Description

  The present invention relates to a blood bag for testing and a blood collection device having the same.

  Usually, in order to collect blood, a blood collection device for collecting blood in a blood bag (blood collection bag) from a blood collection needle through a tube is used. As this blood collection device, for example, a blood collection device (blood collection device) described in Patent Document 1 is known.

  The blood collection instrument described in Patent Document 1 includes a blood collection needle, a blood bag that stores blood collected through the blood collection needle, a blood collection tube that connects the blood collection needle and the blood bag, and a middle portion of the blood collection tube. It has a branched branch tube, an initial blood bag (test blood bag) communicating with the blood collection tube via the branch tube, and a sampling port (blood sampling port) connected to the lower end of the initial blood bag. In this blood collection device, before collecting blood from a donor (donor) into a blood collection bag, that is, before performing this blood collection, an initial flow of blood collected from the donor (initial blood) is collected in an initial blood bag ( Storage). The collected initial blood is collected in several blood collection tubes and used for various tests.

  In such a blood collection device, when the primary blood is collected in the primary blood bag, the air that was present in the blood collection tube and the branch tube through which the primary blood has passed gathers in the primary blood bag, so this air is When the blood collection tube is connected to the sampling port and the primary blood in the primary blood bag is collected, the sampling operation is performed with the sampling port facing downward so as not to enter the blood collection tube. For this reason, since it is necessary to perform a sampling operation by squatting, an improvement in operability is desired by an operator (collector).

  Therefore, in the blood collection instrument described in Patent Document 1, an extension tube connected to the sampling port and extending to the end portion in the initial blood bag is provided, and the sampling port is lifted to move the upper and lower sides of the initial blood bag. Even if the initial blood is collected in the blood collection tube in the inverted state, air does not enter the sampling port from the tip of the extension tube. Thereby, the worker does not have to perform the sampling operation by squatting.

  However, since the extension tube is relatively long and the air originally contained in the extension tube enters the blood collection tube during the sampling operation, the required amount (planned amount) is required for the first (first) blood collection tube. ) Could not be collected.

And a connecting member (holding means) 41 for connecting the two. Due to the action of the connecting member 41, the holder 82 is lifted and held together with the bag body 21 on the opening 822 side. In this state, the opening 822 of the holder 82 is directed in a direction different from the vertically downward direction, that is, is substantially vertically upward or inclined so that the central axis 822a of the opening 822 forms an acute angle with respect to the vertical upward direction. The size of the acute angle is not particularly limited, but is preferably 0 to 45 °, for example.

  In the present embodiment, the connecting member 41 includes an engaging portion (ring) 411 provided to protrude from the edge portion of the lid 51 (blood collection port 71). The engaging portion 411 is C-shaped. The inner diameter of the engaging portion 411 is set to be approximately equal to or slightly smaller than the outer diameter of the tube 91. Thereby, the engaging part 411 is reliably engaged (fitted) with the outer peripheral part of the tube 91 in the second state of the lid 51. Therefore, the sampling port 71 is reliably prevented from returning (hanging) vertically downward, that is, the state of the sampling port 71 (initial blood bag 20) shown in FIG. 3 is reliably maintained.

  When the above-described reduced pressure blood collection tube 85 is connected to the sampling port 71 (holder 82), the sampling port 71 is fixed to the blood inlet 24 by the engaging portion 411, that is, the state shown in FIG. Thereby, since the opening 822 of the sampling port 71 faces upward, the working posture of the worker (collector) when collecting the first blood flow through the sampling port 71 becomes an easy posture. That is, the initial blood can be easily (easily) collected through the sampling port 71 without the operator bending over.

  In addition, the collection of initial blood to the reduced pressure blood collection tube 85 is usually performed a plurality of times (for example, four times). Since the state shown in FIG. 3 is maintained in the first blood bag 20 as described above, when the operator replaces the vacuum blood collection tube 85, the operator removes the hand from the sampling port 71 and performs the operation (exchange operation). Can be done. Further, since the opening 822 of the sampling port 71 remains facing upward, the exchanged (unused) decompression blood collection tube 85 is quickly connected to the sampling port 71, that is, the exchanged decompression blood collection tube 85 is replaced. First blood can be collected quickly.

  As shown in FIGS. 3 and 4, when the sampling port 71 is lifted upward, the lid 51 in the second state is disposed at a position closer to the tube 91 than the opening 822 of the holder 82. Although the installation position of the engaging part 411 with respect to such a lid 51 is not particularly limited, for example, in the present embodiment, as shown in FIG. 3 (also in FIG. 4), it is on the side opposite to the opening 822.

  Further, when the engaging portion 411 is engaged with the tube 91, the bag body 21 is in a posture in which the sampling port 71 side (the edge portion side where the sampling port 71 is provided) is directed vertically upward.

  The engaging portion 411 having such a configuration may be formed integrally with the lid body 51, or a member configured separately from the lid body 51 is connected (joined) to the lid body 51. ) Is also good.

  Now, as shown in FIG. 2, the first blood bag 20 has a partition part (wall part) 26 that partitions the storage part 23 (inside the bag body 21) of the bag body 21 into an upper part and a lower part. ing. The partition portion 26 is a member (means) that partitions the storage portion 23 into a blood storage region 231 that stores initial blood (blood) and an air storage region 232 that stores air. The blood storage area 231 is communicated. Regarding the positional relationship between the blood storage area 231 and the air storage area 232, the air storage area 232 is positioned on the upper side (blood inlet 24 side), and the blood storage area 231 is positioned on the lower side.

  The partition unit 26 partitions the storage unit 23 into a blood storage region 231 and an air storage region 232 when collecting the initial blood blood stored in the storage unit 23 from the sampling port 71 into the decompression blood collection tube 85. It only has to be.

  Moreover, the partition part 26 is formed by partially fusing the facing sheet materials of the bag main body 21 (thermal fusion, high frequency fusion, etc.), and has a rod shape (longitudinal shape) (long shape). I am doing. That is, the partition part 26 is comprised by the rod-shaped unit melt | fusion part, and is arrange | positioned on the right side in FIG. The partition portion 26 and the blood inflow port 24 are in close contact with each other or welded (joined). And the lower end of the blood inflow port 24 is being fixed to the bag main body 21 by this partition part 26 and the unit melt | fusion part 251 mentioned later.

  Further, the vicinity of the end portion 262 distal to the blood inlet 24 of the partition portion 26 in the storage portion 23 (one end side in the longitudinal direction of the partition portion 26 (right side in FIG. 2)), that is, the end portion 262 and the seal portion. A communication part (communication path) 27 that communicates the blood storage area 231 and the air storage area 232 is formed between them.

  Further, the partition portion 26 is inclined so that an end portion 262 on the distal side from the blood inlet port 24 is located vertically above the proximal end portion 263 from the blood inlet port 24. That is, the surface of the partition portion 26 on the blood storage region 231 side (lower side in FIG. 2) is positioned vertically above the communication passage 27 side (end portion 262 side) from the sampling port 71 side (end portion 263 side). So as to be inclined. As a result, when the initial blood flow is introduced from the blood inlet 24 into the storage portion 23, the air in the blood storage area 231 can be smoothly and reliably moved to the air storage area 232.

  Further, the partition portion 26 is bent or curved in the vertical upward direction in the vicinity of the distal end portion 262 from the blood inflow port 24.

  The partition 26 may not be bent or curved in the vicinity of the distal end 262 from the blood inlet 24.

  In addition, the partition unit 26 serves as an index of the collection amount (target collection amount) when collecting the first blood, and has a function as a mark indicating the target liquid level (target position of the liquid level) of the first blood. That is, the initial blood is collected in the storage unit 23 until the initial blood starts to flow into the air storage region 232 via the communication unit 27. As a result, the operator does not align the line of sight with the liquid level of the primary blood, and the liquid level of the primary blood reaches the partition part 26, and the primary blood begins to flow into the air storage region 232. It can be easily confirmed visually that an amount of initial blood has been collected. Thus, the operator can perform the confirmation work in an easy posture while standing without taking an unreasonable posture such as crouching.

  The sampling port 71 described above is provided at a position sufficiently (a considerable distance) away from the communication portion 27 of the bag body 21 and communicates with the blood storage region 231. In the present embodiment, the sampling port 71 is provided at the edge of the bag body 21 on the other end side in the longitudinal direction of the partition portion 26 (left side in FIG. 2). Here, the position sufficiently separated from the communication part 27 of the bag main body 21 is a position across the blood storage region 231 from the communication part 27 in the bag main body 21, that is, in the bag main body 21 from the communication part 27 to the bag. A position separated by a distance of 2/3 or more of the width W of the storage portion 23 (inside the bag body 21) of the main body 21, preferably a position separated by a distance of 3/4 or more of the width W, more preferably a width. It is a position separated by a distance of W or more.

  Further, the first blood bag 20 has a restricting means for restricting the bulge (the degree of bulge) of the bag main body 21 inside the seal portion 22 of the bag main body 21. This restricting means is composed of a fusion part 25 that is formed by partially fusing the opposing sheet materials of the bag body 21 (thermal fusion, high frequency fusion, etc.). Thereby, when collecting the first blood flow (blood) in the storage unit 23 (in the bag main body 21), the swelling state of the bag main body 21 can be made constant. ) Can be reliably collected (stored).

  In the fusion part 25, each part (each part) may be continuous or may be separated from each other, but in the present embodiment, the fusion part 25 is a plurality of parts provided apart from each other. The unit fusion part 251 is composed of a plurality of unit fusion parts 251.

  Each unit fusion part 251 (fusion part 25) is provided only in blood storage region 231. As a result, the blood storage area 231 and the air storage area 232 can be easily distinguished visually, and the swelling of the blood storage area 231 of the bag body 21 can be regulated to have a constant volume. It is possible to collect a first blood flow of a predetermined volume (a constant amount).

In the present embodiment, the unit fusion portions 251 are arranged in a matrix at regular intervals.
Further, the fusion part 25 is configured so that the volume (volume) of the blood storage region 231 is substantially equal to the target collection amount when the portion of the blood storage region 231 of the bag body 21 is swelled to the maximum. When the initial blood flow is collected until the liquid level reaches the partition portion 26 and the initial blood flow begins to flow into the air storage region 232, the volume of the blood storage region 231 is set to be substantially equal to the target collection amount. ing.

  Moreover, it is preferable that a target collection amount is about 20-30 mL, and about 25 mL is especially preferable. This makes it possible to collect (remove) the primary blood that may be contaminated with bacteria from the blood collected from the donor without excess or deficiency. As a result, contamination of the blood collected in the blood collection bag 10 with bacteria is suppressed, the safety of the blood product is improved, and good blood free from bacterial contamination that should be collected in the blood collection bag 10 is originally wasted. It is possible to prevent the blood from being collected in the first blood bag 20.

  In addition, various conditions such as the shape, size, orientation (direction), number, interval (pitch), arrangement (any of rules and irregularities), arrangement pattern, and the like of the unit fusion part 251 are not particularly limited, and are appropriately determined. Can be set.

  The shape of the unit fused portion 251 in plan view is a circle in the illustrated example, but there are many other shapes such as an ellipse, a semicircle, a semi-elliptical, a triangle, a quadrangle (for example, a rhombus), and the like. Examples include a rectangular shape, a linear shape (bar shape), a long shape such as a curved shape, and the like.

  Next, an example of the action of the blood collection device 1 (blood treatment method using the blood collection device 1) will be described.

  As shown in FIG. 2, when the initial blood flow (blood) is introduced from the blood inlet 24 into the storage portion 23 of the bag body 21, the air storage area 232 is positioned vertically above the blood storage area 231.

  As shown in FIGS. 1 and 2, in the initial blood bag 20, the lid 51 is in the first state, that is, in the closed state.

  Further, the clamp 95 is in an open state, and the tube 15 is closed (sealed) by the sealing member 93. As a result, when the blood collection needle 151 is punctured into the donor, blood from the tube 94 can sequentially pass through the first port 921 and the second port 922 of the branch connector 92 and flow into the tube 91.

  In addition, the blood collection bag 10 and the initial blood bag 20 of the blood collection device 1 are respectively installed at positions lower than the site where the blood collection needle 151 is punctured.

  Next, the cap 154 is removed from the blood collection needle 151 (see FIG. 1), the blood collection needle 151 is punctured into the donor's vein (blood vessel), and when it is confirmed that the blood collection needle 151 captures the vein, the hub 153 is attached to the donor's vein. For example, it is fixed with an adhesive tape in the vicinity of the puncture site. Similarly, the tube 97 (tube 94) is also preferably fixed with an adhesive tape near the puncture site.

  By such an operation, the primary blood (blood) flows into the tube 91 through the blood collection needle 151, the tube 94, and the branch connector 92, flows through the tube 91, and is introduced into the storage portion 23 of the initial blood bag 20. . In this case, since the flow path of the tube 15 is blocked by the sealing member 93 as described above, blood reliably flows from the tube 94 to the tube 91 via the branch connector 92.

  In addition, before the blood is introduced, air in the tubes 94 and 91 and the branch connector 92 is discharged from the tube 91 and collected in the initial blood bag 20. As a result, the pressure in the tubes 94 and 91 and the volume of the lumens of the tubes 94 and 91 can be kept substantially constant, and an excessive load can be prevented from being applied to the blood cells. It is possible to prevent hemolysis and the like from occurring. Further, blood does not enter and remain on the side of the sealing member 93 in the branch connector 92.

  When the liquid level of the primary blood in the storage part 23 of the primary blood bag 20 reaches the partition part 26 and the primary blood begins to flow into the air storage region 232, the clamp 95 is closed and the flow path of the tube 91 is closed. To do. In this manner, a predetermined amount (target amount) of blood is collected (collected) in the initial blood bag 20. Air is stored in the air storage region 232.

  By this initial blood collection operation, it is possible to collect (remove) primary blood that may be contaminated with bacteria from the blood collected from the donor, and thereby bacteria into the blood collected in the blood collection bag 10 described later. Is suppressed, and the safety of blood products is improved.

Next, blood collection (main blood collection) into the blood collection bag 10 is started.
In this case, the breaking portion 933 of the sealing member 93 is broken to separate the solid columnar portion 932, and the flow path in the sealing member 93 is opened. By this operation, the tube 97 communicates (opens) the flow path from the upstream side to the downstream side. Thereby, the collected blood flows through the tube 97 and is introduced into the blood storage part 13 of the blood collection bag 10.

In parallel with the collection of blood into the blood collection bag 10, the primary blood stored in the primary blood bag 20 is collected (sampled) into the vacuum blood collection tube 85.
The sampling may be performed after blood collection into the blood collection bag 10 is completed.

  In order to perform sampling, prior to the sampling, first, the lid 51 of the holder 82 is opened, that is, the second state is set. Next, as described above, the sampling port 71 is locked to the tube 91 by the engaging portion 411 as shown in FIG. As a result, the sampling port 71 has a posture in which the opening 822 faces vertically upward, and the bag body 21 has a posture in which the sampling port 71 side (the edge side on which the sampling port 71 is provided) faces vertically upward. It becomes. And the state by which the air was stored by the air storage area | region 232 is hold | maintained.

  As described above, the posture of the bag body 21 is different between when the initial blood is introduced from the blood inlet 24 into the storage unit 23 and when the initial blood stored in the storage unit 23 is collected (collected) from the sampling port 71. Different.

  Even if a very small amount of air (bubbles) is present in the blood in the blood storage region 231, the blood outlet 96 protrudes into the bag body 21, so that the air flows into the blood outlet 96. It is possible to prevent the air from being sucked into the vacuum blood collection tube 85 by moving vertically upward from the end face.

  Next, the decompression blood collection tube 85 is inserted into the locked sampling port 71 (holder 82) and pushed to the innermost part of the sampling port 71 (holder 82), and the hollow needle 84 is punctured into the rubber plug 87 and penetrated. Let As a result, the initial blood stored in the initial blood bag 20 flows through the blood outlet 96 and is sucked into the vacuum blood collection tube 85 and collected. In this case, the partition part 26 prevents the air in the air storage region 232 from moving to the blood storage region 231 and can prevent the air from entering the reduced pressure blood collection tube 85. In addition, since the sampling port 71 is in a state in which the opening 822 faces upward, the decompression blood collection tube 85 can be easily inserted into the sampling port 71 from above. After collection, the vacuum blood collection tube 85 is removed from the sampling port 71. Note that this operation is repeated when sampling the first blood flow into a plurality of reduced-pressure blood collection tubes 85. Thereafter, the engagement by the engaging portion 411 is released and the lid 51 is closed, that is, the first state is set again.

  In collecting blood into the blood collection bag 10, after collecting a predetermined amount of blood into the blood collection bag 10, the blood collection needle 151 is removed from the donor's blood vessel, and the tubes 91, 94, and 15 are melted with a tube sealer or the like as necessary. Seal by wearing. Thereafter, the initial blood bag 20 and the blood collection needle 151 are separated.

  Thereby, the blood collection bag 10 in which the collected blood from which the initial blood has been removed is stored is obtained.

  The blood stored (collected) in the blood collection bag 10 is passed through a leukocyte removal filter to separate white blood cells and platelets, the remaining blood components are collected in a collection bag, and the blood collection bag 10 and the white blood cell removal filter are separated. . Thereafter, the blood in the collection bag is centrifuged to separate the red blood cell layer and the plasma layer. After transferring the plasma to the plasma bag, the red blood cells in the bag containing the red blood cell storage solution are added to the concentrated red blood cells remaining in the collection bag. Add the stock solution and mix.

  On the other hand, the primary blood collected in the vacuum blood collection tube 85 is used for, for example, tests such as a biochemical test for serum and a nucleic acid amplification test for infectious disease viruses (for example, AIDS, hepatitis, etc.).

  As described above, according to the initial blood bag 20 and the blood collection device 1, when the initial blood stored in the storage portion 23 of the initial blood bag 20 is collected in the reduced pressure blood collection tube 85 via the sampling port 71, The unit 26 can prevent the air in the air storage area 232 from moving to the blood storage area 231. Thereby, since air does not enter into the decompression blood collection tube 85, a necessary amount of initial blood can be reliably collected. As a result, the primary blood can be used as test blood.

  In addition, the operator can easily and quickly collect the initial blood blood stored in the storage unit 23 into the reduced pressure blood collection tube 85 via the sampling port 71 in a posture in which the worker can easily work while standing. .

  In addition, when collecting the first blood in the storage part 23 of the first blood bag 20, the swelling of the bag body 21 can be made constant, and the partition 26 serves as an index of the target collection amount, and the target liquid for the first blood is collected. Since it has a function as a mark indicating the position, the operator can easily and surely collect a predetermined amount (target amount) of initial blood in the storage unit 23 in a posture that makes it easy to work while standing. it can.
