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, 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 is a collection kit for collecting a collection object contained in a medical bag into multiple sampling containers, comprising: an inflow tube for connecting the medical bag; multiple receiving portions connected downstream of the inflow tube and for receiving the collection object; multiple connectors connected to the multiple receiving portions and for mounting the multiple sampling containers respectively; a flow path switching portion disposed between the inflow tube and the multiple receiving portions and selectively connecting the inflow tube to any one of the multiple receiving portions; and an exhaust portion for discharging air from the interior of the multiple receiving portions.

[0010] According to this collection kit, by having a flow path switching unit for accommodating the collection object into multiple accommodating sections, the work efficiency when collecting the collection object into multiple sampling containers can be improved, and a predetermined amount of collection object can be collected.

[0011] (2) In the collection kit described in (1) above, the plurality of the above-mentioned receiving parts may each include: a transfer pipe for collecting the collection object that has passed through the inflow pipe; and a receiving body that is connected downstream of the transfer pipe and is capable of temporarily storing the collection object, having a receiving chamber with a volume larger than that of the transfer pipe.

[0012] Based on this structure, a predetermined amount of collected objects can be easily stored in the storage chambers of each storage unit.

[0013] (3) In the acquisition kit described in (1) or (2) above, the flow path switching unit may be a plug valve with a switching component having a flow path communicating with the inflow pipe, so as to allow any one of the plurality of the above-mentioned receiving parts to communicate with the inflow pipe via the flow path.

[0014] According to this structure, by activating the switching component of the plug valve, the connection between one of the multiple receiving sections and the inflow pipe can be effectively switched.

[0015] (4) In the acquisition kit described in (2) above, the flow path switching unit has multiple blocking components, which are respectively provided on multiple of the above-mentioned transfer pipes to cut off the connection between the multiple of the above-mentioned receiving parts and the above-mentioned inflow pipes.

[0016] This structure enables the flow path switching unit to be simplified and its cost reduced.

[0017] (5) In any of the above-described (1) to (4), the exhaust section may be provided in each of the multiple containers. Thus, when the object to be collected is contained in the multiple containers, the air in each container can be effectively discharged to the atmosphere.

[0018] According to the present invention, the collection kit includes a flow path switching section disposed between an inflow tube connected to a medical bag and a plurality of receiving portions, which allows the inflow tube to selectively communicate with any one of the plurality of receiving portions. Therefore, by including the flow path switching section for receiving the object to be collected into the plurality of receiving portions, the operational efficiency of collecting the object to be collected into multiple sampling containers mounted on multiple connectors can be improved, and a predetermined amount of the object to be collected can be collected.

[0020] like Figure 1 As shown, the acquisition kit 10 in this embodiment is for the purpose of acquiring... Figure 3 The sample M contained in the medical bag 12 shown is transferred to multiple sampling containers 14 (see reference). Figure 5 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, medium, and heavy, or two components: light and heavy), and separating and storing each component in different bags. In this case, the collection kit 10 can be connected to the blood bag system.

[0021] like Figure 1As shown, the collection kit 10 includes a medical bag 12 (see reference). Figure 3 The system includes an inlet pipe 16, a flow path switching section 18, multiple receiving sections 20, and multiple adapters 22. The following will describe... Figure 1 The direction of extension of the inflow pipe 16 in the acquisition kit 10 shown (arrow V direction) is called the vertical direction. The direction orthogonal to the vertical direction is called the width direction of the acquisition kit 10 (arrow W direction).

[0022] 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 air by using sterile connection devices or tube sealers.

[0023] The inflow pipe 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 flow path switching unit 18.

[0024] A flow path switching unit 18 is disposed between the inlet pipe 16 and the plurality of receiving portions 20. The flow path switching unit 18 allows the inlet pipe 16 to selectively connect to any one of the plurality of receiving portions 20. For example... Figure 2A As shown, the flow path switching unit 18 is a stopcock valve 24. The stopcock valve 24 includes a housing 26 and a switching component 28 housed within the housing 26. Figure 2A In plan view of the shown plug valve 24, the housing 26 is formed into a hollow circular shape. Inside the housing 26 is a receiving space 261 for accommodating the switching component 28.

[0025] The housing 26 has an inlet port 30, a first port 321, and a second port 322. That is, the housing 26 is a three-way plug valve with three ports. The inlet port 30, the first port 321, and the second port 322 protrude radially outward from the outer periphery of the housing 26. The inlet port 30, the first port 321, and the second port 322 communicate with the receiving space 261 of the housing 26.

[0026] The downstream end 16b of the inflow tube 16 is connected to the inlet port 30. The inlet port 30 is the port through which the sample M from the medical bag 12 flows in. A first port 321 is circumferentially separated from the inlet port 30 in the housing 26. The first port 321 is used to transfer the sample M flowing in from the inlet port 30 toward the sampling container 14. A second port 322 is circumferentially separated from both the inlet port 30 and the first port 321 in the housing 26. The second port 322 is used to transfer the sample M flowing in from the inlet port 30 toward the sampling container 14.

[0027] The switching component 28 is circular in shape and rotatably accommodated within the receiving space 261 of the housing 26. The switching component 28 has a flow path 34 communicating with the inlet pipe 16. Viewed in plan view, the flow path 34 is approximately L-shaped. The flow path 34 has a first opening 341 and a second opening 342. The first opening 341 is located at one end of the flow path 34. The second opening 342 is located at the other end of the flow path 34. The first opening 341 and the second opening 342 open on the outer peripheral surface of the switching component 28. The first opening 341 and the second opening 342 are circumferentially separated from each other in the switching component 28.

[0028] The switching component 28 operates such that any one of the plurality of first ports 321 and second ports 322 is connected to the inlet port 30 via the flow path 34. By rotating the switching component 28, any one of the first ports 321 and second ports 322 is selectively connected to the inlet port 30 via the flow path 34. Figure 2A As shown, in the first position of the switching component 28, the stopcock valve 24 connects the inlet port 30 and the first port 321 via the flow path 34. In the first position, the first opening 341 is opposite to the first port 321, and the second opening 342 is opposite to the inlet port 30. In the first position, the switching component 28 cuts off the connection between the inlet port 30 and the second port 322 by blocking the second port 322.

[0029] exist Figure 2B In the second position of the switching component 28 shown, the inlet port 30 and the second port 322 are connected via the flow path 34. In the second position, the first opening 341 is opposite to the inlet port 30, and the second opening 342 is opposite to the second port 322. In the second position, the switching component 28 cuts off the connection between the inlet port 30 and the first port 321 by blocking the first port 321.

[0030] like Figure 1 As shown, multiple receiving sections 20 are connected downstream of the inflow pipe 16 and accommodate the collected object M. Each receiving section 20 has a first receiving section 201 and a second receiving section 202. The first receiving section 201 includes a first transfer pipe 361 connected to the flow path switching section 18 and a first receiving body 381 connected downstream of the first transfer pipe 361. It should be noted that the multiple receiving sections 20 are not limited to two sections. There may also be three or more receiving sections 20.

[0031] The first adapter 361 is a transparent or semi-transparent medical tube. The first adapter 361 is formed of a thermoplastic resin, such as vinyl chloride resin. The upstream end of the first adapter 361 is connected to the first port 321 of the stopcock valve 24. The first container 381 is a cylindrical body having a first receiving chamber 401 inside. The first container 381 is formed of a rigid material (plastic material), such as polypropylene, polyethylene, or polycarbonate. The volume of the first receiving chamber 401 is, for example, about 8 mL to about 10 mL. The first receiving chamber 401 temporarily stores the sample M to be collected from the first sampling container 141, which is one of a plurality of sampling containers 14. The downstream end of the first adapter 361 is connected to one end of the first receiving portion 201. The first adapter 361 communicates with the first receiving chamber 401. At the other end of the first receiving portion 201, a first outflow port 421 is provided for discharging the sample M stored in the first receiving chamber 401. A first outflow port 421 is provided downstream of the first receiving section 201. The first outflow port 421 is not directly connected to the flow path switching section 18.

[0032] The volume of the first receiving chamber 401 is greater than the volume of the first transfer pipe 361. The volume of the first transfer pipe 361 is obtained by multiplying the length of the first transfer pipe 361 along its extension direction by its inner diameter.

[0033] The second connector 362 is a transparent or semi-transparent medical tube. The second connector 362 is formed of a thermoplastic resin, such as vinyl chloride resin. The upstream end of the second connector 362 is connected to the second port 322 of the stopcock valve 24. The second container 382 is a cylindrical body having a second receiving chamber 402 inside. The second container 382 is formed of a rigid material (plastic material), such as polypropylene, polyethylene, or polycarbonate. The volume of the second receiving chamber 402 is, for example, about 8 mL to about 10 mL. The second receiving chamber 402 temporarily stores the sample M to be collected as one of a plurality of sampling containers 14 in the second sampling container 142. The downstream end of the second connector 362 is connected to one end of the second receiving portion 202. The second connector 362 communicates with the second receiving chamber 402. At the other end of the second receiving portion 202, a second outflow port 422 is provided for discharging the sample M stored in the second receiving chamber 402. A second outflow port 422 is provided downstream of the second receiving section 202. The second outflow port 422 is not directly connected to the flow path switching section 18.

[0034] The volume of the second receiving chamber 402 is greater than the volume of the second transfer pipe 362. The volume of the second transfer pipe 362 is obtained by multiplying the length of the second transfer pipe 362 along its extension direction by its inner diameter.

[0035] The first and second containers 381 are not limited to being formed of a cylindrical body. For example, they may also be collection bags made of two flexible sheets overlapped and fused together in the thickness direction, which are containers disposed between the two flexible sheets. In this case, the collection bag is formed of a soft material.

[0036] Connecting members 44 are connected to the first outlet port 421 and the second outlet port 422, respectively. The connecting members 44 protrude outwards from the first and second receptacles 381 and 382. Each connecting member 44 has a breakable plug (not shown) inside. In the initial state, the first outlet port 421 and the second outlet port 422 are sealed by the plugs.

[0037] Multiple connectors 22 are provided for mounting multiple sampling containers 14 respectively. Each connector 22 includes a first connector 221 and a second connector 222. The first connector 221 is connected to the other end of the first container 381 via a connecting member 44. The first connector 221 protrudes relative to the other end of the first container 381. The second connector 222 is connected to the other end of the second container 382 via the connecting member 44. The second connector 222 protrudes relative to the other end of the second container 382. The first connector 221 and the second connector 222 each have a connector body 46 and a connecting tube portion 48 located at the upper end of the connector body 46. The first connector 221 and the second connector 222 are connected to the first container 401 and the second container 402 by inserting the connecting tube portion 48 into the inner hole of the connecting member 44.

[0038] The first connector 221 and the second connector 222 each have a needle 50 and a rubber cover 52 covering the needle 50. The needle 50 is located inside the connector body 46 and connected to the connecting tube 48. When the head of the sampling container 14 is inserted into the connector body 46, the needle 50 will... Figure 5 The plug (not shown) passes through. With the connection part 44 open, the sampling container 14 is connected to the first receiving chamber 401 and the second receiving chamber 402 via the connecting tube 48 and the needle tube 50.

[0039] When the needle 50 punctures the plug of the sampling container 14, the rubber cover 52 is compressed by being pushed toward the first receiving portion 201 and the second receiving portion 202. The needle 50 passes through the compressed rubber cover 52. When the needle 50 is withdrawn from the plug of the first sampling container 141, the rubber cover 52 stretches with elastic restoring force and covers the needle 50 again.

[0040] The acquisition kit 10 further includes a plurality of exhaust sections 54. The plurality of exhaust sections 54 include a first exhaust section 541 provided in the first receiving section 201 and a second exhaust section 542 provided in the second receiving section 202. Furthermore, the number of exhaust sections 54 is the same as the number of receiving sections 20. The first exhaust section 541 is provided for venting air from the interior of the first receiving chamber 401. The first exhaust section 541 is connected to the other end of the first receiving section 201 via a mounting member 55 and communicates with the first receiving chamber 401. The second exhaust section 542 is provided for venting air from the interior of the second receiving chamber 402. The second exhaust section 542 is connected to the other end of the second receiving section 202 via a mounting member 55 and communicates with the second receiving chamber 402.

[0041] The first exhaust section 541 and the second exhaust section 542 are each equipped with a filter 56 that allows gas to pass through but prevents liquid from passing through. When the main component of the sample M is water, the filter 56 is preferably a hydrophilic filter. In this case, the sample M moves through the first receiving chamber 401 and the second receiving chamber 402, and when the sample M comes into contact with the filter 56, the pores of the filter 56 are blocked by liquid. After the pores of the filter 56 are blocked, the filter 56 prevents the passage of both gas and liquid. Therefore, leakage of the sample M from the first receiving chamber 401 and the second receiving chamber 402 to the outside can be prevented. Furthermore, an example of a sample M whose main component is water is a blood preparation.

[0042] Furthermore, the exhaust portion 54 is not limited to a structure in which it is connected to the other ends of the first receiving portion 201 and the second receiving portion 202 via the mounting member 55. The exhaust portion 54 may also be provided on a surface other than the other ends of the first receiving portion 201 and the second receiving portion 202. For example, a filter 56a of the exhaust portion 54 may also be provided on the outer peripheral surface of the first receiving body 381 and the second receiving body 382. Figure 1 (Refer to the double-dotted line in the middle). In this case, the filter 56a is respectively positioned opposite to the first receiving chamber 401 and the second receiving chamber 402, and the air in the first receiving chamber 401 and the second receiving chamber 402 can be directly discharged to the atmosphere through the filter 56a.

[0043] 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.

[0044] First, such as Figure 3 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 target M such as platelet preparations, to the inflow tube 16. At this time, the medical bag 12 is positioned above the collection kit 10. The operator then connects the supply tube 58 of the medical bag 12 to the inflow tube 16.

[0045] Next, the process of transferring the collected object M to the first receiving section 201 (first receiving chamber 401) is carried out. Before transferring the collected object M to the first receiving section 201, the operator rotates the stopcock valve 24 to a first position where the first opening 341 of the flow path 34 is opposite to the first port 321 and the second opening 342 is opposite to the inflow pipe 16. Figure 2A As shown, in the first position, the inflow pipe 16 is connected to the first receiving portion 201 via the flow path 34. In this case, the inflow pipe 16 is not connected to the second receiving portion 202 (second port 322). In addition, the operator performs the operation with the first exhaust portion 541 positioned above the first receiving portion 201.

[0046] 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 moves from the inlet port 30 through the flow path 34 of the stopcock valve 24 and the first port 321 to the first transfer tube 361 via the supply tube 58 and the inlet tube 16. The sample M further flows through the first transfer tube 361 into the first receiving chamber 401 of the first receiving body 381. At this time, because the second port 322 is blocked by the switching component 28, the sample M is prevented from moving from the inlet tube 16 to the second receiving part 202 (the second transfer tube 362).

[0047] When the first exhaust section 541 is positioned above the first receiving section 201, the sample M flows into the first receiving chamber 401. Air remaining in the first transfer pipe 361 and the first receiving chamber 401 is forced upwards within the first receiving chamber 401. The air is then discharged into the atmosphere through the filter 56 of the first exhaust section 541.

[0048] After the first receiving chamber 401 is filled with the sample M, the sample M flows into the filter 56 of the first exhaust section 541. When the sample M comes into contact with the filter 56, it is captured and held by the pores of the filter 56. Thus, the sample M is intercepted within the first exhaust section 541 by the filter 56. Therefore, the first exhaust section 541 becomes blocked, preventing the sample M from being discharged to the outside through the filter 56. The required amount (e.g., about 8 mL to about 10 mL) of the sample M is contained in the first receiving chamber 401. The supply of the sample M from the medical bag 12 to the first receiving section 201 is stopped.

[0049] Next, the process of transferring the collected object M to the second receiving section 202 (second receiving chamber 402) is carried out.

[0050] like Figure 4As shown, the operator rotates the plug valve 24 from position 1 to position 2 (see reference). Figure 2B ).like Figure 2B As shown, in the second position of the switching component 28, the first opening 341 of the flow path 34 faces the inflow pipe 16, and the second opening 342 faces the second port 322 (the second adapter pipe 362), thereby connecting the inflow pipe 16 to the second receiving portion 202. In this case, the inflow pipe 16 is not connected to the first receiving portion 201 (the first port 321). Furthermore, the operator performs the operation with the second exhaust portion 542 positioned above the second receiving portion 202.

[0051] The sample M flows out of the medical bag 12 by gravity and moves from the inlet port 30 to the flow path 34 and second port 322 of the stopcock valve 24 via the supply tube 58 and the inlet tube 16. The sample M further flows from the second port 322 through the second adapter tube 362 into the second receiving chamber 402 of the second receiving section 202. At this time, because the first port 321 is blocked by the switching component 28, the sample M is prevented from moving from the inlet tube 16 to the first receiving section 201. This prevents the sample M contained in the first receiving section 201 from flowing back towards the second receiving section 202.

[0052] When the object M is fed into the second receiving chamber 402 with the second exhaust 542 positioned above the second receiving chamber 202, the air remaining in the second transfer pipe 362 and the second receiving chamber 402 is forced upward within the second receiving chamber 402. The air is then discharged into the atmosphere through the filter 56 of the second exhaust 542.

[0053] After the second receiving chamber 402 is filled with the sample M, the sample M flows into the interior of the second exhaust section 542. When the sample M comes into contact with the filter 56 of the second exhaust section 542, the sample M is captured and held by the pores of the filter 56. Thus, the sample M is intercepted within the second exhaust section 542 by the filter 56. Therefore, the second exhaust section 542 becomes blocked, preventing the sample M from being discharged to the outside through the filter 56. The required amount (e.g., about 8 mL to about 10 mL) of the sample M is contained in the second receiving chamber 402. The supply of the sample M from the medical bag 12 to the second receiving section 202 is stopped.

[0054] It should be noted that the process of transferring the object M to the first receiving section 201 and the second receiving section 202 is not limited to the sequence of transferring the object M to the first receiving section 201 and then to the second receiving section 202. The object M can also be transferred to the second receiving section 202 before being transferred to the first receiving section 201. In this case, the switching component 28 of the stopcock valve 24 switches from the second position to the first position.

[0055] Next, the medical bag 12 is separated from the inflow tube 16. While separating the inflow tube 16 from the supply tube 58 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.

[0056] Next, the process of transferring the sampled object M from the first receiving chamber 401 to the first sampling container 141 is carried out. At this time, as... Figure 5 As shown, the operation is performed with the switching component 28 of the stopcock valve 24 in the second position. That is, the switching component 28 is used to cut off the connection between the inlet port 30 and the first receiving chamber 401. The first sampling container 141 is connected to the first connector 221. The cover 60 of the first connector 221 is opened, and the head of the first sampling container 141 is inserted into the inside of the connector body 46. As a result, the needle 50 located inside the connector body 46 penetrates the plug of the first sampling container 141.

[0057] The operator positions the first sampling container 141 below the first receiving section 201 and bends the plug of the connecting member 44 to break it. This opens the first outflow port 421. The sample M in the first receiving chamber 401 is drawn out by the negative pressure in the first sampling container 141 and flows into the first sampling container 141 through the first receiving chamber 401, the first outflow port 421, the connecting tube 48 of the first connector 221, and the needle tube 50. Thus, approximately the entire amount of sample M stored in the first receiving chamber 401 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 about 10 mL. At this time, the connection between the second receiving section 202 and the first receiving section 201 is cut off by the switching component 28 of the plug valve 24, thus preventing the collected object M in the second receiving chamber 402 from flowing into the first receiving section 201.

[0058] like Figure 6As shown, after detaching the first sampling container 141 from the first connector 221, the process involves connecting the second connector 222 to the second sampling container 142 and transferring the sampled object M from the second receiving chamber 402 to the second sampling container 142. After detaching the first sampling container 141, the switching member 28 is rotated to disconnect the connection between the inflow pipe 16 and the second port 322. It should be noted that 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 second connector 222 and the second sampling container 142 is omitted.

[0059] The operator positions the second sampling container 142 below the second receiving section 202, bends the plug of the connecting member 44 to break it, thereby opening the second outflow port 422. The sample M in the second receiving chamber 402 is drawn out by the negative pressure within the second sampling container 142 and flows into the second sampling container 142 through the second receiving chamber 402, the second outflow port 422, the connecting tube 48 of the second connector 222, and the needle 50. Thus, approximately the entire amount of sample M stored in the second receiving chamber 402 is transferred to the second sampling container 142. The amount of sample M in the second sampling container 142 is, for example, approximately 8 mL to approximately 10 mL. The second sampling container 142 is then removed from the second connector 222.

[0060] Thus, the collection (sampling) of the object 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.

[0061] It should be noted that the process of transferring the sample M to the first sampling container 141 and the second sampling container 142 is not limited to the sequence of transfer from the first receiving chamber 401 to the first sampling container 141 and from the second receiving chamber 402 to the second sampling container 142. The transfer of sample M from the second receiving chamber 402 to the second sampling container 142 may also be performed before the transfer from the first receiving chamber 401 to the first sampling container 141. Alternatively, sample M may be collected in the first receiving chamber 401 first, transferred from the first receiving chamber 401 to the first sampling container 141, and then collected in the second receiving chamber 402 first, and transferred from the second receiving chamber 402 to the second sampling container 142. In this case, the transfer of the sampled object M from the second storage chamber 402 to the second sampling container 142 can also be carried out before the sampled object M is transferred from the first storage chamber 401 to the first sampling container 141.

[0062] When the sample M is a blood preparation, the first sample MS1 and the second sample MS2 are cultured and examined. Specifically, the first sample MS1 (refer to...) in the first sampling container 141... Figure 5 For example, it can be used for anaerobic culture to observe whether anaerobic bacteria proliferate. The second sample MS2 from the second sampling container 142 (refer to...) Figure 6 For example, it can be used for aerobic culture 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 sample M collected 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.).

[0063] This implementation method achieves the following effects.

[0064] like Figure 1 As shown, the collection kit 10 includes a flow path switching unit 18 disposed between an inflow tube 16 connected to a medical bag 12 and a plurality of receiving portions 20 (first receiving portion 201, second receiving portion 202), wherein the inflow tube 16 is selectively connected to any one of the plurality of receiving portions 20 by means of the flow path switching unit 18.

[0065] Therefore, by providing a flow path switching unit 18 for accommodating the object to be collected M into multiple accommodating sections 20, the efficiency of collecting the object to be collected M into multiple sampling containers 14 installed on multiple connectors 22 can be improved, and a predetermined amount of object to be collected M can be collected.

[0066] Each of the multiple receiving sections 20 includes: a transfer pipe 36 (first transfer pipe 361, second transfer pipe 362) for collecting the sample material M that has passed through the inflow pipe 16; and a first receiving body 381 and a second receiving body 382, ​​which are connected downstream of the transfer pipe 36 and can temporarily store the sample material M, and have a first receiving chamber 401 and a second receiving chamber 402 with a volume larger than that of the first transfer pipe 361 and the second transfer pipe 362 respectively. Thus, a predetermined amount of sample material M can be easily stored in the first receiving chamber 401 and the second receiving chamber 402 within the multiple receiving sections 20.

[0067] like Figure 2A As shown, the flow path switching unit 18 is a stopcock valve 24 having a switching component 28, which operates in such a way that any one of the plurality of receiving portions 20 is connected to the inflow pipe 16 via a flow path 34 connected to the inflow pipe 16. Thus, by activating the switching component 28 of the stopcock valve 24, the connection between one of the plurality of receiving portions 20 and the inflow pipe 16 can be effectively switched.

[0068] like Figure 1As shown, the exhaust section 54 is provided in each of the multiple receiving sections 20, so when the object to be collected M is respectively contained in the first receiving chamber 401 and the second receiving chamber 402, the air in the first receiving chamber 401 and the second receiving chamber 402 can be effectively discharged to the atmosphere.

[0069] like Figure 7 As shown, the acquisition kit 10A of the first modification includes multiple receiving portions 20A. The multiple receiving portions 20A connect the flow path switching unit 18 to multiple connectors 22. Each of the multiple receiving portions 20A has multiple receiving tubes 70, each having an internal cavity capable of temporarily storing the acquisition object M. Each receiving tube 70 includes a first receiving tube 701 and a second receiving tube 702. A first connector 221 is connected to the downstream end of the first receiving tube 701, and a second connector 222 is connected to the downstream end of the second receiving tube 702.

[0070] The first receiving tube 701 has a first receiving chamber 721 capable of storing the collected object M. The first receiving chamber 721 is the inner cavity of the first receiving tube 701. A first vent 541 is connected to the first receiving tube 701 via a mounting member 55 and communicates with the first receiving chamber 721. The second receiving tube 702 has a second receiving chamber 722 capable of storing the collected object M. The second receiving chamber 722 is the inner cavity of the second receiving tube 702. A second vent 542 is connected to the second receiving tube 702 via a mounting member 55 and communicates with the second receiving chamber 722. The first receiving tube 701 and the second receiving tube 702 have the same length and inner diameter. The volume of the first receiving chamber 721 of the first receiving tube 701 is, for example, about 8 mL to about 10 mL. The volume of the second receiving chamber 722 of the second receiving tube 702 is, for example, about 8 mL to about 10 mL. It should be noted that the first receiving tube 701 and the second receiving tube 702 are not limited to having the same length and inner diameter. The length and inner diameter of the first receiving tube 701 and the second receiving tube 702 may also be different.

[0071] By setting the switching component 28 of the flow path switching unit 18 to the first position, the collected object M can be temporarily stored in the first receiving chamber 721 of the first receiving tube 701. By setting the switching component 28 of the flow path switching unit 18 to the second position ( Figure 7 (Referring to the shape of the double-dotted line in the middle), the collected object M can be temporarily stored in the second receiving chamber 722 of the second receiving tube 702.

[0072] According to the first modification, by constructing multiple receiving sections 20A using the first receiving tube 701 and the second receiving tube 702, the first connector 221 and the second connector 222 can be directly connected to the flow path switching section 18 using only the first receiving tube 701 and the second receiving tube 702. Therefore, the acquisition kit 10A can be simplified and its cost reduced.

[0073] Figure 8 The acquisition kit 10B of the second variant shown includes a flow path switching unit 18B, which connects the inflow pipe 16 to a plurality of receiving portions 20 and allows the inflow pipe 16 to selectively communicate with any one of the plurality of receiving portions 20. The downstream end 16b of the inflow pipe 16 is connected to the branch portions 80 of the first adapter pipe 361 and the second adapter pipe 362.

[0074] The flow path switching unit 18B includes multiple blocking components 82. Each of the multiple blocking components 82 is, for example, a clamp. Each of the multiple blocking components 82 includes a first blocking component 821 and a second blocking component 822. The first blocking component 821 is provided on the first adapter pipe 361. By clamping the first adapter pipe 361 with the first blocking component 821, the communication between the inflow pipe 16 and the first receiving portion 201 via the first adapter pipe 361 is cut off. The second blocking component 822 is provided on the second adapter pipe 362. By clamping the second adapter pipe 362 with the second blocking component 822, the communication between the inflow pipe 16 and the second receiving portion 202 via the second adapter pipe 362 is cut off. Furthermore, both the first blocking component 821 and the second blocking component 822 can be attached to and detached from their respective adapter pipes on the first adapter pipe 361 and the second adapter pipe 362.

[0075] When transferring the sample M from the medical bag 12 to the first receiving section 201, the first connecting pipe 361 is released by opening the first sealing member 821. The second connecting pipe 362 is then cut off using the second sealing member 822. The inflow pipe 16 is connected to the first receiving section 201 via the first connecting pipe 361. The sample M flowing out of the medical bag 12 moves through the inflow pipe 16, the branch 80, and the first connecting pipe 361 of the first receiving section 201, and is received in the first receiving chamber 401 of the first receiving section 201. At this time, the connection between the inflow pipe 16 and the second receiving section 202 is cut off using the second sealing member 822, thus preventing the sample M from moving to the second receiving section 202.

[0076] When transferring the sample M from the medical bag 12 to the second receiving section 202, the first sealing member 821 cuts off the first transfer pipe 361 and opens the second sealing member 822, thereby releasing the cutoff of the second transfer pipe 362. The inflow pipe 16 connects to the second receiving section 202. The sample M flowing out of the medical bag 12 moves towards the inflow pipe 16, the branch 80, and the second transfer pipe 362 of the second receiving section 202, and is received into the second receiving chamber 402 of the second receiving section 202. At this time, the connection between the inflow pipe 16 and the first receiving section 201 is cut off by the first sealing member 821, thus preventing the sample M from moving towards the first receiving section 201. Furthermore, since the multiple receiving portions 20 and the multiple blocking components 82 are in a corresponding relationship (one blocking component 82 is provided for each receiving portion 20), when more than three receiving portions 20 are provided, the number of blocking components 82 is the same as the number of receiving portions 20.

[0077] The second variation has the following effect.

[0078] By using a flow path switching section 18B composed of multiple blocking components 82 to form the collection kit 10B, the flow path switching section 18B can be simplified and its cost reduced. Compared to the case where the flow path switching section 18 is composed of a stopcock valve 24, the collection kit 10B can be simplified and its cost reduced.

[0079] 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.
