Definitions

  • Backache is one of the most frequent reasons for sick-leave, and in Sweden alone the costs of medical care and fall in production related to this is estimated to between four and five milliard per year
  • WO 83/03747 shows a back warning means, based on a metal ball rolling into contact with a plate metal by twisting and bending, and thus closing a circuit.
  • the means is attached to the patient's back and warns the patient when he or she is close to a harmful movement
  • this means only gives an indication, i.e. when there is contact. No individual grading is possible since this requires a zero adjustment for each individual and there is not obtained any division of the movements into bending and twisting moments
  • US patent 3 608541 shows a means for detection of spinal bendings consisting of an articulated column which is attached over the spine by means of a corset A thread running through the articulated elements is stretched at bending and then gives a signal.
  • the means gives only one possible adjustment, by the thread, and the indication received gives no picture of the movement.
  • the means is cumbersome to wear
  • EP 0041 807 shows a means and a method for establishing the movability at a joint. The means is based on the conductivity of a material being changed by stretching and on the changes of conductivity being registered-
  • e g- a back bench has been designed for diagnosing and treating back injuries.
  • the bench may be prolonged, rotated and turned.
  • this bench is expensive as well as technically and spaciously demanding
  • An object of the present invention is to provide a means for registration of movements especially round the spine-
  • the means can be designed both as a measuring device, by which a doctor may diagnose the injury, and as a ''warning device", intended to be used daily by the patient himself in order to avoid harmful movements -
  • Another object of the present invention is to provide a means by which both rotating and bending movements in different directions may be separately detected.
  • Yet another object of the present invention is to provide a means that has low production costs and is simple, handy and practical in use-
  • the means according to the invention comprises a vertebral column device consisting of a number of separate vertebrae
  • the vertebrae are held together by means of a through, flexible tension spring, and between the vertebrae are spherical sleeves pivoted in the vertebrae.
  • at least one draw bar runs through the vertebrae for taking up bending movements, preferably three, and at least one rod for taking up twisting movements, preferably one-
  • the means comprises a unit for detecting the position changes of the draw bars or the rods and a fixing unit for attaching the means to the spine.
  • the detection unit comprises a transducer for each draw bar and rod, respectively, for detecting the position changes of it.
  • the idea of the means according to the invention is based on it trying to imitate the spine to the greatest possible extent.
  • the means intended to be attached to the spine by a fixing unit, takes up both bending and twisting movements round the spine by virtue of the included bars and rods and these bending and twisting movements are detected by a transducer for each bar/rod. Every small movement round the spine may be transferred to the means due to the uniting, flexible tension spring and the guiding sleeves.
  • a suitable instrument is connected to the transducers of the means for registration of the different movements. It is also possible to design the means as a warning instrument in which some kind of a warning unit is connected to the transducers e.g. in order to give a signal or an electric impulse to the patient when certain values of the movements have been achieved.
  • the means according to the present invention is especially intended for detection of movements round the spine, and therefore, the detailed specification below relates to such a means even though it is possible to detect movements round other joints.
  • Fig. 1 is a front view of the means according to the invention seen from the side turned away from the spine;
  • Fig. 2 is a sectional view along the line I-I in Fig. 1 showing a separate part of the vertebra sectionated;
  • Fig. 3 is a view of a separate vertebra viewed along the line II-II in Fig. 2;
  • Fig. 4 is a view of the detection part of the means seen from behind and partly in section;
  • Fig. 5 is a view of a band with fastening pins intended to be attached to the patient's spine and is taken from the side facing the spine;
  • Fig. 6 is a side view of the means according to the invention.
  • Fig. 7 is a view of a separate sleeve placed between the vertebrae.
  • a means 1 comprising a vertebral column unit 4 and a detection unit 5.
  • the vertebral column unit 4 is made of a number of specific, separate vertebrae 6. Such a specific vertebra is shown sectionated in both Fig. 2 and Fig. 3, and will be further explained below.
  • a sleeve is shown in Fig. 7, and can be closest described as a ball sleeve.
  • An aperture 17 passes through the sleeve.
  • a closely spun tension spring 19 made of rolled spring wire runs centrally through the vertebrae 6 and the sleeves 12 and holds together the entire vertebral column unit with light spring force, and by virtue of its flexibility it causes the vertebral column unit to closely follow the movements of the spine.
  • the outer diameter of the tension spring is principally the same as the inner diameter of the holes 17 in the sleeves 12, implying that the sleeves are fixed round the tension spring.
  • a torsionally rigid torsion rod 20 runs with clearance inside the tension spring 19, and symmetrically round the tension spring run draw bars 18.
  • the draw bars 18 run outside and parallel with the sleeves 12 but through the vertebrae 6, and are intended for taking up bending movements round the spine.
  • the centrally placed torsion rod 20 is intended for taking up twisting movements round the spine.
  • Each single vertebra 6, one of which is shown in Figs. 2 and 3, respectively, has through holes 7 and 10 for the draw bars 18, the tension spring 19, and the torsion rod 20, respectively.
  • the vertebra 6 of Fig 2 it is clear that the upper part of it, earlier defined as the front side 2, in the shown embodiment has bevelled edges. Other forms are of course possible since the form is not crucial.
  • the vertebra 6 On the reverse side 3 of the means the vertebra 6 has a recess 13, intended for receiving a fastening pin 16, fixed to a band 15, which will be described later.
  • the recess 13 and the pin 16 have preferably complimentary forms, but, of course, the exact design can vary. There has to be a certain clearance between the fastening pin 16 and the recess 13 so as to enable the vertebral column unit to run along the band 15 when the means is taken away from or applied to the patient, and as the skin and the band extend in bending.
  • a counterbore or a guiding seat 11 At the mouth of the through hole 10 on each side of the vertebra 6 is a counterbore or a guiding seat 11, in which the intermediate, spherical sleeves 12 are lodged.
  • both the uniting tension spring 19 and the torsion rod 20, which runs within the tension spring 19, run through these holes 10.
  • the holes 10 in the vertebrae 6 have a diameter larger than the diameter of the tension spring, and thus, clearance is provided for the spring.
  • the diameters of the tension spring 19 and the holes 17 of the sleeves are essentially the same so that the sleeves are fixed on the tension spring.
  • the through holes 7 for the draw bars 18 have a thin guiding part 8 in the centre of the vertebra 6 and thicker clearance parts 9 round this guiding part 8. This is shown in Fig. 3.
  • the diameters of the holes in the guiding parts are essentially the same as the diameters of the draw bars 18, which means that the draw bars 18 are guided by these thin guiding parts.
  • the diameters of the thicker parts 9 are larger than the diameters of the draw bars 18, which allows of the clearance of the bars at bending.
  • the tension spring 19 is anchored in the detection unit 5 and in the uppermost vertebra, especially designated with the reference numeral 23. It can also be made as a larger, fixed unit.
  • the tension spring 19 is Lightly stretched at the attachment in order to hold together the vertebral column with a certain spring force.
  • the vertebral column unit 4 is connected at its lower end to the detection unit 5 by a last spherical sleeve 12 and the tension spring 19.
  • both the draw bars 13 and the tension rod 20 are connected to a transducer, the potentiometers 21 and 22, respectively, in the detection unit 5. Furthermore, the draw bars 18 and the tension rod 20 are anchored in the uppermost vertebra 23, preferably by clamping screws allowing a length correction at calibration. Furthermore, the upper, fixed vertebra 23 is conveniently designed open at the top so as to obtain free access to the draw bars and the torsion rod for fine adjustment or possibly replacement.
  • potentiometers At bending and twisting of the means the potentiometers are affected and this change may then be transferred to a suitable registering instrument.
  • Fig. 5 shows a fixation unit 14 comprising an elastic band 15 and fastening pins 16 arranged thereon.
  • the elastic band 15 is provided with an adhesiv on the reverse side, i.e. the side to be attached to the patient's back, and e.g. a covering paper, which can be torn away.
  • the band 15 easily sticks to the patient's back and then the means 1 is threaded over the fastening pins 16 via the recesses of the vertebrae 6.
  • the band 15 runs all along the vertebral column unit 4, while, conveniently, the detection unit 5 is attached to the patient's back with Velcr ⁇ -' fastening.
  • the elastic band has fastening pins 16 and there should be at least as many fastening pins as separate vertebrae 6, each fastening pin engaging each separate vertebra in accordance with Fig. 2. It is essential that all of the means closely abuts the patient's back in order to obtain correct values.
  • Fig. 6 is a side view of the means according to the invention, and with dashed lines it is chiefly shown how the means may be bent forwards and backwards. Returning to Fig. 1, also this figure shows the flexibility sideways of the means, and the swivelling feature is indicated with the arrow F.
  • a registering instrument (not shown) as well as some kind of warning unit (not shown) may be connected.
  • the registering unit is used by the doctor in order for him to establish a clear picture of the patient's trouble, while the warning unit is used when the patient is wearing the means, in order to warn the patient by e.g. a sound signal or vibration signal or to draw his or her attention to the fact that a certain movement is incorrect or even harmful.
  • the separate vertebrae should be made of a durable and above all a light material, a preferred material being plastic.
  • the means may comprise a varying number of draw bars and torsion rods, however, at least one of each, but according to a preferred embodiment it comprises three draw bars and one torsion rod.
  • the means according to the present invention works in the following way.
  • the means 1 is attached to a patient so that it covers the portion of the back to be subjected to the measurment, e.g. the loin.
  • the detection unit 5 is attached to the patient's back with a Velcro fastening. Due to the attachment of the vertebral column unit over the fastening pins 16 on the band 15 the vertebral column unit can easily be drawn from and displaced along the band when necessary and can easily slide along the band with unchanged abutment as the skin is prolonged at bending.
  • the draw bars and the torsion rod are calibrated after each individual patient. Then when the patient bends or twists or makes a combined movement the vertebral column unit follows the movements of the spine and via the included draw bars 18 and torsion rod these movements are transferred to the transducers of the detection unit.
  • a twisting movement affects the potentiometer 22 while different bending movements affect the potentiometers 21. In most cases a movement is a combination of bending and twisting and the great advantage of the present means is then that this combination of movements may be divided into a number of values, showing bending forwards and backwards, bending sideways to the right and to the left, and twisting to the right and to the left, respectively.
  • the means may also be used as a warning instrument and instead of connecting it to a registering unit of the detection unit it may be connected to some kind of warning unit, e.g. a unit having a tone generator or a unit having an oscillator.
  • the means is constructed in exactly the same way when used as a warning device and as a measuring instrument, but instead of measuring different movements the warning device is designed to warn the patient when certain preselected values are reached. Conveniently, the adjustment is made such that the patient is warned before a harmful position is reached.
  • the back measuring and warning means is intended for applying over the vertebrae of the spine at the loin, however, the instrument may of course be designed, according to the same principle, to fit also over the remaining portions of the spine.

Abstract

L'organe décrit (1), qui sert à détecter les changements de position autour d'une articulation telle que notamment la colonne vertébrale, comprend une unité de colonne vertébrale (4) composée d'un certain nombre de vertèbres (6) et d'anneaux (12) séparés, ainsi qu'une unité de détection (5). L'unité de colonne vertébrale est maintenue assemblée par un ressort de tension (18) parcourant toute la longueur des vertèbres et des anneaux. Les vertèbres (6) sont en outre traversées longitudinalement par au moins une barre de traction flexible (18) destinée à absorber les mouvements de flexion et par au moins une tige de torsion (20) destinée à absorber les mouvements de torsion. L'unité de détection (5) sert à détecter les changements de positions des barres et des tiges. L'organe est fixé adjacent au dos d'un patient par une unité de fixation (14) le long de la partie du dos destinée à faire l'objet de la mesure et les différents mouvements de flexion et de torsion peuvent ensuite être détectés par l'unité de détection. A l'unité de détection est connectée une unité d'enregistrement des valeurs. L'organe peut également être utilisé comme organe avertisseur, auquel cas une unité d'avertissement, au lieu de l'unité d'enregistrement, est connectée à l'unité de détection.
