Description

Description: TECHNICAL FIELD The present invention relates to a nursing assistance robot for critically ill patients, and relates to a nursing assistance robot for a critically ill patient, and holds or holds a sleeping patient on a bed or a bed team, or a bath or toilet while holding the patient. Nursing assistance robot that can be moved to.

[Technical background of the invention and its problems]

The need for nursing care devices for critically ill patients has been screamed. Especially in the case of seriously ill patients,
It takes a great deal of labor for a nurse to take things such as taking a bath or moving to a toilet, and there is a particularly great need for a device for such nursing assistance. For this reason, a nursing assistance device including an overhead traveling hoist crane and a patient support belt suspended from the crane has been proposed for the nursing assistance of bedridden patients. However, in the case of this conventional nursing assistance device, since the patient's support part is a belt, the weight is concentrated on the armpits and thighs, and there is a problem that it cannot be used for a long time. There was a problem that it was not possible to move to any place because it was only along the rails installed in.

There has also been proposed a nursing assistance device in which a movable carriage is provided with a support, a hammock is suspended from the support, and a patient is placed on the hammock to weigh the patient. However, in the case of such a device, it is not possible to use it unless the hammock is inserted under the patient, but in order to insert the hammock under the patient's whole body, it is necessary to lift the patient and prepare for use. There was a problem that it required a lot of labor.

[Object of the Invention]

The present invention has been made in view of such a conventional problem, and can be moved to any place by a movable carriage, and further, in order to support a patient, the left and right arms are individually provided. It is an object of the present invention to provide a nursing assistance robot that uses a provided support plate to support a patient in a large area and does not cause much discomfort even when used for a long time.

[Structure of Invention]

In view of the conventional problems as described above, the present invention provides left and right frames erected on a movable base so as to be position-adjustable and fixed in the left-right direction, and the brackets provided in the respective frames so as to be vertically movable. A vertical actuating device for moving up and down is provided in each of the frames, and at the tip of each L-shaped arm whose base side is rotatably fixed to each of the longitudinal support shafts provided in each of the brackets, A wrist rotation member is rotatably fixed around the axis in the left-right direction, and each patient support plate supported by each wrist rotation member is rotated around the axis perpendicular to the rotation axis of the wrist rotation member. In addition to being rotatably provided, each patient support plate is formed in an arc shape around the rotation axis of the wrist rotation member.

Example of Invention

The accompanying drawings show an embodiment of the present invention.
As shown in FIGS. 3 to 3, two left and right frames 5 and 7 are erected as columns on a base 3 that can run freely in any direction by casters 1.

The base 3 is composed of a long substantially C-shaped angle member, and the adjusting channel members 13 and 15 are telescopically fitted to the left and right legs 9 and 11 extending in the front-rear direction, respectively, and the handles 17 and 19 are provided. The adjustment channel members 13 and 15 can be adjusted back and forth by adjusting. The left and right body frames 5, 7 are connected to the base 21 extending in the left and right direction of the base 3 so as to be slidable in the left and right directions, and the body frames 5, 7 are adjusted by adjusting the handles 23, 25. You can adjust the interval of.

Brackets 27, 2 are provided on the left and right body frames 5, 7, respectively.
9 is provided so that it can move up and down, and each bracket 27, 28
L-shaped arms 31 and 3 are attached to the support shaft in the front-back direction provided on the
A base portion 3 is attached so as to be rotatable and fixed about the support shaft, and lock handles 35 and 37 can be fixed and rotated at predetermined angles, respectively.

A wrist rotation member 39, is attached to each tip of the left and right arms 31, 33.
41 is attached by lock handles 43 and 45 so as to be rotatable and fixed. And each of these wrist rotation members 39,
Patient support plates 47, 49 are rotatably attached to 41. As shown in detail in FIG. 2, the patient support plates 47 and 49 are bent to have substantially the same curvature as an arc of a circle whose center axis is the rotation center of the wrist rotation members 39 and 41. Further, the patient support plates 47, 49 are provided with handles 51, 53 for rotation thereof, so that the operation for inserting the patient support plates 47, 49 under the patient can be facilitated.

The springs 55 and 57 which are locked to the wrist rotation members 39 and 41 have the patient support plates 47 and 49 in the state shown by the two-dot chain line in FIG. 2 with the wrist rotation members 39 and 41 as the center. It is for supporting.

Brackets 27, 29 for mounting the arms 31, 33
Is a vertically moving device for vertically moving the brackets 27 and 29, and can be vertically driven individually by cylinder mechanisms 59 and 61 attached to the left and right body frames 5 and 7, respectively. The cylinder mechanism 5
The hydraulic unit 63 for driving the 9, 61 main body frame 5,
It is provided on the back of 7.

Further, the patient support plates 47 and 49 are rotatable about the wrist rotation members 39 and 41, respectively, as shown in FIG. 5, so that the patient support plates 47 and 49 can be inserted below the patient from both the front side and the opposite side of the patient. It can rotate 180 degrees around R. Further, as shown in FIG. 6, this patient support plate 47,
A backrest plate 65 is connectable to each of the pins 49 by a pin 67, and can be connected to either the right side support plate 47 or the left side support plate 49 depending on the orientation of the patient C lying on the bed B. .

The operation of the nursing assistance robot having the above configuration will be described below. As shown in FIGS. 1 to 3, when the patient C lying on the bed B is to be held up, the caster 1 is rotated and the legs 9 and 11 of the base 3 are placed on the bed B. Under the bottom of the bed, and the left and right body frames 5,
Move so that 7 comes.

Subsequently, the height positions of the arms 31 and 33 are adjusted by the operations of the left and right cylinder mechanisms 59 and 61. Then, as shown by the two-dot chain line in FIG. 2, from the state where the left and right patient support plates 47, 49 are flipped up, hold the handles 51, 53 and rotate the support plates 47, 49 along the θ axis. , Insert below patient C. When the left and right patient support plates 47 and 49 are inserted into the lower side of the patient C as shown in FIGS. 1 to 3, the cylinder mechanisms 59 and 61 are subsequently driven to horizontally support the patient. It is lifted up to and held up. Then, by moving the base 3, the patient can be moved to a toilet, bath or other place.

When it is necessary to adjust the distance between the support plates 47 and 49 by the height of the patient C, loosen the handles 23 and 26 and slide the left and right body frames 5 and 7 to the left and right with respect to the base portion 21 of the base 3. Spacing can be adjusted.

In addition, when the patient C is not lying on the bed B but on the floor, there is a brim and therefore, if the legs 9 and 11 of the base 3 are largely projected forward, it will hinder the handling of the patient C. Therefore, the adjustment channel members 13 and 15 can be contracted by the operation of the handles 17 and 19 so as not to get in the way.

When holding the patient C, as shown in FIG. 4, the left and right arms 31 and 33 are rotated in the Sl and Sr directions by operating the lock handles 35 and 37, respectively, so that both patient support plates 47 and 49 are angled. Turn on. Further, the backrest plate 65 is connected to the support plate 47 on the side of the patient C so that the patient C can take a comfortable posture.

If the support plates 47, 49 may collide when the left and right arms 31, 33 are rotated, the rotation shafts of the arms 31, 33 should be previously displaced in the design as shown in FIG. It is good to put it.
