Description
Kompress, fremgangsmåte til dennes fremstilling samt hylster for samme Compress, method for its manufacture and casing for the same
og fremgangsmåte til hylsterets fremstilling. and method for the casing's manufacture.
Foreliggende oppfinnelse vedrører The present invention relates to
kompresser for medisinske forbindinger, compresses for medical dressings,
bleier og lignende, samt også forløsnings-bind og lignende. En slik kompress består diapers and the like, as well as birth control pads and the like. Such a compress consists of
i prinsippet av et hylster og deri anbragt in the principle of a casing and placed therein
absorberende materiale. Oppfinnelsen går absorbent material. The invention goes
ført og fremst ut på en spesiell utførelse led primarily to a special execution
av hylsteret for slike kompresser. Videre of the casing for such compresses. Further
omfatter oppfinnelsen en fremgangsmåte the invention includes a method
ved kompressenes fremstilling. during the manufacture of the compresses.
Det er kjent ved bleier med et absorberende materiale som befinner seg i et It is known in the case of diapers with an absorbent material located in a
hylster å fremstille hylsteret på bleiens ene casing to produce the casing on one of the nappies
side av et fibermateriale, såsom papir, og side of a fibrous material, such as paper, and
en dermed forbundet folie av plast. Også a thus connected foil of plastic. Also
hylsterets annen side er her fremstilt av the case's other side is here made of
et våtstivet papir. En slik utførelse egner a wet stiffened paper. Such an embodiment is suitable
seg ikke for medisinske forbindinger bl. a. not for medical dressings, etc. a.
fordi papiret har tilbøyelighet til å sette because the paper has a tendency to set
seg fast i såret og hylsteret blir for luft-tett. En kompress med større anvendelighet get stuck in the wound and the sheath becomes too airtight. A compress with greater applicability
og som egner seg utmerket for medisinske and which is excellently suited for medical
forbindinger kan i henhold til oppfinnelsen dressings can according to the invention
oppnås når kompresshylsteret på den ene is achieved when the compression sleeve on the one
side, som er beregnet på å ligge an mot side, which is intended to rest against
kroppen, er forsynt med et væskegjennomslippelig sjikt som inneholder spredt liggende tråder eller fibrer, fortrinnsvis vevnad med forholdsvis vide masker, såsom the body, is provided with a liquid-permeable layer containing scattered threads or fibers, preferably woven with relatively wide meshes, such as
gasvevnad, forbundet med det førstnevnte gauze, associated with the former
sjikt under formidling av plastfolien, idet layer during dissemination of the plastic film, ie
denne folie fortrinnsvis befinner seg innerst this foil is preferably located in the innermost part
i hylsterets vegg. in the casing wall.
Ved å sette hylsteret sammen av en By putting the holster together from one
plastfolie og et sjikt av spredt liggende plastic film and a layer of scattered lying
tråder eller fibrer oppnås ikke bare en forbedret stabilitet og holdfasthet av kompressen, men fremfor alt muligheten av på en enkel måte å gjøre kompressen luftgjennomslippelig når den skal utføres, særlig for medisinske formål, hvor dette er fordelaktig eller nødvendig. Det er nemlig mulig å oppnå en perforering av den mot vevnaden eller fibersjiktet anliggende plastfolie alene ved å utsette det sammen-satte sjikt for varme og trykk i passende grad. De spredte tråder eller fibrer dan-ner mellom seg åpninger og vender mot den av termoplast bestående folie en ure-gelmessig flate, som ved trykkpåvirkning under den samtidige oppvarmning medfører at plastfolien gjennombrytes av meget fine hull. Plastfolien bør, særlig hvis den består av polyeten, være meget tynn, hensikts-messig ha en så liten tykkelse som 0,015— 0,03 mm. threads or fibers, not only an improved stability and holding strength of the compress is achieved, but above all the possibility of making the compress air-permeable in a simple way when it is to be performed, especially for medical purposes, where this is advantageous or necessary. Namely, it is possible to achieve a perforation of the plastic film which is adjacent to the fabric or fiber layer alone by exposing the composite layer to heat and pressure to an appropriate degree. The scattered threads or fibers form openings between them and face the foil consisting of thermoplastic an irregular surface, which, under the influence of pressure during the simultaneous heating, causes the plastic foil to be pierced by very fine holes. The plastic foil should, especially if it consists of polyethylene, be very thin, ideally with a thickness as small as 0.015-0.03 mm.
Det som utmerker fremgangsmåten ved fremstilling av kompresser av den foran angitte prinsipielle utførelse er først og fremst at den del av kompresshylsterets vegg som er sammensatt av plastfolie og væskegjennomslippelig sjikt utsettes for innvirkning av varme og trykk i en slik grad at plastfolien derved perforeres og blir luftgjennomslippelig. What distinguishes the method for the production of compresses of the aforementioned principle design is primarily that the part of the wall of the compress casing which is composed of plastic foil and a liquid-permeable layer is exposed to the influence of heat and pressure to such an extent that the plastic foil is thereby perforated and becomes air-permeable .
Når kompressen skal anvendes som sår-kompress eller plaster, kan det være fordelaktig å la den tynne plastfolien strekke seg også på kompressens innside og der forbindes med vevnaden, idet forbindingen istandbringes ved at vevnad- og foliesjikt sammenpresses ved en slik temperatur og méd et slikt trykk at plasten mykner og der oppstår hull i samme. When the compress is to be used as a wound compress or plaster, it can be advantageous to let the thin plastic film also extend on the inside of the compress and connect there with the tissue, as the dressing is established by compressing the tissue and foil layers at such a temperature and with such press that the plastic softens and holes appear in it.

Kompressene fremstilles i en sammen-hengende bane, fra hvilken de forskjellige kompresser senere kan adskilles. Hvorledes fremstillingen kan foregå, er i prinsippet anskueliggjort i fig. 3.

Pressvalsene 16, 17 er oppvarmet til en slik temperatur at plasten i banen 8 mykner og tjener som bindemiddel for å forbinde de ombrettede kantpartier med vevnaden samt også for å forbinde papirhanen med det absorberende materiale.
