Embodiments of the present invention will be described below with reference to the drawings. ◎
(First embodiment)
FIG. 1 is a diagram showing a state in which the endoscope cleaning evaluation tool showing the present embodiment is attached to the distal end portion of the insertion portion of the endoscope, and FIG. 2 is an endoscope cleaning evaluation tool of FIG. It is a perspective view which expands and shows.

  As shown in FIG. 1 and FIG. 2, the endoscope cleaning evaluation tool 1 includes a housing 1k, and the housing 1k is viewed at the end on one end side in the longitudinal direction N of the housing 1k. When connecting to the distal end portion 53 of the insertion portion 52 of the mirror 50, for example, a connection portion 1 s that covers the outer periphery of the distal end portion 53 is formed. The shape of the housing 1k can be appropriately determined according to the purpose, and examples thereof include a cylindrical shape and a columnar shape.

  A fluid circulation portion 2 that is a long hole along the longitudinal direction N is formed inside the housing 1k. When the housing 1k is connected to the distal end portion 53, the surface on the side where the connecting portion 1s in the longitudinal direction N of the housing 1k is formed is connected to the opening 55s of the channel 55 provided in the insertion portion 52. Thus, the first opening 2i of the fluid circulation part 2 that allows the liquid discharged from the opening 55s to flow into the fluid circulation part 2 is formed. That is, the first opening 2 i is formed at a position of the housing 1 k that can be connected to the opening 55 s when the housing 1 k is connected to the distal end portion 53.

  In addition, on the surface opposite to the side where the connection portion 1s is formed in the longitudinal direction N of the housing 1k, the liquid is introduced so that the liquid flowing into the fluid circulation portion 2 does not return to the channel 55 of the endoscope 50. A second opening 2t of the fluid circulation part 2 that discharges to the outside of the body 1k is formed.

  The fluid circulation part 2 communicates the first opening 2i and the second opening 2t, and the shape of the fluid circulation part is not particularly limited and can be appropriately determined according to the purpose. For example, in FIG. 1 and FIG. 2, a straight through structure having a linear shape along the longitudinal direction N is formed.

  Further, the diameter of the fluid circulation portion 2 is not particularly limited and can be appropriately determined according to the purpose. In FIG. 1, the liquid flow path diameter P1 is equal to the pipe diameter R1 of the channel 55 provided in the endoscope 50. They are formed to be the same (P1 = R1).

  Further, at least a part of the fluid circulation part 2 is configured with an indicator arrangement part 2h in which the channel diameter is formed larger than the channel diameter P1 of the other part. As shown in the enlarged view of FIG. 2, an indicator 3 having a flow path 3r having the same or substantially the same diameter as the flow path diameter P1 of the fluid circulation portion 2 is disposed inside.

  Indicator 3 is a coloring agent such as food red or ink; fluorescent paint; blood, a specific component in blood, a biological substance such as protein or mucin; a fluorescent modification of the biological component; Examples include substances that react to develop color, and these may be used in combination.

  Moreover, it is preferable that the indicator 3 is comprised from the substance with a high viscosity so that it may become difficult to detach | leave from the indicator arrangement | positioning part 2h, or it adheres to the indicator arrangement | positioning part 2h in a dry state.

  Moreover, you may adhere | attach the indicator 3 on the indicator arrangement | positioning part 2h using the material which has adhesiveness.

  Further, in order to make it difficult for the indicator 3 to be detached from the indicator placement portion 2h, the surface roughness of the adhesion surface of the indicator 3 of the indicator placement portion 2h may be formed to be rougher than the surface roughness of the fluid circulation portion 2.

  The casing 1k is preferably formed of a member that allows the indicator 3 arranged in the fluid circulation part 2 and the indicator arranging part 2h to be optically observed from outside the casing 1k. Specifically, from the member which can observe fluid circulation part 2, indicator arrangement part 2h, and indicator 3 by fluorescence or ultraviolet rays, the transparent member which fluid observation part 2, indicator arrangement part 2h, and indicator 3 can observe by visible light, etc. It is desirable that it be formed.

  The housing 1k is formed by, for example, joining two members.

  As shown in FIG. 1, the casing 1 k configured as described above is configured such that the inner peripheral surface of the connection portion 1 s is covered with the outer periphery of the distal end portion 53 of the insertion portion 52 of the endoscope 50. Connected. The endoscope cleaning evaluation tool 1 may be in close contact with the endoscope 50 through the connecting portion 1s, or may be in close contact with the endoscope 50 through a mounting member described later. When the connecting portion 1s is in close contact with the endoscope 50, it is preferable that the connecting portion 1s is rubbery or has a slip stopper disposed on the inner periphery.

  In order to improve the connection between the endoscope and the endoscope cleaning evaluation tool, a mounting member may be used in combination. For example, in FIG. 1, the outer peripheral surface of the connecting portion 1 s, for example, the mounting member 4 made of rubber is densely covered on the outer periphery of the distal end portion 53. As a result, the tip portion 53 can be tightly attached. This prevents the endoscope cleaning evaluation tool 1 from being detached from the distal end portion 53 after being mounted. As a result, as described above, the opening 55s of the channel 55 and the first opening 2i of the fluid circulation portion 2 are connected.

Next, the operation of the present embodiment will be described. ◎
First, as described above, after mounting the casing 1k of the endoscope cleaning evaluation tool 1 on the distal end portion 53, the channel 55 of the endoscope 50 is cleaned from the opening opposite to the opening 55s in the channel 55. Supply the liquid to be used. Examples of the liquid used for the cleaning include a cleaning liquid, a disinfecting liquid, and a rinsing liquid.

  The supplied cleaning liquid passes through the channel 55 and flows into the fluid circulation part 2 of the endoscope cleaning evaluation tool 1 through the opening 55s through the first opening 2i. Thereafter, the cleaning liquid passes through the fluid circulation part 2 and is discharged out of the endoscope cleaning evaluation tool 1 from the second opening 2t. As a result, the channel 55 and the fluid circulation part 2 are cleaned with the cleaning liquid.

  At this time, with the passage of the cleaning liquid in the fluid circulation part 2, the indicator 3 arranged in the indicator arranging part 2h is gradually detached from the indicator arranging part 2h. The method for observing the separation of the indicator 3 can be appropriately selected depending on the material of the housing or the material of the indicator.

  For example, when the casing is formed of a transparent member, it can be visually observed through the casing. For example, when the indicator includes a fluorescent substance, it can be observed by observing whether the indicator placement portion emits light by irradiating electromagnetic waves. For example, when ink is used as the indicator, observation can be performed by observing the color of the cleaning liquid discharged from the second opening as illustrated in FIG.

The detachment condition of the indicator 3 may be stricter than the detachment condition of the dirt attached to the actual endoscope. In this case, the condition for confirming the cleaning of the endoscope can be strict, Certainty can be increased.
Finally, after confirming the cleaning properties of the channel 55, the supply of the cleaning liquid to the channel 55 is stopped.

  Thus, in the present embodiment, it is possible to confirm the cleanability of the channel 55 on time.

  In addition, by preparing a plurality of endoscope cleaning evaluation tools 1 having different flow path diameters P1 of the fluid circulation part 2, this embodiment can be applied to a plurality of types of endoscopes having different channel diameters R1 of the channels 55. Can be applied.

  In the present embodiment, it has been shown that the cleaning evaluation of the channel 55 using only the cleaning liquid is performed using the endoscope cleaning evaluation tool 1. However, the present invention is not limited to this, and the cleaning brush is connected to the channel together with the cleaning liquid. The endoscope cleaning evaluation tool 1 may be used for the cleaning evaluation in the case where the scrubbing is performed after being inserted into the fluid flow unit 2 and the fluid circulation portion 2.

  Specifically, when the observer inserts a cleaning brush into the channel 55 from the opening opposite to the front end opening 55 s in the channel 55 and scrubs the channel 55 and the fluid circulation part 2, the observer is transparent. By brushing through the housing 1k, it was confirmed that at least a part of the indicator 3 was detached from the indicator placement portion 2h by brushing, so that the inside of the channel 55 could be brushed and cleaned more than specified in the instruction manual. Can be easily confirmed. That is, the observer can easily check the brushing degree in the channel 55 from the indicator 3.

  Further, in the present embodiment, the connecting portion 1s of the housing 1k and the mounting member 4 are in close contact with the distal end surface and a part of the outer peripheral surface of the distal end portion 53 of the insertion portion 52 of the endoscope 50. Even if the endoscope 50 is immersed in a cleaning solution together with the endoscope cleaning evaluation tool 1, the contacted portion cannot be cleaned. However, the outer surface of the endoscope is usually cleaned with gauze or the like before the channel is cleaned. In addition to wiping and cleaning, the endoscope cleaning evaluation tool 1 is removed from the distal end portion 53 after being cleaned, and then wiped and cleaned by gauze or the like. The close contact portion can also be reliably washed.

  A modification will be described below with reference to FIGS. 3 is a view showing a modification of the shape of the fluid circulation portion formed in the casing of the endoscope cleaning evaluation tool of FIG. 1, and FIG. 4 is formed in the casing of the endoscope cleaning evaluation tool of FIG. It is a figure which shows the modification of the shape different from FIG. 3 of the made fluid distribution | circulation part.

  In the present embodiment described above, as shown in FIGS. 1 and 2, the fluid circulation part 2 is shown to have a straight structure having a linear shape along the longitudinal direction N.

  Not only this but as shown in FIG. 3, the fluid distribution | circulation part 2 may have a crank structure which has the crank part 2a, and as shown in FIG. 4, the spiral which has the spiral part 2r It may be formed with a structure.

  According to the fluid circulation part 2 having the shape shown in FIG. 3 and FIG. 4, the cleaning liquid is less likely to pass through the fluid circulation part 2 than the linear fluid circulation part 2 described above. It is difficult for the indicator 3 to be detached from the portion 2h.

  Further, the endoscope cleaning evaluation tool 1 including the fluid circulation part 2 having the crank shape and the spiral shape shown in FIGS. 3 and 4 is used for, for example, a channel of a colonoscope or the like which is easily contaminated with a channel. Used for cleaning evaluation, the endoscope cleaning evaluation tool 1 including the fluid circulation part 2 having the linear shape shown in the present embodiment is used for cleaning evaluation of an endoscope channel where dirt is hardly attached, etc. Depending on the application, different cleaning evaluation tools may be used.

  Hereinafter, another modification will be described with reference to FIG. FIG. 5 is a diagram illustrating a state in which an endoscope cleaning evaluation tool in which the same number of fluid circulation portions as the number of channels included in the endoscope are formed is attached to the distal end portion of the insertion portion of the endoscope. is there.

  As shown in FIG. 5, in the case where another channel 56 is provided in addition to the channel 55 in the insertion portion 52 of the endoscope 50, the endoscope cleaning evaluation tool 1 attached to the distal end portion 53 is provided. In the housing 1k, one having two fluid circulation portions is used.

  Specifically, when the endoscope cleaning evaluation tool 1 is attached to the distal end portion 53 of the housing 1k, the first opening 2i is connected to the distal end opening 55s of the channel 55, so that the channel 55 The above-described fluid circulation portion 2 that is in communication is formed, and the first opening 6 i that is opened on the surface where the first opening 2 i is opened is connected to the tip opening 56 s of the channel 56, whereby the channel A fluid circulation portion 6 that communicates with 56 is formed.

  The first opening 6i is opened at a position connected to the distal end opening 56s when the endoscope cleaning evaluation tool 1 is attached to the distal end 53 in the housing 1k. In this configuration also, the housing 1k is preferably formed from a transparent member.

  Further, the second opening 6t opposite to the first opening 6i in the fluid circulation portion 6 is on a surface different from the surface in which the second opening 2t is formed in the housing 1k, for example, the side surface of the housing 1k. It is open. This is because each of the second openings 2t and 6t is formed at a different position so that the cleaning liquid discharged from each of the second openings 2t and 6t is discharged from which second opening. This is because it becomes easier to see. Therefore, if this is ignored, the second opening 6t may also be opened on the same surface as the second opening 2t.

  The fluid circulation part 6 is formed so that the flow path diameter P2 is the same as the pipe diameter R2 of the channel 56 (P2 = R2).

  Furthermore, the fluid circulation part 6 may also be formed to have a straight through structure having a linear shape as shown in FIG. 5, as in the fluid circulation part 2 described above. As shown in FIG. It may be formed with a crank structure having a portion, or may be formed with a spiral structure having a spiral portion as shown in FIG.

  Further, in the present embodiment, an example is shown in which one indicator 3 is provided in the indicator placement portion 2h of the fluid circulation portion 2, but as shown in FIG. 5, the indicator placement portion in the fluid circulation portion 2 is provided. May be arranged at different positions, and the indicators 3a to 3c having the same configuration as the indicator 3 may be arranged in each indicator arrangement unit, that is, three indicators are arranged in the fluid circulation unit 2. It doesn't matter.

  Furthermore, two indicator placement portions may be provided in the fluid circulation portion 6 at different positions, and indicators 7a and 7b having the same configuration as the indicator 3 may be placed in each indicator placement portion. Two indicators may be arranged in the distribution unit 6.

  Of course, three indicators may be provided in the fluid circulation part 6, or two indicators may be provided in the fluid circulation part 2. Furthermore, each of the fluid circulation units 2 and 6 may be provided with four or more indicators.

  According to such a configuration, even if two channels having the same pipe diameter or different pipe diameters are provided in the insertion portion 52 of the endoscope 50, each endoscope cleaning evaluation tool The channel cleaning evaluation can be performed in the same manner as the above-described embodiment.

  The above is the same when three or more channels are provided in the insertion portion, and the same number of fluid circulation portions communicating with each channel are provided in the endoscope cleaning evaluation tool 1. In addition, if an indicator is provided in each fluid circulation part, the cleaning evaluation of each channel can be performed in the same manner.

  Hereinafter, a modification will be described with reference to FIG. FIG. 6 is a view showing a modified example in which a cylindrical body having a fluid circulation part provided with an indicator is detachable from the endoscope cleaning evaluation tool.

  As shown in FIG. 6, the fluid circulation part 2 having the indicators 3 a to 3 c is detachable from the endoscope cleaning evaluation tool 1 by the cylindrical member 31, and the fluid circulation part 6 having the indicators 7 a and 7 b is provided. The cylindrical member 32 may be detachable from the endoscope cleaning evaluation tool 1.

  According to such a configuration, after the cleaning of the channels 55 and 56 is completed, the cylindrical members 31 and 32 are removed from the endoscope cleaning evaluation tool 1 and the cylindrical members 31 and 32 are placed in the reagent E, whereby the observer Can evaluate the detergency of the channel 55 by observing the protein reaction or peroxidase reaction from the reagent E in which the indicator is dissolved, or measuring the amount of residual protein. Thus, it goes without saying that the cleaning evaluation may be performed using the cylindrical members 31 and 32.

  Hereinafter, another modification will be described with reference to FIG. FIG. 7 is a diagram illustrating a configuration of a modified example in which the indicator is removable from the endoscope cleaning evaluation tool.

  As shown in FIG. 7, the indicators 3 a to 3 c may be detachable from each indicator placement portion of the endoscope cleaning evaluation tool 1. According to this, each of the indicators 3a to 3c is introduced into the reagent E in the same manner as in FIG. 6 described above, so that the fluid flows along the longitudinal direction N from the color change state of each reagent E in which the indicator is dissolved. It can be confirmed whether the portion 2 is uniformly cleaned, that is, whether the channel 55 is uniformly cleaned along the longitudinal direction N.

  This is because, for example, when the degree of color change of the indicator 3a is small and the degree of color change increases as the indicator 3b and the indicator 3c become, it can be determined that a cleaning failure has occurred due to the site in the longitudinal direction N.

  In addition, the indicators 3a-3c have the component which assumed the stain | pollution | contamination adhering to the used endoscope. For example, it has a protein component, specifically, a component related to blood, bone, skin, tendon, or other organ / tissue.

  More specifically, blood, serum, fibrin-removed blood, blood with anticoagulant, gelatin, collagen, mucin, egg, egg white, albimine, lecithin, semolina pudding, oatmeal, potato flakes, etc. Alternatively, a liquid material diluted by adding water or the like as necessary may be used. These various soil components can be used alone or in admixture of two or more. Further, dirt posted in various countries such as international standards (ISO15883-5) may be used.

  That is, the dirt to be attached varies depending on the site where the endoscope is used, so that the dirt component used for the indicators 3a to 3c may be changed according to the site to be used.

  For example, after using an endoscope for the digestive tract system, for example, mucin, albumin, and lecithin are attached to the indicators 3a to 3c, and the cleaning evaluation is performed using the endoscope cleaning evaluation tool 1 more reliably. Cleaning evaluation can be performed.

  For example, after using an endoscope for the respiratory system, for example, serum, fibrin-removed blood, or anticoagulant-added blood is attached to the indicators 3a to 3c, and cleaning evaluation is performed by the endoscope. If the cleaning evaluation tool 1 is used, the cleaning evaluation can be performed more reliably.

(Second Embodiment)
FIG. 8 is a diagram illustrating the endoscope cleaning evaluation tool, the light measurement device, and the cleaning device according to the present embodiment, together with the distal end portion of the insertion portion of the endoscope.

  Compared with the configuration of the first embodiment shown in FIGS. 1 to 5 described above, the configuration of the second embodiment uses an endoscope cleaning evaluation tool, and uses an optical measurement device and a cleaning device. The difference is that the channel is automatically evaluated for cleaning rather than the operator's visual recognition.

  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. 8, in the present embodiment, after the endoscope cleaning evaluation tool 1 is attached to the distal end portion 53 of the insertion portion 52 of the endoscope 50, A light source 11 such as an LED and a detector 12 are arranged. The light source 11 and the detector 12 are arranged to face each other so as to sandwich the endoscope cleaning evaluation tool 1. The casing 1k of the endoscope cleaning evaluation tool 1 is formed of a member that transmits light, for example, visible light, such as a transparent member.

  The light source 11 is a device that emits light toward the detector 12 and enters the indicators 3a to 3c arranged in the indicator arrangement portion of the endoscope cleaning evaluation tool 1 through the housing 1k. .

  The detector 12 measures the light transmissivity or light reflectivity of each indicator 3a-3c of the indicator arrangement part in the endoscope cleaning evaluation tool 1 from the amount of light.

  The light source 11 and the detector 12 are connected to the determination unit 13. The determination unit 13 determines the cleaning property of the fluid circulation unit 2, that is, the channel 55 from the light amount measured by the detector 12. A specific determination method by the determination unit 13 will be described later.

  The determination unit 13 is connected to the main substrate 14, and the main substrate 14 is connected to the detector 12 and the water supply device 15 of the cleaning device 20.

  In addition, the light source 11, the detector 12, the determination unit 13, and the main board 14 constitute the light measurement device 10. The light source 11, the detector 12, the determination unit 13, the main substrate 14, and the water supply device 15 may be provided in the cleaning device 20.

  Next, the effect | action of this Embodiment is demonstrated using FIG. 8, FIG. 9, FIG.

  FIG. 9 is a chart showing the criteria by which the determination unit evaluates the cleaning performance of the channel from the relationship between the amount of transmitted light detected by the detector of FIG. 8 and time, and FIG. 10 is the channel performed by the determination unit of FIG. It is a flowchart which shows the cleaning property evaluation. In the following description, it is assumed that the detector 12 measures the amount of light transmitted.

  After the endoscope cleaning evaluation tool 1 is attached to the distal end portion 53 of the endoscope 50 and the cleaning liquid is supplied to the channel 55 and the fluid circulation portion 2, as shown in FIG. In step S <b> 1, it is determined whether the signal of the detector 12 is detected via the main board 14. If the signal from the detector 12 is detected, the process proceeds to step S2, and if not detected, the process jumps to step S5.

  In step S <b> 2, the determination unit 13 performs light emission start control on the light source 11 and performs light reception start control of light transmitted through the indicator 3 on the detector 12, that is, light amount measurement control.

  Thereafter, in step S3, the determination unit 13 determines by constantly monitoring whether the light transmission amount measured by the detector 12 is equal to or greater than the threshold value W illustrated in FIG. As shown in FIG. 9, the amount of transmitted light increases from the time when it starts to be detached from the indicator 3, and after the indicator 3 is detached, it shows a certain amount.

  If it is less than or equal to the threshold value W, the process branches to step S4, and the determination unit 13 instructs the water supply device 15 to continue cleaning, and repeats the determination in step S3 until the value exceeds the threshold value W. That is, the cleaning of the channel 55 is continued by controlling the water supply device 15. If it is equal to or greater than the threshold value W, the determination unit 13 determines that at least a part of the indicator 3 has been detached from the indicator placement unit of the fluid circulation unit 2, that is, the fluid circulation unit 2 and the channel 55 have been washed, and the step The process proceeds to S5.

  Further, instead of instructing to continue cleaning in step S4, an instruction may be issued to start cleaning with a new program.

  In step S <b> 5, the determination unit 13 performs light emission stop control on the light source 11 and performs light reception stop control on the detector 12. Finally, in step S <b> 6, the determination unit 13 performs control to stop liquid feeding from the water feeding device 15.

  As described above, in the present embodiment, the cleaning property of the channel 55 is automatically measured using the light source 11, the detector 12, the determination unit 13, and the main substrate 14.

  According to this, even if the operator does not visually recognize the endoscope cleaning evaluation tool 1, the light measurement device 10 automatically confirms the cleaning performance of the channel 55 from the endoscope cleaning evaluation tool 1. Therefore, the detergency evaluation of the channel 55 can be easily performed.

  Moreover, since light sources such as LEDs are very inexpensive, the cleaning performance of the channel 55 can be evaluated at a low cost. Other effects are the same as those of the first embodiment described above.

  In the present embodiment, it has been shown that the optical measurement device 10 automatically determines the cleaning property of the channel 55 via the endoscope cleaning evaluation tool 1 during the cleaning of the channel 55. Not limited to this, after all of the cleaning process and the disinfection process for the endoscope 50 are completed, the optical measuring device 10 is used to determine the cleaning property of the channel 55 as described above, and the cleaning and disinfection are performed according to the determination result. Of course, the process may be performed again.

  Further, if the light measurement device 10 itself has a fluid circulation portion, the light measurement device 10 itself is connected to the distal end portion 53 of the insertion portion 52 of the endoscope 50 without using the endoscope cleaning evaluation tool 1. It goes without saying that the detergency of the channel 55 may be determined from an indicator installed in the fluid circulation portion of the light measurement device 10.

  Also in the present embodiment, as shown in FIG. 7, it is needless to say that the dirt component attached to the indicator may be changed according to the member used for the endoscope.

  Furthermore, the present embodiment is also applicable when the insertion portion 52 of the endoscope 50 has a plurality of channels as shown in FIG. 5 described above.

  In the first and second embodiments described above, the case where the endoscope cleaning evaluation tool 1 is attached to the distal end portion of the insertion portion of the direct-view type endoscope is shown as an example. Of course, the present invention can also be applied to the case where it is attached to the distal end portion of the insertion portion of the side-view type endoscope.
