What is most required of such a patient transfer cart is that the structure is simple and easy to handle, and the patient can be safely and minimally labored without any pain. It is possible to transfer from bed to dolly and from dolly to bed. However, in the above-described conventional dolly, when the dolly is brought close to the patient, there is a risk that the bed may accidentally collide with the patient. Also, even if the bed is located above and approaches the patient, when the base frame is inserted into the lower part of the bed, the bed is above the patient, giving the patient a feeling of oppression or being mentally weak. There is a fear that the patient may feel fear. In addition, the structure tends to be complicated and the weight tends to be heavy, and since the bed is always kept in a horizontal state, even when the patient moves in the bed, the field of view in the vicinity of the carriage is narrowed, They had to move carefully and had the drawback of lacking urgency. Therefore, the present inventor has conducted various experiments to solve the above problems, and has a simple structure and is easy to handle, and is convenient for transportation, storage, and movement, and particularly when the carriage is approached to the patient's bed,
The present invention has devised a trolley that can give a sense of security to a patient without accidentally colliding with the patient and can safely transfer the patient with a minimum effort.

Close to bed 18 lying on the floor. At this time, the bed 4 is rotated around the shaft 13 to stand upright. In addition, in order to maintain the standing state, the bed 4 is tilted slightly toward the support frame 3 side from the vertical in this embodiment. Of course, the side portion of the bed 4 may be locked to the column frame 3 by a not-shown locking tool to keep the bed 4 in the upright state. Then, the pair of base frames 2 are inserted between the legs of the bed 18. Next, the patient 19 is rotated 90 degrees from the supine state to the horizontal state as shown in FIG. 5, and is positioned on the right side of the bed 18 in the figure. Then, the bed 4 is rotated horizontally, and the bed 4 is lowered to the upper surface of the bed 18. Then, the patient 19 is rotated leftward from the horizontal position to the supine position, and the patient 19 is transferred onto the bed 4 as shown in FIG. It should be noted that when the patient 19 is located near the edge of the bed 4, the bed sheet, blanket, etc., which is placed on the bed 4 in advance, is pulled to the left to facilitate the patient 19.
Can be moved to the center of the bed 4. next,
The bed 4 is raised and a fall prevention fence (not shown) is attached to the end of the bed 4. Next, the main carriage is moved from the solid line state to the chain line state. Next, the bed 4 is lowered, and the carriage is moved to a predetermined place at the stable lowest position.
Next, in order to transfer the patient 19 from the main carriage to the bed 18, the procedure reverse to the above procedure may be performed.

Next, as shown in FIG. 3, when a means for finely adjusting the position of the stopper 15 provided on the bed 4 is attached to the main carriage, the patient can be transferred more easily. That is, it becomes easy to transfer the patient 19 on the bed 18 to the center of the bed 4 as shown in FIGS. 8 and 10. That is, FIG.

According to the dolly for patient transfer of the present invention, the bed can be raised and lowered by the supporting means by the support means so that the other side of the bed moves around the one side of the bed and the other side rotates upward. Therefore, the patient can be safely transferred to the trolley without giving fear or pressure to the patient during transfer. That is, since the main carriage can approach the patient on the bed with the bed resting upward, there is no possibility that the tip of the bed rests against the patient by mistake. Then, with the base frame 2 fully inserted under the bed, place the bed on the bed,
The patient can be easily transferred to the bed while rolling over the patient while rotating. Next, after the use of the trolley, or before use, the bed can be swiftly moved by widening the field of view in the vicinity of the trolley by erecting the recumbent bed, and the trolley becomes a patient transfer trolley capable of coping with emergency cases. . Further, when the carts are stored, by raising the bed rest, it becomes possible to store a plurality of carts in a stacked manner, and the cart takes up less space.

Next, in the trolley according to the second aspect of the present invention, the bed is constructed so that the bed can be selectively set to either the horizontal position, the slightly lower tilt position, or the slightly upper tilt position. It is extremely easy to transfer the patient to the carriage and return the patient from the carriage to the bed. That is,
When the patient is transferred from the bed to the trolley, the patient can be easily transferred to the bed by setting the bed to the lower inclined position. The patient on the bed can then be very easily moved from its edge to the central position by placing the bed in the up-tilt position. Then, by returning the bed 4 to the horizontal position, the patient can be moved in a stable state. Further, according to the trolley of claim 3, since the base frame is configured to be expandable / contractible so as to reduce the width of the trolley as a whole, when the trolley is not used, the occupancy space is small. Saves space for storage.
