Technical Field

The present invention relates to a compression garment, in particular stockings or a bandage, for applying compression to a body part.

Background Art

Compression garments are used to provide a pressure or a compressive force, respectively, to a human body part, especially to a limb such as an arm or a leg for e.g. the treatment of venous diseases and lymphatic disorders. Medical compression garments are elastic or inelastic garments and can, for example, be used to compress a lower leg, an entire leg, an arm, a hand and so on. They are known to be designed as stockings, socks, panties, arm sleeves, gloves etc.

Many patients do not wear their compression garments due to difficulties in donning the garment and in dosing the compression force. Donning a compression garment over the lower leg is especially laborious. The torso has to be bent strongly forward if both hands are used at the same time for donning the compression garment . Disclosure of the Invention

The object of the present invention is to provide a compression garment which is easy to don.

In order to meet this object, a first aspect of the invention introduces a compression garment according to claim 1.

The compression garment comprises an elongated stretchable sleeve, a compression part and a closing part .

The elongated stretchable sleeve might be stretchable in both circumferential and longitudinal directions. The elongated stretchable sleeve has an inner surface and an outer surface and the sleeve is adapted to be worn over the body part to be compressed. The compres- sion part is connected to the elongated stretchable sleeve and the at least one closing part is provided for fixing the compression part in a wrapped around state in which the body part is compressed by said compressing part .

The compression part is shaped and sized to be wrapped around at least a portion of the circumference of the elongated stretchable sleeve and the compression part is adapted for positioning proximate to the outer surface of the elongated stretchable sleeve. The compression part provides a compression force to the body part and is fixable by the closing parts in the wrapped around state to maintain the compression force.

This design allows an easy donning of the compression garment. While the compression part has the main function to generate the compression force, the elongated stretchable sleeve is primarily acting as a donning aid.

In a first step, the elongated stretchable sleeve can easily be pulled over the leg to bring the compression garment into position at the body part to be compressed. In a second step, the compression part, which is connected to the elongated stretchable sleeve, can be wrapped around the stretchable sleeve and thus around the body part by pulling on the compression part or pulling on the closing part connected to the compression part with one hand only. Then the compression part can be fixed by the closing part in the wrapped around state to secure the compression part in its wrapped around state providing the compression force to the body part.

The main advantage of the disclosed compression garment is that it can easily be donned only by one hand. The elongated stretchable sleeve stays steady in its position relative to the body part and does not rotate during wrapping around of the compression part even if considerable pulling force is exerted, since the compression part, when wrapped around the elongated stretch- able sleeve, presses the elongated stretchable sleeve onto the body part and a rotating movement of the elongated stretchable sleeve is thus avoided due to friction. Therefore, while donning the compression garment, the compression part is held by the elongated stretchable sleeve on one side and is pulled by hand on the other side, either by pulling on the compression part or on the closing part. Thus it is not necessary that one part of the compression garment has to be held by one hand while the compression part is wrapped around and fixed by the other hand as in conventional devices.

In an advantageous embodiment, the compression part extends as a continuous part over the full length of the stretchable sleeve. In other words, the compression part is not designed as a plurality of tensile stripes, which generate local compression, but a continuous compression part is provided, which extends over the full length of the sleeve. A continuous compression part generates its compression force over the full body part to be compressed. In another advantageous embodiment, the compression part extends on one side even further than the length of the stretchable sleeve or the compression part extends on both sides further than the stretchable sleeve.

In an advantageous embodiment, the compression part extends over the full length of the body part to be compressed.

The extension over the full length of the body part allows an even pressure distribution over the full body part to be compressed.

In another advantageous embodiment, the compression part comprises a first end and the compression part is connected to the elongated stretchable sleeve by said first end only. A second end of the compression part is located opposite to the first end and the at least one closing part and preferably a plurality of closing parts are arranged adjacent to the second end. In another embodiment the edge of the elongated stretchable sleeve is sewn in with an offset from the edge of the compression part .

The first end and the second end have a functional meaning. If the compression part is wrapped around the stretchable sleeve, the force between the elongated stretchable sleeve and the compression part is transmitted over the first end of the compression part and the force between the compression part and the closing parts is transmitted over the second end of the compression part .

It is further preferred that the elongated stretchable sleeve is shaped and sized such that elongated stretchable sleeve alone applies an averaged pressure of less than approx. 15 mmHg (approx. 2000 Pa) , in particular less than 10 mmHg (1333 Pa), in particular less than 5 mmHg (667 Pa), in particular less than 3 mmHg (400 Pa), to the body part.

The low pressure generated by the elongated stretchable sleeve allows an easy donning of the compression garment since the elongated stretchable sleeve can easily be pulled over the body part. Furthermore, a too high minimum pressure, which would act permanently on the body part by the elongated stretchable sleeve is avoided, but the pressure can individually be set to the preferred intensity by applying compression force by the compression part as much as wanted.

In another preferred embodiment, the elongated stretchable sleeve has a tubular form and/or is adapted to receive a leg or an arm.

In particular if the compression garment is designed to compress a leg, it can be donned more easily compared to conventional compression garments because only one hand is needed for donning it such that the torso does not have to be bent forward so much as with conventional garments. Donning is easier because the elongated stretchable sleeve goes easier over the heel as a medical compression stocking. The medial or lateral closure is easy to reach compared to garments with a closure over the shinbone area.

Advantageously, the elongated stretchable sleeve is integrally made of a material different than the material of the compression part or in the alternative the elongated stretchable sleeve is made in part of the material of the compression part and in part from a material different than the material of the compression part .

Preferably, the elongated stretchable sleeve shall not be thicker than 1 mm and have a stretchability of at least 100% in the preferred circumferential direction .

Furthermore, the compression part is preferably made of a spacer fabric.

In another advantageous embodiment, the com- pression part has an inner surface and an outer surface. Preferably, the at least one closing part and the outer surface of the compression part and of the elongated stretchable sleeve are adapted such that the at least one closing part can be attached to the outer surface of the compression part.

According to another aspect of the invention, a compression garment comprises a compression part, at least one closing part and at least one mark or gauge, respectively, applied to the at least one closing part for indicating when a proper amount of stretch has been reached by the closing part. The stretch of the closing part is an indication for the compression force applied by the compression part. The compression garment comprises at least one cover which at least partly covers the at least one closing part. The closing part is covered by the cover such that the at least one gauge is covered by the cover as long as a sufficient amount of stretch has not been reached and the at least one gauge is uncovered after a sufficient amount of stretch has been reached.

Alternatively the cover comprises a window such that the at least one gauge is covered by the cover if sufficient stretch has not been reached and is visible in the window if sufficient stretch has been reached, or is visible in the window if sufficient stretch has not been reached and is covered if sufficient stretch has been reached. A window can be an opening or a transparent cover, for example.

This embodiment has the advantage that the user realizes in a clear way when enough stretch has been reached within the closing part and thus indicating enough compression by the compression part while donning the compression garment. Enough stretch has been reached as soon as the gauge appears because it is not covered anymore or it disappears because it is covered after hav- ing been uncovered, depending on the design of the cover and the gauge.

The gauge can be designed as a simple line, or as any kind of figure.

More than one gauge can be applied to one closing part such that different levels of stretch can be indicated .

Furthermore, the at least one cover is preferably shaped as a bag. The at least one closing part is partly arranged inside the at least one bag such that the at least one closing part with the gauge can be pulled out of the bag.

Preferably, the garment of this second aspect of the invention is a garment according to the first aspect of the invention.

Another object of the invention is to provide a method for donning a compression garment.

This object is met by a method with the features of claim 13.

Other advantageous embodiments are listed in the dependent claims as well as in the description below.

Modes for Carrying Out the Invention

Advantageous embodiments of the invention are shown in Figs. 1 to 7. Fig. 1 illustrates a compression garment which is adapted to be wrapped around a leg. The garment comprises an elongated stretchable sleeve 1 which is connected to a compression part 2. Furthermore, the compression garment comprises closing parts 3 connected to the compression part 2, in this example six closing parts 3, wherein each closing part 3 comprises at least one hook, in this example two hooks 4. The connection of the elongated stretchable sleeve 1 and the compression part 2 can be made of a stitched seam if both parts 1 and 2 are made of a fabric.

The compression part 2 has a first end 21 and a second end 22 wherein the second end 22 is located opposite to the first end 21. The first end 21 is located where the compression part 2 is connected to the elon- gated stretchable sleeve 1 and the second end 22 is located where the closing parts 3 are connected to the compression part 2. The closing parts 3 are made of a more stretchable material than the compression part 2 so that by stretching the closing parts and securing them to the compression part 2, preferably by hooks 4 or by other means, the compression part is held in its wrapped around state .

The compression part 2 extends over the full length 11 of the elongated stretchable sleeve 1 as shown in Fig. 1. In another embodiment, the compression part 2 may extend even further than the full length of the elongated stretchable sleeve at one of the opening sides of the stretchable sleeve 1 or the compression part 2 may extend further than the full length of the stretchable sleeve on both opening sides. This is indicated in Fig. 1 by a line 1' and a line l' ¹ which shall indicate that the stretchable sleeve may end there, so that in this case its full length would be shorter than shown with arrow 11. A shorter stretchable sleeve will be easier to slip- through with the foot (see Fig. 4a) and as well be easier to place it on the lower leg (see Fig. 4b) .

Fig. 1 shows a view directed to the spread out garment and to the outer surface 16 of the elongated stretchable sleeve and to the inner surface 25 of the compression part 2. If donned, the inner surface 25 of the compression part is in contact with the outer surface 16 of the elongated stretchable sleeve 1. Fig. 2 illustrates a compression garment with a view from above to the slip-in side of the elongated stretchable sleeve 1. The elongated stretchable sleeve 1 has a tubular form with a diameter 12 and a circumference 13 when being in an unfolded state as shown. If the compression garment is not donned, the circumference 13 of the elongated stretchable sleeve should optimally be somewhat smaller than the circumference of a body part, e.g. a leg, onto which the elongated stretchable sleeve 1 is pulled over.

The elongated stretchable sleeve 1 is made of a material which can be stretched with little effort so that only little strength is needed when donning it.

The compression part 2 is connected to the elongated stretchable sleeve 1 at its first end 21. At the second end 22 of the compression part, the closing parts 3 with hooks 4 are arranged. The compression part 2 is illustrated in Fig. 2 by a bold line.

The elongated stretchable sleeve 1 has an in- ner surface 15. When the garment is donned, the inner surface 15 of the elongated stretchable sleeve faces the skin of the body part, the outer surface 16 of the elongated stretchable sleeve 1 is in contact with the inner surface 25 of the compression part 2 and the outer sur- face 26 of the compression part 2 is the outermost surface of the compression garment.

The closing parts 3 with the hooks 4 are provided to be hooked into the outer surface 26 of the compression part 2.

The compression part 2 may extend with its end opposite the closing parts even a bit further than shown by the preferred embodiment of Figs. 1 and 2. This is indicated in Fig. 2 by the dotted line showing a short section of the compression part extending over the con- nection line with the stretchable sleeve 1 and defining a free end 21'. In this case the reference 21 would only denote the connection line and not the end of the compression part which is denoted in this embodiment by 21'.

Fig. 3 illustrates an alternative design of a compression garment. In this embodiment, the elongated stretchable sleeve 1 is made of a textile part 14 which is attached on its one side to the first end 21 of the compression part 2, i.e. it is attached to the inner surface 25 of the compression part 2. On the other side it is attached to an extension of the compression part 2, which is therefore a part of the elongated stretchable sleeve 1.

This example shows that such terms as "elongated stretchable sleeve", "first end", "compression part" etc. have to be understood in a functional way.

In other words it can be said that the stretchable sleeve may be attached at different locations on the inner surface 25.

Fig. 4a to 4d illustrate a donning process, wherein the compression garment is donned over a lower leg.

In a first step (Fig. 4a), the elongated stretchable sleeve 1 is pulled over the lower leg by slipping-in foot first from one side into the tunnel- shaped elongated stretchable sleeve 1 and then pulling this sleeve over the lower leg. This step can be performed by only one hand. The elongated stretchable sleeve 1 is just brought into position on the lower leg in order to wrap the compression part 2 around the lower leg in further steps. By pulling the elongated stretchable sleeve 1 over the lower leg, the elongated stretchable sleeve 1 has to be stretched only with little effort.

As soon as the elongated stretchable sleeve 1 has been brought into position, it doesn't slide down since enough friction is provided between the elongated stretchable sleeve 1 and the lower leg because the elongated stretchable sleeve 1 is stretched by the lower leg. In a second step (Fig. 4b and Fig. 4c), the compression part 2 and the closing parts 3 are wrapped around the lower leg. This step can be performed by only one hand since the compression part 2 is pulled from one side by the hand (from end 22) and the compression part 2 is held by the elongated stretchable sleeve 1 from the other side.

The more the compression part 2 is wrapped around the leg, the larger is the area 5 where the inner surface 25 of the compression part 2 touches the outer surface 16 of the elongated stretchable sleeve 1 and presses it to the lower leg. Hence, the compression garment is held even more stable in position and the compression part 2 can be pulled very strongly by one hand and the elongated stretchable sleeve 1 doesn't slip around the lower leg.

In a last step (Fig. 4d) , the compression part 2 is attached in a stretched state by fixing the closing parts 3 to the compression part 2. Therefore, all steps for donning the compression garment can be performed by one hand which facilitates the donning process remarkably. Fig. 4d shows the closing on the medial side of the leg but of course the garment can be provided such that the wrapping around is done to the other side so that the closing parts of the garment are on the lateral side of the leg when the compression part has been wrapped around or any other position such as anterior or posterior aspects of the leg.

It is preferred that the elongated stretcha- ble sleeve is shaped and sized such that the elongated stretchable sleeve alone applies an averaged pressure of less than approx. 15 mmHg (approx. 2000 Pa) , in particular less than 10 mmHg (1333 Pa), in particular less than 5 mmHg (667 Pa), to the body part.

Fig. 5 illustrates an example embodiment for explaining the second aspect of the invention, this garment comprising a compression part 2, six closing parts 3 and six covers 6, such that every cover 6 partly covers one closing part 3. Preferably, this embodiment comprises as well an elongated stretchable sleeve 1. Otherwise only the compression part 2 would be present to be wrapped around the leg in a conventional manner. If there is an stretchable sleeve 1 all the features of the garment explained so far for the first aspect of the invention can be present.

The interaction of a closing part 3 and of a cover 6 is illustrated in detail by the figures 6a to 6d and by the figures 7a and 7b.

Fig. 6a shows a closing part 3 in an un- stretched state with two hooks 4. No mark or gauge 71, 72, respectively, is visible because it is covered by the cover 6. The cover 6 is designed as a bag and the closing part 3 is secured within the bag in the region of the closed end of the bag and is in particular fixed inside the bag at that side 61 which is located opposite to the opening 62. The closing part 3 passes through the opening 62 such that one part of the closing part is covered by the cover 6 and the other part is not covered by the cover 6, i.e. one part is arranged inside and one part is arranged outside the bag.

As soon as the user pulls the closing part 3 in order to stretch the compression part 2, which is connected with the closing part 3, a bigger part of the closing part 3 gets visible because the surface of the closing part 3 increases since the closing part 3 is stretched in the direction indicated by the arrow in Fig. 6b.

If the closing part 3 and the compression part 2 are pulled further, a first mark or gauge 71, respectively, which is in this example designed as a simple line, appears, i.e. it moves out of the bag, and indi- cates that a proper amount of stretch in the compression part and/or in the closing part has been reached, as illustrated by Fig. 6c. In this moment, the user can fix the compression garment in a stretched state by attaching the closing part 3 to the elongated stretchable sleeve 1 or to the compression part 2.

It is also possible that a second mark or more marks or gauges 72, respectively, are applied to the closing part 3 such that different compression levels can be indicated by the first gauge 71 and the second gauge 72, as illustrated by Fig. 6d.

Fig. 7a and 7b illustrate an alternative embodiment of the closing part 3 in an unstretched state (Fig. 7a) and in a stretched state (Fig. 7b). The cover 6 has a window 73 such that the at least one gauge 71, 72 is visible in the window 73 if not enough stretch has been reached and is covered by the cover 6 if enough stretch has been reached or is covered by the cover 6 if sufficient stretch has not been reached and is visible in the window 73 if sufficient stretch has been reached.

The present invention has so far been described for some specific embodiments shown in the figures. It must be noted that it also can be practiced differently.
