Description

Cleaning and disinfecting equipment and chemical bottle unit

[0001] The present invention relates to a cleaning and disinfecting apparatus for cleaning and disinfecting endoscopes and the like, and to a chemical solution bottle unit that is applied to the cleaning and disinfecting apparatus.

[0002] Medical endoscopes have been widely used for the examination and treatment of the inside of living bodies. After use, endoscopes need to be cleaned and disinfected before the next use. For this reason, a cleaning and disinfecting device (endoscope reprocessor) for cleaning and disinfecting endoscopes and other instruments after use has been put into practical use.

[0003] In general, chemical solutions such as disinfectants used in cleaning and disinfecting devices are supplied to the market in a sealed state in a chemical solution bottle unit, which is generally configured to integrate two chemical solution bottles, each containing a different chemical.

[0004] Various configurations for supplying the chemical liquid in such a chemical liquid bottle unit to a cleaning and disinfecting apparatus have been proposed, for example, in Japanese Patent Nos. 4,823,537 and 5,106,557.

[0005] The cleaning and disinfecting apparatuses disclosed in Japanese Patent Nos. 4,823,537 and 5,106,557, for example, are configured such that, simply by closing the tray on which the chemical solution bottle units are placed, the lids (stoppers) of the chemical solution bottle units can be opened and the chemical solutions in the chemical solution bottle units can be injected into the cleaning and disinfecting apparatus.

[0006] In this case, the user first places a liquid medicine bottle unit filled with liquid medicine in a predetermined position on a tray pulled out from the front panel of the washer / disinfector. The user then pushes the tray back into the washer / disinfector to close it. Inside the washer / disinfector is a mechanism for destroying and opening the lids of the liquid medicine bottle units, such as a blade with a pointed tip. The blade is positioned opposite the lids of the liquid medicine bottle units placed on the tray, and when the tray moves in the closing direction together with the liquid medicine bottle units, the lids of the liquid medicine bottle units are pressed against the blade.

[0007] The blade then breaks the lid and opens the bottle unit, and when the bottle is opened, the liquid medicines in the bottle unit are injected into the designated flow paths in the cleaning and disinfecting apparatus.

[0008] In some cases, the amounts of liquid medicine stored in the bottles of a liquid medicine bottle unit may differ from one another. In such cases, the bottles are formed to have different shapes. For example, the bottles are formed to have different lengths in the tray insertion direction.

[0009] In this case, the caps of the bottles are positioned at different positions relative to the tray insertion direction. Accordingly, the blades for opening the bottles are positioned at different positions relative to the tray insertion direction. Therefore, if two bottles are placed in reverse on the tray, there is a risk that only one bottle will open and the other will not, resulting in the bottles not being opened correctly.

[0010] The present invention has been made in consideration of the above circumstances, and aims to provide a cleaning and disinfecting apparatus and a chemical solution bottle unit that can properly open two chemical solution bottles.

[0011] A cleaning and disinfecting apparatus according to one aspect of the present invention has an apparatus main body, a first storage section capable of storing a first chemical liquid bottle, and a second storage section capable of storing a second chemical liquid bottle having a different shape from the first chemical liquid bottle alongside the first chemical liquid bottle, and is equipped with a tray that can be inserted into the apparatus main body, a first opening section that can open the first lid of the first chemical liquid bottle stored in the first storage section, a second opening section that can open the second lid of the second chemical liquid bottle stored in the second storage section, and a stopper that prevents the tray from being inserted if the first chemical liquid bottle and the second chemical liquid bottle are not correctly positioned on the tray.

[0012] A chemical liquid bottle unit according to one aspect of the present invention is a chemical liquid bottle unit that is inserted into the main body of a disinfection and cleaning apparatus while being housed in a tray, and includes a first chemical liquid bottle, a second chemical liquid bottle having a shape different from that of the first chemical liquid bottle, and a key that can fit into a key groove provided in the tray when the first chemical liquid bottle and the second chemical liquid bottle are in a specific arrangement, and the key allows the first chemical liquid bottle and the second chemical liquid bottle to be housed in the tray only when the key is in a state of engagement with the key groove.

[0014] A first embodiment of the present invention will be described below with reference to Figures 1 to 15. It should be noted that in the following description, the drawings based on each embodiment are schematic, and the relationship between the thickness and width of each part, the thickness ratio of each part, etc. may differ from the actual ones, and the drawings may also include parts with different dimensional relationships and ratios.

[0015] In the following description, the downward direction refers to the direction of gravity (vertically downward), the upward direction refers to the direction opposite to the direction of gravity (vertically upward), and the left-right direction refers to the horizontal direction perpendicular to the vertical direction.

[0016] Here, the cleaning and disinfecting apparatus will be exemplified by an endoscope cleaning and disinfecting apparatus 1, which is an endoscope reprocessor (Automatic Endoscope Reprocessor / AER) shown in Figures 1 and 2. Note that the present embodiment described below is not limited to use with endoscopes, and is a technique that can be applied to various types of cleaning and disinfecting apparatuses.

[0017] The endoscope cleaning and disinfecting apparatus 1 is an apparatus for regenerating contaminated used endoscopes, endoscope parts, accessories, etc. (none of which are shown).

[0018] The regeneration process here is not particularly limited, and may refer to, for example, a rinsing process with water, a cleaning process to remove organic matter and other contaminants, a disinfection process to neutralize specific microorganisms, or a sterilization process to eliminate or kill all microorganisms. Note that the endoscope washer-disinfector 1 may perform a combination of the above processes.

[0019] The accessories are not particularly limited, and examples include a suction button that is attached to the endoscope during use and removed from the endoscope during recycling, an air and water supply button, or a tip cover that covers the tip of the endoscope.

[0020] First, we will explain the configuration of the endoscope washer-disinfector 1. The endoscope washer-disinfector 1 has an apparatus main body 2. The apparatus main body 2 has an operation panel 3, an ID input unit 4, a top cover 5, and a water supply hose connection port 6. Furthermore, the apparatus main body 2 has inside it a chemical bottle mounting device 8 for mounting a chemical bottle unit 7.

[0021] The operation panel 3 is mainly composed of, for example, a touch panel. This operation panel 3 can display various types of information. For example, the operation panel 3 can display various operation buttons. This allows a user or the like to input various instructions to the operation panel 3. When an instruction is input by a user or the like, the operation panel 3 outputs a signal corresponding to the instruction content to a control unit (not shown). Note that the form of the operation panel 3 is not limited to the form shown in FIGS. 1 and 2 , and it may be formed, for example, by an LED panel and a keyboard that allows key input.

[0022] The ID input unit 4 is capable of inputting a user ID. The ID input unit 4 is configured, for example, by an RFID reader capable of reading the user ID from an RFID tag. When the user ID is input, the ID input unit 4 outputs the user ID to the control unit.

[0023] The ID input unit 4 is not limited to an RFID reader, but may be, for example, a barcode reader that reads barcodes or a keyboard that allows key input.

[0024] The top cover 5 is provided on the top of the device main body 2 so as to be able to be opened and closed freely. When the top cover 5 is opened, a processing tank (not shown here) is exposed at the top of the device main body 2. The processing tank is a cleaning and disinfecting tank that accommodates the endoscope and accessories to be regenerated and stores liquids such as cleaning liquid, disinfecting liquid, and rinsing liquid.

[0025] The water supply hose connection port 6 is provided at one corner of the device body 2. The connection port of this water supply hose connection port 6 is connected to a water faucet via a water supply hose (not shown).

[0026] As shown in FIGS. 3 and 4, the liquid medicine bottle unit 7 is a so-called cassette type in which two types of liquid medicine bottles, a first liquid medicine bottle 11 and a second liquid medicine bottle 12, are arranged side by side.

[0027] The first chemical bottle 11 stores, for example, a disinfectant containing concentrated peracetic acid, and the second chemical bottle 12 stores, for example, a buffer.

[0028] That is, the first liquid medicine bottle 11 and the second liquid medicine bottle 12 are liquid medicine containers that store different drugs, namely, the main drug and a buffer.

[0029] 3 and 4, the first liquid medicine bottle 11 has a first container body 13, which is a first bottle body, and a first lid 15. The second liquid medicine bottle 12 has a second container body 14, which is a second bottle body, and a second lid 16. The first and second container bodies 13 and 14 are basically cuboid-shaped, for example.

[0030] The first container body 13 has a first opening 13a for discharging the liquid medicine stored in the first container body 13. The first opening 13a is provided at the tip, which is the first end, of the first container body 13. In this embodiment, the first opening 13a has a substantially cylindrical shape. Here, in this embodiment, the first end of the first container body 13 coincides with one end of the first container body 13 in the direction of the central axis X1. Furthermore, the direction of the central axis X1 coincides with the insertion direction when the liquid medicine bottle unit 7 is inserted into the device main body 2 using the liquid medicine bottle mounting device 8.

[0031] The second container body 14 also has a second opening 14a for discharging the liquid medicine stored in the second container body 14. The second opening 14a is provided at the tip, which is the first end, of the second container body 14. In this embodiment, the second opening 14a has a substantially cylindrical shape. Here, in this embodiment, the first end of the second container body 14 coincides with one end of the second container body 14 in the direction of the central axis X2. Furthermore, the direction of the central axis X2 coincides with the insertion direction when the liquid medicine bottle unit 7 is inserted into the device body 2 using the liquid medicine bottle mounting device 8.

[0032] The first and second lids 15, 16 have, for example, a cylindrical basic shape. The first lid 15 is attached to the first opening 13a. The second lid 16 is attached to the second opening 14a. The first lid 15 and the second lid 16 are attached to the first opening 13a and the second opening 14a by screwing or the like.

[0033] The first lid 15 has a first plug 17 therein. The first plug 17 has, for example, a substantially disk shape. The first plug 17 is integrally formed with the first lid 15 so as to close the inner hole of the first lid 15. As a result, the first plug 17 closes the first opening 13a of the first container body 13 in an airtight and liquid-tight state.

[0034] The second lid 16 has a second plug 18 therein. The second plug 18 has, for example, a substantially disk shape. The second plug 18 is integrally formed with the second lid 16 so as to close the inner hole of the second lid 16. As a result, the second plug 18 closes the second opening 14a of the second container body 14 in an airtight and liquidtight state.

[0035] Here, as shown in Figure 4, the length L1 from the base end, which is the second end of the first container body 13, to the tip (first end) of the first opening 13a is set to be shorter than the length L2 from the base end, which is the second end of the second container body 14, to the tip (first end) of the second opening 14a.

[0036] On the other hand, the first lid 15 and the second lid 16 have the same shape. Therefore, the length L3 from the base end to the tip of the first liquid medicine bottle 11 is set to be shorter than the length L4 from the base end to the tip of the second liquid medicine bottle 12.

[0037] Furthermore, the first and second liquid medicine bottles 11 and 12 are joined together such that the base end of the first container body 13 is aligned with the base end of the second container body 14. That is, the base end surfaces of the first and second container bodies 13 and 14 are arranged on the same plane.

[0038] By configuring the liquid medicine bottle unit 7 in this manner, the second stopper 18 of the second liquid medicine bottle 12 is positioned closer to the tip than the first stopper 17 of the first liquid medicine bottle 11. That is, the second stopper 18 is positioned offset from the first stopper 17 in the direction penetrating the first opening 13a (the direction of the central axis X1 of the first liquid medicine bottle 11). More specifically, the second stopper 18 is positioned offset closer to the tip than the first stopper 17 in the direction of the central axis X1 of the first liquid medicine bottle 11.

[0039] Such a liquid medicine bottle unit 7 is replaceable in the device body 2. That is, the liquid medicine bottle unit 7 used in the recycling process of an endoscope or the like is pulled out from the device body 2, for example, when the next recycling process is performed. Then, a new liquid medicine bottle unit 7 is inserted into the device body 2.

[0040] The liquid medicine bottle mounting device 8 is a device for replaceably installing the liquid medicine bottle unit 7 inside the device main body 2. As shown in Figures 1 and 2, the liquid medicine bottle mounting device 8 is disposed inside the device main body 2 so as to extend in the front-to-rear direction of the device main body 2. Furthermore, the liquid medicine bottle mounting device 8 is inclined at a predetermined angle of elevation so that the base end side is higher than the tip end side. The base end surface of the liquid medicine bottle mounting device 8 disposed in this manner is exposed to the outside through an opening 2a provided in the front panel of the device main body 2.

[0041] As shown in FIG. 5 , the liquid medicine bottle mounting device 8 includes a bottle case 31 and a tray 32 .

[0042] The bottle case 31 has a hollow, generally box-like shape and is fixed inside the device main body 2. The bottle case 31 has an opening 31a at its base into which the front of the liquid medicine bottle unit 7 can be inserted. This allows the bottle case 31 to function as a bottle installation section into which the liquid medicine bottle unit 7 can be installed inside the device main body 2.

[0043] 6 to 10, the bottle case 31 has a first lid receiving pipe 43 and a second lid receiving pipe 44 on the lower side of the front end wall 31b. The first and second lid receiving pipes 43, 44 protrude into the interior of the bottle case 31. Furthermore, the first and second lid receiving pipes 43, 44 are arranged side by side in the left-right direction of the bottle case 31. The first lid receiving pipe 43 and the second lid receiving pipe 44 are fluid path inlets that guide the liquids in the first and second liquid medicine bottles 11, 12 to a liquid medicine tank (not shown).

[0044] As shown in Figure 8, the first lid receiving tube 43 and the second lid receiving tube 44 are cup-shaped into which the first lid 15 of the first liquid medicine bottle 11 and the second lid 16 of the second liquid medicine bottle 12 can be inserted when the liquid medicine bottle unit 7 is installed in the bottle case 31.

[0045] Additionally, a first fluid line 45 and a second fluid line 46 are connected to the first lid receiving pipe 43 and the second lid receiving pipe 44 outside the bottle case 31. The first and second fluid lines 45, 46 are fluid lines formed in a predetermined curved shape so as to communicate with the liquid medicine tank. A first blade 41 and a second blade 42 for opening the first stopper 17 and the second stopper 18 are integrally disposed on the first lid receiving pipe 43 and the second lid receiving pipe 44.

[0046] The first blade 41 corresponds to a specific example of a first opening portion, and the second blade 42 corresponds to a specific example of a second opening portion. The first and second blades 41, 42 are tubular members made of metal, such as stainless steel. The first and second blades 41, 42 have sharp shapes for piercing and breaking the first and second stoppers 17, 18 of the first and second lids 15, 16 inserted into the first and second lid receiving tubes 43, 44. The first blade 41 and the second blade 42 extend from the tip end toward the base end of the bottle case 31. The first blade 41 and the second blade 42 have different lengths. Furthermore, the first blade 41 and the second blade 42 are arranged parallel to each other. As a result, the tip of the first blade 41 and the tip of the second blade 42 are located at different positions in the front-to-rear direction of the bottle case 31.

[0047] 5, the bottle case 31 has a pair of left and right guide rails 33 at the top of the left and right walls. Each guide rail 33 extends in the front-rear direction of the bottle case 31.

[0048] The tray 32 has a bottom plate 35 , a back plate 36 , and a pair of left and right side plates 37 .

[0049] The width of the bottom plate 35 is set to be slightly larger than the width of the liquid medicine bottle unit 7, thereby enabling the tray 32 to place the liquid medicine bottle unit 7. Furthermore, the width of the bottom plate 35 is set to be slightly smaller than the width of the opening 31a of the bottle case 31, thereby enabling the tray 32 to be inserted into the bottle case 31.

[0050] The lower part of the back plate 36 is connected to the base end of the bottom plate 35. This back plate 36 functions as a door that opens and closes the opening 2a of the device main body 2. That is, when the tray 32 is inserted up to the terminal position (tip position) inside the bottle case 31, the back plate 36 closes the opening 2a of the device main body 2 (see FIG. 1). At this time, the back surface of the back plate 36, which is the base end surface of the tray 32, is positioned approximately on the same plane as the front panel of the device main body 2. On the other hand, when the tray 32 is retracted rearward relative to the bottle case 31, the back plate 36 opens the opening 2a of the device main body 2 (see FIG. 2).

[0051] The lower portions of the pair of side plates 37 are connected to the left and right side portions of the bottom plate 35. Furthermore, the base ends of the pair of side plates 37 are connected to the back plate 36. In this way, the side plates 37 position the liquid medicine bottle unit 7 placed on the tray 32 in the left-right direction.

[0052] The upper ends of the pair of side plates 37 are slidably connected to the pair of guide rails 33. This allows the tray 32 to move back and forth relative to the bottle case 31.

[0053] 6, the tray 32 has a first storage section 32a capable of storing the first liquid medicine bottle 11 and a second storage section 32b capable of storing the second liquid medicine bottle 12. The first storage section 32a and the second storage section 32b are storage sections for storing the first liquid medicine bottle 11 and the second liquid medicine bottle 12 constituting the liquid medicine bottle unit 7 in the tray 32 in a state where they are arranged side by side.

[0054] When the tray 32 is inserted to the first insertion position while the first liquid medicine bottle 11 is housed in the first housing portion 32a, the first stopper 17 is broken by the first blade 41. That is, when the tray 32 is inserted to the first insertion position, the first lid 15 of the first liquid medicine bottle 11 is opened. When the first lid 15 is opened, the liquid medicine in the first liquid medicine bottle 11 is guided to the liquid medicine tank via the first lid receiving tube 43 and the first fluid pipeline 45.

[0055] Furthermore, when the tray 32 is inserted to the second insertion position while the second liquid medicine bottle 12 is housed in the second housing portion 32b, the second stopper 18 is broken by the second blade 42. That is, when the tray 32 is inserted to the second insertion position, the second lid 16 of the second liquid medicine bottle 12 is opened. When the second lid 16 is opened, the liquid medicine in the second liquid medicine bottle 12 is guided to the liquid medicine tank via the second lid receiving tube 44 and the second fluid line 46.

[0056] In this embodiment, for example, the first insertion position and the second insertion position are set to the same position as shown in Fig. 8. It is also possible to set the first insertion position and the second insertion position to positions offset from each other in the insertion direction.

[0057] In this type of chemical solution bottle mounting device 8, a stopper 50 is provided inside the bottle case 31. In this embodiment, the stopper 50 is provided, for example, on one of the left and right side plates of the bottle case 31 that is on the side of the first storage section 32a. The stopper 50 is a protrusion that extends, for example, in a direction intersecting the insertion direction of the tray 32 (more specifically, in a direction perpendicular to the insertion direction of the tray 32).

[0058] When the first storage section 32a stores the first liquid medicine bottle 11 and the second storage section 32b stores the second liquid medicine bottle 12 (see FIGS. 7 and 11), the stopper 50 allows the tray 32 to be inserted to the first insertion position and the second insertion position (see FIGS. 8 and 12) without coming into contact with the liquid medicine bottle unit 7. In other words, when the liquid medicine bottle unit 7 is properly set on the tray 32, the stopper 50 allows the first blade 41 to open the first lid 15 and the second blade 42 to open the second lid 16.

[0059] On the other hand, when the second liquid medicine bottle 12 is housed in the first housing portion 32a and the first liquid medicine bottle 11 is housed in the second housing portion 32b (see FIGS. 9 and 13), the stopper 50 comes into contact with the liquid medicine bottle unit 7 and prevents the tray 32 from being inserted beyond a predetermined insertion distance. More specifically, the stopper 50 comes into contact with the second liquid medicine bottle 12 (see FIGS. 10 and 14). This prevents the tray 32 from being inserted to the position where the first blade 41 contacts the second stopper 18 and the position where the second blade 42 contacts the first stopper 17. In other words, when the liquid medicine bottle unit 7 is not properly set on the tray 32, the stopper 50 prevents the first blade 41 from opening the second lid 16 and the second blade 42 from opening the first lid 15.

[0060] In order to realize such a function of the stopper 50, the mounting position of the stopper 50 relative to the bottle case 31, the length of the first blade 41, the length of the second blade 42, the mounting position of the first stopper 17 relative to the first lid 15, and the mounting position of the second stopper 18 relative to the second lid 16, etc. are adjusted in advance.

[0061] 11, a slit 51 extending in the insertion direction of the tray 32 is provided in the side plate 37 on the first storage section 32a side of the tray 32. For example, as shown in FIG. 12, a stopper 50 can be inserted into this slit 51. As a result, the slit 51 prevents interference between the tray 32 and the stopper 50 when the tray 32 is inserted into the device main body 2.

[0062] According to this embodiment, when the first container 32a contains the first liquid medicine bottle 11 and the second container 32b contains the second liquid medicine bottle 12, the stopper 50 allows the tray 32 to be inserted to the first insertion position and the second insertion position without coming into contact with the liquid medicine bottle unit 7. As a result, when the liquid medicine bottle unit 7 is properly set on the tray 32, the first lid 15 and the second lid 16 are properly opened by inserting the tray 32, and the liquid medicine in the first liquid medicine bottle 11 and the liquid medicine in the second liquid medicine bottle 12 can be supplied to the liquid medicine tank.

[0063] On the other hand, when the second liquid medicine bottle 12 is accommodated in the first storage section 32a and the first liquid medicine bottle 11 is accommodated in the second storage section 32b, the stopper 50 comes into contact with the second liquid medicine bottle 12 just before the contact position between the first blade 41 and the second stopper 18 and just before the contact position between the second blade 42 and the first stopper 17, thereby preventing the tray 32 from being inserted. This makes it possible to prohibit the first lid 15 and the second lid 16 from being opened if the liquid medicine bottle unit 7 is not properly set on the tray 32.

[0064] As a result, the first lid 15 and the second lid 16 can be opened properly only when the first chemical liquid bottle 11 and the second chemical liquid bottle 12 are correctly set on the tray 32, and the chemical liquid in the first chemical liquid bottle 11 and the chemical liquid in the second chemical liquid bottle 12 can be reliably supplied to the chemical liquid tank.

[0065] For example, as shown in FIG. 15, in a liquid medicine bottle mounting device 8 that does not have a stopper 50, if the first liquid medicine bottle 11 and the second liquid medicine bottle 12 are not set correctly on the tray 32, there may be cases where only one of the liquid medicine bottles (for example, the second liquid medicine bottle 12) is opened.

[0066] 16, for example, the width of the tip end of the slit 51 can be set wider than the width of the base end in the insertion direction of the tray 32. That is, the slit 51 can be formed in a tapered shape with the width of the tip end set wider than the width of the stopper. By configuring it in this way, the stopper 50 can be easily inserted into the slit 51 when the tray 32 is moved in the insertion direction.

[0067] Furthermore, the stopper 50 can be arranged on the bottle case 31 in a configuration that allows it to move in a direction intersecting the extension direction of the slit 51. For example, the stopper 50 shown in Fig. 16 is arranged on the bottle case 31 in a configuration that allows it to move up and down. By configuring it in this way, the stopper 50 can be more easily inserted into the slit 51 when the tray 32 is moved in the insertion direction.

[0068] 17, for example, the stopper 50 can be disposed on the front end wall 31b of the bottle case 31 instead of on the side panel of the bottle case 31. In this case, the extension direction of the stopper 50 is set to the insertion direction of the tray 32. Even with this configuration, when the liquid medicine bottle unit 7 is not properly set on the tray 32, the stopper 50 can prevent the first blade 41 from opening the second lid 16 and the second blade 42 from opening the first lid 15.

[0069] Next, a second embodiment of the present invention will be described with reference to Figures 18 and 19. This embodiment is provided with a structure for defining the orientation of the drug solution bottle unit 7 when it is stored in the tray 32. Other components that are the same as those in the first embodiment described above will be appropriately designated by the same reference numerals and will not be described again.

[0070] The tray 32 of this embodiment has, for example, a key groove 55, which is a recess, in the side plate 37 on the second storage section 32b side. The key groove 55 is open at the upper end of the side plate 37 and extends in the vertical direction of the side plate 37.

[0071] Furthermore, the liquid medicine bottle unit 7 has, for example, a key 56 which is a protrusion integrally formed on the second liquid medicine bottle 12. This key 56 can fit into the key groove 55 when the first liquid medicine bottle 11 and the second liquid medicine bottle 12 are in a specific arrangement.

[0072] Specifically, when the arrangement of the first and second liquid medicine bottles 11 and 12 matches the arrangement of the first and second storage sections 32a and 32b of the tray 32, the key 56 can fit into the key groove 55. The key 56 allows the first and second liquid medicine bottles 11 and 12 to be stored in the tray 32 only when the key 56 is in the fitted state with the key groove 55 (see FIG. 18 ).

[0073] 19 , when the arrangement of the first and second liquid medicine bottles 11 and 12 is opposite to the arrangement of the first and second storage sections 32 a and 32 b, the key 56 does not fit into the key groove 55. Therefore, the key 56 prohibits the first and second liquid medicine bottles 11 and 12 from being stored in the tray 32.

[0074] With this configuration, if the liquid medicine bottle unit 7 is not properly set on the tray 32, the liquid medicine bottle unit 7 is prohibited from being inserted into the device main body 2. As a result, in this embodiment as well, as in the first embodiment described above, if the liquid medicine bottle unit 7 is not properly set on the tray 32, the first lid 15 and the second lid 16 can be prohibited from being opened.

[0075] 20 and 21, it is also possible to provide a key 57, which is a convex portion, on the tray 32 and a key groove 58, which is a concave portion, on the liquid medicine bottle unit 7. With this configuration, the same effects as those of the above-described embodiment can be achieved.

[0076] The present invention is not limited to the above-described embodiments and modifications, and various modifications and applications can be implemented without departing from the spirit and scope of the invention. Furthermore, the above-described embodiments include inventions at various stages, and various inventions can be extracted by appropriately combining the disclosed multiple constituent elements. For example, if the problem to be solved by the invention can be solved and the effects of the invention can be obtained even if some constituent elements are deleted from all the constituent elements shown in one embodiment, the configuration from which these constituent elements are deleted can be extracted as the invention. Furthermore, constituent elements from different embodiments and modifications can be appropriately combined.
