Lifting and transport device for sick people
The invention relates to a lifting and transport device for sick or disabled people with a carrying device adjustably attached to a base part.

Due to the increasing shortage of staff, particularly in hospitals and homes for the elderly and disabled, it is becoming increasingly important to make the work of care staff easier. For example, to lift patients, e.g. to make the bed, to transfer them to a stretcher or vice versa to transfer them from a stretcher to a bed, at least two people are generally required if the patient cannot move or help themselves.

Simple lifting devices are already known, which can be used to place bedridden patients in a bathtub, for example. However, the known stretchers are relatively uncomfortable to use and not transportable. Furthermore, a second person is often still necessary to provide adequate care for the patient.

The present invention is therefore based on the object of providing a lifting and transport device for sick

and disabled people that are very universally

Si can be used, whereby to care for the sick or

&eeacgr; In case of need only one person is required

is, in particular, while at the same time a trans-

&psgr; port possibility is given.

■;> According to the invention, this object is achieved in that

the base part is movable, that a crane arm protrudes freely from the base part, which can be adjusted in height and pivoted around a vertical axis, and that the tra-

j g device pivotable about a vertical« axis on the

·

-3- front end of the crane arm.

The lifting and transport device according to the invention can be used very universally, and only one person is required to operate it if necessary. The patient can not only be lifted up using the carrying device, but can also be moved sideways using the crane. If the mobility of the base part is also used, the lifted patient can even be transported over longer distances.

In a very advantageous development of the invention it is provided that the crane arm and the support device are adjustable and movable by hydraulic devices.

By using a hydraulic unit in conjunction with an electrical and/or electronic control system via a battery or accumulator as an energy source, the device according to the invention is independent of an external energy supply, which means that it can be used very universally. If necessary, it is only necessary to provide a battery or accumulator for the electrically or electronically operated parts or other electrical accessories .

which can be easily recharged when the device is not in use. In general, the battery or accumulator will be placed in the base part.

If, in a further development according to the invention, it is provided that the base part can be moved by a motor drive, the work for the care person is made even easier, because in this way the transport can take place automatically.

In order to make cornering possible in a simple manner, provision can be made for a drive device to be provided for each of the two opposing wheels of the base part, which can be controlled independently of one another.

By controlling the drive devices differently, the movable base part can move around curves.

A friction wheel drive can be provided for torque transmission, since/3 a friction wheel drive is arranged in the base part for this purpose. Of course, other drive and control options are also conceivable within the scope of the invention.

To stabilize and secure the position of the base part during the lifting process of the patient and any possible swiveling by the crane arm, the base part can be provided with extendable or extendible hydraulic supports.

Of course, mechanically or electrically operated supports can also be provided within the scope of the invention.

A simple connection and pivoting of the crane arm with the base part is provided if the crane arm is attached in an articulated manner to a plate which can be rotated about a vertical axis and is arranged on the base part.

In general, a single-armed, freely projecting crane arm will be sufficient. In order to ensure that the necessary height adjustment is possible in addition to the ability to pivot around a vertical axis, a hydraulic cylinder can be attached to the plate in an articulated manner next to the crane arm, while the front end of the piston of the hydraulic cylinder engages the crane arm.

By extending and retracting the piston accordingly, the crane arm can be adjusted in height by changing its inclination relative to the vertical axis if it is attached to the plate in an articulated manner with an axis inclined to the vertical.

In a further development of the invention,

ria/3 the crane arm has a front, horizontally

■ has an angled lifting arm on which a par-

v allel to the lifting arm running hydraulic cylinder

>$ is arranged, on whose piston a suspension

direction for the carrying device.

The hydraulic cylinder with its piston also allows horizontal compensating movements to be carried out on this

precise positioning of the Traq device is possible.

By means of a rotating member that is connected to the suspension device so that it can rotate about a vertical axis or forms a part of it, the support device can also be positioned precisely in relation to the patient to be lifted.

A simple design of the carrying device can be:. that it has two gripping arms, which

-7-

each provided with: rails, from the lower ends of which support parts with at least approximately horizontal axes protrude inwards.

By operating the two gripping arms together, the carrying device can be opened and closed easily, allowing the person to be lifted to be grasped in a similar way to the kinematics of an excavator with two side scoops.

In a further development of the invention, it can be provided that the rails on each side are arranged on a common horizontal tracer, to which a hydraulic adjustment device for an opening and closing movement of the two gripping arms acts.

The two side supports create a central unit to which the hydraulic adjustment device can be attached. At the same time, rails can be arranged on the support in a desired order and at a desired distance depending on the application.

It is advantageous if the rails are connected to the carrier in an adjustable manner on a horizontal axis .

that are.

In this way, the rails can be optimally adapted to the person being lifted, as this allows for side bending and the support parts of the rails can be positioned, for example, on the shoulder, under the buttocks and, for example, on the neck, depending on the patient .

It is also advantageous if the rails are adjustable in length.

The length adjustability further improves the ability to adapt to the patient.

A simple possibility for length adjustment can be that the rails are made of two parts with an upper part that is hingedly attached to the carrier and a lower part from which the support parts branch off.

In a further development of the invention, it can be provided that the hydraulic adjustment device is detachably connected to the supports.

&igr; ill « · · J

Due to the detachability between the hydraulic adjustment device and the supports, the entire support device can also be replaced if necessary.

For example, it is possible to provide angled supports instead of horizontal supports, with adjustable rails attached to each leg of the angle parts.

Using a carrying device designed for this purpose , patients can be lifted and transported in a sitting or semi-sitting position, which is more comfortable for them, provided that their state of health or disability allows this type of transport.

In general, four rails per support arranged at a distance from each other on each side will be sufficient. If necessary, more rails are of course possible, whereby the support parts of the rails can be padded to prevent pressure points or even injuries to the patient.

An embodiment of the invention is described in principle below with reference to the drawing.

The lifting and transport device for sick or physically handicapped people, including patients with accident injuries, has a base part 1, which essentially represents a mobile housing, which is provided with two larger driven wheels 2 and one or two smaller front guide wheels 3 that can rotate about a vertical axis. The two

-11-

The rear wheels 2 can each be driven independently of one another '*' by a motor 4 via a V-belt and a V-belt pulley 6 connected to the wheel 2.

On the top of the base part 1 there is a rotating plate 7 which can be rotated about a vertical axis by a motor, e.g. via a hydraulic drive. One end of a crane arm 9 is pivotably attached to the rotating plate 7 via a joint 8. At a distance from this, a hydraulic piston 11 is also attached to the rotating plate 7 via a further joint 10. The end of the associated hydraulic piston 12 protruding from the top of the hydraulic cylinder 11 is supported on a bracket 13 of the crane arm 9. Above the bracket 13, the crane arm 9 is provided with a lifting part 14 angled in the horizontal direction. A further hydraulic cylinder 15 is arranged on the angled lifting part 14 of the crane arm 9, the hydraulic piston 16 of which protrudes to the front. Depending on the position of the crane arm 9, which generally extends upwards at an angle from the turntable 7, the angled lifting part 14 of the crane arm 9 and thus also the hydraulic piston 16 will extend at least approximately in a horizontal direction. In principle, however, the crane arm 9 can be moved in the direction of the arrow around the joint 8 in accordance with the displacement possibility of the hydraulic

-12-

piston 12 can be pivoted in the direction of the arrow. In this way, a support device 17, which is connected via a suspension device 18 to the front end of the hydraulic piston 16 and via a push rod 19 to the angled lifting part 14 of the crane arm 9, can be positioned horizontally and vertically.

The suspension device 18 is provided with a rotary member 20 that can be rotated about a vertical axis and can be rotated hydraulically, for example. A support 22 is connected to the rotary member 20 at each side via a rod 21. On the two supports 22, which extend in the horizontal direction in their basic position, four rails 23 are arranged next to each other and at a distance from each other, each of which is articulated at one end via a pivot point 31. However, the articulated connection can also be fixed in a desired position if required by a clamping device (not shown). Clamping screws, for example, can be used for this purpose. The rails 23 are each made of two parts, namely they each consist of an upper part 23 and a lower part 230 connected to it in a length-adjustable manner. The length can be adjusted, for example, by means of an elongated hole 24, which is arranged, for example, in the upper part of the rail 23 and has a threaded pin 25,

&bull;&bull;&bull;«&bull;■t ■· »r

which is fastened in the lower part 230 of the rail 23 and is clamped by a clamping screw after a correct positioning in the slot 24. In this way, the total length of each rail 23 can be adjusted, individually for each rail.

Horizontal support parts 26 extend inwards from the lower parts 230 of the rails 23, which are formed in a simple manner by a corresponding deflection of the lower parts 230 of the rails and are thus integral with the rails. Each rail 26 can be provided with a support cushion 27 if required.

In the embodiment of the support device 17 shown in Fig. 3, the two supports 22 run linearly and in the basic position in a horizontal direction, whereby with a corresponding length of the rails 23, the resulting support surface for a person to be lifted and transported on the support parts 26 also runs essentially horizontally.

In Fig. 4, an embodiment of a support device 17 is shown, which is designed for a sitting or

&bull; · · · ■ I III · ·t * t

&Ggr;:

semi-sitting position of a person to be lifted. Basically, however, the support device is constructed in the same way as the support device according to Fig. 3. The only significant difference is that the support 22A is now angled against the horizontal direction. With a corresponding arrangement of the rails 23 essentially vertical to the longitudinal direction of the two parts of the support 22A, this also results in a support surface for the person to be lifted that is bent upwards compared to the horizontal and thus a sitting or semi-sitting lifting and transport position.

In general ^, four rails spaced apart from each other will be sufficient, with the two inner rails being used as a support surface for the neck and knee ^area and the two inner rails for the buttocks area of the person to be lifted.

To facilitate operation and mainly so that the lifting and transport device can be operated by a caregiver alone, it is provided with a remote storage device 28, which is arranged, for example, in the base part 1. Such

Remote control devices with a receiver and a control part are generally known, which is why they are not described below. The remote control can be via radio, infrared, ultrasound or similar. Of course, the base part can 1 but also with a corresponding control panel for |

The base part 1 is controlled by a corresponding control y

The lifting device 17 is moved as close as possible to the desired location, e.g. a bed with a person lying in it, by means of the two drive motors 4. The hydraulic supports 29 are then extended so that the base part 1 is positioned and secured. By pivoting the crane arm 9 accordingly, further horizontal and vertical adjustments of the support device 17 are possible. In addition, a final fine adjustment can also be made by adjusting the hydraulic piston 16 accordingly. The rotating member 20 can be used to position the support device 17 with the two supports 22 above or to the side of the person to be lifted in such a way that the supports 22 run parallel to the longitudinal direction of the person lying down.

-16-

The adjustment device with the rod 21 is then operated in such a way that the horizontal support parts 26 are brought so close to each other that they support the person to be lifted. The mode of operation of the rod 21 corresponds, for example, to the mode of operation of an excavator , which is generally known, and is therefore not discussed in more detail below.

The person grasped by the support device 17 can then be lifted by a corresponding lifting movement of the crane arm 9 by extending the hydraulic piston 12. By operating the turntable 7, the lifted person can then be swiveled as desired in the horizontal direction, whereby by operating the rotary member 20, changes in position with respect to the longitudinal direction of the person are also possible, for example in order to lay them correctly on another bed that is at an angle to the first bed. By moving the hydraulic piston 12 in the opposite direction, i.e. by moving it into the hydraulic cylinder 11, the person can then be laid down in the desired place. The support device 17 is then opened again by moving the support parts 26 apart.

If the lifted person is to be transported further, e.g. to an operating theatre or another room, this is also possible with the lifting and transport device. To do this , it is only necessary to retract the hydraulic supports 29 and to activate the drive motors 1 for the wheels 2, whereby the entire unit can be moved with the person lying in the support device 17.

The devices required for the hydraulic actuators, such as a hydraulic pump, can be arranged in the base part 1, with hydraulic lines running inside the crane arm 9 and its angled lifting part 14 serving to supply energy to the hydraulic piston 16 of the rotary member 18 and the adjustment device 21. For the electrical or electronic control and activation of the driven parts, a battery or accumulator 39 can be arranged in the base part 1 to supply energy.

In order to be able to replace the support device 17 if necessary, e.g. to exchange between the embodiment according to Fig. 3 or Fig. 4.
