Abstract

PROBLEM TO BE SOLVED: To provide a connection jig capable of demonstrating excellent collision safety while maintaining a constant distance between a patient and a drip stand so that the patient can be put on a drip safely.SOLUTION: A first attachment member 2 of a connection jig 1 is removably attached to an auxiliary member 72 that is attached to a frame 77, etc. of a bed, stretcher, and a wheelchair. The second attachment member 4 is movable along the support post of a drip stand. Thus, when the first attachment member 2 is lifted/lowered in a case where a height adjustment mechanism of a bed or a stretcher is operated, only the second attachment member 4 is lifted/lowered via a connection member 3, so that the fall of the drip stand can be prevented. An opening/closing member of the second attachment member 4 is abutted to the support post of the drip stand and the second attachment member 4 is gradually pressurized against the support post from the abutment state, so that the support post can be fitted into the second attachment member 4. Thus, the attachment is facilitated.SELECTED DRAWING: Figure 7

Description

  The present invention relates to a connecting jig that connects an infusion stand and a medical bed, a stretcher, or a wheelchair, and keeps the distance between them constant.

  When a patient who is receiving an infusion is sleeping on a medical bed, stretcher, etc. or sitting on a wheelchair, the length of the infusion tube connecting the infusion device and the patient is finite. The holding drip stand is installed near a medical bed, stretcher, wheelchair or the like used by the patient. However, since this infusion stand needs to be moved with the patient when the instilling patient moves, the infusion stand is equipped with a caster for movement, and the infusion stand to be moved with the patient is the caster of this caster. Due to the presence, the distance between the patient and the drip stand is not constant, and the drip may be removed from the patient when the distance is too far. In addition, when administering an infusion while the patient is sleeping on the bed, it is necessary to keep the infusion stand still without moving it, but the caster moves with a slight vibration, and the infusion stand moves to the bed and its By leaving the patient sleeping on top, the patient may not be able to receive the infusion safely. In addition, when a patient who needs infusion moves in a hospital with a wheelchair, the patient himself / herself needs to move with an infusion stand, which is a burden on the patient. In order to keep the distance between the patient and the drip stand constant, the following proposals have been made.

  Patent Document 1 discloses a connecting device that connects a traction device (such as a stretcher) and a device to be pulled (such as a drip stand) that is pulled by the traction device. Rigid rods are connected to the towing device and the towed device by bolts or the like, and the rigid rods are connected by elastically deforming members. This Patent Document 1 moves a towed device connected to the towed device at the same time by moving the towed device. During this movement, even if the towed device is displaced from the course direction, The elastic deformation member used as the connecting member causes the towed device to swing largely so that the towed device does not skid due to its elastic force, and returns the towed device to an appropriate path position. It is intended to be transported safely at the same time.

  Patent Document 2 discloses a traction device in which a wheeled stand such as a drip stand is connected to a towed vehicle such as a wheelchair and the wheeled stand is pulled by the towed vehicle. The connecting member used in the traction device is a rigid body and is fixed by a bolt or the like, and can be rotated with one degree of freedom around the axle of the traction vehicle. In this prior art, when the tow vehicle pulls the wheeled stand, even if there is a step in the moving path, the wheeled stand is rotated around the axle of the towed vehicle by the connecting member without being caught by the step. In this way, this prior art is intended to ensure stable movement of the towed wheeled stand.

  However, since Patent Documents 1 and 2 connect a drip stand and a wheelchair or a stretcher by a rigid body, when the connection member collides with an object during the movement of these devices, the connection member The object may be damaged due to rigidity.

  As a conventional technique in which the connecting portion is not a rigid rod but a flexible rod, Patent Document 3 connects a plurality of piece members that rotate only in the horizontal direction with respect to the floor, and these are integrated in the horizontal direction. A flexible support device configured to bend only is disclosed. An electric lamp, an infusion tube, or the like is connected to one end of the support device, and an edge of a desk or a handrail of a bed is connected to the other end. The support device of Patent Document 3 bends only in a direction horizontal to the floor, so that even if an electric light or the like connected to one end of the support device is heavy, the weight is bent in a direction perpendicular to the floor due to its own weight. There is no attempt to keep the electric lamp or the like at an appropriate height.

  However, in Patent Documents 1 and 2, since the connecting member is a rigid body, as described above, the object damage at the time of collision is relatively large, and the interval between devices connected by the connecting member cannot be changed. Even if the frontage tries to pass through a narrow passage, there is a possibility that it cannot pass. Furthermore, since Patent Documents 1 and 2 are firmly fixed by a rigid body, in a medical bed or a stretcher or the like, when the height is adjusted, the connection member fixed to them and the connection member are connected to the connection member. The drip stand also moves as the height is adjusted, and the drip stand may fall over. Furthermore, in Patent Documents 1 and 2, since the fixing method of the connecting member is a bolt or the like, a bed, a stretcher, a wheelchair or the like dedicated to the connecting member is required, and the versatility is low.

  Moreover, since the support apparatus of patent document 3 does not bend in the direction perpendicular | vertical with respect to a floor, when the height adjustment operation | movement of a medical bed or a stretcher etc. is performed like patent documents 1 and 2, a support apparatus and support The drip stand connected to the apparatus may also fall because the height changes at the same time. Moreover, since this patent document 3 supports a drip tube directly with a support device, a stretcher or a wheelchair or the like used by a patient is connected to a drip stand using the support device, and these are simultaneously connected. When trying to move, there exists a possibility that the tube for infusion may be damaged.

  The present invention has been made in view of such a problem, and a coupling jig having excellent collision safety while keeping the distance between the patient and the drip stand constant so that the patient can receive drip safely. The purpose is to provide.

  In this case, the wheelchair is provided with wheels provided on both sides, a seat where a person sits between the wheels, and a second wheel which is disposed in front of the wheel and moves the wheelchair together with the wheel. And a footrest on which a person puts his / her foot, and a frame serving as a framework for supporting these wheels, the second wheel, and the seat, and the auxiliary member can be configured to be attached to the frame.

  In the connecting jig according to the present invention, for example, the opening / closing member has a U-shape, and the curved portion constitutes the distal end of the opening / closing member that is locked to the main body at the other end side of the opening, The both ends are bent vertically so as to face each other, the bent both ends are rotatably supported on the inner surface of the main body, and the positions of the both ends supported on the inner surface of the main body are the openings. It may be configured to be provided at different positions in the direction from the one end side to the other end side of the part, and for example, the connecting member may be configured to have flexibility. Further, for example, the connecting member is connected to the first mounting member and is a rigid first member, and is connected to the second mounting member and is a rigid second member, the first member and the first member. The two members may be configured to have a joint portion that is relatively rotatably connected.

Further, for example, the first mounting member is screwed into the bolt having a head and a screw portion, a cylindrical elastic bulging member fitted to the screw portion, and the head. And a nut that increases or decreases the outer diameter of the bulging member by pushing the bulging member in a longitudinal direction between the bulging member and the bulging member in a pipe provided in a bed, stretcher or wheelchair. The bulging member may be bulged by inserting and adjusting the distance between the head and the nut, and the bulging member may be frictionally engaged with the pipe. The first mounting member is

  Hereinafter, embodiments of the present invention will be specifically described with reference to the accompanying drawings. 1A and 1B are perspective views showing a connecting jig used in the embodiment of the present invention, and FIG. 1C is an upper surface showing an upper surface of a second mounting member of the connecting jig. FIG. 1 and FIG. 1D are cross-sectional views showing a cross section of the first mounting member of the connecting jig. As shown to Fig.1 (a) and (d), the connection jig | tool 1 is provided with the 1st attachment member 2 detachably attached to the bed, stretcher, or wheelchair which a patient utilizes. The first mounting member 2 is provided with, for example, a bolt 28 including a head portion 24 and a screw portion 22, and the screw portion 22 has, for example, a dimension of M8 and is below the bolt neck. The length is 80 mm. For example, a first cylindrical member 29 is provided on the head 24 side, and a screw portion 22 is inserted through the first cylindrical member 29. Further, a second cylindrical member 25c having the same outer diameter as that of the first cylindrical member 29 is provided so as to be adjacent to the first cylindrical member 29, and the screw portion 22 is inserted into the second cylindrical member 25c. The first cylindrical member 29 and the second cylindrical member 25c have end surfaces that are in contact with each other in the longitudinal direction and are inclined in the same direction, which are an inclined surface 29a and an inclined surface 25d, respectively. A nut 21 is screwed into the screw portion 22, and the nut 21 fastens the first cylindrical member 29 and the second cylindrical member 25 c between the head portion 24 and the nut 21. And this 1st cylindrical member 29 and the 2nd cylindrical member 25c are inserted in the pipe provided in the bed, the stretcher, or the wheelchair, By adjusting the space | interval between the head 24 and the nut 21, 1st The shaft of the first cylindrical member 29 and the shaft of the second cylindrical member 25c are eccentric to each other, and the outer surface thereof is frictionally engaged with the pipe. The screw portion 22 is inserted into a through hole (not shown) provided in the horizontal portion 25a of the L-shaped metal fitting 25 having an L-shaped cross section, and the second cylindrical member 25c is surrounded by the through hole. , And welded to the L-shaped bracket 25. For example, the L-shaped metal fitting 25 has a thickness of 3.2 mm.

  Further, as shown in FIGS. 1A, 1B, and 1C, the connecting jig 1 is engaged with a support column 52 of the drip stand and is movable along the support column 52. A member 4 is provided. The second mounting member 4 has a frame-shaped main body 41 that engages with the post 52 of the infusion stand, and the main body 41 has an opening 43 that allows the support 52 to enter and exit from the main body 41. Is provided. Further, the opening / closing member 44 rotatably provided on the main body 41 on one end side of the opening 43 has its tip engaged with the inner surface of the main body 41 on the other end of the opening 43. Yes. For example, the opening / closing member 44 has a U-shape, and the curved portion forms the tip of the opening / closing member 44 that is locked to the main body 41 on the other end side of the opening 43. Further, both end portions of the opening / closing member 44 are bent vertically so as to face each other, and both bent end portions are rotatably supported on the inner surface of the main body portion 41. The main body 41 includes, for example, two first protrusions 47 on the inner surface so that the distance from the opening 43 is different in the direction from the one end side to the other end side of the opening 43. A second protrusion 48 is provided. The first protrusion 47 is located closer to the opening 43 than the second protrusion 48. The first protrusion 47 and the side face of the second protrusion 48 are parallel to the inner surface of the main body 41. 48a is drilled. By inserting bent end portions of the opening / closing member 44 into the holes 47a, 48a, the main body 41 supports the opening / closing member 44 so as to be rotatable about the holes 47a, 48a. That is, the bent both ends of the opening / closing member 44 are provided at different positions on the inner surface of the main body 41 in the direction from the one end side to the other end side of the opening 43. Thereby, when the opening / closing member 44 rotates about the bent both ends, the tip of the opening / closing member 44 is urged in a direction to contact the other end of the opening 43 of the main body 41. Elastic force is applied. The opening / closing member 44 is, for example, spring steel. The main body 41 is provided with a projecting portion 46 on the opposite side of the opening 43 in a top view. The second mounting member 4 is made of PP resin, for example, and is formed by injection molding.

  In the connecting jig 1, the first mounting member 2 and the second mounting member 4 are connected by the connecting member 3. In the vertical portion 25b of the L-shaped metal fitting 25 of the first mounting member 2, for example, a tapped through hole (not shown) is formed, and one end portion of the connecting member 3 is brought into contact with the through hole. The connecting member 3 is fixed to the L-shaped bracket 25 by a first bolt 26 having a spring washer (not shown) and a nut (not shown) provided at one end of the connecting member 3. For example, the connecting member 3 has a diameter of 14 mm and a length of 300 mm. Moreover, the dimension of the nut provided in the one end part of the connection member 3 is M6, for example. Further, the first bolt 26 is, for example, the type B20, and the size is M6 like the nut. Further, a through hole (not shown) is provided in the main body portion 41 of the second mounting member 4, and the second bolt 42 and the other end portion of the connecting member 3 are provided through the through hole. The connecting member 3 is fixed to the main body 41 by a nut (not shown). The dimension of the nut provided at the other end of the connecting member 3 is, for example, M6.

  Next, the infusion stand will be described. As shown in FIG. 4, the drip stand 51 has, for example, five leg portions 54a, 54b, 54c, 54d, and 55e extending from the central portion, and the five leg portions 54a, 54b, 54c, 54d, and 55e. Casters 55a, 55b, 55c, 55d, and 55e are provided at the tip. A support column 52 that supports the infusion bag 53 is erected at the central portion that is the base end of the leg portions 54a, 54b, 54c, 54d, and 55e. A suspension fitting 56 extending in the horizontal direction is provided at the upper end of the support column 52, and an infusion bag 53 is suspended at one end of the suspension fitting 56. A tip of an infusion tube 57 connected to the infusion bag 53 is suspended from the other end of 56.

  Next, the bed will be described. A bed 61 shown in FIG. 4 is a bed according to a reference example of the present invention. As shown in FIG. 4, for example, the bed 61 is provided with a bed part 64 for a patient to sleep, and a side part of the bed 61 is used to prevent a patient sleeping on the bed part 64 from falling. A fence 63 is provided. A pipe 62 is provided on the frame of the bed 61. Unlike the drip stand 51 of the present embodiment, the pipe 62 is for installing an infusion bar only having a hanging metal fitting 56 on the upper end of the bar on the side of the bed 61. By inserting the tip of the drip bar into the pipe 62, the drip bar is installed on the side of the bed. In the present embodiment, the drip bar is not used, and this pipe 62 is used to attach the first attachment member 2 of the connecting jig 1 to the bed 61.

  Next, the operation when the connecting jig 1 of the embodiment of the present invention is used for the bed 1 of the reference example will be described. FIG. 1D is a cross-sectional view showing a cross section of the first mounting member 2, and FIG. 2 shows the trajectories of the tips of the first vertical portion 44 a and the second vertical portion 44 b of the opening / closing member 44 of the second mounting member 4. It is a top view. First, a method of attaching the first attachment member 2 to the bed 61, the wheelchair 71, or the stretcher 81 will be described. The nut 21 is tightened with the first cylindrical member 29 and the second cylindrical member 25c of the first mounting member 2 inserted into the pipes 62, 72, 82 provided on the bed 61, the wheelchair 71 or the stretcher 81. By adjusting the distance between the head 24 and the nut 21, the distance between the head 24 and the nut 21 tends to be reduced. At that time, the first cylindrical member 29 tries to move to the nut 21 side, but cannot move to the nut 21 side because the second cylindrical member 25c is on the nut 21 side. At this time, the first cylindrical member 29 moves in the inclined direction along the inclined surface 25d of the second cylindrical member 25c facing the inclined surface 29a, whereby the axis of the first cylindrical member 29 and the second The shaft of the cylindrical member 25c is eccentric to each other, and the distance between the head 24 and the nut 21 is reduced. Thus, since the 1st cylindrical member 29 moves to the inclination direction of the inclined surface 29a, the 1st cylindrical member 29 also changes the position of the direction perpendicular | vertical to the screw part 22. As shown in FIG. Thereby, the width in the direction perpendicular to the screw portion 22 is the outer diameter of the second cylindrical member 25c at the time of pipe insertion, but after tightening the nut 21, the outer diameter of the second cylindrical member 25c is Since the distance that the first cylindrical member 29 is displaced in the direction perpendicular to the screw portion 22 is added, the width of the first cylindrical member 29 increases. By tightening the nut 21 until this width becomes the width of the internal space of the pipe, the first mounting member 2 is frictionally engaged with the pipe. Thereby, the connection jig | tool 1 is attached to a bed, a stretcher, or a wheelchair.

  Next, a method for attaching the second attachment member 4 to the drip stand column 52 will be described. As shown in FIG. 2, the opening / closing member 44 of the second mounting member 4 of the connecting jig 1 has a U shape and is disposed so as to close the opening 43 (shown by a two-dot chain line in the figure). position). The two vertical portions of the opening / closing member 44 are a first vertical portion 44a and a second vertical portion 44b, respectively. The first vertical portion 44a is shorter in length than the second vertical portion 44b. In the first vertical portion 44 a and the second vertical portion 44 b, bent portions of the end portions are inserted into the holes 47 a and 48 a of the first protrusion 47 and the second protrusion 48 of the main body 41. When the first vertical portion 44a is rotated inside the main body 41 with the hole 47a as an axis, the locus 49a at the tip thereof rotates the second vertical portion 44b inside the main body 41 with the hole 48a as an axis. It is on the hole 47a (axis) side from the locus 49b of the tip. However, when the opening / closing member 44 is actually rotated inside the main body 41 around the holes 47a and 48a, the first vertical portion 44a and the second vertical portion 44b, which originally have different trajectories at their tips, have the same trajectory. Therefore, the first vertical portion 44a is pulled to the opposite side of the hole 47a (axis) side from the locus 49a, and the second vertical portion 44b is compressed to the hole 48a (axis) side from the locus 49b. . Thereby, a compression force acts on the first vertical portion 44a so as to resist the tensile force, and a tension force acts on the second vertical portion 44b so as to resist the compression force, thereby opening and closing member 44. In this case, a force for returning to the original position, that is, a force for urging the opening 43 is applied.

  When the opening / closing member 44 is pressed against the drip stand column 52, a force in the direction opposite to the biasing direction is applied to the opening / closing member 44, and the opening / closing member 44 is attached to the body portion 41 of the second mounting member 4. While rotating inward, the drip stand support 52 is sandwiched between the opening / closing member 44 and the main body 41. When the drip stand support 52 is separated from the opening / closing member 44 and completely within the main body 41 of the second mounting member 4, the opening / closing member 44 does not receive a force in a direction opposite to the biasing direction. Return to the original position. Thereby, the 2nd attachment member 4 engages with the support | pillar 52 of an infusion stand. As shown in FIG. 1C, when the support column 52 enters the space 41 a on the one end side of the opening 43 inside the main body 41, the support column 52 is moved even if the opening / closing member 44 is rotated. Since it cannot be removed, the projecting portion 46 prevents the support column 52 from entering the space 41 a on the one end side of the opening 43.

  Next, a method for attaching the connecting jig 1 to the bed will be described. FIG. 4 is a perspective view showing a state where the connecting jig 1 is connected to the bed and the drip stand, and FIG. 5 is an enlarged view of the connecting jig in a state where the connecting jig 1 is connected to the bed and the drip stand. FIG. 6 is a perspective view showing a state where the connecting jig 1 is removed from the drip stand. As shown in FIGS. 4 to 6, in the present embodiment, the first attachment member 2 of the connecting jig 1 is attached to the bed 61 using a pipe 62 provided on the frame of the bed 61. As described above, the first cylindrical member 29 and the second cylindrical member 25c of the first mounting member 2 are inserted into the pipe 62, and the nut 21 is tightened, whereby the first mounting member 2 is frictionally engaged with the pipe 62. . On the other hand, as described above, the second mounting member 4 causes the opening / closing member 44 of the second mounting member 4 to abut on the support column 52 of the drip stand 51, and from this state, the second mounting member 4 is pushed to the support column 52. The support 52 is engaged with the support 52 by fitting the support 52 into the second mounting member 4. Therefore, the bed 61 and the drip stand 51 are connected by the connecting jig 1.

  As described above, since the support 52 can be fitted into the second mounting member 4 simply by pressing the second mounting member 4 against the support 52, the mounting is easy. Further, since the support column 52 and the bed 61 of the drip stand 51 are connected by the connecting member 1, the distance between the drip stand 51 and the bed 61 can be kept constant and the drip stand 51 can be kept stationary. . Moreover, since the 2nd attachment member 4 of the connection jig | tool 1 is movable along the support | pillar 52, when changing the height of the bed 61, the 1st attachment member 2 fixed to the bed 61 moves up and down. As a result, even if the second mounting member 4 moves up and down, only the second mounting member 4 moves along the column 52 to prevent the column 52 from moving and falling over. be able to.

  In addition, when the patient sleeping on the bed removes the second attachment member 4 that engages with the support column 52 of the infusion stand 51 without requiring infusion, the second attachment member 4 and the support column 52 engage with the support column 52. Since the engagement of the column 52 can be released simply by opening the opening / closing member 44 of the second mounting member 4 and detaching the second mounting member 4 from the column 52 from this state, the removal is easy. Then, as shown in FIG. 6, when removing the connecting jig 1 engaged with the support column 52, for example, if the connecting member 3 has flexibility, it can be easily bent. After the connecting member 3 of the removed connecting jig 1 is bent horizontally, it is bent vertically and upward to raise the second mounting member 4. Thereby, the connection jig | tool 1 attached to the bed by the 1st attachment member 2 can be easily arrange | positioned in the position which does not become obstructive. Thus, the connecting jig 1 can be stored compactly when not in use by the connecting member 3 having flexibility. Further, when the second mounting member 4 is again engaged with the column 52 from this state, the second mounting member 4 approaches the column 52 by bending the connecting member 3 vertically and downward and then horizontally. From this state, the second mounting member 4 is engaged with the column 52 by pressing the opening / closing member 44 of the second mounting member 4 against the column 52.

  The first embodiment of the present invention will be described below. In the present embodiment, the connecting jig 1 is used for connecting a wheelchair and an infusion stand. FIG. 7 is a perspective view showing a state in which the connecting jig 1 is connected to the wheelchair 71 and the drip stand 51, and FIGS. 8 and 9 similarly show the connecting jig 1 connected to the wheelchair 71 and the infusion stand 51. It is the expanded perspective view. As shown in FIGS. 7 to 9, the wheelchair 71 is disposed between the wheels 73 provided on both sides, the seat 74 where a person sits between the wheels 73 on both sides, and the front of the wheels 73. A second wheel 75 for moving the wheelchair 71 together with the wheel 73 and a footrest 76 on which a person places his / her foot are provided.
