Definitions
- the present invention relates to a filter device.
- Patent Publication No. 5223006 describes a blood bag system and a centrifugal separation and transfer device (centrifuge).
- the blood bag system contains blood.
- the centrifuge centrifuges the blood contained in the blood bag system.
- the centrifugal separation results in the centrifugal separation of the blood.
- the centrifuged blood is used for transfusion.
- blood to be transfused does not contain white blood cells. Recently, there has been a demand for a filter device that can more effectively remove white blood cells.
- the present invention aims to solve the above-mentioned problems.
- One aspect of the present invention is a filter device that is attached to a centrifuge, the filter device comprising: a first space formed within a housing into which blood flows in via an inlet; a second space formed within the housing into which blood flows out via an outlet; a partition wall that separates the first space from the second space; a communication port that connects the first space to the second space; and a leukocyte removal filter that is disposed within the second space and removes leukocytes contained in the blood, the second space being located between the first space and the center of rotation of the centrifuge.
- the inlet may be located on one side of the first space in a first direction intersecting a centrifugal direction in which centrifugal force is applied, and the communication port may be located on the other side of the first space in the first direction.
- the outlet may be located on one side of the second space in the first direction, and the communication port may be located on the other side of the second space in the first direction.
- the first space may be provided with a guide wall that guides the blood flowing in through the inlet in a centrifugal direction, which is the direction in which centrifugal force is applied.
- the inlet and the communication port may be located on one side of the first space in a first direction that intersects with a centrifugal direction in which centrifugal force is applied.
- the communication port may be located on one side of the second space in the first direction, and the outlet may be located on the other side of the second space in the first direction.
- the first space may be provided with a curved wall, and the inlet and the communication port may be located between the center of rotation of the centrifuge and the curved wall.
- an inflow passage extending from the inlet to the first space and separated from the second space may be formed in the housing, and the inflow passage may extend along a centrifugal direction in which centrifugal force is applied.
- the present invention makes it possible to effectively remove white blood cells.
- FIG. 1 is a perspective view showing a centrifuge to which a filter device according to one embodiment is attached.
- FIG. 2 is a perspective view showing the filter device.
- FIG. 3 is a plan view showing the internal structure of the filter device.
- FIG. 4 is a plan view showing the internal structure of a filter device according to a modified example.
- FIG. 1 is a perspective view showing a centrifuge 50 to which a filter device 10 according to the present embodiment is attached.
- the filter device 10, an insert unit 60, and the centrifuge 50 are shown in Fig. 1.
- the centrifuge 50 is a machine that performs centrifugation on blood.
- the centrifuge 50 is equipped with a centrifugal drum 52.
- the centrifuge drum 52 is equipped with a central body 52a and multiple unit insertion portions 52b.
- the multiple unit insertion sections 52b are arranged to surround the central body 52a.
- An insert unit 60 can be inserted into each of the multiple unit insertion sections 52b. By inserting the insert unit 60 into the unit insertion section 52b, the insert unit 60 is attached to the centrifuge 50.
- the insert unit 60 houses a blood bag system (not shown).
- the blood bag system includes a blood bag that contains blood before it is centrifuged.
- the blood contained in this blood bag is, for example, whole blood, but it may also be a buffy coat as described in the above-mentioned Patent Publication No. 5223006.
- the buffy coat contains red blood cells, platelets, white blood cells, etc.
- the centrifuge 50 rotates the insert unit 60 inserted into the unit insertion section 52b around the central body 52a. More specifically, the centrifuge 50 rotates the insert unit 60 inserted into the unit insertion section 52b in the rotation direction DR around the rotation center line (center of rotation) LA shown in FIG. 1. This applies centrifugal force to the entire insert unit 60. This centrifugal force causes the blood to be centrifuged.
- the rotation center line LA is, for example, along the direction of gravity (the second direction D2 described below).
- the filter device 10 is attached to the insert unit 60.
- the filter device 10 is attached to the upper part of the insert unit 60, for example, but is not limited to this.
- the filter device 10 is attached to the insert unit 60, and is then attached to the centrifuge 50 via the insert unit 60.
- the above-mentioned centrifugal force is applied not only to the insert unit 60, but also to the filter device 10.
- the filter device 10 may also be attached directly to the centrifuge 50.
- FIG. 2 is a perspective view showing the filter device 10.
- the filter device 10 can be attached to the centrifuge 50.
- the configuration of the filter device 10 will be described on the assumption that the filter device 10 is attached to the centrifuge 50.
- the centrifugal direction DC, the centripetal direction DC-, the first direction D1, and the second direction D2 are shown in FIG. 2.
- the centrifugal direction DC is the direction of the centrifugal force applied to the filter device 10 by the centrifuge 50.
- the first direction D1 is the direction of the tangential velocity in the circular motion of the filter device 10 performed by the centrifuge 50.
- the first direction D1 is perpendicular (intersects) to the centrifugal direction DC.
- the second direction D2 is the direction of gravity.
- the centrifugal direction DC and the first direction D1 are perpendicular to the second direction D2.
- the centripetal direction DC- is the opposite direction to the centrifugal direction DC.
- the filter device 10 includes a housing 12.
- the housing 12 may be formed, for example, in a box shape.
- the thickness direction of the housing 12 coincides with the second direction D2.
- the housing 12 has an inlet portion 14 and an outlet portion 16.
- the inlet portion 14 has an inlet port 14a.
- the outlet portion 16 has an outlet port 16a.
- the inlet port 14a and the outlet port 16a are each an opening that connects the inside and outside of the housing 12.
- the inlet portion 14 and the outlet portion 16 shown in FIG. 2 protrude from the housing 12, but are not limited to this.
- the blood bag connected to the inlet 14 is a blood bag that already contains blood before it is centrifuged.
- the blood bag connected to the outlet 16 is a blood bag for containing blood (blood components) that has passed through the filter device 10.
- Figure 3 is a plan view showing the internal structure of the filter device 10.
- the housing 12 further includes an inflow passage 25, a first space 18, a second space 20, a partition wall 22, a leukocyte removal filter 24, and a communication port 28.
- the inflow passage 25, the first space 18, the second space 20, the partition wall 22, and the communication port 28 are provided within the housing 12.
- the leukocyte removal filter 24 is disposed in the second space 20.
- the first space 18 is located in the centrifugal direction DC with respect to the inflow passage 25 and the second space 20.
- the inflow passage 25 and the second space 20 are located between the first space 18 and the center of rotation LA ( Figure 1) of the centrifuge 50.
- the second space 20 is located in the first direction D1 with respect to the inflow passage 25.
- the partition 22 separates the first space 18 from the second space 20, and also separates the second space 20 from the inflow passage 25. More specifically, the partition 22 has a first wall portion 221 along the first direction D1 and a second wall portion 222 along the centrifugal direction DC. The first wall portion 221 separates the first space 18 from the second space 20. The second wall portion 222 separates the second space 20 from the inflow passage 25.
- the inflow flow path 25 is a flow path that reaches the first space 18 from the inlet 14a.
- the inflow flow path 25 extends along the centrifugal direction DC. Blood flows into the inflow flow path 25 via the inlet 14a.
- the inlet 14a is formed along the centrifugal direction DC. In this case, the centrifugal force applied by the centrifuge 50 causes the blood to flow smoothly through the inlet 14a and into the first space 18.
- the first space 18 has a first portion 181 and a second portion 182.
- the first portion 181 is located on one side of the center line C18.
- the second portion 182 is located on the other side of the center line C18.
- the center line C18 is an imaginary straight line that passes through the center of the first space 18 in the first direction D1 and is aligned with the centrifugal direction DC.
- the second portion 182 is located in the first direction D1 relative to the first portion 181.
- the first portion 181 of the first space 18 is connected to the inflow channel 25. Blood can flow along the inflow channel 25 into the first portion 181 of the first space 18 (FL1).
- the first space 18 is provided with a curved wall 26.
- the curved wall 26 is a part of the inner wall that defines the first space 18.
- the inlet flow passage 25 (inlet 14a) and the communication port 28 are located between the center of rotation LA ( Figure 1) of the centrifuge 50 and the curved wall 26.
- the curved wall 26 is curved to guide blood from the first portion 181 toward the second portion 182. This allows blood that has flowed into the first portion 181 via the inflow flow path 25 to flow along the curved wall 26 toward the second portion 182 without flowing back toward the inlet 14a (FL2, FL3).
- the blood that has flowed into the first space 18 is centrifuged by the centrifuge 50.
- the blood in the first space 18 forms a layer of supernatant liquid and a layer of sediment liquid.
- the layer of sediment liquid is located in the centrifugal direction DC relative to the layer of supernatant liquid.
- the main component of the sedimentation liquid is white blood cells.
- White blood cells are the main component of the sedimentation liquid because they are a relatively heavy blood component.
- white blood cells are a blood component that settles relatively easily, and therefore are the main component of the sedimentation liquid.
- the supernatant liquid contains blood components that are lighter than white blood cells.
- the supernatant liquid contains a large amount of platelets, etc.
- the white blood cells contained in the blood that has flowed into the first space 18 are collected on the centrifugal direction DC side of the first space 18 by the centrifugal force applied by the centrifuge 50 (FL2). Meanwhile, blood components other than the white blood cells are collected on the centripetal direction DC- side of the first space 18 (FL3).
- the communication opening 28 is an opening that communicates the first space 18 and the second space 20.
- the communication opening 28 is located between the first space 18 and the second space 20. As shown in FIG. 3, the second space 20 is located in the centripetal direction DC- with respect to the first space 18. Therefore, the communication opening 28 is located in the centripetal direction DC- with respect to the first space 18.
- the communication opening 28 is formed, for example, in the first wall portion 221 of the partition wall 22, but is not limited to this.
- the blood that has flowed into the first space 18 can flow into the second space 20 via the communication port 28 (FL4).
- blood components other than white blood cells are collected on the centripetal direction DC- side of the first space 18. Therefore, blood components other than white blood cells tend to flow into the second space 20 via the communication port 28. In other words, white blood cells do not easily flow into the second space 20.
- the inlet 14a (inlet flow passage 25) is connected to the first portion 181 of the first space 18.
- the communication port 28 is connected to the second portion 182 of the first space 18. In this way, blood flowing due to centrifugal force can be prevented from immediately flowing from the inlet 14a to the communication port 28. In other words, it is possible to prevent the blood flowing from the inlet 14a from reaching the communication port 28 before being separated into the sediment and supernatant liquid described above.
- the leukocyte removal filter 24 is disposed in the second space 20.
- the leukocyte removal filter 24 is equipped with a filter material for removing leukocytes from blood.
- the blood that flows into the second space 20 is filtered by the leukocyte removal filter 24.
- the leukocytes are removed by the leukocyte removal filter 24.
- the second space 20 is provided with an outflow section 16.
- the outflow section 16 is provided with an outlet 16a. Therefore, blood in the second space 20 can flow out of the housing 12 via the outlet 16a (FL5).
- the outlet 16a is located between the communication port 28 and the center of rotation LA (FIG. 1) of the centrifuge 50. In this way, it is possible to prevent white blood cells that have flowed into the second space 20 from reaching the outlet 16a. In other words, in order for blood that has flowed into the second space 20 to reach the outlet 16a, it must flow in the centripetal direction DC- from the communication port 28. As described above, when centrifugation is performed by the centrifuge 50, white blood cells are unlikely to flow in the centripetal direction DC-. By making the direction from the outlet 16a toward the communication port 28 the centrifugal direction DC as shown in FIG. 3, it is possible to prevent white blood cells from reaching the outlet 16a. This makes it possible to more suitably reduce the amount of white blood cells contained in the blood taken out from the outlet 16a.
- the second space 20 has a first portion 201 and a second portion 202.
- the first portion 201 is located on one side of the center line C20.
- the second portion 202 is located on the other side of the center line C20.
- the center line C20 is an imaginary straight line that passes through the center of the second space 20 in the first direction D1 and is aligned with the centrifugal direction DC.
- the second portion 202 is located in the first direction D1 relative to the first portion 201.
- the communication port 28 is connected to the second portion 202 of the second space 20.
- the outlet 16a is connected to the first portion 201 of the second space 20. In this way, a sufficiently long blood movement path can be secured within the leukocyte removal filter 24. This makes it possible to more reliably remove leukocytes using the leukocyte removal filter 24.
- the blood that flows into the first space 18 is centrifuged by the centrifuge 50. This reduces the amount of white blood cells contained in the blood that flows into the second space 20.
- the white blood cells remaining in the blood that flows into the second space 20 are removed by the white blood cell removal filter 24.
- FIG. 4 is a plan view showing the internal structure of a modified filter device 10 (10A).
- the first space 18 may be provided with a guide wall 32 that guides blood flowing in through the inlet 14a in the centrifugal direction DC.
- the guide wall 32 is located between the communication port 28 and the inlet 14a (inlet flow path 25) in the first direction D1.
- the guide wall 32 extends, for example, in the centrifugal direction DC and further in the first direction D1.
- the guide wall 32 prevents blood that has flowed into the first space 18 from immediately reaching the communication port 28 along the first direction D1 (FL6). In other words, blood that has flowed into the first space 18 from the inlet 14a cannot reach the communication port 28 unless it detours around the guide wall 32. This makes it possible to prevent blood that has not yet been centrifuged in the first space 18 from immediately reaching the communication port 28.
- the communication port 28 may be located in the first portion 181 of the first space 18.
- the guide wall 32 may prevent blood that has flowed into the first space 18 from immediately reaching the communication port 28 along the first direction D1.
- the communication port 28 located in the first portion 181 of the first space 18 can be connected to the first portion 201 of the second space 20. In such a case, it is preferable to position the outlet 16a in the second portion 202 of the second space 20. In this way, a sufficiently long blood movement path can be secured within the leukocyte removal filter 24. This makes it possible to more reliably remove leukocytes using the leukocyte removal filter 24.
- the present invention is not limited to the above disclosure, and various configurations may be adopted without departing from the gist of the present invention.
