Description

  The present invention relates to an encapsulating bag for a medical instrument that encloses a medical instrument that is repeatedly used for examination by cleaning and disinfection.

  2. Description of the Related Art Conventionally, electronic endoscopes that can directly observe the inside of a body cavity of a subject have been actively used in the medical field. In the inspection using an electronic endoscope, a flexible elongated insertion portion is inserted into the body from the oral cavity or the like, and the inside of the body cavity is imaged by a solid-state imaging device such as a CCD provided at the distal end of the insertion portion. And the image obtained by imaging is observed with a monitor.

  Contaminants such as mucus, blood, and filth of the subject adhere to the surface of the electronic endoscope used in the examination. In addition, contaminants also enter the channels for air supply and water supply and the channels through which treatment instruments are inserted. Therefore, after the electronic endoscope is used for inspection, cleaning for removing contaminants (so-called pre-cleaning) is immediately performed at the bedside. Then, after pre-cleaning, it can be used again by being subjected to thorough cleaning and disinfection (so-called reprocessing treatment).

  However, reprocessing requires complicated work and a large-scale and expensive dedicated device. For this reason, if an attempt is made to perform not only pre-cleaning but also reprocessing at an individual hospital or other laboratory, the efficiency of the inspection that should be performed due to complicated reprocessing processing is reduced, or the introduction of dedicated equipment is enormous. There are problems such as the need for costs.

  For this reason, rental offices that exclusively perform reprocess processing lend out clean electronic endoscopes that have undergone reprocessing, collect pre-washed used electronic endoscopes, and reprocess them again. Rental services that perform processing have been proposed (see Patent Documents 1 and 2).

  The clean electronic endoscope that has been reprocessed is stored at the rental office until it is delivered to the laboratory. If stored or delivered in an exposed state, microorganisms in the air adhere to and grow on the surface of the electronic endoscope or inside the channel, or dirt such as dust in the air adheres to the surface. There is a risk of contamination again. For this reason, the reprocessed electronic endoscope is stored and delivered in a sealed state in a resin bag.

  In addition, since the used electronic endoscope is pre-cleaned and then collected, the collected electronic endoscope is collected at the rental office. If it is stored or recovered while being exposed, the contaminants that have not been removed by the pre-cleaning may be dried and fixed, resulting in unwashed residues in the reprocessing process. For this reason, the electronic endoscope that has been pre-cleaned is placed in a bag at the time of delivery, stored in a state of being immersed in a disinfecting solution, and then collected.

  By the way, it is assumed that the electronic endoscope is in contact with the air without being kept in a sealed state such as the bag being broken before being delivered to the laboratory. However, it is difficult to visually determine whether the sealed state is maintained. For this reason, it is not noticed that the sealed state is not maintained, and there is a possibility that the inspection is performed with an electronic endoscope contaminated by contact with air. Moreover, even if the sealed state is maintained, there is always anxiety that it is not sealed.

  In addition, it is assumed that after pre-cleaning, the electronic endoscope is immersed in a disinfectant using a torn bag. If the sealed state is not maintained, such as when the bag is torn, even if liquid leakage cannot be confirmed when it is put in the bag, liquid leakage will occur during storage or collection.

  In addition, although the rental service of patent document 1 and 2 can also be applied to medical instruments other than an electronic endoscope, there exists a problem similar to the case of an electronic endoscope also in this case.

  This invention is made | formed in view of the said subject, and aims at making it easy to visually recognize whether the sealed state is maintained in the enclosure bag of a medical device.

  In order to achieve the above object, an encapsulating bag of a medical device of the present invention is a bag body formed of a material having airtightness, and is in a state where the air is extracted and reduced to a first atmospheric pressure or lower than atmospheric pressure. A bag body that encloses a medical device, a barometer that measures the pressure inside the bag body, and a first indicator that displays whether or not the measured value of the barometer is less than or equal to the first pressure. It is characterized by having.

  It is preferable to provide a second indicator that displays whether or not the measured value of the barometer is equal to or lower than a second atmospheric pressure lower than the first atmospheric pressure.

  It is preferable to include a third indicator that displays whether or not a medical instrument is sealed in the bag body at the first atmospheric pressure or lower.

  Another encapsulating bag for a medical device according to the present invention is a bag body formed of an airtight material, and encapsulates the medical device in a state where the air is extracted and reduced to a first atmospheric pressure lower than the atmospheric pressure. A first base plate that forms a first space between a main body, a first translucent plate that is deformed by an air pressure inside the bag main body, and the first translucent plate; A first base plate having a first ventilation hole connected to the inside of the bag body, and when the air pressure inside the bag body is reduced below the first air pressure, the first translucent plate is And a first display which is deformed so as to eliminate one space and abuts against the first base plate.

  The surface of the first base plate facing the first translucent plate is colored, and the color of the first base plate visually recognized through the first translucent plate is the first base plate. It is preferable that whether or not one translucent plate is in contact with the first base plate is different.

  A second base plate that forms a second space between the second translucent plate deformed by the air pressure inside the bag body and the second translucent plate, and the interior of the bag body A second base plate having a second vent hole connected to the second translucent plate when the air pressure inside the bag body is reduced to a second air pressure lower than the first air pressure. It is preferable that the second display is deformed so as to eliminate the second space and abuts against the second base plate.

  The surface of the second base plate facing the second translucent plate is colored, and the color of the second base plate that is visually recognized through the second translucent plate is the first base plate. It is preferable that the two translucent plates differ depending on whether they are in contact with the second base plate.

  It is preferable to provide a sealing member that seals the opening of the bag body for taking in and out the medical device.

  The medical instrument enclosed in the bag body is preferably an electronic endoscope.

  According to the present invention, the first indicator for displaying whether or not the pressure inside the bag main body formed of the airtight material is equal to or lower than the first pressure lower than the atmospheric pressure is provided. It is possible to easily recognize whether or not the sealed state is maintained.

[First Embodiment]
As shown in FIG. 1, in the rental service of the electronic endoscope 12, the rental office 13 lends and collects the electronic endoscope 12, and cleans and disinfects the collected electronic endoscope 12. A laboratory 14 such as a hospital or a medical examination center performs an examination using the electronic endoscope 12. The rental service of the electronic endoscope 12 is a low-cost, efficient and hygienic electronic endoscope 12 by renting a clean electronic endoscope 12 from the rental office 13 to the inspection place 14 as necessary. Promote the use of

  The rental establishment 13 and the inspection laboratory 14 are connected to each other via a communication network such as a telephone line or the Internet, and exchange of information such as a rental request and notification of a rental date and a collection date is performed online.

  In the laboratory 14, a doctor determines a necessary examination type based on the information of the subject such as a past illness and a current symptom. The types of examination using the electronic endoscope 12 include, for example, upper digestive tract examination, lower digestive tract examination, bronchial examination, biliary examination, EMR (endoscopic mucosal resection), ESD (endoscopic mucosa). Lower incision detachment). The electronic endoscope 12 used for such various examinations needs to have different shapes and sizes depending on the characteristics of each examination. The inspection place 14 requests the rental establishment 13 to lend the electronic endoscope 12 according to the inspection to be performed via the communication network.

  The electronic endoscope 12 in a state enclosed in the encapsulating bag 31 is delivered from the rental establishment 13 to the inspection office 14. In the inspection place 14, the enclosing bag 31 is opened, and the electronic endoscope 12 is taken out. Then, an examination of the subject using the electronic endoscope 12 is performed, and pre-cleaning of the electronic endoscope 12 is performed after the inspection. That is, contaminants such as the mucous membrane, blood, and filth of the subject adhering to the electronic endoscope 12 in an examination or the like are washed away. The pre-cleaned used electronic endoscope 12 is again enclosed in the encapsulating bag 31 and temporarily stored in a predetermined place, and then collected in the rental office 13.

  The rental endoscope 13 collects the electronic endoscope 12 enclosed in the enclosing bag 31 from the inspection laboratory 14. In the rental office 13, the enclosing bag 31 is opened, and the electronic endoscope 12 is taken out. Then, depending on the type of electronic endoscope 12 and the type of inspection, the degree of contaminants remaining after pre-cleaning, etc., the reprocessed processing such as thorough cleaning and disinfection for the collected used electronic endoscope 12 Is given. The electronic endoscope 12 restored to the state that can be used for the inspection in this manner is again enclosed in the enclosing bag 31 and stored in a predetermined place.

  As shown in FIG. 2, the electronic endoscope 12 includes an insertion portion 21 that is inserted into a body cavity of a subject, an operation portion 22 that is connected to a proximal end portion of the insertion portion 21, and the operation portion 22. And a processor 24 and a light source device (both not shown), and a connector 24 attached to a base end portion of the universal cord 23.

  The insertion part 21 has, for example, an elongated shape with an outer diameter of 6 mm and is covered with a flexible tube. The distal end 21a of the insertion portion 21 is provided with a solid-state imaging device such as a CCD, a forceps outlet that exposes the distal end of the treatment instrument, an ejection nozzle that ejects air or distilled water necessary for inspection, etc. (all not shown). ing.

  Inside the insertion portion 21, there are fine forceps channels for passing the treatment tool, air / water supply channels for feeding air and distilled water into the body cavity of the subject, suction channels for sucking body fluids and the like (both not shown), etc. A simple pipeline is provided.

  The operation unit 22 is provided with a forceps inlet 25 into which a treatment tool is inserted. The distal end of the treatment instrument inserted from the forceps inlet 25 is exposed from the forceps outlet.

  The connector 24 is provided with an air / water supply base 26 connected to an air / water supply pump (not shown). Air or distilled water from the air / water pump is fed into the air / water channel via the air / water base 26 and is ejected from the spray nozzle.

  As shown in FIG. 3, the enclosing bag 31 includes a bag body 32 formed of a material having airtightness and watertightness (for example, a transparent or translucent resin sheet such as polyethylene or polyvinyl chloride), and a bag body. A zipper 33 that opens and closes the opening 32a of the 32, a connection member 34 to which the pump P0 is connected when the air inside the bag body 32 is drawn outside, and a barometer 35 that measures the pressure inside the bag body 32; The display 36 displays the atmospheric pressure state inside the bag body 32 based on the measured value of the barometer 35.

  The zipper 33 is opened and closed when the electronic endoscope 12 is taken in and out. Since the zipper 33 is closed, the airtightness of the bag body 32 is maintained.

  The connection member 34 has a needle hole 34 a that allows communication between the inside and the outside of the bag body 32. The connecting member 34 is formed of a flexible material, and the needle hole 34a is blocked by the bending of the connecting member 34 itself, so that the bag body 32 is kept airtight. The needle hole 34a bends when the ventilation needle P1 connected to the pump P0 is inserted, and communicates the inside and the outside of the bag body 32 via the needle hole 34a. When the pump P0 is driven in a state where the needle P1 is inserted into the needle hole 34a, the air inside the bag body 32 is vented.

  As shown in FIG. 4, in the rental office 13, when the electronic endoscope 12 before use is enclosed in the bag body 32, the air inside the bag body 32 is vented. The inside of the bag body 32 is kept in a vacuum state (for example, an atmospheric pressure of about 0.4 times or less of the atmospheric pressure).

  On the other hand, as shown in FIG. 5, when the electronic endoscope 12 after use is sealed in the bag body at the laboratory 14, the disinfecting liquid 38 is injected into the bag main body 32 and then the disinfecting liquid 38. The air inside the bag body 32 is removed so as not to remove the air. That is, the air inside the bag body 32 is extracted with a weak suction force as compared with the case where the disinfectant 38 is not injected. For this reason, although the inside of the bag main body 32 is kept in a vacuum state, the atmospheric pressure (for example, an atmospheric pressure of about 0.6 times or less of the atmospheric pressure is higher than when the electronic endoscope 12 is sealed before use. ). In this case, the liquid is not necessarily limited to the disinfectant 38 and may be an equivalent liquid / substance for preventing the electronic endoscope 12 from being dried after the pre-cleaning.

  Returning to FIG. 3, a known sensor such as a diffusion type using a piezoresistance effect or a capacitance type using a capacitance change of a capacitor is used for the barometer 35 (for example, JP 2010-002421 A, (See JP 06-109568 A). The display device 36 includes an LED 37 that displays the measurement value of the barometer 35 and an LED control circuit (not shown) that controls the lighting mode of the LED 37 based on the measurement value of the barometer 35.

  The display 36 lights up the LED 37 with a different color according to the measurement value of the barometer 35 and displays the state of the atmospheric pressure inside the bag main body 32, so that the electronic endoscope 12 is normally sealed. Is displayed.

  Specifically, a case where the rental establishment 13 is sealed at a pressure of about 0.4 times or less of the atmospheric pressure and the inspection place 14 is sealed at a pressure of about 0.6 or less of the atmospheric pressure will be described as an example. The indicator 36 is blue when the measured value of the barometer 35 is 0.4 times or less of the atmospheric pressure, the measured value of the barometer 35 exceeds 0.4 times of the atmospheric pressure, and 0.6 of the atmospheric pressure. The LED 37 is turned on in green when the pressure is less than double, and red when the measured value of the barometer 35 exceeds 0.6 times the atmospheric pressure (including the case of atmospheric pressure). That is, the indicator 36 displays whether or not the measured value of the barometer 35 is 0.6 times or less (first atmospheric pressure or less) of the atmospheric pressure, and the measured value of the barometer 35 is 0 of the atmospheric pressure. It is displayed whether or not it is 4 times or less (a second atmospheric pressure lower than the first atmospheric pressure). The following description will be made according to this example.

  As shown in FIG. 6, if the bag body 32 is normally sealed during delivery from the rental office 13, the inside of the bag body 32 is kept in a vacuum state of about 0.4 times or less of the atmospheric pressure, and the LED 37 is Lights blue. On the other hand, if an abnormality occurs in the sealed state or the sealing work is not normally performed, the interior of the bag body 32 is not maintained in a vacuum state, that is, the atmospheric pressure is the same as the atmospheric pressure. LED 37 is lit in red.

  Further, if the bag body 32 is normally sealed at the time of collection from the laboratory 14, the interior of the bag body 32 is kept in a vacuum state of about 0.6 times or less of the atmospheric pressure, and the LED 37 is lit in green. On the other hand, if an abnormality occurs in the sealed state or the sealing work is not normally performed, the interior of the bag body 32 is not maintained in a vacuum state, that is, the atmospheric pressure is the same as the atmospheric pressure. LED 37 is lit in red.

  Next, the display mode of the display 36 in the sealed bag 31 having the above-described configuration will be described with reference to the flowchart of FIG. Before the sealing operation at the rental office 13, the inside of the bag body 32 is in the same atmospheric pressure as the atmospheric pressure, and the LED 37 is lit in red (step (hereinafter abbreviated as S) 11). First, the enclosure operation of the electronic endoscope 12 that has been subjected to the reprocessing process is performed (S12). When properly sealed and kept in a vacuum state of about 0.4 times or less of atmospheric pressure (YES in S13), the LED 37 is lit in blue (S14).

  The electronic endoscope 12 enclosed in the encapsulating bag 31 is delivered to the laboratory 14 upon request (S15). If there is an abnormality in the state of the encapsulating bag 31 (YES in S16), the inside of the bag body 32 is not kept in a vacuum state, that is, the atmospheric pressure is the same as the atmospheric pressure, and the LED 37 is lit in red ( S17). Since the LED 37 is lit in red, it is determined that there is an abnormality in the sealed state, and the electronic endoscope 12 is recovered from the laboratory 14 without being used (S18).

  On the other hand, if there is no abnormality in the state of the encapsulating bag 31 delivered to the inspection laboratory 14 (NO in S16), the inside of the bag body 32 is kept in a vacuum state of about 0.4 times or less of the atmospheric pressure, and the LED 37 Remains illuminated in blue. Since the LED 37 is lit in blue, it is determined that there is no abnormality in the sealed state, and the sealed bag 31 is opened (S19). Thereby, the inside of the bag main body 32 becomes the same atmospheric pressure as the atmospheric pressure, and the LED 37 is lit in red (S20). Then, the inspection is performed with the electronic endoscope 12 taken out from the encapsulating bag 31, and the electronic endoscope 12 is pre-cleaned after the inspection (S21).

  After pre-cleaning, the electronic endoscope 12 is sealed (YES in S22), properly sealed, and kept in a vacuum state of about 0.6 times or less of atmospheric pressure (YES in S23), the LED 37 Lights up in green (S24).

  The used electronic endoscope 12 sealed in the sealing bag 31 is collected from the laboratory 14 (S25). If there is an abnormality in the state of the encapsulating bag 31 (YES in S26), the inside of the bag body 32 is not kept in a vacuum state, that is, the atmospheric pressure is the same as the atmospheric pressure, and the LED 37 is lit in red. (S27).

  On the other hand, when it is not properly encapsulated and is not kept in a vacuum state of about 0.6 times or less of the atmospheric pressure (NO in S23), or when the electronic endoscope 12 is not encapsulated in the first place (in S22) NO), the LED 37 remains lit red (S28). Subsequent S29 is the same as S25.

  As described above, the indicator 36 lights the LED 37 with a different color according to the measured value of the barometer 35 and displays the state of the atmospheric pressure inside the bag body 32. Can be easily recognized.

  Thereby, in the rental establishment 13, it can grasp | ascertain whether it was enclosed correctly at the time of enclosure operation | work. Moreover, when returning, it can grasp | ascertain whether it is enclosed correctly.

  Further, in the inspection place 14, even if the vacuum state is not maintained until it is delivered, and the electronic endoscope 12 may be contaminated by contact with air, the inspection is not noticed. There is no situation to do. Moreover, there is no fear that the vacuum state is not maintained. Furthermore, it can be grasped whether it was correctly enclosed at the time of enclosure work.

[Second Embodiment]
In the first embodiment, when there is an abnormality in the state of the encapsulating bag 31 collected from the inspection laboratory 14 and the LED 37 is lit in red, the location of the responsibility is unknown. That is, it is the responsibility of the inspection laboratory 14 and it is unclear whether it was not properly encapsulated or was not encapsulated in the first place, or it was the responsibility of the recovery company and whether an abnormality occurred during recovery.

  Therefore, in the second embodiment described below, when there is an abnormality in the state of the encapsulating bag 31 collected from the laboratory 14, a display for clarifying the location of the responsibility is performed. In addition, the structure employ | adopted by the said 1st Embodiment and each embodiment shown after this shall be applied mutually in the possible range. In the second embodiment, the description of the same configuration, operation, and effect as in the first embodiment is omitted. In the third embodiment to be described next to the second embodiment, only differences from the second embodiment will be described.

  As shown in FIG. 8, the second embodiment differs from the first embodiment in that the display 36 includes a second LED 39. The display 36 basically turns on the LED 39 in the same manner as the first LED 37. However, when the LED 36 is lit in green instead of red, the indicator 36 does not illuminate in red unless it is lit in blue regardless of the atmospheric pressure inside the bag body 32. . That is, the indicator 36 does not light the LED 39 in the order of red → green → red, even if the LED 39 is lighted in the order of red → green → blue → green → red.

  As shown in FIG. 9, if the bag body 32 is normally sealed during delivery from the rental establishment 13, the inside of the bag body 32 is kept in a vacuum state of about 0.4 times or less of the atmospheric pressure, and the LED 37, 39 lights up in blue / blue. On the other hand, if an abnormality occurs in the sealed state or the sealing work is not normally performed, the interior of the bag body 32 is not maintained in a vacuum state, that is, the atmospheric pressure is the same as the atmospheric pressure. The LEDs 37 and 39 are lit in red / red.

  Further, if the bag body 32 is normally sealed at the time of collection from the laboratory 14, the interior of the bag body 32 is kept in a vacuum state of about 0.6 times or less of the atmospheric pressure, and the LEDs 37 and 39 are green / green. Lights on. On the other hand, when it was normally sealed at the time of sealing but an abnormality occurred in the sealed state at the time of collection, the same pressure as the atmospheric pressure after the inside of the bag body 32 became a vacuum state of about 0.6 times or less of the atmospheric pressure Since it is in a state, the LEDs 37 and 39 are lit in red / green. In the first place, when the sealing operation is not normally performed, the inside of the bag body 32 is in the same atmospheric pressure as the atmospheric pressure from the beginning, and the LEDs 37 and 39 are lit in red / red.

  Next, the display mode of the display 36 in the sealed bag 31 having the above-described configuration will be described with reference to the flowchart of FIG. Prior to the enclosing operation at the rental office 13, the LEDs 37 and 39 are lit in red / red (S31). S32 and S33 are the same as S12 and S13. If YES in S33, the LEDs 37 and 39 are lit in blue / blue (S34).

  S35 and S36 are the same as S15 and S16. If YES in S36, the LEDs 37 and 39 are lit in red / red (S37). S38 is the same as S18.

  On the other hand, in the case of NO in S36, the process proceeds to S39 similar to S19, and the LEDs 37 and 39 are lit in red / red (S40). S41 to S43 are the same as S21 to S23.

  If YES in S42 and YES in S43, the LEDs 37 and 39 are lit in green / green (S44).

  S45 and S46 are the same as S25 and S26. If YES in S46, the LEDs 37 and 39 are lit in red / green (S47).

  On the other hand, if NO in S43 or NO in S42, the LEDs 37 and 39 remain lit red / red (S48). Subsequent S49 is the same as S45.

  As described above, since the indicator 36 includes the second LED 39 for displaying whether or not the sealing operation has been correctly performed at the inspection laboratory 14, the encapsulating bag 31 collected from the inspection laboratory 14. If there is an abnormality in the condition, the responsibility is clarified. In other words, it is the responsibility of the inspection laboratory 14 and it can be seen whether it was not properly sealed or the sealing work was not performed in the first place, or it was the responsibility of the collection company and whether an abnormality occurred during the collection.

  In each of the above-described embodiments, the operation is such that the atmospheric pressure state inside the bag body 32 differs between delivery (about 0.4 times or less of atmospheric pressure) and collection (about 0.6 or less of atmospheric pressure). Based on the above, the case where the LED 37 of the display 36 is lit in three stages (red, green, blue) has been described as an example, but the atmospheric pressure inside the bag body 32 is not different between the delivery time and the collection time. The LED 37 of the display 36 may be lit in two stages (for example, red and blue).

[Third Embodiment]
The enclosing bag 31 of the second embodiment includes a barometer 35 and a display 36 that are more expensive than the bag body 32, and the cost increases. Therefore, in the third embodiment described below, the barometer 35 and the indicator 36, which are expensive, are not provided, and the air pressure state inside the bag body 32 is displayed with a simple configuration. If there is an abnormality in the state of the collected sealed bag 31, the location of the responsibility is displayed.

  As shown in FIG. 11, the enclosing bag 31 of the third embodiment includes the first and second indicators 41 and 42 that display the atmospheric pressure state inside the bag main body 32, and whether the enclosing operation has been normally performed. And a third display 43 for displaying whether or not.

  As shown in FIGS. 12, 13A, and 13B, the first display device 41 includes a disk-shaped base plate 44, an O-ring 45, and a curved translucent plate 46. ing. The base plate 44, the O-ring 45, and the translucent plate 46 have substantially the same outer diameter. In FIGS. 13A and 13B, the left side of the drawing is the upper side, and the right side of the drawing is the lower side.

  The upper surface of the base plate 44 is colored green. The base plate 44 is formed with a vent hole 44a penetrating in the out-of-plane direction. The O-ring 45 is disposed on the upper surface of the base plate 45.

  The translucent plate 46 includes a curved plate body 46a that protrudes upward, and a flange portion 46b that continues to the outer periphery of the plate body 46a. The translucent plate 46 contacts the O-ring 45 at the lower surface of the flange portion 46b. That is, the translucent plate 46 is disposed above the base plate 44 via the O-ring 45. The plate main body 46a bends below the flange portion 46b when a downward force is applied. Then, when the downward force is no longer applied, the original state of being convex upward is restored.

  The storage bag 32 is formed with an attachment opening 32b for attaching the first indicator 41. The attachment opening 32b has a diameter similar to that of the plate body 46a in the translucent plate 46. The first indicator 41 is fixed to the inside of the storage bag 32 with an adhesive (not shown) or the like so that the plate body 46a of the translucent plate 46 is exposed from the mounting opening 32b.

  As shown in FIG. 13A, the first indicator 41 has a space S between a base plate 44 and a translucent plate 46 attached to the base plate 44 via an O-ring 45. . At this time, the green color on the upper surface of the base plate 44 is visually recognized as a light green color through the translucent plate 46 and the space S. In addition, let the state which has the space S be an OFF state.

  The air in the space S of the first indicator 41 moves to the inside of the bag body 32 through the vent hole 44a when the air inside the bag body 32 is removed. As a result, the air pressure in the space S decreases, and a downward force acts on the plate body 46 a of the translucent plate 46. As shown in FIG. 13B, the plate main body 46a bends downward and comes into contact with the upper surface of the base plate 44, and the space S disappears. At this time, blue colored on the upper surface of the base plate 44 is visually recognized as green through the translucent plate 46. Note that a state where there is no space S is referred to as an ON state.

  When the bag body 32 is opened in the ON state shown in FIG. 13B, air flows into the first indicator 41 through the bag body 32, and FIG. It will be in the OFF state shown in A).

  Since the first indicator 41 displays whether or not it is normally sealed during collection from the inspection laboratory 14, the translucent plate 46 has an internal pressure of 0.6 at atmospheric pressure within the bag body 32. The plate main body 46 a is designed to bend downward and come into contact with the upper surface of the base plate 44 when it is less than double. As a result, the first indicator 41 is turned on when it is normally sealed at the time of collection from the laboratory 14 and displays green, and when not sealed normally, it is turned off and displayed in light green. .

  The second display unit 42 has the same configuration as the first display unit 41, and detailed illustration thereof is omitted. However, since the second indicator 42 displays whether or not it is normally sealed at the time of delivery from the rental establishment 13, the translucent plate 46 has a 0. The plate body 46 a is designed to bend downward and come into contact with the upper surface of the base plate 44 in the case of four times or less.

  Further, in order to distinguish the second display 42 from the first display 41, the upper surface of the base plate 44 is colored blue. As a result, the second indicator 42 is turned on and displayed in blue when it is normally sealed at the time of delivery from the rental office 13, and is turned off and displayed in light blue when not normally sealed. To do.

  As shown in FIGS. 14, 15 (A), 15 (B), 15 (C) and 15 (D), the third display 43 has the same configuration as the first display 41. In addition, a vent valve 47 for closing the vent hole 44a of the base plate 44 is provided. Further, in order to distinguish the third display 43 from the first and second displays 41 and 42, the upper surface of the base plate 44 is colored yellow.

  The vent valve 47 includes a plate-shaped valve body 47 a that opens and closes the vent hole 44 a from the lower surface side of the base plate 44, a pressing portion 47 b that is pressed when the vent hole 44 a is opened, and a fixing for fixing to the base plate 44. Part 47c. The vent valve 47 is formed by bending a long metal plate. A portion of the valve body 47a that is folded back with a bulge is a pressing portion 47b, and a tip of the pressing portion 47b is a fixing portion 47c.

  The ventilation valve 47 is attached to the base plate 44 by sandwiching the end of the base plate 44 between the valve main body 47a and the fixing portion 47c. The fixing portion 47 c is disposed so as to be interposed between the base plate 44 and the O-ring 45. The valve body 47a is bent downward by a force acting downward to open the vent hole 44a. Then, when the downward force does not act, the original state is restored and the vent hole 44a is closed.

  As shown in FIG. 15A, the third display device 41 has a space S similarly to the first display device 41. In the space S, the vent hole 44 a is closed by the vent valve 47, and an airtight state is maintained from the inside of the bag body 32.

  A downward force acts on the valve body 47a of the vent valve 47 when the air inside the bag body 32 is extracted. And as shown to FIG. 15 (B), the valve main body 47a bends below and opens the vent hole 44a. Thereby, the air in the space S of the third indicator 43 moves to the inside of the bag body 32 through the vent hole 44a.

  Further, as shown in FIG. 15C, like the first indicator 41, the plate body 46a bends downward and comes into contact with the upper surface of the base plate 44, and the space S is eliminated. Thereby, there is no movement of the air from the 3rd indicator 43 to the inside of the bag main body 32, and a downward force does not act on the valve main body 47a. For this reason, the valve body 47a returns to the original state and closes the vent hole 44a.

  When the bag body 32 is torn or opened in the ON state shown in FIG. 15C, air flows into the bag body 32, but the vent hole 47a is closed by the vent valve 47, No air flows into the third indicator 43. For this reason, the ON state shown in FIG. 15C is maintained. That is, once normally sealed, the ON state is maintained even if the vacuum state cannot be maintained during recovery.

  Thereafter, as shown in FIG. 15D, when the pressing portion 47b is pressed from the outside of the bag body 32, the vent valve 47 is bent and the valve body 47a slides so as to open the vent hole 44a. As a result, the air inside the bag body 32 flows into the third display 43 and is reset to the OFF state.

  Note that the bag body 32 needs to be reset to the OFF state when the bag body 32 is opened. For this reason, it is preferable to arrange | position the 3rd indicator 43 so that the press part 47b may be pressed irrespective of the will of the person who opens at the time of opening of the bag main body 32. FIG. Or you may attach to the bag main body 32 the sensor which detects opening of the bag main body 32, and the means to alert | report when opening is detected.

  And when this reset operation is cancelled | released, as shown to FIG. 15 (A), the valve main body 47a will return to an original state, and will close the vent hole 44a.

  As shown in FIG. 16, when normally delivered from the rental office 13, when the bag body 32 is normally sealed, the inside of the bag body 32 is kept in a vacuum state of about 0.4 times or less of the atmospheric pressure, and each display The containers 41 to 43 are in an ON / ON / ON state. On the other hand, if an abnormality occurs in the sealed state or the sealing work is not normally performed, the interior of the bag body 32 is not maintained in a vacuum state, that is, the atmospheric pressure is the same as the atmospheric pressure. The respective indicators 41 to 43 are in an OFF / OFF / OFF state.

  Further, when the bag body 32 is normally sealed at the time of collection from the inspection laboratory 14, the inside of the bag body 32 is kept in a vacuum state of about 0.6 times or less of the atmospheric pressure. The state is OFF / ON / ON. On the other hand, when it was normally sealed at the time of sealing but an abnormality occurred in the sealed state at the time of collection, the same pressure as the atmospheric pressure after the inside of the bag body 32 became a vacuum state of about 0.6 times or less of the atmospheric pressure Since it is in a state, the respective indicators 41 to 43 are in an OFF / OFF / ON state. In the first place, when the sealing operation is not normally performed, the inside of the bag body 32 is in the same atmospheric pressure as the atmospheric pressure from the beginning, and each of the indicators 41 to 43 is in an OFF / OFF / OFF state. is there.

  Next, the display mode of each of the indicators 41 to 43 in the sealed bag 31 having the above configuration will be described with reference to the flowchart of FIG. Prior to the enclosing operation at the rental office 13, each of the indicators 41 to 43 is in an OFF / OFF / OFF state (S51). S52 and S53 are the same as S32 and S33. In the case of YES in S53, the respective indicators 41 to 43 are turned on / on / on (S54).

  S55 and S56 are the same as S35 and S36. In the case of YES in S56, the respective indicators 41 to 43 are turned off / off / on (S57). S58 is the same as S38.

  On the other hand, in the case of NO in S56, the process proceeds to S59, which is the same as S39, and the respective indicators 41 to 43 are in the OFF / OFF / OFF state. S61 to S63 are the same as S41 to S43.

  In the case of YES in S62 and YES in S63, the respective indicators 41 to 43 are in an OFF / OFF / ON state (S64).

  S65 and S66 are the same as S45 and S46. In the case of YES in S66, the respective indicators 41 to 43 are turned off / off / on (S67).

  On the other hand, if NO in S63 or NO in S62, the respective indicators 41 to 43 remain in the OFF / OFF / OFF state (S68). Subsequent S69 is the same as S65.

  As described above, the bag main body 32 has the simple configuration of the first to third displays 41 to 43 without including the barometer 35 and the display 36 which are more expensive than the bag main body 32. In addition to displaying the atmospheric pressure state in the interior of the container, and displaying the location of responsibility when there is an abnormality in the state of the encapsulating bag 31 collected from the inspection laboratory 14, the same effect as in the second embodiment, low cost realizable.

  In the third embodiment, the atmospheric pressure state inside the bag body 32 is different at the time of delivery (about 0.4 times or less of atmospheric pressure) and at the time of collection (about 0.6 times or less of atmospheric pressure). Based on the operation, the case where two indicators (first and second indicators 41, 42) for displaying the atmospheric pressure state inside the bag body 32 have been described as an example. When the atmospheric pressure state does not differ between the delivery time and the collection time, one display device (for example, the first display device 41) may be provided. The display here does not include the third display 43 that displays whether or not the sealing operation has been performed normally.

  In the rental service in each of the above embodiments, the case where the electronic endoscope 12 is lent is described as an example. However, the present invention is not limited to this, and other medical instruments can be lent. In this case, as with the electronic endoscope 12, other medical instruments are stored, delivered, or collected in a state of being enclosed in the encapsulating bag 31.
