Abstract

The invention relates to a heat pad (1) for an orthopedic bandage, in particular a back bandage, wherein the heat pad (1) has an outer shell (2) of a flexible material which forms an interior (2i) in which a heating means (W) for Storage and release of heat energy is arranged, characterized in that in the interior (2i) and / or in or at least one wall (2a) of the outer shell (2) at least one heat pad (1) reinforcing means (3), in particular in the form of a pad, arranged or can be arranged.

Description

The present invention relates to a heat pad for an orthopedic bandage according to the preamble of claim 1.

There are known orthopedic bandages which hold pads of a relatively stable material in certain locations of the body of a person in position and in particular press the pad against the body of the person. Such bandages are z. B. off DE 20210170 U1 . DE 29803417 U1 . DE 10 2005 005 005 B4 . DE 10 2009 000 374 A1 and DE 20 2014 100 413 U1 previously known.

Out DE 20 2014 005 972 U1 For example, there is known an orthopedic bandage having, in addition to reinforcing support means, a transportable, reusable heat applicator which is secured by the bandage at a particular location, e.g. B. in the lumbar region, the person is held, and on the areas where the heat applicator rests warms.

It is also the bandage Lumbamed ^® plus medi GmbH & CoKG known, in which the massage pad is replaced by a "thermal pad", which has identical characteristics to the DE 20 2014 005 972 U1 has known heat applicator. The "Thermal pad" is filled with a latent heat storage material and can be "activated" by means of a bendable metal plate. By "activate" the patent understands the actuation of the metal plate, whereby in this way the amount of heat previously absorbed and stored by the latent heat storage material is returned to the environment.

Object of the present invention is to develop a bandage and their heat pad in such a way that the pad either only warms, only massages and / or supports or exerts all the above functions at the same time.

This object is advantageously achieved with a heat pad in which at least one heat cushion reinforcing agent, in particular in the form of a pad, is arranged or can be arranged in the interior and / or in or on at least one wall of the outer shell. Advantageous developments of this heat pad are obtained by the features of the claims back to claim 1. In addition, a bandage, in particular back bandage, claimed with the heat pad according to the invention.

The heat pad is advantageously characterized by the fact that the heat function and / or support function can be activated. However, the support function is always activated only when the reinforcing agent separated from the heat pad, in particular can be removed from this or taken out of this, and thus for activating again on or in the heat pad can be arranged.

Thus, the heat pad may be formed in one embodiment such that the at least one reinforcing agent which z. B. may be a known pad, in a recess of the heat bag can be introduced and also removed again. In another embodiment, the reinforcing agent, such as. B. the pad, even on an outer wall of the heat pad, z. B. by means of bands, Velcro, etc., are attached. In these two possible embodiments, therefore, optionally the heat pad can take over the mechanical support and massage function provided that the reinforcing agent (s) are arranged in or on the heat pad.

However, it is of course also possible that the at least one reinforcing agent, for. B. in the form of a pad, embedded in the material of the heat pad, in particular is cast, so the reinforcing agent in the interior, in which the heating means is arranged to be inserted. However, it is also possible for the at least one reinforcing means to be embedded, in particular cast, in a wall of the envelope enclosing the interior.

The reinforcing means is advantageously a, in particular wavy, pad. This can be formed by a curved plate. However, it is also possible that a plurality of curved plates are arranged parallel to each other and form the reinforcing means. To reduce weight and to make the pad more flexible, this Materialaussparungen, z. B. in the form of window-like recesses.

The reinforcing means may be made of metal, plastic, titanium or aluminum.

It is advantageous if the outer shell has on its outer front, which is directed to the body of the person wearing the bandage, projections, in particular in the form of beads, part-spherical elevations and / or dams or webs. These have a massage effect and also allow ventilation between the skin and heat pad.

The heating agent may be dipotassium hydrogen phosphate hexahydrate, which is reacted by means of an activator, e.g. B. in the form of a bendable metal plate, can be activated and then emits the previously recorded amount of heat as solidification heat back to the environment. However, it is also possible that the heating means may be a heatable gel or other medium, which may be heated in a water bath, oven or microwave.

The heat pad according to the invention can be advantageously attached to the orthopedic bandage. So it is possible that the heat pad is attached in a bag or by means of fastening straps on the bandage. For charging or heating the heat pad can then be separated from the bandage or taken out of this.

Various embodiments of the heat pad according to the invention will be explained in more detail with reference to drawings.

Show it:

1 : Top view of a first possible embodiment of a heat pad according to the invention;

2 : Pad as a reinforcing agent;

3 : first possible embodiment of a shell for the heat pad according to the invention;

4 : second possible embodiment of a shell for the heat pad according to the invention;

5 Cross section through a heat pad with integrated pad according to 1 ;

6 Cross-sectional view through a heat pad with insertable pad.

The 1 shows a plan view of a first possible embodiment of a heat pad according to the invention 1 which is an outer shell 2 has and in a pad 3 is integrated. The outer shell 2 has outer walls 2a on the the interior 2i enclose, in which the heating means W and the activator 4 , z. B. in the form of a bendable metal plate, are arranged. On its front, which faces the person wearing the bandage, has the shell 2 knob-like projections 2 B , which have a massage effect. The outer edge 3a the pad 3 is completely made of the material of the outer shell 2 surround. The pad 3 has window-like recesses 3b up and is how in 2 can be seen, formed by a thin sheet-like and corrugated material, in particular a sheet metal or plastic material. The pad 3 is mirror-symmetrical to the center line S formed. Of course, you can also be trained differently than in the 3 shown. As a reinforcing means, individual rods or the like of relatively inflexible material can be used. The right representation in 2 shows a cross-sectional view through the pad and shows the wave structure of the pad 3 , In the 2 shown pad is intended for a back bandage, which rests centrally on the spine and this the waves and valleys 3m and 3q having.

The 3 shows a first possible embodiment of a shell 2 for the heat pad according to the invention 1 , where the shell 2 an outer wall 2a for the formation of the interior 2i having. At their front facing the person are web-shaped or dam-like projections, which also caused a massage effect.

In the 4 illustrated second possible envelope 2 shows how the in 1 illustrated case 2 bead-shaped knob-like projections 2 B on.

The 5 shows a cross-sectional view through a heat pad 1 with integrated pad 3 , The pad 3 can be either in the material of the back wall 2w be embedded or in the interior 2i einliegen together with the heating means W.

The 6 shows a cross-sectional view through a heat pad 1 in which the pad 3 in a bag 2t , which in the back wall 2w is incorporated, is insertable. The pad 3 does not come in contact with the heating means W in this training.

Of course it is also possible that the pad 3 also outside the shell 2 can be attached to this, z. B. by means of fastening straps or the like. It is also possible that the shell and the pad have mutually corresponding connection means so that they z. B. can be pushed into each other.
