Pad for holding a bandage and bandage

Description

[0001] The invention relates to a pad designed to be incorporated into a bandage and intended to support body tissue, having ventilation channels on the side facing the body. The invention further relates to a bandage.

[0002] Such a pad is known from DE 20 2014 003 965 U1. This patent describes a pad with a base, on which contact elements are formed in a regular arrangement, each having a triangular contact surface. Ventilation channels are formed between the contact elements, extending between two opposing edges of the pad and intersecting at an angle of 60°. Openings are arranged in the base at the intersections of the ventilation channels, allowing the evaporation of liquid, particularly perspiration, that forms between the body tissue being supported and the contact surfaces.

[0003] Another pad is known from DE 44 39 088 A1. In this design, the support bodies are square. Overall, this achieves support that is as pressure-free as possible. The separation of the support bodies by canyon-like incisions results in high surface elasticity, thereby providing support for the limbs and extremities that is as free from pressure peaks as possible.

[0004] The invention is based on the objective of creating a pad and a bandage of the type mentioned above which have a particularly high elasticity.

[0005] This problem is solved with a pad having the features of claim 1 and with a bandage having the features of claim 14. Further developments and advantageous embodiments of the inventions are described in the respective subordinate claims.

[0006] The pad, designed to be incorporated into a bandage and intended to support body tissue, and featuring ventilation channels on the side facing the body, is characterized according to the invention in that the pad has external channels on the side facing away from the body. This combination of internal and external ventilation channels reduces the thickness of the pad in certain areas, resulting in particularly high elasticity and stretchability. The internal ventilation channels also serve to wick away moisture, especially perspiration, thus ensuring a high level of wearing comfort.

[0007] The stretch properties of the bandage are further improved by the fact that the outer channels are aligned at approximately 90° to the circumferential direction of the bandage.

[0008] In a preferred embodiment of the invention, the ventilation channels and the outer channels are arranged parallel to each other. This arrangement achieves particularly good extensibility. Furthermore, it is preferred that the ventilation channels and the outer channels are arranged alternately. This can also be described as an accordion structure. With such an arrangement, the overall thickness of the pad remains comparatively thin, and the ventilation channels alternate between the inner and outer channels. In particular, this arrangement allows for extensibility at right angles to the orientation of the outer channels.

[0009] The ventilation ducts and the external ducts are preferably of approximately the same width. This ensures that the effectiveness of the previously described accordion structure is particularly well achieved.

[0010] Furthermore, it is preferred that openings are present in the pad. These are preferably located in the ventilation channels, allowing fluid to drain from the body side to the outside. The ventilation channels preferably comprise a first group of parallel ventilation channels and a second group of ventilation channels oriented perpendicular to the first group. In alternative embodiments, it may also be advantageous for the first group of ventilation channels and the second group of ventilation channels to intersect at an angle of ±45° or ±60°.

[0011] In the intersection areas of the first group of ventilation ducts and the second group of ventilation ducts, openings are preferably arranged through which liquid can escape to the outside via evaporation. In a particularly preferred embodiment of the invention, the openings terminate on the outside between the outer ducts. On the outside, wall sections are present between the outer ducts into which the ventilation ducts terminate.

[0012] The geometric design is preferably such that the openings form a grid consisting of the vertices of squares. Such a uniform distribution ensures reliable drainage of the liquid.

[0013] Preferably, the pad is made of an elastomer, especially silicone. Silicone rubber, TPU, or TPE material can be used.

[0014] In a specific embodiment, the pad is ring-shaped. Such a pad is particularly suitable for use in the area of ​​the knee and the patellar tendon.

[0015] In another embodiment, the pad is elongated and has an annular shape at one end, or a circular or oval recess at one end. Such a pad is intended for use in the elbow region.

[0016] In another preferred embodiment, the pad is J-shaped. Such a pad is particularly suitable for use in the ankle area.

[0017] Another aspect of the invention consists in providing a bandage, wherein the bandage, according to the invention, comprises a pad as described above. The pad is incorporated into a surrounding textile. In this way, a bandage according to the invention is provided.

[0018] The invention is illustrated in the following drawing. Further inventive features may emerge from the embodiments of the invention shown and described therein. Figure 1: A knee pad with Figure 1a , a body-side view; Figure 1b a view turned away from the body and Figure 1c a sectional perspective side view; Figure 2: A flat pelotte with Figure 2a , a body-side view and Figure 2b a view turned away from the body; Figure 3: Cross-section through the upper part of a patellar pad with Figure 3a an unstretched patellar pad and Figure 3b a stretched patellar pad; Figure 4: A "J"-shaped pad for use in the ankle area with Figure 4a , a view of the pad that is oriented towards the body; Figure 4b a view of the side of the pad that is facing away from the body and Figure 4ca sectional perspective view of the pelotte; and Figure 5: Figure 5a , a perspective cutaway view of an elongated pelotte to illustrate the accordion structure, which is ring-shaped in one end area and Figure 5b A perspective cutaway view through the ventilation cross-channel with the ventilation holes of an elongated pad.

[0019] In Figure 1 A pad 1 is shown, which here is designed as a ring-shaped pad intended for support in the knee area and the patellar tendon. Figure 1aThe inner side 2, i.e., the side of the pad 1 facing the body, is visible. Ventilation channels are formed on the inner side 2, with a first group of ventilation channels 3 and a second group of ventilation channels 4 running at right angles to them, so that square support bodies 10 are formed between each group of ventilation channels. Openings 6 are formed in the intersection areas 5 of the first group of ventilation channels 3 and the second group of ventilation channels 4. These openings are designed and configured to transport liquid, in particular perspiration, from the inside to the outside via evaporation.

[0020] In Figure 1b Is the pad 1 made of Figure 1aThe other side, namely the outer surface 7, is shown. This outer surface 7 is designed and intended to be supported on the side facing away from the body. External channels 8 are formed in the outer surface 7. These are aligned parallel to each other and, as a result, parallel to the first group of ventilation channels 3 on the inner surface 2 of the pad 1. Wall sections 9 are located between the external channels 8. The openings 6, which extend from the inner surface 2 to the outer surface 7, open into these wall sections 9.

[0021] In Figure 1cThe pelotte 1 is shown in a sectional perspective view. It is particularly evident that the ventilation channels 3 of the first group run parallel to and offset from the outer channels 8 of the pelotte 1 on the inner surface 2. This results in the accordion-like structure, which achieves particularly high elasticity. The square support bodies 10 are also visible here.

[0022] In Figure 2A flat pad 1 is shown, with the inner surface 2, i.e., the side of the pad facing the body, shown in 2a. Ventilation channels 3 are provided on the inner surface 2, intersecting at angles of 90° and 45°. Openings 6 are provided in the intersection areas 5. The ventilation channels can also be described as two groups. A first group of ventilation channels 3 runs parallel to each other. A second group of ventilation channels 4 also runs parallel to each other. The two groups of ventilation channels intersect at an angle of 45°, forming triangles with one 90° angle and two 45° angles.

[0023] On the in the Figure 2bThe reverse side of the pad is shown as the outer surface 7. This outer surface 7 is designed and intended to be worn on the side facing away from the body. External channels 8 are formed in the outer surface 7. These are aligned parallel to the first group of ventilation channels 3 on the inner surface 2 of the pad 1. Wall sections 9 are located between the external channels 8. The openings 6, which extend from the inner surface 2 to the outer surface 7, open into these wall sections 9.

[0024] In Figure 3 is another cross-section through a patellar pad according to Figure 1The upper side is the inner side 2, which is worn against the body. The lower side is the outer side 7, which is worn on the side facing away from the body. The ventilation channels 3 are visible on the inner side 2, and the outer channels 8 are visible on the outer side 7. The channels create an accordion-like structure, allowing the entire pad to be stretched. This is shown in the Figures 3a and 3b especially clearly.

[0025] In Figure 4 with the Figures 4a, 4b and 4c A "J"-shaped pad is shown, which serves to support the ankle. In Figure 4a The side shown is the one that is oriented towards the body. Figure 4b The side facing away from the body is shown. Figure 5a A sectional perspective view is shown. Figure 5b is a cut comparable to Figure 5a To illustrate the accordion structure. Comparable to the pelotte according to Figure 1 is in the Figure 4aA first group of ventilation ducts 3 and a second group of ventilation ducts 4 are formed, running at right angles to each other and meeting at intersections 5. The intersections 5 form a square grid. Openings 6, through which liquid can flow from the inside to the outside, are also provided in each intersection 5. The system components 10 are formed between these intersections 5.

[0026] In Figure 4b The outer surface 7 of the pelotte 1 is shown. The outer channels 8 are present here, with wall sections 9 between the outer channels 8. The openings 6 open into the wall sections 9. In the perspective view according to Figure 4cThe inner surface 2 is shown at the top and the outer surface 7 at the bottom. On the inner surface 2, the grid of ventilation ducts 3 of the first group and ventilation ducts 4 of the second group is visible, between which the system components 10 are formed. On the outer surface 7, external ducts 8 are present, which are parallel to and offset from the first group of ventilation ducts 3. This results in the accordion structure, which achieves particularly high elasticity.

[0027] In Figure 5Figure 1 shows a sectional perspective view of a pad 1 designed for treating tendons in the elbow region. This pad is elongated and has an approximately circular or slightly oval recess at one end. On its inner surface 2, the pad also features a first group of ventilation channels 3 extending from top to bottom in the figure and a second group of ventilation channels 4 extending from right to left. The support elements 10 are located between the first group of ventilation channels 3 and the second group of ventilation channels 4. Openings 6 are provided at the intersections 5. On the outer surface 7 of the pad 1, external channels 8 are provided, running parallel to and alternating with the ventilation channels 3 of the first group. This arrangement provides lateral elasticity to the pad 1.
