Description

TECHNICAL AREA

[0001] The present invention relates to a modular back orthosis system with a back orthosis device comprising a back brace, at least one shoulder strap, and at least one traction element section extending over it, which is advantageously connectable to the back brace and operable for adjusting the force exerted by the shoulder strap and back brace, particularly on the back, and is guided via an adapter advantageously attached / attachable to the back brace. Such a back orthosis device can be retrofitted modularly according to the present invention, in particular by the load-bearing module described herein. The present invention also relates to a corresponding load-bearing module. The present invention also relates to a unit, in particular an (X-ray) apron, to be worn as personal protective equipment and equipped accordingly for coupling with the back brace.Furthermore, the present invention relates to a correspondingly usable load-bearing module which can be modularly connected to such a back orthosis device. Finally, the present invention also relates to device designs for the optimized non-therapeutic use of such a back orthosis device with a load-bearing module, specifically for supporting loads exerted on a surgeon by personal protective equipment, in particular by an X-ray apron, via the orthosis and the lower back region, and optionally also the hip. In particular, the invention relates to devices according to the preamble of the independent claim. BACKGROUND OF THE INVENTION

[0002] Back braces are used, for example, for upper body extension and typically feature two shoulder straps connected to a back brace. Putting on a back brace is similar to putting on a backpack. The correct, individualized function of the shoulder straps and the forces transmitted through them are of paramount importance, particularly with regard to extension. Depending on the application, individual adjustment of the back brace, and thus of the force exerted on the person and the resulting degree of postural change, is desirable or even necessary from a medical, especially orthopedic, perspective.The putting on or taking off of the back brace and / or the adjustment of the back brace should each be possible in the simplest and most ergonomically advantageous way possible, if necessary even without the assistance of specialists, and preferably even by the wearer alone.

[0003] An example is the publication WO 2023 / 098 936 A1, which describes an ergonomically optimized back orthosis with advantageous adjustment options for shoulder and pelvic straps.

[0004] Publication US 2021 / 0393466A1 describes an exoskeleton with at least an approximately vertical column arrangement and an associated frame that conforms to the shape of the back, whereby the exoskeleton can also transmit loads exerted by a unit worn in front of the body.

[0005] Based on the current state of the art, there is a need for further applications and even greater functional integration of such back braces, particularly with regard to effectively reducing the strain on the back during specific uses. Furthermore, especially given the high costs, particularly in the areas of medical and hospital equipment, there is interest in synergistic effects, especially based on the most sustainable and cross-sectoral use of back braces possible. SUMMARY OF THE INVENTION

[0006] The objective is to provide a back orthosis device that not only fulfills its primary medical / medical-technical function (especially extension), but also at least one additional function, particularly regarding the even better / more effective reduction of loads acting on the wearer, especially for the purpose of further improving usability, synergistic effects, and good product sustainability. It is also the objective to design a back orthosis device in such a way that a comparatively high load-bearing capacity and transmission can be achieved with minimal strain on the wearer. Finally, it is the objective to design such a back orthosis device in such a way that this type of back orthosis device can be used synergistically for different applications with minimal adjustment effort.

[0007] This problem is solved by a modular back orthosis system comprising a back orthosis device according to claim 1 in combination with a suitably configured load-bearing module. Advantageous embodiments of the invention are explained in the dependent claims. The features of the exemplary embodiments described below can be combined with one another unless explicitly stated otherwise.

[0008] A modular back orthosis system with a back orthosis device for shoulder / back relief of a unit to be worn is provided, comprising a back splint that rests against the spine and is flexible in the sagittal plane, comparatively rigid in a frontal plane, and also rigid in cranio-caudal extension, and at least one shoulder strap and at least one traction element section guided in the area of ​​or in extension of the shoulder strap, which is coupled / connectable to the back splint and is operable for adjusting the force exerted by the shoulder strap and back splint, particularly on the back, and is guided via an adapter attached / attachable to the back splint, wherein the back orthosis system has a hip belt that can be connected / connected to the back splint; according to the invention, it is proposed thatThe back brace device has a load-bearing module that can be connected to / is connected to the back brace for shoulder / back relief and is designed to transfer (gravitational) loads caused by a unit worn over the shoulder and / or neck (especially personal protective equipment) into the back brace, particularly into a section of the back brace that is as low as possible, namely when the unit is suspended above the shoulders. This significantly expands the range of applications for this type of back brace device. In other words, the respective back brace device is not necessarily only provided for patients, but can also be used, for example, by doctors or clinical staff.Especially preventively and / or as a substitute for a significantly more complex system, e.g., to relieve surgeons of the burden of wearing personal protective equipment such as a (frontal) X-ray apron for a comparatively long period, particularly repeatedly, e.g., several hours per workday. This allows for the generation of synergistic effects, e.g., in everyday clinical practice, in addition to effective preventive protection.

[0009] The back orthosis device has a fastening unit attached / attachable to the back rail, via which the unit to be worn can be supported on the back rail.

[0010] The modular back orthosis system also features a frame / side panels and a corset structure, with the load-bearing module designed to completely bridge the thoracic spine area without any support. The modular back orthosis system is also designed for height adjustment via the back splint.

[0011] It is understood that the back orthosis device described here is primarily intended for use as a medical device. However, this use can be qualified within the scope of the present invention insofar as the back orthosis device can also be used by individuals who do not (yet) require therapy, but merely desire / demand relief or a reduction in upper body strain, for example, in the daily routine of operating rooms in hospitals. In this respect, the back orthosis device described here offers, compared to other types of back support units or back / hip support units, the advantage of excellent ergonomics and adjustability, as well as the advantages described here based on the modular coupling concept. Advantageously, the support function for, for example, an X-ray apron can also be retrofitted optionally thanks to the modular coupling concept.The respective back orthosis device can be individually equipped for its specific purpose. This allows for further synergy effects regarding the procurement and use of the back orthosis device described here.

[0012] Particularly in light of previous concepts for relieving back strain (e.g., sensor-controlled X-ray apron lifts, ceiling mounts, pelvic belts), the present invention offers an elegant, ergonomic, and medically valuable method of support, with advantageously ergonomic handling. Previous concepts, whether aimed at passive or active weight reduction, suffer from the disadvantage that the actual forces acting upon them can hardly be reduced, or that the effort and complexity of handling become disproportionately high, especially with ceiling suspension. Further disadvantages include excessive wear and tear on the aprons and the limited improvement achieved in reducing the progression of thoracic kyphosis. The present invention overcomes these disadvantages.

[0013] The stabilizing orthosis type of back orthosis is advantageous for vertebral fractures or other diseases of the spine, especially with pelvic / lumbar imaging.

[0014] According to the present disclosure, "force" refers in particular to the force exerted by the back orthosis device on the individual wearing the back orthosis device in a medical / medical-technical sense, especially a force applied for reclination, and in particular a force adjustable by means of the shoulder straps or traction elements acting on them. The shoulder straps, for example, attach to an upper end of the back brace and are guided back to the back brace under the respective arm crease.

[0015] According to the present disclosure, the term "load" refers in particular to the weight force and any other stress conditions associated with carrying the load caused by an additional object carried by the individual over the shoulder and / or neck (here also referred to as an application-specific additional unit), for example caused by personal protective equipment such as an X-ray apron.

[0016] According to the present disclosure, the term "unit" (standalone term) refers in particular to an item used as personal protective equipment, such as an apron worn in front of the upper body. This item is fundamentally independent of the back orthosis device. However, according to the invention, this item can optionally also be advantageously provided and handled in combination with components of the load-bearing module (in particular, the support unit and one of the coupling parts, advantageously in a one-piece or at least already permanently connected configuration).

[0017] A back brace is understood to be, in particular, a component of the back orthosis device that extends primarily cranially and caudally, resting against the spine and designed to absorb and transmit forces and loads. Advantageously, the back brace is relatively flexible in the sagittal plane, but relatively rigid in the frontal plane, and also rigid in its cranial-caudal (vertical) extension.

[0018] It should be understood that the exemplary reference provided here to loads or stresses caused by X-ray aprons is purely illustrative and does not limit the possible applications of the back orthosis device described here. Rather, the present invention is also based on the concept of providing the back orthosis device in such a modular and retrofittable manner that the load-bearing module can also be used in conjunction with other objects / units (in particular, different types of personal protective equipment, such as different aprons from other industries / sectors, e.g., the steel industry, or particularly heavy coats or jackets, e.g., from the field of disaster relief), for example, by specifically adapting the freestanding, shoulder-spanning support unit of the load-bearing module to the respective object (load, unit), e.g.,by adjusting the length and / or the elasticity and / or the area moment of inertia. The person skilled in the art can implement these application-specific features based on the present disclosure, e.g., by adjusting the cross-sectional geometry and / or the absolute size ratios, in particular of the support unit.

[0019] It is understood that the modular approach according to the invention, at least with regard to the load-bearing module of the back orthosis device, allows the back orthosis device to be provided either independently or decoupled from the load-bearing module, or at least decoupled from some components of the load-bearing module. Alternatively, it can also be provided with a pre-assembled load-bearing module or at least with pre-assembled components of the load-bearing module, in particular components of the back splint up to one of two coupling parts. Whether it is expedient to provide components of the load-bearing module, e.g., at least one support bracket or one / the entire support unit, particularly in combination with a coupling part, already in conjunction with the unit to be supported (e.g., apron), will depend on the specific application.Based on the present disclosure and the respective value chain, the person skilled in the art can identify which components of the load-bearing module are advantageously already provided in device-related connection with the back orthosis device.

[0020] Personalized terms, unless explicitly formulated in the neuter form, may refer to all genders within the context of this disclosure (e.g., "the person skilled in the art"). Any foreign language expressions or abbreviations used here are standard industry terms and are familiar to those skilled in the art.

[0021] According to one embodiment, the back orthosis device, in conjunction with the load-bearing module, is designed to provide free-standing support for an apron, particularly an X-ray apron, especially one weighing at least 8 kg, preferably at least 10 kg. This facilitates prolonged use of such personal protective equipment, especially in everyday clinical practice, without placing significant strain on the wearer's back. Advantageously, the support can be provided by a support unit of the load-bearing module using elastic brackets spanning the shoulders, positioned at a height just above the shoulders. The load-bearing module is designed such that the entire thoracic spine is bridged without any support.

[0022] It is understood that, according to the present disclosure, while the support unit is described as having (material-)elastic properties, it is desirable that the stirrups, in particular, exhibit largely rigid behavior. In other words, the stirrups are designed to be material-elastic to enable the functionality described here, but at the same time, they are sufficiently (structurally) stiff and inflexible to position and permanently hold the unit to be supported in a clearly defined, predefined position above the shoulders. Therefore, even an elastic preload on the stirrups caused by the supports of the unit to be supported does not necessarily lead to any significant deformation of the stirrups; rather, they preferably retain at least approximately their shape and orientation even under the intended load.

[0023] According to one embodiment, the load-bearing module has a coupling device (or coupling module) designed for the positive-locking coupling and support of one coupling part onto another coupling part of the coupling device, in particular by means of at least one male and at least one female coupling section. This also facilitates a practical attachment and removal process for the unit (or skirt) to be carried, especially without additional assistance from another person. Optionally, guide elements or sections can be provided to facilitate the coupling process, such as magnetic guides or holding devices.

[0024] According to one embodiment, the coupling device has a pin- or rod-like pluggable coupling part, in particular a coupling part supported on the mounting unit of the load-bearing module, comprising at least one male coupling section projecting upwards. This also facilitates blind coupling (at the back) by the person carrying the load. Optionally, the orientation of the male and female coupling sections can also be inverted.

[0025] According to one embodiment, the coupling device has holding means for holding coupled coupling parts of the coupling device, for example, magnetic holding means. This can, on the one hand, secure the coupled arrangement, and on the other hand, facilitate the coupling process by magnetically guiding the coupling partners relative to each other.

[0026] According to one embodiment, the fastening unit ensures at least an approximately rigid vertical bridge between an attachment point on the back brace and a relatively more elastic section of the load-bearing module, in particular a vertical bridge that slopes slightly backwards dorsally. This also facilitates an advantageous method of connecting the load-bearing module to the back brace.

[0027] According to one embodiment, the fastening unit has a ventrally oriented underside, which is geometrically corresponding to a dorsally oriented outer surface of the adapter and / or the back rail, in particular each comprising at least one positive-locking contour. This enables optimization of the connection of the load-bearing module and the force transmission into the back rail, each in an advantageous relative position on the back rail. The height range of the force transmission is advantageously located low down.

[0028] According to one embodiment, the fastening unit has a V-shaped form and / or is attached indirectly to the back rail via at least one plate or rail and / or directly to at least three, preferably at least five, V-shaped fastening points arranged relative to each other, in particular directly above or directly below the adapter (advantageously adjacent to the adapter) or on the adapter. This also allows for advantageous docking to the back rail. The V-shape also provides an advantageous force flow path or a load distribution that is as evenly distributed as possible. The fastening unit can optionally comprise a one-piece base (e.g., an injection-molded part), or optionally several tabs or similar parts attached to each other, which form a kind of base via which the fastening unit can be attached to the back rail and the load can be transferred.

[0029] It is understood that the area where the load-bearing module is supported is advantageously located above, below, or on top of the adapter, allowing the modular concept described here to be implemented particularly effectively from a structural point of view and with regard to efficient force transmission. The (weight) force exerted by the unit being supported can thus be advantageously absorbed below the thoracic kyphosis, resulting in a very good load-relieving effect. Particularly with regard to minimizing the number of components, it is advantageous if the load-bearing module is coupled to the back rail via the adapter, for example, using the same screws / fasteners.

[0030] According to one embodiment, the fastening unit comprises a rod-like, height-adjustable connection, preferably having two rods. This facilitates a relatively simple height adjustment of the arrangement of the shoulder-spanning sections of the load-bearing module, e.g., with regard to torsos of different sizes and / or with regard to different loads (e.g., with regard to elastic displacement of the spanning sections or brackets towards the shoulders). In this respect, height variation can also be designed into the fastening unit and / or individually adjustable, in particular such that a support unit of the load-bearing module is positioned freely above the shoulders at an optimal height distance, extending forward over the shoulders, optionally incorporating elastic deformation under load, e.g., from a relatively heavy X-ray apron.

[0031] It is understood that height adjustment can be achieved via the backrest rail, particularly when the mounting unit is supported on the backrest rail by the adapter. Moving / repositioning it a few centimeters up or down is easily accomplished. The mounting, or the designated attachment points on the backrest rail and mounting unit, and optionally also on the adapter, can be designed in such a way that the desired height adjustment can be achieved over a wide range, allowing the load-bearing module to be provided in a single size. Therefore, it is not necessary to stock the rod-like connection (especially aluminum rods) in different sizes / lengths.

[0032] According to one embodiment, the fastening unit has a transition piece or transition area between a base of the fastening unit and a rod-like, height-adjustable connection, advantageously with sleeve-like / socket-like receiving areas for the rod-like, height-adjustable connection. A change in material can advantageously be provided at the transition piece / area, in particular from (injection-molded) plastic (on the side of the orthosis) to metal and / or a composite material (i.e., at the height-adjustable connection, at the support brackets, and optionally also at the coupling components).

[0033] According to one embodiment, a height range on the back splint is predefined for attaching the load-bearing module. This height range lies above or below a height range defined for attaching the adapter, specifically as close as possible above or below the adapter, or within the adapter's range. This facilitates a comparatively low insertion / transfer of the load into the orthosis, thus minimizing forces acting high in the upper body with a large lever arm. This also promotes a very ergonomic carrying position for the load / unit / apron in a forward-bent posture, which can also proactively simplify daily operations, especially for surgeons.

[0034] According to one embodiment, at least two traction element sections acting on the shoulders are guided around a plurality of deflection elements in a center of force defined by the adapter, particularly in a pulley system, such that the at least two traction element sections acting on the shoulders can be operated together, with the adapter preferably being connected to the back splint in the region of the center of force. This also facilitates easy handling and operation of the orthosis (and also of the unit to be worn), particularly independently of other persons, solely by the wearer.

[0035] According to one embodiment, the adapter defines an end position for the respective shoulder strap corresponding to a maximum tightened position, in particular by the respective shoulder strap locking into the end position or at least being able to be positioned there in a form-fitting manner or by contacting it. This also facilitates maintaining a setting or length of the orthosis's shoulder straps that is particularly advantageous, especially when individually tailored.

[0036] According to one embodiment, the load-bearing module has a height- and length-adjustable adjustment and coupling range. This facilitates relatively simple and straightforward size adjustment, including in the vertical direction, for example, to accommodate torso lengths and / or loads or torso sizes of varying sizes. Such height adjustment or bridging also allows for a suitably low relative position of the load-bearing module on the backrest rail (either through design or individual adjustment), particularly with regard to positioning the mounting unit below or on top of the adapter. In other words, the load-bearing module is advantageously supported as low as possible on the backrest rail, for example, via an adapter provided on the backrest rail.Optionally, the load-bearing module can also have a telescopic rail, telescopic rod or similar means for height adjustment (i.e., adjustment without structural changes), particularly in the height / length variable adjustment and coupling area.

[0037] According to one embodiment, the back orthosis device is designed to support the load-bearing module below the thoracic kyphosis of the individual. This allows the (weight) force exerted by the unit being worn to be transferred particularly effectively and in a posture-friendly manner to the lower corset structure and especially to the pelvis. This also promotes a high level of wearing comfort over extended periods of use, e.g., several hours.

[0038] According to the invention, the load-bearing module has a freestanding, shoulder-spanning support unit, which includes two support brackets that project anteriorly / ventrally beyond the shoulders. These support brackets are advantageously integrally connected to a coupling part of the coupling device or at least permanently connected to each other. Optionally, the support unit can also be pre-connected to the respective unit to be supported (e.g., apron), for example, by being integrated into it (particularly for defining the relative position of the unit and the support brackets). In both embodiments, handling is further simplified, and safety is also increased.

[0039] According to one embodiment, the respective support bracket has one end fixed in the area of ​​a coupling part of a coupling device and a free end. The respective free end can also be tapered, which can facilitate connecting or coupling with the unit to be supported.

[0040] According to one embodiment, the support unit comprises a coupling part of the load-bearing module's coupling device, which can be connected to the back rail. This coupling part is particularly well integrated as a single piece, e.g., laminated in, or at least permanently bonded together. This also facilitates the integration of the load-bearing module into the object to be carried, e.g., an X-ray apron. The object, along with the attached support unit and one coupling part, can then be placed onto the other coupling part on the back rail in a comparatively simple and ergonomically optimized manner.

[0041] According to one embodiment, the respective support bracket has a flat cross-sectional geometry, i.e., it is wider than it is high / thick, in particular by a factor of at least 3, preferably by a factor of at least 4 or 5. This also enables good load distribution in combination with damping support of the unit to be carried, which can further improve ergonomics.

[0042] According to one embodiment, the respective support bracket consists of a fiber composite material or at least comprises one, in particular glass and / or carbon fibers. This provides a good compromise between weight and load-bearing capacity, especially in combination with damping support for the unit being carried. Alternatively, aluminum or steel can be used as the main material component; however, such a material composition has proven to be very expensive to manufacture.

[0043] According to one embodiment, a freestanding shoulder-spanning support unit of the load-bearing module has at least one support bracket, which is designed as a one-piece integral molded part or injection-molded part, in particular made of fiber composite material or plastic or of metal or of a hybrid material comprising at least one of these materials.

[0044] This facilitates, on the one hand, optimization with regard to robust structural design and load-bearing capacity, and on the other hand, the integration of the load-bearing module or its corresponding components into the unit to be supported, e.g., an X-ray apron. This also further simplifies handling. Manufacturing based on injection molding has proven particularly advantageous within the scope of the present invention in terms of a good compromise between effort and load-bearing capacity. For example, a plastic-glass fiber composite is used, e.g., polypropylene with a glass fiber content in the range of 25% to 35% (preferably by volume).

[0045] For example, at least the support brackets, e.g., the entire support unit, are manufactured from polyamide, particularly glass bead-filled, by laser sintering (e.g., the so-called SLS process). For example, the load design is based on a load in the range of 150 to 200 N (Newtons), especially a vertical load.

[0046] It is understandable that it has been shown that an injection molding manufacturing process can be used to optimize the strength, particularly of the support brackets, especially by predefining the method of material feed (or the insertion direction). Advantageously, the respective component (especially the support bracket) is injection molded in such a way that embedded fiber components (especially glass fibers) are aligned in the direction of the load.

[0047] According to one embodiment, the load-bearing module is Y-shaped when viewed in the sagittal plane, extending from the support brackets down to the mounting unit of the load-bearing module. In other words: In the area of ​​the mounting and coupling of the load-bearing module, the module is relatively slim and can therefore be easily and efficiently positioned behind the backrest rail in terms of width, while in the area of ​​the shoulder blades and shoulders, the load-bearing module extends over the shoulders and along both sides of the neck.

[0048] According to one embodiment, the back orthosis device can be coupled to a unit designed as an X-ray apron by means of the load-bearing module, specifically in the area of ​​a coupling device of the load-bearing module, advantageously by simply placing / attaching it. This facilitates particularly easy handling, for example, in daily clinical practice. The support unit of the load-bearing module can also be connected to the X-ray apron, so that a surgeon only needs to handle the X-ray apron to couple the load-bearing module to the back orthosis device.

[0049] According to one embodiment, the back orthosis device, in combination with the load-bearing module, is designed to support the load exerted by the unit in the (height) range or section below the middle thoracic vertebrae (or in the height range of the back brace corresponding to the height position of these thoracic vertebrae when the orthosis is worn as intended), namely Th10, Th11, Th12, or even further down the back brace, advantageously extending to the lumbar region, in particular L1, L2, L3, or even further down the back brace. This also promotes particularly effective relief of the upper body, for example, in connection with a forward-bent posture of the person wearing the unit and orthosis.

[0050] It is understood that the design according to the invention allows the thoracic region to bear no load whatsoever. Rather, the force exerted by the unit to be supported can be transferred, at least substantially, from the shoulders to the ilium (pelvic bone or iliac crests), thus effectively avoiding force transmission to the spine. At least theoretically, based on the present disclosure, it also appears feasible to apply the force in the lower lumbar region, particularly in combination with a continuous back brace, whereby the force can advantageously also be transferred to a pelvic belt. Based on the present disclosure, a person skilled in the art can further develop the back brace and the method of coupling / fastening the adapter and mounting unit, and optionally also the pelvic belt, individually for specific applications.

[0051] According to one embodiment, the height range for attaching the fastening unit coincides with the height range for attaching the adapter. This results in a good synergy of the functions achievable with the orthosis described here, particularly with regard to advantageous load distribution and minimized strain on the person wearing the orthosis and the unit.

[0052] According to one embodiment, the back orthosis device is designed to allow the unit to be worn, in combination with a support unit and its attached coupling part, to be removed from the load-bearing module by lifting the unit and thereby uncoupling it from the back brace. This also facilitates relatively simple handling without assistance from another person or additional technical aids, particularly in the period following a strenuous examination or treatment (in medical applications).

[0053] The load-bearing module of the modular back orthosis system according to the invention, with back orthosis device, has a support unit that supports the unit and can be arranged freely across the shoulders, which is advantageously manufactured by injection molding. In this respect, the back orthosis device of the modular back orthosis system according to the invention has a load-bearing module that includes a support unit that supports the unit and can be arranged freely across the shoulders, which can be manufactured by injection molding, wherein the support unit advantageously comprises a coupling part that can be attached to the back brace. This allows the aforementioned advantages to be realized, in particular with regard to the advantageous integration of the support unit into the respective unit to be worn, which also further simplifies handling.It is understandable that a support unit or at least support bracket manufactured by injection molding can also consist at least partially of GFRP or CFRP, especially since the fibers can be introduced in such a way as part of the injection molding process that a fiber composite can be realized, also section-specific, e.g. at least in the upper curved area of ​​the support brackets with a section-specific fiber density.

[0054] The aforementioned task is also solved by a load-bearing module designed for coupling a unit worn, for example, as personal protective equipment, with the back brace of a back orthosis device of a modular back orthosis system according to the invention, which is designed for height adjustment via the back brace. This allows the aforementioned advantages to be realized. The load-bearing module consists of three or at most four components: at least a support unit (shoulder bracket) that carries the unit, a fastening unit (connector) that ensures attachment to the back orthosis device, and a height- and length-adjustable adjustment and coupling area (aluminum rods). This can also ensure an advantageous compromise between variability / customizability and (manufacturing) effort.

[0055] The load-bearing module is advantageously manufactured by assembling or connecting three or at most four components: an injection-molded part (support unit) that carries the unit, a fastening unit that ensures attachment to the back orthosis device, and a height- and length-adjustable adjustment and coupling area (and optionally also a coupling part molded onto the support unit, in particular a pluggable support coupling part). Advantageously, the support unit, or at least one (respective) support bracket of the support unit, is injection-molded in such a way that embedded fiber components (in particular glass fibers) are aligned in the direction of the load.

[0056] Advantageously, the adjustment and coupling area connects both cranially and caudally to the support unit and the mounting unit in a plug-and-socket manner. The adjustment and coupling area can also provide at least one coupling element each (cranially and / or caudally) to form a coupling device together with the support unit and / or the mounting unit, for coupling / mounting the support unit (possibly with the load-bearing unit already attached to it). For example, the adjustment and coupling area has a (double-)rod-like connection which forms or provides a pluggable support coupling element on at least one side (cranially and / or caudally), for example, simply via free plug-like ends of the double-rod-like connection, which couple with socket-like recesses on the support bracket and / or the mounting unit.

[0057] The aforementioned problem is also solved by a unit, in particular an apron, to be worn as personal protective equipment, comprising a support unit of a load-bearing module of a back orthosis device of the modular back orthosis system according to the invention, attached / attachable thereto, wherein the support unit comprises a coupling part of a coupling device of the load-bearing module that can be coupled to the back splint, wherein the unit is configured for coupling with a back orthosis device of a modular back orthosis system according to the invention, wherein the coupling part is designed as a pluggable support coupling part, via which the unit can be uncoupled from the back splint for removal. This allows the aforementioned advantages to be realized. For example, support brackets of the support unit are permanently connected to the unit (e.g., X-ray apron) at least in the curved section spanning the shoulders.Advantageously, the support unit (especially the brackets) is permanently integrated into the apron by sewing, weaving, gluing, or similar methods, with the apron potentially featuring corresponding pockets for this purpose. Alternatively, a reversible fastening coupling, such as a screw connection, can be provided.

[0058] The aforementioned problem is also solved by a back rail of a back orthosis device of a modular back orthosis system according to the invention, having attachment points provided for supporting a load-bearing module attached / attachable thereto in corresponding attachment points, in particular in the area immediately above or below an (traction) adapter attached to the back rail or in the area of ​​the adapter (in particular attached to the dorsal outside of the adapter).

[0059] This allows the aforementioned advantages to be realized. For example, the load-bearing module can be put on and taken off by the person wearing the orthosis, either alone or coupled with the unit being carried, as needed.

[0060] Further advantageous aspects concerning the basic structure of a back orthosis device can be explained in accordance with the disclosure from WO 2023 / 098 936 A1, in particular also based on the findings described here from the further development of a modular concept with regard to a load-bearing module for a unit to be carried, starting from an advantageously modularly designed back orthosis device.

[0061] The modular back orthosis system according to the invention, with back orthosis device, comprises a hip belt connectable to the back splint, in particular a hip belt connected to the back splint by means of screw connections or similar force-fit / form-fit coupling means. This allows the load to be distributed even better and, in particular, also supported via the hips. It should be understood that a hip belt is not necessarily a required component of the back orthosis device, but, especially in the area of ​​comparatively large loads in the upper single-digit or even double-digit kilogram range, it can further reduce the loads acting on the back of the wearer, particularly under continuous load, and can therefore be / should be retrofitted in several applications.

[0062] The method of coupling between the back brace and the hip belt can advantageously be based on purely circular contact pressure and the resulting form-fit and / or force-fit. Form-fit is advantageously achieved by frame / side panels and a pad, which are advantageously directly connected to the back brace, e.g., by means of screw connections. The frame / side panels and corset components are connected or held together, e.g., by a loop, particularly for retention when unloaded.

[0063] The hip belt, for example, can also be attached to or connected to the back brace in a central area viewed from the front. Alternatively, a different type of belt than a hip belt can be provided on the back brace, in particular a belt that surrounds the person's upper body in a transverse plane, and to which, for example, at least one traction element or a corresponding section of traction element can be attached, e.g., by means of Velcro.

[0064] The inventive design of the back orthosis system is particularly suitable for use with a back orthosis device comprising a back splint resting against the spine, at least one shoulder strap, and at least one traction element section connectable to the back splint for adjusting the force exerted by the shoulder strap and back splint, which is guided via an adapter attached to the back splint, wherein the back orthosis device has a load-bearing module connectable to / connected to the back splint and projecting anteriorly / ventrally beyond the shoulders in the intended arrangement on the back splint for shoulder / back relief and is designed to transmit (gravitational) loads caused by a unit to be worn over the shoulder and / or neck into the back splint, wherein the back orthosis device has a fastening unit attached to the back splint.The load-bearing module supports the unit to be worn on the back splint, wherein the load-bearing module has a freestanding, shoulder-spanning support unit which has two support brackets that project anteriorly / ventrally beyond the shoulders, namely a back orthosis device of a back orthosis system according to the invention, wherein the load-bearing module is used to support a unit in the configuration of a (X-ray) apron. This allows the aforementioned advantages to be realized, particularly with regard to synergy effects in everyday clinical practice, especially with regard to preventive relief for surgeons.

[0065] The inventive design of the back orthosis system is particularly suitable for use with at least one support bracket of a support unit projecting freely forward (anterior / ventral) beyond the corresponding shoulder of a person, in combination with at least one coupling part connected thereto or provided integrally thereto, in particular a supporting plug-in coupling part with at least one male, e.g. pin-like, coupling section or a correspondingly corresponding female negative contour / shape, in particular with a coupling part designed for positive coupling by bearing on it, for providing a load-bearing module for supporting a unit used as personal protective equipment, such as, for example, a helmet.an X-ray apron, a (heat-protection) apron worn in a metalworking context, protective equipment worn in a disaster relief context, a comparatively heavy unit worn in front of the chest and / or abdomen (especially from three, four or five kilograms), or other apron-like personal protective equipment, each attached to a back brace of a back orthosis device located in the area of ​​the spine, especially at least in the area of ​​the thoracic vertebrae, particularly Th8 or lower, wherein the back orthosis device has a fastening unit attached to the back brace by means of which the unit to be worn is supported on the back brace, especially in the case of a back orthosis device described above. This allows the aforementioned advantages to be realized, especially with regard to the provision, integration, and use of the load-bearing module or...Components of the load-bearing module. This also facilitates application-specific customization. It should be understood that the reference described here, "in the region of the thoracic vertebra Th8 or lower," is to be understood as an example, and that a person skilled in the art can implement deviating arrangements based on this, particularly thanks to a back brace extending far across the back.

[0066] The inventive design of the back orthosis system is particularly suitable for use with a load-bearing module comprising at least a freestanding, shoulder-spanning support unit with at least one freestanding support bracket, a coupling device with at least two coupling parts, and a fastening unit attached / attachable to a back rail of a back orthosis device, namely a back orthosis device of a back orthosis system according to the invention, which rests in the area of ​​the spine, for providing the fastening unit with one of the coupling parts in an arrangement attached to the back rail and for providing a unit or load to be carried over the shoulder and / or neck (in particular personal protective equipment, e.g.(Medical apron) with an advantageously already attached support unit and one / the further coupling parts such that the unit to be worn is supported and secured by coupling (in particular by overlapping) the coupling parts via the fastening unit on the back rail, corresponding to the process of putting on, coupling and supporting a unit used as personal protective equipment, in particular an (X-ray) apron. This allows the aforementioned advantages to be realized, not least with regard to advantageous modularity, a wide range of applications and optimized ergonomics even when handled by only one person (namely the person wearing the back orthosis device and the person carrying the load).

[0067] The inventive design of the back orthosis system is particularly suitable for use with the inventive modular back orthosis system comprising a back orthosis device and a hip belt connected to the back orthosis device, in particular to a back splint of the back orthosis device, for supporting a unit, in particular an apron, which is suspended above the shoulder of a wearer by means of a load-bearing module of the back orthosis device and used as personal protective equipment. This allows the aforementioned advantages to be realized.

[0068] It is understood that the concept according to the invention is based on a modular system with a back brace, in which a hip belt is not necessarily provided. However, the inclusion of a hip belt is advantageous. If a hip belt is provided, the force transmission can optionally be achieved via the hip belt. Based on the present disclosure, the person skilled in the art can transfer the teaching described with reference to the back brace to a support system that also uses a hip belt, particularly since, due to the modular concept, the hip belt can also be connected to the back orthosis or its back brace.

[0069] Summary: Back braces enable an ergonomically and medically advantageous alignment of the spine, stabilizing it while also protecting against detrimental movement patterns. Back braces are typically worn by patients or individuals with corresponding conditions, primarily within the context of professional medical therapies. The present invention proposes a modular back brace system with a back brace device that, while maintaining the existing functionality, allows for functional integration or expansion with regard to load bearing, specifically for loads from personal protective equipment such as an X-ray apron. This is achieved in a modularly retrofittable manner, so that the same type of back brace device as before can be used for patients and now also for largely healthy individuals such as surgeons (especially in hospitals) or, for example,Actors from the field of disaster relief or, for example, skilled workers in the steel industry (especially for bearing the load when wearing heat protection aprons) can be provided and utilized, particularly for preventative purposes. This can also significantly simplify procurement logistics and improve the sustainability and usability of this type of back orthosis. BRIEF DESCRIPTION OF THE FIGURES

[0071] The invention will first be explained with general reference to all reference numerals and figures. Specific features or individual aspects, or aspects of the present invention that are clearly visible / representable in the respective figure, will be addressed individually in connection with that figure.

[0072] A back orthosis device 10 is provided for shoulder / back relief with respect to a unit to be worn, comprising a back rail 11 and at least one shoulder strap 13 and at least one traction element section guided in the area of ​​or in extension of the shoulder strap, which is preferably coupled / connectable to the back rail 11 and is operable for adjusting the force exerted by the shoulder strap and back rail, in particular on the back, and is guided via an adapter 20 preferably attached / attachable to the back rail; wherein the back orthosis device has a load-bearing module 70 connectable / connected to the back rail for shoulder / back relief and is designed to transfer loads caused by a unit worn over the shoulder and / or neck into the back rail 11, in particular when the unit is arranged suspended over the shoulders.

[0073] The load-bearing module 70 is advantageously formed by only three or four components: a support unit 60 carrying the unit 80, a fastening unit 40 ensuring attachment to the back orthosis device, and a coupling device 50 or a height- and length-adjustable coupling area 42. The entire load-bearing module 70 can be modularly coupled to the back orthosis device by means of the fastening unit 40, in particular at several attachment points 41, e.g., screw connection points. Attachment can be made, for example, directly to the back rail or also by means of the adapter 20. Accordingly, at least one attachment point 11.5 is provided on the back rail 11 and / or on the adapter 20 for attaching and supporting the load-bearing module 70.The fastening is therefore advantageously carried out in combination with fastening means 46 acting between the fastening unit and the back rail, in particular by means of screws.

[0074] Advantageously, a height- and length-variable adjustment and coupling area 42 is provided between the fastening points and the support unit 60. Depending on the selected composition and material, this area can be provided either by the fastening unit 40 or by the coupling device (or coupling module). Advantageously, the height adjustability is ensured by at least one rod-like, height- and length-variable connection 43, and particularly advantageously by a double-rod arrangement that is as torsionally rigid as possible. This arrangement extends between a transition piece or transition area 44 of a base 45 (especially in the form of a tab or plate) of the fastening unit 40 on the one hand, and a coupling part 51 of the coupling device on the other. The base 45 has a ventrally oriented underside 45a, which is optionally mounted on the back rail or directly on the adapter.

[0075] The coupling device 50 (or the coupling module) advantageously comprises a first coupling part 51 (in particular a pluggable support coupling part), a first coupling section 51.1 (in particular male), first retaining means 51.3, a second coupling part 52 (in particular a pluggable support coupling part), a second coupling section 52.1 (in particular female), and second retaining means 52.3. The retaining means can, for example, be magnetic. The first / second coupling sections can interact in a manner similar to a plug-socket connection, advantageously at least substantially in a positive-locking manner. The retaining means can also facilitate the coupling process, in particular by making it easier to search for and locate the coupling partners.The coupling device 50 enables simple (even blind) coupling of the support unit 60 with the already attached fastening unit 40, whereby the support unit 60 can also already be connected to the unit 80 to be carried. In other words: When using the load-bearing module described here, coupling can be performed in the area of ​​the coupling device 50 when attaching or detaching the unit to be carried, without the need to make or disconnect any further connections. This can advantageously be done entirely without assistance from another person, i.e., solely by the person (with their back to the load or overhead) who has to carry the unit to be carried.

[0076] The freestanding, shoulder-spanning support unit 60 (or support module) advantageously comprises two advantageously injection-molded, freestanding support brackets 61, each with a bracket end 61.1 attached to the coupling device 50 and a free bracket end 61.2. Between the bracket ends, in the intended arrangement above each shoulder side, a freely swinging, elastically pre-tensioned bracket section 62 is formed, with a curved section 62.1 spanning the corresponding shoulder. The elastic and strength properties, particularly in this area, can be predefined by specifying the fiber direction and density, especially within the framework of an injection molding process. By means of the support unit 60, coupling device 50, and fastening unit 40, the load-bearing module 70 is particularly advantageously designed to optimize shoulder / back relief and force transmission into the back rail 11.Each unit 80 or load (especially protective equipment), e.g., a medical apron, particularly an X-ray apron, worn over the shoulders and / or neck, can therefore be supported on the back rail 11 by means of the fastening unit 40, whereby the force flow path can be directed from the brackets 61 via the bearing surfaces formed between the support unit 60 and the coupling device 50 or fastening unit 40, and optionally also via the adapter 20 into the back rail 11. Thus, a modular back orthosis system 100 with back orthosis device 10 and load-bearing module 70 is provided, to which the load-bearing module 70 can be added depending on the application / situation, optionally in combination with a hip belt 30.

[0077] The present disclosure shows that the force flow from the unit 80 to the orthosis 10 should be transmitted as low as possible in the body. The present invention provides, in particular, two height ranges, depending on the desired modularity and the configuration of the adapter 20: a first height range z1 of the back rail 11 for attaching the fastening unit 40 is located slightly above a second height range z2 of the back rail for attaching the (reclination) adapter 20. According to one embodiment, the height range for attaching the fastening unit 40 coincides with the height range for attaching the adapter, especially when the fastening unit 40 is supported by the adapter.

[0078] The use of the components of the modular back orthosis system according to the invention can also be described as follows: In a first step S1, the back orthosis device is applied; then, in a second step S2, the shoulder straps and optionally a pelvic strap are adjusted; details of these first two steps can also be found in publication WO 2023 / 098 936 A1. In a third step S3, the unit to be worn (e.g., apron) is applied / coupled, in particular by coupling the support unit with its integrated coupling part to the fastening unit already supported on the back splint (e.g., placing an X-ray apron over the head). In other words: The support unit can be pre-connected (permanently, by the manufacturer) to the unit 80 to be worn. All these steps can be carried out independently by the person who is to wear the orthosis and the unit.Between steps S1, S2, S3 and also after any subsequent steps Si (e.g. medical activity in connection with an X-ray apron 80), a manual personal readjustment or similar individualization measure on the orthosis system 100 can be carried out by the person wearing the unit, which is in . Fig. 7 is identified by the reference number R1. The double arrows between steps S1, S2, S3 indicate that the sequence is reversible, i.e., unloading can be accomplished by steps S3, S2, S1. To unload the unit to be carried, it can be lifted in combination with the support unit and the coupling part formed on it, thereby uncoupling it from the back rail.

[0079] The back orthosis device 10 can be designed as follows: The back orthosis device 10 has a back splint 11 with rib-like recesses 11.1 and a shoulder strap 13 with a right shoulder strap section and a left shoulder strap section. A dimensionally stable coupling section 13.3 is provided at the free end 13.1 of each shoulder strap section (in particular with a fastening pull tab). Optionally, a length adjustment mechanism for the respective shoulder strap section can be provided in / on the coupling section; alternatively, length adjustment is deliberately provided only in the shoulder area (in particular by means of so-called Y-shaped Velcro connections).The two shoulder strap sections can be operated by means of a traction element guided by a centrally arranged centering unit 20 (also referred to here as an adapter). This unit centers the traction force and distributes it as symmetrically as possible between the shoulder strap sections. A corresponding traction element section is provided for each shoulder strap section. Within the centering unit 20, the traction element is guided over several deflection pulleys, and a deflection pulley is also preferably provided at the respective coupling section or free end 13.1. Thus, the centering unit 20 can also provide force amplification based on a pulley system.Preferably, the two traction element sections are combined and attached to each other in a control unit; the centering unit 20 can therefore provide a circumferential traction element by means of which, with comparatively little effort and applied unilaterally, a central symmetrical force distribution and transmission to both shoulder strap sections can be ensured. The control unit can be attached, for example, to a side panel or a (hip) strap 30 or similar lateral component of the orthosis or a modular (back) orthosis system 100, e.g. by means of a hook and loop fastener.

[0080] A person 1 can put on the device 10, particularly in the manner of a backpack; for this purpose, the shoulder strap sections can be released relatively far; the circumferential design of the traction element allows for a wide opening through which the patient's arm must pass; thus, putting on and taking off the orthosis 10 can be facilitated and accelerated even without uncoupling straps. The strap sections can then be pulled centrally by means of the control unit into the desired or predefined position up to the centering unit 20 (stop position), so that a predefinable reclining / reclination effect is achieved on the shoulders of person 1. The traction force centering unit can therefore also be referred to as a reclination adapter 20 in connection with such an application.The relative dimensions and the relative arrangement of a force center defined by the centering unit can be adjusted by means of a height adjustment 11.3 (in particular rail or guide) on the back rail 11, if necessary; for this purpose, different types of coupling or fastening means 25 can be provided between the tensile force centering unit 20 and the back rail 11, e.g. screw connections and / or T-nuts or similar countermeasures.

[0081] To improve / facilitate the adjustment of the orthosis 10, the centering unit 20 preferably has a stop 23 for the shoulder strap 13, by means of which a parking position or a kind of positive locking end position can be defined. This also has the advantage that the orthosis only needs to be adjusted once for the respective patient by a doctor, medical assistant, therapist, or orthotist (in particular, correctly adjusting the length of the shoulder strap sections), and then the patient 1 can use the control element to tighten the shoulder strap sections centrally and symmetrically and position them to the end position; thus, excessive pulling of the straps can be avoided; for example, it can be prevented that the patient accidentally sets an excessive extension effect.

[0082] The following (anatomical) directional references may facilitate understanding, particularly with regard to the application of device 10, where the centrally running sagittal plane is marked by the reference symbol (xy): anterior (ventral) a; posterior (dorsal) d; inferior (distal, caudal) u;

[0083] The following section explains special features of the invention with reference to individual figures or embodiments.

[0084] In the Fig. Figure 1 illustrates a load-bearing module with a coupling device designed as a support plug-in coupling. One coupling part is connected to the fastening unit, and the other coupling part is connected to the support unit, advantageously integrally as a single piece. The fastening unit is designed for coupling with the back rail of the orthosis. Fig. 1A The Y-shape of the load-bearing module is recognizable, defined in particular by the shape of the support brackets of the support unit. Fig. 1B shows that, apart from the support brackets which (as intended) extend forward over the shoulders, the load-bearing module extends essentially in one plane, namely, when supported as intended on the back rail (not shown), at least approximately in a frontal plane or at most slightly tilted backward (posterior / dorsal) relative to it. Fig. 1C shows this even more clearly.

[0085] In the Fig. Section 2 describes an embodiment in which the fastening unit is designed to couple with the back rail of the orthosis. Fig. 2A indicates the arrangement of the fastening unit directly above the height position of the adapter and above the guide for the shoulder straps. Fig. 2B shows the shoulder-spanning arrangement of the support brackets. The support unit (and thus also the unit to be carried) can be detached from the fastening unit attached to the back rail in the manner of a plug-in coupling. Fig. 2C highlights the respective height range z1, z2 for coupling / attaching the adapter and mounting unit to the back rail.

[0086] In Fig. Figure 3 describes an embodiment in which the fastening unit is set up for coupling with an adapter of the orthosis, by means of which indirect coupling or fastening to the back rail takes place.

[0087] In the Fig. Section 4 describes an embodiment in which the fastening unit is designed for coupling with an adapter of the orthosis, by means of which indirect coupling or fastening to the back splint is achieved. The base of the fastening unit has a bottom surface that rests directly on the adapter and is advantageously geometrically designed to correspond to its top surface, for a kind of positive-locking coupling effect. Fig. 4A shows the coupled / fastened arrangement. Fig. 4B highlights the height section z1, z2 of the attachment, which coincides in this embodiment and is advantageously arranged in a low position, more or less directly above the effective area of ​​the hip belt. Fig. 4C schematically illustrates a / the load-bearing unit 80 connected to the load-bearing module, here in the form of a (X-ray) skirt.

[0088] Especially from the Fig. 2 and Fig. As shown in Figure 4, the support unit can include the coupling part of the load-bearing module's coupling device, which can be attached to the back rail, advantageously in a one-piece integral design, e.g., laminated in, or at least in a design that is already permanently connected. This can facilitate the provision of these components of the load-bearing module in conjunction with the respective unit to be supported, as well as their handling.

[0089] In Fig. Figure 5 shows the back orthosis system 100 with hip belt and load-bearing module 70 in use in combination with an X-ray apron 80.

[0090] In Fig. Figure 6 shows the load-bearing module 70, equipped for the back orthosis device described here, with its support unit already attached to the unit 80 to be worn (here: X-ray apron).

[0091] In Fig.The following seven steps illustrate the procedure for applying the back orthosis and supporting the respective load or unit: The individual applies the back orthosis (step S1) and adjusts the shoulder strap(s) and optionally a pelvic strap (step S2). The unit to be worn (e.g., apron) is then attached by connecting the support unit to the load-bearing module's coupling (step S3), specifically by placing / inserting it onto the support. Steps S2 or S3 may be followed by subsequent steps Si, such as medical examinations. Individual adjustments / readjustments can be made between each step, if desired.
