Abstract

PURPOSE:To enable the lifting or lowering of the body of a patient lying locally by rotating a link mechanism mounted before and after a leg base to lift or lower a body frame with vertical movement of a lift member while the body frame is rotated horizontally with respect to the lift member to incline the body frame horizontally. CONSTITUTION:For example, with a body frame 8 lowered, motors 6 and 7 of an actuator for lifting or lowering the body frame 8 are operated to push out working shafts 6a and 7a. As a result, links 15 and 16 turn outward centering on a pivot point with link legs 14 and 16 so that the link leg parts 23 and 24 are pushed up to lift the body frame 8. The body frame 8 comes down in the reversal of the procedure. The body frame 8 can be inclined by operating one alone of the link mechanisms 3 and 4. The motor 9b of the actuator 9 is operated to push or pull a working shaft 9a thereby enabling the tilting of the body frame 8 to the right or left with respect to the lift member 5.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bed for an intensive care unit, and more specifically, it can hold a patient sleeping in a bed in any posture according to his or her body, and The present invention relates to an intensive care unit bed in which a patient can easily load and unload.

[0002]

2. Description of the Related Art Conventionally, as a bed for an intensive care unit, there is a bed in which a main body frame having a floor portion can be raised and lowered. In the case of this elevating bed, it is possible to raise and lower the front and rear of the main body frame at the same time, that is, while keeping the main body frame in a horizontal state, and to raise and lower only the front portion or the rear portion of the main body frame independently. By doing so, the upper half of the patient's upper body and the lower half of the patient's upper body can be tilted according to the patient's sleeping condition.

[0003]

However, depending on the patient's condition, the body part of the sleeping patient may be partially localized, for example, only the right side of the upper body or the left side of the lower body. It is necessary to raise and lower, and in such a case, it is necessary to incline the body frame in three dimensions.
However, in the case of the conventional lifting bed, the front and rear portions of the body frame can only be raised and lowered as described above, and the body frame cannot be tilted three-dimensionally. Cannot take a proper posture. Also, in the case of a critically ill patient, loading and unloading onto a bed is difficult, but in the case of a bed where the main body frame simply moves up and down as in the conventional case, for example, a stretcher with the patient's local part raised is used. It was extremely difficult to transfer the operation table from the operating table to the bed or transfer the operation table from the bed to the operating table.

In view of the above-mentioned problems, the present invention is a bed for an intensive care unit in which the body frame of a bed having a floor can be tilted three-dimensionally at any angle. It is intended to provide a bed in which the patient's body is locally raised and lowered so that the patient can take an optimal posture according to his / her body, and the patient can be easily put on and off from any posture.

[0005]

In order to achieve the above-mentioned object, an intensive care unit bed according to the present invention is provided with a pedestal equipped with a moving means, which is provided in front of and behind the pedestal independently of each other. The lifting member is attached by a pair of moving link mechanisms, and the front and rear link mechanisms are rotated by an actuator provided between the lifting member and the front and rear members of the lifting member so that they can be raised and lowered independently of each other, A body frame having a floor portion is rotatably pivoted to the left and right on the elevating member, and the elevating member and the body frame are connected by an actuator at a position lateral to the axis of the rotating shaft. The body frame is attached to the lifting member so as to be tiltable left and right.

[0006]

The bed for the intensive care unit according to the present invention is configured as described above, and by rotating the link mechanism attached to the front and rear of the leg stand by each actuator,
The elevating member is moved up and down, and the main body frame attached to the elevating member is moved up and down. In this case, if the front and rear link mechanisms are independently rotated, only the front part or only the rear part of the main body frame can be moved up and down respectively. Can be moved up and down while it is horizontal. Further, the main body frame can be tilted left and right by rotating the main body frame to the left and right with respect to the elevating member by the actuator that connects the elevating member and the main body frame.
Furthermore, by combining the lifting operation of the lifting member by the front and rear link mechanism and the tilting operation of the main body frame to the left and right, the main body frame can be tilted three-dimensionally in the front-rear direction and the left-right direction according to the patient's condition. The patient can be kept in an optimal posture with any local position raised, and in this state, the patient can be treated in the intensive care unit and laid down in a rested state. It can be moved by moving means provided on the table. Also, when the patient is placed on the bed, the elevating member is moved up and down with respect to the leg stand and the main body frame is tilted to the left and right with respect to the elevating member in the same manner as described above. By tilting to, the patient can be picked up from an arbitrary position and from an arbitrary position, and can be placed on the bed or can be lowered from the bed.
