Description

Technical Field

[0001] This invention relates to a collection kit for transferring a sample (primarily liquid pharmaceuticals) contained in a medical bag to multiple sampling containers. Background Technology

[0002] Blood products include red blood cell preparations, plasma preparations, platelet preparations, and whole blood preparations. Regarding blood products, to ensure safety, small samples may be collected for culture and testing. In culture testing, the sample is collected into a culture bottle (sampling container) and placed in an environment suitable for bacterial growth to detect the presence of pathogens.

[0003] The following describes the procedure for transferring platelet preparations from a medical bag containing platelet preparations (hereinafter referred to as a platelet bag) to two culture flasks, using a medical bag containing platelet preparations as an example.

[0004] A small-capacity collection bag is connected to a platelet bag, and a portion of the platelet preparation from the platelet bag is transferred to the collection bag. The collection bag is then separated from the platelet bag. Next, in a clean bench, the collection bag is connected to a tube extending from a sample collection tube, and a predetermined amount of platelet preparation is transferred from the collection bag to the sample collection tube, using the scale on the sample collection tube as a reference. Then, two culture flasks are sequentially connected to the sample collection tube, and a predetermined amount of platelet preparation is transferred to each culture flask. One of the two culture flasks is for anaerobic culture, and the other is for aerobic culture.

[0006] Patent Document 1: US Patent No. 8777921 Summary of the Invention

[0007] From the perspective of further improving the safety of blood products, culture testing for all blood products is being studied. Therefore, there is a need to improve the operational efficiency of blood product culture testing. Furthermore, when performing culture testing on all products, it is desirable that the apparatus used to dispense blood products into culture bottles have a simple structure and low cost. Additionally, it is desirable to be able to collect predetermined amounts of the sample in multiple sampling containers.

[0008] The purpose of this invention is to solve the above-mentioned problems.

[0009] (1) The present invention provides a collection kit for sequentially collecting a collection object contained in a medical bag into multiple sampling containers, comprising: an inflow tube for connecting the medical bag; and a collection bag formed by overlapping and welding two flexible sheets connected downstream of the inflow tube, the collection bag having: multiple receiving chambers for receiving the collection object; an outflow port for transferring the collection object from the multiple receiving chambers to a plurality of sampling containers; and an exhaust section for discharging air from the interior of the multiple receiving chambers.

[0010] This sampling kit features a single outflow port for sequentially sampling multiple sampling containers, thus simplifying the construction and reducing the cost of sampling kits with multiple chambers. Furthermore, it improves operational efficiency when collecting samples into multiple sampling containers, enabling the collection of a predetermined quantity of samples.

[0011] (2) In the acquisition kit described in (1) above, it may also be provided with a connecting flow path between the plurality of said containment chambers and connecting adjacent containment chambers to each other, wherein the inflow pipe is connected to one of the plurality of containment chambers, and the outflow path connected to the outflow port is connected to one of the plurality of containment chambers or other containment chambers.

[0012] According to this structure, the acquisition kit can be compactly configured in the width direction that intersects the extension direction of the connecting flow path.

[0013] (3) The acquisition kit described in (1) above may also include: a plurality of inflow pipes respectively connected to the plurality of said containment chambers; and an outflow path connecting the plurality of said containment chambers to the outflow port.

[0014] According to this structure, by connecting the medical bag to multiple inflow tubes respectively, the collected object can be contained in multiple containment chambers from each inflow tube.

[0015] (4) In the collection kit described in (1) above, the collection bag may also include: a common flow path connected to the downstream of the inflow pipe; a plurality of branch flow paths branching from the common flow path and respectively connected to the plurality of containment chambers; and an outflow flow path connecting the plurality of containment chambers to the outflow port.

[0016] According to this structure, multiple containment chambers can be used to contain the collected objects through a common flow path.

[0017] (5) In any of the above (1) to (4), the sampling kit may also have a connector connected to the outflow port for sequential installation of multiple sampling containers.

[0018] According to this structure, multiple sampling containers can be easily connected to the outflow port by sequentially installing them on the connector.

[0019] According to the present invention, the collection bag has multiple receiving chambers for accommodating the objects to be collected and an outlet port for transferring the objects from the multiple receiving chambers to the multiple sampling containers respectively. Since there is only one outlet port in the collection kit, the collection kit with multiple receiving chambers can be simplified in construction and reduced in cost. In addition, the work efficiency when collecting objects into multiple sampling containers can be improved, and a predetermined amount of objects can be collected. Attached Figure Description

[0021] like Figure 1 As shown, the acquisition kit 10 of the first embodiment is for... Figure 2 The sample M contained in the medical bag 12 shown is transferred to multiple sampling containers 14 (see reference). Figure 3 A and Figure 3 (B) Use. The sample M is a blood preparation, such as platelet preparations. The sample M can also be a pharmaceutical product other than a blood preparation. The sample M can also be a liquid sample other than a pharmaceutical product. The medical bag 12 can be a blood bag system for centrifuging blood containing multiple components into multiple components with different specific gravities (e.g., three components: light specific gravity component, medium specific gravity component, and heavy specific gravity component, or two components: light specific gravity component and heavy specific gravity component), and storing each component in different bags. In this case, the collection kit 10 can be connected to the blood bag system.

[0022] like Figure 1 As shown, the collection kit 10 includes a medical bag 12 (see reference). Figure 2 The inflow tube 16, collection bag 18, and adapter 20 are connected. The adapter 20 allows for attachment and detachment from the collection bag 18. The following will describe... Figure 1 The extension direction (arrow V direction) of the inflow pipe 16 in the shown acquisition kit 10 is called the vertical direction. The direction orthogonal to the vertical direction (arrow W direction) is defined as the width direction of the acquisition kit 10, and the direction orthogonal to both the vertical and width directions is called the thickness direction of the acquisition kit 10. For example... Figure 1 As shown, the acquisition kit 10 is generally used in a posture where the vertical direction is aligned with the vertical direction.

[0023] The inflow tube 16 is a transparent or translucent medical tube. The inflow tube 16 is formed of a thermoplastic resin such as vinyl chloride resin. The inflow tube 16 can be connected or disconnected from other medical tubes without exposing its interior to external gases by using sterile connection devices or tube sealers.

[0024] The inflow tube 16 has an upstream end 16a and a downstream end 16b. In the initial state where the collection kit 10 is provided as a product, the upstream end 16a is welded and sealed. The downstream end 16b is connected to the upper edge 191 of the collection bag 18 via an adapter 22. The adapter 22 is, for example, a sleeve made of a material harder than the collection bag 18.

[0025] The collection bag 18 is connected downstream of the inflow pipe 16. The collection bag 18 has two flexible sheets 24 that overlap and are fused together in the thickness direction. The collection bag 18 includes multiple receiving chambers 26, an inflow path 28, an exhaust path 30, an outflow path 32, a connecting path 34, an outflow port 36, and an exhaust section 38. A portion of the inflow path 28, the exhaust path 30, the outflow path 32, and the multiple receiving chambers 26 are disposed between the two flexible sheets 24 and bulge outwards in the thickness direction of the collection bag 18.

[0026] The collection bag 18 also includes a first bag 181 and a second bag 182. The first bag 181 and the second bag 182 are arranged separately from each other in the vertical direction. Each of the first bag 181 and the second bag 182 is composed of two flexible sheets 24. The second bag 182 is positioned above the first bag 181. A gap 40 is provided between the first bag 181 and the second bag 182. The gap 40 is a space extending in the width direction between the first bag 181 and the second bag 182.

[0027] It should be noted that the collection bag 18 is not limited to being composed of a first bag 181 and a second bag 182 divided along the vertical direction. For example, the collection bag 18 can also be composed of a single bag. Figure 1 When viewed from the front, the first bag 181 and the second bag 182 are each rectangular in shape, with the width dimension being longer than the vertical dimension. It should be noted that the first bag 181 and the second bag 182 are not limited to being rectangular in shape with a longer dimension in the width direction. For example, the first bag 181 and the second bag 182 can also be rectangular in shape with a longer dimension in the vertical direction relative to the width direction, or they can be rectangular in shape with approximately the same length in both the width and vertical directions.

[0028] Multiple compartments 26 contain the sample M to be collected. The multiple compartments 26 include a first compartment 261 and a second compartment 262. The first compartment 261 is an elliptical shape with its elongated dimension along the width of the first bag 181. The volume of the first compartment 261 is, for example, about 8 mL to about 10 mL. The first compartment 261 temporarily stores the sample M to be collected into the first sampling container 141. It should be noted that the multiple compartments 26 are not limited to having two compartments 26. There may also be three or more compartments 26.

[0029] The second receiving chamber 262 is an elliptical shape with its elongated dimension along the width of the second bag 182. The volume of the second receiving chamber 262 is, for example, approximately 8 mL to approximately 10 mL. The volume of the second receiving chamber 262 is the same as that of the first receiving chamber 261. The second receiving chamber 262 temporarily stores the sample M to be collected into the second sampling container 142. It should be noted that the first receiving chamber 261 and the second receiving chamber 262 are not limited to being elliptical in shape. The first receiving chamber 261 and the second receiving chamber 262 can each be any shape other than an ellipse. Furthermore, the volumes of the first receiving chamber 261 and the second receiving chamber 262 can also be different.

[0030] An inflow path 28 is disposed at one end of the collection bag 18 in the width direction. The inflow path 28 includes a first inflow path 281 provided in the first bag 181, a second inflow path 282 provided in the second bag 182, and an intermediate path 283 provided between the first inflow path 281 and the second inflow path 282. The first inflow path 281 is located inside the first bag 181. The first inflow path 281 includes a flow path body 42 extending in the vertical direction and a reversing portion 44 provided at the lower end of the flow path body 42. The flow path body 42 extends in the vertical direction. The reversing portion 44 extends from the lower end of the flow path body 42 toward the center in the width direction and then reverses upward. The downstream end of the reversing portion 44 is connected to the lower part of the first receiving chamber 261.

[0031] The second inflow path 282 is located inside the second bag 182 and extends vertically. The intermediate flow path 283 is located in the gap 40 and is exposed outside the first bag 181 and the second bag 182.

[0032] The inflow path 28 has an upstream end 28a and a downstream end 28b. The upstream end 28a is located at the upper end of the second inflow path 282. The upstream end 28a is connected to the downstream end 16b of the inflow pipe 16 via a transition member 22. The downstream end 28b is located at the end of the foldback portion 44 of the first inflow path 281. It should be noted that the inflow path 28 is not limited to being connected to the first receiving chamber 261. For example, the inflow path 28 may also be connected to the lower part of the second receiving chamber 262.

[0033] An exhaust flow path 30 is provided in the second bag 182. The exhaust flow path 30 is connected to the uppermost part of the second receiving chamber 262. The upper end of the exhaust flow path 30 is disposed at the upper edge 191 of the second bag 182 and is connected to the exhaust section 38.

[0034] An outflow path 32 is provided in the first bag 181 and extends vertically. The upper end 321 of the outflow path 32 is connected to the lowermost part of the first receiving chamber 261. That is, both the outflow path 32 and the inflow path 28 are connected to the first receiving chamber 261. It should be noted that the outflow path 32 is not limited to being connected to the lowermost part of the first receiving chamber 261. The outflow path 32 only needs to be connected to at least the lower part of the first receiving chamber 261. The lower end 322 of the outflow path 32 is disposed at the lower edge 192 of the first bag 181. The lower end 322 of the outflow path 32 has an outflow port 36. The outflow port 36 is a port for transferring the sampled object M from the first receiving chamber 261 and the second receiving chamber 262 to the plurality of sampling containers 14. It should be noted that the outflow path 32 is not limited to being connected to the first receiving chamber 261. For example, the upper end 321 of the outflow path 32 can also be connected to the lowermost part of the second receiving chamber 262.

[0035] There is only one outlet port 36 on the collection kit 10. That is, there are no more than two outlet ports 36. A connecting part 46 is connected to the outlet port 36. The connecting part 46 protrudes downward from the lower end of the first bag 181. The connecting part 46 has a breakable plug (not shown) inside. In the initial state, the outlet port 36 is sealed by the plug.

[0036] The connecting flow path 34 extends vertically and connects the first receiving chamber 261 and the second receiving chamber 262. The connecting flow path 34 includes a first flow path portion 341 provided in the first bag 181, a second flow path portion 342 provided in the second bag 182, and an exposed portion 343 provided between the first flow path portion 341 and the second flow path portion 342. The lower end of the first flow path portion 341 is connected to the upper part of the first receiving chamber 261. The upper end of the first flow path portion 341 is positioned above the first bag 181. The upper end of the second flow path portion 342 is connected to the lowermost part of the second receiving chamber 262. It should be noted that the upper end of the second flow path portion 342 is not limited to being connected to the lowermost part of the second receiving chamber 262. The upper end of the second flow path portion 342 only needs to be connected to at least the lower part of the second receiving chamber 262. The lower end of the second flow path 342 is disposed below the second bag 182. An exposed portion 343 connects the upper end of the first flow path 341 to the lower end of the second flow path 342. The exposed portion 343 is disposed in the gap 40 of the collection bag 18. A sealing member 48 is provided in the exposed portion 343. The sealing member 48 is, for example, a clamp. The sealing member 48 is configured to cut off the flow of the collected object M within the connecting flow path 34. By clamping the connecting flow path 34 with the sealing member 48, the connection of the connecting flow path 34 is cut off. By releasing the clamping of the sealing member 48 on the connecting flow path 34, the connecting flow path 34 is opened. Furthermore, the sealing member 48 can be attached to and detached from the connecting flow path 34.

[0037] An exhaust vent 38 is provided to expel air from the interior of the first receiving chamber 261 and the second receiving chamber 262. The exhaust vent 38 is connected to the upper end of the exhaust flow path 30 via a mounting member 50. The mounting member 50 provides a liquid-tight and airtight seal between the exhaust vent 38 and the collection bag 18. The exhaust vent 38 has a filter 52 that allows gas to pass through while preventing liquid from passing through. When the main component of the sample M is water, the filter 52 is preferably a hydrophilic filter. In this case, the sample M moves to the filter 52 through the exhaust flow path 30, and when the sample M comes into contact with the filter 52, the pores of the filter 52 are blocked by liquid. After the pores of the filter 52 are blocked, the filter 52 prevents the passage of both gas and liquid. Therefore, leakage of the sample M from the first receiving chamber 261 and the second receiving chamber 262 to the outside is prevented. Furthermore, an example of a sample M whose main component is water is a blood preparation.

[0038] It should be noted that the exhaust section 38 is not limited to a structure that connects to the upper end of the exhaust flow path 30 via the mounting component 50. For example, a filter 52a can also be provided on the flexible sheet 24 of the collection bag 18. Figure 1 (Refer to the double-dotted line shape). In this case, the filter 52a is disposed on the wall of the flexible sheet 24 opposite to the second receiving chamber 262, and the air in the second receiving chamber 262 can be directly discharged to the atmosphere through the filter 52a.

[0039] The connector 20 is connected to the lower end 322 of the outflow path 32 via the connecting member 46. The connector 20 is configured to protrude downward relative to the lower edge 192 of the first bag 181. The connector 20 has a connector body 54 and a connecting tube portion 56 located at the upper end of the connector body 54. The connector 20 is connected to the outflow path 32 by inserting the connecting tube portion 56 into the inner hole of the connecting member 46. The connecting member 46 provides a liquid-tight and airtight seal between the connecting tube portion 56 and the collection bag 18.

[0040] The connector 20 includes a needle 58 and a rubber cover 60 that covers the needle 58. The needle 58 is connected to a connecting tube 56 located inside the connector body 54. When the head of the sampling container 14 is inserted into the connector body 54, the needle 58 will... Figure 3 A and Figure 3 B) The plug (not shown) passes through. With the connection part 46 open, the sampling container 14 is connected to the first receiving chamber 261 via the connecting tube 56 and the needle 58.

[0041] As the needle 58 punctures the plug of the sampling container 14, the rubber cover 60 is compressed by being pushed toward the collection bag 18. The needle 58 passes through the compressed rubber cover 60. As the needle 58 is withdrawn from the plug of the first sampling container 141, the rubber cover 60 stretches with elastic restoring force and covers the needle 58 again.

[0042] Next, the collection method of dispensing the object M into the first sampling container 141 and the second sampling container 142 using the collection kit 10 will be described.

[0043] First, such as Figure 2 As shown, the process of connecting the medical bag 12 to the inflow tube 16 is performed. The operator connects the medical bag 12, which contains the collection object M such as platelet preparations, to the inflow tube 16. At this time, the medical bag 12 is positioned above the collection bag 18. The operator connects the supply tube 62 of the medical bag 12 to the inflow tube 16. At this time, the sealing member 48 is in an open state where the cut-off state of the connection flow path 34 is released.

[0044] Next, the process of transferring the sample M to the first receiving chamber 261 and the second receiving chamber 262 is performed. The sample M is, for example, a liquid and is capable of flow. Therefore, the sample M flows out of the medical bag 12 by gravity and flows into the inflow path 28 via the supply tube 62 and the inflow tube 16. Specifically, the sample M moves downward from the inflow tube 16 along the second inflow path 282, the intermediate flow path 283, and the first inflow path 281 by gravity. The sample M moves upward toward the first receiving chamber 261 via the foldback portion 44 of the first inflow path 281. The sample M flows into the first receiving chamber 261 from the inflow path 28.

[0045] The collected object M flows into the first receiving chamber 261, and the air remaining in the first receiving chamber 261 is forced out towards the second receiving chamber 262 through the connecting flow path 34. The air from the second receiving chamber 262 is discharged to the atmosphere through the exhaust flow path 30 and the filter 52 of the exhaust section 38.

[0046] After the object M is filled into the first receiving chamber 261, the object M moves to the second receiving chamber 262 through the connecting flow path 34. The air remaining in the second receiving chamber 262 is discharged to the atmosphere through the exhaust flow path 30 and the exhaust section 38.

[0047] After the first receiving chamber 261 and the second receiving chamber 262 are filled with the sample M, the sample M flows into the filter 52 via the exhaust flow path 30. When the sample M comes into contact with the filter 52, it is captured and retained by the pores of the filter 52. Thus, the filter 52 intercepts the sample M within the exhaust section 38. Therefore, the exhaust section 38 becomes blocked, preventing the sample M from being discharged to the outside through the filter 52. The first receiving chamber 261 and the second receiving chamber 262 each contain the necessary amount (e.g., about 8 mL to 10 mL) of sample M. The supply of sample M from the medical bag 12 to the collection bag 18 is stopped.

[0048] Next, the medical bag 12 is separated from the inflow tube 16. While separating the inflow tube 16 from the supply tube 62 of the medical bag 12, the upstream end 16a of the inflow tube 16 is sealed by welding. For the welding of the inflow tube 16, a tube sealer such as a high-frequency sealer or an ultrasonic sealer is used. The medical bag 12 separated from the collection kit 10 is stored until the inspection is completed.

[0049] Next, the process of transferring the sampled object M from the first receiving chamber 261 to the first sampling container 141 is carried out. At this time, as... Figure 3As shown in Figure A, the operation is performed with the connection of the flow path 34 cut off by the blocking component 48. That is, the connection between the first receiving chamber 261 and the second receiving chamber 262 is cut off by the blocking component 48, thus preventing the object M to be collected from moving between the first receiving chamber 261 and the second receiving chamber 262.

[0050] Connect the first sampling container 141 to the connector 20. Open the cover 64 of the connector 20 and insert the head of the first sampling container 141 into the interior of the connector body 54. Thereby, the needle 58 located inside the connector body 54 penetrates the plug of the first sampling container 141.

[0051] The operator bends the plug of the connecting component 46 to break it, thus opening the outflow path 32. The sample M in the first receiving chamber 261 is drawn out by the negative pressure in the first sampling container 141 and flows into the first sampling container 141 through the outflow path 32, the outflow port 36, the connecting component 46, the connecting tube 56 of the connector 20, and the needle 58. At this time, because the connection of the connecting path 34 is cut off by the blocking component 48, the sample M in the second receiving chamber 262 is not drawn out through the outflow path 32. Therefore, approximately the entire amount of sample M stored in the first receiving chamber 261 is transferred to the first sampling container 141. The amount of sample M in the first sampling container 141 is, for example, about 8 mL to 10 mL.

[0052] like Figure 3 As shown in Figure B, after the first sampling container 141 is detached from the connector 20, the process of connecting the connector 20 to the second sampling container 142 and transferring the sampled object M from the second receiving chamber 262 to the second sampling container 142 is performed. The connection of the second sampling container 142 is the same as the connection of the first sampling container 141, therefore, a detailed description of the connection between the connector 20 and the second sampling container 142 is omitted.

[0053] After connecting the second sampling container 142, the blocking component 48 is released from the disconnection state of the connecting flow path 34. The connecting flow path 34 is opened, thereby allowing the sample M in the second receiving chamber 262 to be drawn out by the negative pressure within the second sampling container 142. The sample M flows from the second receiving chamber 262 through the connecting flow path 34, the first receiving chamber 261, the outflow flow path 32, the outflow port 36, the connecting component 46, the connecting tube 56 of the connector 20, and the needle 58 into the second sampling container 142. Thus, approximately the entire volume of the sample M stored in the second receiving chamber 262 is transferred to the second sampling container 142. The amount of sample M in the second sampling container 142 is, for example, about 8 mL to 10 mL. The second sampling container 142 is then disconnected from the connector 20. Thus, the collection (sampling) of the sample M using the collection kit 10 is completed. That is, the first sample MS1 is introduced into the first sampling container 141, and the second sample MS2 is introduced into the second sampling container 142.

[0054] When the collected substance M is a blood product, the first sample MS1 and the second sample MS2 are cultured for testing. Specifically, the first sample MS1 in the first sampling container 141 is used for anaerobic culture, for example, to observe whether anaerobic bacteria proliferate. The second sample MS2 in the second sampling container 142 is used for aerobic culture, for example, to observe whether aerobic bacteria proliferate. In both tests, the first sampling container 141 and the second sampling container 142 are used as culture bottles. If the first sample MS1 and the second sample MS2 pass the culture test, the collected substance M in the medical bag 12, which serves as the collection source for the first sample MS1 and the second sample MS2, is judged to be a qualified product. The qualified product is used for the treatment of patients (blood transfusion, etc.).

[0055] The first implementation method has the following effects.

[0056] like Figure 1 As shown, the collection kit 10 includes a collection bag 18 connected downstream of the inflow tube 16. The collection bag 18 has multiple receiving chambers 26 (first receiving chamber 261, second receiving chamber 262) for receiving the collection object M contained in the medical bag 12, and an outflow port 36 for transferring the collection object M from the multiple receiving chambers 26 to multiple sampling containers 14 (first sampling container 141, second sampling container 142) respectively. Figure 3 A and Figure 3 B). Therefore, since there is only one outflow port 36 in the collection kit 10, the collection kit 10 with multiple receiving chambers 26 can be simply constructed and the cost can be reduced. In addition, the work efficiency when collecting the object M into multiple sampling containers 14 can be improved, and a predetermined amount of object M can be collected.

[0057] The collection bag 18 has a connecting flow path 34 disposed between a plurality of receiving chambers 26 and connecting adjacent first receiving chambers 261 and second receiving chambers 262 to each other. An inflow pipe 16 is connected to one of the receiving chambers 26, namely the first receiving chamber 261, and an outflow flow path 32 connected to the outflow port 36 is connected to the first receiving chamber 261 among the receiving chambers 26. Thus, the collection kit 10 can be compactly configured in the width direction of the collection bag 18, which intersects the extending direction of the connecting flow path 34.

[0058] like Figure 3 A and Figure 3 As shown in Figure B, a connector 20 is connected to the outlet port 36, on which a first sampling container 141 and a second sampling container 142 are sequentially mounted. Thus, by mounting multiple sampling containers, namely the first sampling container 141 and the second sampling container 142, to the connector 20, they can be easily connected to the outlet port 36.

[0059] Furthermore, the acquisition kit 10 is not limited to, for example Figure 1 The first receiving chamber 261 and the second receiving chamber 262 are arranged vertically (in the direction of arrow V). For example, Figure 4 The collection kit 101A of the first modified example shown includes a collection bag 18C having a first bag 181A and a second bag 182A. The first bag 181A and the second bag 182A are arranged in the width direction (arrow W direction). The first bag 181A has a first receiving chamber 261. The second bag 182A has a second receiving chamber 262. The first receiving chamber 261 of the first bag 181A and the second receiving chamber 262 of the second bag 182A are connected by a connecting flow path 34A. A sealing member 48 is provided in the connecting flow path 34A. An inflow pipe 16 is connected to the first bag 181A in a manner communicating with the first receiving chamber 261. The second bag 182A has an outflow port 36 and an exhaust section 38. The outflow port 36 communicates with the second receiving chamber 262 and is connected to a connector 20. The exhaust section 38 communicates with the second receiving chamber 262. The connection state between the first receiving chamber 261 and the second receiving chamber 262, which are achieved via the connecting flow path 34A, can be switched using the blocking component 48.

[0060] in addition, Figure 5The collection kit 101B of the second modified example shown includes a collection bag 18D having a first bag 181B and a second bag 182B. The first bag 181B and the second bag 182B are arranged in the width direction (arrow W direction). The first receiving chamber 261 of the first bag 181B and the second receiving chamber 262 of the second bag 182B are connected by a connecting flow path 34B. A sealing member 48 is provided in the connecting flow path 34B. An inflow pipe 16 is connected to the first bag 181B in communication with the first receiving chamber 261. The first bag 181B has an outflow port 36. The outflow port 36 communicates with the first receiving chamber 261 and is connected to a connector 20. The second bag 182B has an exhaust section 38. The exhaust section 38 communicates with the second receiving chamber 262. The communication state between the first receiving chamber 261 and the second receiving chamber 262 via the connecting flow path 34B can be switched using the sealing member 48.

[0061] like Figure 6 As shown, the collection kit 10A of the second embodiment includes a collection bag 18A and a plurality of inflow tubes 16A. The collection bag 18A has a first region 18L and a second region 18R. The first region 18L is the region to the left of the center in the width direction of the collection bag 18A. The second region 18R is the region to the right of the center in the width direction of the collection bag 18A. It should be noted that the same reference numerals are used for structures identical to those in the collection kit 10 of the first embodiment, and detailed descriptions related to the same constituent elements are omitted.

[0062] The plurality of inflow pipes 16A are a first inflow pipe 161 and a second inflow pipe 162. The first inflow pipe 161 and the second inflow pipe 162 extend in the vertical direction and are separated and arranged in parallel in the width direction. It should be noted that the plurality of inflow pipes 16A is not limited to two inflow pipes, namely the first inflow pipe 161 and the second inflow pipe 162. The number of inflow pipes 16A can be three or more, as long as the number of receiving chambers 26 is the same.

[0063] In the width direction of the collection bag 18A, the first inflow pipe 161 is opposite to the first region 18L. The first inflow pipe 161 is disposed in the first region 18L at a position near the center of the collection bag 18A in the width direction. The downstream end 16b of the first inflow pipe 161 is connected to the upper edge 191 of the first region 18L of the collection bag 18A via a connecting member 22. The downstream end 16b of the first inflow pipe 161 is connected to the inflow path 284. In the width direction of the collection bag 18A, the second inflow pipe 162 is opposite to the second region 18R. The second inflow pipe 162 is disposed in the second region 18R at a position near the center of the collection bag 18A in the width direction. That is, in the width direction of the collection bag 18A, the first inflow pipe 161 and the second inflow pipe 162 are disposed adjacent to each other. The downstream end 16b of the second inflow pipe 162 is connected to the upper edge 191 of the second region 18R of the collection bag 18A via a connecting member 22. The downstream end 16b of the second inflow pipe 162 is connected to the inflow path 285.

[0064] The collection bag 18A includes an outflow path 32A connecting the first receiving chamber 261 and the second receiving chamber 262 to the outflow port 36. The outflow path 32A includes a first outflow section 701 connected to the lowermost part of the first receiving chamber 261, a second outflow section 702 connected to the lowermost part of the second receiving chamber 262, and a common connection section 703 connecting the first outflow section 701 and the second outflow section 702. It should be noted that the first outflow section 701 is not limited to being connected to the lowermost part of the first receiving chamber 261. The first outflow section 701 only needs to be connected to at least the lower part of the first receiving chamber 261. Similarly, the second outflow section 702 is not limited to being connected to the lowermost part of the second receiving chamber 262. The second outflow section 702 only needs to be connected to at least the lower part of the second receiving chamber 262.

[0065] The first outlet 701 is connected to the lowermost part of the first receiving chamber 261 and extends in the vertical direction. The lower end of the first outlet 701 extends to the lower edge 192 of the collection bag 18A. The second outlet 702 is connected to the lowermost part of the second receiving chamber 262 and extends in the vertical direction. The lower end of the second outlet 702 extends to the lower edge 192 of the collection bag 18A.

[0066] The common connection portion 703 is exposed on the outside of the collection bag 18A and extends in the width direction. The common connection portion 703 separates downward from the lower edge 192 of the collection bag 18A and is arranged substantially parallel to the lower edge 192. One end of the common connection portion 703 in the width direction is connected to the lower end of the first outflow portion 701. The other end of the common connection portion 703 in the width direction is connected to the lower end of the second outflow portion 702. An outflow port 36 is provided at the center of the common connection portion 703 in the width direction.

[0067] A first blocking member 481 is provided on the common connection portion 703 at a position between the outlet port 36 and the first outlet portion 701. The first blocking member 481 is, for example, a clamp. A second blocking member 482 is provided on the common connection portion 703 at a position between the outlet port 36 and the second outlet portion 702. The second blocking member 482 is, for example, a clamp. The first blocking member 481 can be used to cut off the connection between the first receiving chamber 261 and the outlet port 36. The second blocking member 482 can be used to cut off the connection between the second receiving chamber 262 and the outlet port 36.

[0068] It should be noted that this is not limited to the situation where a portion of the outflow path 32A is exposed outside the collection bag 18A. For example, it can also be as follows: Figure 6 As shown in the double-dotted line shape, the outflow path 32A is entirely contained within and covered by the collection bag 18A.

[0069] Next, the collection method of dispensing the object M into the first sampling container 141 and the second sampling container 142 using the collection kit 10A will be described.

[0070] like Figure 7 As shown in Figure A, the medical bag 12 is connected to the first inflow tube 161. At this time, the connection between the outflow port 36 and the first and second receiving chambers 261 and 262 via the common connection 703 is cut off by the first sealing member 481 and the second sealing member 482.

[0071] The sample M flows out of the medical bag 12 by gravity and moves into the first receiving chamber 261 through the first inlet pipe 161 and the inlet flow path 284. Air in the inlet flow path 284 and the first receiving chamber 261 is discharged to the atmosphere through the first exhaust section 381, which is connected to the first receiving chamber 261. The first receiving chamber 261 is filled with the sample M, and the sample M flows into the first exhaust section 381, thus accommodating the necessary amount of sample M within the first receiving chamber 261.

[0072] Next, as Figure 7As shown in Figure B, the medical bag 12 is separated from the first inlet pipe 161 and connected to the second inlet pipe 162. At this time, the upstream end 16a of the first inlet pipe 161 is sealed by welding. The sample M flows out of the medical bag 12 by gravity and moves through the second inlet pipe 162 and the inlet flow path 285 towards the second receiving chamber 262. Air in the inlet flow path 285 and the second receiving chamber 262 is discharged to the atmosphere through the second exhaust vent 382, ​​which communicates with the second receiving chamber 262. The second receiving chamber 262 is filled with the sample M, and the sample M flows into the second exhaust vent 382, ​​thereby accommodating the necessary amount of sample M in the second receiving chamber 262. It should be noted that the collection kit 10A is not limited to having two exhaust vents, namely the first exhaust vent 381 and the second exhaust vent 382. For example, one exhaust vent may be provided in the exhaust flow path connected to the first receiving chamber 261 and the second receiving chamber 262.

[0073] After separating the medical bag 12 from the second inlet tube 162 and sealing the upstream end 16a of the second inlet tube 162 by welding, as Figure 8 As shown in Figure A, the first sampling container 141 is connected to the connector 20. The operator bends the plug of the connecting component 46 to break it, thereby opening the outflow path 32A. The first blocking component 481 is then released from the cutoff state of the outflow path 32A, thereby allowing the sample M in the first receiving chamber 261 to be sucked out by negative pressure and transferred to the first sampling container 141 through the outflow path 32A, the outflow port 36, and the connector 20.

[0074] Next, after removing the first sampling container 141 from the connector 20, the first sealing component 481 is used to cut off the outflow path 32A again. Figure 8 As shown in Figure B, the second sampling container 142 is connected to the connector 20, and the second sealing component 482 is released from the cutoff state of the outflow path 32A. As a result, the sample M in the second receiving chamber 262 is drawn out by negative pressure and transferred to the second sampling container 142 via the outflow path 32A, the outflow port 36, and the connector 20. At this time, the connection between the first receiving chamber 261 and the outflow path 32A is cut off beforehand using the first sealing component 481. Then, the second sampling container 142 is detached from the connector 20. Thus, the collection (sampling) of the sample M using the sampling kit 10A is completed.

[0075] The second implementation method has the following effects.

[0076] like Figure 7 A and Figure 7As shown in Figure B, the collection kit 10A includes multiple inflow pipes, namely first inflow pipe 161 and second inflow pipe 162, which are respectively connected to multiple receiving chambers, namely first receiving chamber 261 and second receiving chamber 262, and an outflow path 32A connecting the first receiving chamber 261 and second receiving chamber 262 to an outflow port 36. Thus, by connecting the medical bag 12 to the first inflow pipe 161 and second inflow pipe 162 respectively, the collection object M can be received in the first receiving chamber 261 and second receiving chamber 262 from the first inflow pipe 161 and second inflow pipe 162 respectively.

[0077] like Figure 9 As shown, the collection kit 10B of the third embodiment includes an inflow pipe 16B and a collection bag 18B. The collection bag 18B includes an inflow path 28B connected downstream of the inflow pipe 16B and an outflow path 32A connecting the first receiving chamber 261 and the second receiving chamber 262 to the outflow port 36. It should be noted that the same reference numerals are used for structures identical to those in the collection kit 10A of the second embodiment, and detailed descriptions of the same constituent elements are omitted.

[0078] The inflow path 28B has a common flow path 72 and a first branch flow path 741 and a second branch flow path 742 that branch off from the common flow path 72 and are respectively connected to the first receiving chamber 261 and the second receiving chamber 262.

[0079] The common flow path 72 is disposed at the center of the width direction of the collection bag 18B. The common flow path 72 extends from the upper side 191 of the collection bag 18B toward the lower side 192 in the vertical direction.

[0080] The first branch flow path 741 and the second branch flow path 742 are connected to the downstream end of the common flow path 72. The first branch flow path 741 is located in the first region 18L of the collection bag 18B. The first branch flow path 741 has a first reversing portion 761 that extends in the width direction from the common flow path 72 and then turns upward. The first reversing portion 761 is connected to the lower part of the first receiving chamber 261. The second branch flow path 742 is located in the second region 18R of the collection bag 18B. The second branch flow path 742 has a second reversing portion 762 that extends in the width direction from the common flow path 72 and then turns upward. The second reversing portion 762 is connected to the lower part of the second receiving chamber 262. A first inflow-side sealing member 781 is provided on the first branch flow path 741. The first inflow-side sealing member 781 can be used to cut off the communication between the inflow pipe 16B and the first receiving chamber 261. A second inflow-side blocking component 782 is provided on the second branch flow path 742. The second inflow-side blocking component 782 can be used to cut off the connection between the inflow pipe 16B and the second receiving chamber 262.

[0081] Next, the collection method of dispensing the object M into the first sampling container 141 and the second sampling container 142 using the collection kit 10B will be described.

[0082] First, connect the medical bag 12 to the inflow pipe 16B. At this time, open the first inflow-side sealing member 781 to connect the first receiving chamber 261 to the inflow pipe 16B. Open the second inflow-side sealing member 782 to connect the second receiving chamber 262 to the inflow pipe 16B. The sample M flows out of the medical bag 12 by gravity and moves through the inflow pipe 16B, the common flow path 72 of the inflow flow path 28B, the first branch flow path 741, and the second branch flow path 742 towards the first receiving chamber 261 and the second receiving chamber 262. The sample M that moves from the common flow path 72 to the first branch flow path 741 flows into the first receiving chamber 261. The sample M that moves from the common flow path 72 to the second branch flow path 742 flows into the second receiving chamber 262. The collected object M arrives at and flows into the first exhaust section 381 and the second exhaust section 382, ​​filling the first and second accommodating chambers 261 and 262.

[0083] When the sample M from the first receiving chamber 261 is collected into the first sampling container 141, with the first inflow-side blocking member 781 in the off state and the first sampling container 141 connected to the connector 20, the operator bends the plug of the connecting member 46 to break it, thereby opening the outflow path 32A. The off state of the outflow path 32A by the first blocking member 481 is then released. The sample M flows from the first receiving chamber 261 into the first sampling container 141. When the sample M from the second receiving chamber 262 is collected into the second sampling container 142, with the second inflow-side blocking member 782 in the off state and the second sampling container 142 connected to the connector 20, the off state of the outflow path 32A by the second blocking member 482 is released. The sample M flows from the second receiving chamber 262 into the second sampling container 142.

[0084] The third implementation method has the following effects.

[0085] like Figure 9 As shown, the collection bag 18B includes a common flow path 72 connected downstream of the inflow pipe 16B, a first branch flow path 741 and a second branch flow path 742 branching from the common flow path 72 and connected to a plurality of receiving chambers 26 respectively, and an outflow flow path 32A connecting the first receiving chamber 261 and the second receiving chamber 262 to the outflow port 36. Thus, the collection object M can be contained in a plurality of first receiving chambers 261 and second receiving chambers 262 through a single common flow path 72.

[0086] It should be noted that the present invention is not limited to the above disclosure and various structures can be adopted without departing from the spirit of the present invention.
