Description

LUMBAR TRACTION APPARATUS

FIELD The present invention relates to a lumbar traction apparatus.

BACKGROUND One way to relieve back pain is to apply spinal traction, that is decom- pression therapy relieving pressure on the spine. Such treatment can be performed manually or mechanically.

The known ways to perform lumbar traction treatment are, however, dif- ficult and cumbersome to apply in practise. There is thus a need for a device that is easy to use and adapt to suit the subject person.

SUMMARY The object of the invention is to provide an improved lumbar traction apparatus.

The object is achieved with an invention defined in the independent claim. Some advantageous embodiments have been disclosed in the dependent claims.

DRAWINGS The invention and some advantageous embodiments have been illus- trated in the accompanying drawings, where Figure 1 shows an embodiment of a lumbar traction arrangement ac- cording to the invention; Figure 2 shows a side elevation of Figure 1; o Figure 3 shows the top elevation of Figure 1; and S Figure 4 shows the bottom elevation of Figure 1.

? DESCRIPTION OF SOME EMBODIMENTS N The embodiments relate to an arrangement or apparatus for enabling s vertical traction to a person's lumbar.

0 In the embodiments, there is provided an apparatus, where a sitting © person/user/patient is arranged to move in at least substantially horizontally, and N the device is arranged to cause variable traction to the person's lumbar during the N horizontal movement. In some embodiments, the variable traction refers to linearly changing traction. That is, the traction induced on the person, may increase linearly when the person moves from one end to the second end in the device. Respec- tively, when the person returns from the second end of the device to the first end, the traction may decrease linearly. This provides the significant advantage that the traction force is easily controllable by the person and therefore the device is safe to use.

In the embodiments, the person is arranged to sit when using the de- vice. Thereby the person's back or spine is in vertical direction, and the traction is arranged to happen in vertical direction. This provides the significant advantage that the treatment effect can be achieved by using body mass/weight of the person, and no additional traction force generation devices are needed.

In the embodiments, the arrangement is configured to support the per- son from three support points when using the device. Two of the support levels reside in the device and one on the floor. One of the support points is configured to be against the backside of the person, and another support point at the under- arms. The floor supports the person's feet. The support provided for the person from all points is dependent on the person's position in the device and dependent on the adjustments made by the person to the device.

Figure 1 illustrates one embodiment of a traction apparatus 100 accord- ing to the invention. The traction apparatus is intended to be arranged on a hori- zontal floor and thereby comprises horizontal feet or base 102, 104 arranged to be placed against the floor and thus to support the apparatus to stand on the floor.

Attached to the feet 102, 104, there are also provided vertical cross- bars 106, 108 for supporting other components of the apparatus with respect to the feet 102, 104.

The apparatus comprises a seat rail 110 to which is mounted a seat for S receiving a sitting person. The seat and the seat rail are operatively coupled in N such a way that the seat is capable to move along the seat rail. One way to imple- = ment moving of the seat on the seat rail is to provide rotating rollers between the ? seat and the seat rail. As Figure 1 shows, the seat rail is attached from a first end N to the first vertical cross-bar 106, and from the second end to the second vertical E cross-bar 108.

LO The height positions of the seat rail are preferably adjustable. The ad- > justability can be implemented by either providing several attachment points for N the seatrail on the cross-bars or having the cross-bars themselves to be e.g. tele- N scopic bars.

The adjustability of the seat rail serves for two purposes. On the other hand, the height adjustment provides persons of different sizes to use the appa- ratus. During use of the apparatus, the person sitting on the seat 112 may move the seat by stepping with feet on the floor. Thereby the taller person may desire to set the seat rail and seat higher from the floor than a short person.

The second purpose for the height adjustment(s) of the seat rail is that the seat rail may be set to an angle with respect to the horizontal floor level. For instance, the first end of the seatrail being attached to the first bar 106 may be set vertically higher than the second end at the bar 108. Preferably, the apparatus allows the angle of the seat rail to be set to an angle between O to 35 degrees, preferably between 5 to 25 degrees and even more preferably between 10 to 20 degrees. On the distance of 1 meter of the seat rail, the drop would thus be about cm if the angle would be 15 degrees.

The apparatus may be further provided with a hand rail attachment bar 120 and two hand rails 122 and 124 attached to the hand rail attachment bar. The hand rail bar 120 may be attached to the first cross-bar 106 and is height-adjusta- ble with respect to the first cross-bar. Height-adjustment may be provided by hav- ing the first cross-bar as a telescopic arrangement wherein the inner bar attached to the bar 120 can be adjusted with respect to the outer bar connecting to the base

102. The height adjustment of the bar 120 serves for the purpose of suiting the arrangement 100 for people of different sizes.

The hand rails 122 and 124 may be arranged to substantially the ends of the hand rail attachment bar 120 whereby the hand rails set to both sides of a person sitting on the seat 112 and using the apparatus. The hand rails 122, 124 may comprise respective sleeves 122A, 124A that can move on the rails. The S sleeves that are adapted to be placed under-arm of the person may comprise soft N material such as foam to feel convenient during use of the apparatus. = The hand rails may be angle adjustable similarly as the seat rail. The ? angle adjustment is arranged by providing angle adjustment members in the junc- N tion of the hand rail and the hand rail attachment bar. E When using the apparatus of Figure 1, the user may first set the seat LO rail, and thereby the seat, and the hand rails to suitable height for him/herself. For > traction treatment of the lumbar/back of the person, the user may set the seat rail N and the hand rails to a suitable angle with respect to each other. In one exemplary N embodiment, the user may set the hand rails 122, 124 to horizontal level, and the seat rail 110 to an inclined position. Such an inclined position may be such that the first end of the seat rail attaching to bar 106 may be set higher than the second end of the seat rail 110 attaching to the second bar. During use, when the person sitting on the seat and moving from first end of the seat rail to the second end of the seatrail experiences traction in his/her lumbar/back potentially relieving symp- toms therein.

Even though Figure 1 illustrates the hand rails as straight bars, in an- other embodiment the hand-rails may be curved. In one embodiment, the curvature is Implemented as a parabola-like curvature such that the highest point of the hand rail is in the middle of the hand rail. During use, the user would thus experience highest traction being in the middle of the seat rail where the hand rail would have its highest position. In such embodiment, the seat rail might be arranged to a hor- izontal arrangement.

In another embodiment, the hand rails could be curved but such that the highest point of the hand rail would be experienced at the end of the hand rail. In such embodiment, the traction would be increase rapidly from the beginning and more slowly after the start phase when moving along the hand rails from start to end.

The length of the arrangement and its components such as hand rails and seat rail in horizontal direction may be substantially between 1 meter and 2,5 meters, for instance.

Figure 2 shows a side view of the apparatus of figure 1. In this view, the seat rail 110 and the hand rail 124 are both arranged substantially horizontal di- rections. However, at least one of the seat rail and the hand rails are adjustable by angle such their mutual angle can be set to be between O to 25 degrees, for in- stance. From Figure 2 it can seen that the seat rail and hand rail have substantially S egual length even though the seat rail may be slightly longer than the hand rail.

N Figure 3 shows a top elevation of the apparatus of Figure 1. In some = embodiments, the width of the apparatus defined by the hand rail attachment bar ? 120 and/or the base 104 is roughly between 60 cm to 100 cm. The distance be- N tween the hand rails from each other may be approximately 50 to 70 cm. In one E embodiment, also the distance between the hand rails is adjustable such that the LO hand rails can be attached to different positions in the hand rail attachment bar > taking into account different sized people.

N Figure 4 shows a view from the first end, that is from the end having the N first vertical bar 106.

The device according to the invention is especially advantageous in avoiding complex means of attaching the person to a horizontal traction apparatus and being able to utilize the person's own weight in the traction treatment.

Figures 1 to 4 show one embodiment of the arrangement according to the invention.

In a second embodiment, the arrangement comprises a seat arrange- ment which may be similar than that shown in Figures 1 to 4. That is, there may be a seat that is movable on a seat rail. The seat rail may be arranged to a hori- zontal position or to a slight (10 to 20 degrees, for instance) angle with respect to the horizontal plane. Instead of the hand rails to be positioned underarm as in Fig- ures 1 to 4, the second embodiment may be provided with, as traction means, rings to be arranged around the arm or a band to be wound around the person's chest. In the second embodiment, the rings/band may be provided with ropes hanging from the roof, for instance. The arrangement may be provided with “hand rails”, which in this embodiment could refer to rails attached to the roof of the room/build- ing.

In the second embodiment, preferably the hand rails attached to the roof are horizontally arranged, whereby the traction effectuating angle between the hand rail and seat rail is achieved by placing the seat rail to an angle with respect to the horizontal level. When the user moves on the seat rail, the rings or band hanging from the roof and moving along the hand rails cause traction to person's lumbar, which traction has preferably linearly increasing/decreasing magnitude as the function of the person's position on the seat rail.

The first and second embodiments have in common the feature, that the person's upper support position being underarm or on the chest, moves along and in conjunction with the movement on the seat rail.

N In an aspect, there is provided a lumbar traction arrangement, comprising move- = ment means arranged to receive a sitting person and arranged to allow movement 2 of the person; and traction means operatively coupled to the movement means N causing variable vertical traction to the person's lumbar during movement provided E by the movement means. That is, the person is received in the device, on a seat, LO in a sitting position. The seat is then movable and during that movement the trac- > tion means effectuates variable traction to the person's lumbar.

N In an embodiment, the vertical traction is arranged to change linearly N during movement provided by the movement means.

In an embodiment, in the movement means comprises a linear longitu- dinal direction, and the traction means comprises a linear longitudinal direction, and the linear longitudinal directions of the movement means and the traction means are arrangeable to an angle with respect to another. Preferably the move- ment means and traction means comprise bars or rails, which are linear and set- table to an angle with respect to each other. In some embodiments, either the seat rail or the traction rail is arranged to a horizontal position and the other one is in angle with respect to the other one. However, it is also possible to set both rails/bars to an angle with respect to the horizontal plane.

In an embodiment the arrangement is configured to receive the person in a position where the person's spine is at least substantially in a vertical position. That is, during use the person is arranged to sit in the device, and the variable traction force is arranged to happen in at least substantially vertical direction whereby his/her spine is at least substantially vertical position.

In an embodiment, the arrangement is configured to support the person from the backside, and both underarms during use. That is, the person's backside is supported by the seat of the device, and the person's underarms are supported by hand rails or by rings hanging from a rail that can be arranged to a roof of the room, for instance.

In the embodiments, the movement means comprises a seat arranged to receive a sitting person, and a seat rail operatively connected to the seat allow- ing the seat can move along the seat rail. The seat may be arranged to move on the seat rail by means of rollers/rolls, for instance, arranged either to the seat and/or the rail.

In an embodiment, the traction means comprises hand rails arranged o vertically higher than the seat rail, the hand rails being adapted to provide vertical O support to the person when moving on the seat rail. Preferably the hand rails sup- At port the person under both arms. The hand rails may have sleeves that are mova- 2 ble along the hand rails to reduce friction and comfort for use. N In an embodiment, at least one of the seat rail and the hand rails are E provided with angle adjustment means enabling setting the seat rail and hand rails LO to an angle with respect to each other such that when the person sitting on the > seat moves along the seat rail, the hand rails arranged to an angle with respect to N the seat rail cause variable traction to the lumbar of the person. The seat rail and N the hand rails may be adjustable to an angle between O to 35 degrees, preferably an angle between 5 to 25 degrees, more preferably to an angle between 10 to 20 degrees, more preferably to approximately an angle being 15 degrees between each other.

In an embodiment, the seat rail and/or the hand rails are straight bars or rails.

In an embodiment, the hand rails are curved and the seat rail is straight whereby movement on the straight seat rail causes vertical traction to the upper body of the person. The highest point of the curved hand rails may be arranged to the middle of the hand rails or at one end of the hand rail.

In an embodiment the seat rail has a length between 50 cm to 200 cm, more preferably between 70 cm to 150 cm.

In an embodiment, the traction means comprises a second rail arranged above the person, and ropes arranged to move along the second rail, the traction means further comprising attachment means to attach to the person's upper body, preferably implemented as rings to be positioned around the person’s arms or as a belt to be arranged around the person's chest, and which second rail and the movement means are arrangeable to an angle with respect to each other such that variable traction is effectuated to the person moved by the movement means. That is, instead of having rails to be placed underarm of the user, the support to the traction force may be provided from above the person.

In an embodiment, the arrangement comprises a room, and the second rail is arranged to the roof of the room.

In an embodiment, the traction means comprises a fixed attachment point, and a flexible rope attached to the fixed attachment point, and the second end of the rope comprises attachment means to attach to the person, whereby when the arrangement is used and the person moves by the movement means, o the flexible rope is arranged to cause variable traction to the person's lumbar. That N is, the attachment point may be horizontally above one end of the seat rail. When = the user moves on the seat rail towards the second end, the traction force in- 2 creases as the tension in the rope increases thereby causing traction to the per- N son's lumbar.

E It is evident that when the technology develops, the invention can be LO implemented in other ways. The invention and the embodiments are thus not lim- > ited to the preceding embodiments but can vary in the scope of the attached N claims.
