Description

[Technical field]

[0001] The present disclosure relates to a fluid removal device. [Background technology]

[0002] For example, a technique for transplanting a transplant such as a cell sheet into a living body is known. Patent Document 1 describes a transport container used for transporting the transplant to an intensive care unit or the like where the transplant is performed. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] International Publication No. 2020 / 130015 Summary of the Invention [Problem to be solved by the invention]

[0004] The graft is transported to an intensive care unit or the like in a transport container as described in Patent Document 1 together with a liquid such as a preservative solution or a buffer solution. The liquid in the transport container is then removed, and the graft is taken out of the transport container. The graft taken out of the transport container is transferred onto a transplantation device used for transplantation, and is transplanted into a target site in a living body by the transplantation device.

[0005] If the liquid flows during the removal of the liquid from the transport container after transport, an external force is applied to the implant, which may cause unintended deformation or damage to the implant. In particular, when the implant is a thin, fragile sheet-like material, the influence of the above-mentioned liquid flow is significant.

[0014] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a liquid removal device according to the present disclosure will be illustrated and described with reference to the drawings, in which the same components are designated by the same reference numerals.

[0015] Fig. 1 is a diagram showing a liquid removal device 1 as one embodiment of the liquid removal device according to the present disclosure. As shown in Fig. 1, the liquid removal device 1 includes an annular main body 2. For ease of explanation, the direction along the central axis O of the main body 2 will be referred to as the "axial direction A". Furthermore, the direction around the central axis O of the main body 2 will be referred to as the "circumferential direction B". Furthermore, the radial direction of a circle centered on the central axis O of the main body 2 will be referred to as the "radial direction C".

[0016] The annular main body 2 defines a through hole 2a penetrating in the axial direction A. The main body 2 includes absorbents 3 and non-absorbents 4 arranged alternately in the circumferential direction B. As shown in FIG. 1, the main body 2 of this embodiment is composed of eight absorbents 3 and eight non-absorbents 4. The absorbents 3 may be a foam having open cells formed by foaming, for example, sponge, rubber, synthetic resin, etc. The non-absorbents 4 may be a non-foamed material such as solid resin without cavities, rubber, synthetic resin, etc.

[0017] 1, in the main body portion 2 of this embodiment, two absorbents 3 adjacent in the circumferential direction B are not in direct contact with each other, but a non-absorbent body 4 is interposed between them. In addition, in the main body portion 2 of this embodiment, two non-absorbents 4 adjacent in the circumferential direction B are not in direct contact with each other, but an absorbent body 3 is interposed between them. The absorbents 3 and non-absorbents 4 connected in the circumferential direction B are joined together, for example, by adhesion.

[0018] FIG. 2 is a cross-sectional view of the non-absorbent body 4. As shown in FIG. 2, the non-absorbent body 4 defines a liquid suction path 5 having a suction port 5a on one side 4a of the non-absorbent body 4 in the axial direction A. The suction port 5a of the liquid suction path 5 is an opening at one end of the liquid suction path 5, and the discharge port 5b, which is the opening at the other end of the liquid suction path 5, is formed on the other side 4b of the non-absorbent body 4 in the axial direction A. The liquid removal tool 1 of this embodiment is used so that the surface 4a of the non-absorbent body 4 on one side in the axial direction A where the suction port 5a of the liquid suction path 5 is formed faces downward in the vertical direction. In other words, the liquid removal tool 1 of this embodiment is used so that the surface 4b of the non-absorbent body 4 on the other side in the axial direction A where the discharge port 5b of the liquid suction path 5 is formed faces upward in the vertical direction. Therefore, in the following, for convenience of explanation, the surface 4a of the non-absorbent body 4 on one side in the axial direction A where the suction port 5a of the liquid suction path 5 is formed is described as the "lower surface 4a". Moreover, the surface 4b on the other side in the axial direction A of the non-absorbent body 4 on which the outlet 5b of the liquid suction path 5 is formed is referred to as the "upper surface 4b".

[0019] In the nonabsorbent 4 shown in Fig. 2, the suction port 5a of the liquid suction path 5 is formed at a position closer to the inner side surface 4c, which is the inner surface in the radial direction C of the nonabsorbent 4, than the discharge port 5b. In other words, in the nonabsorbent 4 shown in Fig. 2, the discharge port 5b of the liquid suction path 5 is formed at a position closer to the outer side surface 4d, which is the outer surface in the radial direction C of the nonabsorbent 4, than the suction port 5a. However, the positional relationship in the radial direction C of the suction port 5a and discharge port 5b of the liquid suction path 5 is not limited to the positional relationship shown in Fig. 2.

[0020] In addition, although the suction port 5a in this embodiment is formed on the lower surface 4a of the nonabsorbent body 4, this is not limited to this configuration. The suction port 5a may be formed on the inner surface 4c of the nonabsorbent body 4 (see FIG. 8). Furthermore, although the exhaust port 5b in this embodiment is formed on the upper surface 4b of the nonabsorbent body 4, this is not limited to this configuration. The exhaust port 5b may be formed on the outer surface 4d of the nonabsorbent body 4, for example.

[0021] As shown in FIG. 1 and FIG. 2, the liquid removal tool 1 of this embodiment is connected to the outlet 5b of the liquid suction path 5 and includes a suction tube 6 capable of sucking liquid through the liquid suction path 5. Specifically, one end of the suction tube 6 is connected to the outlet 5b of the liquid suction path 5. As shown in FIG. 2, the other end of the suction tube 6 is configured to be connectable to a suction device 400. That is, by performing a suction operation by the suction device 400, liquid can be sucked from the suction port 5a of the liquid suction path 5 through the outlet 5b and the suction tube 6. In this embodiment, the liquid removal tool 1 includes the suction tube 6, but is not limited to this configuration. The liquid removal tool 1 may be configured without the suction tube 6 as long as it is capable of sucking liquid through the liquid suction path 5 of the non-absorbent body 4.

[0022] FIG. 3 is a diagram showing a transport container 100 as an example of a transport container that can be used with the liquid removal tool 1 shown in FIG. 1. The liquid removal tool 1 can be used to remove a liquid 105 in the transport container 100 in which a transplant X is stored. The transplant X, such as a cell sheet, is transported to an intensive care unit or the like where the transplant is performed using the transport container 100. The thickness of the cell sheet as the transplant X is, for example, about 100 μm, and the diameter of the cell sheet is, for example, about 60 mm. However, the thickness and diameter (size) of the cell sheet can be set appropriately. The cells constituting the transplant X include, for example, somatic stem cells (adult stem cells), or differentiated cells derived from ES cells (embryonic stem cells) or iPS cells (induced pluripotent stem cells). Somatic stem cells include, for example, mesenchymal stem cells, vascular endothelial stem / progenitor cells, and skeletal myoblast cells (myoblast cells). Differentiated cells include, for example, cardiomyocytes and fibroblast cells. In addition, the cells may include, for example, cell lines and genetically-modified cells.

[0023] The transport container 100 shown in FIG. 3 includes a container body 101 including a circular bottom plate portion 102 and a cylindrical portion 103 rising from the outer edge of the bottom plate portion 102. The container body 101 includes a storage recess 104 formed by the bottom plate portion 102 and the cylindrical portion 103. The transplant X is transported to an intensive care unit or the like where the transplant is performed while being stored in the storage recess 104 of the container body 101 of the transport container 100. The storage recess 104 is filled with a liquid 105 so that the transplant X is not deformed or moved due to vibration, impact, or the like during transportation. In other words, the transplant X is transported while being surrounded by the liquid 105 in the storage recess 104. The liquid 105 is not particularly limited as long as it has little effect on the transplant X. The liquid 105 may be, for example, water, physiological saline, physiological buffer solution, or the like. The transport container 100 further includes a lid 106 that can be attached to cover the storage recess 104 of the container body 101 .

[0024] As shown in FIG. 3, the graft X, which is transported in a state housed in the transport container 100, is taken out in an intensive care unit or the like where the transplantation is performed, and transferred to a transplantation device capable of delivering the graft X to a target site in a living body. The graft X is delivered to a target site in a living body by the transplantation device, and is released at the target site. In this manner, the graft X is transplanted to a target site in a living body. Here, when the graft X is taken out from the transport container 100, the liquid 105 filled in the storage recess 104 is removed. The liquid removal tool 1 of this embodiment is used when removing the liquid 105 from the storage recess 104 of the container body 101 of the transport container 100. FIG. 4 is a diagram showing a state in which the liquid removal tool 1 is used when removing the liquid 105 from the storage recess 104 of the container body 101 of the transport container 100. Note that in FIG. 4, for convenience of explanation, the suction tube body 6 is omitted from the illustration.

[0025] As shown in FIG. 4, the annular main body 2 is placed in the storage recess 104 to remove the liquid 105 in the storage recess 104. Specifically, the annular main body 2 is placed on the surface of the liquid 105 in the storage recess 104 with the axial direction A aligned along the vertical direction and the lower surface 4a of the non-absorbent 4 facing vertically downward. In this manner, the absorbent 3 of the main body 2 is impregnated with the liquid 105 by capillary action and can absorb the liquid 105. In addition, the non-absorbent 4 of the main body 2 is in a state in which it can suck the liquid 105 through the liquid suction path 5 (see FIG. 2). Specifically, in this embodiment, the suction port 5a of the liquid suction path 5 is located in the liquid 105. Therefore, by performing a suction operation using the suction device 400 (see FIG. 2) connected to the suction tube 6, the liquid 105 in the storage recess 104 is sucked into the liquid suction path 5 through the suction port 5a. The liquid 105 sucked into the liquid suction path 5 through the suction port 5 a is discharged from within the accommodation recess 104 through the discharge port 5 b of the liquid suction path 5 and the suction pipe body 6 .

[0026] In this manner, according to the liquid removal tool 1, the liquid 105 in the containing recess 104 can be removed from each of the positions of the absorbent 3 and the non-absorbent 4 that are connected in the circumferential direction B.

[0027] Fig. 5 is a plan view of the state shown in Fig. 4 in which the liquid 105 in the accommodating recess 104 is being removed by the liquid removing instrument 1, as viewed along the axial direction A of the main body 2. For ease of explanation, the suction tube 6 is omitted from Fig. 5. The main body 2 is placed on the surface of the liquid 105 so that the implant X in the accommodating recess 104 is located within the through-hole 2a in the plan view shown in Fig. 5.

[0028] If the amount of the liquid 105 removed varies depending on the position in the circumferential direction B of the main body 2, the liquid 105 in the receiving recess 104 moves. If such a movement of the liquid 105 occurs in the receiving recess 104, the implant X in the receiving recess 104 may also move. FIG. 6A is the same plan view as FIG. 5, and illustrates a case in which the amount of the liquid 105 removed is relatively larger on the left side than on the right side. In the example shown in FIG. 6A, the implant X in the receiving recess 104 may move to the left (see the white arrow in FIG. 6A). Also, FIG. 6B is the same plan view as FIG. 5, and illustrates a case in which the amount of the liquid 105 removed is relatively larger on the right side than on the left side. In the example shown in FIG. 6B, the implant X in the receiving recess 104 may move to the right (see the white arrow in FIG. 6B). In this way, if the amount of the liquid 105 removed varies depending on the position in the circumferential direction B of the main body 2, the implant X moves, and at this time, unexpected deformation or damage may occur to the implant X. An example of the unexpected deformation of the implant X is wrinkles in the sheet-like material as the implant X.

[0029] In contrast, in the liquid removal instrument 1, the non-absorbent body 4 is provided with a liquid suction path 5, and the amount of liquid 105 suctioned can be adjusted through the liquid suction path 5. That is, with the liquid removal instrument 1, the amount of liquid 105 removed can be adjusted according to the position in the circumferential direction B of the main body part 2. Therefore, even if the amount of liquid 105 removed varies depending on the position in the circumferential direction B of the main body part 2, the movement of the implant X as shown in FIGS. 6A and 6B can be suppressed by adjusting the amount of liquid suctioned through the liquid suction path 5. That is, unexpected deformation or damage to the implant X due to movement of the implant X within the accommodation recess 104 can be suppressed.

[0030] It is not necessary to perform suction of the liquid 105 through the liquid suction path 5. In other words, when the liquid 105 is slowly absorbed by the absorbent 3 and the transplant X does not move within the housing recess 104, it is not necessary to adjust the amount of the liquid 105 being suctioned through the liquid suction path 5. As shown in Figures 6A and 6B, when the transplant X moves within the housing recess 104, the amount of the liquid 105 being suctioned through the liquid suction path 5 may be adjusted.

[0031] The main body part 2 of this embodiment includes eight absorbents 3 and eight nonabsorbents 4, but the number of absorbents 3 and nonabsorbents 4 is not limited. As shown in FIG. 7A, the main body part 2 may be configured, for example, by two absorbents 3 and two nonabsorbents 4 alternately connected in the circumferential direction B. Furthermore, as shown in FIG. 7B, the main body part 2 may be configured, for example, by four absorbents 3 and four nonabsorbents 4 alternately connected in the circumferential direction B. Furthermore, in the main body part 2 of this embodiment, the absorbents 3 and the nonabsorbents 4 are alternately connected in the circumferential direction B, but in a part of the circumferential direction B, there may be a position where the absorbents 3 are connected to each other or the nonabsorbents 4 are connected to each other.

[0032] Next, a modified example of the nonabsorbent body 4 described above will be described with reference to Fig. 8. Fig. 8 is a cross-sectional view of the nonabsorbent body 4. The nonabsorbent body 4 shown in Fig. 8 has another liquid suction path 7 defined therein in addition to the liquid suction path 5 described above. Hereinafter, for ease of explanation, the liquid suction path 5 shown in Fig. 8 will be referred to as the "first liquid suction path 5," and the liquid suction path 7 shown in Fig. 8 will be referred to as the "second liquid suction path 7."

[0033] The suction port 5a of the first liquid suction path 5 shown in Fig. 8 is formed on the inner surface 4c of the nonabsorbent 4. The discharge port 5b of the first liquid suction path 5 shown in Fig. 8 is formed on the upper surface 4b of the nonabsorbent 4, similar to Fig. 2. Furthermore, the first liquid suction path 5 may extend linearly or curvedly within the nonabsorbent 4.

[0034] The second liquid suction path 7 shown in Fig. 8 has a suction port 7a on one surface in the circumferential direction B. In other words, the suction port 7a of the second liquid suction path 7 opens toward the absorbent 3 adjacent to the nonabsorbent 4 in the circumferential direction B. The discharge port 7b of the second liquid suction path 7 shown in Fig. 8 is formed on the upper surface 4b of the nonabsorbent 4, similar to the discharge port 5b of the first liquid suction path 5. In addition, the second liquid suction path 7 may extend linearly or curvedly within the nonabsorbent 4.

[0035] 8, the liquid removal instrument 1 may include a suction tube 8 that is connected to the outlet 7b of the second liquid suction path 7 and is capable of sucking liquid 105 (see FIG. 4, etc.) through the second liquid suction path 7. Specifically, one end of the suction tube 8 is connected to the outlet 7b of the second liquid suction path 7. The other end of the suction tube 8 is configured to be connectable to a suction device 400 (see FIG. 2). In other words, by performing a suction operation using the suction device 400, the liquid 105 (see FIG. 4, etc.) absorbed by the absorber 3 can be sucked from the suction port 7a of the second liquid suction path 7 through the outlet 7b and the suction tube 8.

[0036] In this way, by providing the nonabsorbent 4 with the second liquid suction path 7 in addition to the first liquid suction path 5, the liquid 105 (see FIG. 4) absorbed by the absorbent 3 can be removed to the outside of the accommodation recess 104 (see FIG. 4) through the second liquid suction path 7. In other words, the variation in the amount of removed liquid 105 depending on the position in the circumferential direction B of the main body portion 2 can be adjusted not only for the position of the nonabsorbent 4 in the circumferential direction B, but also for the position of the absorbent 3 in the circumferential direction B by using the second liquid suction path 7. Therefore, the variation in the amount of removed liquid 105 depending on the position in the circumferential direction B of the main body portion 2 can be adjusted with higher precision.

[0037] Furthermore, by providing the non-absorbent body 4 with the second liquid suction path 7 in addition to the first liquid suction path 5, the liquid 105 absorbed by the absorbent body 3 can be sucked in, so that the amount of liquid 105 that can be absorbed by the absorbent body 3 can be reduced. In other words, the absorbent body 3 can be made smaller. As a result, the entire main body portion 2 can be made smaller.

[0038] In FIG. 8, the non-absorbent 4 is provided with the second liquid suction path 7, and the liquid 105 absorbed by the absorbent 3 (see FIG. 4, etc.) can be sucked. However, the liquid 105 absorbed by the absorbent 3 may be sucked by another method. FIG. 9 is a diagram showing an example of a configuration in which the liquid 105 absorbed by the absorbent 3 can be directly sucked by the suction tube 8 without passing through the second liquid suction path 7 of the non-absorbent 4. The non-absorbent 4 of the liquid removal tool 1 shown in FIG. 9 does not have the second liquid suction path 7 shown in FIG. 8. The liquid removal tool 1 shown in FIG. 9 includes a membrane 9 and a suction tube 8. The membrane 9 covers the main body 2. Specifically, the membrane 9 covers one surface of the main body 2 in the axial direction A, including the upper surface 4b of the non-absorbent 4. More specifically, the membrane 9 covers the through-hole 2a, the absorbent 3, and the non-absorbent 4. The suction tube 8 penetrates the membrane 9 and is capable of sucking liquid 105 (see FIG. 4, etc.) through the absorbent 3. According to the example shown in FIG. 9, the suction tube 8 can suck liquid 105 (see FIG. 4, etc.) through the absorbent 3 without passing through the non-absorbent 4.

[0039] 9, the provision of the membrane 9 can prevent the suction tube 8 from suctioning air contained in the absorber 3. In other words, compared to a configuration in which the membrane 9 is not provided, the suction efficiency of the suction tube 8 in suctioning the liquid 105 (see FIG. 4, etc.) can be improved.

[0040] In FIG. 9, the suction pipe body 6 also penetrates the membrane body 9 and is connected to the outlet 5b of the liquid suction path 5 of the non-absorbent body 4.

[0041] Fig. 10 is a diagram showing another modified example of the liquid removal tool 1. The liquid removal tool 1 shown in Fig. 10 differs from the configuration shown in Fig. 1 in that it further includes a cylindrical body 10. The cylindrical body 10 is disposed in a through hole 2a defined by the main body portion 2, and is attached to the main body portion 2 so as to be movable in the axial direction A relative to the main body portion 2. Specifically, the cylindrical body 10 shown in Fig. 10 has an outer circumferential surface in contact with an inner circumferential surface of the main body portion 2, and is slidable in the axial direction A relative to the main body portion 2.

[0042] In addition, the cylindrical body 10 is formed with a communication hole 11 that communicates with the inside and outside in the radial direction C. A plurality of communication holes 11 are arranged at different positions in the circumferential direction B. A plurality of communication holes 11 are arranged at different positions in the axial direction A. The cross-sectional shape of the communication hole 11 is not particularly limited, and may be, for example, a polygonal shape such as a circle, an ellipse, or a triangle. However, the cross-sectional shape of the communication hole 11 is preferably a circle. When the implant X is a circular flat sheet, the maximum cross-sectional length of the communication hole 11 (diameter in the case of a communication hole 11 having a circular cross-section) is smaller than the diameter of the implant X, and is preferably 1 / 6 or less of the diameter of the implant X. In addition, the maximum cross-sectional length of the communication hole 11 may be smaller than the thickness of the implant X. In this way, the circular flat sheet-like implant X can be positioned inside the cylindrical body 10 without moving outside the radial direction C of the cylindrical body 10 through the communication hole 11.

[0043] As shown in FIG. 10, the cylindrical body 10 is placed in the receiving recess 104 so that one end 10a in the axial direction A of the cylindrical body 10 abuts against the bottom surface of the receiving recess 104. The liquid 105 in the receiving recess 104 can move inward and outward in the radial direction C of the cylindrical body 10 through the communication hole 11. At this time, the implant X in the receiving recess 104 is located in the cylindrical body 10. In this state, the liquid 105 in the receiving recess 104 is removed from the absorbent 3 (see FIG. 1, etc.) and the non-absorbent 4 (see FIG. 1, etc.) of the main body 2. Specifically, the liquid 105 in the receiving recess 104 is removed while the main body 2 is moved relatively in the axial direction A with respect to the cylindrical body 10 so as to approach the one end 10a of the cylindrical body 10 abutting against the bottom surface of the receiving recess 104.

[0044] By providing the liquid removal instrument 1 with such a cylindrical body 10, it is possible to prevent the transplant X from entering the lower side of the main body part 2 while removing the liquid 105 in the accommodating recess 104. In other words, even if the transplant X moves within the accommodating recess 104 during the process of removing the liquid 105 in the accommodating recess 104, it is possible to prevent the transplant X from entering the lower side of the main body part 2, and the movement of the transplant X within the accommodating recess 104 can be restricted within the cylindrical body 10. Therefore, it is possible to prevent the transplant X from being pinched between the main body part 2 and the bottom surface of the accommodating recess 104 and being damaged.

[0045] The material of the cylindrical body 10 is not particularly limited, but may be made of resin, for example.

[0046] The range of movement of the cylindrical body 10 in the axial direction A relative to the main body 2 may be limited. In other words, the cylindrical body 10 may be movable in the axial direction A only within a predetermined range in the axial direction A relative to the main body 2. Such a restriction of the range of movement may be realized, for example, by providing a flange portion that protrudes outward in the radial direction C at the end of the cylindrical body 10 in the axial direction A. Also, the above-mentioned restriction of the range of movement may be realized by providing a convex portion on one of the main body 2 and the cylindrical body 10, and providing a guide recess on the other of the main body 2 and the cylindrical body 10 so that the convex portion can move in the axial direction A.

[0047] The liquid removal device according to the present disclosure is not limited to the specific configurations shown in the above-described embodiment and modified examples, and various modifications, changes, and combinations are possible without departing from the scope of the claims.
