DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transport bed for nursing care used for carrying a patient on it.

[0002]

2. Description of the Related Art When transporting a patient who cannot get up to a toilet, a washroom, a bathroom, or the like, a transport bed for nursing care may be used.

A conventional transport bed is formed by setting a mat on a support frame, and casters are attached to legs of the support frame. So, this one
The patient can be moved parallel to the side of the bed on which the patient is sleeping, the patient can be moved laterally from the bed onto a mat, and the patient can be transported to a target location.

[0004]

According to the prior art, the support frame cannot adjust the height of the mat, so that when a patient is sleeping on a futon on the floor, the support frame can be used by a plurality of caregivers. The patient must be lifted and transferred onto the mat, which makes the transfer operation cumbersome,
There is a problem that work by one caregiver is difficult.

[0005] In view of the above-mentioned problems in the prior art, it is an object of the present invention to easily transfer and transport a patient by one caregiver by attaching a foldable leg member to a support frame. To provide a transport bed for nursing care.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, according to the present invention, there is provided a support frame on which a mat is mounted, a leg member provided with casters foldably attached to the support frame, and a support frame. The gist of the present invention is to provide a jack for pushing up.

The support frame has an arc-shaped support member on the lower surface, and the support member can form a storage space for storing the leg members and the jack. In addition, a damper is attached to the support frame, and the damper can urge the support frame upward.

[0008] Further, the support frame may have a backrest which can be turned upside down or a footrest which is inclined downward.

[0009] The leg member can be linked to the jack via a wire rope.

[0010]

According to the structure of the invention, the jack is
Since the support frame can be pushed up, the caregiver can operate the jack to raise and lower the support frame, thereby raising and lowering the patient to an arbitrary height position. That is, the patient can easily be transferred onto the mat of the support frame regardless of the height of the futon or bed on the floor, and can be transported to an arbitrary place via the casters of the leg members.

If the support frame is provided with a support member, the support frame can store the leg members and jacks in a storage space formed by the support member, and can be tilted laterally via the support member to support the patient. When the patient is transferred onto the mat of the frame, the transfer operation of the patient by the caregiver can be further simplified.

A damper for urging the support frame upwards includes:
The support frame is pushed upward together with the jack to reduce the operation force of the jack, and also prevents the descending speed from becoming excessive when the support frame is lowered.

[0013] The support frame having the backrest can erect the backrest and stably seat the patient.

The support frame having the footrest can lower the height of the patient's foot by tilting the footrest downward, and can put the patient in a comfortable posture.

If the leg member is linked to the jack, the leg member supports the support frame when raising and lowering the support frame via the jack, so that the stability of the support frame can be improved.
