Description

  The present invention relates to a blood collection table that supports a part of the body of a blood collection subject in blood collection, and particularly to a blood collection table in which a support surface that supports a part of the body is covered with a sheet.

  In blood collection performed for a blood test or the like, a blood collection needle attached to a syringe or a holder of a vacuum blood collection tube is pierced until reaching a vein in a part of the body of the blood sample such as an arm. At this time, a blood collection table is used to stably place a part of the body through which the blood collection needle is pierced. This blood collection table has various forms such as a pillow-shaped table placed on a work table or the like and a table provided with legs that can be placed on the floor (see, for example, Patent Document 1 and Patent Document 2).

  In a conventional blood collection table, a member on which a part of the body is placed is composed of a relatively soft member such as a cushion material, and the support surface that contacts the part of the body in the member such as the cushion material is hygienic. It is covered with cloth from a natural point of view.

  For example, when blood is collected continuously from a large number of blood samples, such as in a health examination at work, a blood collection table may be reused for a plurality of blood samples. In blood collection, blood may be scattered on the blood collection table. Reuse of a blood collection table on which another person's blood is attached is not only unsanitary but may be an infection route for infectious diseases. Even if blood is not attached, it is difficult to say that it is hygienic that a blood collection table in contact with another person's body is reused as it is. However, each time a blood sample is changed, the cost required for blood collection increases if the blood collection table is replaced or the blood collection table is made disposable. Further, replacing only the cloth or the like that covers the support surface in the blood collection table makes the blood collection operation inefficient.

  The present invention has been made in view of these circumstances, and an object of the present invention is to provide a blood collection table that is hygienic and can realize rapid blood collection at low cost.

  (1) A blood collection table according to the present invention includes a support table having a support surface capable of supporting a part of the body of a blood sample, supply means for supplying a belt-like sheet to the support table, and supply from the supply means And receiving means for drawing in and storing the sheet covering the support surface.

  The blood collection table according to the present invention supports a part of the body of a blood collection subject during blood collection. The body part is an arm, a leg, or the like, but is generally an arm. The support surface that supports a part of the body is a part of the support table, and is generally the upper surface of the support table. This support surface is covered with a belt-like sheet. The band-shaped sheet is, for example, a sheet made of cloth, paper, or other material capable of absorbing blood, and has a width that can substantially cover the support surface of the support base, and is sufficiently longer than the support surface. is there. The belt-like sheet may be used repeatedly by washing or the like, but is preferably disposable from the viewpoint of hygiene and prevention of infection.

  The belt-like sheet is supplied from the supply means. As will be described later, the supply means is exemplified by a first core member in which a belt-like sheet is wound, a space in which the belt-like sheet is folded and accommodated in a stacked state, and the like. The sheet supplied from the supply means covers the support surface of the support base. The sheet covering the support surface can be retracted by the accommodating means. The accommodating means is exemplified by a second core material capable of winding a belt-like sheet as described later, a pair of rollers for holding the belt-like sheet and conveying it to the housing space.

  When the blood collection table is used, a part of the body of the blood sample is supported on the support surface covered with the sheet. And after blood collection is performed, the sheet | seat which covers a support surface is drawn in by an accommodating means. Along with this, an unused portion of the sheet is supplied from the supply means to the support surface to cover the support surface. Thus, a part of the body of the blood sample is always supported on a new sheet.

  (2) The supply means may include a first core member that is rotatably supported by the support base and on which a belt-like sheet is wound.

  The belt-like sheet is wound around the first core material. The first core material is, for example, a cylindrical or columnar member. The axial direction of the first core material and the width direction of the sheet are matched, and the sheet is wound around the first core material. The first core member is rotatably supported on the support base. While the first core member is rotated, the sheet wound around the first core member is taken out in the length direction. The aspect in which the sheet is taken out by the rotation of the first core material in this way is referred to as “unwindable” in the present invention. As a result, the belt-like sheet is accommodated in a compact manner and can be easily supplied. The first core member may be rotated manually or using a driving source such as a motor.

  (3) The housing means may include a second core member that is rotatably supported by the support base and is connected so that a sheet covering the support surface is wound.

  One end side of the sheet covering the support surface of the support base is connected to the second core member. The second core material is, for example, a tubular or columnar member. The axial direction of the second core material and the width direction of the sheet are matched, and the leading end side of the sheet is connected to the second core material. The second core member is rotatably supported on the support base. While the second core member is rotated, a sheet covering the support surface of the support base is wound around the second core member. Thus, the aspect in which the sheet is wound by the rotation of the second core member is referred to as “winding is possible” in the present invention. Thereby, a strip | belt-shaped sheet | seat is accommodated compactly and it becomes possible to draw in easily. The second core member may be rotated manually or using a drive source such as a motor.

  (4) At least one of the first core material and the second core material may be detachable from the support base.

  Thereby, after using all the strip | belt-shaped sheets, if it replaces | exchanges for the 1st core material and the 2nd core material by which the new sheet was wound, a support stand can be reused. The first core material after use can be reused by winding a new sheet.

  (5) A handle that rotates together with the second core material may be provided at one end of the second core material.

  Examples of the handle include those that can be held between fingers, such as a dial-shaped one provided at one end of the second core member. This handle improves the operability when manually rotating the second core member.

  (6) The support base includes an elastic deformation member having the support surface, a support plate for supporting the elastic deformation member, and a base body having a pair of legs extending downward from the support plate. It may be provided. And as for the said 1st core material and the said 2nd core material, each both ends may be supported by said pair of leg part, respectively.

  The elastic deformation member is made of, for example, a sponge or a low-resilience polyurethane. By forming the support surface with the elastic deformation member, it is possible to give a soft touch with less pain to a part of the body to be supported. The elastic deformation member is supported by a support plate, and the support plate is supported at a predetermined height on a work table by a pair of legs. Each of the first core material and the second core material is rotatably supported with both ends in the axial direction supported by a pair of leg portions, respectively. In other words, the first core material and the second core material are installed on the pair of leg portions below the support plate. Thereby, the blood collection table can be made compact by using the space below the support plate as the accommodation space for the first core member, the second core member, and the belt-like sheet wound around them.

  According to the present invention, the support surface that supports a part of the body of the blood sample is covered with the belt-shaped sheet, and after blood collection, the sheet that has covered the support surface is drawn into the storage means and supplied. Since the unused part of the sheet is supplied from the means to the support surface, a part of the body of each blood sample is always supported on a new sheet. Therefore, a hygienic blood collection table is realized. In addition, since the sheet covering the support surface can be continuously replaced by the supply unit and the storage unit, rapid blood collection can be realized at low cost.

  Hereinafter, preferred embodiments of the present invention will be described. In addition, this embodiment is only one embodiment of this invention, and it cannot be overemphasized that an embodiment can be changed in the range which does not change the summary of this invention.

[Schematic configuration of blood collection table 10]
As shown in FIG. 1, the blood collection table 10 has a substantially rectangular parallelepiped shape that can be placed on a work table or a desk on which blood is collected, and a part of the body of the blood sample is placed on the blood collection table 10 during blood collection. By supporting the body part. A part of the body that can be supported by blood collection table 10 is not particularly limited, and examples thereof include any part such as an arm or a leg where a vein that pierces a blood collection needle exists, but blood collection table 10 mainly has a lower arm portion. It is assumed to be placed with the elbows on the bottom. The blood collection table 10 includes a support table 11, a belt-like sheet 12, a first core material 13, and a second core material 14 as main members.

[Support 11]
As shown in FIG. 2, the support base 11 mainly includes a base body 20 and an elastic deformation member 21 supported by the base body 20. The base body 20 has a U-shape that is open at the bottom in the longitudinal section (for example, see FIG. 5), a support plate 22 that serves as a U-shaped top plate, a pair of legs 23, 24. The support plate 22 is a flat plate that is rectangular in plan view. A pair of leg portions 23, 24 extend downward from both longitudinal edges of the support plate 22. The support plate 22 and the leg portions 23 and 24 are integrally formed as one member, and have a U-shape in which the lower side is opened in a front view (a direction indicated by an arrow 25 in FIG. 2). The support plate 22 is horizontally supported at a predetermined height from the upper surface of a work table or the like by the pair of leg portions 23 and 24. Although not shown in each figure, it is preferable that a member having a high coefficient of static friction such as rubber is provided on the bottom surfaces of the pair of leg portions 23 and 24 because the support table 11 does not slip on the upper surface of the work table or the like. It is.

  The pair of leg portions 23 and 24 are provided with shaft holes 26, 27, 28, and 29 for rotatably supporting a first core member 13 and a second core member 14 described later. The shaft holes 26 to 29 are penetrated in the thickness direction at predetermined positions of the pair of leg portions 23 and 24. The shaft holes 26 and 27 form a pair to support the first core member 13 and are formed in the leg portions 23 and 24, respectively. The shaft holes 28 and 29 are paired to support the second core member 14 and are formed in the leg portions 23 and 24, respectively. In FIG. 2, the shaft holes 27 and 29 formed in the leg portion 24 do not appear.

  In the leg portion 23, the shaft hole 26 has a small diameter portion 30 and a large diameter portion 31 formed on the same axis 34. In the leg part 23, the small diameter part 30 is arrange | positioned at the inner surface side which opposes the other leg part 24, and the large diameter part 31 is arrange | positioned at the outer surface side. The small diameter portion 30 has an inner diameter corresponding to the outer diameter of the shaft portion 40 of the first core member 13 described later, and supports the shaft portion 40. The large-diameter portion 31 has an inner diameter corresponding to the outer diameter of the handle 41 of the first core member 13, and the handle 41 is rotatably fitted therein. The lengths of the small-diameter portion 30 and the large-diameter portion 31 in the direction of the axis 34 are not particularly limited, but in this embodiment, each of the small-diameter portion 30 and the large-diameter portion 31 corresponds to about half the thickness of the leg portion 23. Although not shown in FIG. 2, the shaft hole 27 formed in the leg portion 24 has an inner diameter equivalent to the small diameter portion 30 and is formed on the axis 34, and the shaft portion 40 is coupled with the small diameter portion 30. Pivot.

  In the leg portion 23, the shaft hole 28 has a small diameter portion 32 and a large diameter portion 33 formed on the same axis 35. In the leg part 23, the small diameter part 32 is arrange | positioned at the inner surface side which opposes the other leg part 24, and the large diameter part 33 is arrange | positioned at the outer surface side. The small diameter portion 32 has an inner diameter corresponding to the outer diameter of the shaft portion 50 of the second core member 14 to be described later, and pivotally supports the shaft portion 50. The large diameter portion 33 has an inner diameter corresponding to the outer diameter of the handle 51 of the second core member 14, and the handle 51 is rotatably fitted therein. The lengths of the small diameter portion 32 and the large diameter portion 33 in the direction of the axis 35 are not particularly limited, but in the present embodiment, each of the small diameter portion 32 and the large diameter portion 33 corresponds to about half the thickness of the leg portion 23. Although not shown in FIG. 2, the shaft hole 29 formed in the leg portion 24 has an inner diameter equivalent to the small diameter portion 32 and is formed on the axis 35, and the shaft portion 50 is coupled with the small diameter portion 32. Pivot.

  With the support base 11 placed on the upper surface of a horizontal work table or the like, the shaft holes 26 to 29 formed in the leg portions 23 and 24 have the same height of the axis lines 34 and 35. And both are arranged in the horizontal direction. Further, the shaft hole 26 and the shaft hole 28 in the leg portion 23 are separated along the longitudinal direction of the support plate 22. Although not appearing in FIG. 2, similarly, the shaft hole 27 and the shaft hole 29 in the leg portion 24 are separated along the longitudinal direction of the support plate 22. That is, the axis 34 and the axis 35 are separated along the longitudinal direction of the support plate 22. The distance between the shaft holes 26 and 27 and the shaft holes 28 and 29 is determined by the thickness of the belt-like sheet 12 wound around the first core member 13 and the thickness of the belt-like sheet 12 wound around the second core member 14. The belt-like sheet 12 and the second core wound around the first core member 13 are set in consideration, and the first core member 13 and the second core member 14 are pivotally supported in the shaft holes 26 to 29. The strips 12 wound around the material 14 are separated so as not to contact each other.

  An elastic deformation member 21 is fixed to the upper surface of the support plate 22. The elastic deformation member 21 is a flat plate that is rectangular in plan view, and its short direction is slightly narrower than the length of the support plate 22 in the short direction minus the thickness of each of the leg portions 23 and 24. The longitudinal direction is equivalent to the longitudinal direction of the support plate 22. The elastic deformation member 21 is formed using low-resilience urethane as a main material, and can be elastically deformed so as to contract the volume against an external force. Such an elastically deformable member 21 is fixed to the upper surface of the support plate 22 such that both ends (small face surfaces) in the longitudinal direction are aligned with both ends (small face surfaces) of the support plate 22. The upper surface of the elastic deformation member 21 fixed to the support plate 22 becomes a support surface that can support a part of the body of the blood sampled person during blood collection.

  As shown in FIG. 1, the upper surface, that is, the support surface of the elastic deformation member 21 is covered with the belt-like sheet 12. The belt-like sheet 12 is, for example, a sheet made of cloth, paper, or other material that can absorb blood. The width of the belt-like sheet 12 is equal to the length of the elastic deformation member 21 in the short direction. Moreover, the length of the strip | belt-shaped sheet | seat 12 is fully longer than the length of the longitudinal direction of the elastic deformation member 21, and is wound around the 1st core material 13 in multiple times so that it may mention later. Therefore, the belt-like sheet 12 can substantially cover the upper surface of the elastic deformation member 21.

  Since the first core member 13 around which the belt-like sheet is wound and the second core member 14 around which the belt-like sheet 12 is wound up have the same structure, a detailed structure will be described below by taking the first core member 13 as an example. Explained. In addition, the 1st core material 13 is an example of the supply means in this invention, and the 2nd core material 14 is an example of the accommodating means in this invention.

  As shown in FIG. 3, the first core member 13 includes a shaft portion 40 and a handle 41. The shaft portion 40 has a substantially cylindrical shape, and the length in the direction of the axis 42 is slightly longer than the distance between the pair of leg portions 23 and 24. Further, the outer diameter of the shaft portion 40 is constant with respect to the direction of the axis 42, and as described above, the shaft portion 40 has a size that can be rotatably fitted in the small diameter portion 30 and the shaft hole 27 of the shaft hole 26. On the first end 43 side of the shaft portion 40, a flange portion 45 is provided with a slight distance from the first end 43 in the direction of the axis 42. The collar portion 45 has a disk shape whose outer diameter is larger than the outer diameter of the cylindrical portion of the shaft portion 40. As shown in FIG. 5, a part of the first end 43 side from the flange portion 45 is fitted into the small diameter portion 30 of the shaft hole 26. On the other hand, the second end 44 side of the shaft portion 40 is fitted into the shaft hole 27. Accordingly, the shaft portion 40 is supported at the first end 43 and the second end 44 by the pair of leg portions 23 and 24, respectively. Although not shown in FIG. 3, the shaft portion 40 is appropriately provided with a notch and a bonding portion for fixing one end of the belt-like sheet 12 in order to wind the belt-like sheet 12 as will be described later. .

  The handle 41 is attached to the first end 43 of the shaft portion 40. The handle 41 includes a disk part 46, a knob part 47, and a penetration part 48. The disk portion 46 has a disk shape whose outer diameter is larger than the outer diameter of the shaft portion 40, and the outer diameter substantially matches the large diameter portion 31 of the shaft hole 26. Further, the thickness of the disk portion 46 is slightly smaller than the depth of the large diameter portion 31. Accordingly, the disk portion 46 can be fitted into the large diameter portion 31. The disk portion 46 is provided with a knob portion 47 that protrudes outward from the surface thereof and extends in the diameter direction. The knob portion 47 protrudes outward from the large-diameter portion 31 in a state where the disk portion 46 is fitted into the large-diameter portion 31. Both sides of the knob portion 47 are surfaces of the disk portion 46, and the disk portion 46 can be rotated in the large-diameter portion 31 when the knob portion 47 is rotated while being sandwiched between fingers. A penetrating portion 48 protrudes from the back surface of the disk portion 46. The penetration portion 48 has a cylindrical shape that substantially matches the inner diameter of the shaft portion 40. When the penetrating portion 48 is inserted into the inner space of the shaft portion 40, the handle 41 is fixed to the first end 43 of the shaft portion 40, and the handle 41 and the shaft portion 40 are rotated together. Therefore, the rotation imparted to the knob portion 47 is transmitted to the shaft portion 40, and the handle 41 and the shaft portion 40 rotate integrally.

  In addition, although description of the detailed structure of the 2nd core material 14 is abbreviate | omitted, the 2nd core material 14 also consists of the axial part 50 and the handle 51 similar to the 1st core material 13. FIG. In the same manner as the first core member 13 shown in FIG. 5, both ends (first end and second end) of the shaft portion 50 are fitted into the small diameter portion 33 and the shaft hole 29 of the shaft hole 27, respectively. The shaft portion 50 is supported by the pair of leg portions 23 and 24, respectively. Moreover, since the strip | belt-shaped sheet | seat 12 is wound up so that it may mention later, the shaft part 50 is suitably provided with the notch | incision for fixing the end of the strip | belt-shaped sheet | seat 12, or an adhesion part. The handle 51 is fixed to the first end of the shaft portion 50 and rotates integrally with the shaft portion 50.

  As shown in FIG. 4, the belt-like sheet 12 is wound around the first core material 13. The axis 42 of the shaft portion 40 of the first core member 13 is aligned with the width direction of the belt-like sheet 12, and the belt-like sheet 12 is wound around the shaft portion 40. The number of windings of the belt-like sheet 12 is not particularly limited as long as the first core member 13 around which the belt-like sheet 12 is wound fits into the space below the support plate 22 in the base body 20. The belt-like sheet 12 wound around the first core member 13 is taken out in the length direction, extends to the back side of the base body 20 (arrow 36 in FIG. 4), and further supports the support plate 22 and the small edge of the elastic deformation member 21. It extends upward along the surface and reaches the upper surface (support surface) of the elastic deformation member 21. The belt-like sheet 12 is extended to the front side of the base body 20 (arrow 25 in FIG. 4), and the upper surface of the elastic deformation member 21 is covered with the belt-like sheet 12.

  The belt-like sheet 12 covering the upper surface of the elastic deformation member 21 is extended downward along the small deformation surfaces of the elastic deformation member 21 and the support plate 22 on the front side of the base body 20, and further to the space below the support plate 22. It extends and is connected to the shaft portion 50 of the second core member 14. Also in the shaft portion 50, as in the shaft portion 40, the axial direction of the shaft portion 50 and the width direction of the belt-like sheet 12 are matched.

  As described above, when the first core 12 is rotated in the clockwise direction in FIG. 4, the belt-like sheet 12 whose both ends in the length direction are connected to the first core 13 and the second core 14, respectively. One core material 12 is taken out and supplied to the upper surface of the elastic deformation member 21. The aspect in which the belt-like sheet 12 is taken out by the rotation of the first core member 13 in this way is referred to as “unwindable” in the present invention. On the other hand, when the second core member 14 is rotated in the clockwise direction in FIG. 4, the belt-like sheet 12 is wound around the second core member 14 and is drawn in from the upper surface of the elastic deformation member 21 and accommodated. The aspect in which the belt-like sheet 12 is wound by the rotation of the second core member 14 is referred to as “can be wound” in the present invention.

  The first core member 13 and the second core member 14 are detachable from the support base 11. The structure in which the first core member 13 is supported on the support base 11 and the structure in which the second core member 14 is supported on the support base 11 are the same except that their positions are different. A method for attaching and detaching the core material 13 will be described as an example.

  As shown in FIG. 5, the first core member 13 around which the belt-like sheet 12 is wound is inserted into the shaft holes 26 and 27 formed in the leg portions 23 and 24 below the support plate 22 and rotated. It is supported freely. In the shaft hole 26, the first end 43 of the shaft portion 40 is fitted into the small diameter portion 30. The first end 43 is fitted into the small diameter portion 30 until the flange portion 45 provided on the shaft portion 40 contacts the inner surface of the leg portion 23. In this state, the first end 43 is in the small diameter portion 30. The handle 41 is fitted into the large-diameter portion 31 from the outer surface side of the leg portion 23. When the disk portion 46 of the handle 41 is inserted until it comes into contact with the inner surface of the large diameter portion 31, the penetration portion 48 is press-fitted into the shaft portion 40. Thus, the shaft portion 40 and the handle 41 are connected in a state where the leg portion 23 is held between the flange portion 45 and the disc portion 46. On the other hand, the second end 44 of the shaft portion 40 is fitted into the shaft hole 27 of the leg portion 24. The second end 44 side of the shaft portion 40 is allowed to move in the direction of the axis 34 with respect to the shaft hole 27, but as described above, the flange portion 45 and the disk portion 46 narrow the leg portion 23. By holding the first core member 13, the first core member 13 can rotate about the axis 34 without moving in the direction of the axis 34.

  When removing the first core member 13 from the support base 11, the handle 41 is removed from the shaft portion 40. When the handle 41 is pulled out of the leg portion 23, the penetration portion 48 that has been press-fitted into the shaft portion 40 is pulled out, and the handle 41 can be detached from the shaft portion 40. When the handle 41 is removed, the shaft portion 40 is movable with respect to the axis 34 in the direction in which the second end 44 protrudes to the outside of the leg portion 24 (left direction in FIG. 5). When the shaft portion 40 is moved in this manner, the second end 44 moves to the outer surface side of the leg portion 24 in the shaft hole 27, and the first end 43 moves to the inner surface side of the leg portion 23 in the shaft hole 26. The first end 43 comes out of the shaft hole 26. When the first end 43 that has come out of the shaft hole 26 is moved to the lower side of the leg portion 23, the second end 44 of the shaft portion 40 can be extracted from the shaft hole 27. In this way, the first core member 13 is removed from the support base 11. In addition, when moving the first end 43 of the shaft portion 40 to the lower side of the leg portion 23, the vicinity of the second end 44 is twisted with respect to the shaft hole 27, but between the shaft hole 27 and the shaft portion 40. As shown in FIG. 5, the tapered portion 37 that enlarges the diameter of the shaft hole 27 is provided on the inner surface side of the leg portion 24, so that the vicinity of the second end 44 can be twisted with respect to the shaft hole 27. It becomes. In addition, when attaching the 1st core material 13 to the support stand 11, the reverse procedure should just be performed.

[how to use]
When the blood collection table 10 is used, a part of the body of the blood sample, such as the lower arm, is placed on the upper surface of the elastic deformation member 21 covered with the belt-like sheet 12. Then, blood is collected by a known method using a syringe, a vacuum blood collection tube, or the like. After blood collection, the handle 51 of the second core member 14 is rotated clockwise in FIG. As shown in FIG. 4, when the shaft portion 50 of the second core member 14 rotates in the clockwise direction, the belt-like sheet 12 is wound around the shaft portion 50 while moving in the direction of the arrow 60. Accordingly, the belt-like sheet 12 moves in the direction of the arrow 61 on the upper surface of the elastic deformation member 21. The unused belt-like sheet 12 wound around the shaft portion 40 of the first core member 13 is unwound in the direction of the arrow 62. The second core material 14 is rotated until the belt-like sheet 12 covering the upper surface of the elastic deformation member 21 is completely replaced by the unused belt-like sheet 12 wound around the first core material 13. Then, after replacing the upper surface of the elastic deformation member 21 with the unused belt-like sheet 12, a part of the body of the next blood sample is placed on the upper surface of the elastic deformation member 21 covered with the unused belt-like sheet 12. Placed. Further, the same operation is performed for the next blood sample, and a part of the body of the blood sample is placed on the upper surface of the elastic deformation member 21 always covered with the unused belt-like sheet 12. The

  When all the belt-like sheets 12 wound around the first core material 13 are used, the used belt-like sheet 12 is wound around the second core material 14. Then, the first core member 13 and the second core member 14 are removed from the support base 11 as described above.

Since it is unwound to the upper surface of 21, a part of the body of each blood sample is always supported on the new belt-like sheet 12. Therefore, a sanitary blood collection table 10 is realized. Moreover, since the strip | belt-shaped sheet | seat 12 can be continuously replaced | exchanged when the 2nd core material 14 is rotated, rapid blood collection is implement | achieved at low cost.

  Moreover, since the 1st core material 13 and the 2nd core material 14 can be attached or detached with respect to the support stand 11, after using all the strip | belt-shaped sheets 12 wound by the 1st core material 13, the new strip | belt-shaped sheet | seat 12 is wound. If the first core member 13 and the second core member 14 are replaced with each other, the support base 11 can be reused. The first core material 13 and the second core material 14 after use can be reused by winding or connecting a new belt-like sheet 12.

  In the present embodiment, the first core member 13 and the second core member 14 can be attached to and detached from the support base 11 by removing the handles 41 and 51 from the shaft portions 40 and 50, respectively. Needless to say, this attachment / detachment structure is not limited to the mode shown in the present embodiment, and other configurations may be employed. Further, the shaft portion 40 of the first core member 13 and the shaft portion 50 of the second core member 14 do not necessarily need to be replaced integrally with the respective handles 41 and 51. For example, if the new belt-like sheet 12 is wound around another shaft 40, the handle 41 is reused, and only the shaft 40 around which the new belt-like sheet 12 is wound is used. The unit 40 may be replaced. Moreover, the position and rotation direction of the 1st core material 13 and the 2nd core material 14 in this embodiment are relative, and the position in the support stand 11, and the rotation direction for unwinding or winding are changed suitably. May be.

  In addition, the handle 51 that rotates together with the shaft portion 50 is provided at one end of the second core member 14, thereby improving the operability when the second core member 14 is rotated manually.

  Further, by making the support surface of the support base 11 a part of the elastic deformation member 21, a soft feeling with less pain can be given to a part of the body to be supported.

  Further, since the elastic deformation member 21 is supported by the support plate 22 and the support plate 22 is supported at a predetermined height on the work table by the pair of leg portions 23 and 24, the first core member 13 and The second core member 14 can be installed on the pair of leg portions 23 and 24 below the support plate 22, and the space below the support plate 22 is formed between the first core member 13, the second core member 14, and the belt-like sheet 12. The blood collection table 10 can be made compact as a storage space.

  In the present embodiment, the support base 11 has a U-shaped base body 20 whose lower side is opened. However, in the present invention, the support base has a shape other than such a U-shape. May be. In this embodiment, the elastic deformation member 21 is a flat plate having a rectangular shape in plan view. However, in the present invention, the elastic deformation member may have another shape such as a flat plate having a trapezoidal shape or a square shape in plan view. . The belt-like sheet may be supplied or drawn in any direction such as the longitudinal direction or the lateral direction with respect to the support surface of such an elastically deformable member.

[Modification]
In the above embodiment, the supply means in the present invention is configured by the first core material 13 and the storage means in the present invention is configured by the second core material 14, but the supply means and the storage means in the present invention are other The following embodiments can be adopted. For example, as shown in FIG. 6, the supply unit may be configured by a first storage space 71, and the storage unit may be configured by a second storage space 72 and roller pairs 73 and 73. In FIG. 6, members denoted by the same reference numerals as those in the above embodiment are the same members.

  In this modified example, the first core member 13 and the second core member 14 are not provided in the support base 11, and instead, they are provided at the lower ends of the pair of leg portions 23 and 24, and the first housing is provided. A bottom plate 75 that forms the bottom surface of the space 71 and the second storage space 72, and is erected from the bottom plate 75 to the support plate 22 so that the space between the support plate 22 and the bottom plate 75 is the first storage space 71 and the second storage space. A partition plate 76 that divides the space 72 is provided on the support base 11. Further, in the second accommodation space 72, two rollers 73 and 74 are rotatably installed between the pair of leg portions 23 and 24 with the horizontal direction as the axial direction.

  The first accommodation space 71 accommodates the belt-like sheet 12 placed on the bottom plate 75 and folded in a laminated state. The first accommodation space 71 has an opening on the small face side (the arrow 36 side in FIG. 6) of the support plate 22, and the belt-like sheet 12 extends from the opening to the upper surface of the elastic deformation member 21.

  The second housing space 72 is open on the small face side (the arrow 25 side in FIG. 6) of the support plate 22. Two rollers 73 and 74 are arranged near the opening and near the lower surface of the support plate 22. The rollers 73 and 74 are close to each other with a space slightly narrower than the thickness of the belt-like sheet 12 between the roller surfaces. Although not shown in FIG. 6, a handle is provided at at least one end of the rollers 73 and 74 as in the case of the first core material 13 and the second core material 14 described above. Is rotated, the roller 73 or the roller 74 is rotated. A space that can be accommodated in a state in which the belt-like sheet 12 is folded is formed in the second accommodation space 72 behind the rollers 73 and 74 (partition plate 76 side).

  The belt-like sheet 12 extending from the first accommodation space 71 covers the upper surface of the elastic deformation member 21 and reaches the second accommodation space 72. Then, it is sandwiched between the pair of rollers 73 and 74 and reaches the inner part of the second accommodation space 72. The pair of rollers 72 and 74 are held in pressure contact with the belt-like sheet 12. By this pressure contact, the rotation of the roller 73 or the roller 74 is transmitted to the belt-like sheet 12. When the roller 73 or the roller 74 is rotated after blood collection, the rotation is transmitted and the belt-like sheet 12 is drawn into the second accommodation space 72. The roller 73 or the roller 74 to which no rotational force is applied rotates with the belt-like sheet 12 being drawn. As a result, a part of the belt-like sheet 12 covering the upper surface of the elastic deformation member 21, that is, a part after use is drawn into the second storage space 72 and placed on the bottom plate 75. Along with this, a part of the belt-like sheet 12 accommodated in the first accommodation space 71, that is, an unused part is supplied to the upper surface of the elastic deformation member 21. As a result, as in the above-described embodiment, a part of the body of each blood sample is always supported on the new belt-like sheet 12, so that the sanitary blood collection table 10 is realized. Further, when the roller 73 or the roller 74 is rotated, the belt-like sheet 12 can be continuously replaced, so that rapid blood collection is realized at low cost.

  When all the belt-like sheets 12 accommodated in the first accommodation space 71 are used, all the belt-like sheets 12 are accommodated in the second accommodation space 72. Then, the used belt-like sheet 12 is taken out from the second storage space 72, and a new belt-like sheet 12 in a stacked state is loaded into the first storage space 71. Then, the new belt-like sheet 12 is taken out from the first accommodation space 71 and extended to the upper surface of the elastic deformation member 21 and the second accommodation space 72 and is sandwiched between the rollers 73 and 74. Thereby, the support base 11 is reused similarly to the said embodiment.

  In addition, the combination of the supply means and the accommodation means in this invention is not limited to the combination shown by the said embodiment and modification. Therefore, the first core member 13 may be provided instead of the first storage space 71 in the modified example, and the second core member 14 may be provided instead of the second storage space 72.
