Description

  The present invention relates to a storage bag for storing an electronic endoscope and a storage method for an electronic endoscope during a period from pre-cleaning to reprocessing.

  Conventionally, in the medical field, examinations using electronic endoscopes have been actively performed. The electronic endoscope has an insertion portion that is inserted into the body cavity of the subject and a distal end portion that is provided continuously from the insertion portion. A solid-state imaging device such as a CCD and an illumination unit that illuminates the inside of a body cavity are built in the distal end portion. The imaging signal output from the CCD is subjected to various signal processing by the processor device, and is displayed on the monitor as an image in the body cavity.

  The electronic endoscope used in the inspection is pre-cleaned by the operator at the bedside, and then is fully refurbished in the cleaning tank of a dedicated cleaning / disinfecting device, such as cleaning, disinfection, rinsing, and drying. Processed, cleaned and sterilized.

  In pre-cleaning, the outer surface of the electronic endoscope is wiped off with a gauze or cloth, and body fluids and dirt that have entered the forceps channel (suction channel) and the air / water nozzle are washed away with a detergent. Easy cleaning for processing, but the forceps channel and air / water supply nozzle are relatively small in diameter and have a complicated structure, so it takes time to clean, and all parts are sure There was a problem of being suspicious or washed. In addition, if there is a time between pre-cleaning and reprocessing, body fluids and filth are fixed and difficult to remove, and there is a possibility that they remain unwashed.

  In order to solve the above problem, a cleaning liquid containing a moisturizing material and a degrading enzyme is sealed in a tank pressurized with nitrogen gas, and the cleaning liquid is discharged to the outside with a nozzle having a straight tube shape. There has been proposed a cleaning device for medical instruments (see Patent Document 1).

  The electronic endoscope after the reprocessing process is stored in a predetermined storage location as it is. For this reason, even if disinfection and sterilization is performed in the corner reprocessing process, there is a possibility that the electronic endoscope is exposed to the surrounding environment and contaminated between the storage and use of the electronic endoscope. Therefore, in order to maintain a sterilized state after the reprocessing process, a package that encloses an electronic endoscope has been proposed (see Patent Document 2).

By the way, for hospitals and medical checkup centers that conduct examinations of electronic endoscopes, it is necessary to provide a complete system of electronic endoscopes and processor units, or a complete cleaning and disinfecting device in terms of securing cost and installation space. It is a considerable burden. In particular, the reprocessing process is a problem that is unrelated to medical practice and is a troublesome and time-consuming work that does not generate profits. In order to solve this problem, we rented electronic endoscopes that meet the requests from hospitals and medical checkup centers, collected used electronic endoscopes at the rental center after inspection, and collected them at the rental center. Thus, a medical equipment rental system that performs reprocessing is proposed (see Patent Document 3).

  When considering a medical equipment rental system as described in Patent Document 3, a certain amount of time is expected between the time when pre-cleaning is performed after completion of the inspection and the time when reprocessing is performed at the rental center. There must be. For this reason, as described above, it is necessary to take some measures to prevent the outer surface of the electronic endoscope from being dried and bodily fluids and dirt from being fixed and difficult to remove.

  However, it is better to keep the dry state only at the tip portion where the CCD or the like is arranged. This is because if the tip is placed in a humid environment for a long time, moisture will enter the inside and condensation will occur on the cover glass that protects the CCD, resulting in markedly degraded image quality, making observation difficult, and wiring with moisture. This is because there is a concern that a problem may occur due to short-circuiting.

  Patent Document 1 is intended to prevent drying of thin tubes such as forceps channels, and does not prevent drying of the entire outer surface of an electronic endoscope. The sterilization package of Patent Document 2 is used after reprocessing, and is not used between pre-cleaning and reprocessing. In the first place, Patent Document 3 does not describe a measure for preserving the electronic endoscope between the pre-cleaning and the reprocessing process, and the outer surface of the electronic endoscope is dried, so that it is difficult to remove body fluid and dirt. Does not consider the problem.

  As a measure for preventing the drying of the outer surface of the electronic endoscope, the cleaning device disclosed in Patent Document 1 sprays a moisturizing material on the entire outer surface of the electronic endoscope excluding the tip, and then described in Patent Document 2. Although it is conceivable to enclose in a package, the spraying of the moisturizing material has poor workability and may cause uneven spraying.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to keep the tip portion in a dry state while reliably preventing the outer surface of the electronic endoscope other than the tip portion from being dried. .

  In order to achieve the above object, the invention according to claim 1 is a storage bag in which an electronic endoscope is accommodated during a period from pre-washing to reprocessing. A possible opening, an insertion part of the electronic endoscope to be inserted into the subject are accommodated, a first accommodation part filled with a moisturizing liquid, and a continuous connection from the insertion part to image the inside of the subject And a second storage portion for storing the distal end portion of the electronic endoscope having a built-in imaging unit for preventing the moisturizing liquid from flowing into the second storage portion, and And a seal portion that allows insertion of the tip portion.

  In addition, “pre-cleaning” is a cleaning operation that is simply performed at the bedside by the operator after the examination by the electronic endoscope, and mainly wipes the outer surface of the electronic endoscope with gauze or cloth, This means washing away body fluids and dirt that have entered the forceps channel (suction channel) and air / water nozzle with detergent. “Reprocessing” refers to a full-fledged cleaning / disinfecting process for the purpose of disinfecting and sterilizing electronic endoscopes, and is a process that involves cleaning, disinfecting, rinsing, and drying using a dedicated cleaning / disinfecting device. is there.

  It is preferable to include a storage unit that stores unique information of the storage bag itself. In this case, the storage means is preferably an RFID tag.

  The invention according to claim 5 is a method for storing and storing an electronic endoscope in a storage bag between pre-washing and reprocessing, which is inserted into a subject. The insertion part of the electronic endoscope to be stored is housed in the first storage part of the storage bag filled with a moisturizing liquid, and an imaging part connected to the insertion part for imaging the inside of the subject is built in The distal end portion of the electronic endoscope is stored in a second storage portion of the storage bag in which inflow of the moisturizing liquid is prevented or restricted.

  It is preferable to use the storage bag that has a seal portion that prevents the inflow of the moisturizing liquid and allows the tip portion to be inserted, and the first and second storage portions are formed by the seal portion. .

  Alternatively, as the storage bag, a length from the upper end to the lower end is approximately the same as the insertion portion, the insertion portion is stored in the storage bag with the distal end portion being the lower end side, and the moisturizing liquid The storage bag is sealed by injecting the moisturizing liquid until the distance between the liquid level and the upper end is the same as the distance from the lower end to the tip, and the electronic endoscope is turned upside down with the storage bag. Preferably, the first and second storage portions are formed by suspending and moving the air in the space between the liquid level and the upper end to the lower end side.

  Alternatively, as the storage bag, a length from the upper end to the lower end is approximately the same as that of the insertion portion, and the insertion portion is stored in the storage bag with the distal end portion on the lower end side, than the upper end. The first and second storage parts are formed by bending the insertion part together with the storage bag in a U-shape so that the tip part is slightly higher and suspending it, and providing a space at the lower end. It is preferable.

  In this case, the storage bag preferably has an opening that can be opened and closed at the lower end, and the space is provided by opening the opening and opening the lower end to the atmosphere. Then, the insertion part is bent and suspended in a U shape, and after the opening is opened, the moisturizing liquid is injected until the liquid surface of the moisturizing liquid is in front of the upper end and the tip part. . Alternatively, after injecting the moisturizing liquid until the distance between the liquid surface of the moisturizing liquid and the upper end is approximately the same as the distance from the lower end to the tip, the insertion portion is bent into a U shape. The opening is opened while hanging.

  An inlet / outlet is provided in the operating portion connected to the distal end portion and the proximal end of the insertion portion, and air is provided to the lower end via a communication channel of the electronic endoscope that communicates from the distal end portion to the operating portion. It is preferable to provide the space by sending

  According to the electronic endoscope storage bag and the electronic endoscope storage method of the present invention, the insertion portion other than the distal end portion of the electronic endoscope is stored in the first storage portion filled with the moisturizing liquid, Since the tip portion is stored in the second storage portion where the inflow of the moisturizing liquid is blocked by the seal portion, the tip portion can be kept dry while reliably preventing the outer surface other than the tip portion from being dried. Therefore, the outer surface of the electronic endoscope is dried, and it is difficult for body fluid and dirt to adhere to it, and it is difficult to remove the body fluid and dirt during reprocessing, and the tip is placed in a humid environment. It is possible to prevent various problems that occur when

Poured. And the opening 61 is closed and the 1st accommodating part 62 is sealed. The storage bag 60 is returned to the original return bag 30 together with the electronic endoscope 10. The processes from S12 to S15 are repeated until all the inspections are completed (No in S16).

  When all inspections are completed (Yes in S16), the service person of the rental contractor 12 operates the operation unit 26 when collecting the electronic endoscope 10 from the inspection laboratory 11 to the cleaning factory 13 in S17. Thus, when the RFID tag reader 29 is activated, the unique information stored in the RFID tag 70 is read by the RFID tag reader 29 as shown in S18. Then, as shown in S19, whether or not the storage state of the electronic endoscope 10 is appropriate is determined by determining whether or not the unique information has been read by all the RFID tag readers 29 in the arithmetic processing circuit 28. .

  If it is determined that the storage state of the electronic endoscope 10 is inappropriate (yes in S20), a warning message is displayed on the display unit 25 as shown in S21. In this case, a person in charge at the inspection laboratory 11 or a service person puts the electronic endoscope 10 whose storage state is determined to be inappropriate into the storage bag 60 and injects the moisturizing liquid 65.

  If it is determined that the storage state of the electronic endoscope 10 is appropriate (no in S20), the rack 20 is loaded back onto the truck 14 as shown in S22, and the inspection is performed on the truck 14 as shown in S52. It is collected from the place 11 to the washing factory 13.

  After the collection, at the washing factory 13, the used electronic endoscope 10 is taken out from the return bag 30 and the storage bag 60, and as shown in S53, the electronic endoscope 10 is reprocessed. . The return bag 30 and the storage bag 60 are discarded. Further, as shown in S34, the rental contractor 12 charges a fee to the inspection laboratory 11, and as shown in S23, the rental contractor 12 pays the fee to the rental contractor 12.

  As described above, the storage bag 60 for storing the electronic endoscope 10 after pre-cleaning, the insertion portion 40 other than the distal end portion 44 and a part of the operation portion 41 to the first storage portion 62, and the distal end portion 44 to Since it is configured to be stored in the second storage portion 63, the outer surface of the electronic endoscope 10 after the pre-cleaning and before it is collected by the truck 14 at the cleaning factory 13 and reprocessed. It is possible to prevent the bodily fluids and dirt attached to the outer surface from becoming difficult to fall off. In particular, in the case of the endoscope rental system 2, the time between the pre-cleaning and the reprocessing process is time consuming, and thus the problem that body fluid and filth are fixed by drying is a problem to be solved with the highest priority. Can be solved by applying. If such measures are taken, there will be no unwashing in the reprocessing process, and the patient's sense of security will be further increased.

  Further, it is possible to prevent problems such as dew condensation on the cover glass that protects the CCD, which significantly deteriorates the image quality and makes observation difficult, or the wiring is short-circuited due to moisture. In addition, the impact applied to the electronic endoscope 10 during transportation can be absorbed by the moisturizing liquid 65.

  An RFID tag 70 for storing the unique information is provided in the storage bag 60, the unique information is read by the RFID tag reader 29 of the rack 20, and the suitability of the storage state of the electronic endoscope 10 is determined based on the read result. In such a case, a warning is displayed, so that an appropriate storage state can always be secured.

  In the above-described embodiment, an example in which a warning message is displayed on the display unit 25 when the storage state of the electronic endoscope 10 is inappropriate is given. You may display that 10 preservation | save states are unsuitable.

  The person who operates the RFID tag reader 29 and determines whether or not the storage state of the electronic endoscope 10 is appropriate is not limited to the service person of the above-described embodiment, but may be a person of the laboratory 11. In short, it is only necessary to confirm whether or not the electronic endoscope 10 is correctly stored in the storage bag 60 before the electronic endoscope 10 is collected.

  The following example can be considered as another utilization method of the RFID tag 70. That is, an RFID tag storing unique information (model number, serial number, application, number of uses (cleaning, disinfection), etc.) is also attached to the electronic endoscope 10. The attachment location of the RFID tag may be, for example, a joint between the operation unit 41 and the insertion unit 40. Then, the unique information of each of the electronic endoscope 10 and the storage bag 60 is read by the RFID tag reader 29, and the corresponding relationship between the electronic endoscope 10 and the storage bag 60 (which electronic endoscope 10 is stored in which storage bag 60). Remembered). When the RFID tag reader 29 reads the RFID tags of the electronic endoscope 10 and the storage bag 60, an anti-collision function is used to avoid interference between the two.

  In this case, if the actual inspection contents are managed for each electronic endoscope 10, the actual inspection contents and the storage are stored by collating with the correspondence relationship between the electronic endoscope 10 and the storage bag 60 stored in advance. The correspondence with the bag 60 can be known. The storage bag 60 corresponds to so-called medical waste, and when the storage bag 60 is discarded, it is necessary to select an appropriate disposal method according to the inspection content. However, there is a correspondence between the inspection content and the storage bag 60. If it is known, it can be surely disposed by an appropriate disposal method, and secondary infection and biohazard can be prevented. In addition, an RFID tag reader is also provided in the cleaning / disinfecting apparatus of the cleaning factory 13, and the electronic endoscope 10 was stored in the designated storage bag 60 based on the correspondence between the electronic endoscope 10 and the storage bag 60. It is also possible to take a measure such as displaying a warning or changing the cleaning program (for example, lengthening the cleaning time, etc.).

  As means for storing and reading unique information, other means such as a barcode and a barcode reader may be used in place of the RFID tag 70 and the RFID tag reader 29 of the above embodiment. Further, the return bag 30 and the storage bag 60 may be configured to be reusable by autoclave sterilization instead of the disposable example illustrated in the above embodiment.

  The storage bag can be variously modified regardless of the aspect exemplified in the above embodiment. For example, an opening / closing mechanism 81 such as a zipper may be provided on one side surface of the first storage portion 62 as in the storage bag 80 shown in FIG. Thus, if one side surface of the first storage portion 62 is opened, the front end portion 44 is directly inserted into the pressure inlet 67 and the front end portion 44 is stored in the second storage portion 63, and then the opening 61 and the opening / closing Since the mechanism 81 only needs to be closed, the electronic endoscope 10 can be stored more easily than in the above-described embodiment in which the distal end portion 44 is inserted from the opening 61.

  In addition, the first storage portion 62 and the second storage portion 63 do not necessarily have to be partitioned by the seal portion 64 as long as the tip portion 44 can be maintained in a state where it is not constantly immersed in the moisturizing liquid 65. When the storage bag 90 shown in FIG. 9 in which only the opening 61 is provided and there is no seal portion 64 and therefore there is no distinction between the first storage portion 62 and the second storage portion 63, the tip end portion 44 is the moisturizing liquid 65. Examples of the method for avoiding soaking are shown in FIGS. 10 to 12.

  In the example shown in FIG. 10, as shown on the upper side of the arrow, after the electronic endoscope 10 is stored in the storage bag 90 with the distal end portion 44 set to the lower end side (the end opposite to the opening 61), the moisture retention is performed. The moisturizing liquid 65 is injected until the distance between the liquid level of the liquid 65 and the upper end (end on the opening 61 side) of the storage bag 90 is the same as the distance from the lower end to the tip end portion 44, and the opening 61 is sealed. Then, as shown below the arrow, the electronic endoscope 10 together with the storage bag 90 is turned upside down, and the air in the space 91 between the liquid surface of the moisturizing liquid 65 and the opening 61 is moved toward the distal end portion 44 side. Thereby, the 1st, 2nd accommodating parts 62 and 63 are formed. In this case, it is preferable to provide a hook hole 92 or the like for hanging on the hook at the lower end of the storage bag 90 in order to maintain the inverted hanging state.

  In the example shown in FIG. 11, a hook hole 92 is provided at the lower end of the storage bag 90, a hook 93 (or a hook hole is acceptable) at the upper end, and an openable / closable opening 94 is provided at the lower end. Then, after the electronic endoscope 10 is stored in the storage bag 90 with the distal end portion 44 set to the lower end side of the storage bag 90, the distal end portion 44 becomes slightly higher than the upper end using the hook holes 92 and hooks 93. Thus, the storage bag 90 and the insertion portion 40 are bent in a U shape and suspended. Next, the lower end opening 94 is opened, and the moisturizing liquid 65 is injected until the liquid surface of the moisturizing liquid 65 comes to the upper end (the joint between the operation unit 41 and the insertion unit 40) and the front end 44. Thereby, the 1st, 2nd accommodating parts 62 and 63 are formed. When the injection of the moisturizing liquid 65 is completed, the opening 94 is closed together with the opening 61.

  Alternatively, after the electronic endoscope 10 is accommodated in the storage bag 90 with the distal end portion 44 set to the lower end side of the storage bag 90, the liquid of the moisturizing liquid 65 is closed as in the example shown in FIG. The moisturizing liquid 65 is injected until the distance between the surface and the upper end of the storage bag 90 is approximately the same as the distance from the lower end to the tip portion 44. Next, as in the example shown in FIG. 11, the insertion portion 40 is bent into a U shape and suspended together with the storage bag 90 so that the tip portion 44 is slightly higher than the upper end, and then the opening 94 is opened. Thus, the first and second storage portions 62 and 63 may be formed.

  In the example shown in FIG. 12, similarly to the example shown in FIG. 11, a hook hole 92 is provided at the lower end of the storage bag 90 and a hook 93 is provided at the upper end, but no opening 94 is provided at the lower end. In this case, the electronic endoscope 10 is stored in the storage bag 90 so that the forceps opening 47 is exposed to the outside. Hereinafter, according to the same procedure as the example described in the paragraph [0076], the lower end of the storage bag 90 is connected to the outside through the forceps channel, so that the same state as the example shown in FIG. 11 can be obtained. . In the case of using the example described in paragraph [0077], the moisturizing liquid 65 is injected and the insertion portion 40 is suspended, and then air is sent from the forceps port 47 to the lower end, thereby the first and second storage portions 62. , 63 are formed.

  In the example shown in FIGS. 10 to 12, since there is no seal part 64, the moisturizing liquid 65 may be slightly applied to the tip part 44 due to shaking during transportation, but the tip part 44 is always immersed in the moisturizing liquid 65. Compared to the case, there is less risk of problems. On the contrary, the tip end portion 44 is appropriately moisturized, and it is possible to prevent body fluid and filth from sticking. If the example shown in FIGS. 10-12 is employ | adopted, the effort which press-fits the front-end | tip part 44 in the pressure inlet 67 can be saved.

  In the above embodiment, the size of the storage bag is not strictly defined, but if the type of electronic endoscope is different, the length of the insertion portion and the diameter of the distal end portion are naturally different, and the storage bag is also of the electronic endoscope. It is necessary to prepare for each type.

  However, if a storage bag is prepared for each type of electronic endoscope, it is costly and cumbersome to manage, which is not a good solution. As a solution to this problem, for example, a part of the storage bag is formed of a stretchable material, or a stretchable structure (such as a bellows) is formed to absorb the difference in the length of the insertion portion. Can be considered. It is also conceivable to increase the allowable range of the pressure inlet to absorb the difference in the diameter of the tip. In the example shown in FIGS. 10 to 12, it can be handled in any way by adjusting the hanging position and the injection amount of the moisturizing liquid 65, so there is no need to consider the dimensions of the storage bag.

  In the above embodiment, the total number of returnable bags 30 stored in the rack 20 is 24 sets, but is not particularly limited, and can be appropriately changed in units of several to several hundred pieces. . Prepare multiple types of racks with different numbers of storage and use different racks according to the request, assuming large hospital requests from large hospitals and several small hospital requests from small hospitals. Is preferred. In the above embodiment, an example of delivery to one inspection place 11 by one truck 14 has been described. Of course, delivery to a plurality of inspection places 11 by one truck 14 is also possible.

  In the above embodiment, the laboratory 11 is a hospital and a medical examination center. However, the laboratory 11 is a traveling medical examination car in which equipment related to an endoscopic examination is loaded and an endoscopic examination environment is prepared. There may be. In this case, delivery and collection of the electronic endoscope 10 can be performed not by the truck 14 but by a medical examination car. In the above embodiment, the rental contractor 12 mediates the rental of the electronic endoscope 10. However, the rental contractor 12 is abolished and the electronic endoscope is directly connected between the inspection laboratory 11 and the cleaning factory 13. The mirror 10 may be ordered, billed, or paid.
