ABSTRACT:
The invention relates to a ready-made bandage with a selfadhesive coating on one side, for restricting stretching or bending of the metacarpophalangeal joint and of the wrist.
BACKGROUND OF THE INVENTION
The functional dressing technique called taping is a treatment method for prevention and therapy of injuries, diseases and lesions of the locomotor apparatus. The aim of taping is to purposefully simulate the capsular ligament structures and in so doing to achieve selective support and stabilizing.
The actual tape dressing is applied in strips made up of preferably non-elastic self-adhesive tapes, so-called reins, or in conjunction with lowstretch elastic self-adhesive tapes. It protects, supports and relieves vulnerable, injured or damaged parts of a functional unit. It permits selective loading within the pain-free area of movement, but prevents extreme or painful movements.
However, the application of such dressings requires expert skill and experience and for this reason cannot generally be done by lay persons with no taping experience.
As regards the metacarpophalangeal joint, which is often exposed to very considerable mechanical stress, especially when performing sporting activities, which stress can lead to distortions and contusions, but also to overload irritation of the capsule, the expert nevertheless requires a ready-made bandage which is of a simple construction and at the same time can be applied without problems, and which, especially in the case of minor injuries, has a positive influence on the healing process.
The same also applies to the wrist, so that the demands made of the ready-made bandage are the same as those in the case of the metacarpophalangeal joint.
However, such a ready-made bandage should also be able to be applied by the lay person, affording the after an economic and less time-intensive aid by means of the ready-made bandage.
The object of the invention was therefore to make available a ready-made bandage which, because of its construction, its material and its properties, is suitable for supporting the healing process in injuries of the metacarpophalangeal joint or wrist by restricting the stretching or bending capacity, and which in addition can be easily applied by the user.
SUMMARY OF THE INVENTION
This object is achieved by means of a ready-made bandage having a self-adhesive coating on at least one side, for restricting stretching or bending of the metacarpophalangeal joint and/or of the wrist, comprising an oblong strip (
1
) having a head area (
13
), a bottom area (
12
) and two longitudinal sides, a short rein (
41
,
42
) arranged on at least one of the two longitudinal sides, enclosing an angle of between 30° and 150° with the oblong strip, which is applied to the finger in question.
Furthermore, at the bottom area of the oblong strip, a first rein can be arranged on at least one of the two longitudinal sides, which first rein encloses an angle of between 30° and 150° with the oblong strip and is applied in a circle round the lower arm proximal to the wrist.
DETAILED DESCRIPTION
Advantageously, the first rein and/or the short rein is arranged at an angle of 90° to the oblong strip. This also applies in the case where, instead of one first rein, two or more first reins are provided, or where, instead of one short rein, two or more short reins are provided.
Furthermore, the oblong strip can narrow starting from the bottom area towards the head area.
In a first preferred embodiment of the ready-made bandage according to the invention which is used for restricting bending of the metacarpophalangeal joint and of the wrist, and in which a first rein and a short rein are fitted in each case on the oblong strip on each of the two longitudinal sides, the oblong strip is about 12 cm to 30 cm long, and, at the transverse side in the bottom area, is 3 cm to 7 cm wide, and, at the transverse side in the head area, is 1 cm to 3 cm wide, the first reins are each about 5 cm to 30 cm long and 2 cm to 6 cm wide, and the short reins are each about 3 cm to 6 cm long and 1 cm to 3 cm wide.
The dimensions of the ready-made bandage are of course adapted to the size of the hand on which the ready-made bandage is being applied. For the average adult hand, the individual parts of the ready-made bandage have the following sizes:
The oblong strip is about 20 cm long, 6 cm wide on the transverse side in the bottom area, and 2 cm wide on the transverse side at the head area.
The first reins are 22 cm long and 5 cm wide.
The short reins are 5 cm long and 2 cm wide.
All the strips and reins can additionally have rounded corners in order to reduce the risk of unintentional detachment of the adhered ready-made bandage.
At the middle area of the oblong strip, a second rein can be arranged likewise on at least one of the two longitudinal sides, which second rein encloses an angle of between 30° and 150° with the oblong strip and is applied on the palmar surface of the hand.
The first rein, the second rein and/or the short rein are advantageously arranged at an angle of 90° to the oblong strip. This also applies in the case where, instead of a first or second rein, two or more reins are in each case provided, or where, instead of one short rein, two short reins are provided.
Furthermore, the oblong strip can narrow starting from the middle area towards the head area.
In a second preferred embodiment of the ready-made bandage according to the invention which is used for restricting stretching of the metacarpophalangeal joint and of the wrist, and in which a first rein, a second rein and a short rein are in each case fitted on the oblong strip on each of the two longitudinal sides, the oblong strip is about 12 cm to 30 cm long, and, at the transverse side in the bottom area, is 3 cm to 6 cm wide, and, at the transverse side in the head area, is 1 cm to 3 cm wide, the narrowing of the oblong strip starting after approximately 6 cm to 22 cm measured from the transverse side in the bottom area, the first reins are each about 5 cm to 30 cm long and 2 cm to 6 cm wide, the second reins are each about 5 to 30 cm long and 2 cm to 6 cm wide, and the short reins are each about 3 cm to 6 cm long and 1 cm to 3 cm wide.
The dimensions of the ready-made bandage are of course adapted to the size of the hand on which the ready-made bandage is being applied. For the average adult hand, the individual parts of the ready-made bandage have the following sizes:
The oblong strip is about 18 cm long, 6 cm wide on the transverse side in the bottom area, and 2 cm wide on the transverse side at the head area, the narrowing of the oblong strip starting after 12 cm measured from the transverse side in the bottom area.
The first reins are 22 cm long and 5 cm wide.
The second reins are 22 cm long and 3.75 cm wide.
The short reins are 4 cm long and 2 cm wide.
All the strips and reins can additionally have rounded corners in order to reduce the risk of unintentional detachment of the adhered ready-made bandage.
It has proven particularly advantageous for cuttings or recesses to be provided at the points where the oblong strip, the first reins, the second reins and/or the short reins meet. These cuttings prevent the ready-made bandage from tearing at the points which have the highest loading, particularly during application. Alternatively, the recesses increase the flexibility of the ready-made bandage, so that alternatively application is made easier.
Again preferably, the self-adhesive ready-made bandage according to the invention is of a non-elastic woven fabric or knitted fabric. Elastic or plastic components in the longitudinal direction or transverse direction of the support material can sometimes also advantageously influence user comfort. Furthermore, nonwovens or foams or paper can also be used if these have sufficient strength.
The support material can preferably be of cotton and can additionally have a maximum tensile force of not less than 50 N/cm and a maximum tensile force extension of less than 20%.
On the side applied to the skin, the ready-made bandage is coated with one of the known
