Description

[Technical field]

[0001] The present invention relates to a connection structure for a blood sampling device. [Background technology]

[0002] Conventionally, blood collection devices have been known that are used to mix collected blood with an anticoagulant in a blood bag when collecting blood. This type of blood collection device may be mounted on a moving vehicle (mobile object) such as a blood donation bus and used.

[0003] When mounting a blood collection device on a moving body, since there is a limit to the space inside the moving body, the blood collection device is generally housed in a cage provided at the installation site of the moving body and fixed to the cage by screws, etc. Patent Document 1 proposes a blood collection device equipped with an attachment / detachment mechanism that enables easy attachment / detachment to a base portion fixed to the installation site of the moving body. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2020-199104 A Summary of the Invention [Problem to be solved by the invention]

[0005] When the blood collection device is mounted on a moving body, various vibrations are applied to the connection between the blood collection device and the moving body from the moving body. Therefore, in the moving body, the blood collection device is likely to break down due to vibrations, including the attachment / detachment mechanism as in Patent Document 1. Furthermore, since there are significant restrictions on the space required for disposing the blood sampling device and on the working space required for attaching and detaching the blood sampling device within the movable body, it is desired that the connecting structure for the blood sampling device be of a compact configuration.

[0006] Therefore, the present invention has been made in consideration of the above-mentioned circumstances, and aims to provide a connecting structure for a blood sampling device that can suppress malfunctions such as breakdowns caused by external vibrations and can be stored compactly. [Means for solving the problem]

[0007] One aspect of the present invention is a connection structure for a blood collection device for connecting a blood collection device that collects blood of a donor into a blood bag to an installation part. The installation part has a bottom part facing the bottom of the blood collection device. The connection structure includes a first mount part arranged on the bottom side of the blood collection device and a second mount part arranged on the bottom side of the installation part and connected to the first mount part. The first mount part and the second mount part each have a first connection part arranged on the front side of the installation part and connecting the first mount part and the second mount part with a first bolt inserted in a first direction, and a second connection part arranged on the rear side opposite to the front side of the installation part and connecting the first mount part and the second mount part with a second bolt inserted along a second direction intersecting with the first direction. The first direction and the second direction are each selected from a direction parallel to a horizontal plane or a direction inclined downward with respect to the horizontal plane. The first bolt of the first connecting portion and the second bolt of the second connecting portion are disposed between the first mounting portion and the second mounting portion, and are each screwed into a bolt receiver having an elastically deformable buffer portion. Effect of the Invention

[0008] According to one aspect of the present invention, it is possible to provide a connection structure for a blood sampling device that can suppress problems such as breakdowns caused by external vibrations and can be stored compactly. [Brief description of the drawings]

[0010] Hereinafter, an example of the configuration of the connection structure of the blood collection device according to the embodiment will be described with reference to the drawings. Note that the shapes and dimensions of each part in the drawings are shown only for illustrative purposes and do not represent the actual shapes and dimensions.

[0011] 1 to 3, an XYZ coordinate system is appropriately shown as a three-dimensional Cartesian coordinate system. In the XYZ coordinate system, the Z direction is parallel to the height direction of the blood collection device and the cage body, which will be described later. The X direction is perpendicular to the Z direction and corresponds to the width direction of the bottom surface of the blood collection device and the cage body. The Y direction is perpendicular to both the Z direction and the X direction and corresponds to the depth direction of the bottom surface of the blood collection device and the cage body.

[0012] Fig. 1 is an exploded view showing an example of a blood sampling device 1 and a basket body 2 of this embodiment. Fig. 2 is a perspective view showing a state in which the blood sampling device 1 of this embodiment is attached to the basket body 2. Fig. 3 is a perspective view from the bottom side of Fig. 2. For simplicity, Figs. 2 and 3 show the basket body 2 in a see-through state by a dashed line.

[0013] The blood collection device 1 is mounted on a mobile vehicle (mobile body) such as a blood donation bus, and is operated in a state in which it is housed in a cage body 2 (also called a bucket). The blood collection device 1 and the cage body 2 are connected via a first fixture 3 and a second fixture 4, which are respectively housed in the cage body 2. The first fixture 3 and the second fixture 4 are connected by a first connector 5 on the front side and a second connector 6 on the back side, as described later.

[0014] The blood collection device 1 is used to mix the collected blood with an anticoagulant that is filled in the blood bag beforehand by shaking the blood bag (not shown) when collecting blood from a donor. The blood collection device 1 includes a housing 11, a top cover 12, and an operation unit 13.

[0015] Housing 11 is in the shape of a box with an open top, and the top side of housing 11 is closed by top lid 12. Top lid 12 is made of, for example, a transparent resin (e.g., acrylic resin, etc.), and is attached to housing 11 by a hinge (not shown) provided on the rear side of the device so as to be openable and closable.

[0016] The suction chamber surrounded by the housing 11 and the top cover 12 contains a tray (not shown) on which a blood bag is placed, a rocking mechanism (not shown) for rocking the tray, and a decompression mechanism (not shown) for reducing the pressure inside the suction chamber. The blood collection device 1 generates a suction pressure (negative pressure) in the suction chamber by driving the decompression mechanism, and collects blood into the blood bag. The blood collection device 1 can control the suction pressure by the decompression mechanism.

[0017] 5 described later, legs 14 are provided on the bottom surface of housing 11, which come into contact with a flat surface when blood collection device 1 is placed flat on the flat surface. Legs 14 are formed in a substantially circular plate shape, and four of them are arranged at intervals in the width direction (X direction) and depth direction (Y direction) of blood collection device 1. In this embodiment, blood collection device 1 is supported by basket body 2 without legs 14 of blood collection device 1 coming into contact with basket body 2. The bottom surface of the housing 11 is formed with a screw hole (not shown) for fixing the first fixture 3.

[0018] The operation unit 13 is composed of, for example, a liquid crystal touch panel, and is disposed on the front side of the device of the housing 11. For example, the user can obtain various information from text information or image information displayed on the screen of the operation unit 13. For example, the screen of the operation unit 13 displays the amount of collected blood or the amount of blood remaining to be collected during blood collection. In addition, the screen of the operation unit 13 displays (color display, etc.) indicating the status such as the blood collection speed. Furthermore, by the user's operation of touching an icon image on the operation unit 13, the operation unit 13 accepts various operations such as starting blood collection and stopping blood collection.

[0019] The input to the blood sampling device 1 is not limited to the above, and may be received by an input device (e.g., a barcode reader) connected via a connection terminal (not shown). Various outputs from the blood sampling device 1 may be performed from a known output device connected via the above connection terminal.

[0020] Basket body 2 is an example of an installation part, and is a rectangular box-like body with the front and top sides open to communicate with the outside, and houses blood collection device 1 inside. Blood collection device 1 is housed in basket body 2 in a state in which operation unit 13 on the front side can be operated from the outside, and upper lid 12 on the top side can be opened and closed from the outside, as shown in Fig. 2.

[0021] The basket body 2 has a bottom surface portion 21 facing the bottom surface of the blood sampling device 1, and peripheral wall portions 22 rising vertically from the sides and rear side of the bottom surface portion 21 relative to the bottom surface portion 21. The bottom surface portion 21 of the basket body 2 is provided with a screw hole (not shown) for fixing the second fixing tool 4.

[0022] A rear opening 23 is formed in the peripheral wall 22 of the basket body 2 on the rear side facing the rear of the blood sampling device 1. The rear opening 23 is provided so that the second connecting portion 6 of the first fixing device 3 and the second fixing device 4 is disposed outside the basket body 2 and an operator can access the second connecting portion 6 from outside the basket body 2.

[0023] Moreover, a flange portion 24 that projects outward from the car body 2 is formed on the upper end side of the peripheral wall portion 22. The flange portion 24 is C-shaped in plan view across both side portions and the back portion of the car body 2. The flange portion 24 is also formed with bolt holes (not shown) for fixing to a fixture (not shown) provided on the moving body, and the car body 2 is fixed to the fixture of the moving body with bolts via the flange portion 24. Therefore, the car body 2 fixed to the fixture of the moving body can be subjected to external vibrations from the moving body.

[0024] The cage body 2 is made of a material (such as SUS) that has sufficient rigidity against vibration and is corrosion-resistant against liquids such as blood and disinfectants. However, the cage body 2 may be made of other materials such as resin as long as it satisfies the above conditions.

[0025] Fig. 4 is a side view showing the state in which the first fixing device 3 is attached to the blood sampling device 1. Fig. 5 is a bottom view showing the state in which the first fixing device 3 is attached to the blood sampling device 1. The first fixing device 3 is an example of a first mounting portion, and is a thin plate-like jig that is placed on the bottom side of the blood sampling device 1. The first fixing device 3 has a main body portion 31 and a connecting base portion 32.

[0026] The shape of the main body 31 of the first fixing device 3 in plan view is a substantially rectangular shape with a depth dimension that corresponds approximately to the depth of the blood collection device 1 and a width dimension that corresponds to the space between the legs 14 of the blood collection device 1. Therefore, the main body 31 can be placed between the legs 14 on the bottom surface of the blood collection device 1 as shown in FIG. 5. Also, the main body 31 has holes 31a for inserting screws at positions corresponding to the screw holes on the bottom surface of the blood collection device 1. Therefore, the first fixing device 3 can be detachably attached to the bottom surface of the blood collection device 1 with screws 33 as shown in FIGS. 4 and 5. Although not particularly limited, the hole 31a of the first fixing device 3 and the screw hole of the blood collection device 1 may be configured so that their positions do not coincide when the mounting direction is different, front and back, or front and back, so that the first fixing device 3 can be screwed in when it is correctly mounted on the blood collection device 1.

[0027] A front-side first connecting piece 34 protruding toward the front side is formed in the center of the front side of the main body 31. A hole 34a used for a first connecting part 5 described later is opened in the front-side first connecting piece 34.

[0028] The connecting base 32 of the first fixing device 3 is erected on the rear side of the main body 31 and stands perpendicular to the main body 31. The connecting base 32 is provided with a pair of rear side first connecting pieces 35 that are bent from both widthwise ends of the connecting base 32 toward the rear side and extend so as to protrude toward the rear side. Each of the rear side first connecting pieces 35 is a rectangular flat plate whose short side is the height direction (Z direction) and whose long side is the depth direction (Y direction). Each of the rear side first connecting pieces 35 has a hole 35a that penetrates the rear side first connecting piece 35 in the width direction (X direction) for use in the second connecting part 6 described later.

[0029] The first fixing device 3 is made of a material that has sufficient rigidity against vibration and is corrosion-resistant against liquids such as blood, disinfectants, etc. As an example, the main body 31, connecting base 32, and rear side first connecting piece 35 of the first fixing device 3 may be integrally formed by bending a metal plate such as SUS.

[0030] Fig. 6 is a side view showing a state in which the second fixing device 4 is attached to the car body 2. Fig. 7 is a cross-sectional view taken along line AA in Fig. 6. The second fixing device 4 is an example of a second mounting portion, and is a thin plate-like jig arranged on the bottom side of the cage body 2, and is arranged inside the cage body 2 between the first fixing device 3 and the bottom portion 21 of the cage body 2. The second fixing device 4 has a main body portion 41 and a rib portion 42.

[0031] The shape of the main body 41 of the second fixing device 4 in plan view is a substantially rectangular shape whose depth and width dimensions correspond to those of the blood sampling device 1. The main body 41 is also formed with openings 43 at positions corresponding to the legs 14 of the blood sampling device 1 to avoid interference with the legs 14. The main body 41 is also formed with holes 41a for inserting screws 46 at positions corresponding to the screw holes in the bottom surface 21 of the basket body 2. Therefore, the second fixing device 4 can be detachably attached to the bottom surface 21 of the basket body 2 from above by screwing.

[0032] When fastening the second fastener 4 to the cage body 2 with screws, it is preferable to carve a female thread into the bottom surface of the cage body 2. In the above case, it is not necessary to provide a nut for receiving the screw 46 on the outside of the bottom surface of the cage body 2, and it is possible to prevent the nut from falling off and being lost due to vibration.

[0033] Furthermore, a front side second connecting piece 44 that protrudes toward the front side is formed in the center of the front side of the main body 41. A hole 44a used for the first connecting part 5 is opened in the front side second connecting piece 44. The front side second connecting piece 44 and the hole 44a of the second fastener 4 are provided at positions corresponding to the front side first connecting piece 34 and the hole 34a of the first fastener 3, respectively.

[0034] The rib portions 42 of the second fixing device 4 are provided opposite each other on both sides near the rear side of the main body portion 41. The rib portions 42 are formed in a rectangular flat plate shape having planes along the height direction (Z direction) and the depth direction (Y direction), and face the inner surface of the peripheral wall portion 22 of the car body 2 when the second fixing device 4 is placed inside the car body 2. Therefore, when the second fixing device 4 is placed inside the car body 2, it becomes possible to sandwich and hold a sheet-like buffer member 7b (for example, a shock absorbing material made of an elastic sheet such as anti-vibration rubber) between the rib portions 42 and the peripheral wall portion 22 of the car body 2, as shown in FIG. 7.

[0035] When the sheet-like buffer member 7b is disposed between the rib portion 42 and the peripheral wall portion 22, the vibration components in the width direction from the moving body are more effectively damped by the compressive deformation of the buffer member 7b. In addition, the vibration components in the depth direction and height direction can also be damped by the buffer member 7b due to the deformation in the shear direction of the buffer member 7b.

[0036] A rear-side second connecting piece 45 is connected to each of the rib portions 42 on the rear side in the depth direction. The rear-side second connecting piece 45 has an overall shape formed in an L-shape in a plan view and a rectangular flat plate shape in a side view. The rear-side second connecting piece 45 extends from the rib portion 42 inward in the width direction and then bends toward the rear side, and extends so as to protrude from the bent portion toward the rear side.

[0037] The pair of rear side second connecting pieces 45 are arranged at an interval in the width direction on the rear side of the main body 41. When the first fixing device 3 and the second fixing device 4 are arranged in the cage body 2, the pair of rear side second connecting pieces 45 of the second fixing device 4 are each arranged outward in the width direction from the pair of rear side first connecting pieces 35 of the first fixing device 3, as shown in Fig. 8(B) described later. Furthermore, each rear side second connecting piece 45 has a hole 45a that penetrates the rear side second connecting piece 45 in the width direction (X direction) at a position corresponding to the rear side first connecting piece 35.

[0038] Similar to the first fixing device 3, the second fixing device 4 is made of a material that has sufficient rigidity against vibration and is corrosion-resistant against liquids such as blood and disinfectants. As an example, the main body portion 41, the rib portion 42, and the rear side second connecting piece 45 of the second fixing device 4 may be integrally formed by bending a metal plate such as SUS.

[0039] Fig. 8(A) is a diagram showing a first connecting portion 5 on the front side of the first fixing device 3 and the second fixing device 4. Fig. 8(B) is a diagram showing a second connecting portion 6 on the rear side of the first fixing device 3 and the second fixing device 4. Fig. 9 is a diagram showing an example of the configuration of the first connecting portion 5 and the second connecting portion 6.

[0040] The first connecting portion 5 and the second connecting portion 6 are both constructed by connecting the first fastener 3 and the second fastener 4 using a set screw 51, which is an example of a bolt, and an elastically deformable bolt receiver 52.

[0041] As shown in FIG. 8(A), the first connecting part 5 is disposed at the center of the front of the cage body 2 and protrudes outward from the cage body 2 through an opening on the front side of the cage body 2. In the first connecting part 5, the front side first connecting piece 34 and the front side second connecting piece 44 are connected via a set screw 51 and a bolt receiver 52. The first connecting part 5 reduces the number of connecting points on the front side of the device, improving the workability during attachment and detachment. In addition, the space occupied by the first connecting part 5 on the front side of the blood collection device 1 is also reduced, which reduces the possibility that the first connecting part 5 will interfere with the blood collection work.

[0042] The second connecting parts 6 are disposed protruding from the rear opening 23 to the outside of the cage body 2, and as shown in Fig. 8(B), a pair are disposed on the rear side of the cage body 2 with a gap therebetween in the width direction. Set screws 51 are horizontally inserted inward from the outside in the width direction into each second connecting part 6, and the rear side first connecting piece 35 and the rear side second connecting piece 45 are connected via the set screws 51 and the bolt receivers 52. The second connecting parts 6 allow the set screws 51 to be easily inserted when performing attachment and detachment work on the rear side of the blood collection device 1, improving the operability during attachment and detachment.

[0043] As shown in Fig. 9, the bolt receiver 52 applied to the first connecting portion 5 and the second connecting portion 6 has a cylindrical body 52a formed of an elastic material such as rubber. A hole 52c through which the set screw 51 can be inserted is formed in the cylindrical body 52a in the axial direction. A nut 52d that screws with the set screw 51 is embedded in the cylindrical body 52a on one side (the lower side in Fig. 9) of the cylindrical body 52a. In addition, an annular flange 52b that protrudes radially outward from the outer periphery of the cylindrical body 52a is formed on the other side (the upper side in Fig. 9) of the cylindrical body 52a as an example of a buffer portion.

[0044] Here, in the first connecting portion 5, the cylindrical body 52a of the bolt receiver 52 is inserted into the hole 44a of the front side second connecting piece 44, and the front side first connecting piece 34 is disposed on the other side of the bolt receiver 52. As a result, the flange 52b is sandwiched between the front side first connecting piece 34 and the front side second connecting piece 44. In the above state, the set screw 51 is inserted from the hole 34a of the front side first connecting piece 34 into the hole 52c of the cylindrical body 52a (FIG. 9(B)). When the set screw 51 is screwed into the nut 52d, the front side first connecting piece 34 is sandwiched and held between the set screw 51 and the flange 52b. When the set screw 51 is screwed into the nut 52d, one side of the cylindrical main body 52a approaches the other side, and the front side second connecting piece 44 is sandwiched and held between the radially raised cylindrical main body 52a and the flange 52b (FIG. 9(C)).

[0045] 8(A), in the first connecting part 5, a set screw 51 is inserted downward from the upper side in the height direction, and a flange 52b made of an elastic material is interposed between the front side first connecting piece 34 and the front side second connecting piece 44 which are separated in the height direction (Y direction). Therefore, in the first connecting part 5, the vibration components in the height direction from the moving body are effectively damped by the compressive deformation of the flange 52b sandwiched between the front side first connecting piece 34 and the front side second connecting piece 44. Note that the vibration components in the depth direction and width direction can also be damped in the first connecting part 5 by the deformation in the shear direction of the flange 52 in the first connecting part 5.

[0046] Meanwhile, in the second connecting portion 6, the cylindrical body 52a of the bolt receiver 52 is inserted into the hole 35a of the rear side first connecting piece 35, and the rear side second connecting piece 45 is disposed on the other side of the bolt receiver 52. As a result, the flange 52b is sandwiched between the rear side first connecting piece 35 and the rear side second connecting piece 45. In the above state, the set screw 51 is inserted into the hole 52c of the cylindrical body 52a from the hole 45a of the rear side second connecting piece 45 (FIG. 9(B)). When the set screw 51 is screwed into the nut 52d, the rear side second connecting piece 45 is sandwiched and held between the set screw 51 and the flange 52b. When the set screw 51 is screwed into the nut 52d, one side of the cylindrical main body 52a approaches the other side, and the rear side first connecting piece 35 is sandwiched and held between the radially raised cylindrical main body 52a and the flange 52b (FIG. 9(C)).

[0047] 8(B), in the second connecting portion 6, a set screw 51 is inserted horizontally inward from the outside in the width direction of the car body 2, and a flange 52b made of an elastic material is interposed between the rear side second connecting piece 45 and the rear side first connecting piece 35 which are separated in the width direction (X direction). Therefore, in the second connecting portion 6, the vibration components in the width direction from the moving body are effectively damped by the compressive deformation of the flange 52 sandwiched between the rear side second connecting piece 45 and the rear side first connecting piece 35. Note that the vibration components in the depth direction and height direction can also be damped in the second connecting portion 6 by the deformation in the shear direction of the flange 52 in the second connecting portion 6.

[0048] 1, a sheet-like cushioning member 7a (for example, a shock absorbing material made of an elastic sheet such as anti-vibration rubber) may be sandwiched between the main body 31 of the first fixing device 3 and the main body 41 of the second fixing device 4. The cushioning member 7a can be disposed at any position offset from the first connecting portion 5 and the second connecting portion 6 within the range where the main body 31 and the main body 41 overlap.

[0049] As described above, by disposing the sheet-like buffer member 7a between the first fixing device 3 and the second fixing device 4, the vibration components in the height direction from the moving body are more effectively damped by the compressive deformation of the buffer member 7a. Note that the vibration components in the depth direction and width direction can also be damped by the buffer member 7a due to the deformation of the buffer member 7a in the shear direction.

[0050] The operation of this embodiment will be described below. The connection structure of the blood collection device 1 of this embodiment connects the blood collection device 1, which collects a donor's blood into a blood bag, to a cage body 2 that can house the blood collection device 1 inside and can receive vibrations from the outside. The cage body 2 has a bottom surface portion 21 facing the bottom surface of the blood collection device 1, and has openings on the front side and back side that communicate with the outside of the cage body 2. The connection structure includes a first fixture (first mount portion) 3 arranged on the bottom side of the blood collection device 1, and a second fixture (second mount portion) 4 arranged on the bottom side of the cage body 2 and connected to the first fixture 3. The first fastener 3 and the second fastener 4 are arranged on the front side of the car body 2, and each of them has a first connecting part 5 which connects the first fastener 3 and the second fastener 4 with a set screw (first bolt) 51 inserted in the height direction (first direction), and a second connecting part 6 which is arranged protruding outward from the rear surface of the car body 2 through an opening on the rear surface side of the car body 2, and connects the first fastener 3 and the second fastener 4 with a set screw (second bolt) 51 inserted along the width direction (second direction) intersecting with the first direction. The first direction and the second direction are each selected from a direction parallel to a horizontal plane or a direction inclined downward with respect to the horizontal plane. The set screw of the first connecting part 5 and the set screw of the second connecting part 6 are arranged between the first fastener 3 and the second fastener 4, and are each screwed into a bolt receiver 52 having an elastically deformable buffer part. According to this embodiment, when the blood collection device 1 and the cage 2 are connected, the first connecting part 5 has a damping effect on vibrations in a first direction due to the buffer part of the bolt receiver 52, and the second connecting part 6 has a damping effect on vibrations in a second direction due to the buffer part of the bolt receiver 52. Therefore, in this embodiment, since vibrations in different directions can be damped by the first connecting part 5 and the second connecting part 6, vibrations from the cage 2 to the blood collection device 1 can be efficiently suppressed, and malfunctions such as breakdowns due to vibrations from a moving body can be suppressed. Furthermore, according to this embodiment, the first connecting part 5 and the second connecting part 6 having a vibration damping function can be housed compactly between the blood sampling device 1 and the cage 2, so that the limited space within the movable body can be effectively utilized. Furthermore, compared to a connection structure in which the blood collection device 1 is fixed by inserting a bolt from the underside of the basket body 2, the connection structure of the blood collection device 1 in this embodiment significantly improves the workability when fixing the blood collection device 1 to the basket body 2, and also makes it possible to prevent problems such as loss of the bolt.

[0051] The present invention is not limited to the above-described embodiment, and various improvements and design changes may be made without departing from the spirit of the present invention.

[0052] In the above embodiment, a configuration example has been described in which the first fixing device 3 is prepared separately from the blood collection device 1, and the first fixing device 3 is detachably attached to the bottom surface of the blood collection device 1. However, the configuration of the present invention is not limited to the above, and the first fixing device 3 (first mounting portion) may be integrally formed on the bottom surface of the blood collection device 1. In the above embodiment, a configuration example has been described in which the second fixing device 4 is prepared separately from the car body 2, and the second fixing device 4 is detachably attached to the car body 2. However, the configuration of the present invention is not limited to the above, and the second fixing device 4 (second mounting portion) may be formed integrally with the car body 2.

[0053] Furthermore, the insertion direction of the set screw 51 in the first connecting part 5 and the second connecting part 6 in the present invention is not limited to the combination of the above embodiments, and can be changed as appropriate. For example, the first direction which is the insertion direction of the set screw 51 in the first connecting part 5 and the second direction which is the insertion direction of the set screw 51 in the second connecting part 6 can be changed by selecting from directions other than upward (directions parallel to the horizontal plane or directions inclined downward with respect to the horizontal plane). By inserting the setscrew 51 in a direction parallel to the horizontal plane or in a direction inclined downward with respect to the horizontal plane, it is possible to prevent the setscrew 51 from falling off and being lost when it becomes loose.

[0054] In the above embodiment, a configuration example has been described in which the rib portion 42 is formed on the second fastener 4, and the sheet-like cushioning member 7b is sandwiched between the rib portion 42 and the cage body 2.
