Description

CUFF FOR RECEIVING AT LEAST ONE PART OF EXTERNAL EXTREMITY OF A PERSON

The present invention relates to a cuff for receiving at least a portion of an outer extremity of a person. The development of new machine-assisted training and rehabilitation facilities and methods is increasing year by year. Rehabilitation mechanisms as known for example from WO 2017/063639 Al, can advantageously allow a regular cost-efficient mobilization of bedridden patients at the earliest possible date, which can sustainably positively affect the recovery of patients. In addition, a variety of exercise equipment in particular for the implementation of running training, such as that of DE 10 2011 107 382 Al, known, which can increase its physical performance assets through interaction with the runner, the muscle and tendon apparatus but advantageous to spare.

For the interaction between such rehabilitation mechanisms or training devices and humans, recording devices in the form of Harni's, straps and / or cuffs are always necessary. Depending on the specific field of application, these recording devices have very different technical requirements. While in exercise equipment for the running training of healthy runners in addition to a controlled power transmission and - distribution of the device on the people, especially a comfortable feeling in the foreground can stand on Aufhahmevorrichtungen, in the context of the rehabilitation of intensive care patients are used come, in addition partially completely different, often more complex requirements, especially in the field of hygiene and / or ease of use when creating and losing weight by the user or by a third party. Afflicted persons, in particular intensive care patients, are often almost completely limited in their freedom of movement due to their own muscular weakness, possible unconsciousness and / or connected diagnostic apparatus, catheters and the like. If such a patient to be mobilized with machine assistance, must be provided for the connec tion man-machine recording devices, which are easy to put on and take off, gestate an optimal implementation of the desired Be exercise and at the same time leave the often life-sustaining device connections to diagnostic and therapeutic devices unaffected. In addition, there is an increased requirement for cleaning options in the field in order to ensure perfect hygienic conditions for the patient.

From DE 33 35 251 Al a thigh cuffs made of thermoplastic material for orthopedic purposes has become known, which advantageously adapts to the thighs of the user due to their special shape and their special closure mechanism and thereby advantageously avoids blood congestion and the formation of pressure points. A connection to rehabilitation mechanisms and / or training ningsgeräten is not provided here.

The present invention therefore has the object of providing an improved in comparison to the prior art Aufhahmevorrichtung for receiving at least a portion of an outer limb of a person who in a hygienic environment optimized power transmission from a machine, in particular a rehabilitation mechanism or training device, allows a person to be easy and, in particular, by third parties to the person to put on and take off and any further device connections between the person and other diagnostic and therapeutic devices without interference gestatet.

This object is achieved with a cuff for receiving at least part of an outer limb of a person having the features of independent claim 1.

A cufflink according to the invention is based on a cuff comprising: an inner structure intended for engagement with the outer extremity of a person, bounded by two shorter sides opposite each other and two longer sides opposite each other;

and an inner structure supporting the outer structure, which is bounded by two opposite shorter sides and two opposite to each other the longer sides;

wherein on the outer structure at least a first and a second fastening means are arranged for fastening a support means of a relief system,

and wherein the sleeve has at least one, a Weiteverstellung ermög lichenden, closure, comprising a first closure member and a second closure member for reversibly securing the two shorter sides of äuße ren structure or the two shorter sides of the inner structure together,

and wherein the internal structure of the sleeve according to the invention comprises a cavity which is filled with a fluid which distributes within the cavity at least in sections over the sleeve surface spanned by the longer and shorter sides of the internal structure of the sleeve.

A cuff according to the invention advantageously allows the safe, comfortable and injury-free recording of outer extremities, in particular of a thigh of a person. About the filled with a fluid inner structure of the cuff pressure and force effects of the cuff are distributed to the outer extremities, insbesonde on the thigh of the person, advantageously evenly over the entire support surface of the cuff. This increases the wearing comfort and avoids pressure points or punctual (over) burdens and injuries of the extremities. The, a Weitenver position enabling closure, comprising a first closure member and a second closure member for reversible attachment of the two shorter sides of äuße Ren structure or the two shorter sides of the inner structure together, advantageously allows easy on and off of the sleeve by the person himself or by a third party, such as a physiotherapist or the nursing staff.

Further advantageous embodiments and further developments, which are used individually or in com bination with each other, are the subject of the dependent claims. In a preferred embodiment of the invention, the inner structure, in particular its cavity, in at least two interconnected segments be divided up so that the fluid can be distributed between the segments. The segments can be formed, for example, in that the two opposing the sleeve surfaces of the inner structure at selected points ver together, preferably welded and / or glued, and thereby form so-called. Webs. The connection of the segments with each other then advantageously ensures the filling and / or uniform distribution of the entire cavity with the fluid.

In a further embodiment, it has proven particularly useful that the inner structure, in particular its cavity, is divided into a plurality, preferably between 10 and 20, of segments connected with each other in such a way that the fluid can be distributed between the segments, wherein the Segments are aligned with respect to their catches substantially along the longer sides, substantially along the shorter sides or partially substantially along the longer sides and partially substantially along the shorter sides. A segmentation of the cavity advantageously prevents the fluid, especially during a change in the Fagen (during movement) of the cuff, (too) fast on one side of the sleeve (according to gravity) moves. The distribution of force from the cuff to the extremity of the person remains so advantageously constant. In addition, the segmentation prevents the two opposite, spanned by the shorter and longer sides, Manschet tenflächen move against each other and thus ensures improved stability and improved adhesion to the limb. The segmentation may be different. The webs formed by the connections between opposite cuff surfaces of the internal structure may be arranged in the direction of the shorter or longer side or combined. A catching arrangement (ent long the longer side), especially in the edge region, simplifies the creation of the man cuff, since the ends of the cuff at the overlap better together before. When aligning the webs in the other direction, the creation is difficult because there is a slight blocking of the short side by the webs.

In a preferred embodiment, the fluid may be a gel-like substance, in particular a mixture of sodium polyacrylate and water. The normally higher viscous sity of a gel compared to a liquid, such as water, tet also ensured when changing the position of the cuff during a movement of the person a uniform distribution of the fluid over the entire internal structure, in particular its special cavity. In case of damage to the internal structure, a gel also advantageously remains longer inside the cavity and allows re-waterproofing of the internal structure, without contaminating the environment by running out of the fluid too much.

In addition, an embodiment of the invention has been proven in which the outer structure comprises at least one support member which supports the sleeve along the length ren pages and / or the shorter sides flexible. The at least one flexible support zelement supports the sleeve, in particular the sleeve surface, advantageously from a shorter side to the opposite shorter side and / or from a longer side to the opposite longer side, thereby ensuring an improved, in particular special uniform, power transmission to the extremities the flexibility of the sleeve, in particular in the context of bending the two shorter, each other against opposite sides to each other, guaranteed.

It may be preferred if the at least one outer structure comprises at least one outer cover layer and at least one inner cover layer, which encase the support ele- ment to the outside or inside. The outer cover layer protects the proppant and the inner structure advantageous against contamination, whereas the inner cover layer protect the inner structure, in particular against the action of Stützmit means, in this way avoid penetration of the support member into the cavity and prevent leakage of the fluid advantageous ,

In addition, it has proven useful if the support element is formed from a spring steel and / or a glass fiber reinforced plastic. Both classes of materials are good bear beitbar and advantageously serve as a cost-effective and robust Ausgangsmate materials for the preparation of a support element.

In a preferred embodiment of the invention, the support element may extend over at least a portion of the collar surface and / or include cutouts to increase the flexibility of the support member. By at least a part of the Manschetenfläche extending support element in particular the inner structure is supported before geous. Any existing cutouts advantageously increase the flexibility of the support element while maintaining the support effect.

In an alternative embodiment, the outer structure may also comprise a plurality of Stu zelementen in the form of individual Famellen, which are aligned with respect to their catches substantially along the shorter sides of the outer structure. Single nen Famellen offer the advantage that in the case of a complete collapse pens cufflinks breaking or bending the Stützmitel is avoided.

According to the invention, an embodiment in which the at least one outer structure and the at least one inner structure are seamlessly connected to one another is also preferred. A seamless connection of the two structures, preferably via welding seams or by a flush bonding, advantageously prevents contamination in any space between the inner and outer structure and makes the cleaning and / or disinfecting the cufflinks easier and more time efficient.

In a further preferred embodiment, a filling valve for filling the inner structure, in particular its special cavity, may be provided on the outer structure and / or on the inner structure of the cufflinks. A filling valve advantageously offers a filling possibility and / or refilling possibility for the fluid. It is preferably arranged on the externa ßeren structure, as so advantageous direct contact with the person and thereby the risk of injury to the person can be further minimized.

In addition, it is preferred if the cuffs, in particular their inner structure, at least partially made of plastic, wherein the plastic is biocompatible, preferably a thermoplastic polyurethane. Alternatively or cumulatively, the cufflinks, in particular their inner structure, can also be provided with a casing made of a biocompatible plastic. The use of a biocompatible plastic for the production of cuffs or the provision of a shell made of biocompatible synthetic material advantageously allows direct skin contact. This may, especially in Intense patients, who usually wear no pants, but only quickly changing hospital nightgowns, facilitate the recording through the cuffs and still allowed a comfortable for the patient's use. The use of art Fabric also simplifies the cleaning of the cuff and thus advantageously allows a time-efficient disinfection.

In a preferred embodiment according to the invention can also be arranged on the outer structure at least a first and a second fastening means for fixing a Tragmit means of a relief system. With the aid of these fastening means, the sleeve can be advantageously connected to a relief system, in particular a Körperge weight relief system of a rehabilitation mechanism.

It has proven in a preferred embodiment that the fastening means along the longer sides and / or the shorter sides of the outer structure are displaceable bar. If the fastening means are designed to be displaceable, the fastening means can be arranged depending on the diameter of the thigh of the person on the cuff, that on the cuff on the Befestigungsmit tel a uniform tensile force is exerted.

Furthermore, an embodiment of the invention is preferred in which all components permanently connected to the outer structure, in particular the filling valve, the first and second closure part, and the fastening means are connected via seamless connections with the outer structure, in particular with its outer cover layer. A seamless connection of all firmly connected to the outer structure components, preferably via welds or by a flush bond, advantageously allows the construction of a cuff with a smooth surface as possible, which is weitge starting material pockets, overlaps or other bumps, which during would be difficult to access for cleaning and / or disinfecting. By contrast, such a "seamlessly designed" cuff can be cleaned quickly and effectively after each use by simply wiping it with a disinfectant.

A cuff, which is connected to support means of a relief system, preferably characterized by the fact that these for positive and non-positive transmission of longitudinal L and / or shear forces Q on the outer limb of a person, in particular on the thigh of the person is set up. As a result, the most uniform possible pressure and force from the relief system before geous or its Tragmiteln be ensured over the entire contact surface of the cuffs on the outer limb of a person.

The present invention provides a receiving device, improved in comparison to the prior art, in the form of a sleeve for receiving at least a portion of an outer extremity of a person, which allows optimized transmission of force from a machine, in particular a rehabilitation mechanism, to a person. In particular, because of their seamless processing, it is particularly suitable for use in an environment in which high demands are made on cleaning options and hygiene, such as in the rehabilitation of intensive care patients in an intensive care unit. The man invention is simple, especially by third parties to invest in a person or to remove it again and can be advantageous by their closure technique and a possible overlapping of the ends of the mating in the sense of a so-called "one-size-fits-all" solution to adapt to different body sizes. Finally, due to the positioning ability on the outer extremities, in particular on the thigh of a person, advantageously a disturbance of any further device connections between the person and other diagnosis and therapy devices is avoided.

In the following description of preferred embodiments of the present invention, like reference characters designate like or similar components.

Fig. 1 shows an embodiment of a cuff 1 according to the invention with a view to an inner structure 2. The inner, provided for engagement with the outer limb of a person, structure 2 is formed by two opposite shorter sides 201; 202 and two opposite longer sides 203 and 204 limited. A, the inner structure 2 supporting, outer structure 3, which in turn is bounded by two opposite shorter sides 301 and 302 and two opposite longer sides 303 and 304, is ver in Fig. 1 by the inner structure 2 covers (see. Fig. 3 and 4). The longer sides 203 and 204 or 303 and 304 may be the same length or, as shown here, unequal length, in which case the shorter sides 204 and 304 during use by a person preferably to "lower sides" and the longer sides 203 and 303, respectively, then preferably become "upper sides" with respect to the picked extremity. The embodiment shown here with unequal length In the condition of use, sides 203 and 204 or 303 and 304 can advantageously lead to a conical shape (see Fig. 7) which tapers on one side in accordance with the shape of the extremity taken up with respect to the diameter of the collar attached to the extremity.

Are the longer sides 203 and 204 or 303 and 304 of equal length configured (not shown here), a corresponding adaptation to the shape of the limb preference, be achieved that the inner structure 2 in the region of the longer, "unte ren" Page 204 has a larger volume than in the region of the longer "upper" side 203. In this way, if conically long sides 203 and 204 or 303 and 304 just if a conical, adapted to the shape of the limb of the person shape of the particular Construction 2 are generated.

According to the invention, the internal structure 2 comprises a cavity 24 which is filled with a fluid 22 which, at least in sections, spans inside the cavity 24 via the longer, 203 and 204 and shorter sides 201 and 202 of the inner structure 2 of the sleeve 1 , Cuff area 15 distributed. Fig. 6 shows a vertical section along the longer sides 203 and 204 through the inner structure 2, in which the cavity 22 filled with fluid cavity 24 can be seen.

The inner structure 2, in particular its cavity 24, may preferably be divided into at least two segments 23 connected to one another in such a way that the fluid 22 can be distributed between these segments 23. Particularly preferred is an embodiment of the invention in which the inner structure 2, in particular its cavity 24, as shown here, is divided into a plurality, preferably 10 to 20, of interconnected segments 23 such that the fluid 22 between the Can distribute segments 23. The segments 23 may be aligned with respect to their length substantially along the longer sides 203 and 204, substantially along the shorter sides 201 and 202, or partially substantially along the longer sides 203 and 204 and partially substantially along the shorter sides 201 and 202 be, as can be seen in FIGS. 1 and 2 in the context of an exemplary arrangement. The size of the individual segments 23 may be the same or different, and it may be advantageous to reduce the size of the segments 23 to the shorter sides 201 and 202 than in the middle region of the mating surface 15 in order to allow a better overlap of the cuffs 1 in the area of the shorter sides 201 and 202.

FIG. 2 shows an illustration of the layered construction of the cuffs 1 from the perspective of FIG. 1. Below the inner structure 2 here is a Ausgestal direction of, the inner structure 2 supporting outer structure 3 in a kind of exploded drawing to see.

The cuffs 1 can advantageously at least one, a Weitenverstellung ermög lichenden closure, comprising a first closure member 31 and a second closure member 32 and Ver shown here two first closure members 31 and two second closure member 32, for the reversible attachment of the two shorter sides 301 and 302 of the outer structure 3 or the two shorter sides 201 and 202 of the inner structure 2 to each other. By overlapping the first, shorter 201 or 301 with the second, shorter 202 or 302 shorter sides, the cuffs 1 can advantageously be adapted to the circumference of the limb, in particular to the thigh 91 of the person who the. The cuffs 1 according to the invention can thus advantageously provide a so-called "one-size-fits-all" solution.

The closure can also be ausgestal tet in particular as a so-called. Fidlock closure, ie as a magnetic, self-centering quick release with acoustic feedback, which can advantageously increase the ease of use of cufflinks 1. The second closure part 32 can also be advantageously formed as a plastic band, in particular made of a thermoplastic material. In this case, it has proven to be particularly advantageous if the second closure part or parts 32 have corrugations, in particular a corrugated surface, since in this way the interaction with the first closure part or parts 31 can be intensified by increasing the friction (cf. Fig. 7).

As can be seen in Fig. 4, the outer structure 3 advantageously comprise at least one Stützele element 36, which the cuffs 1 along the longer sides 303 and 304 and / or the shorter sides 301 and 302 flexibly. The at least one outer structure 3 may also advantageously be constructed in a layered manner and comprise at least one outer cover layer 37 and at least one inner cover layer 38, which envelop the support element 36 to the outside or inside.

Alternatively or cumulatively, the inner structure 2, a filling valve 14 for Befül development of the inner structure 2, in particular its cavity 24 include. In Fig. 4 is also shown that on the outer structure 3 advantageously at least a first 34 and a second fastening means 35 for attachment of a support means 41 of a relief system 4 can be arranged. These fastening means 34 and 35 may be firmly fixed to the outer structure 3, in particular to its outer cover layer 37, and / or be slidably formed along the longer sides 303 and 304 and / or the shorter sides 301 and 302 of the outer structure 3 (not shown) ).

In FIGS. 5a, 5b and 5c, three embodiments of the support element 36 of the outer structure 3 of the sleeve 1 are shown by way of example. The support member 36 may be preferential example of a spring steel and / or formed from a glass fiber reinforced plastic. As shown in FIGS. 5a and 5b, the support member 36 may extend over at least a portion of the collar surface 15 and / or may include cutouts 361 to increase the flexibility of the support member 36. Alternatively or cumulatively, the outer structure 3 may also have a multiplicity of support elements 36 in the form of individual lamellae 362 which, with respect to their length, may be aligned substantially along the shorter sides 301 and 302 of the outer structure 3 (see FIG. 5c).

It can be seen that the inner structure 2 according to the invention comprises a cavity 24 which be with a fluid 22 be It is possible to disperse within the cavity 24 at least in sections over the collar surface 15, spanned by the longer 203 and 204 and shorter sides 201 and 202 of the inner structure 2 of the sleeve 1. The possibility of distribution of the fluid 22 within the cavity 24 is indicated in FIG. 6 by way of example by crossed arrows which correspond to possible flow directions F. In the illustrated For example, the cavity 24 is divided into at least four segments 23 extending along the shorter sides 201 and 202. The segments 23 may be formed by who the, that two opposing sleeve surfaces 15 are welded together wenigs least sections and / or glued, whereby webs 361 may be formed, the individual areas of the cavity 24 at least partially separate from each other. In FIG. 6, it can further be seen that these segments 23 are preferably connected to one another, so that the fluid 22 extends at least in sections beyond the, through the longer 203 and 204 and shorter sides 201 and 202 of the inner structure 2 of the sleeve 1, Cuff area 15 can distribute. Here, for example, the webs 361 do not extend over the entire width of the collar surface 15 and thus permit a connection of the individual segments 23 in the regions near the longer sides 203 and 204. The fluid 22 may preferably be a gel-like substance, in particular a mixture of sodium polyacrylate and water.

Fig. 7 shows an embodiment of a cuff 1 when used by a person with fasteners 34 and 35 for attachment of a support means 41 ei Nes relief system (not shown here). It can be seen how a thigh 91 of a person is taken up by a cuff 1.
