Field of the Invention
The present innovation concerns a support arrangement for supporting the arm of a patient in a bent position of the upper arm relative to the lower arm.
Background of the Invention
In surgical operations on the hand it is normally necessary in the postoperative phase to place the lower arm at rest in a bent position relative to the upper arm. Thus the lower arm of a lying patient is normally positioned upward at an angle of 90.degree. relative to the upper arm, lest the hand be supplied with blood in an unnecessarily strong manner. Hitherto this rest position was obtained in the following manner: the lower arm was suspended by a support band on the plaster or on the bandage. The support band was suspended from above, e.g. from a supporting arm on the bed frame, located above the patient. However, this results in tractive forces on the lower arm that are felt as troublesome by the patient.
Summary of the Invention
The task of the present innovation consists in making available a novel type of support arrangement with which the aforesaid disadvantages are avoided and which, in addition, can be produced simply and economically.
This task is accomplished with respect to the generic support arrangement by the fact that the support arrangement includes a holding bag, which on its upper side is attachable in a hanging manner to a support, and that the holding bag on the one hand forms on its lower side a rest for the upper arm and on the other hand forms on its side turned away from the upper arm a rest for the underside of the bent lower arm, so that the lower arm is not extensible within the holding bag or bendable in the direction of the upper arm.
The support arrangement according to the innovation has the advantage that, by virtue of the rest for the lower arm as well as the positioning of the lower arm through the holding bag, no troublesome tractive forces act on the lower arm or its bandage. Vascular congestion, etc. caused by the support is thereby avoided. Beyond that, the support arrangement can be produced with simple means in an economical manner.
By constructing the holding bag from a cut that is sewn up on the top side as well as on the bottom side, for one thing it can be manufactured in an especially simple manner, and for another thing it can be advantageously collapsed, i.e. folded, and thus stored without problem.
The tapered shape of the holding bag on its upper side ensures an optimized application of force from top to bottom, whereby the force on the lower-side rest acts evenly upon the upper arm.
Inasmuch as both sides of the holding bag in the tapered region are formed open, this holding bag can be threaded directly onto a holding rod and at the same time make possible a slight twisting of the bag with respect to the holding rod.
The ability to close the side of the holding bag facing the upper arm has the advantage that after the closing of this side of the arm, which on account of a plaster cast can have an excessive weight, it cannot move towards the upper arm, i.e. unintentionally fall towards the patient and injure him.
For the closing of the side facing the upper arm, provision is appropriately made for at least one cord. However, provision can also be made for at least one pair of cords, which pair consists in each case of one cord attached to each position of the holding bag, which cords are tied together for the closing.
Likewise, for suspending the holding bag from a support at least one fastening cord or pair of cords is appropriately provided for, by means of which cord or pair of cords the support arrangement can be fixed at different heights. In the case of a pair of fastening cords, this can consist of one shorter and one longer fastening cord, whereby a tying together can take place in an accessible and simple manner on the side and not on the upper side of the support.
If the fastening-cord pair is implemented on the underside of a seam that is located on the upper side of the holding bag, a more secure support of the holding bag is ensured, without requiring an expensive stitching or gluing of the cord to the holding bag.
The holding bag is appropriately to be positioned in such a manner that the lower arm located within maintains a lateral freedom of movement, whereby the supplying of blood to the arm placed at rest can be aided by small movements.
For increasing the strength of the holding bag it can be formed double-layered on the side facing the upper arm, preferably over the entire side, and/or on the open side-region of the side facing the lower arm. This leads, on the one hand, to a strengthening of the "open" edge region not sewn up with an opposite side, so that, for example, a tearing of the material is prevented. On the other hand the cords can also be securely attached to the double-layered side facing the upper arm, for example sewn onto it.
The holding bag consists appropriately of textile-like material, whereby it is usable many times and in addition can be cleaned in common within the framework of the usual hospital laundering process.
Appropriately, the length of the tapering region corresponds to approximately a third of the overall length of the holding bag. By this means the holding bag can be employed in one standard size, at least for adults.

An appropriate configuration of the innovation will be explained in more detail in the following, with the aid of the drawn figures. They show:

Detailed Description of Preferred Embodiments
FIG. 1 illustrates the application of the support arrangement at the sick-bed. The holding bag 1 is suspended by a fastening cord 12 from a support 14, which in turn is attached to the sick-bed. Here the upper arm of the patient rests upon the bottom side 2 of the holding bag 1, while the bent lower arm leans against the side 3 turned away from the upper arm. In this way the arm is supported and held in a manner that is secure and conducive to healing.
The upper side 11 of the holding bag 1 is distinguished by a form that is tapered upwards. This tape red or trapezoid-like upper side 11 corresponds to approximately a third of the overall length of the holding bag 1. This form effects an optimized introduction of force from the upper side 11 of the holding bag downwards, so that the force acts evenly upon the upper arm at the bottom side 2.
In FIG. 2, a more precise manner of viewing the holding bag 1 shows cords 5, 6 attached at each position to the side 4 facing the upper arm, whereby in each case two opposite cords 5, 6 can be joined together for a pair of cords.
A tying together of these cord pairs after the inserting of the arm prevents an unintended failing out of the arm in the direction of the patient's head. Also evident is a double-layered side 3 facing the upper arm, which side effects an increase in the strength of this partly open side and prevents a tearing of the edges attached at the side. The tapered region is also open on the side 3 facing the upper arm and is there formed likewise double-layered, in order to prevent, for example, a tearing when the lower arm is leaned against it.
The bottom side 2 of the holding bag 1 is sewn together and thus forms the rest for the upper arm. The upper side 11 of the holding bag 1 is likewise sewn together, with a fastening cord having been sewn into this seam 9. It is easily sewn on in one piece, since in this region both the side turned away from the upper arm and the side 4 facing the upper arm are open. A continuous cord 12 runs under the seam 9 and is fixed in such a manner that it forms on one side a shorter fastening cord 7 and on the other side a longer fastening cord 8. By this means a tying together of the two fastening-cord segments is possible in a simple and accessible manner at the side.
FIG. 3 shows the symmetrical cut 10 of the holding bag 1. By virtue of this symmetry, for one thing the cut 10 is easy to produce and for another it is simple to sew together, after one has folded it along the axis of symmetry 13. The V-shaped cut formed by the two trapezoid-like sections corresponds to the open side 3 turned away from the upper arm, this section--as already explained--being double-layered.
