Abstract

(57) [Summary] [Purpose] When using a wheelchair as a moving bed,
The patient can be moved to and from the bed in which the patient is moved without burdening the caregiver. [Structure] A hydraulic pump 7 and a hydraulic cylinder 8 are provided below a sitting portion 2 of a wheelchair 1. When the stool portion 2 is raised by the hydraulic cylinder 8 to be changed to the moving bed 1 ', the height of the moving bed 1'is adjusted to the same height as the bed 18 for moving the patient by the hydraulic pump 7.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a wheelchair that can be converted into a moving bed while a patient is sitting on it.

[0002]

[Prior Art]

 In general, wheelchairs that can be changed to a moving bed are used for the movement of people with physical disabilities (hereinafter referred to as patients) such as critically ill patients and the elderly. In this case, the patient, who is normally resting in bed, is transferred to a wheelchair by an attendant such as a nurse or an attendant, then changed to a moving bed and moved for treatment, walking, etc. When is finished, it is returned to the bed by the attendant again.

The seated portion of the wheelchair patient, which is used for such a purpose, is usually lower than the height of the bed. This requires the attendant to move the patient between the bed and the wheelchair considerably.

[0004]

[Problems to be solved by the device]

 As described above, in the conventional wheelchair, since the height is different from that of the bed, there is a problem that an attendant such as a nurse puts a considerable burden on moving the patient to and from the bed.

Particularly when the patient is a large person or an obese person, the caregiver must perform a considerable amount of hard work to support the patient, which is likely to cause back pain and the like, which causes a shortage of nurses. Is one of the reasons.

The present invention has been made in consideration of the above problems, and an object thereof is to provide a wheelchair capable of moving a patient to and from a bed without burdening an attendant. To do.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention is a wheelchair that can be converted into a moving bed, and a seat portion on which a patient sits when used as a moving bed is adjusted to the same height as a bed for moving the patient. It is characterized in that it has a height adjusting means.

[0008]

[Action]

 By having the height adjusting means for adjusting the height to the same height as the bed for moving the patient, the height of the seated portion of the wheelchair can be easily adjusted. Therefore, the patient can be moved to and from the bed without burdening the caregiver.

[0009]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. 1 to 3 show an embodiment of a wheelchair of the present invention, FIG. 1 is a side view, FIG. 2 is a plan view, and FIG. 3 is a rear view. The wheelchair 1 of the present embodiment has a seat portion 2 on which a patient sits, a backrest portion 3 and a handle portion 4.

Further, 5 is a car that rotates on the floor surface 6 to move the whole, 7 is a hydraulic pump having a first cylinder 8 provided below the stool portion 2 and in contact with the stool portion 2, and 9 is a backrest. A support member provided on the back surface of the portion 3, 10 is a second cylinder provided between the support member 9 and the support mechanism 11, 12 is a rotation preventing guide bar, 13 is a pump pedal, and 14 is a handle portion. The lever for hydraulic relief valve provided in 4 and 15 are footrests. The hydraulic pump 7, the first cylinder 8 and the second cylinder 10 are connected as shown in FIG.

As shown in FIG. 5, when the wheelchair 1 is used as a normal wheelchair, an attendant 17 grips the handle portion 4 and moves the patient 16 while the patient 16 is seated on the seat portion 2. The structure of the wheelchair 1 in this case is arranged as shown by the solid line in FIG.

When the attendant 17 depresses the pump pedal 13 while the wheelchair 1 is moving, hydraulic pressure is supplied from the hydraulic pump 7 to the first and second cylinders 8 and 10, so that the stool portion 2 is raised and the backrest is lifted. Since the part 3 falls backward and the footrest 15 extends, the structure of the wheelchair 1 has a flat arrangement as shown by the chain line. As a result, as shown in FIG. 6, the wheelchair can be changed to a moving bed (stretcher) 1'when the wheelchair is moving. The height can be adjusted by controlling the hydraulic pressure by the number of times the pump pedal 13 is depressed.

Next, in order to move the patient 16 from the moving bed 1 ′ to the bed 18, the height of the moving bed 1 ′ is adjusted to be equal to the height of the bed 18 as shown in FIG. The patient 16 can easily move to the bed 18 by rolling over (about 2 turns).

As described above, according to the present embodiment, in the wheelchair 1 that can be changed to the moving bed 1 ′, the height of the flat portion including the sitting portion 2 on which the patient 16 sits moves the bed for moving the patient 16. Since the height can be adjusted to be the same as that of the wheelchair 18, when moving the patient 16 between the wheelchair 1 and the bed 18, the caregiver 17 can be easily moved without burdening the caregiver 17.

That is, since the patient 16 can move by rolling over by himself, the caregiver 17 only needs to push it lightly, so that it is not necessary to perform heavy work as in the conventional case. For example, even in a critically ill patient who has difficulty in turning over, it moves on the same height plane, so there is no need for a pushing force based on the difference in height as in the past.

To return from the moving bed 1 ′ to the wheelchair 1, by operating the hydraulic relief valve lever 14 provided on the handle portion 4, the hydraulic pressure of the hydraulic pump 7 is gradually released, and the sitting portion The part including 2 returns to the position shown by the solid line in FIG.

In this embodiment, the means using hydraulic pressure as means for adjusting the height of the moving bed has been described, but the present invention is not limited to this, and an elevating mechanism using a motor or the like may be used.

[0018]

[Effect of the device]

 As described above, according to the present invention, in the wheelchair that can be changed to the moving bed, the height of the moving bed can be adjusted to the same height as the bed for moving the patient, which imposes a burden on the attendant. It is possible to provide a wheelchair that can easily move the patient to and from the bed.
