Description

  TECHNICAL FIELD The present invention relates to a method for increasing the protruding length of a patient platform in a wheelchair with a transfer function having a function of transferring a patient between a bed and a wheelchair, and a wheelchair with a transfer function provided with this method. It is.

With the arrival of an era called an aging society, the number of elderly and sick who need care is increasing rapidly.
The task of transferring a patient from a wheelchair to a bed or from a bed to a wheelchair requires a lot of time and physical strength, and is currently a burden on the caregiver.

Various proposals have been made to reduce such a burden.
In order to reduce the burden on the caregiver, the applicant has also proposed a wheelchair with a transfer function in which the lower frame shrinks in the width direction and an assistant is attached to the side so that the patient can easily move on the bed. (Patent Document 1).

  As shown in FIG. 10, such a wheelchair 30 with a transfer function can be normally used as a care wheelchair 30 ′. When the patient 32 is transferred from the bed 34 to the wheelchair side, the seat 9 The patient platform 8 including the folded back 33, the temporary leg platform 11 and the like is brought close to the side of the bed 34, and the patient platform 8 is pushed by pushing the seat 9 with the back 33 of the patient platform 8 standing. After being projected on the bed 34, it is configured to be elongated in a substantially horizontal direction.

Such a wheelchair 30 (30 ') with a transfer function provided by the applicant of the present application can be transferred to the patient platform 8 without any effort while the patient 32 is laid on the bed 34. This is a wheelchair.
JP 2002-224166 A

By the way, even the wheelchair 30 (30 ′) with a transfer function disclosed in Patent Document 1 has found the following improvements.
That is,
(A) The protruding length of the patient platform 8 relative to the bed 34 is not yet sufficient, and the patient platform 8 may not reach the point where it contacts the patient 32. In such a case, moving the patient 32 to the place where the patient 32 comes into contact with the patient platform 8 on the bed 34 is a great labor burden for the assistant.

  (B) It is possible to separate the patient platform 8 from the lower frame 10 that supports the patient platform 8 so that the patient platform 8 contacts the patient 32. However, the patient platform 8 can be removed from the lower frame 10. If it protrudes, the frictional resistance between the patient platform 8 and the bed 34 will increase, and a large amount of labor will be required for the push-back operation of the patient platform 8 with respect to the bed 34.

In view of such a situation, the present invention can make the protruding length of the patient platform that can put the patient lie sideways longer with respect to the bed, thereby easily placing the patient. It is an object of the present invention to provide a method for increasing the protruding length of a patient platform in a wheelchair with a transfer function that can be changed, and a wheelchair with a transfer function provided with this method.

In order to achieve the above object, the method of increasing the protruding length of the patient platform in the wheelchair with a transfer function according to the present invention,
The seat portion of the patient platform is composed of two layers of an upper platform and a lower platform, the upper platform is configured to be movable with respect to the lower platform, and the lower platform is a pair of left and right Configured to be movable with respect to the lower frame for holding the load accommodated between the wheels of the
Furthermore, the lower frame is arranged so as to be movable in both directions on either the left or right wheel side or on the other wheel side along a horizontal axis connecting the wheels.
When the patient is transferred from the bed to the wheelchair or from the wheelchair to the bed, the side surface of the wheelchair body is brought closer to the side of the bed, and the lower frame is moved along the axis toward the wheel on the bed side. In conjunction with the movement, the two-layer seat part is moved from the lower frame together with the upper and lower bases onto the bed,
Subsequent to this movement, the length of the patient platform is extended by moving the upper platform from the lower platform onto the bed.

  According to such a method of extending the protruding length, the lower frame is slid onto the bed in two layers in conjunction with moving the lower frame closer to the bed side along the horizontal axis, Thereafter, the base above the two-seat stool is moved onto the bed relative to the base below, so that the protruding length of the bed as a whole can be increased.

  In addition, since the lower frame is movable with respect to the horizontal axis, when the lower frame is brought closer to the bed side, the two-layered seating portion can be moved closer together in conjunction with the bed side. it can. Further, when the lower frame is brought closer to the bed side, the assistant can approach the bed and assist. Therefore, the replacement work is facilitated.

Furthermore, the wheelchair with a transfer function according to the present invention is:
A patient platform with a two-layered seat on the upper and lower platforms;
A horizontal axis connecting the pair of left and right wheels;
The movement is guided along the horizontal axis, and is arranged in a state where it is expanded between the pair of left and right wheels, or in a state where the width is reduced to the left or right wheel side. A lower frame, and
The upper platform is movable relative to the lower platform, and the lower platform is movable relative to the lower frame;
When the patient is transferred from the bed to the wheelchair or from the wheelchair to the bed, the width of the lower frame is approached to the bed along the axis from a state in which either side of the wheelchair body is close to the side of the bed. The seat portion of the two-layer structure is formed in two layers while forming a space for the assistant to approach the bed between one wheel located far from the bed and the lower frame by contracting in the direction. Slide all over the bed,
Furthermore, from this state, the upper table is slid from the lower table onto the bed, and the protruding length of the patient table is increased.

According to the wheelchair with a transfer function having such a configuration, the seat of the two-layered patient platform can be moved a long distance so as to come into contact with the patient. Can be replaced. Furthermore, since the lower frame is shrunk in the direction approaching the bed with respect to the horizontal axis, an assistant can approach the bed,
Helper's labor can be reduced as much as possible.

In addition, with such a configuration, the patient can be repositioned even when the wheelchair body is brought closer to the bed from either the left or right side.
Furthermore, the wheelchair with a transfer function according to the present invention is:
A patient platform with a two-layered stool configured such that the upper platform is movable relative to the lower platform;
When the patient platform protrudes onto the bed, a support solid support column frame that supports the patient platform from below, where a space for the assistant to enter the column frame and walk up to the bed side is created,
Formed on the upper part of one side of the three-dimensional support frame, and when the patient is remounted, if the patient is tilted from the vertical direction to the horizontal direction on the bed, it becomes a cradle for placing the patient platform protruding on the bed. A bed bridge made of a flat plate on which a plurality of wheels are braked and also serves as a patient armrest is provided.

  Even with such a structure, the seat of the two-layered patient platform can be moved so as to come into contact with the patient, so that the patient can be remounted with minimal effort by the assistant, Since the assistant can approach the bed side by entering the support frame of the lower frame, the patient can be replaced with less labor of the assistant.

  According to the method of increasing the protruding length of the patient platform in the wheelchair with a transfer function according to the present invention, the lower frame is moved to the bed side together with the lower table, and the upper table is further moved from the lower table to the bed side. Since it is configured to move, the protruding length of the bed as a whole can be increased. Also, by moving the lower frame closer to the bed, a space is formed between the side of the lower frame that is farther from the bed and the wheel that is farther from the bed. A space to approach the side is born, and the labor of assistance can be reduced as much as possible.

  In addition, according to the wheelchair with a transfer function according to the present invention, the lower frame is moved in the direction approaching the bed with respect to the horizontal axis together with the stool of the patient platform having two upper and lower layers, and the upper platform Is moved in the direction approaching the bed from the lower frame, so that the protruding length of the patient platform with respect to the bed can be increased.

  Furthermore, in the wheelchair with a transfer function according to the present invention, by moving the lower frame in the direction approaching the bed along the horizontal axis, the wheel positioned far from the bed and the wheel far from the bed of the lower frame are moved. A space for the assistant to approach the bed is formed between the side surface and the assistant can enter the space, so that the assistance effort can be reduced as much as possible.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 shows a case where a patient is transferred from a bed to a wheelchair using a wheelchair with a transfer function according to an embodiment of the present invention. FIG. 2 is an exploded perspective view showing a part of FIG. FIG. 3 is a view when FIG. 2 is assembled. FIG. 4 is an exploded perspective view when a part of FIG. 3 is assembled. In FIG. 1, the same elements as those in FIG. 10 will be described with the same reference numerals. In the following description, for the sake of convenience, in the wheelchair or the like, the “width direction” is the XX ′ direction in FIG.

This wheelchair 20 with a transfer function enables the patient 32 lying on the bed 34 to be transferred from the bed 34 to the patient platform 8 or from the patient platform 8 to the bed 34. 8, a lower frame 10 that can support the load of the patient platform 8 and move in the width direction (XX ′ direction), and a pair of wheels 12 and 12 ′ on both sides of the lower frame 10. Further, a pair of auxiliary wheels 18 and 18 'are provided on the front side of the wheels 12 and 12'.

  The wheels 12 and 12 ′ are connected by a shaft 16 that is horizontal and extends in the width direction. Accordingly, the distance between the wheels 12 and 12 ′ is always constant, and the lower frame 10 is guided in a substantially horizontal direction along the shaft 16.

In a normal use state, the lower frame 10 is disposed in a state where it extends between the pair of wheels 12, 12 'as shown in FIG.
The lower frame 10 is arranged so as to be movable in either the X direction or the X ′ direction between the wheels 12 and 12 ′ via a pair of left and right bearing boxes 24 and 24 with respect to the horizontal axis 16. ing.

  That is, in FIG. 1, when the lower frame 10 is pushed in the X direction, the lower frame 10 moves in the direction of approaching the bed 34 together with the lower base 6. It is also possible to move in the reverse direction, that is, in the X ′ direction away from the bed 34.

  The lower table 6 is supported on the lower frame 10 so as to be movable in both directions X-X ′. That is, as shown in FIG. 5, the lower frame 10 is arranged in a state where it extends between the pair of wheels 12, 12 ′, or as shown in the state of FIG. It is possible to arrange it in a state of narrowing the width on the wheel 12 ') side. Thus, the lower frame 10 is configured such that its own length in the width direction can be freely expanded and contracted.

  As shown in FIG. 3, the stool portion 9 of the patient platform 8 includes an upper base 5 formed in a substantially rectangular shape and a lower base 6 formed in a substantially same shape as the upper base 5. The upper base 5 is configured to be movable in the XX ′ direction with respect to the lower base 6. Further, when used as a wheelchair, the upper surface of the upper table 5 on which the patient 32 sits down and becomes a seating surface is provided with appropriate cushioning properties.

  The seat portion 9 having such a configuration is normally arranged in two upper and lower stages as shown in FIGS. 3 and 5. When the patient 32 is replaced or the like, as shown in FIG. 6, first, the lower frame 10 is pushed toward the bed 34, so that the patient platform 8 is brought together with the lower frame 10 and the lower frame 10. It moves in the width direction (direction approaching the bed 34). As a result, the upper table 5 and the lower table 6 on the seat 9 of the two-layer structure patient table 8 are integrally projected onto the bed 34. Next, from the state of FIG. 6, the upper base 5 is moved in the width direction with respect to the lower base 6 and arranged in the state of FIG. 7. For example, as shown in FIG. 3, the structure in which the upper base 5 is moved relative to the lower base 6 from the state where the seat 9 of the patient platform 8 is arranged in two upper and lower stages is any structure. In this embodiment, as shown in FIGS. 1, 2 and 4, a structure is adopted in which the frictional resistance is reduced by using a large number of rollers 14.

  That is, in this embodiment, three rectangular grooves in the width direction are formed on the upper surface of the lower base 6, and a large number of rollers 14 are accommodated in these grooves. Three roller fitting tracks 1 into which the rollers 14 are fitted in this way are formed side by side on the upper surface of the lower base 6, and in each track 1, two metal fittings 2 with holes can move. Contained.

Such a roller fitting track 1 is formed not only on the upper surface of the lower table 6 but also on the lower surface of the lower table 6 and the lower surface of the upper table 5. And the metal fitting 2 with a hole arrange | positioned at the upper surface of the lower base 6 is matched with the attachment metal fitting 2 arrange | positioned at the lower surface of the upper base 5, and the base end 3a side of the bar shaft handle 3 is inserted in each hole. As a result, the upper table 5 is supported so as to be movable with respect to the lower table 6. By adopting such an attachment structure of the upper table 5 to the lower table 6, the upper table 5 can move in the width direction with respect to the lower table 6.

  On the other hand, the metal fittings 2 with holes arranged on the lower surface of the lower base 6 are matched with the metal fittings 2 with holes in the horizontal side plate portions 7 and 7 at the upper part of both side surfaces of the lower frame 10, as shown in FIG. The lower base 6 is attached to the lower frame 10 side by inserting the shaft rod 4 therethrough.

  The lower frame 10 is composed of a pair of left and right side frames and an X-type frame interposed between the side frames. The X-type frames are arranged one by one on the front and rear of the wheelchair body. When the wheelchair 20 with a transfer function is used as a normal wheelchair, as shown in FIG. 5, the X-type frame portion is arranged in an open state between the wheels 12 and 12 ′. On the other hand, when changing from a bed to a wheelchair, etc., as shown in FIG. 6 or FIG. 7, the X-shaped frame portion is folded into a state of being contracted in the width direction (in this case, the X direction).

  In this embodiment, as disclosed in JP-A-2002-224166, when the X-type frame of the lower frame 10 is folded as shown in FIGS. 6 and 7, the X-type frame is deformed. A structure has been adopted in which the associated travel allowance is all downward.

  That is, as can be seen by comparing the X-type frames of FIGS. 5 and 6, the upper surface position of the patient platform 8 is always constant when the X-type frame is opened and folded. Briefly describing this structure, as shown in FIG. 5, when the X-shaped frame is in a state of being in a wheelchair and opened in the width direction, the lower end 10A of the X-shaped frame has a horizontal axis. 16 are arranged at substantially the same height. From this state, when the X-type frame is placed in the folded state in the width direction, the lower end 10A thereof moves downward from the shaft 16 to the position shown in FIG. Therefore, the position of the upper surface of the patient platform 8 is substantially the same as the height of the bed 34 without any change before folding. By adopting such a structure, it is possible to replace the patient 32 without moving it up and down. This structure is disclosed in Japanese Patent Application Laid-Open No. 2002-224166 filed by the present applicant.

  Furthermore, in the said Example, the X open leg type side surface separation apparatus is comprised so that the X type frame of the lower frame 10 can be opened in a width direction with a leg | foot. As shown in FIG. 1, this X-leg type lateral separation device is composed of, for example, a wire 36 and a ratchet mechanism (not shown), and an assistant repeatedly steps on the pedal 38 shown in FIG. As a result, the wire 36 is pulled so that the lower frame 10 can be opened to one side. In addition, this X-opening-type side separation device can be used selectively. By temporarily connecting and fixing the side surface of the lower frame 10 on the bed 34 side with the wheel 12 on the bed 34 side, it does not depend on the foot. It is also possible to open the lower frame 10 together with the stool 9 by pulling it forward with the arm.

  Below, although the effect | action of the wheelchair 20 with a transfer function by a present Example is demonstrated more concretely, in the following description, the case where the function of X open leg type side separation apparatus is not used is demonstrated.

Now, the wheelchair 20 with a transfer function has not yet developed the patient mounting base 8 in a long shape, and is in a normal wheelchair state. Patient 32 is lying on bed 34.
Thus, when the wheelchair 20 with a transfer function is in a wheelchair state, as shown in FIG. 3, the bar-like portion 3b not involved in the connection of the shaft bar handle 3 of the upper and lower bases 5 and 6 is It is passed to the lower surface side of 6 and functions as a stopper for the upper table 5.

Thus, the wheelchair 20 with a transfer function is brought closer to the side of the bed 34 from the state where the stopper is applied to the patient platform 8 as shown in FIG. The state shown in FIG. 5 is assumed to be an initial state.
As shown in FIG. 6 from the initial state described above, the lower frame 10 is manually contracted in the width direction (X direction approaching the bed 34). Then, the side surface of the lower frame 10 far from the bed is guided by the horizontal shaft 16 and the bearing box 24 as shown in FIG. 6, and approaches the bed 34 side while moving in the X direction. At this time, the end of the seat 9 that is far from the bed 34 moves in the X direction together with the horizontal plate 7 ′ that is far from the bed 34 of the lower frame 10. On the contrary, since the horizontal side plate portion 7 on the bed 34 side of the lower frame 10 is movable relative to the seat portion 9, in FIG. 6, when the seat portion 9 moves in the X direction. The position of the horizontal side plate portion 7 on the bed 34 side of the lower frame 10 moves relative to the seat portion 9 in the X ′ direction.

  In this way, a space 40 is formed between the wheel 12 ′ far from the bed 34 and the side surface far from the bed 34 of the lower frame 10. In addition, on the upper side, a sitting portion 9 including a base 5 and a base 6 below the patient platform 8 is disposed on the bed 34. Thereby, the first movement is completed (state shown in FIG. 6).

  Subsequent to this first movement, next, in order to remove the stopper function of the shaft handle 3, the rod-like portion 3b of the shaft handle 3 is flipped upward as indicated by the arrow in FIG. As a result, the stopper mechanism between the upper table 5 and the lower table 6 is released. In this state, the upper table 5 constituting the seat 9 can move with respect to the lower table 6.

  After releasing the stopper mechanism from the state of FIG. 6, if the base 5 on the seating portion 9 is lightly pushed in the X direction toward the bed 34 side, the upper base 5 is moved as shown in FIG. 1 or FIG. Move to bed 34 side. Therefore, the protruding length of the patient platform 8 relative to the bed 34 can be significantly increased. 1 and 7, the patient 32 can transfer from the bed 34 onto the patient table 8 by himself or with the assistance of an assistant. Since the assistant can enter the newly constructed space 40 at this time, the assistant can help from the side of the patient 32. Therefore, transfer work becomes easy. Thereafter, if the caregiver grasps the shaft handle 3 or the like and pulls out the seat portion 9 toward the front side, that is, the direction away from the bed 34, the upper table 5 on which the patient 32 is placed is placed on the lower table 6. Can be moved to. When this state is reached, the rod-like portion 3b of the shaft handle 3 is again rotated to the lower table 6 side to cause the upper table 5 to have a stopper function. Further, by pulling out the seat portion 9 partially resting on the lower frame 10 narrowed in the width direction together with the lower frame 10, the X-type frame of the lower frame 10 is attached to the pair of wheels 12, 12 ′. The seat 9 is fully opened, and the entire seat 9 is returned to the original state on the opened lower frame 10.

By arranging in this state, the transfer of the patient 32 is completely completed.
As described above, the method for extending the protruding length of the patient platform in the wheelchair with transfer function according to the embodiment of the present invention and the wheelchair with transfer function provided with this method have been described, but the present invention is limited to this. It is not a thing.

  For example, in the above embodiment, the case where the patient 32 is transferred from the bed 34 to the empty wheelchair 20 has been described. However, the present invention is not limited to this, and the patient 32 is placed on the bed 34 from the state where the patient 32 is placed on the wheelchair 20. The replacement can also be performed by following the reverse procedure.

Moreover, in the said Example, although the movement of the upper base 5 with respect to the lower base 6 was comprised by the roller fitting track | orbit 1 and the metal fitting 2 with a hole latched by this, this invention is not limited to this. Absent. For example, it is also possible to form a moving function by preparing two plate-shaped tables with low frictional resistance, arranging these tables up and down, and sliding them.

  Further, in the above-described embodiment, the lower frame 10 is provided with the X-spreading type side separation device including the wire 36 and the ratchet mechanism. is not. That is, the X-opening leg side separation device may not be provided in the lower frame 10.

Moreover, in the said Example, although the X-type frame which can be opened and closed is employ | adopted for the lower frame 10, the structure of the lower frame 10 is not limited to this.
For example, in the above-described embodiment, the X-type frames passed between the left and right side surfaces are installed vertically one by one in front and rear, but may be installed horizontally in the vertical direction and the movement allowance may be set horizontally. Even in the X-type frame having such a configuration, the upper surface position of the patient platform 8 can be made constant both when the X-type frame is opened and folded, as in the above embodiment. The frame may be placed horizontally.

  8 and 9 show a wheelchair with a transfer function disclosed in Japanese Patent No. 3003091, which has already been registered by the applicant of the present application. The wheelchair with a transfer function of this patent publication uses a lower frame that does not use an X-type frame. That is, if this wheelchair with a transfer function is demonstrated simply, the vertical support | pillar 52 will be arrange | positioned by the rail leg ring 70 with respect to the horizontal support | pillar 54 so that a movement is possible. In addition, on one side surface of a patient platform 56 having a backrest portion, there is provided a flat bed suspension 58 that also serves as a patient armrest and can be tilted sideways. When the bed bridge 58 is tilted from the vertical direction to the horizontal direction as shown in FIG. 9, the bed bridge 58 functions as a cradle for placing the patient cradle 56 and also has a function of braking the plurality of wheels 68 in conjunction with each other. doing. When the patient platform 56 shown in FIG. 9 is projected on the bed 34 as shown in FIG. 8, the back support bracket 60 is removed, and the bed bridge 58 is moved from the vertical direction to the horizontal direction. This is used as a cradle for placing the patient platform 56, and the vertical support column 52 is moved to the bed 34 side.

Even in a wheelchair with a transfer function having such a structure, a space 40 in which an assistant can enter is formed between the vertical support column 52 and the horizontal support column 54.
The method of the present invention can also be applied to a wheelchair having a lower frame structure as shown in FIGS. That is, the patient's stool portion, particularly the center portion, of the patient platform 56 may have a two-layer structure, and the upper table may be arranged to be movable with respect to the lower table. Even with such a structure, the protruding length of the patient platform can be made sufficiently long. Further, the assistant can approach the patient 32 from the side of the patient 32 by using the space 40 formed between the wheel 68 far from the bed 34 and the bed 34. Therefore, the labor for assistance can be significantly reduced.

  As described above, in each embodiment of the present invention, there is no structure in which a part of the lower frame enters the lower part of the bed and approaches the bed. Therefore, there is a medical device or a patient's luggage under the bed. Even if it is stored, it will not interfere with the work. In addition, since the lower frame is not structured to enter the lower part of the bed, it is not necessary to make all the wheels small, and a slightly larger wheel can be used for the rear wheel, so that it is possible to secure a riding comfort as a normal wheelchair.
