Abstract

PURPOSE:To enable safe and comfortable transfer by reducing the pain imparted onto a patient and the risk of falling of a transfer assisting machine. CONSTITUTION:When the hip of a patient is lifted up by a lifting means 14, a kneepad 15 is moved substantially horizontally, and the kneepad 15 and a lifting arm 10 are interlocked with each other to push the knee of the patient pressed thereto into the back side. Thus, while the knee of the patient is stretched, the hip is made to float so that the hip of the patient can be lifted up even if the lifting means 14 is not strongly tensed, whereby the shifting amount between a chest pad 12 and the chest of the patient can be reduced so as to lighten the pain of the patient at the time of lifting.

Description

[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 been equipped with wheels provided on a frame, a footrest and a chest pad provided on the frame, a knee pad provided above the footrest, and a footrest 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 feet placed, knees placed on a knee pad, and chest placed on a chest pad. 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 place 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 belt-like lifting device are connected to the lifting arm, and the lifting arm and Raise the lifting device and lift the patient's buttocks. This allows the patient to place their feet on the footrest and
You will be riding the transfer care machine in a sitting position with your knees on the knee pads and your chest on the chest pads, so rotate the transfer care machine to face the wheelchair prepared next to the bed and sit in a sitting position. Push the wheelchair relatively below the patient's buttocks. Once 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 the conventional transfer care machine, 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 buttock will not rise if it is 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. When the lifting arm lifts up the patient's buttocks, the knees placed on 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 touching and chest against the chest pad, the lifting arm and lifting device are raised to lift the patient's buttocks. However, at that time, when the patient's knee pad is moved and the knee placed on it is pushed toward the back, the patient's buttocks extend along an arc centered on the connection between the lifting device and the lifting arm. begins to move upwards. In other words, when the knee is pushed into the back by the knee pad, the patient's buttock is lifted while the knee is extended, so the patient's buttock is raised without the need for the lifting device to be under high tension, thus increasing the patient's chest. It is possible to prevent the patient from being significantly displaced from the chest pad, thereby reducing pain to the patient, and also eliminating the risk of the patient falling off the transfer care machine.

By inserting the lifting tool 14 into a large hole and then moving it to a small hole from which the head cannot come out,
is detachably connected to the lifting arm 10. In addition,
Both ends of the lifting tool 14 do not need to be detachable, and only one end may be detachable, or it may be connected to the lifting arm 10 in a non-detachable manner. Further, it does not necessarily have to be in the form of a belt, but may be in the form of a corset that can be wrapped around the patient's waist. The knee pad 15 is provided above the footrest 4, and is integrally provided with sliding rods 21 at both ends thereof, as shown in FIG. Each sliding rod 21 is slidably passed through a guide pipe 22 provided at the lower end of the vertical portion 11B of the lifting arm 10 in the horizontal direction. A coil spring 23 wound around a sliding rod 21 is elastically loaded between the lifting arm 10 and the knee pad 15, and a stopper pin 24 provided on the sliding rod 21 is connected to the lifting arm 10.
The knee pad 15 is made to protrude to the right side in FIGS. 1 and 2 until it comes into contact with the knee pad 15. Furthermore, a conventionally known manual or electric jack 25 is provided between the lifting arm 10 and the frame 1, and the lifting arm 10 can be fixed at any swinging position relative to the frame 1 by this jack 25. There is. In addition, 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. At the lower end position, as shown in FIG. 2, the transfer care device is kept out of the way when it is 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, put the patient on bed 28.
and push the chair 27 of the transfer care machine into the space below the bed 28. Then, the patient's feet are placed on the footrest 4 of the transfer care machine, the patient's knees are placed on the knee rest pad 15, and the lifting tool 14 is placed on the lower part of the patient's waist, and the patient is seated on this. When this state is reached, the patient's chest is placed against the chest pad 12 and the lifting arm 10 is rotated counterclockwise in FIG. 2 by the jack 25 to raise the lifting tool 14. Since there is some slack, the patient's buttocks will not be lifted during the initial stage of lifting. During this time, the lifting arm 10
When the knee pad 15 is rotated in the counterclockwise direction in FIG. remains at approximately the initial position. Thereafter, when the lifting tool 14 becomes less loose, the knee pad 15 comes into contact with the lifting arm 10, so that the lifting arm 10 moves the knee pad 15 upward.
The knee that was placed on 5 will now be pushed into your back. When the knee is pushed towards the back side using the knee pad 15,
Even without being lifted by the lifting arm 10, the patient's buttocks will move upward on an arc centered on the connecting portion between the lifting tool 14 and the lifting arm 10 while the patient's knees are extended. In this way, when the knee pad 15 is used to push the knee toward the back, the knee stretches and the buttocks are lifted, making it possible to lift the buttocks without having to apply strong tension to the lifting device 14. This makes it possible to reduce the misalignment between the chest 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. In this way, the lifting tool 1
If you can lift the patient's buttocks off the bed 28 in step 4,
The patient rides the transfer care machine in a seated posture with his feet placed on the footrest 4, his knees against the knee pad 15, and his chest against 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. When the lifting arm 10 is lowered and the patient is seated on the wheelchair, the lifting device 14 is removed from the lifting arm 10, and the patient's feet are moved from the footrest 4 to the footrest of the wheelchair. Transfer work is completed. At this time, when it is necessary to move the patient over a relatively long distance using the transfer care machine, after pulling out the transfer care machine from the bed 28, the chair 27 is raised by the pantograph lifter 26, and the patient is seated on the chair 27. This allows the patient to be transported 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 relative to the frame 1. Figure 5
1 shows the main part of a second embodiment of the present invention. In this embodiment, a knee pad 15 is provided to be slidable in the horizontal direction on the frame 1 by a guide rod (not shown), and the knee pad 15 is Electric jack 31 installed on frame 1
It is possible to move forward and backward by. 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 lifting the lifting tool 14 by the lifting arm 10, turn on the switch.
Then, first, the electric jack 25 is operated and the lifting arm 10 raises the lifting tool 14, and the lifting arm 1
0 is raised by a predetermined amount, the electric jack 31 is activated by a signal from a sensor that detects this. As a result, the lifting tool 14 is raised by the electric jack 25, and at the same time, the knee pad 15 is moved forward by the electric jack 31. 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 alleviating the patient's pain caused by the misalignment. In addition, there is an effect that the risk of the patient falling off the transfer care machine can be eliminated.
