Abstract
An apparatus for the passive motor rehabilitation of the upper limbs and shoulders, comprising a vertical support structure, along which run vertically the means of movement of the upper limb and/or shoulder of a patient or user, comprising means of control for allowing the user themselves to start/stop said means of movement.
Description
- The present invention essentially relates to the motor rehabilitation sector, with particular reference to the rehabilitation of the upper limbs and shoulders.
- Currently, rehabilitation occurs by means of specially trained personnel (for example physiotherapists) and/or by means of special machinery, usually very expensive and complicated.
- Furthermore, very often, patients must attend the hospital or gymnasium or health facility equipped with such apparatus. The physiotherapist only visits the patients house in certain cases.
- The main scope of the present invention is that of overcoming the aforementioned drawbacks by providing an apparatus that is easily portable, easy to use and simple to manufacture.
- This has been achieved according to the invention, by providing a portable rehabilitation apparatus with a vertical support structure, along which move vertically the means for moving the upper limb and/or shoulder of a patient or user, comprising means of control allowing the user themselves to start/stop said means of movement.
- Greater understanding of the invention can be obtained from the following detailed description and by referring to the enclosed figures which illustrate, purely by way of non-limiting example, several
- In the figures:
- figure 1 is a side view of a first embodiment of the invention;
- figure 2 is a plan view of a partial cross section along trace plan A-A of fig. 1;
- figure 3 is a front view corresponding to fig. 1;
- figure 4 is a side view of a second embodiment of the invention;
- figure 5 is a plan view of a partial cross section along trace plan B-B of fig. 4;
- figure 6 is a front view corresponding to fig. 4;
- figure 7 shows the movement of some of the parts of the invention in the second embodiment; and
- figure 8, like fig. 4, shows a variant of the vertically moving carriage that can also be applied to the first embodiment of fig. 1.
- With reference to the aforementioned figures, the invention comprises: a
lower base 13 onto which is secured a supportingstructural element 10 and a vertical rail, along which run the means of movement of one upper limb and/or one shoulder, as well as acontrol unit 3 for means of operation of the aforementioned means of movement. - In the example shown, said means of movement are essentially constituted by a carriage or
chassis 6 running vertically with an alternating motion along saidvertical rail 10. To saidcarriage 6, is fixed a handle orgrip 4 which the user must grasp in order to perform the passive motor rehabilitation movement. - The
control unit 3 allows the speed of the movement of thecarriage 6 to be adjusted by appropriately controlling the means of activation comprising a motor, preferably electric 2, fitted with appropriate gears, of known type. - According to the invention, it is possible to adjust the rehabilitative movement by means of the
control unit 3 or, more simply, by means of the special upper andlower limit switches 16, which can be moved along thevertical rail 10 as appropriate, in order to change the direction of movement of the motor 2 (for example by operating relays which reverse the polarity of the power supply). - In the preferred embodiment described, said
motor reducer 2 turns anupper pulley 11 which draws a belt orcable 7 held tight by means of alower pulley 8 which turns idly on a hub mounted on a speciallower stay 9. This way, the belt orcable 7 defines two parallel vertical limbs: one descendent (ascendant) and the other ascendant (descendent). Thecarriage 6 is firmly fixed to one of said limbs of the belt orcable 7, so that each rotation of thepulleys carriage 6 itself along the vertical guide andsupport element 10. - The example embodiment described envisages the
cable 7 being fixed to thecarriage 6 by means of one ormore clamps 15. Furthermore, saidlimit switches 16 are preferably activated by corresponding locator elements fixed to thecable 7. - In the figures, said vertical guide and
support element 10 is constituted by two circular cross section tubular vertical arms, and themoveable carriage 6 comprises at least one tube or sleeve, coaxial to one of them. - In order to avoid any undesired rotation of the carriage around the axis of the pole on which it runs, the body of the carriage comprises a transverse forked element adapted to running along the second vertical support pole (figure 2).
- One constructional variant of said carriage envisages that, in place of said forked element, the body of the carriage comprises a second tube or sleeve, fixed to the former, adapted to running along the second vertical pole. In other words, in said variant, the carriage has an essentially "H" shaped body, wherein the two vertical parts are the sleeves, running along the vertical support poles (figure 8).
- It is obvious that unwanted rotation of the carriage around the vertical axis of the guide and support element can also advantageously be impeded by using a single vertical guide and support pole, the shaft of which is characterised by having a polygonal instead of circular cross section, and a carriage, the body of which comprises a sleeve with a matching cross section.
- A second embodiment of the invention, particularly useful for the rehabilitation of the shoulder joint, envisages fixing an
anatomical support 5 for the forearm (figures 4-7) to the vertically moving carriage, in addition to or in place of the hand grip. - Said
support 5 is fixed essentially transversally with respect to thevertical guide element 10. - According to the invention, in this case it is also possible to envisage that said
forearm support 5 has, at the same time as the alternating vertical movement already described, an additional rotational movement which raises/lowers the wrist with respect to the elbow (figures 6-7). - One particular characteristic of the invention comprises said rotational movement of the forearm being obtained by fixing said forearm
support 5 in a way that can be rotated, to the movingcarriage 6 with one end of the support itself hinged to a lower connecting rod B, the opposite end of which is fixed below to the vertical guide andsupport element 10. This way, particularly simple and effective articulated motion is achieved, without any need to modify the means of movement already described. - Since this is an apparatus which must be used in close contact with the human body, it is preferable to use a low
voltage motor reducer 2, thus the means of supplying power comprises atransformer 1 for reducing the voltage of the mains supply to that of said aforementioned motor, for example to 24 Volts. - Finally, one interesting variant of the means of movement of the
carriage 6, comprises - in place of the system ofpulleys carriage 6, thus meaning that each rotation of the screw, driven by themotor reducer 2, corresponds to a given vertical displacement of the screw drive, and hence thecarriage 6 fixed thereto: reversing the direction of rotation of the screw obviously reverses the direction of displacement of the carriage. - The present invention has been described and illustrated in some of the preferred embodiments and variants thereof, but it is obvious that one skilled in the art could effect modifications and/or technically equivalent replacements, without moreover straying from the scope of protection of the present industrial patent.
