Description

Compression device comprising a compression band and a holding device

The present invention relates to a compression device of the type comprising at least one compression band extending in a direction of elongation and at least one holding device comprising at least one holding strip extending in a direction of extension, said compression band being extensible at least in the direction of elongation and the retaining strip being substantially inextensible in the direction of extension, the compression band forming a bandage comprising turns when it is wound in the direction of elongation around a part of a patient's limb, the support band comprising at least one reversible fixing device on the compression band.

The invention also relates to a method of placing such a compression device around a part of a patient's limb.

It is known to apply a specific pressure on a limb or on part of a limb of a patient, for example in the context of the treatment or prevention of venous pathologies.

To apply pressure, compression items, such as stockings, tights, socks, compression sleeves or the like, are generally used. Such items are sized to apply the desired pressure and a particular item always applies the same compressive pressure. The articles are therefore offered in different sizes adapted to apply different compression pressures. The choice of a type of compression article and its size is made according to the part of the limb on which the treatment must be applied and according to the desired pressure.

However, the use of such items is not always possible, for example when a patient cannot put on the compression item. This is particularly the case when a patient suffers from an acute sprain, an active venous ulcer, or other symptoms that make donning or wearing a compression garment too painful.

In such a scenario, it is known to use one or more compression bands instead of a compression article to put on. Such a compression bandage is applied to the part of the limb to be treated by being wound around it so as to form a bandage comprising partially overlapping turns.

The installation and maintenance of such a compression bandage, however, is complicated because the band must be rolled up while being stretched to apply the desired pressure and this stretching must be maintained while the band is rolled up. Once the bandage is placed, it should be attached to the limb to hold it in place and apply the compression treatment.

In addition, for the compression treatment to be effective, the compression band must be held in place for a long period of time without the turns sliding on each other and/or on the limb, which would cause a release of pressure exerted on the limb part. Such slippage also requires the bandage to be redone regularly, which results in a significant workload for health personnel.

In order to fix the compression band, it is for example known to use a fastening clip to fix the compression band on itself at one end thereof, but such fixing is not likely to prevent slippage of the band along the limb, particularly after the band has been worn for a period of time. Also, it is common for these staples to injure the patient or the hands of the person positioning them.

One of the aims of the invention is to overcome these drawbacks by proposing a compression device comprising at least one compression band held effectively on a part of the limb around which the band is wound and which can be worn for a long time. period without significant slippage of the turns of the belt.

For this purpose, the invention relates to a compression device of the aforementioned type, in which the compression band and the holding device are formed by separate parts, said holding device being wound in the direction of extension on the band of compression by being fixed reversibly on at least one turn of the bandage by making at least one complete turn of said turn in the direction of elongation to form a strapping around said turn and the limb part when the compression band is wrapped around said limb part.

By forming a closed and fixed strapping around a turn of the bandage using a holding device comprising at least one substantially inextensible strip, effective holding of the bandage is ensured on the part of the limb to which the bandage is applied. , in particular by preventing slippage of the turn around which the strapping is carried out, which also leads to blocking of the other turns of the bandage. Thus, the bandage can be worn for long periods without the compression exerted being modified, even when the patient wearing the bandage moves. Additionally, because the strapping is applied to the bandage, the strap material is not applied to the patient's skin and does not cause discomfort when the patient wears the bandage.

The compression device according to the invention may further comprise one or more of the following characteristics, considered alone or in any technically conceivable combination:

- the support strip comprises an internal face, applied to the turn of the bandage, and an external face, opposite the internal face, the reversible fixing device of the support strip extending on the internal face;

- the retaining strip comprises a complementary fixing device extending on the external face, one end of the retaining strip being applied to the opposite end of the retaining strip so that an internal face portion is applied to part of the external face and that said complementary fixing device cooperates with the reversible fixing device in order to fix the retaining strip on itself or on another retaining strip of the retaining device when the retaining device is wound on the turn of the bandage;

- the compression band comprises an internal face, applied to the patient's skin when the compression band forms a bandage around a part of the patient's limb, and an external face, opposite the internal face, a complementary fixing device extending on the external face and cooperating with the reversible fixing device of the retaining strip so as to directly fix the retaining strip on the turn of the bandage when the retaining device is wound on the turn of the bandage;

- the reversible fixing device comprises hooks and the complementary fixing device comprises loops, the hooks being able to hook with the loops;

- the bandage extends between two end turns, the holding device being wound on one of said end turns;

- the retaining strip has a length, measured in the direction of extension, substantially between 30 cm and 60 cm and a width, measured in a direction substantially perpendicular to the direction of extension, substantially greater than or equal to 10 mm and less than or equal to the width of the compression band, measured in a direction substantially perpendicular to the direction of elongation;

- the compression bandage is a dry bandage.

According to another aspect, the invention relates to a method of placing a compression device as described above on a part of a patient's limb, the method comprising the following steps:

- wrap the compression band around the part of the patient's limb in the direction of elongation so as to form a bandage comprising turns extending around the part of the patient's limb,

- winding the holding device around at least one turn of the bandage, said holding device making at least one complete turn of said turn in the direction of elongation and forming a strapping around said turn, said holding device being fixed reversibly on the bandage.

The method may include the following characteristic when the patient's limb is one of said patient's legs, the holding device is wound and fixed around an upper end turn extending around an upper part of the calf at the vicinity of the knee of said leg.

Other aspects and advantages of the invention will appear on reading the description which follows, given by way of example and made with reference to the appended drawings, in which:

- there is a schematic perspective representation of a compression band of a compression device according to the invention wrapped around a part of a patient's limb to form a bandage,

- there is a schematic perspective representation of a retaining strip closed on itself to form a strapping,

- there is a schematic perspective representation of the compression device according to the invention applied to a part of a patient's limb, and

- there is a schematic side view showing a location of the support band on a patient's leg.

With reference to Figs 1 to 3, a compression device is described comprising at least one compression band 1 and a holding device comprising at least one holding strip 2. Such a compression device is intended to be applied to a part of limb 4 of a patient, such as the lower part of a leg going for example from the top of the calf to the foot of the patient, as shown in Figs. 1 and 3.

The compression band 1 extends mainly in an elongation direction L and comprises an internal face and an external face 6, opposite the internal face. The length of the compression band 1 corresponds to the dimension of the compression band in the direction of elongation L and the width of the band corresponds to the dimension of the band in a direction perpendicular to the direction of elongation L, called transverse direction T.

The compression band is wrapped around the limb part 4 to be treated in its direction of elongation so as to cover the limb part to be treated.

When the compression band is wrapped around a limb part 4, the internal face is applied to the patient's skin and the external face 6 is turned towards the outside of the limb part 4. By convention, the terms " under”, “on”, “below”, “above”, etc. are defined in relation to the direction going from the internal face to the external face 6, corresponding to the thickness of the compression band 1.

As shown on the , when the compression band 1 is wound on the limb part 4, the compression band 1 partially overlaps, that is to say that part of the internal face of an upper turn is applied to a part of the external face 6 of a lower turn in a covering zone, a turn corresponding to one turn of the band around the member part 4. The covering zone extends for example over substantially half the width of the compression band. Alternatively, the covering can be done over less than half of the width of the strip or over half, for example over two thirds of the width of the strip.

When the compression band 1 is wound on the limb part 4, it forms a bandage comprising several turns, including two end turns between which the bandage extends. The end turns are spaced apart from each other according to the length of the member part. Thus, in the case of the lower part of a leg, one of the end turns, called lower end turn 8 extends at the level of the foot, and the other end turn, called d turn The upper end 10 extends over the top of the calf near the knee. When installing the compression band 1, a healthcare professional begins by forming the lower end turn 8 and rolling the compression band up to the upper end turn 10.

The compression band 1 is extensible at least in the direction of elongation L. In other words, the compression band 1 can be stretched in the direction of elongation L. The compression band 1 has for example an elongation comprised between 10% and 180% depending on the direction of elongation. As is known per se, stretching the compression band in the direction of elongation L makes it possible to adjust the pressure exerted by the compression band on the limb part 4 around which the compression band is wound. According to a particular embodiment, the compression band is also elastic in the direction of elongation, so that it returns to its initial length when stretching ceases to be applied to the compression band.

According to one embodiment, the compression band 1 is also extensible in the transverse direction T. We then speak of a bi-extensible compression band. The extensibility according to the transverse direction T is for example between 0% and 100%, 0% corresponding to a compression band 1 extensible only in the direction of elongation L. For the extensibility according to the direction of elongation and according to the transverse direction, the elongation is measured according to the specifications of the NF EN ISO 20932 standard of February ¹ , 2020. As known in itself, the extensibility in the transverse direction T makes it easier to install the compression band, because it -this naturally adapts to the morphology of the member part 4 around which the strip is wound, and reduces the risk of creases forming in the strip during installation.

During the installation, the healthcare professional maintains a certain tension in the compression band according to the direction of elongation L in order to apply the desired pressure on the limb part 4. In addition, during the installation, the compression strip is for example wound so that the turns extending in the direction of elongation L form an angle, greater than 0° and less than or equal to 90°, with respect to a direction substantially perpendicular to the length of the member part 4, this direction corresponding to the width of the member part. The angle is for example more particularly between 0° and 45°, preferably between 0° and 20°.

The compression band is for example a so-called “dry” band, that is to say a band without adhesive to attach to itself and/or to the patient’s skin. It is in fact with dry belts that the problem of slipping of the turns of the tire mainly arises.

The holding device is formed by one or more separate parts of the compression band 1. Thus, when the holding device only comprises a holding strip 2, the holding strip 2 and the compression band 1 are not permanently attached to each other. In other words, when the retaining strip is fixed on the compression band 1, as will be described later, the retaining strip is attached to the compression band 1, the fixing is reversible and the retaining strip can be completely separated from the compression band when the binding is undone. When the support device comprises several support strips, as will be described later, the compression strip and each support strip are formed by separate parts.

When several retaining strips 2 are provided, the different retaining strips are substantially identical to each other. A single retaining strip 2 will now be described.

The retaining strip 2 extends in a direction of extension and has a length, measured in this direction of extension, sufficient for the retaining strip 2 to make at least one complete turn of a turn of the bandage when the strip support 2 is fixed on the bandage by being wrapped around the bandage in the direction of extension. Thus, the retaining strip 2 has for example a length, measured in the direction of extension, substantially between 30 cm and 60 cm. Thus, when the circumference of the part of the limb around which the support device is applied is greater than 60 cm, the support device comprises several support strips, as will be described in more detail later. Furthermore, the retaining strip 2 has for example a width, measured in a direction substantially perpendicular to the direction of extension, less than or equal to the width of the compression strip 1. Thus, the retaining strip 2 has for example a width, measured in a direction perpendicular to the direction of extension, substantially greater than or equal to 10mm and less than or equal to the width of the compression band 1.

The retaining strip 2 is substantially inextensible according to the direction of extension. By inextensible, we mean that the retaining strip 2 is not, or only slightly, extensible depending on the direction of extension and has, for example, an elongation of between 0% and 60%.

As more particularly visible on the , the retaining strip 2 has an internal face 12 and an external face 14. When the retaining device is wound on the bandage, as will be described in more detail later, the internal face 12 of the retaining strip 2 is applied to the compression band 1 and the external face 14 faces outwards from the limb part 4.

As indicated previously, the holding device is arranged to be fixed reversibly on the compression band 1. More particularly, the holding device is wound on the compression bandage 1 in the direction of extension so as to make at least a complete turn of at least one turn of the bandage, as shown in the .

More particularly, when the holding device comprises a single holding strip, the holding strip 2 is for example arranged to make more than one complete turn of the turn and to be reversibly fixed on itself at its ends 16 , as shown on the . When several retaining strips 2 are necessary, these are reversibly fixed to each other at their ends to make one or more than one complete turn of the turn.

For this purpose, the or each retaining strip 2 comprises, on the internal face 12, a fixing device 18 and on its external face 14, a complementary fixing device 20, able to cooperate with the fixing device 18 to fix in a manner reversible the retaining strip 2 on itself. Thus, when the retaining strip 2 is wound on a turn of the bandage, the internal face 12 of one of its ends 16 is applied to the external face 14 of the other end 16 so as to apply the fixing device 18 on the complementary fixing device 20 and to make these cooperate together to fix the retaining strip 2 on itself and thus ensure the fixing of the retaining strip 2 on the bandage.

According to one embodiment, the external face 6 of the compression band 1 also comprises a complementary fixing device (not shown) so that the fixing device 18 on the internal face 12 of the retaining strip(s) 2 cooperates with the complementary fixing device on the external face 6 of the compression band when the holding device surrounds a turn of the bandage in order to ensure direct fixing between the holding strip(s) 2 and the compression band 1. Thus, the or the retaining strips 2 are fixed on the bandage as the retaining strip(s) 2 are applied to the bandage to go around it. In addition, involuntary separation between the retaining strip(s) 2 and the bandage is prevented. It is understood that the complementary fixing device provided on the external face 6 of the compression band is not necessarily identical to the complementary fixing device 20 provided on the external face 14 of the retaining strip 2. Thus, the device of complementary fixation on the external face 6 of the compression band is for example obtained without particular treatment of the external face 6 of the compression band, which can naturally be adapted to cooperate with the fixing device 18 of the internal face of the or support strips 2.

According to a particular embodiment, the retaining strip 2 makes a complete turn of a turn of the bandage and is only fixed on the compression band 1 by the cooperation of the fixing device 18 and the complementary fixing device on the external face 6 of the compression band 1. In other words, according to this embodiment, the retaining strip 2 is not fixed on itself and makes exactly a complete turn of the bandage, the ends 16 of the retaining strip 2 being placed end to end to form the strapping. According to this embodiment and although this is not preferred, the external face 14 of the retaining strip 2 can then be devoid of a complementary fixing device.

The retaining strip 2 can therefore adapt to several diameters of the limb part 4, by being fixed on itself, and possibly on the bandage, when the circumference of the limb part 4 is less than the length of the support strip 2, by being fixed only on the compression band 1 when the circumference of the limb part 4 is substantially equal to the length of the support strip 2 or by being fixed to another support strip 2 when the circumference of the limb part 4 is greater than the length of a retaining strip 2. It is understood that more than two retaining strips 2 can be provided if necessary.

According to the embodiment shown on the , the fixing device 18 is formed by hooks 22 extending projecting from the internal face 12 of the retaining strip 2 and the complementary fixing device 20 is formed by loops 24 extending projecting from the external face 14 of the retaining strip 2 and/or the external face 6 of the compression strip 1. As indicated previously, the loops provided on the external face 14 of the retaining strip 2 do not necessarily have the same dimensions as the loops formed on the external face 6 of the compression band 1. The hooks 22 are capable of hooking into the loops 24 to ensure reversible fixing between the fixing device 18 and the complementary fixing device 20. Advantageously, the hooks 22 extend over the entire internal face 12 of the retaining strip 2 and the loops 24 extend over the entire external face 14 of the retaining strip 2 and/or the external face 6 of the compression band 1. Thus, any part of the internal face 12 of the support strip 2 can be fixed to any part of the external face 14 of the support strip 2 and/or another support strip 2 and/or any part of the external face 6 of the compression strip 1. It is understood that the fixing device 18 could be of another nature, such as an adhesive adapted to adhere reversibly with the external face 14 of the support strip 2 and/or another support strip and/or with the external face 6 of the compression strip 1.

The strapping of a turn of the bandage by the holding device is such that the internal face 12 of the holding strip(s) 2 extends entirely opposite the bandage, that is to say that the holding strip(s) support 2 are only applied to the external face 6 of the compression band 1 and/or to the support strip 2 and not to the patient's skin. Thus, the strapping does not degrade the comfort of wearing the bandage.

In addition, the strapping is adjusted around the turn of the bandage, that is to say the holding device is wrapped around the bandage without modifying the pressure exerted by the compression band 1 on the limb part 4 Such an adjustment makes it possible to slightly increase the interface pressure between the turns and therefore to increase the coefficient of friction of the turn covered by the strapping on the previous turn partly covered by this turn. Increasing the coefficient of friction makes it possible to reduce, or even eliminate, the sliding of the covered turn on the previous turn, and consequently the sliding of the previous turn on the turn it covers, etc. The strapping also has the effect of dimensionally freezing the length of the compression band 1 on the last turn, which cannot then relax, lose compression force and slide.

The holding device is advantageously positioned on the bandage in the vicinity of one of the end turns of the bandage, more particularly the upper end turn 10 in the case of a bandage applied to the lower part of a leg , as shown in Figs. 3 and 4. According to one embodiment, the holding device is applied to and surrounds the upper end turn 10 of the bandage. Indeed, in the case of a bandage applied to the lower part of a leg, it has been observed that the phenomenon of sliding of the turns is more pronounced towards the end of the bandage while the beginning of the bandage is practically not subject to such a shift. It was also found that a single strapping in the vicinity of the upper end turn 10 made it possible to eliminate this phenomenon for a long period of time, in particular more than 24 hours. As shown on the , the strapping is for example provided around a turn extending around an upper part of the calf near the knee of the leg. More particularly, the strapping is for example provided just above the part of the calf having the largest diameter, that is to say above the curve of the calf, which prevents the strapping from passing the curve of the calf by sliding by gravity according to the length of the leg. More particularly, the strapping is for example placed between the largest circumference of the calf and the circumference of the calf where the bandage stops.

The retaining strip(s) 2 are for example applied substantially along the axis of the limb part 4 on which the bandage is applied. Thus, when the bandage is applied at an angle less than 45° with a direction perpendicular to the length of the limb part 4, the strapping can be applied on two consecutive turns as shown in the figure. ., while being applied mainly to the upper turn of these two turns. In other words, depending on the embodiment of the , the strapping extends mainly on the upper end turn 10 and marginally on the previous turn.

It is understood that the bandage may comprise more than one compression band 1, for example two compression bands. In this case, the strapping is applied to the outer compression band 1, which covers another compression band. The two compression bands are for example applied in opposite winding directions, which reduces the sliding of the outer compression band on the inner compression band, this sliding being further reduced by the presence of the strapping formed by the device. maintenance. Alternatively, the strapping can be applied between the inner compression band and the outer compression band, i.e. the strapping is applied to the inner compression band. In this case, the interior face of the retaining strip(s) 2 forming this strapping comprises a fixing device arranged to cooperate with the exterior face of the interior compression strip and the exterior face of the retaining strip(s) 2 forming the strapping comprises a fixing device arranged to cooperate with the interior face of the exterior compression band.

It can also be envisaged to provide more than one holding device in order to form strappings around several zones of the bandage or one or more holding devices comprising several holding strips 2 around circumferences of limbs greater than the length of the strip , as described previously.

The retaining strip(s) 2 being formed by one or more distinct pieces of the compression band 1, these can be used with different models of compression band. In other words, it is not necessary to produce a support strip 2 specific to a model of compression band 1. In addition, the support strip(s) 2 can easily be removed when the bandage must be redone and then repositioned when the bandage has been redone. If, on this occasion, the compression band needs to be changed, it is not necessary to also change the support band(s) 2.

The compression device has been described for application to a patient's leg. It is understood, however, that the compression device can be applied to another part of the limb, such as a forearm, the lower turn of the bandage being for example wrapped around a hand or a wrist and the upper turn of the bandage being for example rolled up near the elbow.
