Description

  The present invention relates to a technology of a transfer support apparatus that supports transfer of a cared person.

  It is not easy for a cared person who is difficult to walk independently to perform a transfer operation such as transfer from a bed to a wheelchair alone. For this reason, the caregiver's help is usually required. However, the help of the transfer is a physical burden for the caregiver and also a mental burden for the care recipient. For this reason, in recent years, many devices that support transfer operations of people who are difficult to stand on their own have been developed (for example, Patent Documents 1 to 3).

  Patent Document 1 discloses a device in which a body holding tool is provided at the tip of a column attached in a tiltable manner, and causes a cared person to be held in the body holding tool. However, in the state where the cared person is raised, the upper body is almost in a horizontal position, and the cared person places the entire weight on the body holder, and the chest and abdomen are strongly pressed, and the burden on the cared person is large.

  Patent Document 2 is to hold a cared person to a body holder as in Patent Document 1, but further includes a lift belt that supports the buttocks of the cared person. However, it is difficult to wear the lift belt that supports the buttocks when the cared person sits on the bed, which places a burden on the cared person and the caregiver. Furthermore, if it is mounted at an inappropriate position, the cared person may fall off the lift belt during operation, causing an accident.

  Patent Document 3 discloses a support device that includes a roller on a seating portion that supports a buttocks. However, in order for the cared person to sit on the seat, it is necessary to move the cared person's body. For example, even if the seating section is adjusted to the same height as the bed on which the cared person is seated and moved to the side of the bed, the cared person needs to be moved from the bed onto the seating section. Therefore, the work burden is placed on the care recipient and the caregiver.

  The present invention has been made in view of the situation as described above, and a problem to be solved is to provide a transfer support device capable of easily transferring a cared person in a sitting position.

  The problem to be solved by the present invention is as described above. Next, means for solving the problem will be described.

That is, in claim 1, a carriage part in which a plurality of freely rotating wheels are arranged at the bottom part,
A footrest that is placed on the cart and places the caregiver's foot;
A column that is disposed on the carriage unit, and is attached to be tilted by a hinge that is disposed closer to the buttock than the position of the ankle of the care recipient placed on the footrest,
A side abutting portion disposed on the column and abutting a side of the care recipient;
A shin abutment portion disposed on the support column and abutted on the shin portion of the care recipient;
It is a transfer / movement apparatus provided with the stopper which controls the inclination-angle of the said support | pillar.
The care receiver is supported by the side abutment portion and the shin contact portion disposed on the support column of the device, and the support column is tilted forward, so that the care receiver is tilted forward in a sitting position. Thus, the cared person's buttocks are evacuated slightly upward from the seating surface, and the cart section is moved in that state to enable easy transfer.

  According to a second aspect of the present invention, there is provided a transfer / moving apparatus characterized in that a grip portion for a caregiver to perform an operation is provided at a tip portion of the support column.

  As effects of the present invention, the following effects can be obtained.

  In claim 1, the cared person is moved to the seated part by supporting the cared person with the armpit part, the shin pad part, and the footrest, and not using the seating part or the lift belt that supports the buttocks. The work of passing a lift belt under the buttocks of the person becomes unnecessary, and the work burden on the care recipient and caregiver can be reduced.

  In claim 1, the cared person is supported by the armpit part, the shin pad part, and the footrest, but the hinge of the support column provided with the armpit part and the chin rest part is the position of the ankle of the cared person placed on the footrest. It is arrange | positioned rather than the collar part side. After placing the caregiver in the vertical position, tilt the prop to the front of the cared person around the hinge, and tilt the cared person forward in the sitting position, thereby Lift up the cared person's buttocks. At this time, because the hinge position of the support is on the buttock side from the ankle, the cared person supported by the armpit and shin contact parts will perform a fan-shaped movement horizontally downward around the hinge, Because it is tilted forward and diagonally down rather than lifted upward, the weight of the cared person will be distributed and borne by the armpit and his knees and waist, reducing the burden on the cared person's body be able to.

  In Claim 1, since the hinge of the support | pillar is arrange | positioned rather than the position of the ankle of the cared person placed on the footrest, the boarding was carried out by inclining the said support | pillar ahead of the cared person. If the cared person is tilted forward while in the sitting position, the center of gravity of the cared person moves forward from the hinge position, so the rotational force by the center of gravity becomes the force that presses the column against the stopper that regulates the tilt angle, and in the opposite direction There is no force to return to. That is, when the support column is tilted forward, it is not easily returned to the original position, and it is easy to maintain this position. Therefore, when moving the cart unit, the cared person is moved in a stable boarding state. be able to.

  According to the second aspect of the present invention, by providing a grip portion for the caregiver to perform an operation at the tip end portion of the support column, it becomes easier for the caregiver to tilt the support column and move the cart unit.

  FIG. 1 shows the overall configuration of a transfer support apparatus according to an embodiment of the present invention. FIG. 1 is a diagram for explaining an embodiment according to the present invention in relation to a cared person 20, a bed 10, and a wheelchair 11. This will be described below with reference to FIGS.

  FIG. 2 shows a state where a cared person who has taken a sitting posture on the bed 10 gets on the transfer support device. After preparing the wheelchair 11 to be transferred to the side of the bed 10, the transfer support device is placed on the front side of the cared person 20, and the armpit 6 is slowly inserted into the armpit of the cared person 20. Push it in. When the armpit 6 enters the armpit, the person to be cared 20 is placed on the footrest 3 and a part of the column 5 is gripped by hand, and the caregiver supports the transfer by holding the cart 2 with his feet. Secure the device. In addition, the thing with a stopper may be used for the free rotation wheel 1 installed in the bottom part of the said cart part 2 of the transfer assistance apparatus, and a transfer assistance apparatus may be fixed using it.

  In the state of FIG. 2, the caregiver slowly tilts the support column 5 and tilts the support column 5 until it hits the lower stopper 42. Accordingly, the cared person 20 is brought forward and the state shown in FIG. 3 is obtained. At this time, since the center of gravity of the cared person 20 moves to the front of the cared person 20 rather than the hinge 4, the rotational force due to the center of gravity becomes the force that presses the column 5 against the stopper 42 that regulates the tilt angle, and the force that returns in the opposite direction. Does not occur.

  In the state shown in FIG. 3, the caregiver releases the support device held by his / her toes (or removes the stopper of the freely rotating wheel 1) and moves the support device 20 on which the care receiver 20 is mounted. As shown in FIG. 4, it is rotated 90 degrees to a position where it is juxtaposed with the bed 10.

  The caregiver moves the wheelchair 11 prepared in advance to the transfer support device, and fixes the wheelchair 11 with the stopper of the wheelchair 11 at a position where the seat surface of the wheelchair 11 is directly below the buttocks of the care recipient 20. This state is shown in FIG.

  In the state of FIG. 5, the caregiver can once fix the transfer support device again, and then slowly tilt the column 5 to the vertical position to transfer the care receiver 20 to the wheelchair 11. This state is shown in FIG.

  When the cared person 20 can transfer to the wheelchair 11, the transfer assisting device is moved so that the armpit 6 is slowly pulled out from the armpit of the cared person 20. That is FIG.

  FIG. 8 shows a comparison between the position of the hinge 4 and the ankle 21 comparing the movement of tilting the body forward from the state where the cared person 20 is sitting. FIG. 8A shows the case of the present invention, and FIG. 8B shows the case where the hinge 4 is in front of the ankle 21. 8 (a1) shows only the movement of the cared person in FIG. 8 (a), and similarly FIG. 8 (b1) shows only the movement of the cared person in FIG. 8 (b). is there.

  8 (a) and (a1), the cared person 20 moves forward almost horizontally without being lifted upward, but in FIG. 8 (b) and (b1), the cared person 20 moves diagonally upward. Lifted. In addition, the angle of the knee 22 of the care recipient 20 at that time is larger at the angle B of (b1) than at the angle A of (a1). That is, in (a) and (a1), the angle of the knee remains unchanged while in the sitting position, but in (b) and (b1), the angle of the knee 22 gradually increases. Therefore, in (b) and (b1), the care receiver 21 is lifted upward and the angle of the knee 22 is gradually opened by tilting the column 5 forward. On the other hand, in (a) and (a1), by tilting the support column 5 forward, the knee moves in the horizontal direction while tilting the entire body while keeping the same posture as the sitting posture.

  As described above, when the position of the hinge 4 is in front of the ankle 22 which is different from that of the present invention, the knee 22 gradually extends when the care receiver 20 is tilted forward to lift the buttocks. As a result, it is a burden on the care recipient that the knee 22 supports a part of the body weight. This is because stretching a knee while supporting a part of the body weight is equivalent to an act of standing up, so that the care recipient who is weak in standing up has a heavy burden.

  In the case of the present invention, the knee 22 can be kept in the same shape because it is tilted in the sitting position. For a cared person 20 who is weak in standing up, supporting a part of his / her weight while keeping the knee 22 as it is is much less burdensome than doing the same operation while stretching the knee. As a result, it is possible to keep the posture of the cared person 20 floating the hip part for a certain period of time without using the mechanism that supports the hip part, thereby enabling transfer support that allows the cared person in the sitting position to be easily transferred. An apparatus can be provided.

  In the present embodiment, as described above, the transfer operation from the bed 10 to the wheelchair 11 has been described as an example on the premise of the support work of the caregiver. However, the fan-shaped motion of the column 5 of the transfer support device is an electrically driven actuator. It is easy to automate the entire movement by moving and freely driving the freely rotating wheel, and it is possible for the care recipient to perform transfer work by operating alone.
