Description

(1) The invention is explained in more detail below on the basis of illustrative embodiments depicted in the drawing, in which:

(2) FIG. 1 shows a partial front view of a patient wearing a hemiparesis orthosis;

(3) FIG. 2 shows the view in FIG. 1 obliquely from in front;

(4) FIG. 3 shows the view in FIG. 1 from the rear;

(5) FIG. 4 shows a view of an elbow orthosis as a separate part;

(6) FIG. 5 shows a view of a wrist orthosis as a separate part;

(7) FIG. 6 shows a view of the wrist orthosis from FIG. 5 fitted on the arm of a patient;

(8) FIG. 7 shows a view of a holding element of an elbow orthosis in an alternative embodiment to FIG. 4;

(9) FIG. 8 shows a section through the holding element according to FIG. 7.

(10) The hemiparesis orthosis shown in FIGS. 1 to 3 is composed of a shoulder joint part 1 and an elbow part 2, which are connected to each other by a connecting band 3.

(11) The shoulder joint part 1 is composed of a textile bandage as holding element 4 which, from above, extends over the shoulder joint, the ball of the shoulder, and the upper arm of a patient 5. A larger arm 6 narrowing conically across the front of the patient extends over the upper chest area of the patient 5. At its end is secured a securing band 7, which serves as a flexible securing means. As FIGS. 1 and 3 illustrate, the securing band 7 extends around the body of the patient 5 and is guided under the armpit on the healthy side of the patient. On the patient's back (FIG. 3), the securing band 7 extends obliquely upward to an arm 8 of the textile bandage 4. There, the securing band is guided through an eyelet 9 and is fixed on itself via a triangular, arrow-shaped widened end 10. For this purpose, the relevant faces of the securing band 7 and the arrow-shaped end 10 are provided with corresponding parts of a velcro fastener.

(12) The textile bandage 4 extends onward with another arm under the armpit on the paralyzed side of the patient 5 and is likewise provided there with a securing band 12 as a flexible securing means. The securing band 12 extends around the upper arm on the inner aspect thereof and, after looping round the upper arm starting from the back of the patient 5, lies on the textile bandage 4 and is fixed there, for example once again with a velcro fastener.

(13) On the face directed away from the body of the patient 5, the textile bandage is provided with several expansion parts 13, which can be sewn onto the textile bandage. The expansion parts 13 may be referred to as elastic expansion members or at least one elastic expansion member. A first expansion part 13.1 extends from the front to the back of the patient 5 over the upper face of the shoulder. On the back of the patient 5, the expansion part 13.1 ends in the area of the arm 8 present there, as is shown in FIG. 3. On the front, the expansion part 13.1 is adjoined by a further strip-shaped expansion part 13.2, which extends into the area of the arm 6 of the textile bandage and ends near the point where the securing band 7 is secured on this arm 6.

(14) A further expansion part 13.3 is provided in the upper arm area and extends perpendicularly with respect to the longitudinal extent of the humerus of the patient 5. It will be seen that the securing band 12 is secured in the area of the expansion part 13.3. Extending between the expansion parts 13.1 and 13.3, there are also adjusting bands 14 with which the curvature of the textile bandage 4 can be adapted to some extent to the patient 5.

(15) The expansion parts 13 are composed of flat, thin and elastic plastic strips, which are cut out from a flat plastic material. Insofar as they are deformed by the shape of the textile bandage 4, they have a tendency to return to the flat starting position and as such are biased toward a flat position. Thus, the expansion parts 13 pretension the textile bandage 4 when the expansion parts 13 are deformed by the textile bandage 4. In this way, the arms 6, 8 and 11 stand more or less rectilinearly from the rest of the textile bandage 4 when the orthosis is removed from the body of the patient 5 and no tension is exerted between the arms 6, 8 or on the arm 11 via the securing bands 7, 12, respectively. The central portion of the textile bandage 4, from which the arms 6, 8 and 11 issue, is adapted more or less to the shape of the shoulder and the upper arm by darts, this involving only an approximate adaptation to the typical shape of a shoulder joint and upper arm. The textile bandage 4 is fixed on the body of the patient 5 via the arms 6, 8, 11 and with the securing bands 11, 12, which respectively extend round the upper body and the upper arm of the patient 5.

(16) The elbow part is likewise composed of a flat textile bandage as holding element 15, which is formed by a substantially square textile section with four arms 16, as is illustrated in particular in FIG. 4. An eyelet 17 is secured on each of the four arms 16. Two securing bands 18 as flexible securing means are, as non-elastic bands, finished at both ends of their length with arrow-shaped widened ends 19. The arrow-shaped ends 19 are provided on their inner face with a triangular velcro fastener 20, which forms a mating velcro fastener for the inner surface of the securing band 18. For example, the inner surface of the securing bands can be designed with a loop material, while the velcro fastener parts 20 have an associated hook material. The inner surface of the securing bands 18 is the surface onto which the arrow-shaped ends 19 can be turned back for the purpose of fixing them. The inner surface of the securing bands 18 is therefore located on the same side of the securing bands 18 as the velcro fastener parts 20, as is illustrated in FIG. 4.

(17) In the view in FIG. 4, the securing bands 18 are pulled with only one of their arrow-shaped ends through an eyelet 17. In this way, the securing bands 18 do not apply any tension to the arms 16 of the textile bandage 15. The latter is thus pretensioned by an expansion part 21 in a flat starting shape. When the free arrow-shaped ends 19 of the securing bands 18 in FIG. 4 are inserted through the free eyelets 17 in FIG. 4, tension is applied to the textile bandage 15 by the length of the securing bands 18. This bandage 15 is thus bent into a U-shape counter to the pretensioning of the expansion part 21. The respective arms 16 are then connected to each other by a rectilinearly tensioned securing band 18. The arms 16 form ends of the textile bandage 15 of which the opening angle through the securing bands 18 is much greater than the width of the arm of the patient 5 in the area of the elbow. Thus, the textile bandage 15 curved in a U-shape forms, with the securing bands 18, an insert channel into which the hand and the drooping arm of the patient 5 on the paralyzed side can be comfortably inserted, with the bandage 15 being pulled on over the hand and the forearm of the patient 5.

(18) To put on the orthosis according to FIGS. 1 to 3, the elbow part 2 is therefore brought into the described fitting position and hangs down from the shoulder joint part 1. By pulling the elbow part on over the hand and forearm of the patient 5, the elbow part reaches the position on the elbow of the patient 5. In this position, the shoulder joint part can be placed over the shoulder and upper arm of the patient 5. On account of the expansion parts 13, a loop can be formed by the securing band 7 together with the textile bandage 4, and the healthy arm can be placed through this loop, such that the securing band 7, in the securing position shown in FIGS. 1 to 3, can extend under the armpit of the healthy arm of the patient 5 and round the upper body. By then tightening the securing band 12 for looping round the upper arm, the shoulder joint part 8 is fixed in the position of use. The two securing bands 18 of the elbow part are then tightened and finally positioned on the elbow.

(19) In addition, a wrist orthosis can then also be fitted, which is shown in the starting state in FIG. 5 and in the fitted state in FIG. 6.

(20) According to FIG. 5, the wrist orthosis is composed of a substantially rectangular textile bandage as holding element 22, which is strengthened by three textile longitudinal strips 23 sewn onto it.

(21) A substantially X-shaped expansion part 24 extends with four arms 25 up to two strengthening strips 23 on the longitudinal edge of the bandage 22. A through-opening 26 allows a thumb of the paralyzed hand of the patient 5 to be passed through, as is illustrated in FIG. 6.

(22) FIG. 6 does not show the closure of the wrist orthosis with securing strips or the like. This closure is possible in the same way as in the elbow part 2 according to FIG. 4.

(23) FIG. 6 shows that the wrist orthosis is fitted such that the expansion part 24 comes to lie substantially on the inner aspect of the wrist. However, this is not necessarily the case. The wrist orthosis can also be easily fitted from the outside inward and with one hand.

(24) FIG. 7 shows a the elbow orthosis according to 4, in which the holding element 15 is formed by the expansion part 21 itself. The eyelets 17 are thus secured directly on the expansion part 21.

(25) FIG. 8 shows that the expansion part 21 is provided with padded sections 27 on its face directed toward the body part, such that the expansion part 21 can lie comfortably on the body part. As a comparison with FIG. 4 shows, the shape of the expansion part 21 corresponds to the shape of the expansion part 21 on the textile bandage 15 in FIG. 4. Since the textile bandage 15 in FIG. 4 simply has the task of forming the connection to the eyelets 17, the modification in FIG. 7 lies only in securing the eyelets 17 directly to the arms of the expansion part 21. The elbow orthosis according to FIGS. 7 and 8 is fitted in exactly the same way as the elbow orthosis according to FIG. 4.

(26) The illustrative embodiments show that, with the expansion parts 13, 21 and 24 according to the invention, the orthosis can be fitted by one hand, even with more complicated forms of textile bandages 4, 15 and 22, such that the patient 5 can fit the orthosis in place himself and does not rely on assistance from a helper. In the context of the present invention, the holding element 4, 5, 22 can be provided with a dimensionally stable reinforcement, but the latter is not adapted in the circumferential direction to the shape of the body part. For example, in a wrist orthosis, a splint extending in the longitudinal direction of the arm and of the hand can be integrated in the expansion part 21 or in the textile bandage 15.

(27) Of course, the principle of the orthoses set out in the examples can also be applied to ankle orthoses, leg orthoses or also trunk orthoses. In all cases, it is particularly advantageous if the securing bands 7, 12, 18 are held permanently in the eyelets 9, 17 in the manner shown and thereby also cause a pre-shaping of the textile bandage.
