Description
Technical field
The present invention relates to a kind of for preventing the orthopedics of the excess pressure load on pressure-sensitive vola.Especially, but absolutely not exclusively, this orthopedics can be used for the treatment of diabetic.Footwear according to the present invention are generally suitable for treating pressure-sensitive vola.But, for diabetic, prevent the excess pressure load on foot to have significant therapeutic meaning.
Background technology
On average have the people of 1/5th need treatment vein problems or suffer from the Lesion of vein causing illness in age group between 20 and 70 years old, therefore, treatment becomes necessary.To the larger reduction often of this explanation normally connective tissue, this causes the reduction of wall of vein, and therefore causes venous valve not exclusively closed.This causes the venous return from both legs to health to reduce.
Only in Germany, just have the diabetic of about 5,000,000, wherein, so-called diabetes is so that almost significantly mode is popular.Therefore, this means to form open wound on the vola of forefoot, this open wound is often infected, and comes to an end mainly with foot amputations greatly.The reason producing diabetes is: cause due to the metabolism status of diabetic in arterial vascular system and occur compared with main artery and the narrow and possible obstruction compared with parteriole capillary.Therefore, tissue, particularly skin do not resupply enough oxygen and partly necrosis, thus produce the fracture area of skin.Especially, due to arteriocapillary miopragia, cutaneous nerve no longer suitably supplies, and produces diabetic peripheral neuropathy with integrated.This means that patient loses sensitiveness in the malnutritive region of skin, with the sensitiveness significantly reduced pain, make the pressure point anatomically predicted no longer clear and definite, and skin can sustain damage when not causing pain substantially.Due to the pain in the region of the imperceptible skin overstrain of patient, therefore usually note the damage less than skin completely, in any case or just can notice all very late.
Known a kind of footwear with rigid sole and convexity sole part from DE 10 2,010 022 329 A1, these footwear are the types that can be worn by diabetic especially.In order to be fixed in footwear by foot, in common footwear, particularly heel area is fixing particularly important, because foot does not substantially roll due to the rigidity of sole during walking.On the contrary, footwear roll on circular sole part, and when walking forward, the rear portion of sole must be lifted relative to the rolling point below forefoot.When the rear portion of sole is lifted by this way, sizable masterpiece is used between the immobilising device of footwear and foot, rocks in footwear to stop heel.This in footwear of heel rocks the undesirable relative motion that will foot caused relative to sole medial surface, and this relative motion may cause damage and wound.
In order to be fixed in footwear by heel, DE 10 2,010 022 329 A1 proposes a kind of Y-Shaped insert, and the bottom of this insert is attached to sole, and the Liang Ge top set one of this insert strides across heel, and another strides across instep.This Y-Shaped immobilising device has confirmed to be not suitable for foot to be as far as possible seamlessly fixed in footwear.Especially, this is because: when tightening up immobilising device, do not have the enough pressure that tightens up can be applied to heel area and make heel start slightly to rock in footwear.If the support pressure excessively increased in instep region to compensate the pressure of the deficiency in heel area, then reduces wearing comfort, and may produce undesirable hyperemia.

Footwear according to the present invention are based on such theory: immobilising device comprises the heel band that the rear portion striding across calcaneum from left foot face extends to right crus of diaphragm face, also comprises and extends across instep and have the DLZ pulling device.Teaching according to the present invention provides: DLZ is attached to left part and the right part of heel band in the mode of carrying out load transfer with left Connection Element and right Connection Element, Connection Element is separately apart from two end one segment distances be arranged laterally on footwear of heel band, and central part one segment distance across calcaneum of distance heel band.By means of such immobilising device, heel can be fixed in optimal manner the sole according to footwear of the present invention.This is because when by DLZ pull device to strain for size adjusting time, tightening force is passed to two parts of heel band in the mode that Connection Element sentences load transfer.Because two ends of heel band are attached to footwear, the tightening force being therefore passed to heel band at Connection Element place produces pulling force to act on the central part across calcaneum of heel band.Therefore, heel band acts on around heel in the mode of form fit self, and is fixed in footwear by heel by form fit.The tightening force being acted on heel by heel band can be adjusted by the tightening force pulling device to apply by changing by user.Because the tensioning function of this form fit between heel band and the heel of user is adjustable, so set best cooperation, this prevents heel from skidding off relative to sole.Therefore, when going ahead, heel also remains fixed in footwear in gapless mode substantially during rigid sole rolls, and the undesirable relative motion in vola and footwear is minimized at the end or stop this relative motion completely.
Be arranged in pull transfer to the layout of two ends be fixed on footwear relative to side direction of the central part across calcaneum relative to heel band of residing two Connection Elements of heel band and heel band to be significant with regard to the optimum apjustment of the cooperation of heel area with regard to footwear.This is because mechanical lever ratio and pull to follow than (pulling ratio) and change according to the layout of described two Connection Elements on heel band.About this point, proved that following is particularly advantageous: on the direction of the longitudinal axis of footwear, the side direction of the central part across calcaneum and heel band that Connection Element is all arranged in heel band is separately attached between two ends of footwear.In other words, this means: when laterally profile observes footwear, Connection Element is arranged between the rear portion of heel and two attachment point of heel band.Heel band can extend with straight line or slightly bending mode between two attachment point and the central part across calcaneum of heel band.By Connection Element being arranged between the central part of heel band and the end of heel band, device achieves: when will be pulled to strain, the direction of two Connection Elements of two of heel band sidepieces along instep is pulled out its straight line or omits bending shape by heel band, and in doing so, due to pull than and lever ratio, can when pull device applies relatively low adjustment power, at heel band, place applies high attachment forces.For user, this means high ease for use because he/her only need DLZ pull device place apply relatively low power come tightening of shoe with band.
As previously mentioned, when pulling device to strain, the direction of two of heel band sidepieces together and along instep upwards being pulled, therefore, the central part of heel band is strained forward along toe direction.This adjustment motion of heel band makes heel band slightly relatively rotate around the abutment in the attachment point region on two lateral ends of heel band.In the enough resilient situation of supposition material, this rotation is slightly compensated by the distortion of heel band in attachment point region.But in this case, user must apply extra tightening force to make heel band in the region Elastic distortion of two attachment point.Therefore, in order to avoid this extra tightening force, particularly advantageously, two ends of heel band are attached to sole in the mode of trunnion bearing.For this reason, such as, two ends of heel band can be riveted to sole with fixing rivet.Trunnion bearing allows the end of heel band to rotate in the mode do not stressed substantially around attachment point, and wherein, meanwhile, necessary tightening force is passed to sole by trunnion bearing.
Footwear system according to footwear of the present invention is intended to foot to be fixed on the sole of footwear.For this reason, the footwear system of footwear at least wraps up the top side face of foot in the mode of segmentation.Such as, footwear system can be made up of various band, therefore forms a kind of open footwear, such as sandals.Alternatively or extraly, footwear system can comprise the shell be made up of the upper material of softness.Described upper material can be synthetic material or the leather of such as Gore-Tex textile material.So upper material at least covers foot in the mode of segmentation, and adds snugness of fit.For footwear according to the present invention, provide heel band about this point and extend in the outside of shell.
If footwear according to the present invention are equipped with the shell be made up of the upper material of softness, then advantageously, be not connected to shell in the left part of heel band between two ends being arranged laterally on footwear of the central part across calcaneum of heel band and heel band and right part but freely extend across soft upper material alternatively.Due to the fact that heel band and shell are not connected to each other, are not particularly sewed together, so when by DLZ pull device to strain time, heel band can freely be repositioned to the upper material striding across shell, although make to have adjusted heel band, upper material is still indeformable, thus avoids the formation of gauffer.
In addition, particularly advantageously, the central part across calcaneum of heel band is not also connected to the shell be made up of the upper material of softness.Therefore, heel band is then only directly connected to footwear two ends, is particularly connected to sole.The every other part of heel band freely can be repositioned to the flexible upper material striding across shell, and therefore heel band with realize optimum shape between heel and coordinate.In order to the central part of fixing heel band in heel area relative to the height of shell, shell is provided with the tab portion protruded upward.Then heel band extends across the attachment area of the tab portion protruded upward, thus stops heel band to gliding too far away.
In order to easily transmit required power in the heel band of footwear according to the present invention, heel band should use the mechanically sufficiently rigid manufacture of materials of the plastics garter spring of such as suitable thickness and so on.But, this heel band be made up of the material strengthening hardness has following shortcoming: during heel band is strained, heel band shows larger resistance, because rigid material must elastic deformation at least slightly in the abutment of Connection Element to its distortion in the abutment of two Connection Elements.In order to avoid these undesirable reaction forces---this reaction force is out of shape necessary in the dot area of two Connection Elements for heel band, particularly advantageously, there is material weakenings in heel band, this material weakenings is particularly in wedge-shaped indentation in the dot area of two Connection Elements.By means of this material weakenings, in the dot area of two Connection Elements, the hardness of heel band can reduce transverse to its longitudinal axis, thus reduces the resistance of heel band to the distortion during the tension of heel band.
The footwear sole construction of orthopedics is optional substantially, if generally sole has enough rigidity and therefore when going ahead the motion of foot be no more than tolerable degree.Except required rigidity, in order to high walking comfort can be guaranteed, advantageously, sole comprises the external sole and inner sole be made up of different materials.External sole then available a kind of elastic damping material is produced, to realize the walking comfort of wishing.Inner sole rigid material is produced.The rigidity of inner sole then may be selected to be enough high, and does not need to consider external sole material, because sole generally has use necessary rigidity on orthopedics.
Many users only need to use orthopedics on a foot, because second foot does not have pathology.But this fact greatly increases required production cost, because user only needs footwear, but producer has to not only provide the footwear of different footwear code for left foot but also for right crus of diaphragm.In order to required kind quantity and adjoint production cost can be reduced, therefore, advantageously, the medial surface towards foot of sole and footwear system is axially symmetrical about the longitudinal axis of footwear.Footwear can be through on left foot or on right crus of diaphragm by this axial symmetry of footwear medial surface alternatively.In order to supply different users, all requirements are then to provide the footwear of different footwear code, and footwear then can be worn on left foot or right crus of diaphragm alternatively.
Footwear according to the present invention are fixed on the pin of user by pulling device, and this pulls the type of device to be optional substantially.Preferably, device is pulled can be formed with the form of puller strap.Described puller strap is fixed on the side of DLZ by an end and anchor portion.Be attached with deflection ring in the opposite side of DLZ, puller strap can deflect from its anchor portion in this deflection ring, and in this case, puller strap with transformable length across instep.The free end of puller strap is provided with hook-type band or endless belt, and along with the adjustment of taut length needed for puller strap, this hook-type band or endless belt are placed in and are arranged on hook-type band in anchor portion region or endless belt, and are therefore fixed.
If footwear according to the present invention are designed to axially symmetrical and can be worn in alternatively on left foot or right crus of diaphragm, then particularly advantageously, the anchor portion of puller strap and deflection ring are fixed by corresponding coupling device in a detachable fashion.By being alternately separated the coupling device on anchor portion and deflection ring, the right side of stiff end at footwear or the layout in left side can be changed.Therefore, by two coupling devices of again planting, under all situations of axial symmetric design not considering footwear, the free end of puller strap advancing from inner side to outside can be provided.In other words, this means: by the coupling device of puller strap of again planting, be adjustablely made into following effect: slippers can be worn on left foot or right crus of diaphragm.
In order to be fixed in adjustment region large as far as possible by pulling the hook-type band of device, advantageously, the hook-type band of the loop fasteners in the anchor portion of puller strap or endless belt cover the outside be associated with anchor portion of coupling device.
Can preferably combine with orthopedic inner sole according to footwear of the present invention.Preferably, inner sole has the liner in region pressure peak be distributed in the space between the top side face and bottom side of inner sole namely under front podarthrum, the deformable gasket cover of described liner is filled with deformable obturator, and this obturator can relative to each other move.There is deformable gasket cover and be included in wherein can relative to each other be out of shape and the shape of this liner permission liner of obturator of movement is suitable for the change shape of vola in front foot joint area all the time.This is because the shape of liner is determined by the layout of the moveable obturator in insert.If now shape or the vola position in inner sole in vola changes, then by the displacement of transportable obturator, the shape of liner can easily be adapted to this change.The shift duration of obturator completes pressure compensation until realize major part.In other words, this means: obturator is shifted in insert until the shape of liner is applicable to the shape in vola again best, and therefore, major part dispersion or all pressure peaks eliminated completely between vola and inner sole.Wearing in the process of inner sole subsequently, the deformability of obturator, more precisely the deformability of insert provides best damping action.The displacement to a certain extent of obturator in insert also produces a kind of massage motion of inner sole on the skin of vola, and this massage motion stimulates circulation.For the open area on the vola skin eliminating diabetic, this also serves positive role.
In order to the shape making the liner being filled with removable obturator can be suitable for vola in the mode of optimum shape, require in insert, do not have air pocket to be formed.This air pocket will move in insert according to pressure loading, and therefore constantly will change pressure state and produce undesirable pressure peak.Therefore, according to the preferred embodiment according to inner sole of the present invention, propose a kind of insert, it has at least one exhaust outlet, and when the pressure is exerted, the gas existed in insert escapes to outside by this exhaust port.Therefore, exhaust outlet is guaranteed to produce pressure compensation completely between and ambient atmosphere inner at insert.Thus avoid the undesirable air pocket of formation in insert.
In order to the shape of the liner of obturator at least temporarily fixedly can be filled with, insert can be provided with discharger.By means of this discharger, the gas existed can be discharged into the degree forming negative pressure in insert in insert.This negative pressure is revolted deformable obturator and pulls deformable gasket cover, and therefore fixes the relative position between each obturator.By making discharger ventilate, negative pressure can discharge in insert, and by the gasket shapes of the adjustable renewing of the displacement of obturator in insert.
Based on obturator displacement under a load by the adjustment of displacement to the shape of inner sole of the removable obturator existed in insert.In this process, the obturator in high-pressure area is displaced in area of low pressure, until all region lists in vola reveal pressure loading similar substantially.Due to metaplasia and the corresponding adjoint pressure loading in vola, the displaced path grown very much may be there is in the displacement of obturator, this obturator no longer can be advanced within the rational time.Especially, if whole vola is supported by single insert and the removable obturator be included in wherein, then may there is the displaced path grown very much, thus can not expect that liner is again formed in rational time range.In order to avoid the displaced path of unacceptable length and zones of different in order to the geometry of liner can be made to be adapted to vola especially, particularly advantageously, liner is divided at least two liner sections.So the shape of each liner section and the filling extent of particularly each liner section can be suitable for the requirement different separately in the zones of different in vola.
The quantity of liner section and the plantar region being furnished with liner section are optional substantially.A kind of liner section is provided according to favourable embodiment, on the one hand, this liner section is furnished with liner section in mode according to the present invention in the front foot joint area of foot and/or the toe areas at foot and/or the metatarsal at foot and anklebone region and/or the heel area at foot.Especially, the embodiment scheme altogether having four liner sections in toe areas and front foot joint area and metatarsal and anklebone region and heel area is particularly advantageous.
In the walking movement process of the user of orthopedic inner sole, inner sole produces rolling movement in footwear.The rolling movement of this inner sole may cause the undesirable translocation of obturator in insert.In order to these undesirable displacements are reduced to minimum, advantageously, between adjacent pad section, be furnished with interval trough.In the process of walking, when inner sole is rolled, described interval trough allows the relative motion of adjacent pad section, and therefore the translocation on the removable obturator in each liner section is reduced to minimum.
With regard to undesirable translocation of being caused by the rolling movement of inner sole most probable minimizes, advantageously, the interval trough between adjacent pad section extends along its longitudinal axis with bending shape.The curve of bending interval trough should be extend with the heel of the mode of indent around inner sole, and therefore points to forefoot direction with its core.
If inner sole has several liner section, so it is desirable that such as make obturator advance erratically between each liner section, thus the filling extent of each liner section may can be changed.In this way, the characteristic of inner sole is made to be suitable for the requirement of different users especially possibly.In order to realize this adaptability according to inner sole of the present invention, propose according to preferred embodiment: liner section is formed as being communicated with at least in part, gas and/or obturator can be walked between two liner sections be communicated with by least one passway.By making obturator be shifted by passway, the filling extent of each liner section can carry out changing or changing.In addition, gas is carried between each liner section by passage, makes not to be that each liner section must have exhaust outlet and/or discharger especially.
In order to avoid obturator to be shifted between the liner section be communicated with in the process using inner sole, particularly advantageously, relative to the cross section of the cross section suitably selector channel mouth of obturator.The cross section of passway should be at least enough large to make obturator be walked between the liner section be communicated with by passway under non-stress state for the cross section of obturator.Meanwhile, the cross section of passway should be enough little of relative to the cross section of obturator to make obturator not be shifted by passway under inner sole bears load condition.
In order to provide snugness of fit and the transformation particularly as far as possible without pressure peak in interval trough region, advantageously, extra elastic pressure distribution synusia is arranged in the side towards foot of inner sole, especially, this elastic pressure distribution layer is made up of foamed material.Because this extra pressure distribution synusia only needs to cushion little pressure peak, therefore it can be formed as relative thin, and can not suffer the undesirable impression in the wear trace that produces in addition and adjoint inner sole.
