Various things have been proposed so far. The current status of commercial products is
Self-propelled lift devices and waist belt support devices are the mainstream for home use, and ceiling fixed lift devices (for one room with several floors) are the mainstream for facilities.

Although such a transfer assisting device is commercially available, it is rarely used in the field of nursing care for some reason, and in many cases the caregiver still holds the assisted person and transfers them. The lifting action is to face the person in front of the person being assisted, to make the person lean on the person's chest in a slightly depressed posture, and then move his hips upward to push up his chest. Is. Although it is easy to avoid the risk of low back pain by making sure movement of the lower back center of gravity, many backers suffer from low back pain due to differences in height and weight.

[0004]

In the conventional transfer assisting device, the lift device for suspending and transferring the assisted person gives the assisted person an unpleasant feeling, and the assisted person is an object. It is not preferable from the viewpoint of ensuring dignity because it is close to handling as. Furthermore, there are problems with housing conditions and storability. On the other hand, the waist belt support device gradually guides transfer to a wheelchair or the like while supporting the seated person at the bedside by rotating the belt around the waist of the person being assisted. Must move by other means.

Since such a transfer assistance device is only an intermediary device between the bed and the wheelchair, the equipment cost is increased in addition to the bed and the wheelchair.

In view of the above problems, the first aspect of the present invention
The problem is to provide a carrier that does not give a sense of fear, can guarantee dignity, and can easily carry a person being assisted and run on a bedside. A second object of the present invention is to provide a wheelchair that does not give a feeling of fear, can secure dignity, and can assist transfer by a simple operation.

[0007]

In order to solve the first problem, the first means of the present invention is a sitting chair type carrier for assistance. In other words, this seat-chair type carrier for assisting uses a seat chair configured to crawl on the bedside of the person being assisted while keeping the sitting posture of the person being assisted by the power of the bedside. It is characterized by

[0008] When moving a person in a flat position on a bedside position, an assisting chair-type carrier is placed on the bedside surface, the person being assisted is erected in a sitting position, and from behind the person being assisted. Insert the seat plate of the assisting chair-type carrier between the buttocks and the bed surface and scoop it on the seat. As a result, it is possible to easily move on the bed surface while maintaining the sitting posture, and it is possible to mount the wheelchair as it is as a seat portion.

However, it is not easy to completely scoop the buttocks of the person being assisted in a sitting position onto the seat plate in this assisting chair-type carrier.

Therefore, this seat chair is an assembly type seat chair having a backrest member and a backrest portion main body which is detachable from the backrest member.

[0011] First, the person being laid flat on the bed surface is temporarily placed in a recumbent posture, and then the buttocks member (seat plate member) is applied to the buttocks to return to the recumbent posture. Buttocks can be laid. It can also be applied to diaper users and patients with rubbing on the floor. Next, the person is raised from a lying position to a sitting position, and the backrest portion main body is attached to the buttocks member to assemble. Thereby, the person being assisted can be held in a sitting posture. Even on a soft reclining surface covered with a futon, a caregiver can crawl the assembled seat chair manually or by power to hang it between the edge of the bed and the recumbent position ( It can be easily moved without floating. Dignity can be secured without giving fear.

[0012] When the person being assisted, which is held in the sitting chair type carrier in the sitting position, is laid on the bedside in the lying position, the above operations may be performed in reverse order.

The buttocks member is a sled member or a bed-side contact carrier such as a shredded member, and can be formed of a low friction plastic molded product. Relatively large wheel 1 or 2 that is difficult to sink into the futon
The above rolling wheels may be provided. The contact surface with the bed surface is preferably formed by a smooth curved surface. Friction can be reduced.
The shape of the smooth curved surface can be optimized in consideration of easiness of going straight, moving backward and turning. You may form a parallel sliding surface part like a ski. Furthermore, when equipped with a seat belt,
Helps to maintain the sitting posture of the person being assisted.

The buttocks member has an insertion hole (engaged portion), and the backrest main body has a seat receiving member (engagement portion) which can be inserted into and removed from the insertion hole. Is preferred. This is because the male and female fitting can realize one-touch (one-shot) assembling operation and avoid complicated assembling operation with a large number of assembling. There may be a male member on the buttocks member side and a female member on the backrest body side, but it is difficult to perform the insertion operation, and when the buttocks member is applied to the buttocks of the person being assisted, the backrest part The male member on the main body side is easy to get in the way.

The first buttress member can be slightly extended below the bottom surface in conjunction with the insertion movement of the seat receiving member into the insertion hole.
If you have the automatic feeding wheel of the
Since the automatic delivery wheel of is automatically delivered, the mobility on the bed after that is improved and the operation becomes easier. Of course, since the feeding operation itself is unnecessary, the operation load on the caregiver can be reduced.

Further, in the case of having an automatic connecting device for interconnecting the buttocks member and the backrest portion main body in conjunction with the insertion movement of the seat receiving member into the insertion hole, the caregiver grasps the backrest portion main body. It is possible to avoid the risk of slipping out of the buttocks member and rattling even if the robot is maneuvered. Of course, since the connection operation itself is unnecessary, the operation load on the caregiver can be reduced.

Further, in the case where the backrest body is composed of the seat receiving member and the backrest member connected so as to be tiltable, the backrest member is not laid down on the recumbent floor surface, and the person being assisted is raised. Since the seat receiving member can be easily inserted into the insertion hole, the operation load on the caregiver can be reduced.

It is preferable to have a backrest angle changing device capable of adjusting and locking the backrest angle of the backrest member. It is possible to reduce the support load on the caregiver when the person being assisted is raised to the sitting posture, and to change the sitting posture maintenance according to the person being assisted.

In the case where an automatic backrest unlocking device for releasing the lock mechanism of the backrest angle changing device is provided in association with the insertion movement of the seat receiving member into the insertion hole, the backrest after the insertion operation is carried out. When performing the upright tilting operation of the member,
It is possible to eliminate the unlocking operation of the lock mechanism and reduce the operation load on the caregiver.

Further, when the backrest part has an automatic pivoting armrest member that relatively folds and folds in conjunction with its own upright tilt and fall tilt, the armrest member reliably holds the sitting posture. Since it is possible to eliminate the folding operation and folding operation of the armrest member,
The operation load on the caregiver can be reduced.

Further, when the buttocks member has a second automatic feeding wheel that can be slightly extended below the bottom surface in conjunction with the standing and tilting of the backrest, the second automatic feeding wheel is automatically operated simultaneously with the standing and tilting operation. Since it is delivered to, the mobility on the bed after that is further improved, and the operation becomes easier. Of course, since the feeding operation itself is unnecessary, the operation load on the caregiver can be reduced.

In the case of having a shoulder band for towing or hanging, the operation on the bed can be facilitated because the pulling on the bed can use the force of the shoulder, and it can also be used as a hanging chair stretcher. It will be possible.

In the case where the assembly type chair has a vibrating device for vibrating the buttocks, since static friction when the bed surface is moved disappears, it is sufficient to always apply force against dynamic friction, which is easy with human power. Can be moved to. If the contact surface of the buttocks member is formed into an unequal wave surface such as a sawtooth shape (washing plate shape) so that a minute stroke of nodal motion is generated in one direction in synchronization with vibration, manual operation becomes very easy. . A vibration direction variable type vibration device is provided to change the vibration direction, and a pair of left and right vibration devices is provided to stop or damp the vibration of one vibration device in comparison with the vibration of the other vibration device. It is possible to turn or move a curve.

In order to solve the second problem, the second aspect of the present invention
The means is in a seat part detachable wheelchair using the above-mentioned assistance seat chair type carrier as a seat part. That is, this seat part detachable wheelchair comprises the above-mentioned assistance seat chair type carrier and a bridge member which can be extended from the vacant seat part side of the wheelchair body onto the recumbent floor surface to form the traffic surface of the seat chair type carrier. And a guide member for guiding the movement of the seat-chair type carrier on the bridge member, and a mounting device for fixing or releasing the seat chair in the empty seat portion.

Since the chair-type carrier can come and go via the bridge member extended from the empty seat side of the wheelchair body to the bedside surface, the chair-type carrier holding the person being assisted in a sitting position is lying down. It can be easily carried from the surface to the vacant seat of the wheelchair, and conversely, from the wheelchair to the bedside. In particular, since the guide member is provided, smooth traffic and safety can be ensured through the bridging member. It is preferable that the chair-type carrier has an engaging portion that engages with the guide member.

Since the seat-chair type carrier is fixed in the empty seat portion by the mounting device, it can be used as a normal wheelchair. For this reason, it is not necessary to use a dedicated transfer assisting device only for transferring, so that the introduction cost can be significantly reduced.

When this wheelchair main body is provided with the seat portion elevating / lowering device, the reclining surface and the seating surface can be made flush with each other, and further integrity can be secured. It is also possible to transfer between the wheelchair and the bath scene or tatami mat, or between the wheelchair and the passenger seat of the vehicle.
