Description

  The present invention relates to a blood collection table that is placed on a table for blood collection and supports the body arm of the blood sampled person, and more particularly to a blood collection table in which a support surface that supports the arm 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 vacuum blood collection tube holder is pierced until it reaches a vein in the arm of the blood collection subject. At that time, a blood collection table is used to stably place the arm through which the blood collection needle is inserted. 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 (for example, Patent Documents 1 to 5).

  In the conventional blood collection table, the member on which the arm of the blood sample is placed is composed of a relatively soft member such as a cushion material, and the support surface that comes into contact with a part of the body in the member such as the cushion material is hygienic. From a general viewpoint, it is covered with a cover material such as cloth (for example, Patent Document 3).

JP 2007-44443 A JP-A-8-266519 JP 2006-187466 A JP 2006-68224 A Utility Model No. 3104383

  For example, a portable and compact blood collection table is suitable for blood collection for medical examinations in the workplace and blood collection in hospital wards. Therefore, relatively large ones such as the blood collection bed shown in Patent Document 1 and the blood collection table with a support table shown in Patent Document 2 are unsuitable.

  In addition, when blood collection is continuously performed from a large number of blood collection subjects in a health examination or the like, a blood collection table may be reused for a plurality of blood collection subjects. In blood collection, blood may be scattered on the blood collection table. Reuse of a blood collection table to 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. Moreover, the operation | work which replaces | covers a cover material for every blood collection is complicated, and a blood collection operation becomes inefficient.

  Patent Document 3 discloses a blood collection table whose cover can be continuously replaced, but it is not clear how the cover after use is handled. If the cover after use is separated and thrown away, the cover after use must be cut and thrown away every time the blood sample is changed, and the work is complicated. Moreover, since the separated cover is bulky, a large-capacity medical trash can is required. Furthermore, in this blood collection table, when replacing the roll cover or the folding cover, the upper member of the blood collection table is removed or the blood collection table is turned over. The operation of removing the upper member of the blood collection table is complicated in the middle of performing a large number of blood collections. Also, if the blood collection table is turned over, the cover that is contaminated by blood and comes into contact with the mounting surface such as a desk is not preferable. In addition, since the new cover comes in contact with the mounting surface such as a desk, it is necessary to replace the portion in contact with the mounting surface when using it, which increases the number of work steps and wastes a part of the cover. Become.

  Further, in the blood collection table placed on the table, as shown in Patent Document 4 and Patent Document 5, the support surface for supporting the arm of the blood sample is inclined so that the wrist is below the elbow. Yes. A blood collection operator such as a nurse pierces the arm with a blood collection needle from the wrist side of the blood sample. In such a blood collection table, a space that can be formed below the support surface is limited in order to preferentially adopt the height and inclination angle of the support surface suitable for blood collection. Further, it is not preferable that the cover material after use is exposed to the blood sampled side.

  The present invention has been made in view of these circumstances, and an object of the present invention is to be able to continuously replace the sheet covering the support surface and to easily and hygienically replace the sheet roll. It is to provide a small blood collection table.

  Another object of the present invention is that the support surface can support the arm of the blood sample in a posture with the wrist below the elbow, and a sheet roll and a used sheet are stored hygienically below the support surface. It is to provide a small blood collection table.

(1) A blood collection table according to the present invention comprises a support table having a support surface that can support the blood collection person's arm in a state of being placed on a table, and a belt-like sheet covering the support surface is wound in a roll shape. A sheet storage roll, a roll storage section that is provided at a first end side facing the blood collection person on the support base and below the support surface, and stores the sheet from the sheet roll so that the sheet can be pulled out; A sheet take-up unit that is provided on a second end side opposite to the first end of the support base and is provided below the support surface and winds up a sheet covering the support surface. The support base includes a support plate having the support surface and leg portions extending downward from the support plate. The sheet winding portion is provided on a leg portion of the support base , and is fitted into a bearing groove that opens to the second end and extends toward the first end, and is rotatably fitted in the bearing groove. A rotating shaft connected to the seat, and a lock member provided in the bearing groove for positioning the rotating shaft with respect to the opening side.

  The blood collection table according to the present invention is used by being placed on a table. The tabletop means a worktable or a tabletop for collecting blood. The blood collection table placed on the table supports the arm of the blood collection subject during blood collection. The support surface that supports the arm 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 accommodated in the roll accommodating portion as a sheet roll wound in a roll shape. The roll accommodating portion is provided below the support surface on the first end side of the support base. The sheet pulled out from the roll accommodating portion covers the support surface and extends from the first end to the second end. The first end and the second end are opposite ends of the support table, and the blood collection table is used in a posture in which the first end faces the blood collection subject. The longitudinal direction of the belt-like sheet is along the direction extending from the first end to the second end. A nurse or the like usually collects blood from a position facing the second end. For example, if the support surface is rectangular, both ends in the long side direction of the support surface correspond to the first end and the second end. And the longitudinal direction of a sheet | seat is extended along the long side of a support surface, and covers a support surface. The sheet covering the support surface is wound on the sheet winding unit on the second end side. Since the sheet winding unit is provided on the second end side that does not face the blood sample, the used sheet is not exposed to the blood sample.

The sheet take-up portion has a rotating shaft rotatably fitted in a bearing groove provided in a leg portion of the support base , and the rotating shaft is positioned by a lock member. The rotating shaft does not necessarily need to be supported rotatably only by the bearing groove, and the rotating shaft may be supported rotatably by the bearing groove and the lock member. Since the bearing groove opens at the second end of the support base below the support surface, the rotating shaft to which the sheet is connected can be inserted into the bearing groove without turning the support base upside down. Moreover, since the roll accommodating portion and the sheet winding portion are provided below the support surface, it is not necessary to extend the support base outward from the first end and the second end.

  When the blood collection table is used, the blood collection person's arm is supported on the support surface covered with the sheet. And after blood collection, the sheet | seat which covers a support surface is wound up by a sheet | seat winding part. The winding of the sheet is based on the rotation of the rotating shaft, but the rotating shaft may be manually rotated or may be rotated by driving transmission from a motor or the like. Along with the winding of the sheet, an unused portion of the sheet is supplied from the roll accommodating portion to the support surface to cover the support surface. Therefore, the blood collection person's arm is always supported by the support surface covered with a new sheet. In addition, when the sheet winding unit winds the sheet, even if a force in the direction toward the opening of the bearing groove is applied to the rotating shaft through the sheet, the lock member positions the rotating shaft in the bearing groove. The shaft does not come off the bearing groove.

  (2) The support surface may be an inclined surface that descends from the first end toward the second end.

  Thus, the arm of the blood sample can be supported on the support surface in a posture with the wrist below the elbow.

  (3) The lock member is provided at the back of the bearing groove and is rotatably provided between the first rotation position and the second rotation position, and the rotation shaft is rotatably supported in the inner space thereof. In addition, it may be a cylindrical member having an introduction groove in which the inner space and the bearing groove are continuous at either one of the first rotation position and the second rotation position.

  The rotating shaft inserted into the bearing groove enters the inner space of the cylindrical member through the introduction groove at the back of the bearing groove. Thus, the rotation position where the rotation shaft can enter the bearing groove from the bearing groove is either the first rotation position or the second rotation position. When the cylindrical member is rotated to the other of the first rotation position or the second rotation position in the inner part of the bearing groove, the introduction groove does not continue with the bearing groove, so that the rotation shaft is rotatably supported in the inner space of the cylindrical member. However, it does not move from the inner space to the bearing groove. Thereby, a rotating shaft is positioned with respect to the opening side of a bearing groove.

  (4) You may further provide the lever extended from the said cylindrical member and rotating the said cylindrical member.

  Since the cylindrical member is easily rotated by this lever, operability is good.

  (5) The roll accommodating portion opens at a first end of the support base, and closes the accommodating space in which the sheet roll can be loaded through the opening, and the slit in which the sheet can be pulled out. And a lid.

  Since the roll accommodating portion opens at the first end of the support base below the support surface, the sheet roll can be loaded into the accommodation space without turning the support base upside down.

  (6) One end of the rotating shaft may protrude to the outside of the support base, and a handle that rotates together with the rotating shaft may be provided at one end thereof.

  Examples of the handle include those that can be held between fingers, such as a dial-shaped one provided at one end of the rotating shaft. This handle improves the operability when manually rotating the rotary shaft. In the present invention, the handle may be provided at at least one end of the rotating shaft, but the handle may be provided at both ends of the rotating shaft.

(7) The support surface may be constituted by an elastically deformable member supported by the support plate, and the bearing groove may be provided on each of the pair of leg portions.

  The elastic deformation member is made of, for example, a sponge or a low-resilience polyurethane. By configuring the support surface with this elastic deformation member, it is possible to give a soft touch with little pain to the arm of the blood sample. 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. The rotating shaft is rotatable with both ends in the axial direction supported by a pair of leg portions, respectively. In other words, the rotation shaft is installed on the pair of leg portions below the support plate. Thereby, the blood collection table can be reduced in size by using the space below the support plate as the accommodation space for the belt-shaped sheet wound around the rotation shaft.

(8) The elastic deformation member may be detachable from the support plate .

  Thus, when blood or the like passes through the sheet and reaches the elastic deformation member, the elastic deformation member can be replaced. Moreover, when an elastic deformation member deteriorates, an elastic deformation member can be replaced | exchanged.

  According to the present invention, since the sheet take-up unit is provided on the second end side of the blood collection table, the used sheet is not exposed to the blood sample, and a sanitary blood collection table is realized.

  Further, since the bearing groove opens at the second end of the support base below the support surface, the rotating shaft to which the sheet is connected can be inserted into the bearing groove without turning the support base upside down. Thereby, the replacement | exchange operation | work of a sheet roll can be performed easily and hygienically.

  In addition, since the roll accommodating portion and the sheet winding portion are provided below the support surface, it is not necessary to extend the support base outward from the first end and the second end, and a small blood collection base is realized.

  In addition, since the used sheet is wound up by the rotation of the rotation shaft, and the unused portion of the sheet is supplied from the roll accommodating portion to the support surface and covers the support surface, the sheets covering the support surface are continuously collected during a plurality of blood collections. Can be exchanged.

  Further, since the support surface is an inclined surface that descends from the first end toward the second end, blood is collected by supporting the blood collection subject's arm on the support surface in a posture with the wrist below the elbow. be able to.

  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 size that can be placed on a work table or a desk on which blood is collected, and a blood collection person's arm is placed on the blood collection table 10 during blood collection. The blood collection table 10 includes a support table 11, a sheet 12, rotary shafts 13 and 14, and lock members 15 and 16 as main members.

[Support 11]
As shown in FIG. 4, 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 includes a support plate 22 serving as a top plate and a pair of leg portions 23 and 24. The support plate 22 is a flat plate that is rectangular in plan view. A pair of legs 23 and 24 extending in the vertical direction are provided on both edges forming a pair of long sides in the support plate 22. The pair of leg portions 23, 24 is provided over each long side of the support plate 22. The support plate 22 and the leg portions 23 and 24 are integrally formed as one member. The pair of leg portions 23, 24 protrude in the vertical direction from both edges that are the long sides of the support plate 22. The support plate 22 is supported at a predetermined height from the upper surface of the work table or the like by the pair of leg portions 23 and 24. As shown in FIG. 7, the lower side of the support plate 22 is a space for accommodating the sheet roll 17.

  In a state where the support base 11 is placed on the work table, the support plate 22 is inclined along the long side direction. An end on the support plate 22 that is inclined upward is referred to as a first end 25 in this specification. An end that faces the first end 25 and is inclined downward is referred to as a second end 26 in the present specification. That is, the upper surface of the support plate 22 is an inclined surface that descends from the first end 25 toward the second end 26 along the long side direction. In the present specification, each member constituting the support base 11 may also be referred to as the first end 25 side and the second end 26 side, but these are the first end 25 and the second end of the support plate 22. The side where the two ends 26 are located is shown. Although not shown in each figure, if 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, the support base 11 does not slip on the upper surface of the work table or the like, which is preferable. It is.

  Although the magnitude | size of the support stand 11 is not specifically limited, It sets to the magnitude | size suitable for blood collection. Further, considering the carrying of the blood collection table 10 and the like, it is preferable that the size is small. Furthermore, the space below the support plate 22 is set so as to accommodate the sheet roll 17 having a length suitable for the number of blood collecting persons and the wound sheet 12. The inclination of the support plate 22 is set at an angle suitable for the blood sample to place the arm on the elastic deformation member 21 with the wrist below the elbow. For example, if the sheet 12 is exchanged for every 100 blood samples, the diameter of a general cloth sheet roll 17 is about 65 mm when a paper tube 79 having a diameter of 25 mm (see FIG. 7) is included. Then, considering the accommodation of the sheet roll 17 and the convenience of blood collection work, the height of the support plate 22 at the first end 25 of the support base 11 is about 130 mm from the desktop, and the support plate at the second end 26 of the support base 11 As an example, the height of 22 is about 80 mm from the desktop.

  On the first end 25 side of the leg portions 23 and 24, shaft holes 27 and 28 for rotatably supporting shafts 46 and 47 (see FIG. 8) of the lid 42 described later are provided, respectively. In FIG. 4, the shaft hole 27 formed in the leg portion 23 does not appear, but the shaft hole 27 has a symmetrical shape with the shaft hole 28. The shaft holes 27 and 28 respectively penetrate the leg portions 23 and 24 in the thickness direction, and the respective axis lines are on the same imaginary straight line. The shafts 46 and 47 are fitted into the shaft holes 27 and 28, respectively, so that the lid 42 can be opened and closed.

  On the second end 26 side of the leg portions 23 and 24, bearing grooves 29 and 30 for rotatably supporting rotating shafts 13 and 14 to be described later are provided, respectively. The bearing grooves 29 and 30 have slit shapes penetrating the leg portions 23 and 24 in the thickness direction. The bearing grooves 29 and 30 are opened to the second end 26 side of the leg portions 23 and 24 below the support plate 22 and extend in the horizontal direction toward the first end 25 side. The openings of the bearing grooves 29 and 30 are arranged at a height position that is the center of the lower part of the leg portions 23 and 24 from the support plate 22. The width in the vertical direction in the vicinity of the openings of the bearing grooves 29 and 30 is substantially the same as the outer diameter of the small diameter portion 74 (see FIG. 5) of the rotary shafts 13 and 14. In addition, lock bearing portions 31 and 32 having an inner diameter larger than the width in the vicinity of the opening are provided at the back of each bearing groove 29 and 30 (on the side opposite to the opening). In FIG. 4, the lock receiving portion 31 formed on the leg portion 23 does not appear, but the lock receiving portion 31 is symmetrical with the lock receiving portion 32. The axis lines of the lock receiving portions 31 and 32 coincide with each other. Lock members 15 and 16 are rotatably fitted in the lock receiving portions 31 and 32, respectively.

  As shown in FIG. 4, exterior materials 33 and 34 are provided outside the leg portions 23 and 24. Each of the exterior members 33 and 34 has a shape that covers all the outer surfaces of the leg portions 23 and 24. Accordingly, the corresponding leg portions 23 and 24 and the exterior materials 33 and 34 have the same shape in a side view (see FIG. 6). Bearing grooves 35 and 36 are formed in the respective exterior members 33 and 34 so as to correspond to the bearing grooves 29 and 30 of the leg portions 23 and 24. The bearing grooves 35 and 36 are integrated with the bearing grooves 23 and 24 in a state where the exterior members 33 and 34 are provided in the corresponding leg portions 23 and 24. Therefore, since the shape of the bearing grooves 35 and 36 is the same as the shape of the bearing grooves 23 and 24 described above, detailed description is omitted here.

  As shown in FIG. 4, guide grooves 37 and 38 extending in an arc from the bearing grooves 35 and 36 are formed on the outer surfaces of the exterior members 33 and 34, respectively. The guide grooves 37 and 38 are fitted with projections 69 (see FIG. 9) of the lock members 15 and 16, which will be described later. The guide grooves 37 and 38 are grooves recessed from the outer surfaces of the respective exterior members 33 and 34. In FIG. 4, the outer surface of the exterior material 33 does not appear, and a guide groove 37 that bulges on the back surface facing the leg portion 23 appears in the exterior material 33, but this guide groove 37 is formed by the exterior material 33. Is recessed on the outer surface of The extending direction of each guide groove 37, 38 is an arc centered on the back of the bearing groove 35, 36. Each guide groove 37, 38 extends from the bearing groove 35, 36 to a position directly above the interior of each bearing groove 35, 36, respectively. The extending ends of the guide grooves 37 and 38 form a hemispherical surface 39 in which the depth in the concave direction (thickness direction) is further deepened. In FIG. 4, the hemispherical surface of the guide groove 37 does not appear, but has the same shape as the hemispherical surface 39. Due to the hemispherical surface 39, the protrusions 69 of the lock members 15 and 16 are fixed to the extending ends of the guide grooves 37 and 38, and the levers 62 and 63 have a click feeling when the protrusion 69 enters and exits the extending ends. Occurs.

  As shown in FIG. 4, the elastic deformation member 21 is detachably fixed to the upper surface of the support plate 22. The elastic deformation member 21 is a flat plate having a rectangular shape in plan view, and has an outer dimension substantially equal to the outer dimension 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 elastic deformation member 21 is fixed to the upper surface of the support plate 22 so that both ends (small face surfaces) in the long side direction are aligned with the first end 25 and the second end 26 of the support plate 22. Although not shown in the figure, the elastic deformation member 21 and the support plate 22 are connected by a hook-and-loop fastener, and the elastic deformation member 12 can be attached to and detached from the support plate 22. The upper surface of the elastic deformation member 21 fixed to the support plate 22 serves as a support surface capable of supporting the blood collection subject's arm during blood collection. The thickness of the elastic deformation member 21 is constant with respect to the long side direction, and the upper surface of the elastic deformation member 21 is inclined along the upper surface of the support plate 22.

  As shown in FIG. 7, the upper surface, that is, the support surface of the elastic deformation member 21 is covered with the sheet 12. The sheet 12 is a flat belt made of, for example, cloth, paper, or other material that can absorb blood. The width of the sheet 12 is equal to the length of the elastic deformation member 21 in the short side direction. The length of the sheet 12 is sufficiently longer than the length of the elastic deformation member 21 in the long side direction. Therefore, the sheet 12 can substantially cover the upper surface of the elastic deformation member 21. The sheet 12 is wound into a cylindrical shape around the width direction as a sheet roll 17. The sheet 12 is pulled out from the sheet roll 17 to cover the upper surface of the elastic deformation member 21.

[Roll accommodating part 40]
As shown in FIGS. 2 and 3, a roll accommodating portion 40 is provided on the first end 25 side of the support base 11. As shown in FIG. 7, the roll accommodating portion 40 accommodates the sheet roll 17. The roll accommodating portion 40 mainly includes a partition wall 41 and a lid 42 suspended from the support plate 22.

  As shown in FIG. 7, the partition wall 41 extends downward from a position inside the first end 25 on the lower surface of the support plate 22, and the extending end is curved toward the first end 25. . As shown in FIG. 3, the width of the partition wall 41 is approximately the same as the width of the support plate 22. The curvature of the extending end of the partition wall 41 is set in consideration of the diameter of the sheet roll 17. A space closer to the first end 25 of the support plate 22 than the partition wall 41 is an accommodation space 55 for accommodating the sheet roll 17. The accommodation space 55 is open to the first end 25 side of the support plate 22. The partition wall 41 substantially separates the accommodation space 55 below the support plate 22 and the space on the bearing grooves 29 and 35 side.

  As shown in FIGS. 2 and 7, the lid 42 extends from the vicinity of the extending end of the partition wall 41 toward the first end 25 of the support plate 22. The lid 42 opens and closes the opening of the accommodation space 55. As shown in FIG. 8, the lid 42 has a curved plate 43 as a main component. As shown in FIGS. 2 and 3, the curved plate 43 has a width approximately the same as the width of the support plate 22, and the height thereof is lower than the support plate 22 among the leg portions 23 and 24 of the base body 20. It is slightly lower than the part.

  As shown in FIG. 8, side plates 44 and 45 are provided on both sides of the curved plate 43. The side plates 44 and 45 protrude from the curved plate 43 toward the accommodation space 55 (inner side of the curve). Each of the side plates 44 and 45 has a protruding width that increases downward along both sides of the curved plate 43, and the lowermost end has a semicircular shape. In the vicinity of the lowermost end of each side plate 44, 45, shafts 46, 47 projecting outward from the curved plate 43 are provided. The shafts 46 and 47 are inserted into shaft holes 27 and 28 (see FIG. 4) provided in the pair of leg portions 23 and 24 of the base body 20, and the lid 42 is rotatably supported by the base body 20. . In the vicinity of the upper ends of the side plates 44 and 45, pins 52 and 53 that protrude toward the outside of the curved plate 43 are provided. As shown in FIG. 3, when the pins 52 and 53 are fitted in the recessed portions 57 and 58 provided in the pair of leg portions 23 and 24, the lid 42 is held in the closed posture (see FIG. 2). The In FIG. 3, the recessed portion 58 does not appear, but the recessed portion 58 has a symmetrical shape with the recessed portion 57.

  As shown in FIG. 8, the curved plate 43 is provided with ribs 49 to 51 having substantially the same shape as the side plates 44 and 45 in parallel between the side plates 44 and 45. The ribs 49 to 51 protrude from the curved plate 43 toward the accommodation space 55. The ribs 49 to 51 reinforce the curved plate 53 and the end surface protruding into the accommodation space 55 positions the sheet roll 17.

  As shown in FIG. 8, the curved plate 43 is provided with a through hole 54 that penetrates in the thickness direction. The through hole 54 is disposed in the center of the curved plate 43 in the width direction and in the vicinity of the upper end. The through-hole 54 has a size that allows a finger of a blood collecting person to be inserted. The lid 42 in the closed position can be rotated to the open position (see FIG. 3) by placing a finger on the through hole 54. Moreover, the state of the sheet roll 17 accommodated in the roll accommodating portion 40 can be visually recognized from the outside of the lid 42 in the closed posture.

  As shown in FIGS. 2 and 3, the lid 42 can be rotated with respect to the base body 20 by assembling the lid 42 described above to the base body 20. As shown in FIG. 2, a state in which the upper end (rotating tip) of the lid 42 is positioned near the first end 25 of the support plate 22 is referred to as a closed posture of the lid 42 in this specification.

A knob 68 is provided on the outer surface of the leg portion 23 of the lever 62. The knob 68 has a thin rib shape, and is large enough to allow a person who collects blood to hold it between fingers. A protrusion 69 is provided on a surface of the lever 62 facing the leg portion 23. The protrusion 69 has a hemispherical shape, and the diameter of the protrusion 69 is slightly shorter than the width of the bearing grooves 29 and 35. The protrusion 69 is fitted into the guide groove 37 formed in the exterior material 33 in a state where the cylindrical member 60 is fitted in the bearing grooves 29 and 35.

  The cylindrical member 60 that is rotatably fitted in the bearing grooves 29 and 35 is allowed to rotate by 90 degrees by the fitting of the protrusion 69 of the lever 62 and the guide groove 37. As shown in FIGS. 1 and 7, the rotational position of the locking member 15 in which the protrusion 69 enters the bearing grooves 29 and 35 and the lever 62 extends in the horizontal direction is referred to as a first rotational position in this specification.

Therefore, the rotating shaft 13 that has entered the inner space of the cylindrical member 60 is positioned with respect to the opening side of the bearing grooves 29 and 35 and is rotatably supported by the bearing grooves 29 and 35 and the cylindrical member 60.

  As shown in FIG. 5, when the lever 62 rises in the vertical direction toward the arrow 104, the cylindrical member 60 at the first rotation position is also rotated to the arrow 104. At this time, the protrusion 69 of the lever 62 moves along the guide groove 37 to the extending end of the guide groove 37 (see FIG. 4). When the lever 62 rises in the vertical direction, the protrusion 69 is fitted and fixed to the extending end of the guide groove 37. At this time, the lever 62 has a click feeling. The rotational position of the lock member 15 where the lever 62 stands in the vertical direction is referred to as a second rotational position in this specification. Even when the lever 62 standing in the vertical direction is laid down in the horizontal direction, the protrusion 69 is detached from the extending end of the guide groove 37, and the lever 62 has a click feeling.

  In the second rotation position, the introduction groove 67 continues to the bearing grooves 29 and 35 in the horizontal direction toward the second end 26. Therefore, the rotating shaft 13 can be made to enter the inner space of the cylindrical member 60 from the bearing grooves 29 and 35, and the rotating shaft 13 can be moved from the inner space of the cylindrical member 60 to the openings of the bearing grooves 29 and 35. it can.

As shown in FIG. 5, the rotary shafts 13 and 14 have shaft portions 70 and 71 and handles 72 and 73, respectively. The rotating shafts 13 and 14 have the same shape except that they are fitted into the bearing grooves 29 and 35 or the bearing grooves 30 and 36. Therefore, the rotating shaft 13 will be described in detail below as an example. A detailed description of the shaft 14 is omitted.

  The rotating shaft 13 includes a shaft portion 70 and a handle 72. A small diameter portion 74 is provided on the handle 72 side of the shaft portion 70. The length of the small diameter portion 74 in the axial direction is approximately the same as the thickness of the leg portion 23 and the exterior material 33. The outer diameter of the small diameter portion 74 is large enough to enter the bearing grooves 29 and 35, and is large enough to enter the inner space of the cylindrical member 60 through the introduction groove 67 with respect to the lock member 15.

  A flange 75 is provided on the opposite side of the small diameter portion 74 from the handle 72. The side on which the flange 75 is provided with respect to the axial direction of the small diameter portion 74 corresponds to the inside of the leg portion 23. The flange 75 is a disk extending in the radial direction of the small diameter portion 74. When the rotary shaft 13 enters the inner space of the cylindrical member 60, the flange 75 faces the flange 66. A core material connecting portion 76 is provided from the flange 75 in the direction opposite to the handle 72. The core connecting portion 76 is formed by radially providing a plurality of thin ribs 78 extending radially and axially on the outer peripheral surface of a cylindrical core 77 protruding in the axial direction of the small diameter portion 74. The rib 78 of the core material connecting portion 76 is set to a size that is press-fitted into a cylindrical paper tube 79 as an example of the core material. Note that the sheet 12 is not necessarily connected to the core material connecting portion 76 via the core material, and may be directly connected to the core material connecting portion 76.

  The handle 72 is provided on the opposite side of the flange 75 with respect to the small diameter portion 74. The side where the handle 72 is provided with respect to the axial direction of the small diameter portion 74 corresponds to the outside of the leg portion 23.

The sheet 12 extended to the bottom is extended below the elastic deformation member 21 at the second end 26 and connected to a paper tube 79 attached to the shaft portions 70 and 71 of the rotary shafts 13 and 14. The width direction of the sheet 12 thus extended matches the short side direction of the elastic deformation member 21 and also matches the axial direction of the rotary shafts 13 and 14.

[How to use blood collection table 10]
The blood collection table 10 is placed on a table and used for blood collection, and is particularly suitable for blood collection performed continuously from a large number of people as in a health examination. At the time of blood collection, an unused sheet roll 17 is loaded into the roll accommodating portion 40 of the blood collection table 10. When the sheet roll 17 is loaded, the blood collection table 10 is placed on the work table or the like with the support plate 22 supported at a predetermined height from the upper surface of the work table or the like by the legs 23 and 24, as shown in FIG. Placed.

  As shown in FIG. 2, a finger is put on the through hole 54 of the lid 42 to bring the lid 42 into an open posture, and the roller accommodating portion 40 is opened. Then, the unused sheet roll 17 is inserted into the roller accommodating portion 40 with the horizontal direction as the axial direction. The end of the sheet 12 on the outer periphery of the inserted sheet roll 17 is gripped and pulled out from the rotating tip of the lid 42. When the lid 42 is in the closed posture, as shown in FIG. 7, the sheet roll 17 is supported in the horizontal direction along the first end 25 of the support plate 22 by the partition wall 41 and the ribs 48 to 51. The sheet 12 pulled out from the sheet roll 17 extends to the outside of the roll accommodating portion 40 through the slit 56.

  The sheet 12 extending from the slit 56 is further pulled out so as to extend from the first end 25 side to the second end 26 side along the upper surface of the elastic deformation member 21. The sheet 12 is pulled out in the longitudinal direction of the band shape. The rotating shafts 13 and 14 are fitted with cylindrical paper tubes 79 on the shaft portions 70 and 71 in a state where the rotating shafts 13 and 14 are not fitted into the bearing grooves 29, 30, 35 and 36. Then, the end of the sheet 12 is connected to the paper tube 79 attached to the shaft portions 70 and 71. The paper tube 79 attached to the shaft portions 70 and 71 is an example of a core material, and a core material other than the paper tube 79 such as a plastic tube may be used.

  The levers 62 and 63 of the lock members 15 and 16 are respectively rotated and held at the second rotational position, and the above-described rotary shafts 13 and 14 are inserted into the bearing grooves 29, 30, 35 and 36. At this time, care should be taken that the sheet 12 covers the upper surface of the elastic deformation member 21 without twisting. Then, the rotary shafts 13 and 14 are caused to enter the interior of the bearing grooves 29, 30, 35 and 36, and further the rotary shafts 13 and 14 are caused to enter the inner space of the cylindrical members 60 and 61 through the introduction groove 67. Thereafter, the levers 62 and 63 of the lock members 15 and 16 are respectively rotated to the first rotation position, thereby positioning the rotation shafts 13 and 14 with respect to the openings of the bearing grooves 29, 30, 35 and 36. Then, by rotating the shaft portions 70 and 71 by holding the handles 72 and 73 of the rotary shafts 13 and 14, the sheet 12 is slightly wound around the paper tube 79 attached to the shaft portions 70 and 71, and the sheet 12 covers the upper surface of the elastic deformation member 21 without slack.

  As described above, the arm of the blood sample is placed on the upper surface of the elastic deformation member 21 covered with the sheet 12. The blood collection table 10 makes the first end 25 of the support plate 22 face the blood collection subject. Thereby, along the inclination of the upper surface of the elastic deformation member 21, the wrist of the blood collection subject has the wrist below the elbow. Then, blood is collected by a known method using a syringe, a vacuum blood collection tube, or the like.

  When the blood collection is finished and the arm of the blood sample is separated from the elastic deformation member 21, the handles 72 and 73 of the rotation shafts 13 and 14 are rotated in the rotation direction for winding the sheet 12. As shown in FIG. 7, the sheet 12 is wound around the paper tube 79 attached to the shaft portions 70 and 71 while moving to the arrow 105 by the rotation of the rotation shafts 13 and 14. Accordingly, the sheet 12 moves to the arrow 105 on the upper surface of the elastic deformation member 21. Further, the unused sheet 12 is pulled out from the sheet roll 17 to the elastic deformation member 21 through the slit 56. At this time, the bearing grooves 29, 30, and 29 are formed on the rotary shafts 13 and 14 through the sheet 12 by sliding friction between the sheet 12 and the elastic deformation member 21, sliding friction between the sheet roll 17, the partition wall 41 and the ribs 48 to 51. Although the force pulled to the opening side of 35 and 36 acts, as mentioned above, the rotating shafts 13 and 14 are formed in the bearing grooves 29, 30, 35, and 36 by the lock members 15 and 16 in the first rotation posture. Since it is positioned with respect to the opening, the pivot shafts 13 and 14 do not move toward the opening.

  The rotating shafts 13 and 14 are rotated until the sheet 12 covering the upper surface of the elastic deformation member 21 is completely replaced by the unused sheet 12 drawn from the sheet roll 17. Then, after replacing the upper surface of the elastic deformation member 21 with the unused sheet 12, the arm of the next blood sample is placed on the upper surface of the elastic deformation member 21 covered with the unused sheet 12. Further, the same operation is performed for the next blood sample, and the arm of the blood sample is always placed on the upper surface of the elastic deformation member 21 covered with the unused sheet 12.

  When all the sheets 12 wound as the sheet roll 17 are pulled out, all the used sheets 12 are wound on the rotary shafts 13 and 14. Then, the levers 62 and 63 of the lock members 15 and 16 are respectively rotated and held at the second rotational position, and the rotary shafts 13 and 14 described above are removed from the bearing grooves 29, 30, 35 and 36. Then, the used sheet 12 is removed from the rotary shafts 13 and 14 together with the paper tube 79 and discarded. When removing the rotary shafts 13 and 14, it is not necessary to turn the support base 11 upside down.

  Thereafter, in the same manner as described above, a new unused sheet roll 17 is loaded into the roll accommodating portion 40, the end of the sheet 12 is connected to a new paper tube 79 mounted on the rotary shafts 13 and 14, and the rotation is performed. The shafts 13, 14 are inserted into the rotary shafts 13, 14 behind the bearing grooves 29, 30, 35, 36. By repeating this, the sheet 12 covering the elastic deformation member 21 can be continuously exchanged until one sheet roll 17 is used up.

  The sheet 12 after use and the paper tube 79 as a core material may be repeatedly used by being washed or sterilized, but are preferably disposable from the viewpoint of hygiene and prevention of infection. . Moreover, the rotating shafts 13 and 14 from which the used sheet 12 is removed may be used as a disposal.

  Further, since the bearing grooves 29, 30, 35, 36 open to the second end 26 below the support plate 22, the rotary shafts 13, 14 to which the seat 12 is connected can be connected without turning the support base 11 upside down. It can be inserted into the bearing grooves 29, 30, 35, 36. Thereby, the exchange operation | work of the sheet | seat roll 17 can be performed easily and hygienically.

  Further, since the sheet winding unit 18 and the roll accommodating unit 40 are provided below the support plate 22, there is no need to extend the support base 11 outward from the first end 25 and the second end 26, and the elastic deformation member A small blood collection table 10 having a mounting area comparable to the area of the upper surface of 21 is realized.

  In addition, since the used sheet 12 is wound up by the rotation of the rotary shafts 13 and 14 and the unused portion of the sheet 12 is supplied from the roll accommodating portion 40 to the elastic deformation member 21 and covers the upper surface thereof, blood sampling for a large number of people At this time, the sheet 12 covering the upper surface of the elastic deformation member 21 can be continuously replaced.

  Even when a force in a direction toward the opening of the bearing grooves 29, 30, 35, 36 is applied to the rotation shafts 13, 14 through the sheet 12 when the sheet 12 is wound by the rotation of the rotation shafts 13, 14, the lock members 15, 16 positions the rotary shafts 13 and 14 in the bearing grooves 29, 30, 35 and 36, so that the rotary shafts 13 and 14 do not come off the bearing grooves 29, 30, 35 and 36.

  Further, since the upper surface of the elastic deformation member 21 is an inclined surface that descends from the first end 25 toward the second end 26, the arm of the blood sample is placed on the elastic deformation member 21 in a posture with the wrist below the elbow. Blood can be collected with support from the upper surface.

  Further, since the lock members 15 and 16 are provided with the levers 62 and 63 for rotating the cylindrical members 60 and 61, by operating the levers 62 and 63, the cylindrical members 60 and 61 can be easily moved to the first rotation posture or It can be rotated to the second rotation posture, and operability is good.

  Moreover, since the accommodation space 55 of the roll accommodating part 40 opens toward the 1st end 25 side under the support plate 22 by making the cover 42 into an open posture, the sheet roll is not turned over. 17 can be loaded into the storage space 55.

  Further, since the rotary shafts 13 and 14 are provided with the handles 72 and 73 protruding to the outside of the support base 11, the operability when the rotary shafts 13 and 14 are manually rotated is improved.

  Further, since the support surface for supporting the arm of the blood sample is constituted by the elastic deformation member 21, it is possible to give a soft feel with little pain to the arm of the blood sample.

  Further, 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 blood collection table or the like by the pair of leg portions 23 and 24. The blood collection table 10 can be downsized by utilizing this space as a space for storing the sheet 12 wound around the rotary shafts 13 and 14 and a storage space 55 for the sheet roll 17.

  Further, since the elastic deformation member 21 can be attached to and detached from the support plate 22 of the base body 20, for example, when blood or the like passes through the sheet 12 and reaches the elastic deformation member 21, the elastic deformation member 21 is replaced. can do. Moreover, when the elastic deformation member 21 deteriorates, the elastic deformation member 21 can be replaced.
