Understøtningsapparat til forebyggelse af liggesår 5 Den kendte teknikSleeper Prevention Device 5 The Prior Art
Den foreliggende opfindelse angår et understøtningsapparat til forebyggelse af liggesår.The present invention relates to a support device for the prevention of bedsores.
10 Til forebyggelse og behandling af decubitus, som især rammer personer, som på grund af et handicap må sidde eller ligge mere eller mindre passivt, er det forsøgt at afhjælpe de gener, som er forbundet hermed.10 For the prevention and treatment of decubitus, which particularly affects persons who, due to a disability, must sit or lie more or less passively, attempts have been made to remedy the genes associated with it.
Den mest almindelige behandling består i brugen af puder eller underlag, 15 som er i stand til at fordele kroppens tryk mod underlaget. Dette kan gøres ved hjælp af mere eller mindre viskose fyldningsmidler.The most common treatment consists of the use of pillows or substrates, 15 which are capable of distributing body pressure against the substrate. This can be done using more or less viscous fillers.
Effekten er imidlertid af ’passiv’ art uden en aktiv påvirkning af kroppen til fremme af blodcirkulationen.However, the effect is of a 'passive' nature without an active influence on the body to promote blood circulation.
2020
Fra GB 1 540 336 kendes et apparat med aktivering i understøtningen i form af understøtningslegemer, som skiftevis hæves og sænkes. Dette skulle fremme blodstrømningen og dermed modvirke decubitus samtidig med, at det medfører en bekvem understøtning af kroppen.From GB 1 540 336 an apparatus with activation in the support is known in the form of support bodies which are alternately raised and lowered. This should promote blood flow and thus counteract the decubitus while providing convenient support for the body.
25 I praksis har det imidlertid ikke fungeret tilfredsstillende, da blodstrømningen ikke er kontrolleret i tilstrækkelig grad, men alene sker ved at en understøtning bevæges op eller ned, hvorved blod bliver presset sammen og strømmer til det nærmeste område, hvor en understøtning sænkes. Dette 30 vil medføre, at blodstrømningen bliver tilfældig og uregelmæssig og dermed ubekvem for personen, især sådanne som allerede har udviklet decubitus, ligesom det ikke fungerer mod afhjælpning heraf.25 In practice, however, it has not worked satisfactorily, as blood flow is not adequately controlled, but only by a support being moved up or down, thereby compressing blood and flowing to the nearest area where a support is being lowered. This will cause the blood flow to become random and irregular and thus inconvenient for the person, especially those who have already developed decubitus, and it will not work against its remedy.
DK 177100 B1 2DK 177100 B1 2
Formålet med opfindelsenThe object of the invention
Det er formålet med opfindelsen at afhjælpe disse mangler og ulemper, og 5 dette opnås ifølge opfindelsen ved hjælp af et apparat, hvor understøtningen omfatter et antal cylindre, som er indbyrdes hydraulisk forbundet således, at når en af trykpladerne sænkes, hæves en hosliggende trykplade således, at blodstrømningen kan styres i en ønsket retning.The object of the invention is to overcome these shortcomings and disadvantages, and this is achieved according to the invention by means of an apparatus in which the support comprises a number of cylinders which are hydraulically interconnected so that when one of the pressure plates is lowered, an adjacent pressure plate is raised thus that the blood flow can be controlled in a desired direction.
10 På denne overraskende enkle måde bliver blodstrømningen i kroppen ikke en tilfældig udsivning eller ophobning af blod, men en fuldstændig kontrolleret strømning fra et understøtningspunkt, hvor understøtningen hæves og til et hosliggende understøtningspunkt, hvis understøtning samtidig sænkes 15 således, at der opstår et ’lukket’ blodkredsløb fra cylinderen, der hæves, til en hosliggende cylinder, som sænkes.10 In this surprisingly simple way, the blood flow in the body does not become a random leakage or accumulation of blood, but a completely controlled flow from a support point where the support is raised and to an adjacent support point whose support is simultaneously lowered so that a closed 'blood circulation from the raised cylinder to an adjacent cylinder which is lowered.
Herved sikres en helt naturlig blodstrømning og dermed en understøtning af den i kroppen naturlige blodstrømning til og fra hjertet. Denne 20 blodstrømning kan effektivt kurere decubitus og tillige være en stor behagelighed for personer, som ikke selv kan sikre blodstrømningen i kroppen ved bevægelse på understøtningen. Ved at de samvirkende understøtninger placeres tæt ved hinanden, vil blodet let kunne flyde mellem punkterne uden nogen form for pres og dermed uden smerte.This ensures a completely natural blood flow and thus a support for the natural blood flow to and from the heart. This blood flow can effectively cure the decubitus and also a great comfort for people who cannot self-ensure blood flow in the body by movement on the support. By placing the cooperating supports close together, the blood can easily flow between the points without any pressure and thus without pain.

Ved, som omhandlet i krav 2, at udforme en understøtning i form af zoner med mange understøtninger opnås en helt jævn taktmæssig bevægelse af understøtningerne, hvorved der sikres en fuldstændig jævn blodstrømning i de dele af kroppen, som hviler på understøtningen.By providing a support in the form of zones with many supports, as provided in claim 2, a very smooth tactile movement of the supports is achieved, thereby ensuring a complete smooth blood flow in the parts of the body resting on the support.
Ved, som omhandlet i krav 3, at sikre styringen ved hjælp af en ventil, som 30 3 DK 177100 B1 med en given cyklus kan lede hydraulikvæske til og fra de aktiverede cylindre, opnås en driftsikker og hensigtsmæssig styring.By providing, as defined in claim 3, the control by means of a valve which can, with a given cycle, be able to direct hydraulic fluid to and from the activated cylinders, a reliable and convenient control is obtained.
Ved, som omhandlet i krav 4, at montere de enkelte trykplader på stempel-5 stangen ved hjælp af et snaplignende holdegreb opnås det, at trykpladerne let kan monteres.By, as defined in claim 4, mounting the individual pressure plates on the piston-5 by means of a snap-like holding grip, it is achieved that the pressure plates can be easily mounted.
Ved, som omhandlet i krav 5, at udforme en fordybning på trykpladens underside, hvorpå en kugleformet endepart på stempelstangen kan fast-10 gøres, opnås det, at trykpladen kan bevæges og dermed tilpasse sig kropsformen.By forming a recess on the underside of the pressure plate, on which a spherical end portion of the piston rod can be fixed, it is achieved that the pressure plate can be moved and thus adapt to the body shape.
Ved, som omhandlet i krav 6, at begrænse fordybningens udstrækning og dermed omkransningen af den kugleformede part på stemplestangen opnår 15 man, at trykpladen kan vippe og dermed let tilpasse sig de forskellige kropsformer.By limiting the extent of the recess and thus the circumference of the spherical part of the piston rod, as claimed in claim 6, it is achieved that the pressure plate can tilt and thus easily adapt to the different body shapes.
Endelig er det hensigtsmæssigt, som omhandlet i krav 7, at kunne afmontere en eller flere trykplader, f.eks. under sår eller andre skader på kroppen, 20 som ikke må belastes.Finally, it is appropriate, as claimed in claim 7, to be able to remove one or more pressure plates, e.g. during wounds or other injuries to the body, 20 which must not be loaded.
TegningenThe drawing
Et eksempel på en udførelsesform for et understøtningsapparat ifølge 25 opfindelsen vil i det følgende blive nærmere beskrevet under henvisning til tegningen, hvor fig. 1-3 i skematisk form viser, hvorledes to hosliggende understøtninger bevæges, 30 fig. 4 viser, hvorledes en trykplade, vist i snit, er monteret på enden af en stempelstang, og 4 DK 177100 B1 fig. 5 viser en understøtning set ovenfra med en skitseret ventil til styring af hydraulikstrømningerne til de enkelte cylindre.An example of an embodiment of a support apparatus according to the invention will now be described in more detail with reference to the drawing, in which fig. 1 to 3 show in schematic form how two adjacent supports are moved, FIG. 4 shows how a pressure plate, shown in section, is mounted on the end of a piston rod and 4 DK 177100 B1 fig. 5 is a top plan view of an outlined valve for controlling the hydraulic flows of the individual cylinders.
5 Beskrivelse af et udførelseseksempel5 Description of an Example
Det er som nævnt formålet med opfindelsen at forbedre blodstrømningen, og dette kan opnås ved hjælp af et understøtningsapparat, som vil blive forklaret under henvisning til fig. 1-3.As mentioned, the object of the invention is to improve blood flow and this can be achieved by means of a support apparatus which will be explained with reference to FIG. 1-3.

Understøtningen, som betegnes med 1, omfatter et antal cylindre 4, som er tilsluttet et hydraulisk kredsløb omfattende rørledninger 5 som antydet på fig. 5. Der tilledes hydrauliktryk til hver cylinder 4 under stemplet således, at alle stempler er i den højeste position, som eksempelvis på fig. 1, hvor dog 15 den ene cylinder B er nedsænket.The support, designated 1, comprises a plurality of cylinders 4 connected to a hydraulic circuit comprising piping 5 as indicated in FIG. 5. Hydraulic pressure is applied to each cylinder 4 below the piston so that all pistons are in the highest position, as shown in FIG. 1, however, one cylinder B is submerged.
Hvert stempel er forsynet med en stempelstang, som foroven bærer en trykplade 3, som vist på fig. 4. Samlingen mellem trykpladen 3 og stempelstangen 11 omfatter fortrinsvis en snaplignende kobling omfattende en 20 kuglepart 12, som sidder på den øverste ende af stempelstangen 11.Each piston is provided with a piston rod which carries a pressure plate 3 at the top, as shown in FIG. 4. The assembly between the pressure plate 3 and the piston rod 11 preferably comprises a snap-like coupling comprising a 20 ball portion 12 which sits on the upper end of the piston rod 11.
På undersiden af trykpladen 3 er der udformet en kugleudtagning, og da trykpladen 3 er fremstillet i et eftergiveligt materiale, vil væggen i udtagning kunne snappe omkring kuglen 12. På denne måde vil trykpladen 3 kunne 25 vippe som antydet med vinkelangivelsen 13, ligesom den vil kunne afmonteres, f.eks. som vist med stiplet streg 14 i fig. 5, hvor der måtte være behov for at undlade trykpåvirkning. Dette kunne være i tilfælde af, at brugeren har eller har risiko for sårdannelse og lignende.On the underside of the pressure plate 3 a ball recess is formed, and since the pressure plate 3 is made of a resilient material, the wall in recess can snap around the ball 12. In this way, the pressure plate 3 can tilt as indicated by the angular indication 13, just as it will could be removed, e.g. as shown by dashed line 14 in FIG. 5 where there is a need to avoid pressure exertion. This could be in case the user has or is at risk of ulceration and the like.
30 Over trykpladerne 3 forløber i det viste eksempel en pude eller et betræk 2 til udjævning af mellemrum mellem trykpladerne 3.30 In the example shown, a pad or cover 2 extends over the pressure plates 3 for leveling the spaces between the pressure plates 3.
5 DK 177100 B1 På tegningen er vist et snit gennem en kropsdel 8, som er den del af kroppen, som bliver understøttet af understøtningen.5 DK 177100 B1 The drawing shows a section through a body part 8 which is the part of the body which is supported by the support.
5 På fig. 1 er trykpladen på cylinder B nedsænket, mens de øvrige plader 3 er i deres højeste position. Blodet 9 vil derfor sive mod et punkt over den nedsænkede trykplade som antydet med krydsskravering.5 In FIG. 1, the pressure plate on cylinder B is submerged while the other plates 3 are in their highest position. The blood 9 will therefore seep towards a point above the submerged pressure plate as indicated by cross-hatching.
Efter et passende tidsrum vil en ventilindretning som vist på fig. 5 blive 10 omstillet til at hæve den nedsænkede plade 3 som antydet med pilen 7, samtidig med at den hosliggende cylinder A bliver sænket som vist med pilen 6. Dette skift vil medføre, at blodet 9 bliver drevet fra området over cylinder B hen til det nærliggende område over den nedsænkede cylinder A. Resultatet heraf ses på fig. 3, hvor den endelige position, hvor blodet 9 15 er sivet hen over trykpladen 3 på cylinder A og dermed har skiftet plads fra en position over cylinder B til en position over cylinder A.After a suitable period of time, a valve assembly as shown in FIG. 5, 10 is adjusted to raise the submerged plate 3 as indicated by arrow 7 while lowering the adjacent cylinder A as shown by arrow 6. This shift will cause the blood 9 to be driven from the area above cylinder B to it. adjacent area over the submerged cylinder A. The result of this is shown in FIG. 3, where the final position, where the blood 9 15 is seeped across the pressure plate 3 of cylinder A and thus has changed space from a position above cylinder B to a position above cylinder A.
På fig. 5 er vist et eksempel på en ventilindretning uden betræk 2 for at vise trykpladerne 3 i form af cirkler. Som det er forsøgt illustreret, er cylindrene 20 anbragt på række og således, at cylindre mærket A er anbragt i en lige linje ved siden af cylindre B til den ene side og cylindre F til den anden side, altså i det viste eksempel seks cylindre i en zone. Hver af disse zoner har eksempelvis 42 cylindre, som tilsammen danner en understøtning med 252 bevægelige trykplader.In FIG. 5 is an example of a valve assembly without cover 2 for showing the pressure plates 3 in the form of circles. As has been attempted to illustrate, the cylinders 20 are arranged in a row and so that cylinders labeled A are placed in a straight line next to cylinders B on one side and cylinders F on the other side, i.e. in the example shown, six cylinders in a zone. For example, each of these zones has 42 cylinders which together form a support with 252 movable pressure plates.
2525
En fordelerventil 10 med tilgang og afgang til og fra de enkelte cylindre 4 sikrer, at hydraulikvæske under tryk henholdsvis ledes til alle cylindre, fx mærket med A samtidigt med, at hydrauiikvæske ledes bort fra alle de hosliggende cylindre, fx mærket med B. Herved opnås den ønskede effek-30 tive blodstrømning mellem hosliggende understøtningspunkter, idet blodet strømmer i et ’lukket’ kredsløb, mens hosliggende stempler arbejder.A distributor valve 10 with inlet and outlet to and from the individual cylinders 4 ensures that hydraulic fluid is pressurized respectively to all cylinders, for example marked A at the same time as hydraulic fluid is discharged from all the adjacent cylinders, for example labeled B. the desired effective blood flow between adjacent support points, the blood flowing in a 'closed' circuit while adjacent pistons work.

For eksempel kan der anvendes en fordelerventil 10, hvori ventillegemet trinvis roteres af en stepmotor med en drivindretning, og hvor en pumpe fordeler væske ud og ind via udløbsåbninger på ventilen.For example, a distributor valve 10 may be used, in which the valve body is rotated stepwise by a stepper motor with a drive, and where a pump distributes fluid in and out via outlet openings on the valve.

Funktionen af understøtningen kan således sammenfattes som følger: ; Trykpladerne 3 med tilhørende cylindre 4 er inddelt i sæt med lige mange i hvert sæt, hvor et af sættene altid er nedsænket.The function of the support can thus be summarized as follows:; The pressure plates 3 with associated cylinders 4 are divided into sets with equal numbers in each set, where one of the sets is always submerged.
10 Når det sæt, der er nedsænket, f.eks. sæt B på fig. 1, skal fyldes, sker det ved, at det hosliggende sæt A afgiver sit indhold af hydraulikvæske til sæt B. Sæt A og B er under denne funktion ikke i hydraulisk forbindelse med de øvrige sæt C, D, E og F.10 When the set that is submerged, e.g. set B of FIG. 1, to be filled, it happens that the adjacent set A delivers its hydraulic fluid content to set B. During this function, sets A and B are not in hydraulic connection with the other sets C, D, E and F.
1515
Ved afslutningen af tømme-fylde-funktionen vil sæt B blive sat i forbindelse med sæt C, D, E og F, således at brugeren nu som vist på fig. 3 sidder eller ligger på sæt B, C, D, E og F, som er indbyrdes forbundet og derved giver en total trykudligning og samtidig indtager en form, der er fuldstændig til-20 passet brugerens anatomi.At the end of the empty-fill function, set B will be connected to sets C, D, E and F, so that the user now as shown in FIG. 3 sits or lies on sets B, C, D, E and F, which are interconnected, thereby providing a total pressure equalization and at the same time assuming a shape which is fully adapted to the user's anatomy.
Hele denne proces er styret af en ventil og tilhørende pumpeenhed.This entire process is controlled by a valve and associated pump unit.
Ved hjælp af dette udstyr kan enhver ønsket frekvens af bevægelserne af 25 cylindrene og dermed af blodstrømningen opnås ved hjælp af et enkelt og meget driftssikkert udstyr.By means of this equipment any desired frequency of the movements of the 25 cylinders and thus of the blood flow can be obtained by a simple and very reliable equipment.
