First, a bathtub is lowered, a patient is placed above the bathtub, and then the bathtub is raised. A type of bathing a patient is provided. Here, when placing the patient above the bathtub, put the patient on a stretcher on a stretcher,
There is a case where a stretcher is laid sideways on a bathtub and the patient is moved horizontally above the bathtub together with the stretcher.

[0003]

By the way, the transfer and bathing of the patient are performed by the caregiver. When the patient is sent from the stretcher to the upper side of the bathtub as described above, the caregiver must lie sideways on the bathtub. Stand beside the stretcher and push the stretcher toward the bathtub to slide it. At this time, the abdomen and the like of the caregiver hit the stretcher on the stretcher as the stretcher is sent to the upper part of the bathtub, and the stretcher that is away from the caregiver from that state further pushes the stretcher toward the bathtub, and the stretcher becomes an obstacle. Forced posture is imposed. This is the same when returning a stretcher to a stretcher after taking a bath. This makes it difficult to slide the stretcher, increasing the burden on the caregiver.

[0004] The present invention has been made in view of the above circumstances, and an object of the present invention is to reduce the burden on a caregiver by facilitating the work of sending and returning a stretcher on a stretcher to an upper part of a bathtub. It is in. It is also an object of the present invention to enhance the degree of freedom in design, to be excellent in usability, and to provide a good seal so that hot water in the bathtub does not leak to the outside.

[0005]

The present invention achieves the above object by the following means. That is, a bathtub,
A guide member that receives a stretcher that is moved in a substantially horizontal direction from a stretcher adjacent to the bathtub and guides the stretcher to a bathing position above the bathtub, and the guide member is attached, and the stretcher is mounted via the guide member. A support base for supporting the bathtub in the upper center, and at least one of the support base and the bathtub is moved in the vertical direction to relatively separate and approach each other, and a bather placed on a stretcher when approaching is put in the bathtub. An elevating mechanism for taking a bath, and a stretcher drive mechanism for moving the stretcher between the stretcher and the bathing position along the guide member, wherein the stretcher drive mechanism engages with the stretcher. The portion is connected to a drive source via a flexible linear body, and the engaging portion is moved along the guide direction of the guide member by being pulled or pushed by the linear body. Characterized in that it is configured. According to the above invention, since the stretcher can be moved between the stretcher and the bathing device above the bathtub by the stretcher drive mechanism, the work of moving the stretcher becomes easy,
The burden on caregivers is reduced. In addition, since the engaging portion that engages with the stretcher is moved via the flexible linear body, the drive source can be arranged at an arbitrary position, and the degree of freedom in design is increased.

[0006] Further, the support for supporting the support table may be hollow, and a linear body may be inserted through the hollow portion. In this case, since the linear body is housed in the hollow part of the column,
It can be prevented from interfering with other components without being in the way, and is also easy to use because it does not easily touch the bather's body.

Further, a part of the linear body may be replaced with a rod member, and a seal mechanism may be provided outside the rod member. A sealing portion is required so that hot water does not flow outside when the linear body passes through the bathtub, but it is difficult to seal the linear body itself. Here, a part of the linear body is replaced with a rod member, and sealing is performed using this rod member.
Good sealing can be realized.

Further, the linear body may be provided with extra length absorbing means for absorbing an extra length of the linear body. Even if the linear body is loosened or the like, the extra length is absorbed by the extra length absorbing means, so that the engagement portion can be moved more reliably.

And the piston rod 150 is pushed up by a constant pressing force under hydraulic or pneumatic pressure, whereby the lifting intermediate rollers 134a and 134b are always urged upward with a constant pressing force. ing.
Therefore, for example, when the rail base 78 is moved up and down by the pantograph mechanism 123, if the extra length generated in the linear body 92 or the length of the linear body 92 is insufficient, the cylinder 150 automatically expands and contracts. Operate and adjust it. That is, when the rail base 78 is lowered,
The tensile force applied to the linear body 92 is weakened, and the cylinder 150 expands to absorb the extra length of the linear body 92, and conversely, the rail base 7
8 rises, the tensile force applied to the linear member 92 increases, and the tensile force acting on the linear member 92 acts on the cylinder 150 as a compressive force. Make up for the lack of 92 length.

Also in the second embodiment, the moving table 79 having the stopper 34B, which is an engaging portion for engaging with the stretcher 3, is provided.
However, since the stretcher drive mechanism 130 reciprocates between the stretcher devices 1 from above the bathtub 74, the caregiver sends the stretcher 3 from the stretcher device 1 to the bathtub 74 or returns the stretcher 3 to the stretcher device 1 slightly. And
And there is no need to force yourself. Therefore,
The work of moving the stretcher 3 is facilitated, and the burden on the caregiver is reduced. The caregiver's burden is reduced. Further, in the second embodiment, since the extra length absorbing means 110 is provided,
After the linear body 92 is connected to the projections 91a and 91b at both ends thereof and wound around several idle rollers between the driving roller 137 and the connecting portion to the projections, necessary tension adjustment is performed. In addition to easy work, even when the extra length of the linear body 92 or the length of the linear body 92 generated when the rail base 78 side is moved up and down by the elevating mechanism 120 is short, those problems are automatically detected. Can be absorbed and adjusted.

In the second embodiment, the pins 148 supporting the intermediate rollers 134a and 134b are constantly moved by the cylinder 150 to the right and left idle rollers 134a and 134b.
Although a certain tensile force is applied upward through the a and 134b, the present invention is not limited to this, and the pin 148 for supporting the elevating and lowering intermediate roller can be fixed upward by an elastic material such as a spring. It may be a structure to give. In the first and second embodiments, only the moving table 79 on the rail table 78 is configured to be movable in the left-right direction. However, the present invention is not limited to this, and the stopper 34B may be fixed to the rail table. Alternatively, the rail base 78 may be moved in the left-right direction.

As described above, according to the first aspect of the present invention, the stretcher is moved between the stretcher and the bathing position above the bathtub by the stretcher drive mechanism provided on the support base above the bathtub. Since it is possible to move the stretcher, the burden on the caregiver can be reduced. In addition, since the engagement portion with the stretcher is moved by the linear body, the drive source can be disposed at any position, and the degree of freedom in design is increased. According to the second aspect of the present invention, since the linear body is housed in the hollow portion of the support, it can be prevented from interfering with other components without being in the way and can be applied to the body of the bather. It is also easy to use because it is hard to touch. According to the third aspect of the present invention, a sealing portion is required so that hot water does not flow outside when the linear body passes through the bathtub, but it is difficult to seal the linear body itself. Here, since a part of the linear member is replaced with a rod member and the rod member is sealed, a good seal can be realized. According to the fourth aspect of the invention, even when the linear body is loosened or the like, the extra length is absorbed by the extra length absorbing means, so that the engagement portion can be reliably moved.
