DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a medical facility such as a hospital or a place such as a care center requiring care for the aged, etc., without giving any burden to a patient or a caregiver who is sleeping on a bed. The present invention relates to a care support device capable of moving a patient as it is to a desired place.

[0002]

2. Description of the Related Art Conventionally, in hospitals and the like at medical sites,
When transferring a patient lying in bed to a desired location, two methods have been common. One method is a human naval tactic using only human power, in which a plurality of patients hold a patient and transfer it to a movable bed called a stretcher. Another method uses a simple lifting device. Specifically, the patient is wrapped in a lifting sling sheet or the like, and then transferred to a stretcher while the center of gravity is lifted from directly above. Was.

[0003]

Here, the disadvantages of the above-mentioned conventional method will be described. First, in human naval tactics using only human power, four or more caregivers are required to support all the weight of a patient. Not only is it necessary, but the posture of the transfer operation often becomes unstable, resulting in heavy muscle work, causing back pain and imposing a large physical burden on the caregiver. In addition, in this method, there is a possibility that the patient may fall down in the unlikely event that there is a concern in terms of safety. Furthermore, especially when the elderly are relocated, there is a great concern that the bones may be broken due to osteoporosis, and even a skilled person needs to be extremely careful. Next, the method using the simple lifting device not only takes time to wrap the patient with a lifting sling sheet or the like, but also requires adjustment to balance well to lift the patient in a stable posture. And had a complicated face. In addition, since the patient is lifted from directly above, there is a risk that a hanging tool such as a rope or a wire may be cut, and there is a problem in terms of safety.
Furthermore, for a bedridden patient, the unnatural and unreasonable posture caused by being wrapped in a sheet is not only cramped, but also painful, and the above-mentioned fear of fracture may not allow the use of this type of device.

[0004] Next, when the above two methods are used, both of them not only impose an unstable state on the patient in the process of transferring the patient, but also cause the patient to experience unexpected physical conditions in the unstable state. In the conventional method, the physical and mental burdens are large for both the patient and the caregiver, and there is no support for reducing the burden in the conventional method, for example, the burden or the pain may be given. In addition, the reality of medical sites such as hospitals and nursing care centers is that there are 4 to 6 beds in a small room, so the space between the beds is extremely narrow, leaving no room for large devices and machines, and the effect of solving the labor burden problem. The situation has not been given.

[0005]

SUMMARY OF THE INVENTION The present invention solves each of the above-mentioned disadvantages. A plurality of arm-type elevating devices having a parallel link mechanism are connected in parallel and on a movable base. And a split connection type support is rotatably and easily detachably attached to the tip of each arm of the elevating device, and each of the elevating devices is synchronized or independently autonomously synchronized with the operation of a caregiver as a user. Nursing caregiver by autonomously substituting the caregiver's work in accordance with the caregiver's posture by holding and lifting the caregiver from below By supporting people, caregivers can easily and safely transfer patients who are sleeping in bed.

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of the present embodiment, and 1 is a flat U-shaped base, which is an extendable auxiliary stable leg base 2.・ 2 '
And a caster with a lock at the lower part for enabling traveling. Reference numeral 3 'denotes an elevating device having a parallel link mechanism. The elevating device is fixed to the base 1 and incorporates various links, brackets, actuator control devices, etc., so that it can be powered in the elevating direction and horizontally. Can be moved manually. In the movement in the horizontal direction, in order to move lightly and quickly only by human force, it is necessary to improve the mechanical efficiency, that is, to reduce the friction loss and to reduce the weight of the movable parts such as the arms forming the link mechanism. It is necessary to reduce the inertia, and in the present invention, by using a combination of a metal and a high elasticity / high strength composite material such as titanium, aluminum, carbon or glass fiber reinforced FRP (reinforced plastic), the overall Is light and strong. Reference numeral 4.4 'denotes a split connection type support which can be easily attached to and detached from the end of the arm of the lifting device 3.3', and is made of titanium material, carbon or glass fiber reinforced FRP.
(Reinforced plastic) or honeycomb material, etc., and it has a mounting structure that allows easy replacement of differently shaped supports. Care support according to the situation of assistance is possible. Reference numeral 5.5 'denotes an operation lever, and the elevating device 3.3' moves up and down in synchronization with a command signal output by one or both of the operation levers 5.5 '. The switching mode can be switched between a synchronous mode and an independent mode in which the heights of the right and left arm tips of the lifting devices 3 and 3 'can be arbitrarily and independently adjusted. Further, reference numeral 6 denotes a folding chair for sitting, which can be installed at an arbitrary height in the center of the base 1 when in use, and can be compactly stored close to the elevating device 3 'by folding when not in use. As a result, a work area in a standing posture is ensured.

Next, FIG. 2 is a block diagram of the elevation control. Reference numeral a denotes a control unit which has an independent mode and a synchronous mode as elevation control, and any one of the modes can be selected by a changeover switch provided at a desired location. Here, first, the independent mode will be described. The command signal input from the operation levers 5 and 5 'which has a characteristic of always returning the spring to the neutral position and outputs a continuous command signal according to the operation amount is After being individually processed by the arithmetic circuits built in the control unit a, the electric power is output to the motors b and b 'as control power proportional to the operation amount by the power control circuit.
Drive. Also, c and c 'are speed detectors, which provide negative feedback of the rotation speed signals of the motors b and b' to the control unit a, respectively. The position obtained by integrating the speed control and the speed signal based on the rotation speed signal Since the position is controlled by a signal, the lifting device 3.3 ′ is independent of each arm at a speed according to the operation amount given from the operation lever 5.5 ′ via the arm mechanism d ・ d ′. And can be stopped at any position.
Next, regarding the synchronous mode, the command signals similarly input from the operation levers 5 and 5 'are averaged by addition and calculation processing by the control unit a, and the rotation speeds of the respective motors are also averaged. Since the same control signal averaged as described above is input to the motors b and b ', the arm mechanisms d and b'
Through the d ', the right and left arms of the elevating device 3, 3' are synchronously and synchronously moved up and down to the same speed and the same position. Also in this case, the speed and position holding control are performed based on the automatic control of the negative feedback of the rotation speed signals from the speed detectors c and c 'described above.

Further, the position signal is obtained by integrating the signals from the speed detectors c and c 'connected to the motors b and b' by an arithmetic circuit built in the above-mentioned control section, and is supplied to the command signal processing circuit negatively. Because the feedback is provided, even if the load on the supports 4 and 4 ′ changes and the motor shaft is rotated, a slight amount of rotation is detected and the operation lever 5.
Even if the signal from 5 'is not input, the position is always maintained, and there is no change in position due to the load.
Does not collapse. Since the position holding control which is not influenced by the load fluctuation also functions in the independent mode, the position and the speed are variably controlled by following the command signals of the operation levers 5 and 5 '. With such a control configuration, synchronous / tuning operation is possible with command signals from either operation lever, and different command signal magnitudes are simultaneously input from both operation levers depending on the care situation and posture. Is also averaged, so synchronization and synchronization can be achieved very easily, and the caregiver can safely concentrate on the care work. Furthermore, it provides a practical operation function that both hands can be used freely without restriction even in a narrow working environment.

[0009]

Next, the operation will be described from the above configuration. First, the entire support apparatus is moved and inserted between the bed where the patient is sleeping, and the lifting device 3.3 ′ is moved to the bed where the patient is sleeping. To the side of one end. In this state, the caregiver is between the U-shaped bases 1,
After securing the power of the lifting device 3, 3 ', extend the auxiliary stabilizer leg base 2, 2' and lock each caster,
Stabilize the entire board 1. Then, by manually deploying the seating folding chair 6 which is compactly stored near the side surface of the elevating device 3 ′, the seating folding chair 6 can be easily seated at the middle center position of the base 1. The caregiver can sit in a stable position to perform care work in a stable posture. Next, support 4
Is taken out of the predetermined storage position, and while slightly lifting the upper or lower body of the sleeping patient, the supporter 4 is inserted,
Put the whole body on one side from below. In addition, the support 4 'is taken out from the predetermined position, and while slightly lifting the other half of the body which is not yet supported, the support 4' is inserted so that the whole half is supported from below. Furthermore, operation lever 5
When the power switch built in the 5 'is turned on, the safety brake of the motor drive shaft of the lifting device 3, 3' and the safety position lock of each parallel link arm are released, and the independent mode is set as the lifting control. The lifting device 3
3 'can be moved up and down and horizontally moved independently.
In a state where the operation can be freely performed independently, the socket at the tip of the arm of the lifting device 3 is integrated with the connecting portion of the support 4 through the simple attaching / detaching mechanism using the operation lever 5. Similarly, the socket at the tip of the arm of the lifting / lowering device 3 'is integrated with the connecting portion of the support 4' via the simple attaching / detaching mechanism using the operating lever 5 '. As a result, the patient can be placed on the split-connection type supporters 4 and 4 'as if they were scooped and held by both arms without burdening the patient. Support 4 in this state
Use the safety belt attached to 4 'to securely fix the patient on the support 4.4'. Next, if the synchronous mode is selected as the elevation control, when an elevation signal is given from both the operation lever 5 or the operation lever 5 ′ or the operation lever 5.5 ′, the elevation device 3.3 ′ is synchronized with the support device 4.
4 'will be lifted at the same time. In this state, after pulling the bed from the bed to the horizontal stroke limit in the forward direction of the support device main body, if the power switch built in the operation lever 5.5' is turned off, the lifting device 3 The position of each parallel link arm 3 'is locked, so that it is impossible to inadvertently move the elevating device 3, 3' up and down and move horizontally. Next, while folding the folding chair 6 for sitting manually,
After storing the extended auxiliary bases 2 and 2 'in the base 1, the power cord is disconnected from the power supply. In addition, Foundation 1
By unlocking the casters at the lower part of the support device, the entire support device can be moved and moved, so that the support device can be moved out of the bed and moved to a desired place.

[0010] Next, when the patient is moved to another bed, a medical table, an operating table, a stretcher or the like after moving to a desired place, the transfer can be performed in the reverse order of the above-described operation. In addition, as the elevating control, switching to the independent mode and the synchronous mode can be performed at any time, and either mode is selected according to the situation, and the posture of the patient is adjusted by appropriately using the desired shape of the support. You can change it freely. The nursing care support device uses a commercial AC 100V power supply to reduce the overall weight of the device. However, the motor must be changed to a DC motor type, and a battery and a charger must be mounted together. Thus, it is needless to say that it is not necessary to plug and unplug the power cord each time the device is used. In this case, if a permanent station having a power supply port for charging a battery is provided at one corner of a corridor of a hospital or the like, a system that further improves convenience can be constructed.

[0011]

[Effects] Next, the effects will be described from the above configuration and function. When a patient sleeping on a bed is moved, not only four or more caregivers are required in the conventional method, but also patients and caregivers. For both of the above, physical and mental burdens, pains and dangers were involved, but by utilizing the nursing support device of the present invention,
It is possible to transfer patients who are sleeping in bed safely and safely, and for both patients and caregivers,
Not only does it not impose any physical or mental burden, but it is especially safe for patients because they can be held up with both hands from below, compared to situations close to handling luggage, such as when being lifted with conventional simple devices. It has a strong feeling and is held at the caregiver's chest, enabling face-to-face dialogue, increasing mental security and trust, and providing the basics of nursing care at the geriatric care setting. And there is an extremely large effect of supporting care that emphasizes mental dignity. Further, the present invention is not only for nursing care support for bedridden elderly people, but also as an application example, for example, when transferring from an operating table to a stretcher of a patient under anesthesia after surgery in an operating room, transferring an encephalopathic patient, dementia patients Even when the patient is unconscious, such as in the care work, there is a great effect that the caregiver can safely work alone, and an effective problem solving means is provided.
