Description

Technical Field

[0001] This disclosure relates to a collection kit for transferring a collection object (primarily a liquid pharmaceutical product) 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. To ensure the safety of blood products, small samples are sometimes 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.

[0005] For example, U.S. Patent No. 8,777,921 discloses a collection kit for collecting samples from medical bags. Existing technical documents Patent documents

[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 that the amount of blood product dispensed into culture bottles be approximately the same. In other words, it is desirable that the amount of sample collected from multiple sampling containers be approximately constant.

[0008] The purpose of this disclosure is to address the aforementioned issues.

[0009] (1) The present disclosure provides a collection kit for collecting an object contained in a medical bag into multiple sampling containers. The collection kit includes an inflow tube for connecting the medical bag and a collection component connected downstream of the inflow tube.

[0010] The collection component has multiple receiving portions and multiple receiving chambers formed inside the multiple receiving portions and accommodating the collection objects. The collection kit further has multiple outflow pipes connected to the multiple receiving chambers and transferring the collection objects from the multiple receiving portions toward the multiple sampling containers, and at least one exhaust portion for discharging air from the interior of the multiple receiving chambers to the exterior of the collection component.

[0011] In the above structure, the collection component is made of a non-flexible material. It should be noted that "the collection component exhibits non-flexibility" means that the collection component possesses rigidity to the extent that it does not substantially deform when the sample flows into each containment chamber and when the sample flows out of each containment chamber into the sampling container. That is, the collection component is made of a rigid material and exhibits sufficient strength during use. The elastic modulus of the material of the collection component is, for example, 20 kg / mm². 2 Therefore, it is difficult to crush the collecting component with your fingers. In this way, the collecting component possesses what is called shape retention. Therefore, each receiving part also possesses shape retention.

[0012] Therefore, based on the above structure, deformation of each receiving part can be suppressed when the sample material flows into each receiving chamber. Thus, the amount of sample material transferred from the medical bag to each receiving chamber becomes approximately the same. That is, the amount of sample material contained in each receiving chamber is fixed. Therefore, the sample amount collected in each sampling container is stable.

[0013] (2) In the acquisition kit described in item (1) above, the acquisition component may have a plurality of inflow pipes provided in each of the plurality ...

[0014] This structure allows for the simultaneous dispensing of sample into multiple chambers. Therefore, the sample volume collected from the sampling containers is more stable. Furthermore, since the inflow pipe is part of the sampling component, it exhibits non-flexibility. Therefore, it is easy to connect branch pipes to the inflow pipe.

[0015] (3) In the acquisition kit described in item (2) above, the multiple inflow pipes may also serve as multiple outflow pipes, and the branch pipes have connecting parts for connecting to outflow ports that are connected to the multiple outflow pipes respectively.

[0016] In this case, the structure of the acquisition components and acquisition kit can be simplified because the number of tubes is reduced.

[0017] (4) In the acquisition kit described in item (2) above, the multiple inflow pipes and the multiple outflow pipes may be separate entities, and a merging pipe connected to the downstream of the multiple outflow pipes may be provided.

[0018] In this case, a connector is connected to the merging pipe, and a sampling container is installed on the connector. After transferring the sample from one of the multiple chambers to the sampling container, another sampling container is installed on the connector, and the sample is transferred from the other of the multiple chambers to that sampling container. As understood from the above, according to this structure, the number of connectors can be reduced to one, thus simplifying the structure of the sampling kit.

[0019] (5) In any of the above items (1) to (4), the collection kit may also have a pipe protection section that covers the inflow pipe.

[0020] Because the inflow tube is surrounded by a protective casing, it is protected against accidental crushing. This prevents the inflow tube from becoming blocked due to crushing. Consequently, the collected sample can be easily transferred from the medical bag to each receiving chamber.

[0021] (6) In the acquisition kit described in item (5) above, the tube protection part may be integrally connected with multiple of the above-mentioned receiving parts.

[0022] It is possible to manufacture a collection component that integrates a tube protection section and multiple receiving sections into one unit. Therefore, compared to manufacturing the tube protection section and multiple receiving sections separately and then connecting the multiple receiving sections to the tube protection section, the collection component can be constructed more efficiently.

[0023] (7) In any of the above items (1) to (6), the material of the collection component may be resin.

[0024] Because resin is lightweight, it allows for the creation of lightweight acquisition kits. Furthermore, because resin is rigid, it is easy to construct non-flexible acquisition components.

[0025] (8) In the collection kit described in item (7) above, the resin may also be transparent or translucent.

[0026] It is possible to easily determine the amount of the collected object contained within the interior (containment chamber) of multiple containment sections.

[0027] (9) In any of the above items (1) to (8), the above exhaust part may have an exhaust pipe, the exhaust pipe having a cylinder body with an opening and a cover that allows the opening of the cylinder body to be opened and closed freely.

[0028] When transferring the sample from the medical bag to each compartment, opening the lid allows air inside each compartment to escape through the openings to the outside of the collection unit. After the transfer of the sample from the medical bag to each compartment is complete, closing the lid maintains the sample within each compartment.

[0029] (10) In the collection kit described in item (9) above, the exhaust stack may also have a hydrophilic filter.

[0030] The hydrophilic filter allows air to pass through before being wetted by the sampled material, and inhibits air passage after the sampled material is wetted. Therefore, even after the sampled material overflows from each chamber and wets the hydrophilic filter, airflow into each chamber is inhibited, even if the cover is opened and air is introduced through the opening. Thus, the sampled material transferred to the sampling container can be used as a specimen for anaerobic culture experiments.

[0031] (11) In any of the above items (1) to (10), the collection kit may also have at least one connector that is connected downstream to the plurality of the above outflow pipes and can be connected to the plurality of the above sampling containers.

[0032] The receiving section and sampling container can be easily connected via the connector through the outflow tube. Furthermore, since the sampling kit includes a connector before use, the operator is spared the effort of connecting each connector to the outflow port individually when using the kit. As a result, sampling operations can be performed efficiently.

[0033] According to this disclosure, the amount of sample material transferred from the medical bag to each of the multiple collection chambers is approximately the same. Therefore, the sample volume of sample material collected from each of the multiple sampling containers is stable. Attached Figure Description

Detailed Implementation

[0035] The top, bottom, left, and right in the following descriptions correspond to... Figure 1 and Figure 2 The top, bottom, left, and right directions correspond as shown. Additionally, "width direction" refers to... Figure 1 and Figure 2 The left and right directions. The "thickness direction" refers to the direction orthogonal to the top and bottom directions and the width direction. Figure 1 , Figure 2 The acquisition kit 10A shown and Figures 10-15 The acquisition kit shown, typically 10B~10G, can... Figure 1 , Figure 2 and Figures 10-15 Use the posture where the vertical direction is aligned with the vertical direction.

[0036] Figure 1 and Figure 2 The sample collection kit 10A shown is for collecting blood products such as platelet preparations. The sample collection object can also be a pharmaceutical product other than a blood product. The sample collection object can also be a liquid sample other than a pharmaceutical product. Medical bag 80 (see reference) Figure 3This can be a blood bag system used to centrifuge blood containing multiple components into several components with different specific gravities (e.g., three components: light, medium, and heavy, or two components: light and heavy), and to separate and store these components in different bags. In this case, the collection kit 10A can be connected to the blood bag system. About Figures 10-15 The acquisition kits 10B~10G shown are the same.

[0037] Hereinafter, in all embodiments from the first to the seventh embodiment, platelet preparation M (see reference) will be used as a blood preparation. Figure 3 The following example illustrates this. Alternatively, blood products collected using collection kits 10A to 10G can also be red blood cell products, plasma products, or whole blood products.

[0038] Collection kits 10A to 10G are used in blood centers and other organizations that manufacture blood products, in culture experiments to confirm the safety of platelet preparation M. In the above methods, Figure 4 and Figure 9 The multiple sampling containers 90 shown (first sampling container 90a and second sampling container 90b) are culture flasks.

[0039] In the culture experiments, both anaerobic and aerobic bacterial cultures were cultured. Therefore, in the culture experiments, a first sampling container 90a for anaerobic culture and a second sampling container 90b for aerobic culture were used. Collection kits 10A~10G were used to collect liquid samples (…). Figure 3 The platelet preparation M shown is used to dispense a predetermined amount into the first sampling container 90a and the second sampling container 90b.

[0040] (1) Structure of the acquisition kit First, refer to Figures 1-3 The acquisition kit 10A of the first embodiment will be described below. Figure 1 and Figure 2 As shown, the acquisition kit 10A includes an inflow pipe 12 and an acquisition component 14A.

[0041] The inflow tube 12 is a transparent or translucent medical tube made of a thermoplastic resin such as vinyl chloride resin. The inflow tube 12 can be connected or disconnected from other medical tubes without exposing its interior to external gases by using a sterile connection device or tube sealer. The inflow tube 12 has an upstream end 12u, a midstream portion 12m, and a downstream end 12d. In the unused state when the collection kit 10A is supplied as a product, the upstream end 12u is welded and sealed. Hereinafter, the unused state will also be referred to as the "initial state". Figure 3As shown, when transferring the platelet preparation M contained in the medical bag 80 to the collection unit 14A, the medical bag 80 is connected to the upstream end 12u of the inflow tube 12.

[0042] Return to Figure 1 and Figure 2 The midstream portion 12m is housed internally from the upper part of the collecting component 14A. The downstream end portion 12d protrudes below the collecting component 14A. The downstream end portion 12d is connected to the collecting component 14A via a branch pipe 16.

[0043] Specifically, branch pipe 16 has a main connecting portion 18a, a first auxiliary connecting portion 18b, and a second auxiliary connecting portion 18c. The downstream end 12d of inflow pipe 12 is connected to the main connecting portion 18a. The first inflow pipe portion 32a constituting the collecting component 14A is connected to the first auxiliary connecting portion 18b. The second inflow pipe portion 32b constituting the collecting component 14A is connected to the second auxiliary connecting portion 18c. As a result, inflow pipe 12 is interconnected with the first inflow pipe portion 32a, and inflow pipe 12 is interconnected with the second inflow pipe portion 32b. The first inflow pipe portion 32a and the second inflow pipe portion 32b constituting inflow pipe portion 32 will be described later.

[0044] The collecting component 14A has a tube protection portion 20 and a plurality of receiving portions 22 provided on the outer side of the tube protection portion 20 in the width direction. For example... Figure 1 As shown, the tube protection section 20 is a cylindrical body. The plurality of receiving sections 22 are also cylindrical bodies with a diameter smaller than that of the tube protection section 20. The tube protection section 20 and the plurality of receiving sections 22 can also be cylindrical bodies with a polygonal shape, such as a quadrangular shape. It should be noted that the tube protection section 20 is not a necessary structure. The plurality of receiving sections 22 can also be integrally connected to each other.

[0045] An insertion hole 24 extending vertically is formed in the pipe protection section 20. The midstream portion 12m of the inflow pipe 12 is inserted into the insertion hole 24. In other words, the midstream portion 12m is covered by the pipe protection section 20. Thus, the midstream portion 12m is protected by the pipe protection section 20. The upstream end 12u of the inflow pipe 12 opens from the upper opening 25a formed on the upper surface of the pipe protection section 20 (see reference). Figure 1 The downstream end 12d of the inflow pipe 12 protrudes downward from the lower opening 25b formed on the lower surface of the pipe protection section 20.

[0046] In the example shown, the plurality of receiving portions 22 have a first receiving portion 22a and a second receiving portion 22b. That is, there are two of the plurality of receiving portions 22. The plurality of receiving portions 22 may also be three or more. The first receiving portion 22a and the second receiving portion 22b are integrally connected with respect to the tube protection portion 20. Alternatively, the tube protection portion 20, the first receiving portion 22a, and the second receiving portion 22b may be made into separate components, and the first receiving portion 22a and the second receiving portion 22b may be individually connected with respect to the tube protection portion 20.

[0047] The first receiving portion 22a is a hollow body and has a first receiving chamber 30a inside. The second receiving portion 22b is also a hollow body and has a second receiving chamber 30b inside. That is, each of the multiple receiving portions 22 has a multiple receiving chamber 30.

[0048] like Figure 9 As shown, the first receiving section 22a and the second receiving section 22b are areas for temporarily storing platelet preparation M transferred to the first sampling container 90a and the second sampling container 90b, respectively. The volume of the first receiving chamber 30a and the volume of the second receiving chamber 30b are, for example, capable of holding approximately 8 mL to approximately 10 mL of platelet preparation M. The volumes of the first receiving chamber 30a and the second receiving chamber 30b are, for example, approximately equal to each other. The volumes of the first receiving chamber 30a and the second receiving chamber 30b may also be different from each other. In the initial state of the collection kit 10A, air is present in the first receiving chamber 30a and the second receiving chamber 30b.

[0049] Return to Figure 1 and Figure 2 The collecting component 14A further includes a first inlet pipe 32a, a first outlet pipe 34a, and a first exhaust pipe 36a. The first inlet pipe 32a and the first outlet pipe 34a are individually connected to the lower part of the first receiving portion 22a. The first exhaust pipe 36a is connected to the upper part of the first receiving portion 22a. Each of the first inlet pipe 32a, the first outlet pipe 34a, and the first exhaust pipe 36a has an inner hole (not shown). Each of the first inlet pipe 32a, the first outlet pipe 34a, and the first exhaust pipe 36a communicates with the first receiving chamber 30a via its respective inner hole.

[0050] The collecting component 14A further includes a second inlet pipe 32b, a second outlet pipe 34b, and a second exhaust pipe 36b. The second inlet pipe 32b and the second outlet pipe 34b are individually connected to the lower part of the second receiving portion 22b. The second exhaust pipe 36b is connected to the upper part of the second receiving portion 22b. Each of the second inlet pipe 32b, the second outlet pipe 34b, and the second exhaust pipe 36b has an inner hole (not shown). Each of the second inlet pipe 32b, the second outlet pipe 34b, and the second exhaust pipe 36b communicates with the second receiving chamber 30b via its respective inner hole.

[0051] As understood above, the collecting component 14A is a single component that integrally comprises the pipe protection section 20, the first receiving chamber 30a, the second receiving chamber 30b, the first inflow pipe section 32a, the second inflow pipe section 32b, the first outflow pipe section 34a, the second outflow pipe section 34b, the first exhaust pipe section 36a, and the second exhaust pipe section 36b. The collecting component 14A (collecting kit 10A) has the first outflow pipe section 34a and the second outflow pipe section 34b as multiple outflow pipe sections 34.

[0052] The collection component 14A thus constructed is non-flexible. Specifically, the collection component 14A is rigid to the extent that it will not deform when transferring platelet preparation M from the medical bag 80 to the first receiving chamber 30a, and also when transferring platelet preparation M from the first receiving chamber 30a toward the first sampling container 90a. The collection component 14A is also rigid to the extent that it will not deform substantially when platelet preparation M flows in or out of the second receiving chamber 30b. The elastic modulus of the material of the collection component 14A is, for example, 20 kg / mm². 2 Therefore, it is difficult to crush the collecting component 14A with your fingers. In this way, the collecting component 14A is made of a rigid material, exhibiting sufficient strength during use.

[0053] The collection component 14A is preferably transparent or translucent. In this case, the operator can easily visually confirm the extent to which the platelet preparation M is contained in the first receiving chamber 30a and the second receiving chamber 30b. In addition, the operator can also easily visually confirm the extent to which the platelet preparation M flows out of the first receiving chamber 30a and the second receiving chamber 30b.

[0054] Resin is a suitable example of a material that meets the above conditions. Resin is lightweight, difficult to break, and easy to process, making it suitable as a material for the collecting component 14A. Typical examples of resins include polycarbonate (PC), polypropylene (PP), polystyrene (PS), polyethylene terephthalate (PET), ethylene glycol-modified polyethylene terephthalate (PETG), and polyvinyl chloride (PVC). However, glass can also be used as a material for the collecting component 14A.

[0055] The collection component 14A further includes an exhaust section 40 for discharging air from inside the first receiving chamber 30a and the second receiving chamber 30b to the outside of the collection component 14A. In the first embodiment, the exhaust section 40 has a first exhaust section 40a located on the upper part of the first receiving chamber 22a and a second exhaust section 40b located on the upper part of the second receiving chamber 22b.

[0056] The first exhaust section 40a has a first exhaust cylinder 42a provided in the first exhaust pipe section 36a. The first exhaust cylinder 42a has a cylinder body 44, a cover 46, and a hydrophilic filter 48. The hydrophilic filter 48 is housed inside the cylinder body 44.

[0057] The hydrophilic filter 48 allows air to pass through before being wetted by the platelet preparation M (which is a liquid), and inhibits air passage after being wetted by the platelet preparation M. Therefore, as the platelet preparation M overflows from the multiple receiving chambers 30 and wets the hydrophilic filter 48, atmospheric air is prevented from passing through the hydrophilic filter 48 and flowing into the multiple receiving chambers 30. In other words, the hydrophilic filter 48 functions as a resistance (block) against the inflow of atmospheric air into the receiving chambers 30.

[0058] The upper end of the cylinder body 44 of the first exhaust stack 42a is an open end with an opening 50. The opening 50 is sealed by a cover 46. For example, the cylinder body 44 and the cover 46 are connected by a hinge (not shown). Therefore, the cover 46 can rotate around the hinge. Alternatively, threaded portions (not shown) may be formed on the outer peripheral surface of the cylinder body 44 and the inner surface of the side peripheral portion of the cover 46, respectively. In this case, the cover 46 is installed on the cylinder body 44 by the threaded portion of the cylinder body 44 engaging with the threaded portion of the cover 46. Consequently, the cover 46 is in a closed state, preventing air from flowing into the interior of the cylinder body 44. On the other hand, as the engagement between the threaded portion of the cylinder body 44 and the threaded portion of the cover 46 is released, the cover 46 is in an open state, allowing air to flow into the interior of the cylinder body 44.

[0059] The second exhaust section 40b has a second exhaust pipe 42b provided on the second exhaust pipe section 36b. The second exhaust pipe 42b is constructed in the same manner as the first exhaust pipe 42a. Therefore, a detailed description of the second exhaust pipe 42b is omitted. The first exhaust pipe 42a and the second exhaust pipe 42b constitute the exhaust pipe 42.

[0060] The acquisition component 14A further includes adapters 60. The number of adapters 60 is the same as the number of receiving portions 22. Therefore, in the example shown, the acquisition kit 10A has two adapters 60. The two adapters 60 have a first adapter 60a and a second adapter 60b. Furthermore, when the acquisition component 14A has three or more receiving chambers 30, the acquisition kit 10A has three or more adapters 60 corresponding to each receiving chamber 30.

[0061] Alternatively, in the initial state of the acquisition kit 10A, the first connector 60a and the second connector 60b are not provided. For example, this can also be done in conjunction with the second embodiment described later (see...). Figure 10 ) and the third embodiment (refer to) Figure 11Similarly, for the first outflow pipe section 34a and the second outflow pipe section 34b, the first connector 310a and the second connector 310b are connected via the first outflow port 300a and the second outflow port 300b. Alternatively, it can be used in conjunction with the fourth and fifth embodiments described later (see...). Figure 12 and Figure 13 Similarly, the connector 310 is connected to the first outflow pipe section 34a and the second outflow pipe section 34b via the branch pipe 17 and the outflow port 300.

[0062] like Figure 2 As shown, a needle unit 62 is provided inside the first connector 60a. The needle unit 62 has: a needle hub 64, which holds a first outflow tube 34a between the first receiving portion 22a and the first connector 60a; a cover member 66 connected to the needle hub 64; a tubular needle portion 68 held in the cover member 66; and a rubber cover 70 covering the needle portion 68. The lower opening of the first connector 60a is sealed by a peeling tab 72.

[0063] The second connector 60b is constructed in the same manner as the first connector 60a. Therefore, a detailed description of the second connector 60b is omitted.

[0064] (2) Structure of the fixture for the acquisition kit Next, refer to Figures 4-7 The clamp 100 for the collection kit is described in detail, which is used to dispense platelet preparation M from collection kit 10A into first sampling container 90a and second sampling container 90b.

[0065] Hereinafter, the direction along the thickness direction of the acquisition kit 10A, and the direction from which the acquisition kit clamp 100 is viewed from the two second support plates 106, will be referred to as the front. The direction along the thickness direction of the acquisition kit 10A, and the direction from which the acquisition kit clamp 100 is viewed from the two first support plates 104, will be referred to as the rear. That is, the two first support plates 104 are located in front compared to the two second support plates 106. Conversely, the two second support plates 106 are located in the rear compared to the two first support plates 104. In addition, the rearward-facing surface of each component will be referred to as the back surface.

[0066] The acquisition kit fixture 100 has a plate-shaped base 102. Two first support plates 104 are erected on the upper surface of the base 102. The two first support plates 104 are arranged parallel to each other and are positioned at the left and right ends of the base 102.

[0067] Two second support plates 106 are erected on the upper surface of the base 102. The two second support plates 106 are arranged parallel to each other. The separation interval between the two second support plates 106 is smaller than the separation interval between the two first support plates 104.

[0068] The collection kit clamp 100 includes a container holding part 220, a kit holding part 110, and a lifting mechanism 150. The container holding part 220 will be described later.

[0069] The kit retainer 110 includes a base portion 112, a first retainer 114a and a second retainer 114b, and a bracket 116. The base portion 112 is positioned and fixed to the upper front surface of the two first support plates 104. The first retainer 114a is positioned and fixed to the left side of the front surface of the base portion 112, and the second retainer 114b is positioned and fixed to the right side of the front surface of the base portion 112. The bracket 116 is positioned and fixed between the first retainer 114a and the second retainer 114b on the front surface of the base portion 112.

[0070] like Figure 5 As shown in the details, a cover 120 is provided on the front surface of the first retainer 114a and the second retainer 114b. A fixing accessory 122 is mounted on the front surface of the cover 120. A hook portion 124 for fixing the fixing accessory 122 is provided on the left side of the front surface of the first retainer 114a. The right side of the front surface of the second retainer 114b is connected to the cover 120 via a hinge 126. Figure 4 The image shows the cover 120 in the closed state with the fastening fitting 122 secured to the hook 124. The cover 120 is preferably transparent or semi-transparent.

[0071] like Figure 6 As shown, the cover 120 has a clamping portion 130 on its back side. The clamping portion 130 has a flat plate portion 132 and a first protruding portion 134a and a second protruding portion 134b. The first protruding portion 134a and the second protruding portion 134b protrude rearward from the back side of the flat plate portion 132. The first protruding portion 134a and the second protruding portion 134b are inclined in a manner that they approach each other as they move from below to above.

[0072] like Figure 5 As shown, the front end of the bracket 116 has an opening 119. The acquisition kit 10A is inserted through the opening 119 into the receiving space 118, which serves as the inner chamber of the bracket 116. The operator can visually view the acquisition kit 10A contained in the receiving space 118 through the opening 119.

[0073] The lower part of the bracket 116 has a connector support portion 136. Since there are two connectors 60 in the acquisition kit 10A, the bracket 116 has a first connector support portion 136a and a second connector support portion 136b as the connector support portions 136. The first connector support portion 136a and the second connector support portion 136b are generally cylindrical. The first connector 60a is entirely inserted into the first connector support portion 136a. The second connector 60b is entirely inserted into the second connector support portion 136b.

[0074] The upper part of the bracket 116 has a first slit 140, a second slit 142, and a third slit 144. A first exhaust pipe portion 36a is inserted into the first slit 140. The upper part of the first exhaust pipe portion 36a protrudes from the first slit 140 toward the top of the bracket 116. A first exhaust stack 42a is installed on this upper part. A second exhaust pipe portion 36b is inserted into the second slit 142. The upper part of the second exhaust pipe portion 36b protrudes from the second slit 142 toward the top of the bracket 116. A second exhaust stack 42b is installed on this upper part. The third slit 144 is located between the first slit 140 and the second slit 142. The middle portion 12m of the inflow pipe 12 is inserted into the third slit 144. When the collection kit 10A is accommodated in the receiving space 118, the upstream end 12u of the inflow pipe 12 is located above the third slit 144. As described above, interference between the first exhaust pipe section 36a, the second exhaust pipe section 36b, the inlet pipe 12, and the bracket 116 is avoided.

[0075] The lifting mechanism 150 includes a lifting operation section 152, a first displacement section 170, a first guide section 200, a second displacement section 210, a second guide section 230, and a gear mechanism 250. When the lifting operation section 152 is operated by the operator, the second displacement section 210, which includes a container holding section 220, moves in the vertical direction. Furthermore, the container holding section 220 is positioned below the kit holding section 110.

[0076] The lifting operation unit 152 has an operating lever 154 disposed on the front surface of the upper part of the two second support plates 106. A support shaft 158, which rotatably supports the operating lever 154, is supported on a guide bracket 160. The operating lever 154 is connected to the first movable plate 172 via two V-shaped arms 162, a connecting rod 164, and a plate nut 166.

[0077] The first displacement unit 170 includes the first movable disk 172 and the first drive plate 174 described above. The first movable disk 172 and the first drive plate 174 are raised and lowered integrally while being guided by the first guide unit 200. Hereinafter, the first movable disk 172, the first drive plate 174 and the first guide unit 200 will be described.

[0078] The first guide section 200 has two first guide rods 202 erected on the base 102. Each of the two first guide rods 202 passes through insertion holes formed at the left and right ends of the first movable disk 172, respectively. The upper part of each of the two first guide rods 202 protrudes upward from the cylindrical portion 204b of the first flanged collar 204 provided on the upper surface of the first movable disk 172. A first stop portion 206 is provided at the upper end of each of the two first guide rods 202. The upper surface of the large-diameter flange portion 204a of the first flanged collar 204 abuts against the lower surface of the first movable disk 172.

[0079] The first guide rod 202 passes through the interior of the first return spring 208. The lower end of the first return spring 208 abuts against the upper surface of the cylindrical portion 204b of the first flanged collar 204. The upper end of the first return spring 208 abuts against the lower surface of the first stop portion 206. The first return spring 208 applies a downward force to the first movable disk 172 via the first flanged collar 204.

[0080] The first drive plate 174 has a first vertical portion 175a extending in the vertical direction and a first horizontal portion 175b extending in the front-back direction. The first horizontal portion 175b is connected to the lower surface of the first movable disk 172. The first vertical portion 175a is connected to the front end of the first horizontal portion 175b in a downward manner.

[0081] The second displacement unit 210 will be described. The second displacement unit 210 includes a second movable disk 212. (As follows...) Figure 4 and Figure 7 As shown, the second movable disk 212 has a pedestal portion 213a extending along the width direction and an ear portion 213b protruding rearward from approximately the center of the pedestal portion 213a in the width direction.

[0082] like Figure 4 As shown, the container holding part 220 has a first container holder 220a and a second container holder 220b provided on the upper surface of the base part 213a. The first container holder 220a and the second container holder 220b are raised and lowered integrally with the second movable disk 212.

[0083] like Figure 7 As shown, a second drive plate 214 is provided on the upper surface of the ear portion 213b of the second movable disk 212. The second drive plate 214 has a second horizontal portion 215a extending in the front-rear direction and a second vertical portion 215b extending in the vertical direction. The second horizontal portion 215a is connected to the ear portion 213b when the lower surface of the second horizontal portion 215a abuts against the upper surface of the ear portion 213b. Therefore, the second movable disk 212 and the second drive plate 214 move up and down integrally.

[0084] The second guide portion 230 has two second guide rods 232 erected on the base 102. Each of the two second guide rods 232 passes through an insertion hole (not shown) formed at the left and right ends of the pedestal portion 213a. The upper part of each of the two second guide rods 232 protrudes upward from the second flanged collar 234. A second stop portion 236 is provided at the upper end of each of the two second guide rods 232.

[0085] The second guide rod 232 passes through the interior of the second return spring 238. The lower end of the second return spring 238 abuts against the upper surface of the second flanged collar 234. The upper end of the second return spring 238 abuts against the lower surface of the second stop portion 236. The second return spring 238 applies a downward force to the second movable disk 212 via the second flanged collar 234.

[0086] like Figure 7 As shown, the gear mechanism 250 has a first rack 252, a second rack 254, and a pinion 256 that meshes with the first rack 252 and the second rack 254. The first rack 252 is disposed on the lower front surface of the first longitudinal portion 175a of the first drive plate 174. The second rack 254 is disposed on the back side of the second longitudinal portion 215b of the second drive plate 214. The pinion 256 is sandwiched between the first rack 252 and the second rack 254. Furthermore, the pinion 256 is supported by a bearing 260 on an L-shaped support member 258 erected on the upper surface of the base 102.

[0087] (3) Data collection method Next, the collection method for dispensing platelet preparation M into the first sampling container 90a and the second sampling container 90b using the collection kit clamp 100 will be described.

[0088] The operator first as Figure 3 As shown, a medical bag 80 containing platelet preparation M is connected to an inflow tube 12. Specifically, the medical bag 80 has a supply tube 82. The operator engages the supply tube 82 with the upstream end 12u of the inflow tube 12. At this time, the supply tube 82 is engaged relative to the inflow tube 12 using a sterile engagement device, without contact with outside air.

[0089] Next, the operator moves the platelet preparation M into the first receiving chamber 30a and the second receiving chamber 30b. To achieve this movement, the operator opens the caps 46 of the first exhaust pipe 42a and the second exhaust pipe 42b. To open the caps 46, for example, the screw threaded between the caps 46 and the cylinder body 44 may be loosened. Alternatively, the caps 46 may be removed from the cylinder body 44. Furthermore, the caps 46 may be opened before the medical bag 80 is connected to the inflow tube 12.

[0090] The operator positions the medical bag 80 above the collection unit 14A. Platelet preparation M flows out of the medical bag 80 by gravity and flows through the supply tube 82 and the inflow tube 12 into the main connection 18a of the branch tube 16. A first secondary connection 18b and a second secondary connection 18c branch off from the main connection 18a. Therefore, the platelet preparation M is divided into a first branch moving from the main connection 18a through the first secondary connection 18b to the first inflow tube 32a, and a second branch moving from the main connection 18a through the second secondary connection 18c to the second inflow tube 32b.

[0091] The first branch flows into the first receiving chamber 30a through the first inlet pipe 32a. Therefore, the air stored in the first receiving chamber 30a is forced out by the first branch and discharged to the atmosphere through the first exhaust pipe 36a from the first exhaust stack 42a. Similarly, when the second branch flows into the second receiving chamber 30b through the second inlet pipe 32b, the air stored in the second receiving chamber 30b is discharged to the atmosphere through the second exhaust pipe 36b from the second exhaust stack 42b.

[0092] As platelet preparation M flows further into the first receiving chamber 30a and the second receiving chamber 30b, the remaining platelet preparation M comes into contact with the hydrophilic filters 48 of the first exhaust stack 42a and the second exhaust stack 42b, respectively. Thus, the remaining platelet preparation M is captured by the pores of the hydrophilic filters 48. As a result, the platelet preparation M is retained in the hydrophilic filters 48, which become blocked. Therefore, the platelet preparation M is prevented from flowing out of the first exhaust stack 42a and the second exhaust stack 42b through the hydrophilic filters 48. Therefore, the required amount of platelet preparation M is contained in the first receiving chamber 30a and the second receiving chamber 30b. The required amount is, for example, about 8 mL to 10 mL.

[0093] Then, the operator rotates the caps 46 of the first exhaust pipe 42a and the second exhaust pipe 42b to close them. The operator then uses a tube sealer (high-frequency sealer or ultrasonic sealer) to separate the medical bag 80 from the inlet tube 12. The tube sealer, while separating the inlet tube 12 from the supply tube 82 of the medical bag 80, seals the upstream end 12u of the inlet tube 12 by welding. The separation of the inlet tube 12 from the supply tube 82 is performed without exposing the internal flow path to external air.

[0094] The medical bag 80 separated from the inflow tube 12 is stored until the culture test is completed and then made available for use. Meanwhile, the collection kits 10A containing platelet preparation M, respectively contained in the first receiving chamber 30a and the second receiving chamber 30b, are moved into the purification table. The purification table is equipped with... Figure 4 The acquisition kit shown uses a clamp 100.

[0095] The operator inserts the collection kit 10A into the receiving space 118 via the opening 119 at the front end of the bracket 116. During this insertion, the operator inserts the first exhaust pipe section 36a, the second exhaust pipe section 36b, and the midstream section 12m of the inflow pipe 12 into the first slit 140, the second slit 142, and the third slit 144, respectively. The first exhaust pipe 42a and the second exhaust pipe 42b can be pre-installed in the first exhaust pipe section 36a and the second exhaust pipe section 36b before the collection kit 10A is inserted into the receiving space 118. Alternatively, the first exhaust pipe 42a and the second exhaust pipe 42b can also be installed in the first exhaust pipe section 36a and the second exhaust pipe section 36b after the collection kit 10A is inserted into the receiving space 118.

[0096] The operator closes the cover 120 and engages the fixing accessory 122 with the hook 124. When the cover 120 is closed, the first protrusion 134a crushes the first auxiliary connection 18b in the adapter pipe 302 or branch pipe 16, cutting off the connection between the inflow pipe 12 and the first inflow pipe 32a. Simultaneously, the second protrusion 134b crushes the second auxiliary connection 18c in the adapter pipe 302 or branch pipe 16, cutting off the connection between the inflow pipe 12 and the second inflow pipe 32b.

[0097] Alternatively, weld seals can be formed in the first sub-connection portion 18b and the second sub-connection portion 18c respectively, thereby cutting off the communication between the inflow pipe 12 and each of the first inflow pipe portion 32a and the second inflow pipe portion 32b. The weld seals are formed, for example, by welding the inner circumferential surfaces of the first sub-connection portion 18b and the second sub-connection portion 18c using an ultrasonic sealer or a high-frequency sealer. Alternatively, they can be formed using... Figure 10 The clamps 86 shown crush the first connecting part 18b and the second connecting part 18c respectively. With this structure, the cover 120 may not have the clamping part 130 (see reference). Figure 6 ).

[0098] In both cases, the first receiving chamber 30a and the second receiving chamber 30b are independent chambers. Therefore, platelet preparation M stored in the first receiving chamber 30a based on the first branch will not flow into the second inlet tube 32b or the second receiving chamber 30b. Similarly, platelet preparation M stored in the second receiving chamber 30b based on the second branch will not flow into the first inlet tube 32a or the first receiving chamber 30a. That is, movement of platelet preparation M between the first receiving chamber 30a and the second receiving chamber 30b is prevented.

[0099] In order to transfer platelet preparation M from collection kit 10A to the first sampling container 90a and the second sampling container 90b, the operator holds the peeling strip 72 after peeling it off from the first connector 60a and the second connector 60b. Figure 4One end of the operating lever 154 shown is rotated so that one end faces... Figure 4 Arrow A in the diagram points downwards. Therefore, as... Figure 8 As shown, connecting rod 164 descends.

[0100] As described above, the connecting rod 164 is connected to the first movable disk 172 via the plate nut 166, and the first drive plate 174 is connected to the first movable disk 172. Therefore, as Figure 8 As shown, as the connecting rod 164 descends, the first moving disk 172 and the first drive plate 174 descend together.

[0101] like Figure 7 As shown, a first rack 252 on the first longitudinal portion 175a of the first drive plate 174 meshes with a pinion 256, and the pinion 256 meshes with a second rack 254 on the second longitudinal portion 215b of the second drive plate 214. Therefore, when the first moving disk 172 and the first drive plate 174 descend, the pinion 256 is pushed downward by the first rack 252 and rotates. As a result, the second rack 254 is pushed upward by the pinion 256. Consequently, the second drive plate 214 and the second moving disk 212 connected to the second drive plate 214 rise together.

[0102] When the second movable disk 212 rises, the second return spring 238, which is disposed between the second flanged collar 234 and the second stop portion 236, is compressed axially. That is, the second movable disk 212 rises against the elastic force of the second return spring 238.

[0103] The container holding part 220 rises integrally with the second movable tray 212. As a result, the first sampling container 90a connects to the first connector 60a, and the second sampling container 90b connects to the second connector 60b. The needle 68 of the first connector 60a attaches to the plug 93 of the first sampling container 90a (see reference). Figure 4 and Figure 9 The needle 68 of the second connector 60b penetrates the plug 93 of the second sampling container 90b. The rubber cover 70 is pushed by the plug 93 and retracts in a manner that moves toward the cover member 66.

[0104] In this state, the operator rotates the cover 46 of each of the first exhaust pipe 42a and the second exhaust pipe 42b to open the cover 46. To open the cover 46, the operator can loosen the screw thread between the cover 46 and the pipe body 44 and remove the cover 46 from the pipe body 44.

[0105] With the cover 46 in the open position, air flows into the cylinder body 44. A portion of the air, while encountering resistance from the hydrophilic filter 48, flows into the first receiving chamber 30a and the second receiving chamber 30b via the first exhaust pipe 36a and the second exhaust pipe 36b, respectively. The resistance from the hydrophilic filter 48 suppresses the amount of air flowing into the first receiving chamber 30a and the second receiving chamber 30b.

[0106] Pressure is applied to the platelet preparation M contained in the first receiving chamber 30a and the second receiving chamber 30b respectively through atmospheric pressure. In the first receiving chamber 30a, pressure acts from the upper first exhaust pipe 36a toward the lower first outflow pipe 34a. Additionally, the first sampling container 90a is under negative pressure. Therefore, the platelet preparation M in the first receiving chamber 30a moves toward the first sampling container 90a via the first outflow pipe 34a. As a result, as... Figure 9 As shown, the first sample MS1 was collected into the first sampling container 90a.

[0107] The operator can visually confirm the inflow rate of the first sample MS1 by observing the scale 91 set on the first sampling container 90a. When the inflow rate of the first sample MS1 reaches the predetermined amount, the operator closes the cover 46 of the first exhaust stack 42a. Thus, the movement of platelet preparation M from the first receiving chamber 30a to the first sampling container 90a ends.

[0108] The platelet preparation M in the second receiving chamber 30b was also transferred to the second sampling container 90b. As a result, the second sample MS2 was collected into the second sampling container 90b. Furthermore, the collection of the second sample MS2 can be performed before or after the collection of the first sample MS1, or simultaneously with the collection of the first sample MS1.

[0109] Next, the operator rotates lever 154 to return to the starting position. Figure 4 The position is shown. Consequently, the second return spring 238 extends elastically. Simultaneously, the second moving disk 212 is exerted downward force via the second return spring 238 and via the second flanged collar 234. As a result, the second moving disk 212 and the container holding part 220 descend as a single unit. As the container holding part 220 descends, the first sampling container 90a is detached from the first connector 60a, and the second sampling container 90b is detached from the second connector 60b. Through the above steps, the collection (sampling) of platelet preparation M using the collection kit 10A is completed.

[0110] Following the descent of the second moving disk 212, in the opposite direction, the second rack 254 pushes the pinion 256 upward, and the pinion 256 pushes the first rack 252 upward. As a result, the first drive plate 174 and the first moving disk 172 rise, returning to their original positions. Figure 4 The location shown.

[0111] Next, samples MS1 (first sample) and MS2 (second sample) are subjected to culture tests. Specifically, sample MS1 in the first sampling container 90a is used for anaerobic culture, for example, to observe whether anaerobic bacteria proliferate. Sample MS2 in the second sampling container 90b is used for aerobic culture, for example, to observe whether aerobic bacteria proliferate. In both tests, the first sampling container 90a and the second sampling container 90b are used as culture bottles. If samples MS1 (first sample) and MS2 (second sample) pass the culture test, the platelet preparation M in the medical bag 80, which serves as the collection source for samples MS1 (first sample) and MS2 (second sample), is deemed qualified. The qualified product is used for patient treatment (blood transfusion, etc.).

[0112] The sample collection kit clamp 100 shown in the figure includes a lifting mechanism 150 for raising and lowering the container holding part 220. Alternatively, the sample collection kit clamp 100 may also include a lifting mechanism for raising and lowering the kit holding part 110. In this configuration, the container holding part 220 is positioned and fixed to the base 102.

[0113] The acquisition kit 10A of the first embodiment has the following effects.

[0114] Used to Figure 3 The collection kit 10A, which collects the sample (platelet preparation M) contained in the medical bag 80 shown, from multiple sampling containers 90 (first sampling container 90a and second sampling container 90b), includes an inflow tube 12 and a collection component 14A. The medical bag 80 is connected to the inflow tube 12. The collection component 14A is connected downstream of the inflow tube 12.

[0115] The collection component 14A has a plurality of receiving portions 22 and a plurality of receiving chambers 30 formed inside the plurality of receiving portions 22 and accommodating platelet preparation M. The collection kit 10A has a plurality of outflow tubes 34 and at least one venting portion 40.

[0116] Multiple outflow tubes 34 are connected to multiple receiving chambers 30, and platelet preparation M is transferred from the multiple receiving sections 22 toward multiple sampling containers 90 respectively. At least one exhaust section 40 exhausts the air inside the multiple receiving chambers 30 to the outside of the collection unit 14A respectively.

[0117] In the above structure, the collection component 14A is made of a non-flexible material. Therefore, the collection component 14A does not substantially deform when the platelet preparation M flows into each receiving chamber 30 and when the platelet preparation M flows out of each receiving chamber 30 into the sampling container 90. That is, the collection component 14A has the property of maintaining its initial shape (shape-conserving property). Therefore, each receiving portion 22 also has shape-conserving property.

[0118] Therefore, when platelet preparation M flows into each receiving chamber 30, deformation of each receiving section 22 can be suppressed. Thus, the amount of platelet preparation M transferred from the medical bag 80 to each receiving chamber 30 becomes approximately the same. That is, the amount of platelet preparation M contained in each receiving chamber 30 is fixed. Therefore, the sample amount of platelet preparation M collected in each sampling container 90 is stable.

[0119] The collecting component 14A has a plurality of inflow pipe sections 32 provided in each of the plurality of receiving sections 22 and connected to each of the plurality of receiving chambers 30. The inflow pipe 12 is connected to the inflow pipe section 32 via a branch pipe 16 (or branch pipe 17) connected to the downstream end 12d of the inflow pipe 12.

[0120] Based on this structure, platelet preparation M can be simultaneously dispensed into multiple receiving chambers 30. Therefore, the sample volume of platelet preparation M collected from the sampling container 90 is more stable.

[0121] Since the inflow pipe 32 is part of the acquisition component 14A, it is non-flexible. Therefore, it is easy to connect the branch pipe 16 (or branch pipe 17) to the inflow pipe 32.

[0122] The collecting component 14A has a pipe protection section 20 that covers the inflow pipe 12.

[0123] Because the inflow tube 12 is surrounded by the tube protection section 20, it is prevented from being accidentally crushed. As a result, blockage of the inflow tube 12 due to crushing is avoided. Therefore, platelet preparation M can be easily transferred from the medical bag 80 to each receiving chamber.

[0124] The pipe protection section 20 is integrated with multiple receiving sections 22.

[0125] In this case, a collection component 14A can be manufactured that integrates the tube protection section 20 and the multiple receiving sections 22. Therefore, compared to the case where the tube protection section 20 and the multiple receiving sections 22 are manufactured separately and then connected to the tube protection section 20, the collection component 14A can be constructed more efficiently.

[0126] The material of the collecting component 14A is resin. Other typical examples of resins include polycarbonate (PC), polypropylene (PP), polystyrene (PS), polyethylene terephthalate (PET), ethylene glycol-modified polyethylene terephthalate (PETG), and polyvinyl chloride (PVC).

[0127] Because resin is lightweight, the acquisition kit 10A can be made lightweight. Moreover, because resin is rigid, it is easy to construct a non-flexible acquisition component 14A.

[0128] The resin is transparent or translucent.

[0129] Based on this structure, the amount of platelet preparation M contained in the interior (reception chamber 30) of the multiple receiving parts 22 can be easily determined.

[0130] The exhaust section 40 has an exhaust pipe 42. The exhaust pipe 42 has a pipe body 44 with an opening 50 and a cover 46 that allows the opening 50 of the pipe body 44 to be opened and closed freely.

[0131] When transferring platelet preparation M from medical bag 80 to each receiving chamber 30, by opening the lid 46, air inside each receiving chamber 30 can be discharged to the outside of the collection unit 14A through the opening 50. After the transfer of platelet preparation M from medical bag 80 to each receiving chamber 30 is completed, by closing the lid 46, the platelet preparation M can be kept contained in each receiving chamber 30.

[0132] The exhaust stack 42 has a hydrophilic filter 48.

[0133] The hydrophilic filter 48 allows air to pass through before being wetted by the liquid platelet preparation M, and inhibits air passage after being wetted by the platelet preparation M. Therefore, even after the platelet preparation M overflows from each containment chamber 30 and wets the hydrophilic filter 48, airflow into each containment chamber 30 is inhibited, even if the cover 46 is opened and air is introduced through the opening 50. Therefore, the platelet preparation M transferred to the sampling container 90 can be used as a sample for anaerobic culture experiments.

[0134] The sampling kit 10A has a connector 60 that connects downstream of the outflow tube 34 and can be connected to multiple sampling containers 90. In the example shown, the number of connectors 60 is two (or more), but the number of connectors 60 can also be one. In other words, the sampling kit 10A has at least one connector 60.

[0135] The receiving section 22 and the sampling container 90 can be easily connected via the outflow tube 34 through the connector 60. Furthermore, since the sampling kit 10A has the connector 60 before use, the operator is spared the effort of connecting the connector 60 to the outflow tube 34 one by one when using the sampling kit 10A. As a result, sampling operations can be performed efficiently.

[0136] (4) Other implementation methods Next, refer to Figures 10-15 The acquisition kits 10B of the second embodiment to 10G of the seventh embodiment will be described. It should be noted that, regarding... Figures 1-9Components that are identical in the diagram are labeled with the same reference numerals, and detailed descriptions are omitted. The reference numerals for the acquisition components differ in embodiments 2 through 7, but all acquisition components are made of the same non-flexible material as in embodiment 1.

[0137] Figure 10 This is a schematic front view of the acquisition kit 10B according to the second embodiment. The acquisition kit 10B includes an acquisition component 14B. The acquisition component 14B has a first receiving portion 22a and a second receiving portion 22b. The inner chamber of the first receiving portion 22a is a first receiving chamber 30a, and the inner chamber of the second receiving portion 22b is a second receiving chamber 30b. The acquisition component 14B further includes a first inflow pipe portion 32a and a second inflow pipe portion 32b, a first outflow pipe portion 34a and a second outflow pipe portion 34b, a first exhaust pipe portion 36a and a second exhaust pipe portion 36b.

[0138] The first inlet pipe 32a is located above the first receiving portion 22a on the right side, towards the second receiving portion 22b. The first exhaust pipe 36a is located above the first receiving portion 22a on the left side, separated from the second receiving portion 22b. The first exhaust pipe 36a, together with the first exhaust cylinder 42a, constitutes the first exhaust portion 40a. The first outlet pipe 34a is located at the lower part of the first receiving portion 22a.

[0139] The second inlet pipe 32b is located on the upper part of the second receiving part 22b, towards the left of the first receiving part 22a. The second outlet pipe 36b is located on the upper part of the second receiving part 22b, separated from the first receiving part 22a on the right. The second outlet pipe 36b and the second outlet cylinder 42b together constitute the second outlet part 40b. The second outlet pipe 34b is located on the lower part of the second receiving part 22b.

[0140] The downstream end 12d of the inflow pipe 12 is connected to the main connection portion 18a of the branch pipe 16. The first inflow pipe portion 32a and the second inflow pipe portion 32b are connected to the first auxiliary connection portion 18b and the second auxiliary connection portion 18c of the branch pipe 16 via the adapter pipe 302, respectively. In this way, the inflow pipe 12 is connected to the first inflow pipe portion 32a and the second inflow pipe portion 32b above the first receiving portion 22a and the second receiving portion 22b via the branch pipe 16.

[0141] A first outflow port 300a is connected to a first outflow tube section 34a, and a second outflow port 300b is connected to a second outflow tube section 34b. The first outflow port 300a has a breakable plug (not shown) inside. In its initial state, the plug seals the first outflow port 300a. When transferring platelet preparation M from the first receiving chamber 30a to the first sampling container 90a, the plug breaks by being bent. Thus, the first outflow port 300a opens. Similarly, the second outflow port 300b opens as its internal plug (not shown) breaks.

[0142] The first outlet tube 34a is connected to the first connector 310a via the first outlet port 300a. The first connector 310a has a receiving tube 312 capable of accommodating the head of the first sampling container 90a, a connecting tube 314 located at the upper end of the receiving tube 312, a tubular needle 316 disposed inside the receiving tube 312, and a rubber cover 318 covering the needle 316. The receiving tube 312 has a cap 320 that can be opened and closed. Alternatively, a peeling tab 72 (see reference) may be used instead of the cap 320. Figure 1 and Figure 2 ).

[0143] The needle portion 316 inside the receiving cylinder 312 is connected to the connecting tube portion 314. In the first sampling container 90a (refer to...) Figure 9 When the head of the needle is inserted into the receiving tube 312, the needle 316 penetrates the plug 93 of the first sampling container 90a. Therefore, as the plug breaks and the first outflow port 300a is opened, the first sampling container 90a and the first receiving chamber 30a are connected via the connecting tube 314 and the needle 316.

[0144] When the needle 316 pierces the plug 93 of the first sampling container 90a, the rubber cover 318 is compressed by being pushed toward the collection member 14A. The needle 316 penetrates the compressed rubber cover 318. When the needle 316 is withdrawn from the plug 93 of the first sampling container 90a, the rubber cover 318 stretches with elastic restoring force and covers the needle 316 again.

[0145] The second connector 310b has the same structure as the first connector 310a. When the needle 316 of the second connector 310b penetrates the plug 93 of the second sampling container 90b and the plug breaks and the second outflow port 300b is opened, the second sampling container 90b is connected to the second receiving chamber 30b.

[0146] Alternatively, in the initial state of the acquisition kit 10B, the first connector 310a and the second connector 310b are not installed on the acquisition kit 10B. In this case, when using the acquisition kit 10B, the first connector 310a and the second connector 310b are connected to the acquisition kit 10B.

[0147] In this structure, the first protruding part 134a and the second protruding part 134b (refer to...) Figure 6 They respectively abut against the first connecting part 18b and the second connecting part 18c. Or, as... Figure 10 As shown, clips 86 can also be installed on the first sub-connection portion 18b and the second sub-connection portion 18c. In this state, platelet preparation M is transferred from the first receiving chamber 30a and the second receiving chamber 30b to the first sampling container 90a and the second sampling container 90b, respectively, in the same manner as in the first embodiment.

[0148] Figure 11 This is a schematic front view of the acquisition kit 10C according to the third embodiment. The acquisition kit 10C includes an acquisition component 14C. The acquisition component 14C has a first receiving portion 22a and a second receiving portion 22b. The acquisition component 14C further includes a first inflow pipe portion 32a and a second inflow pipe portion 32b, a first outflow pipe portion 34a and a second outflow pipe portion 34b, and a collection exhaust pipe portion 38. That is, the acquisition kit 10C has an exhaust portion 40. Furthermore, the acquisition kit 10C can be connected to two connectors 310 (first connector 310a and second connector 310b) that are independent of the acquisition kit 10C.

[0149] The first inflow pipe section 32a is located on the upper part of the first receiving section 22a, at the left portion away from the second receiving section 22b. The second inflow pipe section 32b is located on the upper part of the second receiving section 22b, at the right portion away from the first receiving section 22a. The downstream end 12d of the inflow pipe 12 is connected to the first receiving chamber 30a and the second receiving chamber 30b via the branch pipe 16, similar to the second embodiment.

[0150] The exhaust pipe section 38 has a first branch 39a located in the first receiving section 22a, a second branch 39b located in the second receiving section 22b, and a merging section 39c where the first branch 39a and the second branch 39b merge. The first branch 39a is located in the upper part of the first receiving section 22a, towards the right side of the second receiving section 22b. The second branch 39b is located in the upper part of the second receiving section 22b, towards the left side of the first receiving section 22a. An exhaust pipe 42 is provided in the merging section 39c. A first outlet pipe section 34a is located in the lower part of the first receiving section 22a.

[0151] A first outflow pipe section 34a is located at the lower part of the first receiving section 22a. A first connector 310a is connected to the first outflow pipe section 34a via a first outflow port 300a. A second outflow pipe section 34b is located at the lower part of the second receiving section 22b. A second connector 310b is connected to the second outflow pipe section 34b via a second outflow port 300b.

[0152] In this structure, when the platelet preparation M flows into the first receiving chamber 30a and the second receiving chamber 30b, the air in the first receiving chamber 30a, after flowing through the first branch 39a and the confluence section 39c, is discharged to the atmosphere via the exhaust pipe 42. The air in the second receiving chamber 30b, after flowing through the second branch 39b and the confluence section 39c, is discharged to the atmosphere via the exhaust pipe 42.

[0153] Subsequently, similar to the second embodiment, platelet preparation M is transferred to the first sampling container 90a installed in the first connector 310a, and platelet preparation M is transferred to the second sampling container 90b installed in the second connector 310b.

[0154] Figure 12 This is a schematic front view of the acquisition kit 10D according to the fourth embodiment. The acquisition kit 10D includes an acquisition component 14D. The acquisition component 14D has a first receiving portion 22a, a second receiving portion 22b, and a pipe protection portion 20. The inner chamber of the first receiving portion 22a is a first receiving chamber 30a, and the inner chamber of the second receiving portion 22b is a second receiving chamber 30b. The acquisition component 14D has a first inlet / outlet pipe 35a that serves as both the first inlet pipe 32a and the first outlet pipe 34a, and a second inlet / outlet pipe 35b that serves as both the second inlet pipe 32b and the second outlet pipe 34b. The acquisition component 14D further includes a first exhaust pipe 36a and a second exhaust pipe 36b.

[0155] The midstream portion 12m of the inflow pipe 12 passes through the pipe protection portion 20. A branch pipe 17 is provided at the downstream end 12d of the inflow pipe 12. The branch pipe 17 has a main connection portion 18a, a first auxiliary connection portion 18b, a second auxiliary connection portion 18c, and a connector connection portion 18d. The downstream end 12d is connected to the main connection portion 18a. The first inlet / outlet pipe portion 35a and the second inlet / outlet pipe portion 35b are connected to the first auxiliary connection portion 18b and the second auxiliary connection portion 18c, respectively. A connector 310 is connected to the connector connection portion 18d via the outlet port 300. That is, a connector 310, which is an independent entity relative to the collection component 14D, can be connected to the collection kit 10D.

[0156] In this structure, platelet preparation M flows into the first receiving chamber 30a and the second receiving chamber 30b via the first inlet / outlet tube 35a and the second inlet / outlet tube 35b. Then, when transferring platelet preparation M from the first receiving chamber 30a to a sampling container (not shown) mounted on the connector 310, the operator, for example, uses clamp 86 to clamp the upstream end 12u of the inlet tube 12 and the second auxiliary connection 18c. Therefore, only the platelet preparation M in the first receiving chamber 30a flows into the sampling container via the first inlet / outlet tube 35a, the first auxiliary connection 18b, and the outlet port 300.

[0157] After a predetermined amount of platelet preparation M is transferred to the sampling container, the operator removes the sampling container from the connector 310. Next, the operator installs other sampling containers (not shown) onto the connector 310. Alternatively, the operator may clamp the first sub-connector 18b using clamp 86. The clamp 86 installed on the second sub-connector 18c can be removed or left installed. In either case, only the platelet preparation M in the second receiving chamber 30b flows into the sampling container via the second inlet / outlet tube 35b, the second sub-connector 18c, and the outlet port 300. If the collection kit 10D has a receiving chamber 30 in addition to the first receiving chamber 30a and the second receiving chamber 30b, the above operation is repeated. As described above, platelet preparation M can be dispensed into multiple sampling containers.

[0158] Figure 13 This is a schematic front view of the data collection kit 10E according to the fifth embodiment. The data collection kit 10E includes a data collection component 14E. The data collection component 14E has a first receiving portion 22a, a second receiving portion 22b, and a pipe protection portion 20. The data collection component 14E further has a first inlet / outlet pipe portion 35a, a second inlet / outlet pipe portion 35b, and a collection exhaust pipe portion 38. A branch pipe 17 is provided at the downstream end 12d of the inlet pipe 12. That is, the data collection kit 10E has an exhaust portion 40. Furthermore, the data collection kit 10E can be connected to a connector 310 that is an independent entity relative to the data collection component 14E.

[0159] Similar to the fourth embodiment, in this structure, the platelet preparation M flows into the first receiving chamber 30a and the second receiving chamber 30b via the first inlet / outlet pipe 35a and the second inlet / outlet pipe 35b. During this flow, the air in the first receiving chamber 30a is discharged to the atmosphere via the exhaust pipe 42 after passing through the first branch 39a and the confluence section 39c. The air in the second receiving chamber 30b is discharged to the atmosphere via the exhaust pipe 42 after passing through the second branch 39b and the confluence section 39c.

[0160] Then, similarly to the fourth embodiment, the platelet preparation M contained in each of the first and second receiving chambers 30a and 30b is transferred to a sampling container (not shown).

[0161] In the acquisition kit 10D (reference) Figure 12 ) and Acquisition Kit 10E (refer to Figure 13 In this design, the first inlet / outlet pipe 35a also serves as the first inlet pipe 32a and the first outlet pipe 34a, and the second inlet / outlet pipe 35b also serves as the second inlet pipe 32b and the second outlet pipe 34b. Therefore, the structure of the acquisition components 14D and 14E and the acquisition kits 10D and 10E can be simplified.

[0162] Figure 14This is a schematic front view of the acquisition kit 10F according to the sixth embodiment. The acquisition kit 10F includes an acquisition component 14F. The acquisition component 14F has a first receiving portion 22a and a second receiving portion 22b. The acquisition component 14F further includes a first inflow pipe portion 32a and a second inflow pipe portion 32b, a first outflow pipe portion 34a and a second outflow pipe portion 34b, a first exhaust pipe portion 36a and a second exhaust pipe portion 36b. That is, the acquisition kit 10F has two exhaust portions 40 (a first exhaust portion 40a and a second exhaust portion 40b).

[0163] The acquisition kit 10F includes a confluence pipe 304. The confluence pipe 304 has a first branch 305b, a second branch 305c, and a confluence section 305a. The first outflow pipe 34a is connected to the first branch 305b via an adapter pipe 302. The second outflow pipe 34b is connected to the second branch 305c via another adapter pipe 302. A connector 310 is connected to the confluence section 305a via an outflow port 300. As described above, a connector 310, which is independent of the acquisition component 14F, can be connected to the acquisition component 14F.

[0164] In the collection kit 10F, similarly to the collection kit 10B of the second embodiment, platelet preparation M flows in from the top into each of the first receiving chamber 30a and the second receiving chamber 30b. Then, similarly to the fourth and fifth embodiments, the platelet preparation M contained in each of the first receiving chamber 30a and the second receiving chamber 30b is transferred to a sampling container (not shown).

[0165] Figure 15 This is a schematic front view of the acquisition kit 10G according to the seventh embodiment. The acquisition kit 10G includes an acquisition component 14G. The acquisition component 14G has a first receiving portion 22a and a second receiving portion 22b. The acquisition component 14G further includes a first inflow pipe portion 32a and a second inflow pipe portion 32b, a first outflow pipe portion 34a and a second outflow pipe portion 34b, and a collection exhaust pipe portion 38. That is, the acquisition kit 10G has an exhaust portion 40. And, similarly to the sixth embodiment, a connector 310, which is an independent entity relative to the acquisition component 14G, can be connected to the acquisition component 14G.

[0166] In the collection kit 10G, similarly to the collection kit 10C of the third embodiment, platelet preparation M flows in from the top into each of the first receiving chamber 30a and the second receiving chamber 30b. During this inflow, air in the first receiving chamber 30a is discharged to the atmosphere via the exhaust pipe 42 after flowing through the first branch 39a and the confluence section 39c. Air in the second receiving chamber 30b is discharged to the atmosphere via the exhaust pipe 42 after flowing through the second branch 39b and the confluence section 39c.

[0167] Then, similarly to embodiments 4 to 6, the platelet preparation M contained in each of the first and second receiving chambers 30a and 30b is transferred to a sampling container (not shown).

[0168] In the acquisition kit 10F (see reference) Figure 14 ) and 10G acquisition kit (refer to) Figure 15 In this assembly, a confluence pipe 304 is connected downstream of the first outflow pipe section 34a and the second outflow pipe section 34b, and a connector 310 is connected to the confluence section 305a of the confluence pipe 304. This allows for easy connection of a single connector 310 to multiple outflow pipe sections 34. Since there is only one connector 310, the structure of the acquisition kits 10F and 10G can be simplified.

[0169] In embodiments 2 to 7, a configuration is illustrated where the connector 310 connecting the acquisition kits 10B to 10G is a separate entity from the acquisition components 14B to 14G. However, the acquisition kits 10B to 10G can also be connected to the acquisition kit 10A (see...). Figure 1 and Figure 2 Similarly, it integrates the acquisition components 14B~14G and the connector 310.

[0170] As understood above, the acquisition kit is not limited to Figure 1 and Figure 2 The collection kit 10A is shown. It should be noted that when transferring platelet preparation M from the first receiving chamber 30a and the second receiving chamber 30b of each of the collection kits 10B to 10G to the first sampling container 90a and the second sampling container 90b respectively, it is possible to use... Figure 4 and Figure 8 The acquisition kit clamp 100 shown is constructed in the same manner as the acquisition kit clamp. In particular, the kit holding part 110 adopts a bracket 116 with a shape corresponding to the shape of the acquisition kits 10B to 10G.

[0171] The acquisition kits 10B of the second embodiment to 10G of the seventh embodiment achieve the same effect as the acquisition kit 10A of the first embodiment.

[0172] 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.
