow section 4 is provided with an indicator 5 made of a material that changes color according to humidity. Furthermore, the gas inflow section 4 is connected to the end of the endoscope 20 where the channel opening 21m is formed via the channel 21. By supplying the gas A to the channel 21, the operator can easily recognize the discoloration associated with the gas A supplied from the indicator 5 through the ventilation part 3 formed of a transparent material, and easily The degree of drying can be confirmed.

  Further, in order to confirm the degree of drying of the channel 21, it is only necessary to prepare the endoscope drying confirmation tool 1 and the endoscope drying air supply device 100. Since it is not necessary to purchase a separate cleaning / disinfecting apparatus, the degree of drying of the channel 21 can be easily confirmed with less economic burden.

  From the above, it is possible to provide the endoscope drying confirmation tool 1 and the endoscope drying air supply device 100 having a configuration capable of easily confirming the drying in the channel 21 of the endoscope 20.

  Hereinafter, modifications will be described. In the present embodiment, as shown in FIG. 2, the inflow port 2 r is shown to be blocked by the lid body 7. However, the present invention is not limited to this, and the endoscope drying confirmation tool 1 is in the sealed container. Therefore, it is not always necessary to cover the inlet 2r with the lid 7. This is because even if the inlet 2r is opened, the indicator 5 does not react with moisture contained in the gas in the atmosphere due to the sealed container.

  Moreover, although the site | part on the opposite side to the inflow port 2r of the ventilation | gas_flowing part 3 was shown with the wall part 3k being shown, not only this but the drying confirmation tool 1 for endoscopes is sealed in an airtight container. In the case of being stored, holes may be formed in the wall 3k. This is because even if a hole is formed in the wall 3k, the indicator 5 does not react with moisture contained in the gas in the atmosphere due to the sealed container.

(Second Embodiment)

  Therefore, only these differences will be described, the same reference numerals are given to the same components as those in the first embodiment, and the description thereof will be omitted.

  As shown in FIG. 6, the ventilation portion 3 of the endoscope drying confirmation tool 40 in the present embodiment has a slit 8 communicating with the gas inflow portion 4 at a position between the inlet 2 r and the wall portion 3 k. As shown in FIG. 5 to FIG. 8, a sealing portion 10 that closes the gas inflow portion 4 can be inserted into and removed from the slit 8.

  The sealing part 10 includes an insertion part 11 that closes the gas inflow part 4 and a grip part 12 that is gripped by an operator, and a main part is configured. In addition, after inserting the sealing part 10 into the slit 8, as shown in FIG. 5 and FIG. 7, the insertion end of the insertion part 11 is fixed to the inner peripheral surface of the ventilation part 3 by adhesion or the like. Between the site | part 11 and the wall part 3k, it has the function which plugs the gas inflow part 4 as the sealed space 44. FIG.

  Therefore, the sealed space 44 (see FIG. 7) provided by the sealing unit 10 prevents the indicator 5 from reacting with moisture contained in atmospheric gas when the endoscope drying confirmation tool 40 is not used. 5 and 6, the inlet 2r is opened when the endoscope drying confirmation tool 40 is not used, but the inlet 2r is the lid shown in the first embodiment described above. It may be blocked by the body 7. Other configurations are the same as those of the first embodiment described above.

Next, the operation of the present embodiment will be described. ◎
When the endoscope 20 is subjected to a known drying process after cleaning, disinfection, sterilization, or rinsing with respect to the endoscope 20, and then confirming the drying of the channel 21, first, the operator An endoscopic drying confirmation tool 40 in which the sealing portion 10 is inserted and fixed to the slit 8 shown in FIG. 5 at the end of the endoscope 20 where the channel opening 21k is formed, for example, the tip of the insertion portion 20s. As shown in FIG. 7, it is fixed by the same method as in the first embodiment described above.

  At this time, since a part of the gas inflow portion 4 is closed as the sealed space 44 between the insertion portion 11 of the sealing portion 10 and the wall portion 3k, the indicator 5 is fixed to the wall portion 3k. Even if it comes off unexpectedly, the indicator 5 can be prevented from coming into contact with the insertion portion 20s of the endoscope 20.

  Next, as shown in FIGS. 6 and 8, the operator grips the grip portion 12 of the sealing portion 10 and pulls out the insertion portion 11 from the gas inflow portion 4 through the slit 8. As a result, the indicator 5 communicates with the channel 21 through the inlet 2r and the channel opening 21k.

  Thereafter, the operator connects the device-side connecting portion 33 to the end portion of the endoscope 20 where the channel opening 21m is formed, and then from the air supply portion 31 based on the air supply amount control of the control portion 32. Then, the gas A is supplied to the channel 21 of the endoscope 20 through the air supply pipe 34 and the apparatus side connection portion 33. As a result, the gas A flows into the gas inflow portion 4 of the endoscope drying confirmation tool 40 through the channel opening 21k and the inflow port 2r.

  Thereafter, the operator confirms the dry state of the channel 21 by visually recognizing the degree of discoloration of the indicator 5 through the ventilation portion 3. The confirmation operation is the same as that in the first embodiment described above, and a description thereof will be omitted.

  As described above, in the present embodiment, the ventilation portion 3 of the endoscope drying confirmation tool 40 has the slit 8 communicating with the gas inflow portion 4 at a position between the inflow port 2r and the wall portion 3k. In the slit 8, after the insertion, the sealing portion 10 that blocks the gas inflow portion 4 by the insertion portion 11 can be inserted and removed.

  According to this, the indicator 5 does not react with the moisture contained in the atmospheric gas when the endoscope drying confirmation tool 40 is not used due to the sealed space 44 formed by the insertion site 11. Therefore, it is possible to confirm the dry state of the channel 21 with certainty, and when the endoscope drying confirmation tool 40 is connected to the endoscope end, the fixing of the indicator 5 to the wall 3k is unexpectedly removed. In addition, the insertion portion 11 can prevent the indicator 5 from coming into contact with the end of the endoscope. Other effects are the same as those of the first embodiment described above.

  Hereinafter, modifications will be described. In the present embodiment, it has been shown that the endoscopic drying confirmation tools 1 and 40 are connected to the end of the endoscope, specifically, the distal end of the insertion portion 20s.
