Definitions

  • the invention relates to a device for moving the legs with a crank mounted on a fixed frame, with pedals mounted thereon and with a device for firmly connecting the feet to the pedals.
  • the focus here is on movement devices in which the crank - at least optionally - is driven by a motor. This allows the patient's weak or paralyzed lower limbs to be moved passively. This is of great practical importance especially for wheelchair users. The passive movement also stimulates the bowel and bladder functions.
  • the invention has for its object to better adapt devices of the type described in the introduction to the needs of wheelchair users, in particular with a view to the fact that they can use the device themselves without outside help.

This is of great practical importance especially for wheelchair users. The passive movement also stimulates the bowel and bladder functions.
  • the invention has for its object to better adapt devices of the type described in the introduction to the needs of wheelchair users, in particular with a view to the fact that they can use the device themselves without outside help.
  • a spring-loaded clamping device which can be actuated by means of a hand lever is provided on the pedals, the pressure piece of which comes to rest on the back of the foot, preferably in the vicinity of the foot root.
  • the actuating lever can be shaped and extended so far that the wheelchair user can reach it by hand and thereby operate the clamping device itself.
  • the structural design of the clamping device is preferably chosen so that a lever mechanism is provided which carries the padded pressure piece and can be pivoted outwards transversely to the foot and which snaps into the clamping position.
  • the pressure piece adapted to the shape of the back of the foot must, however, have a sufficient spring stroke in order to both undress and to hold a shoed foot comfortably but securely and firmly enough on the pedal.
  • the lever mechanism can be attached to a lever mounted on the outside of the pedal and extending in the longitudinal direction of the foot, which has a length sufficient for the required stroke and is loaded, for example, by means of a longer compression spring guided on a pin.
  • leg brackets in particular support shells for the lower leg
  • tensile elements acting upward on these leg brackets.
  • this compensates for the weight of the legs and, on the other hand, the knee joints are guided so that they cannot move sideways. Above all, however, limiting the downward movement of the knees prevents the legs from falling into a fully extended position, in which the knee joint is known to be blocked and the crank from running smoothly.
  • the tension members are elastic ropes attached to the frame, e.g. B. rubber fabric hoses that have a steel core to limit the expansion. These ropes can be changed in their effective length by means of a lockable retractor. The ropes also do not have to be hung above the eye level of the user of the device, so that the field of vision is not impaired.
  • the ropes are wound on a rotatably mounted and lockable shaft on the frame, the ends of which serve as handles, as a result of which the handle bar common in such devices is developed into an adjusting device .
  • the shaft can be locked using a clamping screw, which is also located in the handle area.
  • Another aspect in connection with the independent use of such a device by wheelchair users is the muscle cramps (spasms) which often occur.
  • a physiotherapist or other qualified person who turns the crank to mobilize a patient's legs adjusted for the appearance of spasms. She feels the muscle resistance and tries to release the spasm by turning it in the opposite direction.
  • a further improvement of the device in terms of independent usability is therefore that the apparatus automatically understands the behavior of the auxiliary person. This can be achieved by firstly continuously adjusting the maximum torque output by the engine.
  • an automatic electrical control device is provided, which reverses the direction of rotation of the motor when its maximum torque or any adjustable torque is reached.
  • the precise and sensitive adjustability of the reversal point is also important in view of the fact that cranks with an adjustable diameter are known and the crank diameter must be matched to the leg mobility of the patient concerned.
  • the device according to Figures 1 and 2 comprises an H-shaped frame seen from the side with an upstanding, length-adjustable handlebar 1 and two transverse legs 2 with rubber feet 3.
  • Halfway up this frame carries an elongated housing 4, on which one Crank 5 is rotatably mounted about a horizontal axis 6.
  • the crank 5 is driven by an electric motor contained in the housing 4.
  • a total of 7 pedals are mounted.
  • the bearing axles of the pedals are labeled 8.
  • the pedals 7 each consist of a footplate 9, a shield 10 shielding the foot from the crank 5 and a curved heel support 11, which parts are firmly connected to one another.
  • a cross shaft 14 is rotatably supported, the end portions of which are designed as handles 15.
  • this cross shaft are two rubber ropes 16 with one end each consolidated and wound up a bit.
  • the two other ends of the rubber sleeve are attached to the upper ends of the connecting rods 12 and to the calf shells 13.
  • the cross shaft 14 can be locked by means of a clamping screw 17.
  • the handle bar 1 carries a small table top on which an electrical control unit 18 for the drive motor contained in the housing 4 is built.
  • the operating elements of this control device 18 indicated in the drawing are arranged on the user side and are therefore also located in the grip area, where they are easily accessible.
  • Fig. 3 shows the pedal 7 with the foot of the user and a clamping device in the clamping position.
  • the base plate 9, the shield 10 and the heel support 11 indicated in section are found.
  • the clamping device consists of a spring lever 20 mounted at 19 on the base plate 9, at the free end of which a bearing piece 21 designed as a double plate is fastened transversely and obliquely.
  • a guide pin which passes through the spring lever 20 is also articulated at 22 on an edge of the footplate 9.
  • a compression spring 23 is wound around it, which is supported at the top by an adjusting screw 24 and presses on the spring lever 20.
  • an actuating lever 25 and a shorter clamping lever 26 are mounted on the bearing piece 21, which two levers are connected to each other by an articulated bracket 27.
  • the operating lever 25 is bent towards the user and can be carried out so long that its free end extends into the handle area.
  • the clamping lever 26 carries a padded, slightly arched pressure piece 28, which rests on the back of the foot according to FIG. 3.
  • the open position of the clamping device is shown in Fig. 4 with solid lines. Both the actuating lever 25 and the clamping lever 26 of the right pedal shown protrude approximately horizontally outwards (to the left in the drawing). If the actuating lever 25 is shifted by approximately 90 ° into the intermediate position 25 ′ shown in dash-dotted lines, the clamping lever 26 swivels by more than 180 °.
  • the pressure piece 28 lies on the back of the foot.
  • the link plate 27 is shortly before its dead center and causes a snap effect when the actuating lever is brought a little further into position 25 ". Now the pressure piece 28 is above the link plate 27, actuating lever 25, bearing piece 21 and spring lever 20 under the action of Compression spring 23.
  • FIG. 3 the pivot point 29 of the connecting rod 12 is clearly visible behind the shield 10. It lies as axially as possible with the ankle so that the foot fixed on the pedal 7 can move.
  • a tension spring 30 engages at the projecting end the connecting rod 12 and thus holds the pedal in a central position (approximately right foot position).
  • the pedal bearing is deliberately moved with its axis 8 away from the pivot point 29 further to the toe, since this is the only way to move the ankle and lower leg muscles when turning the crank 5. But that's what matters.
  • the veins of the lower leg have valves similar to those of the heart, so that the changes in the calf muscles - including the passive ones - promote blood circulation (muscle pump).
  • the movement device described can be used by a paraplegic wheelchair user, for example, as follows: He approaches the device from the front and puts his feet on the foot plates 9 of the pedals 7, which are presented ready for entry. The lower legs are located in the calf shells 13 the feet the necessary fixation on the pedals. It is then also assumed that the crank radius is set to the personally possible dimension by means of an adjusting device, not shown. On the controls of the control unit 18, he can now rotate the crank in the desired direction and at the desired rotational speed.
  • the tensile force of the rubber ropes 16 is not sufficient and the knee joints are at risk of being stretched and blocked, he can do so by loosening the clamping screw 17 counteract further winding of the rubber ropes by turning the handles 15 and adjust the tensile forces appropriately.
  • the torque delivered by the drive motor is continuously electronically monitored and, for example, the motor is stopped when a muscle spasm occurs as soon as the torque increasing as a result of the cramping exceeds a certain limit value. In this case, too, a restart of the motor can be programmed in the opposite direction.
  • spasms can be alleviated or completely eliminated by changing the direction of rotation several times at low torques. In any case, the disabled can choose the most comfortable form of movement in many variants. After swiveling the actuating lever 25 out of the device is easily possible.
