Description

TITLE

COMPRESSION BANDAGE

DESCRIPTION

Technical area

The present invention relates to a compression bandage, such as for ankle-joints, knees and thighs, for quickly taking good care of spraining, leading-strings injuries and interior extravasations of blood.

The object of the present invention is to achieve a pressure or compression bandage for quickly preventing substantial extravasations of blood in injured joints and extremities.

The background of the invention

Originally, at sprainings, it was considered sufficient to put a supporting bandage for a dilated ligament and surrounding musculature, to facilitate keeping the joint and increase the stability. Such bandages were of band type and were elastic. However, it was shown that any real mitigation and prevention of pain and additional extravasation of blood in the joint injured did not occur, but in principle, it was possible to consider the bandage as ineffective.

Later experiences have shown that quick treatment of sprained joints and other injuries leading to extravasation of blood by means of establishing a pressure bandage, leads to a very rapid healing and rehabilitation. Thereby it is very important that a tightened bandage is very firmly put within the course of some minute to give an effect in this aspect. Hereby the problem is to apply the correct pressure over a surface/area being sufficiently large enough on the joint to be treated. If bandage of band type is used, a particular education is required to be able to correctly put a bandage and accordingly obtain the right effect. Thereby the band should also be non-elastic. If the bandage is incorrectly applied, the consequences may be huge with a very extended rehabilitation time. It is also known heating bandages for knee-joints comprising a wrapping adjusted for the knee-joint comprising a foam plastic/foam rubber laminate for achieving heat or maintain heat, which facilitates softening of the cartilage of the knee-joint, which is substantial for an adequate motion of the joint.

US-A-5,743,866 describes a bandage for immobilization and support of the members injured (an orthosis), which in no way has to do with the bleeding compression of muscles and ligament. A knee orthosis should often be used for support of tissues and for stiffening of a joint and should thereby also admit flexure of the orthosis itself, for instance during sports exercising, training and walking. The primary task of the drawstrings in an orthosis is to hold the orthosis close next to the leg for best effect in the control of the motion in the knee-joint as well as, in some cases, limit the over- mobility in the knee joint. To admit flexure implies that the orthosis is elastic. Thus the purpose is not to obtain a pressure preventing a bleeding.

The bandage according to US-A-5,743,866 is described in the text in a number of places as being tubular bandage, which also indicates the big difference in comparison to the present pressure bandage. Tubular supports and immobilization bandages (orthoses) have been present on the market since the 1950s. The bandage according to the U.S. Patent Publication shows moreover short straining belts, which excludes the possibility to obtain a pressure for treatment of a bleeding injury.

The bandage according to US-A-5,743,866 is applied over the foot and is drawn up over the knee to be treated. At this type of application, there is a risk that an injury in the knee should grow worse with increased bleeding, as a consequence of the movement at the threading-on of the orthosis/bandage, in the case that it is used for treatment of a bleeding injury which is the object of the present bandage. This shows, leaving no room for doubt, that the bandage according to this U.S. Patent Publication is not an acute bandage, but in short an orthosis.

The problem today is to obtain correct bandaging at joint injuries and the like, where an interior blood shedding occurs, such as for instance at so-called blood clot after hemorrhage in thigh.

Description of the present invention

It has now surprisingly been shown possible to solve this problem by means of the present invention, which is characterized in that the bandage is composed of a preformed, non-elastic, casing possible to open, which casing is provided with non- elastic variable sealing devices.

Further characteristics are evident from the accompanying claims.

By means of the present invention it is obtained, that with a few preformed bandages, it is possible to treat the most occurring joint injuries and the like, within a very short time without any particular previous education. It is important that the requirement of education is small since such injuries, often sports injuries, may occur in all possible contexts, such as everything from different boll games in the youth series to matches in the competitive sports series, where in the former case, there is often a very limited education level concerning sports injuries. Further the individual sports practicer may easily apply the bandage. Hereby, sports practicers should be placed on an equal foot with all others which may get into this type of injuries, such as people moving in beaten terrain, such as hunters and forestry people, farmers and others.

A pressure bandage shall not, to be effective, admit such flexures as normally appear for instance in a knee-joint, and the present completely non-elastic bandage can therefore not be found in the cited patent publication. By being non-elastic, it can neither be used as an orthosis.

The present bandage is basically non-tubular, but is a pressure plate with non-elastic belts, which are tightened for exerting a pressure.

The present bandage is brought on the part injured (thigh, knee or foot) and is tightened, whereby a pressure over the area injured is immediately obtained, without any risk for that the part of the body injured being exposed to movement. Use of the present pressure bandage has also proven that a massive so-called blood clot after hemorrhage in thigh, i.e. a major blood shedding in the thigh muscle after for instance knee collision during a football game, can heal-out in two to three days.

The present bandage may also be completed with a separate pressure plate/compression plate which means that a specific pressure is exercised on the area injured.

The bandage according to the present invention will be described with reference to some preferred embodiments shown thereof in the enclosed drawing, however without being limited to this. In the drawing

Fig. 1 shows an ankle-joint bandage in perspective;

Fig. 2 shows a knee-joint bandage in perspective;

Fig. 3 shows a thigh bandage in perspective; and

Fig. 4 shows a cut through a bandage according to Figs. 1-3

With reference to fig.1 , 1 denotes a formed casing which has the form of a foot, and which is manufactured of a flexible material, such as so-called beaver nylon, being a strong non-elastic woven material of polymer thread. At the inside of the casing 1 a number of loops 2 are arranged in their respective attachments 3, which attachments 3 is fixedly sown to the casing 1 , every second time on one side and every second time on the other side so that every other loop is on the right and every other loop is on the left handside. Bands 4 are arranged across the casing 1 in a level with the respective loop 2, which bands 4 are also manufactured of a non-elastic material and which bands partly show a part 5 with a structure of velcro closing, partly a part 6 with adherent weave for velcro closing. The respective band 4 is appropriately provided with numbers, which state the order in which they should be tighten for obtaining best possible pressure action on a foot introduced in the casing 1. The casing 1 may be completely opened by means of releasing the all bands, whereby a foot injured may easily be put in the casing 1, after which the bands 4 are introduced in their respective loops 2, and are tightened to a maximum tension. For increasing the contact of the bandage, a support plate in form of a foam rubber/foam plastic disc 7 may be introduced in the bandage, as appears in fιg.4, whereby the casing 1 is formed double for admitting introduction between two layers in the casing 1. By the design shown with band-loop every second time on one side and every second time on the other side, a bandage is not bound for a right or a left foot, respectively.

With reference to fig. 2 a casing 1 is shown again having a number of transverse bands 4 provided with velcro closings 5 and adherent weave 6 for velcro closings, respectively, and arranged to be thread through the loops 2, whereby the loops 2 are attached in the attachments 3. For improving the comfort at use the casing 1 is provided with a through-going hole 8 for a kneecap. Hereby the bands 4 are adjusted to the hole opening so that a overlap of this does not occur.

With reference to fig.3 another casing 1 is shown having a number of transverse bands 4 provided with velcro closings 5 and adherent weave 6 for velcro closings, respectively, and arranged to be thread through the loops 2, whereby the loops 2 are attached in the attachments 3. This bandage, being intended to limit a bleeding in a thigh, is thereby not provided with a through-going hole. The casing 1 is also somewhat longer in reality than the casing 1 intended for the knee-joint.

This bandage may also be designed for arm-joints and arm musculature in the same way, whereby the important thing is still that the bandage is non-elastic and that it is simple to be brought in place and tightened, even without any help.
