Definitions

  • the invention relates to the field of orthopedic aids, in particular orthopedic stockings and in particular devices which facilitate the handling thereof.
  • Orthopedic stockings also called support or compression stockings, are used, for example, in the aftermath of a thrombosis, for the treatment of varicose veins and "open legs", as well as support in sports and in activities that involve long standing.
  • Rubber gloves are widespread, which have an increased coefficient of friction due to their surface properties, which makes gripping and pulling the support stocking easier.
  • the effort itself, which to refer to Taking off the support stocking is required, however, even when using such rubber gloves, it must continue to be applied over the hands to an undiminished extent.
  • Support stump pretensioning devices are more suitable in this respect, by means of which a part of the support stocking can be clamped on, so that the body part can be pushed into it more easily. Such devices are usually bulky and cannot be used to remove the stocking. In addition, a not inconsiderable amount of time is required to pull the support stocking onto the pretensioning device.
  • Another type of donning aid uses spreading aids which can be moved along the body part. These include rings, on which the stockings are rolled up in a first step and rolled off on the body part in a second step.
  • the documents GB 850165-A , DE 8906458 UI and DE 102004032555 A1 describe tightening aids of this type, whereby, in addition to the underlying concept, the rolling behavior of the ring and the problem of its shape being too rigid are dealt with primarily.
  • US 636636 also a puller with which the stocking can be wound onto the deformable ring before being put on
  • WO 2012/032459 A1 shows an auxiliary device for socks, wherein the auxiliary device comprises a ring, a carrier and an expanding tool. Ring and carrier are coordinated so that a sock attached to the ring can be rolled up by moving along the carrier. With the expanding tool, the opening of a rolled-up sock can be enlarged so that a limb can be better inserted into the opening and the sock can be put on more easily.
  • WO 2012/032459 A1 shows various embodiments of the expansion tool, including one in which the force required for expansion is provided by a motor.
  • DE 69320493 T2 shows a device with which the opening of a stocking can be widened by the device having a so-called organ made of elements with joints.
  • the organ can assume a collapsed starting position in which it can be pushed into the stocking and an unfolded final position in which it widens the stocking.
  • the energy required for the transition from the starting position to the end position is applied by an electric motor.
  • This electric motor together with a rod to which the organ is attached, can produce a pulling movement for covering the stocking.
  • US 8356735 B1 teaches a carrier to which a wound stocking can be attached and which can be placed in a device with a motor.
  • the carrier, device and motor are designed such that a leg can be positioned in such a way that the stocking is attracted by a movement of the carrier fed by the motor along the device.

  • the device is referred to below as a putting-on aid.
  • this expression has no restrictive meaning and in particular does not exclude the removal of a support stocking and any preparatory steps, such as, for example, rolling the support stocking onto a donning aid or on parts thereof or positioning the donning aid or parts thereof.
  • One embodiment of the donning aid has a carrier element, the surface of which comes into contact with the support stocking, and at least one motor.
  • the at least one motor sets parts of the carrier element, for example parts of this surface, in motion, wherein this movement can at least support a rolling off and rolling up of the support stocking after the support stocking and support element have been brought into contact with one another in a certain relative position.

  • These elastic elements include an element which is designed to generate an internal stress in the carrier element.
  • the internal stress leads to a contraction of the carrier element, which in particular causes a reduction in the area in which the body part is in operation and which is defined by the shape of the carrier element.

Furthermore, the adjustment mechanism has an adjustment motor and an adjustment gear, which is driven by the adjustment motor.

  • the guide jaw is designed so that it holds the carrier element in a certain position relative to the guide jaw, but the movement of the carrier element, which causes the support stocking to roll and unroll, is not hindered.
  • This can be accomplished, for example, by the guide jaws having rollers, the carrier element surrounded by the support stocking being essentially only in direct contact with these rollers and being held and held in position by these rollers.

  • the propulsion unit 5 is made of an elastic material, for example rubber or an elastic plastic.
  • the propulsion unit 5 itself is in direct contact with a propulsion connection piece 6, which in the embodiment shown is designed as part of a drive unit 3.
  • Each drive unit 3 is designed in the shape of a cylinder, the propulsion connector 6 forming the jacket of the cylinder.
  • the propulsion connector 6 is driven via a planetary gear, comprising a sun gear 4.1 and a planet gear 4.2.
  • the propulsion connector 6 has internal toothing in some areas (see also FIG Figures 6-8 for detailed representations). Via this toothing, the jacking connector 6 is driven by two, three or more planet gears 4.2.
  • the sun gear 4.1 itself is connected via a drive shaft 14 to a drive motor 13, which is spatially limited by a motor housing 13.1, and can be rotated by the latter.
  • the rotating parts of propulsion connector 6, planetary gear 4 and drive shaft 14 are supported by non-rotating parts via a bearing 11, which does not prevent the rotational movement of these parts.
  • the non-rotating parts include a fixing block 8, one or more connecting elements 9 and the motor housing 13.1.
  • the connecting elements 9 are anchored in the fixing block 8. It is these non-rotating parts that give the support element 7 the necessary stability by being torsionally stable and pressure-resistant.
  • Figure 6 uses a central longitudinal section through the cylindrical drive unit 3 to illustrate the structure of the same as in a carrier element 7 according to FIG Figure 5 can be used, in detail.
  • the arrangement of the moving parts drive shaft 14, planetary gear 4, which has a sun gear 4.1 and a planet gear 4.2, and propulsion connector 6 is shown.
  • the arrangement of the non-moving parts motor housing 13.1, fixing block 8 and connecting element 9, which in the embodiment shown is located in a plane in front of and / or behind the cutting plane, is shown.
  • a bearing 11 transfers the mechanical stability of the non-moving parts to the moving parts without hindering their rotational movement.
  • the propulsion connector 6 is driven in the area of the planetary gear 4.2. In this area, the jack connector 6 is serrated on the inside. This allows sun gear 4.1, planet gear 4.2 and propulsion connector 6 in the in Figure 6 Embodiment shown as a planetary gear in stand translation.
  • the propulsion unit 5 is in flat, rotationally fixed contact with the propulsion connection piece 6.
  • the propulsion connection piece 5 can also be dispensed with by appropriate design of the inside of the propulsion unit 5.
  • knobs 10 or other elements such as hooks or clamps or a non-slip coating which promote interlocking of the support stocking 2 with the propulsion unit 5 and thus prevent the support stocking 2 from slipping off and the carrier element 7 from rotating empty.
  • Figures 7 and 8 show cuts along the in Figure 6 indexed levels.
  • Figure 7 shows in a section along BB in more detail how the rotation of the drive shaft 14 caused by the drive motor 13 is transmitted via the planetary gear 4 to the propulsion connector 6 and the propulsion unit 5.
  • the connecting elements 9 penetrating the sectional plane.
  • the fixing block 8 itself has no area which is located in the sectional plane.
  • Figure 8 shows in a section along AA also in detail how the rotating parts propulsion connector 6 and propulsion unit 5 via the bearing 11 are carried by the non-rotating parts motor housing 13.1, fixing block 8 and connecting element 9.
  • Figure 9 schematically shows the interior of an embodiment of the carrier element 7.
  • the carrier element 7 has, in addition to drive units 3 and connecting elements 9, an elastic element 46, an adjusting mechanism 40, a sensor 47 and an opening / closing mechanism 48.
  • the elastic element 46 provides tension along the longitudinal axis of the carrier element 7.
  • a carrier element 7 is shown in the form of a rotation torus, with which the said longitudinal axis of the carrier element 7 is identical to the circular line 21 of the rotation torus. This tension leads to a clamping effect on the body part surrounded by the carrier element 7 during operation, which ultimately allows the carrier element 7 to be moved up and down along the body part.
  • the sensor 47 measures the tensile force occurring along the longitudinal axis 21 of the carrier element 7 and sends a signal to the adjustment mechanism 40 as soon as a value falls below a predefined minimum value or is exceeded a previously defined maximum value.
  • a contraction of the adjustment mechanism 40 along the longitudinal axis 21 of the carrier element 7 is initiated by the signal.
  • an expansion of the adjustment mechanism 40 along the longitudinal axis 21 of the carrier element 7 is initiated accordingly.
  • the opening / closing mechanism 48 ensures that the carrier element 7 can be opened, for example in order to simply remove the carrier element 7 from the body part after the support stocking 2 has been put on, or to position the carrier element 7 on the body part before the support stocking 2 is removed.
  • FIG 10 A schematic representation of an embodiment of an adjustment mechanism 40 is shown, which serves to enlarge or reduce the area which is at least partially enclosed by the carrier element 7 during operation.
  • it is a section perpendicular to the axis of rotation 18 which contains the longitudinal axis of the carrier element 7 or the circular line 21 of the rotation torus.
  • the connecting elements 9 which change their length parallel to the longitudinal axis of the carrier element 7.
  • the adjusting mechanism 40 is arranged between two connecting elements 9 which run straight and parallel in the region of the adjusting mechanism 40.
  • the two connecting elements 9 are interrupted perpendicular to their longitudinal axis, as a result of which a first partial connecting area 44 and a second partial connecting area 45 are created.
  • these partial connection areas correspond in the embodiment shown these partial connection areas to the previously introduced partial elements of the adjustment mechanism.
  • the termination of these two partial connecting areas 44/45 is formed by a first fixed connecting piece 43.1 and a second fixed connecting piece 43.2.
  • the first connecting piece 43.1 arranged in the first partial connecting area 44 carries an adjusting motor 41 and an adjusting gear 42, which at least partially has a thread.
  • the connecting piece 43.2 arranged in the second partial connection area 45 has a threaded bore which is matched to the thread of the adjusting gear 42.
  • the adjustment gear 42 can now be rotated via the adjustment motor 41, as a result of which the distance between the two partial connection areas 44/45 and thus the distance between the two fixing blocks, in which the connection elements 9 involved in the adjustment mechanism 40 on their side facing away from the adjustment mechanism 40 are anchored, changed.
  • the adjustment mechanism 40 shown can be both an independent element within the carrier element 7 and a component of a drive unit 3.
  • FIGS 11 and 12 show two embodiments of carrier elements 7 which have an adjustment mechanism 40.
  • the adjustment mechanism 40 is integrated in the drive unit 3.
  • the area of the carrier element 7 in which the carrier element 7 has no bend is lengthened or reduced.
  • a support element 7 is thus realized which is able to at least partially enclose a body part, the at least partially enclosable surface being adjustable via the adjustment mechanism 40.
  • Figure 12 schematically shows the inner life of a carrier element 7, which is able to completely enclose a body part.
  • drive units 3 and units of the adjustment mechanism 40 are arranged alternately on the sides of an n-corner.
  • a hexagon is shown in the figure, even if geometric shapes with a higher number of corners and / or rounded corners are better able to reproduce the cross-sectional shape of a body part.
  • the drive units 3 themselves also have an adjustment mechanism 40.
  • the shape of the carrier element 7 can be adjusted more precisely.
  • Figure 13 shows an alternative embodiment of a donning aid 1 with guide rail 17 in operation, which is also in accordance with the invention.
  • a state is shown in which the support stocking 2 is only partially pulled onto the body part, here the leg.
  • the support stocking 2 is not rolled up on the support element 7 covered by the support stocking 2 before it is unrolled, but rather is only stretched by the support element 7.
  • Figure 14 is a schematic detailed representation of the donning aid 1 according to Figure 13 .
  • the surface of the carrier element 7 has both partial areas which perform a circumferential movement and partial areas which do not make a circular motion.
  • the latter have a foot 25 and an extension 26, the extension 26 extending along the axis along which the pulling aid 1 moves to unwind and roll up the support stocking 2.
  • the non-circulating sub-regions enable the connection of the carrier element 7 to the guide rail 17 without using a guide jaw. Furthermore, these areas create space to easily accommodate components of the tightening aid 1, such as driving motors, gears, propulsion connectors and holding and / or supporting elements. In the embodiment shown, the drive units are accommodated in the foot 25.
  • the surrounding sub-areas have the propulsion unit 5, which is designed in the form of treadmills, which sub-areas of the extension 26 run around.
  • a propulsion unit 5 is driven from the outside, that is to say from an area which does not enclose the self-contained propulsion unit 5. This happens because the propulsion unit 5 has areas into which hooks, or teeth or guide pins, which are on the propulsion connection piece 6 (in Figure 14 are hidden by the housing of the foot 25 and the propulsion unit 5). The rotational movement of the propulsion connector 6 driven by a motor is thus transmitted to the propulsion unit 5.
  • the propulsion unit 5 alternatively driven from the inside, ie from an area which will be rotated by the propulsion unit 5.
