[Detailed description of the invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transfer care machine, and more particularly to a transfer care machine used for transferring a patient from a bed to a wheelchair, for example.

[Prior Art] Conventionally, a transfer care machine has wheels provided on a frame, a footrest and a chest pad provided on the frame, a knee pad provided above the footrest, and a knee pad provided on the frame. a lifting arm that can be moved up and down, a lifting device connected to the lifting arm to lift the patient's buttocks, and a fixing means for fixing the lifting arm to the frame at a desired lifting/lowering position; There is a known device in which the patient's buttocks are lifted by the above-mentioned lifting device while the patient is sitting in a sitting position with the patient's legs placed, knees placed on the knee pads, and chest placed on the chest pads. With this type of transfer care machine, for example, when transferring a patient from a bed to a wheelchair, the patient is first seated on the edge of the bed, then placed on the footrest of the transfer care machine, and then placed on the patient's knees. Have them put their knees on the pad. Next, a belt-like lifting device is applied to the lower part of the waist so that the person can sit on it, and both ends of the lifting device are connected to the lifting arm, and the lifting arm and Raise the lifting device and lift the patient's buttocks. As a result, the patient will ride the transfer care machine in a seated position with their feet on the footrest, their knees against the knee pads, and their chest against the chest pads. The patient faces the wheelchair prepared next to the bed, and pushes the wheelchair relatively under the buttocks of the patient who is sitting in a sitting position. After the lifting arm is lowered and the patient is seated on the wheelchair, the lifting tool is removed from the lifting arm and the patient's feet are moved to the footrest of the wheelchair, completing the transfer from the bed to the wheelchair.

[Problems to be Solved by the Invention] In conventional transfer care machines, the patient's buttocks are lifted by raising the lifting device by raising the lifting arm, but the lifting device becomes loose at the beginning of the lifting arm. The patient's buttocks will not rise if they are removed, but the patient's buttocks will rise only after the lifting device is tightened strongly. As a result, the patient's chest began to deviate significantly from the chest pad, posing a risk of causing pain to the patient or falling off the transfer care machine. In view of such circumstances, the present invention provides a transfer care machine that enables safer and more comfortable transfers.

[Means for Solving the Problems] That is, the present invention provides the above-mentioned conventional transfer care machine, in which the knee pad is provided on the frame so as to be movable in a substantially horizontal direction, and the knee pad and the lifting arm are connected to each other. In conjunction with this, when the patient's buttocks are lifted by the lifting arm, the knees that are in contact with the knee pads are pushed into the patient's back.

[Function] According to the above configuration, for example, when placing a patient sitting on a bed on the transfer care machine, the patient's feet are placed on the footrest of the transfer care machine and the knee pads are placed on the patient's feet, as in the conventional case. With the patient's knees in contact and the patient's chest in contact with the chest pad, the lifting arm and lifting tool are raised to lift the patient's buttocks. However, at that time, when the above-mentioned knee pad is moved and the knee placed on it is pushed toward the back, the patient's buttocks will extend on an arc centered on the connection between the lifting tool and the lifting arm. begins to move upwards. In other words, when the knee pad is used to push the patient's knee toward the back, the patient's buttocks will be raised while the knees are extended, so the patient's buttocks will rise even if the lifting device is not under strong tension. As a result, it is possible to prevent the patient's chest from being largely displaced from the chest pad, thereby reducing pain to the patient, and eliminating the risk of falling off the transfer care machine.

A coil spring 23 wound around the knee pad 15 is loaded with a coil spring 23 wound around the knee pad 15, and the knee pad 15 is projected to the right side in FIGS. There is. Furthermore, a conventionally known manual or electric jack 25 is provided between the lifting arm 10 and the frame 1, and the jack 25 allows the lifting arm 10 to be fixed at any swinging position relative to the frame 1. I have to. Further, a chair 27 is provided on the right side of the footrest 4 and is raised and lowered by a pantograph lifter 26, and in the raised position of the chair 27, a patient placed on the transfer care machine can sit on the chair 27. I can,
At the lower end position, as shown in FIG. 2, the transfer and care device does not get in the way when pushed into the lower space of the bed 28. The pantograph type lifter 26 and the chair 27 can be easily removed from the transfer care machine if necessary. In the above configuration, for example, when transferring a patient from the bed 28 to a wheelchair (not shown), first the lifting arm 10 is positioned at the lower end position using the jack 25, and the chair 27 is positioned at the lower end position. In this state, the patient is seated on the edge of the bed 28, and the chair 27 of the transfer care machine is pushed into the space below the bed 28. Then, transfer the patient's legs to the footrest 4 of the nursing care machine.
At the same time, the patient is made to put his/her knee on the knee pad 15, and the lifting tool 14 is placed on the lower part of the patient's waist, and the patient is made to sit on this. When this condition occurs, place the chest pad 1 on the patient's chest.
2, the lifting arm 10 is rotated counterclockwise in FIG. 2 by the jack 25, and the lifting tool 14 is raised. is never lifted. During this time, when the lifting arm 10 is rotated counterclockwise in FIG. 2, the knee pad 15 also immediately tries to move to the right.
At the initial stage of lifting, the coil spring 23 is compressed by the patient's weight, so the knee pad 15
remains at approximately the initial position. After this, when the lifting tool 14 becomes less loose, the knee pad 15 comes into contact with the lifting arm 10, so that the knee placed on the knee pad 15 is pushed toward the back by the lifting arm 10. become. When the patient's knee is pushed into the back side by the knee pad 15, the patient's buttock is moved by the lifting device 14 while the knee is extended, even without being lifted by the lifting arm 10.
The lifting arm 10 moves upward along an arc centered on the connecting portion between the lifting arm 10 and the lifting arm 10. in this way,
When the knee pads 15 are used to push the knees toward the back, the knees stretch and the buttocks are lifted, making it possible to lift the buttocks without having to apply strong tension to the lifting device 14. It is possible to reduce the misalignment between the pad 12 and the patient's chest, thereby alleviating the patient's pain, and also eliminating the risk of the patient falling off the transfer care machine. If the patient's buttocks can be lifted off the bed 28 using the lifting device 14 in this way, the patient can place his or her feet on the footrest 4 and place the knee pads 15 on the floor.
The patient rides the transfer care machine in a sitting position with his knees resting on the chest pad 12 and his chest resting on the chest pad 12. When this state is reached, the transfer care device is pulled out from the bed 28, and the transfer care device is rotated to face a wheelchair (not shown) prepared next to the bed 28, and the wheelchair is placed below the buttocks of the patient in a sitting position. Push relatively. And the above-mentioned lifting arm 10
When the patient is seated on the wheelchair, the lifting device 14 is removed from the lifting arm 10, and
When the patient's feet are moved from the footrest 4 to the footrest of the wheelchair, the transfer from the bed to the wheelchair is completed. At this time, when it is necessary to move the patient over a relatively long distance using the transfer care machine, after the transfer care machine is pulled out from the bed 28, the chair 27 is raised by the pantograph lifter 26 and the patient is moved to the chair 27. If the patient is seated on a chair, the patient can be moved over long distances without causing pain. Note that the jack 25 may have any configuration as long as it can fix the lifting arm 10 at an appropriate moving position with respect to the frame 1. FIG. 5 shows the main parts of a second embodiment of the present invention. In this embodiment, a knee pad 15 is provided so as to be slidable in the horizontal direction on the frame 1 by means of a guide rod (not shown), and The pad 15 can be moved forward and backward by an electric jack 31 provided on the frame 1. In this embodiment, although not shown, the lifting arm 10 can also be raised and lowered by an electric jack 25, so that both electric jacks 25 and 31 can be controlled by a common switch. When the lifting arm 10 lifts the lifting tool 14, when the switch is turned on, the electric jack 25 is first activated and the lifting arm 10 is lifted.
When the lifting tool 14 is raised and the lifting arm 10 is raised by a predetermined amount, the electric jack 31 is activated by a signal from a sensor that detects this.
This allows the electric jack 25 to lift the lifting tool 14.
At the same time as the knee pad 15 is raised, the electric jack 31 moves the knee pad 15 forward. Therefore, it is clear that the same effects as those of the above-mentioned embodiments can be obtained in this embodiment as well. In the above embodiment, the lifting arm 10 is raised and lowered by swinging, but it goes without saying that it may be raised and lowered along the vertical portion 2B of the pipe 2. Further, as the chair 27, a normal chair with legs without a lifter may be provided to be detachably attached to the transfer care machine.

[Effects of the Invention] As described above, according to the present invention, it is possible to reduce the misalignment between the chest pad and the patient's chest when lifting the patient's buttocks with the lifting tool, thereby reducing the patient's pain due to the misalignment. In addition, there is an effect that the risk of the patient falling off the transfer care machine can be eliminated.
