The present invention relates to the field of supporting arrangements, devices or systems for the rehabilitation and treatment of patients or animals suffering from motor disabilities resulting from surgery, chronic disorders, accidents and the like. Preferably, the present invention refers to aerial or overhead supporting arrangements, devices or systems that allow the patient or animal under treatment to remain suspended.
The state of the art concerning devices that are helpful for human patients suffering from motor disabilities basically comprises two well-distinguished family of products: certain cranes that allow patients to be lifted and transferred to a different place, such as on a bed or wheelchair, and from a wheelchair into a bathtub or on a therapy table.
In effect, U.S. Pat. No. 3,780,663A refers to an ambulatory system for use by debilitated ambulatory patients and the like. The system consists of a track network including a primary track, which extends the length of communicating corridors, and a plurality of secondary tracks, each extending from a point in close proximity with the primary track, and terminating at a point remote therefrom, and a travelling truck, supported by the track network, having a harness depending therefrom for substantially supporting the weight of a human body in suspension for assisting the patients in walking along the corridors as well as to enter and depart from various areas through which the secondary tracks are extended.
This system allows only a forward-and-backward unidirectional track along the rails where the same are installed. This system is not viable for travelling along the x-y plane in any direction within a particular area, such as a recovery room. The arrangement cannot be regulated as desired when used with the applied load. The harness is provided for human patients but not for animals under recovery treatment. Therefore, it is desirable to have a device allowing both ambulatory human and animal patients to be ad lib transported within a given area with controlled load and without any track restrictions. The harness and the supporting bar comprising four lifting points with two front lifting points spaced from two rear lifting points, provide greater support to the back of the patient and facilitate the entry and removal of the patient. A solid state motor control allows easy control of the speed of the motor for the patient lift system. In other features, the motor control incorporates a remote control which provides a safer use of the device. The sling or harness may also comprise a support for the patient's head.
U.S. Pat. No. 6,315,138 B1 refers to an overhead support system. A riding surface is located over a space and supports at least one overhead cart from which a load is supported by a tension element. A plurality of spherical elements is positioned between the riding surface and overhead cart and is attached to either the cart or the riding surface. The load can be moved horizontally in the space by applying a horizontal force to the load causing the cart to move over the riding surface while carrying the load in the horizontal direction. In preferred embodiments, the riding surface is an array of spoked rimless wheels. In other preferred embodiments the riding surface is a slot track, or a combination thereof. In other preferred embodiments a hoist assembly is used to raise and lower the load, which may be located below or above the riding surface. In preferred embodiments casters are mounted on the top of the riding surface to permit easy horizontal movement of the cart over the casters. In other preferred embodiments the riding surface is flat and casters are mounted on the bottom of the overhead cart and above the patient's head.
Patent Application GB 1092926 refers to a hoisting device for invalids and the disabled which comprises a casing that houses an electric-motor driven shaft to raise and lower a cable wound on the shaft, the remote end of the cable being attached to an invalid harness. The motor which drives the shaft through reduction gearing is operable forward or reverse either by cords coupled to switches in the casing, or by a switch box held by the invalid. A motor switch on the casing is operated by the top of the harness in the case of overwind. The casing is pivotally connected to a wheeled table running in rails. The table is moved along the rails either manually or by motor driven endless cable. In a further embodiment the hoisting motor is controlled by a suck-blow switch valve operated from the invalid's mouth.
Document DE 3432045 A1 refers to an overhead transporting device comprising a frame that can be moved along a rail or track. This frame is suspended from the track by two wheel systems and is driven by a friction roller. The weight of the frame and its accessories and the weight of the load that can be suspended from a transporting harness cause the frame to turn on the wheels near the friction roller because the friction roller is pressed against the track based on the load. The friction roller is driven by an electric motor fed by an electric motor installed on the frame.
On the other hand, there are standers which, based on a totally different operation principle, allow human patients to stand on their two legs when the patient is placed on a fixed platform, by securing the patient with belts and other fixing or attaching means. However, these standers or standing devices do not allow them to walk, either alone or with assistance.

In order to find a solution to the technical problems above described, the present invention comprises a standing device (1) for the treatment and/or rehabilitation of patients (2) who are in need thereof, and which device comprises two fixed parallel rails (3) on which two movable parallel rails (4) can freely move on wheels (5) in a forward-backward direction (axis y) and are perpendicularly disposed with respect to the former. On the assembly of movable parallel rails (4) a base structure (7) is movably and freely linked thereto by wheels in a right-left direction (axis x) (8), which base structure comprises an electric motor which allows, by a remote control (13), lifting or lowering a wire (10) along a controlled upward-downward movement (axis z), with several kinds of harnesses (12) coupled on the end thereof, depending on the physical and medical features of the human or animal patient (2) under treatment.
The motor (6) is mounted on the movable base structure (7) with wheels (8) allowing transmission of the left-right movement (axis x) to the motor assembly (6), wire (10), hook (20), eventually an intermediate hanger (21), harness (12) and human or animal patient (2) under treatment along the movable parallel rails (4).
By harness (12) is meant any device allowing the patient to be lifted or suspended by action of the motor (6) of the standing device (1). Such harnesses may be of several kinds, either fastened to the body or involving suspension or support, depending on the rehabilitation procedures to be followed.
Thus, the human or animal patient (2) under treatment can move freely, with our without assistance by a third party, in any of the above mentioned three directions: forward-backward (axis y) and right-left (axis x), in plane (x, y), which is done by the patient himself/itself while moving by his/its own means, and upward-downward (axis z), in which case a motor (6) is employed to implement said movement, either by the patient himself or by an assistant third party. A dynamometer (11) sequentially disposed between the motor (6) and the human or animal patient (2) under treatment allows measuring of the load applied thereon at any time.
It is therefore an object of the present invention to provide a standing device (1) which facilitates the combined movement in the three optional dimensions, thereby allowing a free left-to-right or vice versa movement and a forward-to-backward or vice versa movement, and the controlled upward-to-downward movement, by human or animal patients (2) with motor disabilities resulting from neurological, orthopedic or rheumatic disorders, and which device is intended for their treatment or rehabilitation comprises the following elements:
a pair of fixed parallel rails (3);
a pair of movable parallel rails (4) mounted by wheels (5) on the fixed parallel rails (3); and
an electric motor (6) mounted on a movable base structure (7) supported by wheels (8) on the movable parallel rails (4) and which shaft (9) is linked to a wire (10) from which a dynamometer (11) and harness (12) are suspended, the electric motor (6) being operated by remote control (13).
Pursuant to a preferred embodiment, the standing device of the present invention consists in the above mentioned elements, as follows: the two fixed rails (3) are parallel installed at both ends or corners of a room where the device (1) is to be installed, in a direction coinciding with the “forward-backward” direction of walking. These rails (3) are grooved so that they allow a group of several wheels (5) of the movable parallel rails (4) to move within the grooves or canals (14) throughout their length.
Preferably, the fixed parallel rails (3) are installed in the room by a plurality of perpendicular mounting parts (15) that link the ceiling to said rails (3).
On the other hand, the two movable rails (4) are parallel mounted, linked by at least two rigid metal pieces (16) to secure such parallel condition, which are preferably mounted to the ends of said movable rails (4).
Preferably, said rigid metal pieces (16) comprise a beam (17) joined to two couplings (18) at the ends thereof, which are fixed to the ends of each of the movable rails (4), an assembly of movable rails (4) and both rigid pieces (16) thereby forming substantially a rectangle. The movable rails (4) are linked to the rigid pieces (16) by mounting means known in the art, such as couplings and welding, couplings and screws, couplings and pins, etc.
These movable rails (4) are also grooved so as to allow several wheel assemblies (8) to move within the grooves or channels (19) throughout its length. These movable rails (4) are disposed so that they intercept fixed rails (3) at a 90° angle.
On both ends of each of the movable rails (4) there is a plurality of wheels (5) installed. These wheels are in charge of providing movement to the movable rails (4) along the entire track allowed by the fixed parallel rails (3). Preferably, the wheel assemblies (5) are fixed on ends of the rigid pieces (16) which keep the movable rails (4) in a parallel condition.
Likewise, other wheel assemblies (8) are installed on the ends of the base structure (19) of the electric motor (6) to allow the movement thereof along the grooves or channels (19) of the movable rails (4), thereby allowing “left-to-right” displacement.
In a preferred form of embodiment, the base structure (19) of the electric motor (6) consists in a painted plate structure having substantially the shape of a casing. This structure (19) is mounted below the movable parallel rails (4) and linked thereto by wheel assemblies (8) that allow the movement of the assembly formed by the base structure (19) of the motor, the electric motor (6), remote control (13) of the motor (6), wire (10) with a hook (20) on its end, eventual intermediate hanger (21) for fastening, harness (12) and human or animal patient (2) in a “left-to-right” direction. Preferably, the wire (10) is a wire (10) made of steel or the like.
The combined movement in a “forward-backward” direction and in a “left-to-right” direction allows the user or patient (2) of the standing device (1) to walk along the floor surface or plane (22) of the room where the device (1) has been mounted, in any direction he may choose. That means that the user or patient (2), either human or animal, can walk along the room (19) where the standing device (1) has been mounted in any desired direction, without any restriction as to a predetermined direction by reason of the geometry of the device itself (1), except for the maximum limits imposed by the size of the device (1) resulting from the size of the pair of fixed parallel rails (3) and/or the size of the room that finally determines the previously referred sizes.
Thus, the human or animal user or patient (2) can walk along the room in a transversal forth and back direction, in a clockwise or counter-clockwise round direction, in zig-zag, depending on the perimeter of the location (19), longitudinal or transversal forth and back direction, or any combination of the above, as desired, with a load on the legs or lower limbs determined by the hoisting applied by the electric motor (6).
The electric motor (6) with its power supply (6′) is mounted within the casing that constitutes the base structure (7) of the electric motor (6). This electric motor (6) is operated by a remote control (13), which controls the upward and downward movement of a wire, (10) preferably a steel wire or cable (10), to which a hanger (1) is attached by a hooker (20) from which a harness (12) is suspended, or a harness is directly suspended therefrom without an intermediate hanger (21). Preferably, a dynamometer (11) is placed between the wire (10) and the hanger (21) or harness (12).
Similarly, the remote control (13) can be a remote control which provides a more safe operation by facilitating the remote control of the device (1) by the human patient (2) himself or any person assisting the patient (2), either human or animal.
The speed of the shaft (9) of the electric motor (6) can be controlled by a mechanical speed reducer (23) or by an electronic reducer, or any combination thereof. Preferably, the motor (6) is fed by a single-phase voltage of 110 Volt or 220 Volt, but the remote control (13) has an applied voltage of 12 Volt achieved by reducing the line voltage of 110 Volt or 220 Volt applied to the motor (6).
The end of the shaft (9) of the motor (6) or mechanical speed reducer (23) comprises a pulley (24) through which a wire (10) is passed, preferably a steel wire, by which the load harness (12)/patient (2) load borne by the device is hoisted or lowered. The end of the wire (10) is attached and the pulley (24) winds and unwinds the wire (10) during the upward and downward movements of the load.
The wire (10) transmits the force exerted by the motor (6) to the individual or patient (2) fastened to the device (1) by the harness (12), which is selected as required depending on the medical or veterinary disorder to be treated. Thus, an “upward-downward” movement is achieved.
The dynamometer (11), that is sequentially installed between the hook (20) of the wire (10) and the coupling of the hanger (21) or directly the harness (12), allows measuring the weight of the patient (2), either human or animal, and, in turn, to distribute the weight supported by the limbs during the treatment or rehabilitation therapy. This weight measuring mechanism allows working with a full control of the load applied to the human or animal patient (2). Preferably, the dynamometer (11) is a digital dynamometer (11) which, even more preferably, comprises a memory that stores the patient data for each session, or, either, a transmitter that sends said data to a terminal where the data is stored.
The several harness models (12) herein suggested overcome several situations and needs of human or animal patients (2), such as: moving from and to a wheelchair, passing from a table to a surgery table, walking and standing exercises, physiotherapy in swimming-pools or the like, vestibulation exercises, progressive recovery by equines in boxes, recovery by pets such as cats and dogs, treatment of animals intended for cattle raising such as stallions and milk high-yielding cows, treatment and rehabilitation of zoo animals, etc.
The harness (12) for treatment and rehabilitation of a human patient (2) can be selected from: harness (12a) for standing device, which fastens the legs by the groin and also fastens the trunk in order to keep the patient in an upright position (
The standing device harness (12a) with leg fasteners by the groin and trunk fasteners for keeping the patient in an upright position (

Preferably, the above harnesses (12) for use with patients of more than about 90 kg by weight are made of hypoallergenic vinyl canvas and the lines are preferably made of nylon fabric or the like.
Therapy tables used for patients with burns are preferably made of hypoallergenic vinyl canvas and hydrating or moisturizing gel, which replaces the plasma, as this material can be sterilized by moist heat.
In the veterinary field, a harness (12n) for quadruplet animals is provided, preferable for equines, which bears the weight of the animal (2) and distributes such weight among several supporting points. In a preferred form of embodiment, the harness for equines (12n) comprises several portions: a ventral supporting assembly 107, which is substantially rectangular and is formed by a plurality of layers of different types and materials, between said layers there being at least two independent inflatable receptacles (108) with multiple cavities (109) mutually linked to two interconnecting conduits (110) extending longitudinally, where said cavities (109) are transversally and parallel disposed in an alternate pattern covering the entire surface of the supporting assembly (107).
Preferably, the plurality of layers of the vental supporting assembly (107) comprise, from the inner to the outer layer: a first fabric layer (111), basically made of a canvas-type cotton or Denim (jean), which is in contact with the skin of the animal; a second layer (112) made of felt, preferably of wool fibers; a third layer (113) formed by a polyurethane rubber foam; a fourth layer (114) formed by at least two independent inflatable receptacles (108) with multiple mutually related cavities (109), said receptacle being made of a gas-proof fabric or film; a fifth layer (115) formed by polyurethane foam rubber; a sixth layer (116) formed by felt, preferable made of wool fibers; a seventh layer (117) basically made of cotton fabric, of a canvas or denim/jean kind; and an eighth layer (118) formed by a wound fabric with alternate intercrossed lines (119) where a plurality of lines (120) project laterally, which end in the supporting rings (121), said lines (119, 120) being preferably of a nylon or like fabric. The different layers (111, 112, 113, 114, 115, 116, 117, 118) are sewed one to the other as a whole assembly.
The plurality of side lines (120) that end in corresponding supporting rings (121) of said ventral supporting assembly (107) are useful in fixing the harness (12n) to the supporting points of a hanger or supporting frame or structure (122).
Likewise, and additionally, the harness (12n) comprises four substantially conical sleeves (123) for holding the forearms and highs of the equine (2), each crossing at least two lines (124) that end in corresponding supporting rings (125), which are sewed for fixing the sleeves (123) to the supporting frame (122).
Preferably, the sleeves (123) are made of rubber fabric and polyurethane, where this latter material provides an efficient cushion pattern for the animal while in use. On the other hand, lines (124) are made of nylon fabric.
The supporting frame (122) is formed by a series of bearings (126) and beams (127) that constitute the corners and vertexes of a regular prism with substantially rectangular base and sides and which front and back faces are substantially triangular, where longitudinal bearings (126) comprise a plurality of supporting grommets (128) for attaching the supporting rings (121125) to the ventral supporting assembly (107) and sleeves (123), and, above, at least one supporting grommet (129) for hanging the assembly from a supporting hook (20) linked to the lifting motor (7) by a wire (10) pulley (24).
The multiple cavities (109) of the inflatable receptacles (108) are filled with compressed air by at least one compressor (130), where air may be filled in an independent and alternate manner by valves (131) that allow the entrance and exit of air in a predetermined manner, thereby increasing or reducing the pressure of each inflatable receptacle (108) to achieve an alternate and efficient massage on the belly and sides of the animal patient (2).
Preferably, the compressor (130) has a compressing capacity of 75 to 110 pounds/square inch and compresses air continuously on the valves (131) which alternatively release a pressure of about 14/pounds/square inch every 3 to 5 or 10 minutes. Each valve (131) prevents the air release and allows the air inlet to recover the pressure by starting a new cycle. Thus, when one of the inflatable receptacles (108) is inflated, the other is decompressed and vice versa on a continuous pattern and provides the animal (2) with a massage on its ventral area.
Also preferably, the inflatable receptacles (108) are made of a resistant and air-retaining material selected from waterproof nylon fabric and a polyvinyl film, such as Panaflex or the like.
Whenever necessary or useful, a dynamometer (11) is installed between the hook (10) at the end of the wire (10) of the standing device (1) and the harness (12) in order to control the weight borne by the limbs of the human or animal patient (2).
Once the human patient has been provided with the harness suitable to his/her physical condition, the harness is then attached to the end of the preferably steel wire of an intermediate hanger
Then, the whole assembly together with the human or animal patient makes up a single unit, which is ready to start with the rehabilitation exercises.
The operator assisting the human or animal patient operates the remote control so that the human or animal patient can be lifted and transported with no effort to the point of the room where the activity is to be performed.
As the case may be, the operator will apply a particular load on the limbs of the human or animal patient by a simple process which comprises softly and slowly releasing the wire, centimeter by centimeter, until the dynamometer indicates that the desired load has been reached. For example, if the human or animal patient weighs 70 kg, when the dynamometer indicates 50 kg, the patient will be bearing a load of 20 kg on his legs.
At any time, the human or animal patient will be able to move by his/its own means if possible on account of his/its condition, or by the assistance of the operator, without falling or stumbling, since the harness is firmly secured to the whole structure.
When human or animal patients under rehabilitation move between two points within the area covered by the device, namely, from one end to the other of the fixed parallel rails and from one end to the other of the possible track of the movable parallel rails, the device will work as a suspended movable standing device.
However, this device mainly allows diverse and highly valuable applications for accelerating the rehabilitation process in human or animal patients, and such applications are not limited to those intended for lifting or laying human or animal patients or facilitating limb rehabilitation with a controlled load.
The kind of human or animal patients particularly benefited from this invention are those affected by lower-limbs motor disorders caused by neurological, orthopedic or rheumatic conditions.
The neurological disorders treated with this device comprise all those resulting in difficulties to make translational movements, either by the patient himself or by caretakers, or to stand, as in the case of paraplegia or paraparesis.
Orthopedic disorders comprise those exhibited by human or animal patients who have suffered any kind of traumatism temporarily preventing their motor activities. In this case, it is helpful for them to perform rehabilitation activities within or outside other spaces of common assistance, as in the case of parallel bars.
According to this present invention, the human or animal patient exceeds the restricted scope of activities defined by parallel bars. In fact, they are not necessary at all, since the suspension standing device allows the human or animal patient to move in different directions without the support of the bars.
Using the digital dynamometer will allow the performance of exercises on lower limbs, exercises involving weight transfer and positional exercises, without any excessive partial and progressive load as necessary, since said load can be then determined precisely.
Likewise, and according to this invention, rehabilitation processes are shorter in time, since the previous strengthening of upper limbs for parallel bars or crutches will be no longer necessary.
The human or animal patient under rehabilitation will be also able to perform exercises in a vertical position well before and more effectively than in a quasivertical position, this latter position being usually the only one applying partial load on limbs in the absence of an invention like the one herein described.
This device ensures that the human or animal patient under treatment will not fall down at any moment while performing the rehabilitation/recovery activities, thereby allowing an otherwise impossible standing position, i.e., allowing an individual to exercise without the continuous and constant assistance by third persons.
It is important to note that the controlled-suspension standing device according to the present invention allows neurological human and animal patients to enjoy a full and natural vertical and standing position as compared with any other prior device. This is mainly achieved because the standing device of the present invention is of a “suspended” kind.
This present invention provides a fully innovating and overcoming solution for kinesiology treatments aimed at the rehabilitation of humans or animals with difficulties or complete inabilities to walk and/or stand, and the inventive device can be used both on hard surfaces and in swimming-pools, it being also possible to precisely control the working load applied on the lower limbs of the human or animal patient under treatment.
Likewise, the different vestibulation harnesses and the vestibulator cone are precisely used for vestibulation exercises. By these exercises the patient is intended to recover the balance lost as a result of any inner ear disorder caused by a viral infection, cranial traumatism or Menière disease.
Since the inner ear is responsible for the sense of balance and positioning in space, when the same is affected by any disorder the symptoms normally appearing as a result include dizziness, nausea, vomiting and instability. This disorder can be treated by means of specific exercises until a total recovery is achieved. In fact, the device of the present invention provides the treatment for this disorder.
Within a strictly veterinary field, any animal suffering from post-traumatic or post-surgical recovery processes which require to keep the animal standing and controlled, or which require any assistance while standing, can be supplied with a harness ad hoc and suspended from the device according to the present invention until the animal is fully recovered, while calibrating the load exerted on the animal limbs.
For example, the use of this inventive device on equines is to be noted, since the device operates in a manner similar to that used on humans and not only allows keeping the animal in an upright position but also enables the animal to move in any direction within the surface covered by the apparatus.
The invention can be used for recovery after anesthesia, surgery—when surgery is conducted on one side-, short or long-term care of horses or any other quadruplet animal with difficulties for standing or which must bear reduced weight on their limbs, as well as in the case of horses or any other quadruplet animal with neurological problems, among the most outstanding cases.
This kind of support, apart from being more comfortable and safer, dramatically reduces the risk of injuries and violent reactions derived from handling of the animal. On the other hand, as this device allows transportation of the animal, the recovery process is thus facilitated because the animal does not need to remain in a resting position when affected by injuries on its limbs or by any other disease that may prevent it from moving to drink and eat.
When horses and any other quadruplet animal remain in a lying position for a long time, they suffer severe health complications, such as lung congestion, micitis and scars, which in some cases may lead to death of the animal. For that reason, a device that enables said animals to remain standing and to walk, when they will be otherwise lying, proves to be highly useful.
Typical uses of the device include those for horses with neurological disorders or with any of their limbs broken, which require limiting the weigh load to be borne by said limbs during the recovery process. The animal can then remain standby until, while recovering, the weight to be borne by its limbs is regulated and the animal manages to move in any direction within the room or place of location.
For the case of fractures or any kind of limb problems, the animal normally reacts by passing part of its weight to the healthy limbs, which are then required to make an excessive effort that will subsequently lead to an even greater problem.
Another relevant use of this invention comprises ensuring the flotation of the horse or any other quadruplet animal in a swimming pool. Horses may be frequently drown while training in swimming-pools, because, once they start to sink, it is practically impossible to make them float.
The device according to this present invention significantly improves the quality of life of these animals by relieving them from the pain produced by their own weight on the affected body portions but, in addition, it enables them to move on the floor plane and to thereby walk while bearing little weight, which is helpful during the rehabilitation process.
The main advantage of the inventive standing device as compared with prior art devices is that it comprises a “suspended” device, i.e., the human or animal patient can be hung or suspended from an supporting means placed overhead, which allows the free and full movement of all lower limbs of the patient.
The foregoing discloses the high versatility of the device of the present invention which is not found in any other prior art device.
