Description
Den foreliggende oppfinnelse vedrører en madrass, særlig for bruk ved behandling av pasienter, utstyrt med hulrom og en anordning for tilførsel av luft og innrettet til å avgi tilført luft. The present invention relates to a mattress, in particular for use in the treatment of patients, equipped with a cavity and a device for supplying air and arranged to emit supplied air.
Når en pasient skal komme seg igjen etter en omfattende operasjon er det ønskelig at legemet er omsluttet av et mikroklima, det vil si en omgivelse som inneholder behandlet luft. When a patient is recovering after an extensive operation, it is desirable that the body is surrounded by a microclimate, that is, an environment that contains treated air.
Denne luft kan være bakteriefri og ha regulert temperatur og fuktighet for å hindre for stort stoffskifte og avlaste pasientens hjerte eller alternativt påskynne legingen av for eksempel brann-sår . This air can be bacteria-free and have regulated temperature and humidity to prevent excessive metabolism and relieve the patient's heart or alternatively speed up the healing of, for example, burns.
Madrasser med tilførselsanordninger for luft er kjent fra Mattresses with supply devices for air are known from
DOS 1.910.954, US-patentskrift 2.493.067 samt britisk patentskrift 959.103. DOS 1,910,954, US patent 2,493,067 and British patent 959,103.
Fra US-patentskrift 3.148.391 er det kjent en madrass som From US patent 3,148,391, a mattress is known which
er utstyrt med hulrom hvis volum kan varieres ved regulering av trykket i hulrommene. is equipped with cavities whose volume can be varied by regulating the pressure in the cavities.
Det er et formål med den foreliggende oppfinnelse å frem-bringe en madrass hvorpå en pasient som for eksempel lider av sjokk, hypotermia eller forbrenninger, kan bæres mens legemet, It is an aim of the present invention to produce a mattress on which a patient suffering from, for example, shock, hypothermia or burns, can be carried while the body,
som kan være dekket av et laken, utsettes for et mikroklima av behandlet luft for å lette oppvåkningen, idet madrassen skal være forholdsvis billig å fremstille og ikke kreve stort luftforråd. which can be covered by a sheet, is exposed to a microclimate of treated air to facilitate waking up, as the mattress must be relatively cheap to manufacture and not require a large air supply.
Ifølge oppfinnelsen er det frembrakt en madrass som kjenne-tegnes av kombinasjonen av følgende trekk: According to the invention, a mattress has been produced which is characterized by the combination of the following features:
a) en blokk av elastisk materiale, a) a block of elastic material,
b) hule ribber som er anbrakt i det minste oppå blokken og b) hollow ribs placed at least on top of the block and
som omfatter et øvre lag av luftpermeabelt materiale forbundet med comprising an upper layer of air permeable material connected thereto
et nedre lag av lufépermeabelt materiale langs sømmer, samt a lower layer of loofah-permeable material along seams, as well as
c) innlegg av elastisk materiale som delvis fyller ribbene. c) inserts of elastic material that partially fill the ribs.
Madrass ifølge oppfinnelsen krever ikke et stort luftfor- The mattress according to the invention does not require a large air supply
råd idet blokken av elastisk materiale ikke gjennomstrømmes av advice as the block of elastic material is not flowed through
luften. Samtidig oppnås det et effektivt underlag for den person som ligger på madrassen. Madrassen ifølge oppfinnelsen er både rimelig og hensiktsmessig. the air. At the same time, an effective base is achieved for the person lying on the mattress. The mattress according to the invention is both reasonable and appropriate.
Med "behandlet luft" menes luft som kan være bakteriefri og ha en bestemt temperatur og fuktighet. By "treated air" is meant air that can be bacteria-free and have a specific temperature and humidity.
Det er fordelaktig at ribbene omfatter to par sideribber og en eller flere enderibber som er plassert under den upermeable om-kretskant på overdelen, og et flertall langsgående sentrale ribber plassert under det sentrale område av overdelen".^ 1 It is advantageous for the ribs to comprise two pairs of side ribs and one or more end ribs which are located below the impermeable peripheral edge of the upper part, and a plurality of longitudinal central ribs located below the central area of the upper part".^ 1
Sideribbene er. fortrinnsvis dypere" emf. sentralribbene slik at'det dannes en utsparing undrer' de "sentral é1 ribber' idet denne utsparing kan gi: plass" f or" den" elastiske"<1> blokk. Hele madrassen kan omfatte et ytre, trekk, av tekstilmateriale -som-' kan", gjennomtrenges av.luft, såsom dunlerret. " "! "i 'ra<1>" rc! The side ribs are. preferably deeper" e.g. the central ribs so that a recess is formed below the "central é1 ribs", since this recess can provide: space" for" the" elastic"<1> block. The entire mattress may comprise an outer cover of textile material which can be permeated by air, such as down canvas.
Oppfinnelsen vil bli beskrevet ytterligere;under: henvisning til den medfølgende tegning, hvori: Fig. 1 viser et perspektivriss fra oversiden av en foretrukket utførelsesform av en madrass ifølge oppfinnelsen. Fig. 2 viser et tverrsnitt i forstørret målestokk langs lin-jen II-II i fig. 1. The invention will be described further; under: reference to the accompanying drawing, in which: Fig. 1 shows a perspective view from the top of a preferred embodiment of a mattress according to the invention. Fig. 2 shows a cross-section on an enlarged scale along the line II-II in fig. 1.
En foretrukket utførelsesform av en madrass 9 ifølge oppfinnelsen omfatter en rektangulær overdel 10 og en tilsvarende rektangulær underdel 11 av fleksibelt plastmateriale. Disse deler er forbundet med hverandre langs omkretsen, for eksempel ved at de er fremstilt i ett stykke eller sveiset eller sydd sammen. Delene 10 og 11 er forbundet med et antall langsgående parallelle sømmer 12, idet hver søm<1>12 strekker seg fra et sted nær opp til, men i avstand fra en. ende av madrassen 9 til et sted nær opp til, men i avstand fra .den andre ende av madrassen. Det'vil således fremgå at sømmene 12 deler madrassen 9 i to par langsgående sideribber 13, 14 og 15,<J>16"og et"åhtåli<r>langsgående sentralribber 17. Delene har en enderibbe 18" og "en"'anne Agender ibbe i i', som" er?'plan. Omkrets-delen tiI"ov§rdelen 10, som er over enderibbene 18 og enderibben 19 og sideribbene 13, 14, 15, 16 er tett på samme måte som hele underdelen Il/meus et séhtralt' område 20rav éveråelen 10 over sen-tralribbéne 17<L>'er~forsynt'med åpninger 21 hvis formål'vil bli beskrevet nedenfor."' A preferred embodiment of a mattress 9 according to the invention comprises a rectangular upper part 10 and a corresponding rectangular lower part 11 of flexible plastic material. These parts are connected to each other along the circumference, for example by being produced in one piece or welded or sewn together. The parts 10 and 11 are connected by a number of longitudinal parallel seams 12, each seam<1>12 extending from a location close to but at a distance from one. end of the mattress 9 to a place close to, but at a distance from, the other end of the mattress. It will thus appear that the seams 12 divide the mattress 9 into two pairs of longitudinal side ribs 13, 14 and 15, 16 and a longitudinal central rib 17. The parts have an end rib 18 and another Agenda ibbe in i', which" is?'plan. The circumferential part of the upper part 10, which is above the end ribs 18 and the end rib 19 and the side ribs 13, 14, 15, 16 is closed in the same way as the entire lower part 1/meus a séhtralt' region 20rav évaräel 10 above the central ribs 17 <L>'is~provided'with openings 21 whose purpose'will be described below."'
Enderibbene 18 og 19 er forsynt med strimler 26 av såkalt "kardeborre"-materiale for å forenkle festingen av madrassen 9 til en bærer såsom en seng, med tilsvarende strimler. The end ribs 18 and 19 are provided with strips 26 of so-called "Velcro" material to facilitate the attachment of the mattress 9 to a carrier such as a bed, with corresponding strips.
I hver sentralribbe 17 er det anbrakt et innlegg 22 av skumplast, idet hvert innlegg har en tykkelse som er omtrent lik den tykkelse sentralribbene 17 ville innta med oppblåst madrass 9. In each central rib 17, an insert 22 of foam plastic is placed, each insert having a thickness that is approximately equal to the thickness the central ribs 17 would take with an inflated mattress 9.
Madrassens tilførselsanordning omfatter en samlemanifold (ikke vist) med lengde omtrent lik madrassens 9 bredde og som er plassert inne i enderibben 18. En ende 23 av manifoldet raa<p>r nt av en ende av enderibben 18. Et par tilførselsrør 24, 25 av elastisk skumplast strekker seg rettvinklet ut fra manifoldet- og er plassert inne i sideribbene 13 og 16. Fjærende rør 27 og 28 ;v elastisk skumplast er innlagt i sideribbene henholdsvis 14 og 15. The mattress supply device comprises a collecting manifold (not shown) with a length approximately equal to the width of the mattress 9 and which is placed inside the end rib 18. An end 23 of the manifold ra<p>r nt of one end of the end rib 18. A pair of supply pipes 24, 25 of elastic foam plastic extends at right angles from the manifold and is placed inside the side ribs 13 and 16. Resilient tubes 27 and 28; v elastic foam plastic is inserted in the side ribs 14 and 15 respectively.
Sideribbene 13, 14, 15, 16 er dypere enn ribbene 17 og den utsparing som derved dannes under ribbene 17 opptar en blokk 33 The side ribs 13, 14, 15, 16 are deeper than the ribs 17 and the recess that is thereby formed under the ribs 17 occupies a block 33
av elastisk skumplast, for eksempel for å gi en pasient på madrassen ytterligere støtte. of elastic foam plastic, for example to give a patient on the mattress additional support.
Rørene 24 og 2 5 har den åpne ende anordnet opp til enderibben 19 for å tilføre luft til denne og har en åpning nær opp til manifoldenden for tilførsel av luft til den ene enderibbe. Manifoldet kan under bruk være koblet til et forråd for behandlet luft, det vil si luft som har regulert temperatur og fuktighet og som kan være bakteriefri. The pipes 24 and 25 have the open end arranged up to the end rib 19 to supply air to this and have an opening close to the manifold end for supplying air to one end rib. During use, the manifold can be connected to a supply of treated air, i.e. air that has regulated temperature and humidity and can be bacteria-free.
Når en pasient bæres av madrassen 9 og lufttilførselen er koblet på, strømmer det luft ut av åpningen 21 i ribbene 17, og dette sikrer rikelig lufttilførsel til pasientens legeme. Selv om vekten av pasienten forsøker å trykke sammen ribbene 17, vil innleggene 22 av skumplast sikre, selv når de er fullstendig sammen-trykt, at det finnes luftkanaler 29 langs hver side av innleggene 22 slik at luften fremdeles kan nå pasienten. Tilførsel av luft krever omtrent 1,4 2 m^/min. When a patient is carried by the mattress 9 and the air supply is switched on, air flows out of the opening 21 in the ribs 17, and this ensures ample air supply to the patient's body. Although the weight of the patient tries to compress the ribs 17, the foam inserts 22 will ensure, even when fully compressed, that there are air channels 29 along each side of the inserts 22 so that air can still reach the patient. Supply of air requires approximately 1.4 2 m^/min.
For å sikre at madrassen 9 ikke forurenses av pasienten, om-gis den av et luftgjennomtrengelig madrasstrekk 30. Dette trekk 30 har form av en rektangulær sekk hvis overside 31 har små åpninger slik at den lett kan gjennomtrenges av luft som strømmer ut av åp-ningene 21 i madrassen 9, mens undersiden 32 er fremstilt av et tekstilmateriale som er mindre åpent vevet. Trekket 30 beskytter madrassen 9 mot forurensning av pasienten, men vil likevel til-late at luft fra madrassen 9 når pasientens legeme og kan strømme rundt dette. To ensure that the mattress 9 is not contaminated by the patient, it is surrounded by an air-permeable mattress cover 30. This cover 30 has the shape of a rectangular sack whose upper side 31 has small openings so that it can easily be penetrated by air flowing out of the the grooves 21 in the mattress 9, while the underside 32 is made of a textile material that is less open woven. The cover 30 protects the mattress 9 against contamination by the patient, but will still allow air from the mattress 9 to reach the patient's body and can flow around it.
Oppfinnelsen er ikke begrenset til de detaljer som er beskrevet foran, og variasjoner kan foretas innenfor rammen av patent-kravene. For eksempel trenger ikke ribbene ha det mønster som er beskrevet idet dette kan varieres og gis vilkårlig praktisk ut-forming. Madrassen kan være fremstilt av ethvert lufttett materiale, The invention is not limited to the details described above, and variations can be made within the scope of the patent claims. For example, the ribs do not need to have the pattern described as this can be varied and given any practical design. The mattress can be made of any airtight material,
såsom tettvevd tekstil eller plast. such as tightly woven textile or plastic.
Som et alternativ kan overdelen være fremstilt av luftgjennomtrengelig materiale, for eksempel et tekstilmateriale, og kan således-være virksomt perforert over hele sin utstrekning. As an alternative, the upper part can be made of air-permeable material, for example a textile material, and can thus be effectively perforated over its entire extent.
Tilførselsanordningen trenger ikke være utformet som beskrevet, og manifoldet kan være plassert utenfor og parallelt med ribben 18, idet et par slisser i ribben 18 tillater innføring av rør-ene 24 og 25 i sideribbene henholdsvis 13 og 16. Tilførselsanord-ningen kan omfatte et antall tilførselsrør for luft, som er til-koblet på forskjellige steder på omkretsen eller undersiden av madrassen. Sømmene 12 kan ha åpninger som tillater luft å passere lettere fra rørene 24, 25 til ribbene 17. The supply device does not have to be designed as described, and the manifold can be located outside and parallel to the rib 18, as a pair of slots in the rib 18 allow the introduction of the pipes 24 and 25 into the side ribs 13 and 16 respectively. The supply device can comprise a number supply pipes for air, which are connected at various places on the perimeter or underside of the mattress. The seams 12 may have openings that allow air to pass more easily from the tubes 24, 25 to the ribs 17.
Innleggene trenger ikke være kontinuerlige og hvert av dem kan omfatte et antall atskilte materialdeler anbrakt med innbyr-des avstand langs hver ribbe. Mange andre variasjoner er selv- The inserts do not have to be continuous and each of them can comprise a number of separate material parts placed at a distance from each other along each rib. Many other variations are self-
